This also includes some changes to use roundoff to detect convergence instead of fixed values. Also replaced some divisions with multiplication by a reciprocal. In addition, some of the optional arguments to advect_tracer that are only used for offline tracer advection were renamed or revised for clarity and reordered for the convenience of the non-offline-tracer code. Although answers with the offline tracer code will change slightly because of this refactoring, because of some bugs that were fixed in another recent commit, it was previously impossible to have run the offline tracer cases at all. All answers and output in the MOM6-examples regression suite are bitwise identical. --- src/tracer/MOM_offline_aux.F90 | 132 +++++++++++++++---------------- src/tracer/MOM_offline_main.F90 | 129 +++++++++++++++--------------- src/tracer/MOM_tracer_advect.F90 | 49 ++++++------ 3 files changed, 154 insertions(+), 156 deletions(-) diff --git a/src/tracer/MOM_offline_aux.F90 b/src/tracer/MOM_offline_aux.F90 index b370dd6bb4..f95f2cd40e 100644 --- a/src/tracer/MOM_offline_aux.F90 +++ b/src/tracer/MOM_offline_aux.F90 @@ -70,7 +70,7 @@ subroutine update_h_horizontal_flux(G, GV, uhtr, vhtr, h_pre, h_new) max(GV%Angstrom_H, 1.0e-13*h_new(i,j,k) - G%areaT(i,j)*h_pre(i,j,k)) !

(Pointers to an optics_type were already been used as the argument in all calls to optics_nbands(), but it was not always associated.) In two other routines, the change is simply to add a return call if there are 0 bands of shortwave radiation. With these changes, the single column test cases with no penetrating shortwave radiation now successfully run if PEN_SW_NBANDS = 0 and give answers that are identical to those obtained with PEN_SW_NBANDS = 1. All answers and output in cases that ran previously are bitwise identical, but there is a subtle change in a public interface. --- .../vertical/MOM_opacity.F90 | 19 +++++++++++++++---- 1 file changed, 15 insertions(+), 4 deletions(-) diff --git a/src/parameterizations/vertical/MOM_opacity.F90 b/src/parameterizations/vertical/MOM_opacity.F90 index 658170beda..9aa8fafd14 100644 --- a/src/parameterizations/vertical/MOM_opacity.F90 +++ b/src/parameterizations/vertical/MOM_opacity.F90 @@ -503,11 +503,15 @@ end subroutine extract_optics_fields !> Return the number of bands of penetrating shortwave radiation. function optics_nbands(optics) - type(optics_type), intent(in) :: optics !< An optics structure that has values of opacities + type(optics_type), pointer :: optics !< An optics structure that has values of opacities !! and shortwave fluxes. integer :: optics_nbands !< The number of penetrating bands of SW radiation - optics_nbands = optics%nbands + if (associated(optics)) then + optics_nbands = optics%nbands + else + optics_nbands = 0 + endif end function optics_nbands !> Apply shortwave heating below the boundary layer (when running with the bulk mixed layer inherited @@ -617,8 +621,10 @@ subroutine absorbRemainingSW(G, GV, US, h, opacity_band, nsw, optics, j, dt, H_l !

The model runs perfectly well in short offline-tracer test runs, and even gives bitwise identical output, perhaps because no layers were being abruptly flooded to 10^13 times their previous values. These omitted lines could change answers in some cases, so the lines in question have been retained in case the offline tracer code needs to be debugged layer and these mysterious (and seemingly unhelpful) lines turn out to have been necessary.

Also grouped the calls that allocate the memory that is still needed for diagnostics. This commit also includes a few other minor changes to clean up the documentation of variable intents and unit documentation in a handful of other places in the code: - Add intent declarations to the arguments to chksum2d() and chksum3d() - Corrected incorrect scale arguments for two (untested) checksum calls. - Corrected the documented units in several comments.

Because these por_face_area arrays are still 1 in all test cases, the answers are unchanged in any test cases from before a few weeks ago, but there could be answer changes in cases that are using the very recently added capability (in PR #3) to set fractional face areas. This change was discussed with Sam Ditkovsky, and agreed that there is no reason to keep the ability to recover the previous answers in any cases that use the recently added partial face width option. This commit also expanded the comments describing the h_u and h_v arguments to btcalc(), zonal_face_thickness(), and merid_face_thickness() routines, the diag_h[uv] elements of the accel_diag_ptrs type and the h_u and h_v elements of the BT_cont_type. All answers and output are bitwise identical in the MOM6-examples test suite and TC tests, but answer changes are possible in cases using a very recently added code option. --- src/core/MOM_barotropic.F90 | 20 ++++++++++++----- src/core/MOM_continuity_PPM.F90 | 39 +++++++++++++++++++------------- src/core/MOM_variables.F90 | 40 ++++++++++++++++++++------------- 3 files changed, 63 insertions(+), 36 deletions(-) diff --git a/src/core/MOM_barotropic.F90 b/src/core/MOM_barotropic.F90 index a7e8194a84..3cb1ebf399 100644 --- a/src/core/MOM_barotropic.F90 +++ b/src/core/MOM_barotropic.F90 @@ -3274,9 +3274,19 @@ subroutine btcalc(h, G, GV, CS, h_u, h_v, may_use_default, OBC) intent(in) :: h !< Layer thicknesses [H ~> m or kg m-2]. type(barotropic_CS), intent(inout) :: CS !< Barotropic control structure real, dimension(SZIB_(G),SZJ_(G),SZK_(GV)), & - optional, intent(in) :: h_u !< The specified thicknesses at u-points [H ~> m or kg m-2]. + optional, intent(in) :: h_u !< The specified effective thicknesses at u-points, + !! perhaps scaled down to account for viscosity and + !! fractional open areas [H ~> m or kg m-2].

This is far from the best implementation (e.g. read_variable_2d introduces another `broadcast` alongside the original one in the horizontal regridding) but it addresses the immediate issues with `MOM_read_data()`. * set default scale factor to 1 * add missing start/count arguments * Update MOM_io.F90 * Manage optional args in read_variable_2d This patch modifies read_variable_2d so that the size() tests of the optional arguments are applied before the call to nf90_get_var. The tests are also wrapped inside present() flags to avoid checking unassigned variables. Thanks to Robert Hallberg for the suggestions.

The changes include enforcing the MOM6-standard 2-point indentation convention, replacing 'if(A)' with 'if (A)', and changing logical comparison syntax like '.gt.' to '>' or '.eq.' to '=='. An old commented out block of code for debugging (detected by its use of non-standard syntax) was also eliminated.

Includes diagnostics for the pressure anomaly to verify. - Updates the Stokes time derivative to only be updated on dynamics time-steps. Adds additional storage of previous step that is also only updated on the dynamics time-steps. - Update so that the surface Stokes drift output when using the exponential surfbands option is the surface Stokes drift and not averaged over a layer near the surface. - Minor rename for clarity in Update_Surface_Waves using data_override to clarify the time that wave terms are computed. - Adds diagnostic tracking Stokes time tendency term for verification. - Updates Stokes diagnostic names for conformity. - Fix allocation of CS%STKy0 from u grid to v grid. --- src/core/MOM.F90 | 18 +- src/core/MOM_CoriolisAdv.F90 | 4 +- src/core/MOM_dynamics_split_RK2.F90 | 9 +- src/user/MOM_wave_interface.F90 | 462 ++++++++++++++++++---------- 4 files changed, 321 insertions(+), 172 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index e36e3f71d9..84873aed2c 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -657,16 +657,15 @@ subroutine step_MOM(forces_in, fluxes_in, sfc_state, Time_start, time_int_in, CS else CS%p_surf_end => forces%p_surf endif - if (CS%UseWaves) then !

This change eliminates a subtle array-syntax whole-array multiplication (by -1.) in one call to remap_all_state_vars (this clearly violated MOM6 code standards), and it corrects an actual sign error that will change answers (perhaps from a state of catastrophic failure) in the code for the REGRID_ACCELERATE_INIT=True option if REMAP_UV_USING_OLD_ALG is also true and the initial velocities that are being remapped are non-zero. Also added comments describing the real variables inside of remap_all_state_vars to help clarify what they do. Fortunately the situation where answers change seems like a very uncommon combination of settings (it is possible that no one has ever tried this), and all answers in the MOM6-examples test suite are bitwise identical. --- src/ALE/MOM_ALE.F90 | 56 ++++++++++++++++++++++++--------------------- 1 file changed, 30 insertions(+), 26 deletions(-) diff --git a/src/ALE/MOM_ALE.F90 b/src/ALE/MOM_ALE.F90 index 41ee555c52..72afad16df 100644 --- a/src/ALE/MOM_ALE.F90 +++ b/src/ALE/MOM_ALE.F90 @@ -378,7 +378,7 @@ subroutine ALE_main( G, GV, US, h, u, v, tv, Reg, CS, OBC, dt, frac_shelf_h) call diag_update_remap_grids(CS%diag) endif !

It appears hrat_min(I,J) can be zero. Reading the code, it makes sense that hrat_min can be zero. The division was previously made conditional in 14971b41024b96eda983 also when using backscatter, but then only one part of the denomitor was used in the conditional. - I'm not sure why the backscatter setup is repeatedly hitting these edge cases or specific line of code. - This fix uses the entire denominator in the conditional. --- src/parameterizations/lateral/MOM_hor_visc.F90 | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/parameterizations/lateral/MOM_hor_visc.F90 b/src/parameterizations/lateral/MOM_hor_visc.F90 index 6a9b49683c..323c0ceb65 100644 --- a/src/parameterizations/lateral/MOM_hor_visc.F90 +++ b/src/parameterizations/lateral/MOM_hor_visc.F90 @@ -1308,8 +1308,8 @@ subroutine horizontal_viscosity(u, v, h, diffu, diffv, MEKE, VarMix, G, GV, US, if (Kh(i,j) >= hrat_min(i,j) * CS%Kh_Max_xy(I,J)) then visc_bound_rem(i,j) = 0.0 Kh(i,j) = hrat_min(i,j) * CS%Kh_Max_xy(I,J) - elseif (CS%Kh_Max_xy(I,J)>0.) then visc_bound_rem(i,j) = 1.0 - Kh(i,j) / (hrat_min(i,j) * CS%Kh_Max_xy(I,J)) + elseif (hrat_min(I,J)*CS%Kh_Max_xy(I,J)>0.) then endif endif From e63c4055a4f12b862abac12f4ce4657495d0a7af Mon Sep 17 00:00:00 2001 From: Alistair Adcroft Date: Fri, 21 Jan 2022 09:27:59 -0500 Subject: [PATCH 0075/1329] Fix soft-conventional index capitalization in horizontal_viscosity() - A previous re-factor for optimization introduced some inconsistent capitalization.

The solution we employ is to use the maximum mixing coefficient of the two +contributions, + +\f[ + K (z) = \max (K_{ePBL} (z), K_{JHL} (z)), +\f] + +where \f$m_\ast\f$ (and hence \f$K_{ePBL}\f$) is constrained to be small as \f$|f| +\rightarrow 0\f$. This form uses the JHL mixing coefficient when the ePBL coefficient is +small. + +This approach is reasonable when the wind-driven mixing dominates, since both JHL and ePBL +give a similar solution when deployed optimally. One weakness of this approach is the +tropical region, where the shear-driven ePBL \f$m_\ast\f$ coefficient is not formulated. +The JHL parameterization is skillful to simulate this mixing, but does not include the +contribution of convection. The convective portion of \f$K_{ePBL}\f$ should be combined +with \f$K_{JHL}\f$ in the equatorial region when shear and convection occur together. +Future research is warranted. + +Finally, one should note that the mixing coefficient here (\f$K\f$) is used for both +diffusivity and viscosity, implying a turbulent Prandtl number of 1.0. + +\subsection subsection_Langmuir Langmuir circulation + +While only briefly alluded to in \cite reichl2018, the MOM6 code implementing ePBL does +support the option to add a Langmuir parameterization. There are in fact two options, both +adjusting \f$m_\ast\f$. */ From 3dbf2f58dc29898492f1a9b72e80d1454685f1b1 Mon Sep 17 00:00:00 2001 From: Kate Hedstrom Date: Wed, 6 Oct 2021 14:53:52 -0800 Subject: [PATCH 0109/1329] Undoing some patches from others --- src/core/MOM_barotropic.F90 | 32 +++------------------ src/framework/MOM_horizontal_regridding.F90 | 9 ------ 2 files changed, 4 insertions(+), 37 deletions(-) diff --git a/src/core/MOM_barotropic.F90 b/src/core/MOM_barotropic.F90 index 3cb1ebf399..cf001fc1d0 100644 --- a/src/core/MOM_barotropic.F90 +++ b/src/core/MOM_barotropic.F90 @@ -225,10 +225,7 @@ module MOM_barotropic !! pressure [nondim].

This was incompatible with the history of the function, which had previously required a fourth time axis (of one record), then was later modified to not require this axis. As a result, there are now files in use both with and without a time axis. This patch relaxes this check to ensure that the read is quasi-2d, i.e. the first two axes can read a segment of a 2d field, but will now reshape the start and nread arrays to match the field being read. Some additional checks are also added to ensure that it only reads one 2d slice. --- src/framework/MOM_io.F90 | 107 ++++++++++++++++++++++++++++++++------- 1 file changed, 89 insertions(+), 18 deletions(-) diff --git a/src/framework/MOM_io.F90 b/src/framework/MOM_io.F90 index 2ea19df183..8928d2e56b 100644 --- a/src/framework/MOM_io.F90 +++ b/src/framework/MOM_io.F90 @@ -892,9 +892,17 @@ end subroutine read_variable_1d_int !> Read a 2d array from a netCDF input file and save to a variable. !! -!!

If there are overlaps in scaling factors for different units, this also identifies and suggests alternate scaling factors with less overlaps. This commit includes the introduction of the new publicly visible routines check_scaling_factors(), scales_to_powers() and check_MOM6_scaling_factors. This new capability does not do anything for sufficiently low levels of model verbosity, and it is silent if the scaling factors are unique, or if less than 2 dimensions are being rescaled. All answers and output files are bitwise identical, but there can be additional messages to stdout. --- src/core/MOM.F90 | 3 + src/core/MOM_check_scaling.F90 | 221 +++++++++++++++++ src/framework/MOM_scaling_check.F90 | 353 ++++++++++++++++++++++++++++ 3 files changed, 577 insertions(+) create mode 100644 src/core/MOM_check_scaling.F90 create mode 100644 src/framework/MOM_scaling_check.F90 diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index c36c0545e1..4a82eac903 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -56,6 +56,7 @@ module MOM use MOM_ALE_sponge, only : rotate_ALE_sponge, update_ALE_sponge_field use MOM_barotropic, only : Barotropic_CS use MOM_boundary_update, only : call_OBC_register, OBC_register_end, update_OBC_CS +use MOM_check_scaling, only : check_MOM6_scaling_factors use MOM_coord_initialization, only : MOM_initialize_coord use MOM_diabatic_driver, only : diabatic, diabatic_driver_init, diabatic_CS, extract_diabatic_member use MOM_diabatic_driver, only : adiabatic, adiabatic_driver_init, diabatic_driver_end @@ -2285,6 +2286,8 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, restart_CSp, & endif ! dG_in is retained for now so that it can be used with write_ocean_geometry_file() below. + if (is_root_PE()) call check_MOM6_scaling_factors(CS%GV, US) + call callTree_waypoint("grids initialized (initialize_MOM)") call MOM_timing_init(CS) diff --git a/src/core/MOM_check_scaling.F90 b/src/core/MOM_check_scaling.F90 new file mode 100644 index 0000000000..b707b65bc9 --- /dev/null +++ b/src/core/MOM_check_scaling.F90 @@ -0,0 +1,221 @@ +!> This module is used to check the scaling factors used by the MOM6 ocean model +module MOM_check_scaling + +!

The internal representations of dimensional variables are +rescaled by integer powers of 2 that depend on their units, with all input and +output being rescaled back to their original MKS units. By choosing different +powers of 2 for different units, the internal representations with different +units scale differently, so dimensionally inconsistent expressions will not +reproduce, but dimensionally inconsistent expressions give bitwise identical +results. So, for example, if horizontal lengths scale by a factor of 2^6=64, +and time is scaled by a factor of 2^4=16, horizontal velocities will scale by a +factor of 2^(6-4)=4. In this case, expressions that combine velocities, all +terms would scale by the same factor of 4. By contrast, if there were an +expression where a variable with units of length were added to one with the +units of a velocity, the results would scale inconsistently, and answers would +change with different scaling factors. + + What makes these integer powers of 2 special is the way that floating point +numbers are written as an O(1) mantissa times 2 raised to an integer exponent +between +/-1024. Multiplication by an integer power of 2 is just an integer +shift in the exponent, so as long as the model is not rescaled by an overly +large factor to encounter overflows and the model is not relying on automatic +underflows being converted to 0, all floating point operations can be carried +with one scale, and then rescaled to obtain identical answers. MOM6 has the +option to explicitly handle all relevant cases of underflows, and it can be +demonstrated to give identical answers when each of its units are scaled by +factors ranging from 2^-140 ~= 7.2e-43 to 2^140 ~= 1.4e42. + + When running with rescaling factors other than 2^0 = 1, there are some extra +array copies and multiplies of input fields or diagnostic output, so it is +slightly more efficient not to actively use the dimensional rescaling. For +production runs, we typically set all of the rescaling powers to 0, but for +debugging code problems, this rescaling can be an invaluable tool, especially +when combined with the very verbose runtime setting DEBUG=True in a MOM_input or +MOM_override file. Diffs of the output from runs with different scaling factors +readily highlights the earliest instances of differences, which can be used to +track down any dimensionally inconsistent expressions. Similarly, dimensional +inconsistencies in diagnostics is easily tracked down by comparing the output +from a pair of runs. + + All real variables in MOM6 should have comments describing their purpose, +along with their rescaled units and their mks counterparts with notation like +"! A velocity [L T-1 ~> m s-1]". If the units vary with the Boussinesq +approximation, the Boussinesq variant is given first. When variables are read +in, their dimensions are usually specified with a 'scale=' optional argument on +the MOM_get_param or MOM_read_data call, while the unscaling of diagnostics is +specified with a 'conversion=' factor. In both cases, these arguments it next +to a text string specifying the variable's units, which can then be check easily +for self-consistency. + + Currently in MOM6, the following dimensions have unique scaling, along with +the notation used to describe these variables in comments: + +\li Time, scaled by 2^T_RESCALE_POWER, denoted as [T ~> s] +\li Horizontal length, scaled by 2^L_RESCALE_POWER, denoted as [L ~> m] +\li Vertical height, scaled by 2^Z_RESCALE_POWER, denoted as [Z ~> m] +\li Vertical thickness, scaled by 2^H_RESCALE_POWER, denoted as [H ~> m or kg m-2] +\li Density, scaled by 2^R_RESCALE_POWER, denoted as [R ~> kg m-3] +\li Enthalpy (or heat content), scaled by 2^Q_RESCALE_POWER, denoted as [Q ~> J kg-1] + + These rescaling capabilities are also used by the SIS2 sea ice model, but it +does uses a non-Boussinesq mass scale of [R Z ~> kg m-2] for ice thicknesses, +rather than having a separate scaling factor (of [H ~> m or kg m-2]) that varies +between the Boussinesq and non-Boussinesq modes like MOM6 does. The actual +powers used in the scaling are specified separately for MOM6 and SIS2 and +need not be the same. + + Each of these units can be scaled in separate test runs, or all of them can be +rescaled simultaneously. In the latter case, MOM_unique_scales.F90 provides +tools to evaluate whether the specific combinations of units used by a model +scale by unique powers, and it can suggest scaling factors that provides unique +combinations of rescaling factors for the dimensions being tested, using a +cost-function based on the frequency with which units are used in the model (and +specified inside of MOM_check_scaling.F90), with a cost going as the product of +the frequency of units that resolve to the same scaling factor. + + A separate set of scaling factors could also be used for different chemical +tracer concentrations, for example. In this case, the tools in +MOM_unique_scales.F90 could still be used, but there would need to be a separate +equivalent of the unit_scaling_type with variables that are appropriate to the +units of the tracers. + +*/ From 035ae5c85f3f96acfa8291e8a2537548f8b88b41 Mon Sep 17 00:00:00 2001 From: Alper Altuntas Date: Tue, 15 Feb 2022 16:13:32 -0700 Subject: [PATCH 0117/1329] Misc dimensional consistency fixes in regridding, remapping, and MEKE routines --- src/ALE/MOM_regridding.F90 | 9 ++++++++- src/framework/MOM_diag_remap.F90 | 2 +- src/parameterizations/lateral/MOM_MEKE.F90 | 2 +- 3 files changed, 10 insertions(+), 3 deletions(-) diff --git a/src/ALE/MOM_regridding.F90 b/src/ALE/MOM_regridding.F90 index 35dcdaa819..348d72683e 100644 --- a/src/ALE/MOM_regridding.F90 +++ b/src/ALE/MOM_regridding.F90 @@ -488,7 +488,6 @@ subroutine initialize_regridding(CS, GV, US, max_depth, param_file, mdl, coord_m call setCoordinateResolution(dz, CS, scale=1.0) elseif (coordinateMode(coord_mode) == REGRIDDING_RHO) then call setCoordinateResolution(dz, CS, scale=US%kg_m3_to_R) - CS%coord_scale = US%R_to_kg_m3 elseif (coordinateMode(coord_mode) == REGRIDDING_ADAPTIVE) then call setCoordinateResolution(dz, CS, scale=GV%m_to_H) CS%coord_scale = GV%H_to_m @@ -498,6 +497,14 @@ subroutine initialize_regridding(CS, GV, US, max_depth, param_file, mdl, coord_m endif endif + ! set coord_scale for RHO regridding independent of allocation status of dz + if (coordinateMode(coord_mode) == REGRIDDING_RHO) then + CS%coord_scale = US%R_to_kg_m3 + endif + + ! ensure CS%ref_pressure is rescaled properly + CS%ref_pressure = (US%kg_m3_to_R * US%m_s_to_L_T**2) * CS%ref_pressure + if (allocated(rho_target)) then call set_target_densities(CS, US%kg_m3_to_R*rho_target) deallocate(rho_target) diff --git a/src/framework/MOM_diag_remap.F90 b/src/framework/MOM_diag_remap.F90 index bb11d92673..15f50e5116 100644 --- a/src/framework/MOM_diag_remap.F90 +++ b/src/framework/MOM_diag_remap.F90 @@ -222,7 +222,7 @@ subroutine diag_remap_configure_axes(remap_cs, GV, US, param_file) allocate(interfaces(remap_cs%nz+1)) allocate(layers(remap_cs%nz)) - interfaces(:) = getCoordinateInterfaces(remap_cs%regrid_cs) + interfaces(:) = getCoordinateInterfaces(remap_cs%regrid_cs, undo_scaling=.true.) layers(:) = 0.5 * ( interfaces(1:remap_cs%nz) + interfaces(2:remap_cs%nz+1) ) remap_cs%interface_axes_id = MOM_diag_axis_init(lowercase(trim(remap_cs%diag_coord_name))//'_i', & diff --git a/src/parameterizations/lateral/MOM_MEKE.F90 b/src/parameterizations/lateral/MOM_MEKE.F90 index 5efb318db1..f677e03c21 100644 --- a/src/parameterizations/lateral/MOM_MEKE.F90 +++ b/src/parameterizations/lateral/MOM_MEKE.F90 @@ -709,7 +709,7 @@ subroutine MEKE_equilibrium(CS, MEKE, G, GV, US, SN_u, SN_v, drag_rate_visc, I_m SN = min(SN_u(I,j), SN_u(I-1,j), SN_v(i,J), SN_v(i,J-1)) if (CS%MEKE_equilibrium_alt) then - MEKE%MEKE(i,j) = (CS%MEKE_GEOMETRIC_alpha * SN * US%Z_to_m*depth_tot(i,j))**2 / cd2 + MEKE%MEKE(i,j) = (CS%MEKE_GEOMETRIC_alpha * SN * US%Z_to_L*depth_tot(i,j))**2 / cd2 else FatH = 0.25*((G%CoriolisBu(I,J) + G%CoriolisBu(I-1,J-1)) + & (G%CoriolisBu(I-1,J) + G%CoriolisBu(I,J-1))) !

Although this is not know to have caused any particular problems, these inconsistencies could lead to segmentation faults in cases where the target grid (e.g., diagnostic output) is larger than the input grid (e.g., the model's native grid). In some cases, certain grid generation options were only written to work with the same size of input and output grids, and error handling has been added to these cases to gracefully bring down the model if they are used with different grid sizes. All answers are bitwise identical in the MOM6-examples test suite, but it is conceivable that this could correct subtle (memory-related) issues in some configurations. --- src/ALE/MOM_regridding.F90 | 108 +++++++++++++++++++++++-------------- 1 file changed, 67 insertions(+), 41 deletions(-) diff --git a/src/ALE/MOM_regridding.F90 b/src/ALE/MOM_regridding.F90 index 94d7852851..dafd165245 100644 --- a/src/ALE/MOM_regridding.F90 +++ b/src/ALE/MOM_regridding.F90 @@ -3,7 +3,7 @@ module MOM_regridding !

By design, all logging of parameters after this commit is identical to before, even for variables that are inactive and therefore should not be logged. In several places, there were some problems, mostly with the GME code, that have been noted in comments marked with '###'. Also cleaned up the code alignment and eliminated unneeded temporary variables in a few places in hor_visc(). All solutions are bitwise identical, and no output is changed. * Move call to get get_KH outside k-loop The call to get the 3-d GME diffusivity arrays and the subsequent blocking halo update was moved outside of the k-loop. * Increase loop range for calculation of GME fluxes * Makes GME filter rotationally invariant * Makes the GME filter rotationally invariant * Adds a runtime param to allow the user to control how many smoothing passes should be done. * Rearranges the get_param calls related to Leith The get_param calls for Leith were not in the correct location. This commit fixes that. * Adding halo updates * Fixes do loops indices and adds diagnostics * Adds option to save barotropic tension and strain; * Fixes many i and j loops indices associated with GME to avoid halo problems and unnecessary halo updates. With these changes, the model is now conserving mass and tracers when USE_GME = True. * Fixes issues related to the merging with dev/gfdl * Fixes calculation of FrictWork_GME The calculation now mimics the calculation of FrictWork and it includes the energy diffusion term. * Removes dependency of FrictWork_GME calculation on MEKE * Adding sh_xy_sq and sh_xx_sq in the OMP directives Co-authored-by: Robert Hallberg --- .../lateral/MOM_hor_visc.F90 | 254 ++++++++++-------- 1 file changed, 145 insertions(+), 109 deletions(-) diff --git a/src/parameterizations/lateral/MOM_hor_visc.F90 b/src/parameterizations/lateral/MOM_hor_visc.F90 index 0249f79c2d..78f48975e5 100644 --- a/src/parameterizations/lateral/MOM_hor_visc.F90 +++ b/src/parameterizations/lateral/MOM_hor_visc.F90 @@ -2,14 +2,14 @@ module MOM_hor_visc !

This involves changes to the type of an argument (from real to EFP_type) for two arguments to the internal routine store_stocks. Existing tracer stock packages will still work, but to benefit from the reproducing sums, they will also have to change their reported values from real to EFP_type. This is demonstrated for two packages (advection_test_tracer and ideal_age_example), where the stocks are now found with calls to global_mass_int_EFP(), replacing the previous explicit sums. With this change, the reported stock values from these packages are identical for different PE layouts and can be much more accurate than before, but they are different from the previously reported values at roundoff (for positive-definite tracers), but it could be larger for tracers with a near-zero mean value.

It includes the following API changes: - Removal of `static_value` from `get_param` - Redefined `link_parameter` and `parameter_block` as private - New functions: `all_across_PEs()`, `any_across_PEs()` `static_value` was not used in any known experiments (outside of internal GFDL testing), and the two derived types describe internal operations within `MOM_file_parser`, so we do not expect any disruptions from these changes. A detailed summary of the changes are listed below. - `assert()` is now used to detect same files with different IO units. Detection of reopenend files of the same name but different IO unit has been changed from `MOM_error(FATAL, ...)` to `assert()`, to reflect that this should be a logically impossible result. - Bugfix: Reopened files are now reported to all PEs. If an open file is re-opened, then only the root PE will detect this and will `return` immediately. However, the others will proceed into `populate_param_data` and will get stuck in a broadcast waiting for root. We fix this by communicating the reopened state to all PEs and allow all ranks to return before re-processing the data. Note that this could also be resolved by allowing all ranks to track IO unit numbers, but for now we do not attempt to change this behavior. - `newunit=` used to generate parameter file IO unit The parameter IO unit is now generated by `newunit=` rather than an explicit search for an unused IO unit. Note that this is a Fortran 2008 feature. Testing around available IO units has also been removed. - Removal of generic IO error handling Generic "IO error" tests, and corresponding `err=` arguments, have been removed in most cases. We now rely on the Fortran runtime to provide diagnostics on these errors, which should typically exceed any information that MOM6 could provide. - Removal of purported `namelist` support There were several blocks of code provided to support namelist syntax, but did not appear to be working, nor was there any known instance of it being used by anyone, so it has been removed. - `#define/undef/=` syntax testing across ranks Previously, only the root PE would test for consistency of the #define-like syntax, even though all ranks have this information. This required a second, awkwardly placed syntax test later in the subroutine. This test is redefined to run over all ranks, and the subsequent test has been removed. - `define/override` test reordering The `found_override` test when coupled to a `#define`-like declaration was unreachable due to the presence of an even stronger test related to valid syntax. This test has been moved to provide more detailed information about the nature of the error. - `link_parameter`, `parameter_block` defined as private Internal derived types of `MOM_file_parser` are redefined as private. This preserves the integrity of instances of these types, and also prevents creation of implicit object code required to access them externally. - Removal of `static_value` from `get_param` interface The `static_value` argument of `get_param` has been removed, since it is functionally equivalent to `default`. While this is an API change, there is no known case of anyone using this argument. - The `param_type%doc` fields are now properly deallocated after closed. - Quotes have been added around some filename error warnings, to help detect issues related to whitespace. - `any_across_PEs` and `all_across_PEs` New functions for calling `any()` and `all()` across PE ranks have been added. Behavior is in line with other functions, such as `min_across_PEs`. --- config_src/infra/FMS1/MOM_coms_infra.F90 | 31 ++++ config_src/infra/FMS2/MOM_coms_infra.F90 | 31 ++++ src/core/MOM_verticalGrid.F90 | 2 +- src/framework/MOM_coms.F90 | 2 + src/framework/MOM_domains.F90 | 8 +- src/framework/MOM_file_parser.F90 | 186 +++++++---------------- 6 files changed, 123 insertions(+), 137 deletions(-) diff --git a/config_src/infra/FMS1/MOM_coms_infra.F90 b/config_src/infra/FMS1/MOM_coms_infra.F90 index 555b4df119..561cf6c333 100644 --- a/config_src/infra/FMS1/MOM_coms_infra.F90 +++ b/config_src/infra/FMS1/MOM_coms_infra.F90 @@ -16,6 +16,7 @@ module MOM_coms_infra public :: PE_here, root_PE, num_PEs, set_rootPE, Set_PElist, Get_PElist public :: broadcast, sum_across_PEs, min_across_PEs, max_across_PEs +public :: any_across_PEs, all_across_PEs public :: field_chksum, MOM_infra_init, MOM_infra_end !

By default, all answers are bitwise identical, but there are several new runtime parameters. The code changes include: . Added the ability to use a different remapping scheme for velocities than for tracers, using the new runtime parameter VELOCITY_REMAPPING_SCHEME . Added the new runtime option PARTIAL_CELL_VELOCITY_REMAP to use partial cell thicknesses for remapping at velocity points, which triggers a call to the new internal routine apply_partial_cell_mask. . Added the new internal routine mask_near_bottom_vel to allow MOM6 to mimic Hycom in zeroing out the velocities in thin layers in a bottom boundary layer with a thickness given by the new runtime parameter REMAP_VEL_MASK_BBL_THICK, while the definition of thin is specified by REMAP_VEL_MASK_H_THIN. Setting these to be negative (as is the default) avoids this. . Modified the interface to remap_all_state_vars to take just the ALE_CS, which then provides the remapping control structure that is appropriate for the tracers or velocities, rather than also passing this in as an argument. . Eliminated some unnecessary internal variables, and added others to be more explicit avoid array syntax copies in arguments. --- src/ALE/MOM_ALE.F90 | 348 ++++++++++++++++++++++++++++++-------------- 1 file changed, 239 insertions(+), 109 deletions(-) diff --git a/src/ALE/MOM_ALE.F90 b/src/ALE/MOM_ALE.F90 index 72afad16df..46669c20cb 100644 --- a/src/ALE/MOM_ALE.F90 +++ b/src/ALE/MOM_ALE.F90 @@ -10,7 +10,7 @@ module MOM_ALE !

From 464046138500854a95a0e7f89ac1677e71c8462a Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Thu, 24 Feb 2022 13:51:55 -0500 Subject: [PATCH 0135/1329] (*)Avoid negative thicknesses in mixed_layer_restrat Enforce a minimum thickness of 0.5*Angstrom in the mixed_layer_restrat routines. The streamfunctions in these routines attempt to limit the thicknesses to exceed Angstrom, but they can be less than this due to roundoff. The new limit prevents thicknesses from becoming negative when Angstrom is set to 0, but should not change any answers for test cases with positive values of Angstrom. Also added some comments describing variables and their units and simplified the OMP directives. Also corrected error messages in MOM_diabatic_aux.F90 to identify the file or module where these messages come from, and modified an error message in applyTracerBoundaryFluxesInOut so that it is written if the localized fault does not happen to occur on the root PE. All answers in the existing MOM6-examples regression suite are bitwise identical. --- .../lateral/MOM_mixed_layer_restrat.F90 | 85 ++++++++++--------- .../vertical/MOM_diabatic_aux.F90 | 12 +-- src/tracer/MOM_tracer_diabatic.F90 | 2 +- 3 files changed, 50 insertions(+), 49 deletions(-) diff --git a/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 b/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 index 04982d7171..6176f4aa1d 100644 --- a/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 +++ b/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 @@ -156,15 +156,16 @@ subroutine mixedlayer_restrat_general(h, uhtr, vhtr, tv, forces, dt, MLD_in, Var real :: u_star ! surface friction velocity, interpolated to velocity points [Z T-1 ~> m s-1]. real :: mom_mixrate ! rate at which momentum is homogenized within mixed layer [T-1 ~> s-1] real :: timescale ! mixing growth timescale [T ~> s] + real :: h_min !

Dynamic memory builds would have been unaffected by this, and older GCC (~7.3.0) compilers appear to have not objected to the shape mismatch, but this raised an error in newer GCCs (~9.3.0).

To support this, some of the KPP diagnostics were moved from the KPP_CS type to the tracer_type data structure and the KPP_NonLocalTransport_temp() and KPP_NonLocalTransport_saln() functions were refactored to put common code in KPP_NonLocalTransport() (which can be called from any of the tracer modules). Additionally, scaling terms for the diagnostics available from the KPP_NonLocalTransport() function are encoded via the conversion argument of the register_diag_field() call in register_tracer_diagnostics(). This results in a round-off level change to the KPP_NLT_temp_budget and KPP_NLT_saln_budget diagnostics. Lastly, two structural changes to the code: 1. To avoid a circular dependency between MOM_variables.F90 and MOM_tracer_registry.F90, tracer_type and tracer_registry_type have been moved to a new module named MOM_tracer_types.F90. Both of those types remain public in MOM_tracer_registry.F90, so they are still available through "use MOM_tracer_registry" statements. 2. Some code in MOM_CFC_cap.F90 was refactored to replace nearly-repeated lines (first for CFC11 and then for CFC12) with loops over an array of the new CFC_tracer_metadata type. This PR does not change answers for MOM6-examples when compared against MOM6/main. There is a minor change in MOM_parameter_doc.all for the following tests because the description of APPLY_NONLOCAL_TRANSPORT has been updated: ``` ocean_only/CVmix_SCM_tests/cooling_only/KPP/ ocean_only/CVmix_SCM_tests/mech_only/KPP/ ocean_only/CVmix_SCM_tests/skin_warming_wind/KPP/ ocean_only/CVmix_SCM_tests/wind_only/KPP/ ocean_only/SCM_idealized_hurricane/ ocean_only/SCM_idealized_hurricane/ ocean_only/single_column/EPBL/ ocean_only/single_column/KPP/ ``` --- src/core/MOM.F90 | 13 +- src/core/MOM_forcing_type.F90 | 29 ++- src/core/MOM_variables.F90 | 3 + .../vertical/MOM_CVMix_KPP.F90 | 210 +++++++----------- .../vertical/MOM_diabatic_driver.F90 | 40 ++-- src/tracer/MOM_CFC_cap.F90 | 190 +++++++++------- src/tracer/MOM_tracer_flow_control.F90 | 21 +- src/tracer/MOM_tracer_registry.F90 | 209 ++++++----------- src/tracer/MOM_tracer_types.F90 | 130 +++++++++++ src/tracer/pseudo_salt_tracer.F90 | 18 +- 10 files changed, 479 insertions(+), 384 deletions(-) create mode 100644 src/tracer/MOM_tracer_types.F90 diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 31718ae37b..e2e966e3b4 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -1834,6 +1834,7 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, restart_CSp, & integer :: first_direction !

This is accomplished by the new internal subroutine add_interface_KH, and is controlled by the new runtime parameters KH_ETA_CONST and KH_ETA_VEL_SCALE. The new interface diffusivities are subject to CFL bounding when combined with the previous isopycnal slope diffusivities, with the two diffusivities reduced proportionately when the CFL limits are exceeded. Also simplified many openMP directives in MOM_thickness_diffuse.F90, and fixed a number of spelling errors or other problems in comments, including adding units to some variables. By default, all answers are bitwise identical, although there are new runtime parameters a new internal subroutine. --- .../lateral/MOM_thickness_diffuse.F90 | 438 +++++++++++------- 1 file changed, 260 insertions(+), 178 deletions(-) diff --git a/src/parameterizations/lateral/MOM_thickness_diffuse.F90 b/src/parameterizations/lateral/MOM_thickness_diffuse.F90 index 8303d30621..55e4593dc4 100644 --- a/src/parameterizations/lateral/MOM_thickness_diffuse.F90 +++ b/src/parameterizations/lateral/MOM_thickness_diffuse.F90 @@ -36,11 +36,14 @@ module MOM_thickness_diffuse !> Control structure for thickness diffusion type, public :: thickness_diffuse_CS ; private logical :: initialized = .false. !< True if this control structure has been initialized. - real :: Khth !< Background interface depth diffusivity [L2 T-1 ~> m2 s-1] + real :: Khth !< Background isopycnal depth diffusivity [L2 T-1 ~> m2 s-1] real :: Khth_Slope_Cff !< Slope dependence coefficient of Khth [nondim] - real :: max_Khth_CFL !< Maximum value of the diffusive CFL for thickness diffusion + real :: max_Khth_CFL !< Maximum value of the diffusive CFL for thickness diffusion [nondim] real :: Khth_Min !< Minimum value of Khth [L2 T-1 ~> m2 s-1] real :: Khth_Max !< Maximum value of Khth [L2 T-1 ~> m2 s-1], or 0 for no max + real :: Kh_eta_bg !< Background interface height diffusivity [L2 T-1 ~> m2 s-1] + real :: Kh_eta_vel !< Velocity scale that is multiplied by the grid spacing to give + !! the interface height diffusivity [L T-1 ~> m s-1] real :: slope_max !< Slopes steeper than slope_max are limited in some way [Z L-1 ~> nondim]. real :: kappa_smooth !< Vertical diffusivity used to interpolate more !! sensible values of T & S into thin layers [Z2 T-1 ~> m2 s-1]. @@ -52,7 +55,7 @@ module MOM_thickness_diffuse !!

With this PR, answers can change when ADD_LES_VISCOSITY=True and there is a Smagorinsky or Leith Laplacian viscosity and there is a nonzero background. One run-time parameter is no longer logged if LAPLACIAN=false, so there are changes to the MOM_parameter_doc files. All answers in the MOM6-examples test suite are bitwise identical. --- .../lateral/MOM_hor_visc.F90 | 350 +++++++++--------- 1 file changed, 170 insertions(+), 180 deletions(-) diff --git a/src/parameterizations/lateral/MOM_hor_visc.F90 b/src/parameterizations/lateral/MOM_hor_visc.F90 index 78f48975e5..2cc6b99370 100644 --- a/src/parameterizations/lateral/MOM_hor_visc.F90 +++ b/src/parameterizations/lateral/MOM_hor_visc.F90 @@ -273,20 +273,13 @@ subroutine horizontal_viscosity(u, v, h, diffu, diffv, MEKE, VarMix, G, GV, US, FrictWorkIntz, & ! depth integrated energy dissipated by lateral friction [R L2 T-3 ~> W m-2] grad_vort_mag_h, & !

All answers are bitwise identical, but there are new optional arguments for multiple public interfaces. - Added a new conversion factor element, conv, to the field_restart type to specify how a field is to be unscaled before writing, and whose reciprocal is used to scale restart fields as they are read in. - Added the new optional argument conversion to each of the register_restart_field() and register_restart_pair() routines, which is used to specify how each field will be rescaled when it is written to or read from a restart file. The default is the same as setting this to 1. - Added the new optional argument unscaled to fix_restart_scaling() and fix_restart_unit_scaling() to reset the unit conversion factors that will be save to the restart files to 1, consistent with writing out fields without scaling to the restart files. --- src/core/MOM_verticalGrid.F90 | 9 +- src/framework/MOM_restart.F90 | 178 ++++++++++++++++++----------- src/framework/MOM_unit_scaling.F90 | 13 ++- 3 files changed, 133 insertions(+), 67 deletions(-) diff --git a/src/core/MOM_verticalGrid.F90 b/src/core/MOM_verticalGrid.F90 index a340b5f80f..2df65f09aa 100644 --- a/src/core/MOM_verticalGrid.F90 +++ b/src/core/MOM_verticalGrid.F90 @@ -188,10 +188,17 @@ subroutine verticalGridInit( param_file, GV, US ) end subroutine verticalGridInit !> Set the scaling factors for restart files to the scaling factors for this run. -subroutine fix_restart_scaling(GV) +subroutine fix_restart_scaling(GV, unscaled) type(verticalGrid_type), intent(inout) :: GV !< The ocean's vertical grid structure + logical, optional, intent(in) :: unscaled !< If true, set the restart factors as though the + !! model would be unscaled, which is appropriate if the + !! scaling is undone when writing a restart file.

From 7c3f31bd473da8c0a9fef327bf14b0ba56aadc95 Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Mon, 21 Mar 2022 10:32:36 -0400 Subject: [PATCH 0149/1329] +(*)Write unscaled MOM6 restart files Revised the MOM6 code so that the output restart files are always exactly the same as they would be if no dimensional rescaling is applied. The input restart files can still have rescaling, so files written by previous versions of the code still work exactly as before. This does change the output, in the sense that the restart files are unscaled and some units documents in the restart files are corrected, but the solutions themselves are bitwise identical. Also, there are new (non-optional) unit scaling type arguments to several routines. The specific changes in this commit include: - Added conversion factors to all register_restart_field() or register_restart_pair() call for variables that are subject to dimensional rescaling. - Revised the calculation of restart rescaling factors to reflect the rescaling that now occurs directly in the restore_state() call. - Added new US arguments to register_restarts_dyn_split_RK2(), MEKE_alloc_register_restart(), set_visc_register_restarts() - Added a new GV argument to mixedlayer_restrat_register_restarts() - Used the new unscaled argument in calls to fix_restart_scaling() and fix_restart_unit_scaling() - Revised several calls to register_restart_field() to avoid using the variant that uses a var_desc type, eliminating the need for some modules to reference the vardesc type or the routine var_desc(). - Added or corrected unit descriptions to the comments describing a few variables. - Noted a few probably bugs in comments with ###, but did not fix them. --- src/core/MOM.F90 | 55 +++++++--------- src/core/MOM_barotropic.F90 | 26 ++++---- src/core/MOM_dynamics_split_RK2.F90 | 66 +++++++++---------- src/core/MOM_open_boundary.F90 | 64 ++++++++++-------- src/ice_shelf/MOM_ice_shelf.F90 | 24 +++---- src/ice_shelf/MOM_ice_shelf_dynamics.F90 | 27 ++++---- src/ice_shelf/MOM_ice_shelf_initialize.F90 | 49 +++++++------- .../MOM_state_initialization.F90 | 11 ++-- src/ocean_data_assim/MOM_oda_incupd.F90 | 52 +++++++-------- src/parameterizations/lateral/MOM_MEKE.F90 | 65 +++++++++--------- .../lateral/MOM_internal_tides.F90 | 10 ++- .../lateral/MOM_mixed_layer_restrat.F90 | 28 ++++---- .../vertical/MOM_set_viscosity.F90 | 25 +++---- src/tracer/boundary_impulse_tracer.F90 | 6 +- src/user/MOM_controlled_forcing.F90 | 36 +++++----- 15 files changed, 280 insertions(+), 264 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 8f6dab2a1a..5b35c01a42 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -2422,7 +2422,7 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, restart_CSp, & call restart_init(param_file, restart_CSp) call set_restart_fields(GV, US, param_file, CS, restart_CSp) if (CS%split) then - call register_restarts_dyn_split_RK2(HI, GV, param_file, & + call register_restarts_dyn_split_RK2(HI, GV, US, param_file, & CS%dyn_split_RK2_CSp, restart_CSp, CS%uh, CS%vh) elseif (CS%use_RK2) then call register_restarts_dyn_unsplit_RK2(HI, GV, param_file, & @@ -2437,9 +2437,9 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, restart_CSp, & call call_tracer_register(HI, GV, US, param_file, CS%tracer_flow_CSp, & CS%tracer_Reg, restart_CSp) - call MEKE_alloc_register_restart(HI, param_file, CS%MEKE, restart_CSp) - call set_visc_register_restarts(HI, GV, param_file, CS%visc, restart_CSp) - call mixedlayer_restrat_register_restarts(HI, param_file, & + call MEKE_alloc_register_restart(HI, US, param_file, CS%MEKE, restart_CSp) + call set_visc_register_restarts(HI, GV, US, param_file, CS%visc, restart_CSp) + call mixedlayer_restrat_register_restarts(HI, GV, param_file, & CS%mixedlayer_restrat_CSp, restart_CSp) if (CS%rotate_index .and. associated(OBC_in) .and. use_temperature) then @@ -2468,7 +2468,7 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, restart_CSp, & !

In MOM_ice_shelf_initialize.F90 changes are made to initialize_ice_thickness_from_file() to correct masks at initialization. * Changed indentation * Changes are made to 'calc_shelf_visc()` to make computations of the velocity derivatives rotation-invariant. Changes in `update_ice_shelf()` utilize G%IareaT(:,:) instead of 1/G%areaT(:,:). * Allocate shelf_sfc_mass_flux for dynamic ice shelf configurations * Conditional allocation of ice shelf fluxes and data override call for sfc mass flux * get rid of excessive line length * call data override init for ice shelves * A new subroutine change_thickness_using_precip() changes the ice thickness in response to the atmospheric mass flux * Conditional calls to data_override - Introduces a new flag: DATA_OVERRIDE_SHELF_FLUXES, which if set to True, and ACTIVE_SHELF_DYNAMICS is also True, will enable data_override capability for the surface mass deposition (only avaialble for MOSAIC grid types) * Changes are made to extrapolate_metric() in MOM_grid_initialize.F90 to avoid negative values at the southern boundary of the domain. This is done for grids extending over Antarctica. * Reversed changes in MOM_grid_initialize.F90 to debug a regression test. * Uncommented lines reading the ice velocity from file * Changes to scaling factors and conversions of the 'sfc_mass_flux' parameter * Remove unnecessary diagnostics for ice shelves from MOM_forcing_type * Correct rescaling for data override of ice shelf sfc mass fluxes * Add diagnostic rescaling for ice shelf mass fluxes * Uncommented assignement of 'area_shelf_h(i,j)=G%areaT(i,j)' in MOM_ice_shelf_initialize.F90 and modified the four halo updates in MOM_ice_shelf.F90.

Many instances where character strings are set to length INPUT_STR_LENGTH are replaced by param_file_type%max_line_len. This commit partially addresses MOM6 issue #75. All answers and output are bitwise identical in cases that worked previously, but there is a new element in the publicly visible param_file_type, and some cases where there had previously been errors due to very long input specification may now work. --- src/framework/MOM_file_parser.F90 | 107 +++++++++++++++++++++++++----- 1 file changed, 89 insertions(+), 18 deletions(-) diff --git a/src/framework/MOM_file_parser.F90 b/src/framework/MOM_file_parser.F90 index 3ad551496f..ed86e77bea 100644 --- a/src/framework/MOM_file_parser.F90 +++ b/src/framework/MOM_file_parser.F90 @@ -69,6 +69,9 @@ module MOM_file_parser logical :: log_to_stdout = log_to_stdout_default !< If true, all log !! messages are also sent to stdout. logical :: log_open = .false. !< True if the log file has been opened. + integer :: max_line_len = 4 !< The maximum number of characters in the lines + !! in any of the files in this param_file_type after + !! any continued lines have been combined. integer :: stdout !< The unit number from stdout(). integer :: stdlog !< The unit number from stdlog(). character(len=240) :: doc_file !< A file where all run-time parameters, their @@ -129,6 +132,7 @@ subroutine open_param_file(filename, CS, checkable, component, doc_file_dir) logical :: file_exists, unit_in_use, Netcdf_file, may_check, reopened_file integer :: ios, iounit, strlen, i character(len=240) :: doc_path + character(len=16) :: sub_string type(parameter_block), pointer :: block => NULL() may_check = .true. ; if (present(checkable)) may_check = checkable @@ -196,6 +200,11 @@ subroutine open_param_file(filename, CS, checkable, component, doc_file_dir) " has been opened successfully.", 5) call populate_param_data(iounit, filename, CS%param_data(i)) + !

Some message strings were also changed to be allocatable, while others have sizes that are set using param_file_type%max_line_len.

A partial interface to the POSIX system calls is included as part of the implementation of this feature. An internal global logical flag, `ignore_fatal` is added to the `MOM_error_handler` module which controls the behavior of `FATAL` errors. If true, then `FATAL` errors trigger a signal (here `SIGUSR1`) which call a handler which restores the program to the earlier state. This change allows us to test `FATAL` errors at runtime without stopping program execution, so that we can cycle through multiple errors. This feature is toggled with two new functions, `disable_fatal_errors()` and `enable_fatal_errors()`. This is implemented in part using POSIX system calls from the C standard library (libc), using the C interoperability layer. Details which are unspecified by the POSIX standard, such as the definitions of signals or the datatype size, are defined in a header (`posix.h`) which can be optionally configured at compile-time. The header defaults to use typical Linux POSIX values, and may be configured by autoconf for more exotic platforms in a later patch. The previous state is set and restored by the `setjmp`/`longjmp` (or `sigsetjmp`/`siglongjmp`) functions. Although these functions behave as expected on all tested platforms, a code which uses these functions is not standards-conforming. If issues arise in the future, error handling may not be available on those platforms, and compile-time configuration may be required to disable these features. No existing code is using these features, but are expected to be part of a future patch.

Rather the root cause of the issues is some of these arguments are optional and are being passed to FMS even thought they are not present! Then they are trapped in FMS diag_manager inside a SELECT TYPE statement and the compiler is not smart enough to know that they are absent and bombs.  --- .../infra/FMS1/MOM_diag_manager_infra.F90 | 43 ++++++++++++++++--- .../infra/FMS2/MOM_diag_manager_infra.F90 | 43 ++++++++++++++++--- 2 files changed, 74 insertions(+), 12 deletions(-) diff --git a/config_src/infra/FMS1/MOM_diag_manager_infra.F90 b/config_src/infra/FMS1/MOM_diag_manager_infra.F90 index 18c80cf24c..c588628cbc 100644 --- a/config_src/infra/FMS1/MOM_diag_manager_infra.F90 +++ b/config_src/infra/FMS1/MOM_diag_manager_infra.F90 @@ -236,9 +236,15 @@ integer function register_static_field_infra(module_name, field_name, axes, long integer, optional, intent(in) :: area !< Diagnostic ID of the field containing the area attribute integer, optional, intent(in) :: volume !< Diagnostic ID of the field containing the volume attribute - register_static_field_infra = register_static_field_fms(module_name, field_name, axes, long_name, units,& - & missing_value, range, mask_variant, standard_name, dynamic=.false.,do_not_log=do_not_log, & + if(present(missing_value) .or. present(range)) then + register_static_field_infra = register_static_field_fms(module_name, field_name, axes, long_name, units,& + & missing_value, range, mask_variant=mask_variant, standard_name=standard_name, dynamic=.false.,& + do_not_log=do_not_log, interp_method=interp_method,tile_count=tile_count, area=area, volume=volume) + else + register_static_field_infra = register_static_field_fms(module_name, field_name, axes, long_name, units,& + & mask_variant=mask_variant, standard_name=standard_name, dynamic=.false.,do_not_log=do_not_log, & interp_method=interp_method,tile_count=tile_count, area=area, volume=volume) + endif end function register_static_field_infra !> Returns true if the argument data are successfully passed to a diagnostic manager @@ -267,7 +273,20 @@ logical function send_data_infra_1d(diag_field_id, field, is_in, ie_in, time, ma character(len=*), optional, intent(out) :: err_msg !< A log indicating the status of the post upon !!

This form uses the JHL mixing coefficient when the ePBL coefficient is +small. + +This approach is reasonable when the wind-driven mixing dominates, since both JHL and ePBL +give a similar solution when deployed optimally. One weakness of this approach is the +tropical region, where the shear-driven ePBL \f$m_\ast\f$ coefficient is not formulated. +The JHL parameterization is skillful to simulate this mixing, but does not include the +contribution of convection. The convective portion of \f$K_{ePBL}\f$ should be combined +with \f$K_{JHL}\f$ in the equatorial region when shear and convection occur together. +Future research is warranted. + +Finally, one should note that the mixing coefficient here (\f$K\f$) is used for both +diffusivity and viscosity, implying a turbulent Prandtl number of 1.0. + +\subsection subsection_Langmuir Langmuir circulation + +While only briefly alluded to in \cite reichl2018, the MOM6 code implementing ePBL does +support the option to add a Langmuir parameterization. There are in fact two options, both +adjusting \f$m_\ast\f$. */ From 4a91628395dd97182ff03563adaf55463315e375 Mon Sep 17 00:00:00 2001 From: Kate Hedstrom Date: Wed, 6 Oct 2021 14:53:52 -0800 Subject: [PATCH 0203/1329] Undoing some patches from others --- src/core/MOM_barotropic.F90 | 32 +++------------------ src/framework/MOM_horizontal_regridding.F90 | 9 ------ 2 files changed, 4 insertions(+), 37 deletions(-) diff --git a/src/core/MOM_barotropic.F90 b/src/core/MOM_barotropic.F90 index 3b5c812ba1..7d9c4facb2 100644 --- a/src/core/MOM_barotropic.F90 +++ b/src/core/MOM_barotropic.F90 @@ -225,10 +225,7 @@ module MOM_barotropic !! pressure [nondim].

None are serious, and none are likely to resolve any outstanding issues. The main benefit is that it allows us to apply the `-pedantic` flag into our testing, which can help to detect future issues. The issues which have been fixed are described below. * The `nX` edit descriptor must include the number of forward steps. The implicit single step (`1x == x`) is a compiler extension. * The no-advance line record write token `$` is a compiler extension which is not described in the standard. Non-advancement is handled with the `advance='no'` argument. * Edit descriptors in format statements must be separated by commas, even though many compilers will ignore missing commas if there is no ambiguity. * When line continuation tokens are applied to strings, they must appear at both the end of the first line and the beginning of the subsequent line. Most compilers do not require this second starting token. * In function descriptions, if a variable used in the declaration of another variable, such as an array index, then it must be declared before any other variables refers to it. For example, this is invalid: ``` function foo(i0, x) real :: x(i0:) integer :: i0 ``` and `i0` must be declared before `x`. --- .../GFDL_ocean_BGC/FMS_coupler_util.F90 | 4 +- .../GFDL_ocean_BGC/generic_tracer.F90 | 4 +- src/ALE/MOM_remapping.F90 | 26 +- src/core/MOM.F90 | 6 +- src/core/MOM_forcing_type.F90 | 4 +- src/core/MOM_open_boundary.F90 | 2 +- src/diagnostics/MOM_PointAccel.F90 | 466 +++++++++--------- src/diagnostics/MOM_debugging.F90 | 6 +- src/diagnostics/MOM_sum_output.F90 | 6 +- src/framework/MOM_checksums.F90 | 2 +- src/framework/MOM_diag_mediator.F90 | 4 +- src/framework/MOM_diag_vkernels.F90 | 8 +- src/framework/MOM_domains.F90 | 2 +- src/framework/MOM_horizontal_regridding.F90 | 2 +- src/framework/MOM_write_cputime.F90 | 2 +- src/ice_shelf/MOM_ice_shelf_dynamics.F90 | 2 +- .../vertical/MOM_ALE_sponge.F90 | 2 +- src/tracer/MOM_lateral_boundary_diffusion.F90 | 6 +- src/tracer/MOM_neutral_diffusion.F90 | 24 +- src/tracer/MOM_tracer_advect.F90 | 4 +- 20 files changed, 291 insertions(+), 291 deletions(-) diff --git a/config_src/external/GFDL_ocean_BGC/FMS_coupler_util.F90 b/config_src/external/GFDL_ocean_BGC/FMS_coupler_util.F90 index e50f2ccf0b..b7ee7de684 100644 --- a/config_src/external/GFDL_ocean_BGC/FMS_coupler_util.F90 +++ b/config_src/external/GFDL_ocean_BGC/FMS_coupler_util.F90 @@ -11,9 +11,9 @@ module FMS_coupler_util !> Get element and index of a boundary condition subroutine extract_coupler_values(BC_struc, BC_index, BC_element, array_out, ilb, jlb, & is, ie, js, je, conversion) -

This is problematic for the sequence 0x8000 0000, because it must be set with a value of -2**31. In 4-byte integers, this is strictly not representable in Fortran, which requires symmetric signed domains for its variables. Since the upper bound is 2**31 - 1, the lower bound must be -2**31 + 1, which is larger than -2**31. Any value assigned to the 0x80000000 bit sequence is considered a noncompliant compiler extension. The current implementation seems to resolve this by using a kind=8 value (itself problematic, since 8-byte is not assured), but it still requires assigning this value to a 4-byte integer which cannot (strictly) represent the value. This patch averts the whole issue by explicitly setting the bits, and makes no reference to its integer value. It leaves the compiler to decide its interpretation. And since the variable is only used in bit operations, there is no ambiguity in behavior. Note that GCC 9 does not support BOZ conversion from z'80000000' to int, since it still expects BOZ literals to be within the bounds. This is why we use ibset() in place of a literal.

There are two new files, MOM_hybgen_regrid.F90 and MOM_hybgen_unmix.F90, which in turn add 15 new runtime parameters (with names like HYBGEN_...) to control the hybgen code. This new regridding option is specified via REGRIDDING_COORDINATE_MODE="HYBGEN", and this new option is listed in the MOM_parameter_doc files for cases that have USE_REGRIDDING=True. There is also a new publicly visible parameter, REGRIDDING_HYBGEN, in regrid_consts.F90. In addition, the new routine regridding_preadjust_reqs is provided in MOM_regridding to specify whether convective adjustment or hybgen_unmixing should be done before regridding. This is used along with the optional argument conv_adjust to regridding_main to move these pre-adjustment steps out of regridding_main. The unused routine ALE_build_grid was eliminated, and comments were added describing a few undocumented internal real variables. All answers are bitwise identical, but there are several new public interfaces and there will be new lines in the comments in some MOM_parameter_doc files. --- src/ALE/MOM_ALE.F90 | 103 +- src/ALE/MOM_hybgen_regrid.F90 | 983 ++++++++++++++++++ src/ALE/MOM_hybgen_unmix.F90 | 502 +++++++++ src/ALE/MOM_regridding.F90 | 97 +- src/ALE/regrid_consts.F90 | 5 + .../MOM_state_initialization.F90 | 39 +- 6 files changed, 1646 insertions(+), 83 deletions(-) create mode 100644 src/ALE/MOM_hybgen_regrid.F90 create mode 100644 src/ALE/MOM_hybgen_unmix.F90 diff --git a/src/ALE/MOM_ALE.F90 b/src/ALE/MOM_ALE.F90 index fa195d57eb..97303aa100 100644 --- a/src/ALE/MOM_ALE.F90 +++ b/src/ALE/MOM_ALE.F90 @@ -20,6 +20,8 @@ module MOM_ALE use MOM_error_handler, only : MOM_error, FATAL, WARNING use MOM_error_handler, only : callTree_showQuery use MOM_error_handler, only : callTree_enter, callTree_leave, callTree_waypoint +use MOM_hybgen_unmix, only : hybgen_unmix, init_hybgen_unmix, end_hybgen_unmix, hybgen_unmix_CS +use MOM_hybgen_regrid, only : hybgen_regrid_CS use MOM_file_parser, only : get_param, param_file_type, log_param use MOM_interface_heights,only : find_eta use MOM_open_boundary, only : ocean_OBC_type, OBC_DIRECTION_E, OBC_DIRECTION_W @@ -27,6 +29,7 @@ module MOM_ALE use MOM_regridding, only : initialize_regridding, regridding_main, end_regridding use MOM_regridding, only : uniformResolution use MOM_regridding, only : inflate_vanished_layers_old +use MOM_regridding, only : regridding_preadjust_reqs, convective_adjustment use MOM_regridding, only : set_target_densities_from_GV, set_target_densities use MOM_regridding, only : regriddingCoordinateModeDoc, DEFAULT_COORDINATE_MODE use MOM_regridding, only : regriddingInterpSchemeDoc, regriddingDefaultInterpScheme @@ -73,6 +76,11 @@ module MOM_ALE type(remapping_CS) :: remapCS !< Remapping parameters and work arrays type(remapping_CS) :: vel_remapCS !< Remapping parameters for velocities and work arrays + type(hybgen_unmix_CS), pointer :: hybgen_unmixCS => NULL() !< Parameters for hybgen remapping + + logical :: use_hybgen_unmix !< If true, use the hybgen unmixing code before regridding + logical :: do_conv_adj !< If true, do convective adjustment before regridding + integer :: nk !< Used only for queries, not directly by this module real :: BBL_h_vel_mask !< The thickness of a bottom boundary layer within which velocities in !! thin layers are zeroed out after remapping, following practice with @@ -119,7 +127,6 @@ module MOM_ALE public ALE_main_offline public ALE_offline_inputs public ALE_offline_tracer_final -public ALE_build_grid public ALE_regrid_accelerated public ALE_remap_scalar public ALE_PLM_edge_values @@ -165,6 +172,8 @@ subroutine ALE_init( param_file, GV, US, max_depth, CS) logical :: force_bounds_in_subcell logical :: local_logical logical :: remap_boundary_extrap + type(hybgen_regrid_CS), pointer :: hybgen_regridCS => NULL() !

Specifically - Eliminated global_field_sum() from MOM_domains, as it is no longer used anywhere in the MOM6 code or drivers. At the config_src/infra level, the pass-through calls to mpp_global_sum are commented out in case there are other versions of the MOM6 code that still use global_field_sum. - Added explicit interfaces to horizontal_interp_init() and time_interp_extern_init() in the config_src/infra rather that leaving them as undocumented pass-throughs to the FMS code. - Added the explicit subroutine stdout_if_root() to MOM_io.F90 to replace an undocumented pass-through to the FMS stdout function. - Added comments describing the publicly visible encoding parameters ind_flux, ind_alpha, and ind_csurf that are a part of the coupler_types module. - Removed the unnecessary or commented-out public declarations for post_data_1d_k, vert_fill_TS, and legacy_diabatic. All answers are bitwise identical, but there are some minor changes to the names of subroutines offered at the config_src/infra level to permit the documentation of these interfaces without running afoul of some bugs with certain versions of the gnu compiler. --- .../drivers/mct_cap/mom_surface_forcing_mct.F90 | 1 - .../nuopc_cap/mom_surface_forcing_nuopc.F90 | 1 - config_src/infra/FMS1/MOM_domain_infra.F90 | 6 +++--- config_src/infra/FMS1/MOM_interp_infra.F90 | 14 ++++++++++++-- config_src/infra/FMS2/MOM_domain_infra.F90 | 6 +++--- config_src/infra/FMS2/MOM_interp_infra.F90 | 15 ++++++++++++--- src/framework/MOM_coupler_types.F90 | 4 +++- src/framework/MOM_diag_mediator.F90 | 1 - src/framework/MOM_domains.F90 | 7 ++----- src/framework/MOM_horizontal_regridding.F90 | 9 +++++---- src/framework/MOM_interpolate.F90 | 6 +++--- src/framework/MOM_io.F90 | 6 +++++- .../lateral/MOM_thickness_diffuse.F90 | 1 - .../vertical/MOM_diabatic_driver.F90 | 1 - 14 files changed, 48 insertions(+), 30 deletions(-) diff --git a/config_src/drivers/mct_cap/mom_surface_forcing_mct.F90 b/config_src/drivers/mct_cap/mom_surface_forcing_mct.F90 index a8a3ea0c69..ebb63865b7 100644 --- a/config_src/drivers/mct_cap/mom_surface_forcing_mct.F90 +++ b/config_src/drivers/mct_cap/mom_surface_forcing_mct.F90 @@ -9,7 +9,6 @@ module MOM_surface_forcing_mct use MOM_diag_mediator, only : diag_ctrl use MOM_diag_mediator, only : safe_alloc_ptr, time_type use MOM_domains, only : pass_vector, pass_var, fill_symmetric_edges -use MOM_domains, only : global_field_sum, BITWISE_EXACT_SUM use MOM_domains, only : AGRID, BGRID_NE, CGRID_NE, To_All use MOM_domains, only : To_North, To_East, Omit_Corners use MOM_error_handler, only : MOM_error, WARNING, FATAL, is_root_pe, MOM_mesg diff --git a/config_src/drivers/nuopc_cap/mom_surface_forcing_nuopc.F90 b/config_src/drivers/nuopc_cap/mom_surface_forcing_nuopc.F90 index d04ecf10e4..3c03009d43 100644 --- a/config_src/drivers/nuopc_cap/mom_surface_forcing_nuopc.F90 +++ b/config_src/drivers/nuopc_cap/mom_surface_forcing_nuopc.F90 @@ -10,7 +10,6 @@ module MOM_surface_forcing_nuopc use MOM_diag_mediator, only : diag_ctrl use MOM_diag_mediator, only : safe_alloc_ptr, time_type use MOM_domains, only : pass_vector, pass_var, fill_symmetric_edges -use MOM_domains, only : global_field_sum, BITWISE_EXACT_SUM use MOM_domains, only : AGRID, BGRID_NE, CGRID_NE, To_All use MOM_domains, only : To_North, To_East, Omit_Corners use MOM_error_handler, only : MOM_error, WARNING, FATAL, is_root_pe, MOM_mesg diff --git a/config_src/infra/FMS1/MOM_domain_infra.F90 b/config_src/infra/FMS1/MOM_domain_infra.F90 index 7eff4597f3..f28c36b9d2 100644 --- a/config_src/infra/FMS1/MOM_domain_infra.F90 +++ b/config_src/infra/FMS1/MOM_domain_infra.F90 @@ -27,7 +27,7 @@ module MOM_domain_infra use fms_affinity_mod, only : fms_affinity_init, fms_affinity_set, fms_affinity_get !

Specifically, this allows the code to be compiled with GCC using the -std=f2018 flag. None of these changes impact GFDL testing, since all extensions were supported by GNU, Intel, and PGI, but at least offer some greater assurance that the code will compile and behave more predicably on as-yet untested platforms. The specific changes are outlined below: * `loc() == 0` tests have been replaced with `associated()` where appropriate. (If field is not a pointer then it was removed, since using loc() was already a very bad idea.) * the `dfloat()` type conversion was replaced with `real()`.

In FMS1, `field_sizes` would always expect a `sizes` array of at least size 4, and in the format of (nx, ny, nz, nt), and would lean on netCDF attributes like `cartesian_axes` when assigning the values. FMS2 lacks similar functionality, due its more general approach. Previously, this was emulated in a way favorable to certain situations, but raised issues in others. This patch attempts to resolve the issue by using the `categorize_axes()` function's ability to identify axes, either by attributes, presumed names, or the `unlimited` property. --- config_src/infra/FMS2/MOM_io_infra.F90 | 66 ++++++++++++++++++++++---- 1 file changed, 56 insertions(+), 10 deletions(-) diff --git a/config_src/infra/FMS2/MOM_io_infra.F90 b/config_src/infra/FMS2/MOM_io_infra.F90 index 16b7e45bc6..eb616dffa3 100644 --- a/config_src/infra/FMS2/MOM_io_infra.F90 +++ b/config_src/infra/FMS2/MOM_io_infra.F90 @@ -609,11 +609,14 @@ subroutine get_field_size(filename, fieldname, sizes, field_found, no_domain) !! names with an appended tile number !

In one case, a variable was conditionally used within a preprocessor `#ifdef __DO_SAFETY_CHECKS__` block. This patch moves the declaration into another `#ifdef` block, but perhaps it is preferable to remove the block. Certain documentation variables such as `mdl`, which typically contain the function name, have been removed if unused. The strongest motivation for this patch is to allow us to enable the `-Wall` flag, which includes unused variables, and will strengthen our ability to detect potential errors in the codebase. --- .../solo_driver/MESO_surface_forcing.F90 | 2 -

This is done via optional argument (hevap); * Apply all modifications needed to include a new field in the flux type (heat_content_evap): rotate_array, deallocate, fluxes_accumulate, hchksum, and new diagnostics; * Modify forcing_diagnostics so that diagnostics are properly computed whether enthalpy terms are provided via coupler or computed by MOM6. This is done by introducing a logical variable mom_enthalpy (default = true, meaning dianostics are computed in the default way, using heat_content_massout). When then optional argument (enthalpy) is present and true, mom_enthalpy = false. In this case, diagnositcs are computed using heat_content_evap instead of heat_content_massout. * Deletes all entries associated with heat_content_icemelt. The enthalpy associated with the mass from sea ice formation/melting is already accounted for in field seaice_melt_heat. A note explaining this is also added. Subroutine extractFluxes1d: * When enthalpy terms are computed by MOM6, their contribution to the heat budget is accounted for in subroutine applyBoundaryFluxesInOut. On the other hand, when enthalpy terms are provided via coupler, they are included in net_heat in this subroutine; * By default the heat content from mass entering and leaving the ocean (enthalpy) is diagnosed in this subroutine. When heat_content_evap is associated, the enthalpy terms are provided via coupler and, therefore, they do not need to be computed again. A logical variable (do_enthalpy, deault = true) is introduced for this purposes.

Also revised the comments describing the arguments to a number of the equation of state routines to eliminate confusing options and clearly indicate the units of each input and output variable. As a part of this change, the units of the rho_ref argument to calculate_stanley_density_1d were changed from [kg m-3] to [R ~> kg m-3] to match the equivalent routine calculate_density_1d(). Because this does not appear to have been used previously, this should not be a problem, and answers will not change unless a dimensional consistency test is underway. All answers are bitwise identical, but there is one minor change to the rescaled units of one apparently unused optional argument. --- src/core/MOM_density_integrals.F90 | 253 ++++++++--------------------- src/equation_of_state/MOM_EOS.F90 | 119 +++++++------- 2 files changed, 129 insertions(+), 243 deletions(-) diff --git a/src/core/MOM_density_integrals.F90 b/src/core/MOM_density_integrals.F90 index 5ef04ad280..cfb61e897b 100644 --- a/src/core/MOM_density_integrals.F90 +++ b/src/core/MOM_density_integrals.F90 @@ -140,14 +140,12 @@ subroutine int_density_dz_generic_pcm(T, S, z_t, z_b, rho_ref, rho_0, G_e, HI, & !

All answers in test cases are bitwise identical. - Added calculate_TFreeze_1d to the overloaded interface calculate_TFreeze, with dimensional rescaling of its arguments taken from its EOS_type argument and an optional two-element domain, rather than two mandatory integer arguments used with calculate_TFreeze_array. The older interface is also retained within the overloaded interface to calculate_TFreeze. - Modified calculate_density_scalar and calculate_stanley_density_scalar to use units of [R ~> kg m-3] for its rho_ref optional argument, following the pattern from calculate_density_1d. These arguments were not previously used. - Renamed the internally visible routine calculate_density_second_derivs_array to calculate_density_second_derivs_1d and changed its argument list to take an optional two-element domain, rather than two mandatory integer arguments, to follow the pattern set by calculate_density_derivs_1d. Because this routine was only being called in two places the older interface is not being preserved in the overloaded interface calculate_density_second_derivs. - Renamed the internally visible routine calculate_compress_array to calculate_compress_1d and changed its argument list to take an optional two-element domain, rather than two mandatory integer arguments, to follow the pattern set by calculate_density_derivs_1d. Because this routine was only being called in one place the older interface is not being preserved in the overloaded interface calculate_compress. - Eliminated some unnecessary local variables (mostly p_scale) for brevity and code clarity. - Modified two calls to calculate_density_second_derivs in thickness_diffuse_full to use its revised interface. - Modified one call to calculate_compress in build_slight_column to use its revised interface. --- src/ALE/coord_slight.F90 | 2 +- src/equation_of_state/MOM_EOS.F90 | 258 ++++++++++-------- .../lateral/MOM_thickness_diffuse.F90 | 6 +- 3 files changed, 148 insertions(+), 118 deletions(-) diff --git a/src/ALE/coord_slight.F90 b/src/ALE/coord_slight.F90 index 66c78d7c7a..6c2432d50d 100644 --- a/src/ALE/coord_slight.F90 +++ b/src/ALE/coord_slight.F90 @@ -375,7 +375,7 @@ subroutine build_slight_column(CS, eqn_of_state, H_to_pres, H_subroundoff, & call calculate_density_derivs(T_int, S_int, p_R, drhoR_dT, drhoR_dS, & eqn_of_state, (/2,nz/) ) if (CS%compressibility_fraction > 0.0) then - call calculate_compress(T_int, S_int, p_R(:), rho_tmp, drho_dp, 2, nz-1, eqn_of_state) + call calculate_compress(T_int, S_int, p_R(:), rho_tmp, drho_dp, eqn_of_state, (/2,nz/)) else do K=2,nz ; drho_dp(K) = 0.0 ; enddo endif diff --git a/src/equation_of_state/MOM_EOS.F90 b/src/equation_of_state/MOM_EOS.F90 index a13fd7e2b4..7a70d7f1bd 100644 --- a/src/equation_of_state/MOM_EOS.F90 +++ b/src/equation_of_state/MOM_EOS.F90 @@ -89,17 +89,17 @@ module MOM_EOS !> Calculates the second derivatives of density with various combinations of temperature, !! salinity, and pressure from T, S and P interface calculate_density_second_derivs - module procedure calculate_density_second_derivs_scalar, calculate_density_second_derivs_array + module procedure calculate_density_second_derivs_scalar, calculate_density_second_derivs_1d end interface calculate_density_second_derivs !> Calculates the freezing point of sea water from T, S and P interface calculate_TFreeze - module procedure calculate_TFreeze_scalar, calculate_TFreeze_array + module procedure calculate_TFreeze_scalar, calculate_TFreeze_1d, calculate_TFreeze_array end interface calculate_TFreeze !> Calculates the compressibility of water from T, S, and P interface calculate_compress - module procedure calculate_compress_scalar, calculate_compress_array + module procedure calculate_compress_scalar, calculate_compress_1d end interface calculate_compress !> A control structure for the equation of state @@ -166,34 +166,28 @@ subroutine calculate_density_scalar(T, S, pressure, rho, EOS, rho_ref, scale) real, intent(in) :: pressure !< Pressure [R L2 T-2 ~> Pa] real, intent(out) :: rho !< Density (in-situ if pressure is local) [R ~> kg m-3] type(EOS_type), intent(in) :: EOS !< Equation of state structure - real, optional, intent(in) :: rho_ref !< A reference density [kg m-3] + real, optional, intent(in) :: rho_ref !< A reference density [R ~> kg m-3] real, optional, intent(in) :: scale !< A multiplicative factor by which to scale output density in !! combination with scaling given by US [various] - real :: rho_scale !

Also added new optional arguments to int_density_dz_wright and int_spec_vol_dp_wright to handle rescaling temperature and salinity. There are also many places in MOM_EOS.F90 where comments are altered to reflect the new rescaled units. However, for now these new rescaling factors are hard-coded to 1, so there is no new rescaling yet, and all answers are bitwise identical.

With this change there are 4 new elements in the transparent unit_scale_type, and these are widely used in the code. In addition, ### other files were added that had checksum calls or diagnostics rescaled by these new factors, and where comments were changed, but were otherwise unaltered as a result of the new dimensional rescaling. There will be another commit very shortly that completes the changes and leads to fully functional dimensional rescaling for temperatures and salinities, but these will involve more extensive code or interface changes, but this commit will be useful for any possible git-bisection of any potential changes that do not involve dimensional rescaling.

There are new unit_scale_type arguments to several publicly visible interfaces, mostly related to temperature initialization. There is also a new optional argument, conc_scale to the register_tracer calls to specify the conversion that should be done to tracer concentrations during output. Additionally, there are new entries in the incorrect units on some runtime parameters for user code were corrected in the MOM_parameter_doc files for some test cases. All answers are bitwise identical in the MOM6 regression suite, including when the temperature and salinity rescaling are enabled. --- src/core/MOM.F90 | 99 ++++----- src/core/MOM_forcing_type.F90 | 68 +++---- src/core/MOM_open_boundary.F90 | 115 +++++++---- src/core/MOM_variables.F90 | 33 ++- src/diagnostics/MOM_sum_output.F90 | 14 +- src/equation_of_state/MOM_EOS.F90 | 8 +- src/ice_shelf/MOM_ice_shelf.F90 | 14 +- .../MOM_coord_initialization.F90 | 42 ++-- .../MOM_state_initialization.F90 | 189 +++++++++--------- src/ocean_data_assim/MOM_oda_driver.F90 | 44 ++-- .../vertical/MOM_bulk_mixed_layer.F90 | 122 +++++------ .../vertical/MOM_geothermal.F90 | 42 ++-- .../vertical/MOM_opacity.F90 | 28 +-- src/tracer/MOM_offline_aux.F90 | 16 +- src/tracer/MOM_offline_main.F90 | 26 +-- src/tracer/MOM_tracer_Z_init.F90 | 92 +++++---- src/tracer/MOM_tracer_flow_control.F90 | 2 +- src/tracer/MOM_tracer_registry.F90 | 49 +++-- src/tracer/oil_tracer.F90 | 3 +- src/tracer/pseudo_salt_tracer.F90 | 11 +- src/user/DOME2d_initialization.F90 | 59 +++--- src/user/DOME_initialization.F90 | 18 +- src/user/ISOMIP_initialization.F90 | 127 +++++++----- src/user/RGC_initialization.F90 | 8 +- src/user/Rossby_front_2d_initialization.F90 | 15 +- src/user/SCM_CVMix_tests.F90 | 32 +-- src/user/adjustment_initialization.F90 | 64 +++--- src/user/baroclinic_zone_initialization.F90 | 46 +++-- src/user/benchmark_initialization.F90 | 32 +-- src/user/dense_water_initialization.F90 | 25 +-- src/user/dumbbell_initialization.F90 | 32 +-- src/user/seamount_initialization.F90 | 29 ++- src/user/sloshing_initialization.F90 | 23 ++- 33 files changed, 829 insertions(+), 698 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 56e661f678..92434c0039 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -181,7 +181,7 @@ module MOM type, public :: MOM_control_struct ; private real ALLOCABLE_, dimension(NIMEM_,NJMEM_,NKMEM_) :: & h, & !< layer thickness [H ~> m or kg m-2] - T, & !< potential temperature [degC] + T, & !< potential temperature [C ~> degC] S !< salinity [ppt] real ALLOCABLE_, dimension(NIMEMB_PTR_,NJMEM_,NKMEM_) :: & u, & !< zonal velocity component [L T-1 ~> m s-1] @@ -1231,12 +1231,12 @@ subroutine step_MOM_tracer_dyn(CS, G, GV, US, h, Time_local) call hchksum(h,"Pre-advection h", G%HI, haloshift=1, scale=GV%H_to_m) call uvchksum("Pre-advection uhtr", CS%uhtr, CS%vhtr, G%HI, & haloshift=0, scale=GV%H_to_m*US%L_to_m**2) - if (associated(CS%tv%T)) call hchksum(CS%tv%T, "Pre-advection T", G%HI, haloshift=1) - if (associated(CS%tv%S)) call hchksum(CS%tv%S, "Pre-advection S", G%HI, haloshift=1) + if (associated(CS%tv%T)) call hchksum(CS%tv%T, "Pre-advection T", G%HI, haloshift=1, scale=US%C_to_degC) + if (associated(CS%tv%S)) call hchksum(CS%tv%S, "Pre-advection S", G%HI, haloshift=1, scale=US%S_to_ppt) if (associated(CS%tv%frazil)) call hchksum(CS%tv%frazil, "Pre-advection frazil", G%HI, haloshift=0, & scale=US%Q_to_J_kg*US%RZ_to_kg_m2) if (associated(CS%tv%salt_deficit)) call hchksum(CS%tv%salt_deficit, & - "Pre-advection salt deficit", G%HI, haloshift=0, scale=US%RZ_to_kg_m2) + "Pre-advection salt deficit", G%HI, haloshift=0, scale=US%S_to_ppt*US%RZ_to_kg_m2) ! call MOM_thermo_chksum("Pre-advection ", CS%tv, G, US) call cpu_clock_end(id_clock_other) endif @@ -1415,8 +1415,8 @@ subroutine step_MOM_thermo(CS, G, GV, US, u, v, h, tv, fluxes, dtdia, & if (CS%debug) then call MOM_state_chksum("Pre-ALE ", u, v, h, CS%uh, CS%vh, G, GV, US) - call hchksum(tv%T,"Pre-ALE T", G%HI, haloshift=1) - call hchksum(tv%S,"Pre-ALE S", G%HI, haloshift=1) + call hchksum(tv%T,"Pre-ALE T", G%HI, haloshift=1, scale=US%C_to_degC) + call hchksum(tv%S,"Pre-ALE S", G%HI, haloshift=1, scale=US%S_to_ppt) call check_redundant("Pre-ALE ", u, v, G) endif call cpu_clock_begin(id_clock_ALE) @@ -1442,8 +1442,8 @@ subroutine step_MOM_thermo(CS, G, GV, US, u, v, h, tv, fluxes, dtdia, & if (CS%debug .and.

Also renamed two stochastics-related optional arguments to ePBL_column to better reflect what they do, and corrected a number of spelling errors in comments in the files that were being modified.

Without this change, calls to horiz_interp_and_extrap_tracer with a non-unity conversion factor will exhibit unexpected changes in answers, and may have wildly inappropriate amounts of smoothing of the interpolated values in arrays that are initialized from z-space file. However, the defaults are carefully chosen to avoid changing answers in any cases that do not use rescaling of tracer concentrations. The specific changes include: - Add a new optional argument tr_iter_tol to the horiz_interp_and_extrap_tracer routines to set an appropriate dimensional threshold for when the post-fill smoothing of tracers should be considered to be adequate. - Make the dimensional crit argument to fill_miss_2d non-optional, and fill it with appropriate values in calls from the horiz_interp_and_extrap_tracer routines when tr_iter_tol is not present. There should never be a hard-coded non-zero default for a dimensional variable! - Add a new optional scale argument to myStats - Eliminate the unused and unnecessary smooth logical argument to fill_miss_2d; the same functionality is obtained by setting the num_pass argument to 0. - Added to comments to document the units or unitlessness of the real variables in MOM_horizontal_regridding.F90. - Made minor changes to make the duplicated portions of the two horiz_interp_and_extrap_tracer similar. By default, all answers are bitwise identical, but this corrects a subtle bug with the use of the conversion factor argument in horiz_interp_and_extrap_tracer calls. There are new optional arguments to publicly visible routines. --- src/framework/MOM_horizontal_regridding.F90 | 479 +++++++++++--------- 1 file changed, 259 insertions(+), 220 deletions(-) diff --git a/src/framework/MOM_horizontal_regridding.F90 b/src/framework/MOM_horizontal_regridding.F90 index 5c8035e9b2..ebc59cd288 100644 --- a/src/framework/MOM_horizontal_regridding.F90 +++ b/src/framework/MOM_horizontal_regridding.F90 @@ -35,21 +35,25 @@ module MOM_horizontal_regridding contains !> Write to the terminal some basic statistics about the k-th level of an array -subroutine myStats(array, missing, is, ie, js, je, k, mesg) - real, dimension(:,:), intent(in) :: array !< input array (ND) - real, intent(in) :: missing !< missing value (ND) - integer :: is !< Start index in i - integer :: ie !< End index in i - integer :: js !< Start index in j - integer :: je !< End index in j - integer :: k !< Level to calculate statistics for - character(len=*) :: mesg !< Label to use in message +subroutine myStats(array, missing, is, ie, js, je, k, mesg, scale) + real, dimension(:,:), intent(in) :: array !< input array [A] + real, intent(in) :: missing !< missing value [A] + integer, intent(in) :: is !< Start index in i + integer, intent(in) :: ie !< End index in i + integer, intent(in) :: js !< Start index in j + integer, intent(in) :: je !< End index in j + integer, intent(in) :: k !< Level to calculate statistics for + character(len=*), intent(in) :: mesg !< Label to use in message + real, optional, intent(in) :: scale !< A scaling factor for output. !

From b3c41b10570260c3ede81e4f90b39bd834279950 Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Thu, 12 May 2022 05:50:57 -0400 Subject: [PATCH 0267/1329] +Rescale vars in MOM_temp_salt_initialize_from_Z Works with rescaled temperatures and salinities for the internal calculations in MOM_temp_salt_initialize_from_Z, taking advantage of the recently corrected rescaling capabilities in horiz_interp_and_extrap_tracer. This commit also includes these other closely related changes. - Modified convert_temp_salt_for_TEOS10 to work with rescaled temperature and salinity units - Eliminated unused land_fill argument from determine_temperature - Slightly refactored tracer_z_init_array to avoid needing an extra set of do loop through the 3-d array when a scale argument is present All answers are bitwise identical, but there are changes in the arguments to publicly visible interfaces. --- src/equation_of_state/MOM_EOS.F90 | 8 +- src/framework/MOM_diag_mediator.F90 | 4 +- .../MOM_state_initialization.F90 | 126 ++++++++---------- src/tracer/MOM_tracer_Z_init.F90 | 22 ++- 4 files changed, 72 insertions(+), 88 deletions(-) diff --git a/src/equation_of_state/MOM_EOS.F90 b/src/equation_of_state/MOM_EOS.F90 index 440bd8aa36..a6156d05c0 100644 --- a/src/equation_of_state/MOM_EOS.F90 +++ b/src/equation_of_state/MOM_EOS.F90 @@ -1606,9 +1606,9 @@ subroutine convert_temp_salt_for_TEOS10(T, S, HI, kd, mask_z, EOS) integer, intent(in) :: kd !< The number of layers to work on type(hor_index_type), intent(in) :: HI !< The horizontal index structure real, dimension(HI%isd:HI%ied,HI%jsd:HI%jed,kd), & - intent(inout) :: T !< Potential temperature referenced to the surface [degC] + intent(inout) :: T !< Potential temperature referenced to the surface [C ~> degC] real, dimension(HI%isd:HI%ied,HI%jsd:HI%jed,kd), & - intent(inout) :: S !< Salinity [ppt] + intent(inout) :: S !< Salinity [S ~> ppt] real, dimension(HI%isd:HI%ied,HI%jsd:HI%jed,kd), & intent(in) :: mask_z !< 3d mask regulating which points to convert. type(EOS_type), intent(in) :: EOS !< Equation of state structure @@ -1620,12 +1620,12 @@ subroutine convert_temp_salt_for_TEOS10(T, S, HI, kd, mask_z, EOS) do k=1,kd ; do j=HI%jsc,HI%jec ; do i=HI%isc,HI%iec if (mask_z(i,j,k) >= 1.0) then - S(i,j,k) = gsw_sr_from_sp(S(i,j,k)) + S(i,j,k) = EOS%ppt_to_S*gsw_sr_from_sp(EOS%S_to_ppt*S(i,j,k)) !

These work on arrays of rescaled variables. - Added the new optional argument scale_from_EOS to calculate_TFreeze_scalar, to indicate that this routine should use the unit scaling stored in their EOS_type arguments. - Also corrected some comments throughout MOM_EOS.F90.

The patch includes two new modules (MOM_unit_testing, MOM_file_parser_tests), two new classes (UnitTest, TestSuite), and a new driver (unit_testing). A UnitTest object consists of the following: * The test subroutine * Test name (for reporting) * A flag indicating whether the test should fail (FATAL) * An optional cleanup subroutine The UnitTest objects are gathered into a TestSuite object, which provides a batch job for running all of its tests. The use of these features is demonstrated in a driver, unit_tests, which runs the tests provided in the MOM_file_parser_tests module This patch also includes changes to the ".testing" build system. * The optional FCFLAGS_COVERAGE has been removed from the testing Makefile. Instead, a new "cov" target is optionally built if one wants to check the coverage. It is currently based on "symmetric". * A new "unit" target has been added to run the unit testing driver and report its code coverage. * GitHub Actions has been modified to include the unit driver test. * The gcov output now includes branching (-b), which allows reporting of partial line coverage in some cases. * codecov.io "smart" report searching has been replaced with an explicit setting of the root directory (-R) and *.gcda paths. Other minor changes: * MOM_coms include an infra-level sync function (sync_PEs) as a wrapper to mpp_sync (or others in the future). --- .codecov.yml | 5 +- .github/actions/testing-setup/action.yml | 1 -

All solutions are bitwise identical, but some of the diagnostic output files have minor changes. With these corrections, several output files are now unaltered by internal dimensional rescaling. The specific bug fixes are: - Avoid using a rescaled depth as the vertical coordinate label in z-space output files. Only the coordinate label is impacted, but this bug fix avoids the chance of having silly values for this coordinate. - Rescale the depths back to mks units before taking their checksum for storage in the MOM_sum_output file. With this bug, the depth list file might be unnecessarily recreated with a new run with different scaling, but the file itself is fine. --- src/diagnostics/MOM_sum_output.F90 | 2 +- src/framework/MOM_diag_remap.F90 | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/src/diagnostics/MOM_sum_output.F90 b/src/diagnostics/MOM_sum_output.F90 index 33f3edcfd4..24c1b79bd2 100644 --- a/src/diagnostics/MOM_sum_output.F90 +++ b/src/diagnostics/MOM_sum_output.F90 @@ -1357,7 +1357,7 @@ subroutine get_depth_list_checksums(G, US, depth_chksum, area_chksum) !

From c35da375af674644247adc578f70c51b01d8b16e Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Sat, 7 May 2022 15:51:41 -0400 Subject: [PATCH 0287/1329] +Add user-controlled underflow of tracers Added the ability to do software-controlled underflow of user-specified tiny tracer values to 0. This includes the addition of two new runtime parameters, SALINITY_UNDERFLOW and TEMPERATURE_UNDERFLOW, and the addition of the new optional argument underflow_conc to register_tracer. There is new code that optionally underflows tiny values after tracer advection, all three flavors of tracer diffusion, and after tracer remapping via ALE. By default, underflow is handled via the machine as before, but with appropriately set tiny values of SALINITY_UNDERFLOW and TEMPERATURE_UNDERFLOW, of 1e-30 ppt and 1e-30 degC, all existing test cases pass the dimensional consistency rescaling tests for temperature and salinity, but doing so does change answers slightly for some test cases (detectible in the restart files, but not in the ocean.stats files). By default all answers are bitwise identical, but there are two new runtime parameters. --- src/ALE/MOM_ALE.F90 | 6 ++ src/core/MOM.F90 | 15 +++- src/tracer/MOM_lateral_boundary_diffusion.F90 | 1 + src/tracer/MOM_neutral_diffusion.F90 | 1 + src/tracer/MOM_tracer_advect.F90 | 2 + src/tracer/MOM_tracer_hor_diff.F90 | 2 + src/tracer/MOM_tracer_registry.F90 | 69 +++++++++++-------- 7 files changed, 65 insertions(+), 31 deletions(-) diff --git a/src/ALE/MOM_ALE.F90 b/src/ALE/MOM_ALE.F90 index 810f152e4a..5240061c3f 100644 --- a/src/ALE/MOM_ALE.F90 +++ b/src/ALE/MOM_ALE.F90 @@ -882,6 +882,11 @@ subroutine remap_all_state_vars(CS, G, GV, h_old, h_new, Reg, OBC, & h_neglect, h_neglect_edge) endif + !

However, this term is only allocated if KPP is being used, leading to a segfault if `USE_KPP = False`. This may have been the intended purpose of `Kv_slow`, but its contribution is already added to the shear term before convection is calculated, so convection can't be accounted using `Kv_slow`. To ensure we don't hit a segfault, and that the enhanced viscosity is actually present, we change convection to go into `Kv_shear` in all cases. --- src/parameterizations/vertical/MOM_diabatic_driver.F90 | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) diff --git a/src/parameterizations/vertical/MOM_diabatic_driver.F90 b/src/parameterizations/vertical/MOM_diabatic_driver.F90 index 61c30830a8..831ffa293b 100644 --- a/src/parameterizations/vertical/MOM_diabatic_driver.F90 +++ b/src/parameterizations/vertical/MOM_diabatic_driver.F90 @@ -753,7 +753,7 @@ subroutine diabatic_ALE_legacy(u, v, h, tv, Hml, fluxes, visc, ADp, CDp, dt, Tim !

The Travis CI config was retained in case other groups still preferred to use it. But at this time, no groups appear to be doing so. Also, the presence of this file can trigger runs in older forks which may still keep Travis activated, which generally results in errors due to the greater restrictions imposed by Travis. To keep things running smoothly and avert such problems, this patch simply removes the config file. --- .travis.yml | 86 ----------------------------------------------------- 1 file changed, 86 deletions(-) delete mode 100644 .travis.yml diff --git a/.travis.yml b/.travis.yml deleted file mode 100644 index c34089ddf6..0000000000 --- a/.travis.yml +++ /dev/null @@ -1,86 +0,0 @@ -# This Travis-CI file is for testing the state of the MOM6 source code. -# It does NOT test MOM6 solutions. - -# This is a not a c-language project but we use the same environment. -language: c -dist: bionic - -addons: - apt: - sources: - - ubuntu-toolchain-r-test - packages: - - tcsh pkg-config netcdf-bin libnetcdf-dev libnetcdff-dev gfortran - - mpich libmpich-dev - - graphviz flex bison cmake - - python-numpy python-netcdf4 - - python3 python3-dev python3-venv python3-pip python3-sphinx python3-lxml - - bc - - perl - - texlive-binaries texlive-base bibtool tex-common texlive-bibtex-extra - -# Environment variables -env: - global: - - TIMEFORMAT: "\"Time: %lR (user: %lU, sys: %lS)\"" - - FCFLAGS_DEBUG: "\"-g -O0 -Wextra -Wno-compare-reals -fbacktrace -ffpe-trap=invalid,zero,overflow -fcheck=bounds\"" - - FCFLAGS_REPRO: "\"-g -O2 -fbacktrace\"" - - FCFLAGS_INIT: "\"-finit-real=snan -finit-integer=2147483647 -finit-derived\"" - - FCFLAGS_COVERAGE: "\"--coverage\"" - - DO_REPRO_TESTS: true - -jobs: - include: - - env: JOB="Code compliance" - script: - # Whitespace - - ./.testing/trailer.py -e TEOS10 -l 120 src config_src - # API Documentation - - perl -e 'print "perl version $^V" .

This was trying to encapsulate the commands used in the pipeline so they could also be used at the command line (for emulating the pipeline). However, it required emulating the temporary/transient work-spaces provided by gitlab. Also, the Makefile was impenetrable. New approach: - Create a persistent working space for each pipeline, just as you'd work interactively in a single working directory - Use the same commands in .gitlab-ci.yml as we'd use interactively (these still use the tools/MRS Makefile.build and Makefile.run) - The compute stage of tasks is now a bash script (.gitlab/mom6-ci-run-script.sh) which will work/can be submitted from your working directory - The caching of results from each run (gnu/intel/pgi, symmetric/nonsymmetric/layout/etc) is stored locally in the same working directory so we don't have to look elsewhere for the results - Using the "fetch" strategy allows later stages to startup in mere seconds (previously re-cloning the repo took minutes) This does not shorten the turn around significantly but I believe it is a lot easy to follow and emulate. Todo: - split up the run stage to reduce it from 41+ minutes to ~13 minutes. --- .gitlab-ci.yml | 208 ++++++++++++++++++++++++++-------- .gitlab/mom6-ci-run-script.sh | 129 +++++++++++++++++++++ 2 files changed, 289 insertions(+), 48 deletions(-) create mode 100644 .gitlab/mom6-ci-run-script.sh diff --git a/.gitlab-ci.yml b/.gitlab-ci.yml index c22bfc4144..ba22339753 100644 --- a/.gitlab-ci.yml +++ b/.gitlab-ci.yml @@ -1,86 +1,155 @@ stages: + - setup - builds - run - tests - cleanup +# JOB_DIR points to a persistent working space used for most stages in this pipeline but +# it is unique to this pipeline. +# We use the "fetch" strategy to speed up the startup of stages variables: - CACHE_DIR: "/lustre/f2/scratch/oar.gfdl.ogrp-account/runner/cache/" + JOB_DIR: "/lustre/f2/scratch/oar.gfdl.ogrp-account/runner/builds/$CI_PIPELINE_ID" + GIT_STRATEGY: fetch - -# Merges MOM6 with dev/gfdl.

The addition of this script is the bulk of this commit. Code changes: - when more than one program is encountered the executable is given the name following "program". Since all the programs were named "MOM_main" I have had to change them to provide unique names: - MOM_sum_driver.F90, "program MOM_main" has been changed to "MOM_sum_driver" - solo_driver/MOM_driver.F90, "program MOM_main" has been changed to "MOM6" Script changes: - Makefile.in now has a target "depend" to generate dependencies using makedep - configure.ac no longer checks for list_paths and mkmf - configure.ac now invokes "make depend" in place of mkmf - Added target "unit" to .testing/Makefile to build all programs in config_src/drivers/unit_drivers Ugliness: - I had to add a -f option to makedep to handle FMS non-standard macros - To compile FMS, the dependencies Makefile is passed CPPDEFS in addition to CPPFLAGS. - The first version of makedep was consistent with the standard gmake rules which were sufficient to build MOM6. Adding -f "rule command" allows FMS to be built: makemake -f '$(FC) $(FFLAGS) $(CPPFLAGS) $(CPPDEFS) -c $<' -x libFMS.a ../src - .inc suffix is included when searching for include directories - FMS has includes of .inc files which modify the search path passed to /lib/cpp . - Handling of badly formatted comments when searching for modules - FMS fm_util.F90, that generates fm_util_mod.mod, has some odd strings in a comment on the module declaration line. This was causing wierdness in the script. - Not just Fortran dependencies - makedep needs to also generate rules for C files in order to build FMS Todo: [ ] *A work around is used for TEOS10 (gsw_*) functions that are in separate object files even though accessed via a module (WTFortran!!!) --- .testing/Makefile | 19 +- ac/Makefile.in | 10 +- ac/configure.ac | 43 +--- ac/deps/Makefile | 21 +- ac/deps/Makefile.fms.in | 8 +- ac/deps/configure.fms.ac | 36 +-- ac/makedep | 225 ++++++++++++++++++ config_src/drivers/solo_driver/MOM_driver.F90 | 4 +- .../drivers/unit_drivers/MOM_sum_driver.F90 | 4 +- 9 files changed, 262 insertions(+), 108 deletions(-) create mode 100755 ac/makedep diff --git a/.testing/Makefile b/.testing/Makefile index d9feb25f0b..6e61ec8f39 100644 --- a/.testing/Makefile +++ b/.testing/Makefile @@ -119,10 +119,6 @@ DIMS ?= t l h z q r # Dependencies DEPS = deps -# mkmf, list_paths (GFDL build toolchain) -LIST_PATHS := $(DEPS)/bin/list_paths -MKMF := $(DEPS)/bin/mkmf -

This patch uses the generalized @srcdir@ to support more general autoconf builds. Other minor changes: * The `depend` rule was split into an explicit Makefile.dep rule and a phony rule to support `make depend` * SRC_DIRS shell assignment is replaced with an Autoconf macro. * A "self-generate" rule was added to `Makefile.in`, so that changes to `Makefile.in` do not trigger a full `./configure` run and regeneration of `.config.status`. This could possibly be extended to support `make depend` but let's first see how this one goes. * Autoconf: makedep uses autoconf var conventions This patch changes the makedep script to use autoconf environment variable conventions rather than mkmf ones: * FCFLAGS in place of FFLAGS * DEFS in place of CPPDEFS * LDFLAGS and LIBS rather than just LDFLAGS (NOTE: This differs from Makefile's LDLFLAGS/LDLIBS) This also allowed us to remove the custom build rule in the FMS build. Note that we now use an autoconf-friendly rule, rather than the default Makefile rule (which was arguably for fixed-format Fortran anyway). The description of autoconf->mkmf translation from the Makefile templates has also been removed, since they're no longer relevant. Some other minor changes in this build: * The `make depend` rule was added to the FMS Makefile template. * @srcdir@ is directly passed to FMS makedep, rather than identically re-defining it in a variable. * Testing: Resolve makedep paths This patch resolves some issues relating to finding the path to makedep in both .testing and more generalized autoconf builds. An explicit autoconf test for makedep has been added, with a default path which includes the `ac` directory relative to `deps`. The .testing directory, which does not lie within `ac`, instead modifies the PATH to allow autoconf to find makedep. The absolute path is determined and substituted into the appropriate Makefile.in template. Some redundant operations in .testing/Makefile have been removed, but I suspect there are even more. Much of the structure required to support mkmf and list_paths is probably no longer needed. --- .testing/Makefile | 3 +- ac/Makefile.in | 65 +++++++++++----------------------------- ac/configure.ac | 17 +++++++---- ac/deps/Makefile | 16 ++++------ ac/deps/Makefile.fms.in | 59 ++++++------------------------------ ac/deps/configure.fms.ac | 22 +++++++++----- ac/makedep | 12 ++++---- 7 files changed, 64 insertions(+), 130 deletions(-) diff --git a/.testing/Makefile b/.testing/Makefile index 6e61ec8f39..972c213032 100644 --- a/.testing/Makefile +++ b/.testing/Makefile @@ -324,7 +324,7 @@ $(TARGET_CODEBASE): # FMS # Set up the FMS build environment variables -FMS_ENV = PATH="${PATH}:../../bin" FCFLAGS="$(FCFLAGS_DEBUG)" +FMS_ENV = PATH="${PATH}:$(realpath ../ac)" FCFLAGS="$(FCFLAGS_DEBUG)" # TODO: *.mod dependencies? $(DEPS)/lib/libFMS.a: $(DEPS)/fms/build/libFMS.a @@ -335,7 +335,6 @@ $(DEPS)/fms/build/libFMS.a: $(DEPS)/fms/build/Makefile $(DEPS)/fms/build/Makefile: $(DEPS)/fms/src/configure $(DEPS)/Makefile.fms.in $(FMS_ENV) $(MAKE) -C $(DEPS) fms/build/Makefile - $(MAKE) -C $(DEPS) fms/build/Makefile $(DEPS)/Makefile.fms.in: ../ac/deps/Makefile.fms.in $(DEPS)/Makefile cp $< $(DEPS) diff --git a/ac/Makefile.in b/ac/Makefile.in index 711fab1f6f..2e482ab0c5 100644 --- a/ac/Makefile.in +++ b/ac/Makefile.in @@ -2,65 +2,34 @@ # # Compiler flags are configured by autoconf's configure script. # -# Source code dependencies are configured by mkmf and list_paths, specified in -# the `Makefile.mkmf` file. -# -# mkmf conventions are close, but not identical, to autoconf.

From 8c605fef331c45fc5cdfeb62a46ffa1e9b9c0ab6 Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Wed, 4 May 2022 18:14:53 -0400 Subject: [PATCH 0297/1329] (*)Internal thickness variable unit correction Changed the internal units of several internal thickness variables in ePBL_column and of some temporary diagnostics in MOM_bulk_mixed_layer from [Z] to [H] to reduce the number of rescaling factors that are being applied outside of the conversion factors when diagnostics are registered. All answers and output are bitwise identical in the MOM6-examples test suite, although in some cases where ePBL is used with a non-Boussinesq model, there may be answers at roundoff. I wanted to make this change now before any such models exist. --- .../vertical/MOM_bulk_mixed_layer.F90 | 34 ++++++------- .../vertical/MOM_diapyc_energy_req.F90 | 31 ++++++------ .../vertical/MOM_energetic_PBL.F90 | 50 ++++++++++--------- .../vertical/MOM_kappa_shear.F90 | 4 +- 4 files changed, 61 insertions(+), 58 deletions(-) diff --git a/src/parameterizations/vertical/MOM_bulk_mixed_layer.F90 b/src/parameterizations/vertical/MOM_bulk_mixed_layer.F90 index 5df132a44d..aa0d05ce79 100644 --- a/src/parameterizations/vertical/MOM_bulk_mixed_layer.F90 +++ b/src/parameterizations/vertical/MOM_bulk_mixed_layer.F90 @@ -230,7 +230,7 @@ subroutine bulkmixedlayer(h_3d, u_3d, v_3d, tv, fluxes, dt, ea, eb, G, GV, US, C integer, dimension(SZI_(G),SZK_(GV)) :: & ksort !

This was because of a line that changes the state of data pointed to from within `CS`, but not `CS` itself: CS%restart_field(n)%initialized = .true. The strict interpretation is that `CS` is not modified because `CS%restart_field` is a pointer to memory elsewhere. However, the `intent(in)` indicates to the user/programmer that nothing changes and since all arguments to the functions are `intent(in)` most entities, including the PGI compiler, should be surprised that something changed as a result of a passive "query" function. This strict interpretation allows a devious hidden-change-of-state to occur. - Changing the intent to `intent(inout)` has the consequence that the new intent has to be propagated upwards through the code. And why should a type be `intent(out)` for query functions? - This commit removes offending lines that change the state.

Therefore, the old CI would launch tests of all experiments/configurations concurrently but would cycle through each group of tests (compilers, layout, etc.) sequentially, copying the output and reusing the same work space. Making copies of the work space is slow, and running more concurrent jobs requires more nodes to be available at once, so the "four" has been found to be optimal for gaea and current work load. - We only have six runners (on the six compilation nodes) which limits the pipeline to six jobs at once. Allowing multiple jobs per runner could remove this limitation but would impact the system more. - The restart testing is the slowest section of the run stage (even though for a subset of experiments). Separating restarts out allows more concurrency. Doing restart tests for more experiments and all compilers would be very expensive. --- .gitlab-ci.yml | 273 +++++++++++++++------ .gitlab/mom6-ci-run-gnu-restarts-script.sh | 47 ++++ .gitlab/mom6-ci-run-gnu-script.sh | 71 ++++++ .gitlab/mom6-ci-run-intel-script.sh | 57 +++++ .gitlab/mom6-ci-run-pgi-script.sh | 57 +++++ .gitlab/mom6-ci-run-script.sh | 129 ---------- 6 files changed, 427 insertions(+), 207 deletions(-) create mode 100644 .gitlab/mom6-ci-run-gnu-restarts-script.sh create mode 100644 .gitlab/mom6-ci-run-gnu-script.sh create mode 100644 .gitlab/mom6-ci-run-intel-script.sh create mode 100644 .gitlab/mom6-ci-run-pgi-script.sh delete mode 100644 .gitlab/mom6-ci-run-script.sh diff --git a/.gitlab-ci.yml b/.gitlab-ci.yml index ba22339753..496a578c91 100644 --- a/.gitlab-ci.yml +++ b/.gitlab-ci.yml @@ -33,6 +33,9 @@ merge: -

This will allow for a second call to set_initialized() after a call to query_initialized() to replicate the existing behavior of query_initialized() after MOM6 PR #149 (https://github.com/NOAA-GFDL/MOM6/pull/149) has been accepted. All answers are bitwise identical, but there is a new public interface. --- src/framework/MOM_restart.F90 | 174 +++++++++++++++++++++++++++++++--- 1 file changed, 163 insertions(+), 11 deletions(-) diff --git a/src/framework/MOM_restart.F90 b/src/framework/MOM_restart.F90 index 9df5d39818..7081bbd0fb 100644 --- a/src/framework/MOM_restart.F90 +++ b/src/framework/MOM_restart.F90 @@ -136,6 +136,13 @@ module MOM_restart module procedure query_initialized_4d, query_initialized_4d_name end interface +!> Specify that a field has been initialized, even if it was not read from a restart file +interface set_initialized + module procedure set_initialized_name, set_initialized_0d_name + module procedure set_initialized_1d_name, set_initialized_2d_name + module procedure set_initialized_3d_name, set_initialized_4d_name +end interface + contains !> Register a restart field as obsolete @@ -571,7 +578,7 @@ end subroutine register_restart_field_0d !> query_initialized_name determines whether a named field has been successfully -!!

Now we record the command line to achieve the same re-run ability. - Adds new option "-e" to link all externals. - This was the default before but I think in time we can make this approach more intelligent and figure out which functions/subroutines are used elsewhere. - Processes F90 `include` to build dependencies - Currently not tested with nested `include`s Comments: - As usual, the bizarre self-referencing in drifters.F90 needed some special handling. The self-referencing is associated with code in CPP block to generate local test programs. Now, we filter out circular self-references rather than complain like make does. A large-separation circular dependence will not be caught and lead to unpreditable behavior. Such circular dependence is not something that makes sense to support or allow. - Using only native python featues, no packages, to avoid the "package dependence" we are trying to avoid with makedep. - This python version appears to be of orders of magnitude faster than the bash version. Should have started here ... Todo: [ ] Improve some list/dictionary comprehensions. We use list comprehensions quite a lot but a few "clunky" functions remain when the first attempt at a comprehension failed. I never figrued out a working dictionary comprehension. [ ] Add a solution for the need to always link "externals". --- ac/Makefile.in | 2 +- ac/deps/Makefile.fms.in | 2 +- ac/makedep | 534 +++++++++++++++++++++++----------------- 3 files changed, 311 insertions(+), 227 deletions(-) diff --git a/ac/Makefile.in b/ac/Makefile.in index 2e482ab0c5..599381a35b 100644 --- a/ac/Makefile.in +++ b/ac/Makefile.in @@ -28,7 +28,7 @@ Makefile: @srcdir@/ac/Makefile.in config.status .PHONY: depend depend: Makefile.dep Makefile.dep: - $(MAKEDEP) -o Makefile.dep $(SRC_DIRS) + $(MAKEDEP) -o Makefile.dep -e $(SRC_DIRS) # Delete any files associated with configuration (including the Makefile). diff --git a/ac/deps/Makefile.fms.in b/ac/deps/Makefile.fms.in index fc580a8c9e..e2581cf817 100644 --- a/ac/deps/Makefile.fms.in +++ b/ac/deps/Makefile.fms.in @@ -22,4 +22,4 @@ ARFLAGS = @ARFLAGS@ .PHONY: depend depend: Makefile.dep Makefile.dep: - $(MAKEDEP) -o Makefile.dep -x libFMS.a @srcdir@ + $(MAKEDEP) -o Makefile.dep -e -x libFMS.a @srcdir@ diff --git a/ac/makedep b/ac/makedep index 74d9200ce8..f580d522e1 100755 --- a/ac/makedep +++ b/ac/makedep @@ -1,225 +1,309 @@ -#!/bin/bash - -usage() { - echo "Construct Makfile.dep containing dependencies for F90 source code." - echo - echo "Syntax:" $0 "[-h|d] [-o FILE] [-x EXEC] PATH [PATH] [...]" - echo - echo "arguments:" - echo " PATH Directories containing source code.

Autoconf now includes macros to determine the following: * The name of sigsetjmp: `sigsetjmp` (BSD) or `__sigsetjmp` (Linux) * The size of `jmp_buf` and `sigjmp_buf`. Also renamed to `SIZEOF_*` to align with autoconf macro name conventions. The Linux defaults are retained in `posix.h`, but autoconf will now override these values. Two CI tests for MacOS have also been added, replicating the "stencil" and "regression" tests. The testing-setup has also been restructured to account for multiple platforms. Currently only Ubuntu and MacOS are tested. --- .github/actions/macos-setup/action.yml | 17 ++++++++++++ .github/actions/testing-setup/action.yml | 9 ------- .github/actions/ubuntu-setup/action.yml | 19 +++++++++++++ .github/workflows/coupled-api.yml | 2 ++ .github/workflows/coverage.yml | 2 ++ .github/workflows/expression.yml | 2 ++ .github/workflows/macos-regression.yml | 34 ++++++++++++++++++++++++ .github/workflows/macos-stencil.yml | 34 ++++++++++++++++++++++++ .github/workflows/other.yml | 2 ++ .github/workflows/perfmon.yml | 2 ++ .github/workflows/regression.yml | 2 ++ .github/workflows/stencil.yml | 2 ++ ac/configure.ac | 32 ++++++++++++++++++---- src/framework/posix.F90 | 4 +-- src/framework/posix.h | 10 +++---- 15 files changed, 151 insertions(+), 22 deletions(-) create mode 100644 .github/actions/macos-setup/action.yml create mode 100644 .github/actions/ubuntu-setup/action.yml create mode 100644 .github/workflows/macos-regression.yml create mode 100644 .github/workflows/macos-stencil.yml diff --git a/.github/actions/macos-setup/action.yml b/.github/actions/macos-setup/action.yml new file mode 100644 index 0000000000..645a51b619 --- /dev/null +++ b/.github/actions/macos-setup/action.yml @@ -0,0 +1,17 @@ +name: 'install-macos-prerequisites' + +description: 'Install prerequisites for Mac OS compilation' + +runs: + using: 'composite' + + steps: + -

This commit addresses the issue with the dumbbell subdomain test case not exhibiting proper rescaling for salinity as described in https://github.com/NOAA-GFDL/MOM6/issues/148. Some incorrect unit descriptions in comments were also corrected, and the tracer name comparisons for setting rescaling were made case-insensitive to handle some inconsistently cased name declarations. All answers without dimensional rescaling are bitwise identical. --- src/core/MOM_open_boundary.F90 | 49 +++++++++++++++++++++++++--------- 1 file changed, 36 insertions(+), 13 deletions(-) diff --git a/src/core/MOM_open_boundary.F90 b/src/core/MOM_open_boundary.F90 index a5382910b8..c768654cc4 100644 --- a/src/core/MOM_open_boundary.F90 +++ b/src/core/MOM_open_boundary.F90 @@ -19,7 +19,7 @@ module MOM_open_boundary use MOM_restart, only : register_restart_field, register_restart_pair use MOM_restart, only : query_initialized, MOM_restart_CS use MOM_obsolete_params, only : obsolete_logical, obsolete_int, obsolete_real, obsolete_char -use MOM_string_functions, only : extract_word, remove_spaces +use MOM_string_functions, only : extract_word, remove_spaces, uppercase use MOM_tidal_forcing, only : astro_longitudes, astro_longitudes_init, eq_phase, nodal_fu, tidal_frequency use MOM_time_manager, only : set_date, time_type, time_type_to_real, operator(-) use MOM_tracer_registry, only : tracer_type, tracer_registry_type, tracer_name_lookup @@ -309,6 +309,7 @@ module MOM_open_boundary real, allocatable :: cff_normal(:,:,:) !< Array storage for oblique boundary condition restarts [L2 T-2 ~> m2 s-2] real, allocatable :: tres_x(:,:,:,:) !< Array storage of tracer reservoirs for restarts, in unscaled units [conc] real, allocatable :: tres_y(:,:,:,:) !< Array storage of tracer reservoirs for restarts, in unscaled units [conc] + logical :: debug !< If true, write verbose checksums for debugging purposes. real :: silly_h !< A silly value of thickness outside of the domain that can be used to test !! the independence of the OBCs to this external data [H ~> m or kg m-2]. real :: silly_u !< A silly value of velocity outside of the domain that can be used to test @@ -365,7 +366,7 @@ subroutine open_boundary_config(G, US, param_file, OBC) !

By default, all expressions are mathematically equivalent, but there are roundoff level changes in the topography and sponges due to the use of more generally valid expressions with runtime parameters and the replacement of some divisions for unit conversions by multiplication by a reciprocal. Because the DOME test cases are strongly nonlinear, these small changes cascade up to macroscopic differences, but these are of comparable magnitude to the differences between compilers. There are 10 new runtime parameters that appear in the MOM_parameter_doc.all files for the DOME test cases. --- src/user/DOME_initialization.F90 | 122 +++++++++++++++++++++---------- 1 file changed, 84 insertions(+), 38 deletions(-) diff --git a/src/user/DOME_initialization.F90 b/src/user/DOME_initialization.F90 index ceef4a3a93..e8a6ae713c 100644 --- a/src/user/DOME_initialization.F90 +++ b/src/user/DOME_initialization.F90 @@ -46,7 +46,13 @@ subroutine DOME_initialize_topography(D, G, param_file, max_depth, US) type(unit_scale_type), intent(in) :: US !< A dimensional unit scaling type !

These had been given the inverse of the correct values. An optional scale argument was also added (with its default value) in the call to set up ALE sponge velocities, for greater clarity of what this call is doing. This commit should address an issue noted by Kate Hedstrom when evaluating the first draft of PR #1577 from dev/gfdl to main. All answers are bitwise identical in cases where dimensional rescaling of temperature and salinity are not being applied, and answers with the rescaling of temperature and salinity should now reproduce those without the rescaling. --- src/initialization/MOM_state_initialization.F90 | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/src/initialization/MOM_state_initialization.F90 b/src/initialization/MOM_state_initialization.F90 index cd6ddbeca7..257d25dad0 100644 --- a/src/initialization/MOM_state_initialization.F90 +++ b/src/initialization/MOM_state_initialization.F90 @@ -2138,15 +2138,16 @@ subroutine initialize_sponges_file(G, GV, US, use_temperature, tv, u, v, depth_t endif !

This commit reproduces the model's behavior prior to the removal of the code that set the initialized flag within query_initialized in https://github.com/NOAA-GFDL/MOM6/pull/149, and it completes the set of changes that was envisioned when set_initialized was added in https://github.com/NOAA-GFDL/MOM6/pull/152.

The dependency generation was being invoked twice - The dependency generation was not invoked when source code was changed. Now: - `./configure` creates config.status Makefile and Makefile.dep - `./config.status` recreates Makefile and Makefile.dep - `make depend` recreates Makefile.dep - `make` will conditionally recreate Makefile.dep Changes: - Add dependency of Makefile.dep on source code in Makefile.in. This allows `make` to know when to run `makedep`. - Fix syntax issue for AC_CONFIG_COMMANDS which caused errors to be issued without stopping. Side note: the system works perfectly well if we comment out the "AC_CONFIG_COMMANDS" line in configure.ac to invoke makedep.

also renamed the old FCFLAGS_FMS to FCFLAGS_DEPS, which was previously used to pass the flags to the FMS library/modfiles * $(DEPS) was dropped, and we just use `deps` now. * Updated the header instructions * README update * Codecov.io and GitHub Actions CIs were updated to support changes --- .codecov.yml | 4 -

While making these changes, several incorrect or missing variable unit descriptions in comments were identified and corrected. This set of changes is mathematically equivalent, but will result in changes at the level of roundoff, either because the order of sums was changed or because divisions are replaced by multiplication by a common reciprocal. Some debugging safety checks were moved inside of a logical test of the debug flag for efficiency. One dimensionally inconsistent expression (in vertical and horizontal distances) was corrected, so that it should now pass the dimensional consistency checks. This commit will change answers in any cases that depend on this code, but because we recently corrected (in MOM6 PR#154) a major bug in this code with a much larger impact without causing any disruptions, we can be confident that this code is not yet used in an production runs where minor answer changes could be problematic. This code change does not alter any answers or output in the MOM6-examples test suite. --- src/diagnostics/MOM_wave_structure.F90 | 205 ++++++++++++++----------- 1 file changed, 118 insertions(+), 87 deletions(-) diff --git a/src/diagnostics/MOM_wave_structure.F90 b/src/diagnostics/MOM_wave_structure.F90 index d11a7af5ec..6241aef386 100644 --- a/src/diagnostics/MOM_wave_structure.F90 +++ b/src/diagnostics/MOM_wave_structure.F90 @@ -42,7 +42,8 @@ module MOM_wave_structure real, allocatable, dimension(:,:,:) :: w_strct !< Vertical structure of vertical velocity (normalized) [nondim]. real, allocatable, dimension(:,:,:) :: u_strct - !< Vertical structure of horizontal velocity (normalized) [nondim]. + !< Vertical structure of horizontal velocity (normalized and + !! divided by layer thicknesses) [Z-1 ~> m-1]. real, allocatable, dimension(:,:,:) :: W_profile !< Vertical profile of w_hat(z), where !! w(x,y,z,t) = w_hat(z)*exp(i(kx+ly-freq*t)) is the full time- @@ -141,7 +142,7 @@ subroutine wave_structure(h, tv, G, GV, US, cn, ModeNum, freq, CS, En, full_halo HxS_here, & !< A layer integrated salinity [S Z ~> ppt m] HxR_here !< A layer integrated density [R Z ~> kg m-2] real :: I_Hnew !< The inverse of a new layer thickness [Z-1 ~> m-1] - real :: drxh_sum !< The sum of density diffrences across interfaces times thicknesses [R Z ~> kg m-2] + real :: drxh_sum !< The sum of density differences across interfaces times thicknesses [R Z ~> kg m-2] real, parameter :: tol1 = 0.0001, tol2 = 0.001 real :: g_Rho0 !< G_Earth/Rho0 in [L2 Z-1 T-2 R-1 ~> m4 s-2 kg-1]. ! real :: rescale, I_rescale @@ -152,40 +153,47 @@ subroutine wave_structure(h, tv, G, GV, US, cn, ModeNum, freq, CS, En, full_halo real :: I_a_int !< inverse of a_int [nondim] real :: f2 !< squared Coriolis frequency [T-2 ~> s-2] real :: Kmag2 !< magnitude of horizontal wave number squared [L-2 ~> m-2] + real :: emag2 !

Several unused variables were also removed, and a missing allocate and restart registration were added for the running-mean salinity in the (as yet unused) MOM_controlled_forcing module.

Previously, there had been 4 calls where this was missing, which led to the problems noted at https://github.com/mom-ocean/MOM6/issues/1576. This PR will allow that issue to be closed. Also used the default argument in a get_param call for INPUTDIR, although that case would not change any behavior because the value was set before the get_param call. A fail_in_missing argument was added to the FMS_cap call to get_param for GUST_2D_FILE, mirroring what is done for the solo_driver code, but cases where this was actually missing were very likely to have failed later anyway, but without an explicit error message.

These changes were proposed in https://github.com/mom-ocean/MOM6/issues/1565 and discussed and agreed to at the MOM6 dev call on 4/25/22. Previously these diagnostics had been converted to approximate thicknesses in m using a constant reference density, but this was only accurate to about 0.1% and could be misinterpreted. A number of other (more commonly used) thickness-related variables were already being written in their native units, and this makes the model's output more self consistent.

All answers are bitwise identical, but there are new optional arguments to numerous publicly visible routines. --- src/ALE/P1M_functions.F90 | 6 ++- src/ALE/P3M_functions.F90 | 11 ++++-- src/ALE/PPM_functions.F90 | 10 +++-- src/ALE/PQM_functions.F90 | 10 +++-- src/ALE/regrid_edge_values.F90 | 25 ++++++++++--- src/ALE/regrid_solvers.F90 | 8 +++- src/framework/MOM_horizontal_regridding.F90 | 41 ++++++++++++++------- 7 files changed, 76 insertions(+), 35 deletions(-) diff --git a/src/ALE/P1M_functions.F90 b/src/ALE/P1M_functions.F90 index d99c611229..281971cca4 100644 --- a/src/ALE/P1M_functions.F90 +++ b/src/ALE/P1M_functions.F90 @@ -24,7 +24,7 @@ module P1M_functions !! !!

In some cases, this also involves replacing one of the elements in an opaque type. It can also involve reading (but not yet logging) the new runtime parameter DEFAULT_ANSWER_DATE, but if it not set the results are unchanged from before. There is also a new optional argument, remap_answer_date, to wave_speed_init and wave_speed_set_param. Some comments were also added to describe real variables in VarMix_init.

The variable is disabled on default, to reduce the amount of output at command line. It has been added to the GitHub Actions CI, and is propagated through `.testing/Makefile`. Although not used in the MOM6 builds, it could be extended to them if it proves useful.

To fix this, separate interfaces for tensors with 1-4 dimensions replace the assumed rank subroutines. This does not interfere with the SmartRedis library as the public (overloaded) interface still retains the same API. Additionally, some methods which are likely unique to the SmartRedis client have been removed to enhance the likelihood of providing a general database client API to be used by other implementations. --- config_src/external/database_comms/README.md | 8 +- .../database_client_interface.F90 | 622 ++++++++---------- 2 files changed, 264 insertions(+), 366 deletions(-) diff --git a/config_src/external/database_comms/README.md b/config_src/external/database_comms/README.md index 53a06b0a4a..05f1f07259 100644 --- a/config_src/external/database_comms/README.md +++ b/config_src/external/database_comms/README.md @@ -18,6 +18,8 @@ code in the new implementation is part of `MOM_MEKE.F90`. control structure that are imported elsewhere within the primary MOM6 code.

This reduces some unnecessary calculations. * Two new subroutines replaced the original `porous_widths`. They could be combined with interface if we remove porous_barrier_ptrs type, and use variables (of different nz) as output. * There is a place holder switch do_next in the two calc_por subs. This is used to further reduce calculations for all layers above D_max. Will be tested and implemented in the next commit. * A new subroutine calc_eta_at_uv is added to calculate eta at uv. This simplifies the code, but also increases stack and some performance overhead. --- src/core/MOM.F90 | 7 +- src/core/MOM_porous_barriers.F90 | 321 +++++++++++++++++++++---------- 2 files changed, 224 insertions(+), 104 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index ea5baf6116..7865c7aa04 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -103,7 +103,8 @@ module MOM use MOM_open_boundary, only : open_boundary_register_restarts use MOM_open_boundary, only : update_segment_tracer_reservoirs use MOM_open_boundary, only : rotate_OBC_config, rotate_OBC_init -use MOM_porous_barriers, only : porous_barrier_CS, porous_widths, porous_barriers_init +use MOM_porous_barriers, only : porous_widths_layer, porous_widths_interface, porous_barriers_init +use MOM_porous_barriers, only : porous_barrier_CS use MOM_set_visc, only : set_viscous_BBL, set_viscous_ML use MOM_set_visc, only : set_visc_register_restarts, set_visc_CS use MOM_set_visc, only : set_visc_init, set_visc_end @@ -1090,7 +1091,7 @@ subroutine step_MOM_dynamics(forces, p_surf_begin, p_surf_end, dt, dt_thermo, & !

The default is True at the moment to assist potential test. It should be changed to false in the future. * A boolean array is added to avoid unnecessary porous barrier calculations above the shallowest points. * The layer-averaged weights are bounded by 1.0 explicitly, to avoid the cases it goes beyond due to roundoff errors. * For very thin layers (Angstrom), layer-averaged weights are set to zeros for simplicity. * Perhaps it is more reasonable to use the inferace weight for these cases. * It might be useful to make the thin layer definition a runtime parameter. * A bug related the size of eta_[uv] is fixed. This commit is potentially answer-changing when the porouss barrier module is used. --- src/core/MOM.F90 | 31 +++++++++------ src/core/MOM_porous_barriers.F90 | 68 ++++++++++++++++++++------------ 2 files changed, 62 insertions(+), 37 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 7865c7aa04..8d2556f185 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -413,6 +413,7 @@ module MOM !! ensemble model state vectors and data assimilation !! increments and priors type(dbcomms_CS_type) :: dbcomms_CS !< Control structure for database client used for online ML/AI + logical :: use_porbar type(porous_barrier_ptrs) :: pbv !< porous barrier fractional cell metrics type(particles), pointer :: particles => NULL() !

This new capability is enabled with the new runtime parameter APPLY_INTERFACE_FILTER, and with rates of filtering determined by the new runtime parameters INTERFACE_FILTER_TIME, INTERFACE_FILTER_MAX_CFL, INTERFACE_FILTER_ORDER and INTERFACE_FILTER_ISOTROPIC. Set APPLY_INTERFACE_FILTER to True and provide a positive timescale in INTERFACE_FILTER_TIME to enable the filtering. The comments describing THICKNESSDIFFUSE and THICKNESSDIFFUSE_FIRST were also updated to clarify the distinctions with the new capabilities or to clearly identify which parameters work together. By default, all answers are bitwise identical, but there are new entries or modified comments in the MOM_parameter_doc files. --- src/core/MOM.F90 | 91 +++- src/core/MOM_variables.F90 | 2 + .../lateral/MOM_interface_filter.F90 | 468 ++++++++++++++++++ 3 files changed, 534 insertions(+), 27 deletions(-) create mode 100644 src/parameterizations/lateral/MOM_interface_filter.F90 diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 7444597bbb..f6c714b3be 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -90,6 +90,8 @@ module MOM use MOM_hor_index, only : hor_index_type, hor_index_init use MOM_hor_index, only : rotate_hor_index use MOM_interface_heights, only : find_eta +use MOM_interface_filter, only : interface_filter, interface_filter_init, interface_filter_end +use MOM_interface_filter, only : interface_filter_CS use MOM_lateral_mixing_coeffs, only : calc_slope_functions, VarMix_init, VarMix_end use MOM_lateral_mixing_coeffs, only : calc_resoln_function, calc_depth_function, VarMix_CS use MOM_MEKE, only : MEKE_alloc_register_restart, step_forward_MEKE @@ -276,6 +278,8 @@ module MOM logical :: split !< If true, use the split time stepping scheme. logical :: use_RK2 !< If true, use RK2 instead of RK3 in unsplit mode !!

Since Fortran C bindings require a symbol, we cannot bind to macro implementations. The prior implementation assumed a Linux glibc binding of __sigsetjmp (accessed by a `sigsetjmp` macro), but this did not work on BSD and MacOS builds, which have a dedicated `sigsetjmp` symbol. Although the autoconf build included a macro to test and assign the symbol to `SIGSETJMP_NAME`, this did not resolve builds based on mkmf or similar build systems, and would fail to compile. To resolve this, the SIGSETJMP_NAME points to a placeholder function, `sigsetjmp_missing` which permits compilation but raises an error if called. Since this function is only used in our unit testing, and even then only for tests which would otherwise raise FATAL, this change will not disrupt any simulations. However, it does mean that only "power" users who build with either autoconf or `-DSIGSETJMP_NAME=\"...\"` will be able to run the unit tests. In practice, it should be sufficient to direct users to the autoconf builds, and no actual disruptions are expected. --- ac/configure.ac | 31 +++++++++++++++++++------------ src/framework/posix.F90 | 18 ++++++++++++++++++ src/framework/posix.h | 2 +- 3 files changed, 38 insertions(+), 13 deletions(-) diff --git a/ac/configure.ac b/ac/configure.ac index dc4962307e..8d74d71fbd 100644 --- a/ac/configure.ac +++ b/ac/configure.ac @@ -234,21 +234,28 @@ AC_SUBST([SRC_DIRS], AC_CONFIG_COMMANDS(Makefile.dep, [make depend]) -# setjmp verification +# POSIX verification tests AC_LANG_PUSH([C]) -# Verify that either sigsetjmp (POSIX) or __sigsetjmp (glibc) are available. -AC_CHECK_FUNC([sigsetjmp]) -AS_IF([test "$ac_cv_func_sigsetjmp" == "yes"], [ - SIGSETJMP_NAME="sigsetjmp" -], [ - AC_CHECK_FUNC([__sigsetjmp], [ - SIGSETJMP_NAME="__sigsetjmp" - ], [ - AC_MSG_ERROR([Could not find a symbol for sigsetjmp.]) +# These symbols may be defined as macros, making them inaccessible by Fortran. +# The following exist in BSD and Linux, so we just test for them. +AC_CHECK_FUNC([setjmp], [], [AC_MSG_ERROR([Could not find setjmp.])]) +AC_CHECK_FUNC([longjmp], [], [AC_MSG_ERROR([Could not find longjmp.])]) +AC_CHECK_FUNC([siglongjmp], [], [AC_MSG_ERROR([Could not find siglongjmp.])]) + +# Determine the sigsetjmp symbol.

This constant mixed layer diffusivity was formerly set with KDML, but is now set with KD_ML_TOT, but KDML will still work for input but is no longer logged and triggers a warning message if it is used. Also removed KDML from the description of the ADIABATIC option. This leads to changes in the entries of several MOM_parameter_doc files, and it could lead to answer changes that set a non-default value of KDML and use ePBL or KPP, but it seems unlikely that any such cases would exist. --- src/core/MOM.F90 | 7 +- .../vertical/MOM_bkgnd_mixing.F90 | 77 ++++++++++++------- .../vertical/MOM_diabatic_driver.F90 | 5 +- .../vertical/MOM_set_diffusivity.F90 | 11 ++- .../vertical/MOM_set_viscosity.F90 | 7 +- 5 files changed, 69 insertions(+), 38 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index f6c714b3be..267a162b00 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -1982,10 +1982,9 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, restart_CSp, & default=.false.)

This was done by adding the new subroutine stresses_to_ustar to start to standardize the calculation of the friction velocities from the wind stresses. Neverworld_wind_forcing and wind_forcing_gyres were already using the same expressions for ustar as are in stresses_to_ustar, so the new routine is now used in these cases. In other routines that set ustar, the answers differ at roundoff due to the difference between division by a reference density and multiplication by its reciprocal, so using the new subroutine in those cases should be wrapped in an answer_date flag, which is being left for a later commit. This is being added now as a result of a new commit that uses ustar as a part of the specification of viscosities even in idealized cases.

The if-blocks used to evaluate the piecewise function was replaced with a sequence of min/max evaluations, which are vectorizable. A nondimensional subroundoff term is also introducted to address the division by zero in the evaluation of 1 - 0.5 * Instep / visc_rem. When visc_rem is zero, this term will never be selected by the max() operator, since it is negatively asymptotic. When visc_rem is sufficiently large to accept this term, the value of subroundoff is too small to modify the significand of the floating point value.

Also completed obsoleting of HENYEY_IGW_BACKGROUND_NEW. This PR will change answers in some cases, unless the MOM_input files already included lines with the following settings, or otherwise explicitly set these parameters: KV_ML_INVZ2 = 0.0 BAROTROPIC_TIDAL_SAL_BUG = False LAYER_Z_INIT_IC_EXTRAP_BUG = False KAPPA_SHEAR_VERTEX_PSURF_BUG = False For each of these parameters, there is another parameter (such as BULKMIXEDLAYER or TIDES) whose value determines whether they might be used in a particular case. To determine whether or why answers for a particular configuration might change with this PR, compare the MOM_parameter_doc.all files from equivalent runs before and after these code changes to determine whether any of these parameters are taking the default value. This commit could change answers in some cases that use default values for these parameters, and the entries in some MOM_parameter_doc files will change. The answers in the MOM6-examples test suite are bitwise identical, due to some entries that were recently added to the MOM_input files for these cases. --- src/core/MOM_barotropic.F90 | 2 +- .../MOM_state_initialization.F90 | 2 +- .../vertical/MOM_bkgnd_mixing.F90 | 23 +------------------ .../vertical/MOM_kappa_shear.F90 | 2 +- .../vertical/MOM_vert_friction.F90 | 9 ++++---- 5 files changed, 8 insertions(+), 30 deletions(-) diff --git a/src/core/MOM_barotropic.F90 b/src/core/MOM_barotropic.F90 index 83cc0b7d09..5aceee34ef 100644 --- a/src/core/MOM_barotropic.F90 +++ b/src/core/MOM_barotropic.F90 @@ -4476,7 +4476,7 @@ subroutine barotropic_init(u, v, h, eta, Time, G, GV, US, param_file, diag, CS, "If true, the tidal self-attraction and loading anomaly in the barotropic "//& "solver has the wrong sign, replicating a long-standing bug with a scalar "//& "self-attraction and loading term or the SAL term from a previous simulation.", & - default=.true., do_not_log=(det_de==0.0)) + default=.false., do_not_log=(det_de==0.0)) call get_param(param_file, mdl, "SADOURNY", CS%Sadourny, & "If true, the Coriolis terms are discretized with the "//& "Sadourny (1975) energy conserving scheme, otherwise "//& diff --git a/src/initialization/MOM_state_initialization.F90 b/src/initialization/MOM_state_initialization.F90 index 58a6f9ed8d..0eac15f6d7 100644 --- a/src/initialization/MOM_state_initialization.F90 +++ b/src/initialization/MOM_state_initialization.F90 @@ -2651,7 +2651,7 @@ subroutine MOM_temp_salt_initialize_from_Z(h, tv, depth_tot, G, GV, US, PF, just "If true use an expression with a vertical indexing bug for extrapolating the "//& "densities at the bottom of unstable profiles from data when finding the "//& "initial interface locations in layered mode from a dataset of T and S.", & - default=.true., do_not_log=just_read) + default=.false., do_not_log=just_read) !

But in the meantime, we will need to ensure that all unit-based `close_file` calls were not opened with `mpp_open`. There is also a minor patch to `.testing/Makefile` which selects the framework ("infra") source dependency, rather than hard-set to FMS1. --- .testing/Makefile | 19 +++- config_src/infra/FMS2/MOM_io_infra.F90 | 132 ++++++++++++++++++++++--- 2 files changed, 136 insertions(+), 15 deletions(-) diff --git a/.testing/Makefile b/.testing/Makefile index 2bd9c6f39d..530a552181 100644 --- a/.testing/Makefile +++ b/.testing/Makefile @@ -182,14 +182,25 @@ endif SOURCE = \ $(foreach ext,F90 inc c h,$(wildcard $(1)/*/*.$(ext) $(1)/*/*/*.$(ext))) -MOM_SOURCE = $(call SOURCE,../src) \ - $(wildcard ../config_src/infra/FMS1/*.F90) \ +MOM_SOURCE = \ + $(call SOURCE,../src) \ $(wildcard ../config_src/drivers/solo_driver/*.F90) \ $(wildcard ../config_src/ext*/*/*.F90) -TARGET_SOURCE = $(call SOURCE,build/target_codebase/src) \ - $(wildcard build/target_codebase/config_src/infra/FMS1/*.F90) \ + +TARGET_SOURCE = \ + $(call SOURCE,build/target_codebase/src) \ $(wildcard build/target_codebase/config_src/drivers/solo_driver/*.F90) \ $(wildcard build/target_codebase/config_src/ext*/*.F90) + +# NOTE: Current default framework is FMS1, but this could change. +ifeq ($(FRAMEWORK), fms2) + MOM_SOURCE +=$(wildcard ../config_src/infra/FMS2/*.F90) + TARGET_SOURCE += $(wildcard build/target_codebase/config_src/infra/FMS2/*.F90) +else + MOM_SOURCE += $(wildcard ../config_src/infra/FMS1/*.F90) + TARGET_SOURCE += $(wildcard build/target_codebase/config_src/infra/FMS1/*.F90) +endif + FMS_SOURCE = $(call SOURCE,deps/fms/src) diff --git a/config_src/infra/FMS2/MOM_io_infra.F90 b/config_src/infra/FMS2/MOM_io_infra.F90 index c8c55524f8..dc8a9af3d5 100644 --- a/config_src/infra/FMS2/MOM_io_infra.F90 +++ b/config_src/infra/FMS2/MOM_io_infra.F90 @@ -19,7 +19,7 @@ module MOM_io_infra use fms2_io_mod, only : get_global_io_domain_indices use fms_io_utils_mod, only : fms2_file_exist => file_exists -use fms_mod, only : write_version_number, open_namelist_file, check_nml_error +use fms_mod, only : write_version_number, check_nml_error use fms_io_mod, only : file_exist, field_exist, field_size, read_data use fms_io_mod, only : fms_io_exit, get_filename_appendix use mpp_domains_mod, only : mpp_get_compute_domain, mpp_get_global_domain @@ -31,6 +31,8 @@ module MOM_io_infra use mpp_io_mod, only : mpp_get_info, mpp_get_times use mpp_io_mod, only : mpp_io_init use mpp_mod, only : stdout_if_root=>stdout +use mpp_mod, only : mpp_pe, mpp_root_pe, mpp_npes +use mpp_mod, only : mpp_get_current_pelist_name !

The description for ri_grad_shear is misleading. If smoothing is applied, ri_grad_shear *is not* the RI number used by MOM_CVMix_shear module. In this commit. I propose to avoid this potential confusion by renaming ri_grad_shear_smooth to ri_grad_shear_orig and, if N_SMOOTH_RI > 0, use ri_grad_shear to store the smoothed profiles. * ri_grad_shear_orig : Original gradient Richarson number, before smoothing was applied.

Versions of this routine that work on 2d, 3d or 4d arrays and pairs of 3d arrays have been added for now, although the pattern should be clear enough if other sizes of arrays are needed. They use the new private routine find_var_in_restart_files to determine whether a named variable is in the restart files and the full path to the appropriate file. These routines allow for the contents of the restart files to be gracefully altered, while preserving the ability to use restart files with the previous format.

This change is controlled by the new runtime parameter STORE_CORIOLIS_ACCEL, and it leads to changes in the fields that are saved in the restart files. This commit also includes the necessary changes to allow the restart files written in one mode to be read in the other and give bitwise identical restarts. Because the next step's predictor CAu and CAv accelerations now have to coexist with the previous step's CAu and CAv accelerations, which are used for derived diagnostics (like energy budget terms), the predictor CAu and CAv terms have to be stored in new variables, CS%CAu_pred and CS%CAv_pred, and there is a new accel_diag_ptrs type in the dyn_split_RK2 control structure to diagnose truncation errors arising in the predictor step. Several comments have also been modified to document the dimensions of variables. All answers and diagnostics are bitwise identical. --- src/core/MOM_dynamics_split_RK2.F90 | 258 ++++++++++++++++++++-------- 1 file changed, 183 insertions(+), 75 deletions(-) diff --git a/src/core/MOM_dynamics_split_RK2.F90 b/src/core/MOM_dynamics_split_RK2.F90 index f06c692eaf..d95c6feea3 100644 --- a/src/core/MOM_dynamics_split_RK2.F90 +++ b/src/core/MOM_dynamics_split_RK2.F90 @@ -21,16 +21,17 @@ module MOM_dynamics_split_RK2 use MOM_domains, only : To_South, To_West, To_All, CGRID_NE, SCALAR_PAIR use MOM_domains, only : To_North, To_East, Omit_Corners use MOM_domains, only : create_group_pass, do_group_pass, group_pass_type -use MOM_domains, only : start_group_pass, complete_group_pass, pass_var +use MOM_domains, only : start_group_pass, complete_group_pass, pass_var, pass_vector use MOM_debugging, only : hchksum, uvchksum use MOM_error_handler, only : MOM_error, MOM_mesg, FATAL, WARNING, is_root_pe use MOM_error_handler, only : MOM_set_verbosity, callTree_showQuery use MOM_error_handler, only : callTree_enter, callTree_leave, callTree_waypoint use MOM_file_parser, only : get_param, log_version, param_file_type use MOM_get_input, only : directories -use MOM_io, only : vardesc, var_desc +use MOM_io, only : vardesc, var_desc, EAST_FACE, NORTH_FACE use MOM_restart, only : register_restart_field, register_restart_pair use MOM_restart, only : query_initialized, set_initialized, save_restart +use MOM_restart, only : only_read_from_restarts use MOM_restart, only : restart_init, is_new_run, MOM_restart_CS use MOM_time_manager, only : time_type, time_type_to_real, operator(+) use MOM_time_manager, only : operator(-), operator(>), operator(*), operator(/) @@ -77,12 +78,14 @@ module MOM_dynamics_split_RK2 type, public :: MOM_dyn_split_RK2_CS ; private real ALLOCABLE_, dimension(NIMEMB_PTR_,NJMEM_,NKMEM_) :: & CAu, & !< CAu = f*v - u.grad(u) [L T-2 ~> m s-2] + CAu_pred, & !< The predictor step value of CAu = f*v - u.grad(u) [L T-2 ~> m s-2] PFu, & !< PFu = -dM/dx [L T-2 ~> m s-2] PFu_Stokes, & !< PFu_Stokes = -d/dx int_r (u_L*duS/dr) [L T-2 ~> m s-2] diffu !< Zonal acceleration due to convergence of the along-isopycnal stress tensor [L T-2 ~> m s-2] real ALLOCABLE_, dimension(NIMEM_,NJMEMB_PTR_,NKMEM_) :: & CAv, & !< CAv = -f*u - u.grad(v) [L T-2 ~> m s-2] + CAv_pred, & !< The predictor step value of CAv = -f*u - u.grad(v) [L T-2 ~> m s-2] PFv, & !< PFv = -dM/dy [L T-2 ~> m s-2] PFv_Stokes, & !< PFv_Stokes = -d/dy int_r (v_L*dvS/dr) [L T-2 ~> m s-2] diffv !< Meridional acceleration due to convergence of the along-isopycnal stress tensor [L T-2 ~> m s-2] @@ -91,7 +94,7 @@ module MOM_dynamics_split_RK2 !< Both the fraction of the zonal momentum originally in a !! layer that remains after a time-step of viscosity, and the !! fraction of a time-step worth of a barotropic acceleration - !! that a layer experiences after viscosity is applied. + !! that a layer experiences after viscosity is applied [nondim]. !!

The first evolves the ocean state forward in -time according to a vertical Lagrangian limit with \f$\dot{r}=0\f$. Hence, -the horizontal momentum, thickness, and tracers are time stepped -with the red terms removed in equations \eqref{eq:h-horz-momentum,h-equations,momentum}, -\eqref{eq:h-thickness-equation,h-equations,thickness}, \eqref{eq:h-temperature-equation,h-equations,potential temperature}, -and \eqref{eq:h-salinity-equation,h-equations,salinity}. All advective transport thus -occurs within a layer as defined by constant \f$r\f$-surfaces so that -the volume within each layer is fixed. All other terms are retained in -their full form, including subgrid scale terms that contribute to -the transfer of tracer and momentum into distinct \f$r\f$ layers (e.g., -dia-surface diffusion of tracer and velocity). Maintaining constant -volume within a layer yet allowing for tracers to move between layers -engenders no inconsistency between tracer and thickness evolution. The -reason is that tracer diffusion, even dia-surface diffusion, does -not transfer volume. +\image html ALE_general_schematic.png "Schematic of the 3d Lagrangian regrid/remap method" width=70% +\image latex ALE_general_schematic.png "Schematic of the 3d Lagrangian regrid/remap method" width=0.7\textwidth -The second step in the algorithm comprises the generation of a new +Refer to the above figure taken from Griffies, Adcroft, and Hallberg +(2020) \cite Griffies_Adcroft_Hallberg2020.

The code in this commit is a direction translation and adoption of the "parallel SAL" from MPAS-Ocean model developed at the Department of Energy's Los Alamos National Laboratory (Barton et al. (2022) and Brus et al. (2022)). This commit serves as an "MVP" so that the MPAS-Ocean algorithm is functional in MOM6.

This generalization allows the spherical harmonic transforms to applications other than SSH based SAL. * The main loops in the two new subroutine are also simplified. * Child variables in the control structure for SHT are now private. * The associated Legendre polynomials in the diagonal (n=m) is now precomputed and stored, rather than recalculating at every step. This does not have the memory cost as fully precomputing all the polynomials, but still reduces some repeat calculations. The performance appears to be improved with this change. * SAL calculation is simplified as forward transform, scaling and inverse transform. * A few variables names inherited from MPAS-O are changed. --- .../lateral/MOM_spherical_harmonics.f90 | 284 +++++++++++++----- .../lateral/MOM_tidal_forcing.F90 | 235 ++------------- 2 files changed, 225 insertions(+), 294 deletions(-) diff --git a/src/parameterizations/lateral/MOM_spherical_harmonics.f90 b/src/parameterizations/lateral/MOM_spherical_harmonics.f90 index c933213b55..d798098832 100644 --- a/src/parameterizations/lateral/MOM_spherical_harmonics.f90 +++ b/src/parameterizations/lateral/MOM_spherical_harmonics.f90 @@ -1,3 +1,4 @@ +!> Laplace's spherical harmonics transforms (SHT) module MOM_spherical_harmonics use MOM_cpu_clock, only : cpu_clock_id, cpu_clock_begin, cpu_clock_end, & CLOCK_MODULE @@ -5,54 +6,195 @@ module MOM_spherical_harmonics use MOM_file_parser, only : get_param, log_version, param_file_type use MOM_grid, only : ocean_grid_type use MOM_unit_scaling, only : unit_scale_type +use MOM_coms_infra, only : sum_across_PEs implicit none ; private -public spherical_harmonics_init, spherical_harmonics_end, associatedLegendrePolynomials, SHOrderDegreeToIndex +public spherical_harmonics_init, spherical_harmonics_end, SHOrderDegreeToIndex, calc_lmax +public spherical_harmonics_forward, spherical_harmonics_inverse #include -type, public :: sht_CS - integer :: nOrder, lmax - real, allocatable :: sinLatCell(:,:), cosLatCell(:,:) - real, allocatable :: complexFactorRe(:,:,:), complexFactorIm(:,:,:), complexExpRe(:,:,:), complexExpIm(:,:,:) - real, allocatable :: pmnm2(:,:), pmnm1(:,:), pmn(:,:) - real, allocatable :: aRecurrenceCoeff(:,:), bRecurrenceCoeff(:,:) - logical :: bfb +type, public :: sht_CS ; private + logical :: initialized = .False. !< True if this control structure has been initialized. + integer :: nOrder !< Maximum degree of the spherical harmonics [nodim]. + integer :: lmax !< Number of associated Legendre polynomials of nonnegative m [=(nOrder+1)*(nOrder+2)/2] [nodim]. + real, allocatable :: cosCoLatT(:,:) !< Precomputed cosine of colatitude at the t-cells [nondim]. + real, allocatable :: Pmm(:,:,:) !< Precomputed associated Legendre polynomials of which m=n at the t-cells [nondim]. + real, allocatable :: complexFactorRe(:,:,:), complexFactorIm(:,:,:), & !< Precomputed exponential factors + complexExpRe(:,:,:), complexExpIm(:,:,:) !! at the t-cells [nondim]. + real, allocatable :: aRecurrenceCoeff(:,:), bRecurrenceCoeff(:,:) !< Precomputed recurrennce coefficients [nondim]. + logical :: bfb !< True if use reproducable global sums end type sht_CS contains +subroutine spherical_harmonics_forward(G, CS, var, SnmRe, SnmIm, Nd) + type(ocean_grid_type), intent(in) :: G !< The ocean's grid structure. + type(sht_CS), intent(in) :: CS !< Control structure for spherical harmonics trasnforms + real, intent(in) :: var(:,:) !< Input 2-D variable + real, intent(out) :: SnmRe(:), SnmIm(:) !< Real and imaginary SHT coefficients + integer, intent(in), optional :: Nd !< Maximum degree of the spherical harmonics, overriding nOrder + !! in the control structure. + ! local variables + integer :: Nmax !

This makes module MOM_tidal_forcing less chunkier and easier to read. * A new function in module MOM_spherical_harmonics is introduced to calculate the starting index of the first element for each order m, replacing a previous function of a similar purpose but a bit more complicated. --- .../lateral/MOM_load_love_numbers.F90 | 1453 ++++++++++++++++ .../lateral/MOM_spherical_harmonics.f90 | 25

This module contains the subroutines to calculate spherical harmonic transforms (SHT), namely, forward transform +!! of a two-dimensional field into a given number of spherical harmonic modes and its inverse transform. This module +!! is primarily used to but not limited to calculate self-attraction and loading (SAL) term, which is mostly relevant to +!! high frequency motions such as tides. Should other needs arise in the future, this API can be easily modified. +!! Currently, the transforms are for t-cell fields only. +!! +!! This module is stemmed from SAL calculation in Model for Prediction Across Scales (MPAS)-Ocean developed by Los +!! Alamos National Laboratory and University of Michigan (Barton et al. (2022) and Brus et al. (2022)). The algorithm +!! for forward and inverse transforms loosely follows Schaeffer (2013). +!! +!! In forward transform, a two-dimensional physical field can be projected into a series of spherical harmonics. The +!! spherical harmonic coefficient of degree n and order m for a field $f(\theta, \phi)$ is calculated as follows: +!! \f[ +!! f^m_n = \int^{2\pi}_{0}\int^{\pi}_{0}f(\theta,\phi)Y^m_n(\theta,\phi)\sin\theta d\theta d\phi +!! \f] +!! and +!! \f[ +!! Y^m_n(\theta,\phi) = P^m_n(\cos\theta)\exp(im\phi) +!! \f] +!! where $P^m_n(\cos \theta)$ is the normalized associated Legendre polynomial of degree n and order m. $\phi$ is the +!! longitude and $\theta$ is the colatitude. +!! Or, written in the discretized form: +!! \f[ +!! f^m_n = \sum^{Nj}_{0}\sum^{Ni}_{0}f(i,j)Y^m_n(i,j)A(i,j)/r_e^2 +!! \f] +!! where $A$ is the area of the cell and $r_e$ is the radius of the Earth. +!! +!! In inverse transform, the first N degree spherical harmonic coefficients are used to reconstruct a two-dimensional +!! physical field: +!! \f[ +!! f(\theta,\phi) = \sum^N_{n=0}\sum^{n}_{m=-n}f^m_nY^m_n(\theta,\phi) +!! \f] +!! +!! The exponential coefficients are pre-computed and stored in the memory. The associated Legendre polynomials are +!! computed "on-the-fly", using the recurrence relationships to avoid large memory usage and take the advantage of +!! array vectorization. +!! +!! The maximum degree of the spherical harmonics is a runtime parameter and the maximum used by all SHT applications. +!! At the moment, it is only decided by TIDAL_SAL_SHT_DEGREE. +!! +!! The forward transforms involve a global summation. Runtime flag SHT_REPRODUCING_SUM controls whether this is done +!! in a bit-wise reproducing way or not. +!! +!! References: +!! +!!

Before this fix, some of the full 3-d arrays for restarts were being overwritten for oblique OBC segments that join at adjacent corners on the north-east side of tracer points, as is noted in github.com/NOAA-GFDL/MOM6/issues/208. The discussion surrounding this issue confirms that there are cases using oblique OBCs (like some North-West Atlantic cases) that do not past the restart reproducibility tests. Some halo updates were also corrected, in accordance with the introduction of these new variables and their proper staggering locations. In a number of places, the proper case-sensitive horizontal indexing convention, as described in github.com/NOAA-GFDL/MOM6/wiki/Code-style-guide#soft-case-convention, is now being used. This commit also corrected the comments describing a number of the variables in the OBC_segment_type to make it clearer where they are discretized. This changes the names of oblique OBC-related variables in the restart files, but since the previous version did not reproduce across restarts, there does not seem to be any point in retaining those incorrect answers. All answers in the MOM6-examples test suite are bitwise identical, but this will change (fix) solutions with oblique OBCs and OBC_RAD_VEL_WT < 1. --- src/core/MOM_open_boundary.F90 | 242 +++++++++++++++++---------------- 1 file changed, 123 insertions(+), 119 deletions(-) diff --git a/src/core/MOM_open_boundary.F90 b/src/core/MOM_open_boundary.F90 index cabf9272ca..a187ac5b2f 100644 --- a/src/core/MOM_open_boundary.F90 +++ b/src/core/MOM_open_boundary.F90 @@ -116,7 +116,8 @@ module MOM_open_boundary !!

Without open boundary conditions, these arrays are identical to mask2dCu and mask2dCv. These arrays are used in some of the lateral parameterization modules to zero out certain gradient-dependent fluxes at open boundary points. With these changes, the Bering test case solutions no longer exhibit any dependence on whether DEBUG_OBC is true or false or the value of OBC_SILLY_THICK, so this commit should help to address some of the issues discussed in github.com/NOAA-GFDL/MOM6/issues/208. All answers are bitwise identical in the MOM6-examples test cases, but they change for some other tests that use open boundary conditions more extensively, and there are new arrays in some transparent types. --- src/core/MOM_grid.F90 | 11 ++- src/core/MOM_open_boundary.F90 | 36 +++++-- src/core/MOM_transcribe_grid.F90 | 6 ++ src/framework/MOM_dyn_horgrid.F90 | 9 +- src/initialization/MOM_grid_initialize.F90 | 6 ++ src/parameterizations/lateral/MOM_MEKE.F90 | 4 +- .../lateral/MOM_interface_filter.F90 | 4 +- .../lateral/MOM_lateral_mixing_coeffs.F90 | 99 ++----------------- .../lateral/MOM_mixed_layer_restrat.F90 | 12 +-- .../lateral/MOM_thickness_diffuse.F90 | 28 +++--- 10 files changed, 88 insertions(+), 127 deletions(-) diff --git a/src/core/MOM_grid.F90 b/src/core/MOM_grid.F90 index 384e4a6d2b..f3a48f3ded 100644 --- a/src/core/MOM_grid.F90 +++ b/src/core/MOM_grid.F90 @@ -90,6 +90,7 @@ module MOM_grid real ALLOCABLE_, dimension(NIMEMB_PTR_,NJMEM_) :: & mask2dCu, & !< 0 for boundary points and 1 for ocean points on the u grid [nondim]. + OBCmaskCu, & !< 0 for boundary or OBC points and 1 for ocean points on the u grid [nondim]. geoLatCu, & !< The geographic latitude at u points in degrees of latitude or m. geoLonCu, & !< The geographic longitude at u points in degrees of longitude or m. dxCu, & !< dxCu is delta x at u points [L ~> m]. @@ -102,6 +103,7 @@ module MOM_grid real ALLOCABLE_, dimension(NIMEM_,NJMEMB_PTR_) :: & mask2dCv, & !< 0 for boundary points and 1 for ocean points on the v grid [nondim]. + OBCmaskCv, & !< 0 for boundary or OBC points and 1 for ocean points on the v grid [nondim]. geoLatCv, & !< The geographic latitude at v points in degrees of latitude or m. geoLonCv, & !< The geographic longitude at v points in degrees of longitude or m. dxCv, & !< dxCv is delta x at v points [L ~> m]. @@ -573,7 +575,9 @@ subroutine allocate_metrics(G) ALLOC_(G%mask2dT(isd:ied,jsd:jed)) ; G%mask2dT(:,:) = 0.0 ALLOC_(G%mask2dCu(IsdB:IedB,jsd:jed)) ; G%mask2dCu(:,:) = 0.0 + ALLOC_(G%OBCmaskCu(IsdB:IedB,jsd:jed)) ; G%OBCmaskCu(:,:) = 0.0 ALLOC_(G%mask2dCv(isd:ied,JsdB:JedB)) ; G%mask2dCv(:,:) = 0.0 + ALLOC_(G%OBCmaskCv(isd:ied,JsdB:JedB)) ; G%OBCmaskCv(:,:) = 0.0 ALLOC_(G%mask2dBu(IsdB:IedB,JsdB:JedB)) ; G%mask2dBu(:,:) = 0.0 ALLOC_(G%geoLatT(isd:ied,jsd:jed)) ; G%geoLatT(:,:) = 0.0 ALLOC_(G%geoLatCu(IsdB:IedB,jsd:jed)) ; G%geoLatCu(:,:) = 0.0 @@ -637,8 +641,8 @@ subroutine MOM_grid_end(G) DEALLOC_(G%areaCu) ; DEALLOC_(G%IareaCu) DEALLOC_(G%areaCv) ; DEALLOC_(G%IareaCv) - DEALLOC_(G%mask2dT) ; DEALLOC_(G%mask2dCu) - DEALLOC_(G%mask2dCv) ; DEALLOC_(G%mask2dBu) + DEALLOC_(G%mask2dT) ; DEALLOC_(G%mask2dCu) ; DEALLOC_(G%OBCmaskCu) + DEALLOC_(G%mask2dCv) ; DEALLOC_(G%OBCmaskCv) ; DEALLOC_(G%mask2dBu) DEALLOC_(G%geoLatT) ; DEALLOC_(G%geoLatCu) DEALLOC_(G%geoLatCv) ; DEALLOC_(G%geoLatBu) @@ -686,6 +690,7 @@ end subroutine MOM_grid_end !! !!

The entire MOM_diag_vkernels.F90 file was then removed.

This change helps to address github.com/mom-ocean/MOM6/issues/769. Also added comments schematically describing some of the argument units. Because 0 was already being used for the missing value (except in unit tests), all solutions are bitwise identical. --- src/ALE/MOM_ALE.F90 | 6 +- src/ALE/MOM_remapping.F90 | 142 +++++++++--------- src/framework/MOM_diag_remap.F90 | 12 +- src/tracer/MOM_lateral_boundary_diffusion.F90 | 2 +- src/tracer/MOM_offline_aux.F90 | 1 - 5 files changed, 79 insertions(+), 84 deletions(-) diff --git a/src/ALE/MOM_ALE.F90 b/src/ALE/MOM_ALE.F90 index 5fd84c73c9..ec71e15bbd 100644 --- a/src/ALE/MOM_ALE.F90 +++ b/src/ALE/MOM_ALE.F90 @@ -536,7 +536,7 @@ subroutine ALE_offline_inputs(CS, G, GV, h, tv, Reg, uhtr, vhtr, Kd, debug, OBC) if (G%mask2dCu(i,j)>0.) then h_src(:) = 0.5 * (h(i,j,:) + h(i+1,j,:)) h_dest(:) = 0.5 * (h_new(i,j,:) + h_new(i+1,j,:)) - call reintegrate_column(nk, h_src, uhtr(I,j,:), nk, h_dest, 0., temp_vec) + call reintegrate_column(nk, h_src, uhtr(I,j,:), nk, h_dest, temp_vec) uhtr(I,j,:) = temp_vec endif enddo ; enddo @@ -544,7 +544,7 @@ subroutine ALE_offline_inputs(CS, G, GV, h, tv, Reg, uhtr, vhtr, Kd, debug, OBC) if (G%mask2dCv(i,j)>0.) then h_src(:) = 0.5 * (h(i,j,:) + h(i,j+1,:)) h_dest(:) = 0.5 * (h_new(i,j,:) + h_new(i,j+1,:)) - call reintegrate_column(nk, h_src, vhtr(I,j,:), nk, h_dest, 0., temp_vec) + call reintegrate_column(nk, h_src, vhtr(I,j,:), nk, h_dest, temp_vec) vhtr(I,j,:) = temp_vec endif enddo ; enddo @@ -554,7 +554,7 @@ subroutine ALE_offline_inputs(CS, G, GV, h, tv, Reg, uhtr, vhtr, Kd, debug, OBC) if (check_column_integrals(nk, h_src, nk, h_dest)) then call MOM_error(FATAL, "ALE_offline_inputs: Kd interpolation columns do not match") endif - call interpolate_column(nk, h(i,j,:), Kd(i,j,:), nk, h_new(i,j,:), 0., Kd(i,j,:)) + call interpolate_column(nk, h(i,j,:), Kd(i,j,:), nk, h_new(i,j,:), Kd(i,j,:)) endif enddo ; enddo diff --git a/src/ALE/MOM_remapping.F90 b/src/ALE/MOM_remapping.F90 index 20d3930d69..ad8fe48fbf 100644 --- a/src/ALE/MOM_remapping.F90 +++ b/src/ALE/MOM_remapping.F90 @@ -920,19 +920,19 @@ subroutine remap_via_sub_cells( n0, h0, u0, ppoly0_E, ppoly0_coefs, n1, h1, meth end subroutine remap_via_sub_cells !> Linearly interpolate interface data, u_src, from grid h_src to a grid h_dest -subroutine interpolate_column(nsrc, h_src, u_src, ndest, h_dest, missing_value, u_dest) - integer, intent(in) :: nsrc !< Number of source cells - real, dimension(nsrc), intent(in) :: h_src !< Thickness of source cells - real, dimension(nsrc+1), intent(in) :: u_src !< Values at source cell interfaces - integer, intent(in) :: ndest !< Number of destination cells - real, dimension(ndest), intent(in) :: h_dest !< Thickness of destination cells - real, intent(in) :: missing_value !< Value to assign in vanished cells - real, dimension(ndest+1), intent(inout) :: u_dest !< Interpolated value at destination cell interfaces +subroutine interpolate_column(nsrc, h_src, u_src, ndest, h_dest, u_dest) + integer, intent(in) :: nsrc !< Number of source cells + real, dimension(nsrc), intent(in) :: h_src !< Thickness of source cells [H] + real, dimension(nsrc+1), intent(in) :: u_src !< Values at source cell interfaces [A] + integer, intent(in) :: ndest !< Number of destination cells + real, dimension(ndest), intent(in) :: h_dest !< Thickness of destination cells [H] + real, dimension(ndest+1), intent(inout) :: u_dest !< Interpolated value at destination cell interfaces [A] + !

This meant that any error (e.g. layout) would show up as a fail of all types. We use the regression answers to check the repro-symmetric mode and then compare everything else to repro-symmetric or other results as appropriate. This allows us to distinguish between types of errors. The GH actions are doing it this way, and we originally did this in the first forms of the pipeline, but in the last re-factor I lazily switched to using the regression answers for everything. --- .gitlab-ci.yml | 243 +++++---------- .gitlab/README.md | 148 ++++++++++ .gitlab/mom6-ci-run-gnu-script.sh | 2 +- .gitlab/mom6-ci-run-intel-script.sh | 2 +- .gitlab/mom6-ci-run-pgi-script.sh | 2 +- .gitlab/pipeline-ci-tool.sh | 444 ++++++++++++++++++++++++++++ 6 files changed, 672 insertions(+), 169 deletions(-) create mode 100644 .gitlab/README.md create mode 100755 .gitlab/pipeline-ci-tool.sh diff --git a/.gitlab-ci.yml b/.gitlab-ci.yml index 496a578c91..6a622f55cc 100644 --- a/.gitlab-ci.yml +++ b/.gitlab-ci.yml @@ -6,124 +6,71 @@ stages: -

As with other netCDF tests, the nc-config tool is used if necessary (and available). This resolves some recent issues on platforms where netCDF and netCDF-Fortran are installed in separate locations, with different library directories (-L). It also resolves some false assumptions in configure.ac which presumed equivalent access by the configured C and Fortran compilers. Previously, we would test if the C compiler could be linked to netCDF, and then assume that the Fortran compiler shared the same relationship. We now use the Fortran compiler for both C and Fortran tests. This patch fixes many issues observed on MacOS systems, including some persistent problems on the GitHub Actions MacOS tests. For example, we can now use the default GCC 12 compilers, rather than forcing a rollback to GCC 11. --- .github/actions/macos-setup/action.yml | 2 +- .github/workflows/macos-regression.yml | 4 +-- .github/workflows/macos-stencil.yml | 4 +-- ac/configure.ac | 43 ++++++++++++------------ ac/m4/ax_fc_check_c_lib.m4 | 45 ++++++++++++++++++++++++++ 5 files changed, 70 insertions(+), 28 deletions(-) create mode 100644 ac/m4/ax_fc_check_c_lib.m4 diff --git a/.github/actions/macos-setup/action.yml b/.github/actions/macos-setup/action.yml index 197a2d83c8..fecbe787b5 100644 --- a/.github/actions/macos-setup/action.yml +++ b/.github/actions/macos-setup/action.yml @@ -10,7 +10,7 @@ runs: shell: bash run: | echo "::group::Install packages" - brew update + brew reinstall gcc brew install automake brew install netcdf brew install netcdf-fortran diff --git a/.github/workflows/macos-regression.yml b/.github/workflows/macos-regression.yml index d975854e0c..dc86a52212 100644 --- a/.github/workflows/macos-regression.yml +++ b/.github/workflows/macos-regression.yml @@ -8,8 +8,8 @@ jobs: runs-on: macOS-latest env: - CC: gcc-11 - FC: gfortran-11 + CC: gcc + FC: gfortran defaults: run: diff --git a/.github/workflows/macos-stencil.yml b/.github/workflows/macos-stencil.yml index 33436c221f..96240f31f8 100644 --- a/.github/workflows/macos-stencil.yml +++ b/.github/workflows/macos-stencil.yml @@ -8,8 +8,8 @@ jobs: runs-on: macOS-latest env: - CC: gcc-11 - FC: gfortran-11 + CC: gcc + FC: gfortran defaults: run: diff --git a/ac/configure.ac b/ac/configure.ac index 8d74d71fbd..58b05c7aaa 100644 --- a/ac/configure.ac +++ b/ac/configure.ac @@ -105,7 +105,7 @@ AX_FC_CHECK_MODULE([mpi], # netCDF configuration -# Search for the Fortran netCDF module, fallback to nf-config. +# Search for the Fortran netCDF module.

Specifically, some tests are using a C compiler which may be unconfigured, causing unexpected errors. The autoconf script now uses the Fortran compiler to test these bindings, rather than using the C compiler to test for their existence. A new macro (AX_FC_CHECK_BIND_C) was added to run these tests. This achieves the actual goal (test of Fortran binding) on top of the original goal (availability of C function), while ensuring that the actual compiler of interest (FC) is used in the test. Two C-based tests are still present in the script for testing the size of jmp_buf and sigjmp_buf. The C compiler is now configured with the AX_MPI macro, and is only used to determine the size of these structs. --- ac/configure.ac | 25 ++++++++++++++-------- ac/m4/ax_fc_check_bind_c.m4 | 42 +++++++++++++++++++++++++++++++++++++ ac/m4/ax_fc_check_c_lib.m4 | 6 +++--- 3 files changed, 61 insertions(+), 12 deletions(-) create mode 100644 ac/m4/ax_fc_check_bind_c.m4 diff --git a/ac/configure.ac b/ac/configure.ac index 58b05c7aaa..049325a891 100644 --- a/ac/configure.ac +++ b/ac/configure.ac @@ -88,8 +88,9 @@ AC_FC_SRCEXT(f90) # - This can cause standard AC_PROG_FC tests to fail if FCFLAGS is configured # with flags from another compiler. # - I do not yet know how to resolve this possible issue. -AX_MPI([], - [AC_MSG_ERROR([Could not find MPI launcher.])]) +AX_MPI([], [ + AC_MSG_ERROR([Could not find MPI launcher.]) +]) # Explicitly replace FC and LD with MPI wrappers @@ -233,13 +234,13 @@ AC_CONFIG_COMMANDS(Makefile.dep, [make depend]) # POSIX verification tests -AC_LANG_PUSH([C]) # These symbols may be defined as macros, making them inaccessible by Fortran. -# The following exist in BSD and Linux, so we just test for them. -AC_CHECK_FUNC([setjmp], [], [AC_MSG_ERROR([Could not find setjmp.])]) -AC_CHECK_FUNC([longjmp], [], [AC_MSG_ERROR([Could not find longjmp.])]) -AC_CHECK_FUNC([siglongjmp], [], [AC_MSG_ERROR([Could not find siglongjmp.])]) +# These three exist in modern BSD and Linux libc, so we just confirm them. +# But one day, we many need to handle them more carefully. +AX_FC_CHECK_BIND_C([setjmp], [], [AC_MSG_ERROR([Could not find setjmp.])]) +AX_FC_CHECK_BIND_C([longjmp], [], [AC_MSG_ERROR([Could not find longjmp.])]) +AX_FC_CHECK_BIND_C([siglongjmp], [], [AC_MSG_ERROR([Could not find siglongjmp.])]) # Determine the sigsetjmp symbol.

Rather, this update delegates such setup to mechanims used in ocean_BGS tracers leaving MOM6 mechanism for native tracers intact. - Fixed issues caught by MOM6 githubCI * Add capability to change obc segment update period - COBALT tracers do not need as frequent segment bc updates and can use a larger update period to speed up the model.

A new (char) parameter "ICE_VISCOSITY_COMPUTE" is introduced; its values can be "MODEL" (the ice viscosity computed by the model); "OBS" the ice viscosity is computed at the preprocessing step and read from a file (its name is defined by the parameter "ICE_STIFFNESS_FILE") into a variable with a name defined by "A_GLEN_VARNAME" parameter; "CONSANT" is a constant value defined by a parameter "A_GLEN". These changes are in MOM_ice_shelf_dynamics.F90. Minor changes are done to MOM_ice_shelf_initialize.F90 to correct units, scales. --- src/ice_shelf/MOM_ice_shelf_dynamics.F90 | 51 ++++++++++++++-------- src/ice_shelf/MOM_ice_shelf_initialize.F90 | 24 +++++----- 2 files changed, 45 insertions(+), 30 deletions(-) diff --git a/src/ice_shelf/MOM_ice_shelf_dynamics.F90 b/src/ice_shelf/MOM_ice_shelf_dynamics.F90 index 63ccc3d33c..e605f3e581 100644 --- a/src/ice_shelf/MOM_ice_shelf_dynamics.F90 +++ b/src/ice_shelf/MOM_ice_shelf_dynamics.F90 @@ -77,7 +77,8 @@ module MOM_ice_shelf_dynamics real, pointer, dimension(:,:) :: t_shelf => NULL() !< Vertically integrated temperature in the ice shelf/stream, !! on corner-points (B grid) [C ~> degC] real, pointer, dimension(:,:) :: tmask => NULL() !< A mask on tracer points that is 1 where there is ice. - real, pointer, dimension(:,:) :: ice_visc => NULL() !< Glen's law ice viscosity, often in [R L4 Z T-1 ~> kg m2 s-1]. + real, pointer, dimension(:,:) :: ice_visc => NULL() !< Glen's law ice viscosity (Pa s), + !! in [R L2 T-1 ~> kg m-1 s-1]. real, pointer, dimension(:,:) :: AGlen_visc => NULL() !< Ice-stiffness parameter in Glen's law ice viscosity, !! often in [kg-1/3 m-1/3 s-1]. real, pointer, dimension(:,:) :: thickness_bdry_val => NULL() !< The ice thickness at an inflowing boundary [Z ~> m]. @@ -94,7 +95,7 @@ module MOM_ice_shelf_dynamics !!

The LBD framework accounts for the effects of diabatic mesoscale fluxes -!! within surface and bottom boundary layers. Unlike the equivalent adiabatic -!! fluxes, which is applied along neutral density surfaces, LBD is purely -!! horizontal. To assure that diffusive fluxes are strictly horizontal -!! regardless of the vertical coordinate system, this method relies on -!! regridding/remapping techniques. -!! -!! The bottom boundary layer fluxes remain to be implemented, although some -!! of the steps needed to do so have already been added and tested. -!! -!! Boundary lateral diffusion is applied as follows: -!! -!! 1) remap tracer to a z* grid (LBD grid) -!! 2) calculate diffusive tracer fluxes (F) in the LBD grid using a layer by layer approach (@ref section_method) -!! 3) remap fluxes to the native grid -!! 4) update tracer by adding the divergence of F -!! -!! \subsection section_method Along layer approach -!! -!! Here diffusion is applied layer by layer using only information from neighboring cells. -!! -!! Step #1: define vertical grid using interfaces and surface boundary layers from left and right -!! columns (see merge_interfaces). -!! -!! Step #2: compute vertical indices containing boundary layer (boundary_k_range). -!! For the TOP boundary layer, these are: -!! -!! k_top, k_bot, zeta_top, zeta_bot -!! -!! Step #2: calculate the diffusive flux at each layer: -!! -!! \f[ F_{k} = -KHTR \times h_{eff}(k) \times (\phi_R(k) - \phi_L(k)), \f] -!! where h_eff is the [harmonic mean](@ref section_harmonic_mean) of the layer thickness -!! in the left and right columns. -!! -!! Step #3: option to linearly decay the flux from k_bot_min to k_bot_max: -!! -!! If LBD_LINEAR_TRANSITION = True and k_bot_diff > 1, the diffusive flux will decay -!! linearly between the top interface of the layer containing the minimum boundary -!! layer depth (k_bot_min) and the lower interface of the layer containing the -!! maximum layer depth (k_bot_max). -!! -!! Step #4: remap the fluxes back to the native grid. This is done at velocity points, whose vertical grid -!! is determined using [harmonic mean](@ref section_harmonic_mean).

This makes this module more computationaly efficient. A GMOM case run for 10 days and with 3 tracer is ~ 7.5 % faster. --- src/tracer/MOM_hor_bnd_diffusion.F90 | 1375 ++++++++++++++++++++++++++ 1 file changed, 1375 insertions(+) create mode 100644 src/tracer/MOM_hor_bnd_diffusion.F90 diff --git a/src/tracer/MOM_hor_bnd_diffusion.F90 b/src/tracer/MOM_hor_bnd_diffusion.F90 new file mode 100644 index 0000000000..4b9bd5ca40 --- /dev/null +++ b/src/tracer/MOM_hor_bnd_diffusion.F90 @@ -0,0 +1,1375 @@ +!> Calculates and applies diffusive fluxes as a parameterization of horizontal mixing (non-neutral) by +!! mesoscale eddies near the top and bottom (to be implemented) boundary layers of the ocean. + +module MOM_hor_bnd_diffusion + +!

The HBD framework accounts for the effects of diabatic mesoscale fluxes +!! within surface and bottom boundary layers. Unlike the equivalent adiabatic +!! fluxes, which is applied along neutral density surfaces, HBD is purely +!! horizontal. To assure that diffusive fluxes are strictly horizontal +!! regardless of the vertical coordinate system, this method relies on +!! regridding/remapping techniques. +!! +!! The bottom boundary layer fluxes remain to be implemented, although some +!! of the steps needed to do so have already been added and tested. +!! +!! Boundary lateral diffusion is applied as follows: +!! +!! 1) remap tracer to a z* grid (HBD grid) +!! 2) calculate diffusive tracer fluxes (F) in the HBD grid using a layer by layer approach (@ref section_method) +!! 3) remap fluxes to the native grid +!! 4) update tracer by adding the divergence of F +!! +!! \subsection section_method Along layer approach +!! +!! Here diffusion is applied layer by layer using only information from neighboring cells. +!! +!! Step #1: define vertical grid using interfaces and surface boundary layers from left and right +!! columns (see merge_interfaces). +!! +!! Step #2: compute vertical indices containing boundary layer (boundary_k_range). +!! For the TOP boundary layer, these are: +!! +!! k_top, k_bot, zeta_top, zeta_bot +!! +!! Step #2: calculate the diffusive flux at each layer: +!! +!! \f[ F_{k} = -KHTR \times h_{eff}(k) \times (\phi_R(k) - \phi_L(k)), \f] +!! where h_eff is the [harmonic mean](@ref section_harmonic_mean) of the layer thickness +!! in the left and right columns. +!! +!! Step #3: option to linearly decay the flux from k_bot_min to k_bot_max: +!! +!! If HBD_LINEAR_TRANSITION = True and k_bot_diff > 1, the diffusive flux will decay +!! linearly between the top interface of the layer containing the minimum boundary +!! layer depth (k_bot_min) and the lower interface of the layer containing the +!! maximum layer depth (k_bot_max). +!! +!! Step #4: remap the fluxes back to the native grid. This is done at velocity points, whose vertical grid +!! is determined using [harmonic mean](@ref section_harmonic_mean). To assure monotonicity, +!! tracer fluxes are limited so that 1) only down-gradient fluxes are applied, +!! and 2) the flux cannot be larger than F_max, which is defined using the tracer +!! gradient: +!! +!! \f[ F_{max} = -0.2 \times [(V_R(k) \times \phi_R(k)) - (V_L(k) \times \phi_L(k))], \f] +!! where V is the cell volume.

Also added two new runtime parameters, THICKNESS_IC_RESCALE and INTERFACE_IC_RESCALE, to allow input thickness and interface height fields to be rescaled. A number of spelling errors in comments or output messages in the files that were being modified as a part of this commit, including changes in the documentation that appears in MOM_parameter_doc files. All answers are bitwise identical, but there are new entries and minor changes in many MOM_parameter_doc files. --- src/ice_shelf/MOM_ice_shelf.F90 | 41 ++++---- .../MOM_coord_initialization.F90 | 20 ++-- .../MOM_state_initialization.F90 | 64 ++++++++---- src/ocean_data_assim/MOM_oda_driver.F90 | 16 +-- .../lateral/MOM_hor_visc.F90 | 33 ++++--- .../lateral/MOM_internal_tides.F90 | 98 +++++++------------ .../vertical/MOM_internal_tide_input.F90 | 17 +++- .../vertical/MOM_set_viscosity.F90 | 32 +++--- .../vertical/MOM_tidal_mixing.F90 | 66 ++++++++----- 9 files changed, 215 insertions(+), 172 deletions(-) diff --git a/src/ice_shelf/MOM_ice_shelf.F90 b/src/ice_shelf/MOM_ice_shelf.F90 index 26c74d73ec..1a29ef45e6 100644 --- a/src/ice_shelf/MOM_ice_shelf.F90 +++ b/src/ice_shelf/MOM_ice_shelf.F90 @@ -139,7 +139,7 @@ module MOM_ice_shelf real :: time_step !< this is the shortest timestep that the ice shelf sees [T ~> s], and !! is equal to the forcing timestep (it is passed in when the shelf !! is initialized - so need to reorganize MOM driver. - !! it will be the prognistic timestep ... maybe. + !! it will be the prognostic timestep ... maybe. logical :: solo_ice_sheet !< whether the ice model is running without being !! coupled to the ocean @@ -288,13 +288,13 @@ subroutine shelf_calc_flux(sfc_state_in, fluxes_in, Time, time_step_in, CS) real :: n_star_term !

This commit will change answers when INT_TIDE_DISSIPATION = True, USE_CVMix_TIDAL = True, and TIDAL_ENERGY_TYPE = "ER03". There are no such configurations in the MOM6-examples pipeline tests, and it is not clear whether or where such a configuration has ever been used. This bug was introduced into dev/gfdl on Nov. 19, 2018 as a part of PR #883 in commit https://github.com/NOAA-GFDL/MOM6/commit/967e470, which was supposed to be a refactoring of this portion of the code without changing answers, but introduced this bug.

The Python scripts have been replaced with equivalent Fortran programs which generate identical netCDF output. A new rule (`preproc`) has been added to the .testing top Makefile for generating the model input files. The netCDF compiler dependenices are configured with autoconf, currently duplicating the macros in `ac/configure.ac`. (NOTE: It may be possible to share these with a common macro in ac/m4. The configure script and Makefile are currently generated from `configure.ac` and `autoreconf`. In the future, we could simply pre-generate `configure` and add it to the repository. This patch was motivated by the inability to install recent netCDF-Python packages on systems with older gcc compilers, including our main production machine. We could have possibly resolved this by adding compiler configuration to pip, or perhaps reported the issue to the netCDF-python project for them to resolve. But the costs of relying on all this Python infrastructure is starting to exceed the benefits, and I would recommend we excise it from our test suite. --- .github/actions/testing-setup/action.yml | 12 -- .github/workflows/coupled-api.yml | 1 - .testing/Makefile | 91 ++++------- .testing/tc4/.gitignore | 13 +- .testing/tc4/Makefile | 8 - .testing/tc4/Makefile.in | 38 +++++ .testing/tc4/build_data.py | 80 ---------- .testing/tc4/build_grid.py | 76 --------- .testing/tc4/configure.ac | 71 +++++++++ .testing/tc4/gen_data.F90 | 189 +++++++++++++++++++++++ .testing/tc4/gen_grid.F90 | 108 +++++++++++++ 11 files changed, 448 insertions(+), 239 deletions(-) delete mode 100644 .testing/tc4/Makefile create mode 100644 .testing/tc4/Makefile.in delete mode 100644 .testing/tc4/build_data.py delete mode 100644 .testing/tc4/build_grid.py create mode 100644 .testing/tc4/configure.ac create mode 100644 .testing/tc4/gen_data.F90 create mode 100644 .testing/tc4/gen_grid.F90 diff --git a/.github/actions/testing-setup/action.yml b/.github/actions/testing-setup/action.yml index 8a3264b140..6ba149d927 100644 --- a/.github/actions/testing-setup/action.yml +++ b/.github/actions/testing-setup/action.yml @@ -5,10 +5,6 @@ inputs: description: 'If true, will build the symmetric MOM6 executable' required: false default: 'true' - install_python: - description: 'If true, will install the local python env needed for .testing' - required: false - default: 'true' runs: using: 'composite' steps: @@ -54,14 +50,6 @@ runs: test ${{ inputs.build_symmetric }} == true && make build/symmetric/MOM6 -j echo "::endgroup::" - - name: Install local python venv for generating input data - shell: bash - run: | - echo "::group::Create local python env for input data generation" - cd .testing - test ${{ inputs.install_python }} == true && make work/local-env - echo "::endgroup::" - - name: Set flags shell: bash run: | diff --git a/.github/workflows/coupled-api.yml b/.github/workflows/coupled-api.yml index 443755c7f4..2c9fa32720 100644 --- a/.github/workflows/coupled-api.yml +++ b/.github/workflows/coupled-api.yml @@ -20,7 +20,6 @@ jobs: - uses: ./.github/actions/testing-setup with: build_symmetric: 'false' - install_python: 'false' - name: Compile MOM6 for the GFDL coupled driver shell: bash diff --git a/.testing/Makefile b/.testing/Makefile index 530a552181..3e5c174239 100644 --- a/.testing/Makefile +++ b/.testing/Makefile @@ -11,7 +11,7 @@ # Delete the MOM6 test executables and dependency builds (FMS) # # make clean.build -# Delete only the MOM6 test executables +# Delete only the MOM6 test executables # # # Configuration: @@ -204,34 +204,11 @@ endif FMS_SOURCE = $(call SOURCE,deps/fms/src) -#--- -# Python preprocessing environment configuration - -HAS_NUMPY = $(shell python -c "import numpy" 2> /dev/null && echo "yes") -HAS_NETCDF4 = $(shell python -c "import netCDF4" 2> /dev/null && echo "yes") - -USE_VENV = -ifneq ($(HAS_NUMPY), yes) - USE_VENV = yes -endif -ifneq ($(HAS_NETCDF4), yes) - USE_VENV = yes -endif - -# When disabled, activation is a null operation (`true`) -VENV_PATH = -VENV_ACTIVATE = true -ifeq ($(USE_VENV), yes) - VENV_PATH = work/local-env - VENV_ACTIVATE = . $(VENV_PATH)/bin/activate -endif - - #--- # Rules .PHONY: all build.regressions build.prof -all: $(foreach b,$(BUILDS),build/$(b)) $(VENV_PATH) +all: $(foreach b,$(BUILDS),build/$(b)) build.regressions: $(foreach b,symmetric target,build/$(b)/MOM6) build.prof: $(foreach b,opt opt_target,build/$(b)/MOM6) @@ -382,8 +359,8 @@ deps/Makefile: ../ac/deps/Makefile # broken the ability to compile.

The rule has since been removed, and the command now fails. This patch removes those steps, since we no longer use Python in the tests. It also slightly reworks the reporting of test output. Instead of re-running `make test`, it uses the `make test.summary` rule to report the final result. --- .gitlab-ci.yml | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) diff --git a/.gitlab-ci.yml b/.gitlab-ci.yml index 6a622f55cc..fbc2854b33 100644 --- a/.gitlab-ci.yml +++ b/.gitlab-ci.yml @@ -26,7 +26,7 @@ p:merge: # Setup the persistent JOB_DIR for all subsequent stages # -# This basically setups up a complete tree much as a user would in their workflow +# This basically setups up a complete tree much as a user would in their workflow p:clone: stage: setup tags: @@ -181,11 +181,11 @@ actions:gnu: - echo -e "\e[0Ksection_start:`date +%s`:compile[collapsed=true]\r\e[0KCompiling executables" - cd .testing - module unload PrgEnv-pgi PrgEnv-intel PrgEnv-gnu darshan ; module load PrgEnv-gnu ; module unload netcdf gcc ; module load gcc/7.3.0 cray-hdf5 cray-netcdf - - make work/local-env - make -s -j - echo -e "\e[0Ksection_end:`date +%s`:compile\r\e[0K" - - (echo '#!/bin/bash';echo '. ./work/local-env/bin/activate';echo 'make MPIRUN="srun -mblock --exclusive" test -s -j') > job.sh - - sbatch --clusters=c3,c4 --nodes=5 --time=0:05:00 --account=gfdl_o --qos=debug --job-name=MOM6.gnu.testing --output=log.$CI_JOB_ID --wait job.sh && make test || ( cat log.$CI_JOB_ID ; exit 911 ) + - (echo '#!/bin/bash';echo 'make MPIRUN="srun -mblock --exclusive" test -s -j') > job.sh + - sbatch --clusters=c3,c4 --nodes=5 --time=0:05:00 --account=gfdl_o --qos=debug --job-name=MOM6.gnu.testing --output=log.$CI_JOB_ID --wait job.sh || ( cat log.$CI_JOB_ID ; exit 911 ) + - make test.summary actions:intel: stage: tests @@ -200,11 +200,11 @@ actions:intel: - echo -e "\e[0Ksection_start:`date +%s`:compile[collapsed=true]\r\e[0KCompiling executables" - cd .testing - module unload PrgEnv-pgi PrgEnv-intel PrgEnv-gnu darshan; module load PrgEnv-intel; module unload netcdf intel; module load intel/18.0.6.288 cray-hdf5 cray-netcdf - - make work/local-env - make -s -j - echo -e "\e[0Ksection_end:`date +%s`:compile\r\e[0K" - - (echo '#!/bin/bash';echo '. ./work/local-env/bin/activate';echo 'make MPIRUN="srun -mblock --exclusive" test -s -j') > job.sh - - sbatch --clusters=c3,c4 --nodes=5 --time=0:05:00 --account=gfdl_o --qos=debug --job-name=MOM6.intel.testing --output=log.$CI_JOB_ID --wait job.sh && make test || ( cat log.$CI_JOB_ID ; exit 911 ) + - (echo '#!/bin/bash';echo 'make MPIRUN="srun -mblock --exclusive" test -s -j') > job.sh + - sbatch --clusters=c3,c4 --nodes=5 --time=0:05:00 --account=gfdl_o --qos=debug --job-name=MOM6.intel.testing --output=log.$CI_JOB_ID --wait job.sh || ( cat log.$CI_JOB_ID ; exit 911 ) + - make test.summary # Tests # From b918b2ad5907a866ec27ea7888db606b1ff79774 Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Tue, 25 Oct 2022 12:17:27 -0400 Subject: [PATCH 0466/1329] +Add mask_edges argument to interpolate_column Added a new logical argument to interpolate_column to specify whether the interpolated interface values outside of massless layers should be masked to zero.

Also added the new routines remap_dyn_split_rk2_aux_vars, remap_OBC_fields and remap_vertvisc_aux_vars to do the remapping, and code to call these routines when REMAP_AUXILIARY_VARS is true. By default, REMAP_AUXILIARY_VARS is false, and all answers are bitwise identical, but the entire MOM6-examples regression suite has been run with this set to true, and they do appear to give physically plausible answers in all cases, partially addressing the issue noted at github.com/NOAA-GFDL/MOM6/issues/203.

The variable set by DENSE_WATER_SILL_HEIGHT was unused and it probably was always intended to be DENSE_WATER_SILL_DEPTH, which it now is. Units arguments were also added to two of the unlogged get_param calls in this module. Without this change, this test case would not reproduce with dimensional rescaling due to a scale factor that was omitted when salinity was being rescaled on May 3, 2022, which became a part of PR #122 to dev/gfdl, but answers should not change when dimensional rescaling of salinities is not used.

This has been replaced with the recommended solution for handling concurrent outputs: use one to generate both, and connect the second to the first with a separate rule.

In testing both via the TC tests and the MOM6-examples regression suite, all answers are bitwise identical, because every instance where these are used either does have an appropriate call to the initialization routine, or because (as is the case for remapping diagnostics) they are hard-coded to use the PLM remapping scheme, which is not impacted by this answer_date. It is conceivable, if unlikely, however, that there could be cases outside of the standard MOM6 code that are using this remapping capability without proper initialization of this flag, in which case answers could change. In addition, a comment was updated in the interp_CS_type indicating the cases that would be altered by changing the hard coded default answer_date there, but the default in that case was not changed. All answers and output are identical in the MOM6-examples and TC test suites. --- src/ALE/MOM_regridding.F90 | 2 +- src/ALE/MOM_remapping.F90 | 2 +- src/ALE/regrid_interp.F90 | 3 ++- src/diagnostics/MOM_wave_speed.F90 | 9 ++++----- 4 files changed, 8 insertions(+), 8 deletions(-) diff --git a/src/ALE/MOM_regridding.F90 b/src/ALE/MOM_regridding.F90 index de287af98a..27dd1ab4d5 100644 --- a/src/ALE/MOM_regridding.F90 +++ b/src/ALE/MOM_regridding.F90 @@ -120,7 +120,7 @@ module MOM_regridding !> The vintage of the order of arithmetic and expressions to use for remapping. !!

The BFB module was more extensively modified to place logging of the module name and version before the get_param calls for this module, following the MOM6 pattern, to correct spelling errors in get_param descriptions, and to use the grid mask in the grid file rather than a reexamination of the minimum depth to determine the land-mask. The internal subroutine write_BFB_log is no longer needed and has been folded into BFB_set_coord. All answers are bitwise identical, but there are minor changes in the MOM_parameter_doc files for the buoy_forced_basin test case. --- src/user/BFB_initialization.F90 | 68 +++++++----------- src/user/BFB_surface_forcing.F90 | 4 +- src/user/Rossby_front_2d_initialization.F90 | 80 ++++++++++++--------- 3 files changed, 72 insertions(+), 80 deletions(-) diff --git a/src/user/BFB_initialization.F90 b/src/user/BFB_initialization.F90 index 68a6b6530b..3efc908ffb 100644 --- a/src/user/BFB_initialization.F90 +++ b/src/user/BFB_initialization.F90 @@ -24,10 +24,6 @@ module BFB_initialization ! their mks counterparts with notation like "a velocity [Z T-1 ~> m s-1]".

They are currently configured to run in the same directory. Recently, several unusual I/O errors suggest problems due to concurrent testing of the builds. In order to rule out this possibility, this patch moves the ice-ocean test to a separate directory. --- .gitlab/pipeline-ci-tool.sh | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/.gitlab/pipeline-ci-tool.sh b/.gitlab/pipeline-ci-tool.sh index e23d64523d..8334bd3950 100755 --- a/.gitlab/pipeline-ci-tool.sh +++ b/.gitlab/pipeline-ci-tool.sh @@ -151,8 +151,8 @@ nolibs-ocean-ice-compile () { section-start nolibs-ocean-ice-compile-$1 "Compiling ocean-ice $1 executable" if [ ! $DRYRUN ] ; then cd $JOB_DIR/$STATS_REPO_DIR/$CONFIGS_DIR - mkdir -p build-ocean-only-nolibs-$1 - cd build-ocean-only-nolibs-$1 + mkdir -p build-ocean-ice-nolibs-$1 + cd build-ocean-ice-nolibs-$1 make -f ../tools/MRS/Makefile.build ./$1/env BUILD=. -s ../src/mkmf/bin/list_paths -l ../src/MOM6/config_src/{drivers/FMS_cap,memory/dynamic_symmetric,infra/FMS1,ext*} ../src/MOM6/src ../src/SIS2/*src ../src/{FMS1,coupler,icebergs,ice_param,land_null,atmos_null} sed -i '/FMS1\/.*\/test_/d' path_names From 7055b7cf2c46f2e30c9e13e9d0d7fadfe7235a8d Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Wed, 23 Nov 2022 08:22:48 -0500 Subject: [PATCH 0481/1329] Document units in 9 vertical param modules Documented numerous internal variables and their units in 9 vertical parameterization modules (MOM_bkgnd_mixing, MOM_bulk_mixed_layer, MOM_diabatic_aux, MOM_diabatic_driver, MOM_entrain_diffusive, MOM_kappa_shear, MOM_regularize_layers, MOM_set_diffusivity and MOM_set_viscosity).

With a grid construction that is symmetric about the equator, this term is also exactly zero, leading to a division by zero. To avoid this, a very small minimum ustar value is introduced, using the Earth's rotation as a velocity timescale, in the same manner as in some of the vertical parameterisations. This should prevent the denominator of the momentum mixing rate from going to zero. --- .../lateral/MOM_mixed_layer_restrat.F90 | 17 +++++++++++++---- 1 file changed, 13 insertions(+), 4 deletions(-) diff --git a/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 b/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 index 0aef33ddc6..506046340d 100644 --- a/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 +++ b/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 @@ -61,6 +61,7 @@ module MOM_mixed_layer_restrat type(diag_ctrl), pointer :: diag !< A structure that is used to regulate the !! timing of diagnostic output. logical :: use_stanley_ml !< If true, use the Stanley parameterization of SGS T variance + real :: omega !< The Earth's rotation rate [T-1 ~> s-1]. real, dimension(:,:), allocatable :: & MLD_filtered, & !< Time-filtered MLD [H ~> m or kg m-2] @@ -160,6 +161,7 @@ subroutine mixedlayer_restrat_general(h, uhtr, vhtr, tv, forces, dt, MLD_in, Var real :: h_min !

"externals" are always compiled, in lieu of flinting the source code. This commit simply adds all the C object files to the list of externals. When building a library, the module dependencies are ignore and everything gets built, which is why this gap was not seen before. --- ac/makedep | 1 + 1 file changed, 1 insertion(+) diff --git a/ac/makedep b/ac/makedep index d201b49ab2..829928626b 100755 --- a/ac/makedep +++ b/ac/makedep @@ -92,6 +92,7 @@ def create_deps(src_dirs, makefile, debug, exec_target, fc_rule, _, _, cpp, inc, _ = scan_fortran_file(f) # maps object file to .h files included o2h[object_file(f)] = cpp + externals.append(object_file(f)) # Are we building a library, single or multiple executables? targ_libs = [] From 9bc8772afb4c8a11a829c351824dfd431d7a14ce Mon Sep 17 00:00:00 2001 From: Alistair Adcroft Date: Fri, 9 Dec 2022 14:05:37 -0500 Subject: [PATCH 0487/1329] makedep: PEP8 cleanup Fixes all remaining PEP8 violations in ac/makedep (using line length = 132). --- ac/makedep | 36 ++++++++++++++++++------------------ 1 file changed, 18 insertions(+), 18 deletions(-) diff --git a/ac/makedep b/ac/makedep index 829928626b..5954f1aae5 100755 --- a/ac/makedep +++ b/ac/makedep @@ -74,14 +74,14 @@ def create_deps(src_dirs, makefile, debug, exec_target, fc_rule, if prg: for p in prg: if p in prg2o.keys(): -

The resulting expressions for ustar_min therefore effectively have units of [Z s T-2 ~> m s-1] when they should have units of [Z T-1 ~> m s-1]. Because ustar_min is a tiny floor on the magnitude of ustar, there is a range of values of T_RESCALE_POWER that will give the same answers as when it is 0, but for large enough values the answers will change, perhaps dramatically. This small commit removes these extra factors. Answers will change for some large values of T_RESCALE_POWER, but they are bitwise identical in the TC testing and in MOM6-examples based regression tests with modest or negative values. --- .../lateral/MOM_mixed_layer_restrat.F90 | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-) diff --git a/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 b/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 index 506046340d..102e2723aa 100644 --- a/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 +++ b/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 @@ -309,7 +309,7 @@ subroutine mixedlayer_restrat_general(h, uhtr, vhtr, tv, forces, dt, MLD_in, Var g_Rho0 = GV%g_Earth / GV%Rho0 h_neglect = GV%H_subroundoff dz_neglect = GV%H_subroundoff*GV%H_to_Z - ustar_min = 2e-4 * CS%omega * US%T_to_S * (GV%Angstrom_Z + dz_neglect) + ustar_min = 2e-4 * CS%omega * (GV%Angstrom_Z + dz_neglect) if (CS%front_length>0.) then res_upscale = .true.

Once this PR is merged onto the main branch of MOM6, that issue can be closed. By default, these do not change answers in the MOM6-examples test suite, but the default value for RESTRAT_USTAR_MIN was taken from the hard-coded value in PR that PR. The six copies of the eddy growth rate timescale calculations were consolidated into a new internal function, growth_time, with some other related minor refactoring of the code. Also, mixedlayer_restrat_register_restarts now takes a unit_scale_type arguments like many other analogous routines. All answers are bitwise identical, but there are new runtime parameters or comments that lead to changes in the MOM_parameter_doc files. Also clarified in the comments sent to the MOM_parameter_doc files how VISBECK_L_SCALE works as a dimensional scaling factor when it is given a negative value, and rescaled its units when read as though it were always in m. --- src/core/MOM.F90 | 16 +- .../lateral/MOM_lateral_mixing_coeffs.F90 | 20 +- .../lateral/MOM_mixed_layer_restrat.F90 | 201 ++++++++++-------- 3 files changed, 126 insertions(+), 111 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 6c978b36f5..d1fd8619da 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -2219,11 +2219,10 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, restart_CSp, & "A tiny magnitude of temperatures below which they are set to 0.", & units="degC", default=0.0, scale=US%degC_to_C) call get_param(param_file, "MOM", "C_P", CS%tv%C_p, & - "The heat capacity of sea water, approximated as a "//& - "constant.

Also corrected the dimensional rescaling of dSVdT and dSVdS in calc_spec_vol_derivs_1d when temperature and salinity are being rescaled but density is not. Fortunately these do not seem to impact solutions in any production runs, and there do not appear to be any calls to calculate_density_second_derivs_scalar(). Also added checksum calls for tv%varT, tv%varS and tv%covarTS to MOM_thermo_chksum when these elements of the thermovar type are associated. Comments were also added describing the units of a number of internal variables or conversion factor in the MOM_EOS module. All answers in the MOM6-examples test suite are bitwise identical. --- src/core/MOM_checksum_packages.F90 | 6 ++- src/equation_of_state/MOM_EOS.F90 | 65 ++++++++++++++++++++---------- 2 files changed, 48 insertions(+), 23 deletions(-) diff --git a/src/core/MOM_checksum_packages.F90 b/src/core/MOM_checksum_packages.F90 index aa080e1e8e..871de51632 100644 --- a/src/core/MOM_checksum_packages.F90 +++ b/src/core/MOM_checksum_packages.F90 @@ -92,7 +92,7 @@ subroutine MOM_state_chksum_3arg(mesg, u, v, h, G, GV, US, haloshift, symmetric) intent(in) :: v !< Meridional velocity [L T-1 ~> m s-1] or [m s-1].. real, dimension(SZI_(G),SZJ_(G),SZK_(GV)), & intent(in) :: h !< Layer thicknesses [H ~> m or kg m-2]. - type(unit_scale_type), intent(in) :: US !< A dimensional unit scaling type, which is + type(unit_scale_type), intent(in) :: US !< A dimensional unit scaling type, which is !! used to rescale u and v if present. integer, optional, intent(in) :: haloshift !< The width of halos to check (default 0). logical, optional, intent(in) :: symmetric !< If true, do checksums on the fully @@ -130,6 +130,10 @@ subroutine MOM_thermo_chksum(mesg, tv, G, US, haloshift) scale=US%Q_to_J_kg*US%R_to_kg_m3*US%Z_to_m) if (associated(tv%salt_deficit)) call hchksum(tv%salt_deficit, mesg//" salt deficit", G%HI, haloshift=hs, & scale=US%S_to_ppt*US%RZ_to_kg_m2) + if (associated(tv%varT)) call hchksum(tv%varT, mesg//" varT", G%HI, haloshift=hs, scale=US%C_to_degC**2) + if (associated(tv%varS)) call hchksum(tv%varS, mesg//" varS", G%HI, haloshift=hs, scale=US%S_to_ppt**2) + if (associated(tv%covarTS)) call hchksum(tv%covarTS, mesg//" covarTS", G%HI, haloshift=hs, & + scale=US%S_to_ppt*US%C_to_degC) end subroutine MOM_thermo_chksum diff --git a/src/equation_of_state/MOM_EOS.F90 b/src/equation_of_state/MOM_EOS.F90 index c946ddaff8..27484aa536 100644 --- a/src/equation_of_state/MOM_EOS.F90 +++ b/src/equation_of_state/MOM_EOS.F90 @@ -126,16 +126,18 @@ module MOM_EOS real :: dTFr_dp !< The derivative of freezing point with pressure [degC Pa-1] !

There was also extensive refactoring of the MOM_stoch_eos.F90 code. Specifically this commit makes the following changes: - The new routine stoch_eos_register_restarts was added to register the restart field associated with the MOM_stoch_EOS module before the restarts are read and before restart_registry_lock is called, which was causing any test case with STOCH_EOS=True or a positive value of STANLEY_COEF to have a fatal error. - Added a missing dimensional rescaling factor in the get_param call for KD_SMOOTH in MOM_stoch_eos_init, which would have caused cases exercising the MOM_stoch_eos options to fail the dimensional consistency tests. - MOM_stoch_eos_init was changed from a subroutine into a function that returns a logical value indicating whether this routine is used further. The order of the arguments was modified to match the order used in every other init call. - The new routine post_stoch_eos_diags was added to write diagnostics associated with the stoch_eos module. - The MOM_stoch_eos_CS type was made opaque. - The unused diag argument was removed from MOM_stoch_eos_run. - Unit arguments were added to the get_param calls for STANLEY_COEFF and STANLEY_A. - Four arrays in the MOM_stoch_eos_CS type that had been declared to optionally use static memory allocation were modified to be simple allocatables, as they are not used in the vast majority of MOM6 cases, and there is no reason to always assign memory to them. - The register_restart_field call for "stoch_eos_pattern" was revised to use the newer, more direct form rather than working via a vardesc type. - Return statements were added to several of the MOM_stoch_eos routines in the cases where they are not supposed to do anything. - The comments describing several real variables in the MOM_stoch_eos module were added or modified to describe their units using the standard format. - The module use statements at the start of the MOM_stoch_eos module were updated to reflect these changes. There were also parallel changes in MOM.F90: - Added use_stochastic_EOS element to the MOM_control_struct to indicate whether the stoch_eos calls are to be used. - MOM_stoch_eos_init is only called if temperature and salinities are state variables, as it makes no sense to call it otherwise. - Calls to stoch_eos routines were updates to reflect the new interfaces. - The contents of the MOM_stoch_eos_CS type are no longer used in MOM.F90. All answers are bitwise identical in cases that do not use dimensional rescaling, but answers will change (be corrected) in some cases that do use dimensional consistency tests. Several public interfaces to MOM_stoch_eos routines were altered, and there are changes to multiple MOM_parameter_doc files due to the new units, and due to the fact that stoch_EOS parameters are no longer being logged in cases where they are meaningless. --- src/core/MOM.F90 | 26 +++-- src/core/MOM_stoch_eos.F90 | 191 ++++++++++++++++++++++--------------- 2 files changed, 132 insertions(+), 85 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index d1fd8619da..8d7caf83ed 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -114,7 +114,8 @@ module MOM use MOM_shared_initialization, only : write_ocean_geometry_file use MOM_sponge, only : init_sponge_diags, sponge_CS use MOM_state_initialization, only : MOM_initialize_state -use MOM_stoch_eos, only : MOM_stoch_eos_init,MOM_stoch_eos_run,MOM_stoch_eos_CS,mom_calc_varT +use MOM_stoch_eos, only : MOM_stoch_eos_init, MOM_stoch_eos_run, MOM_stoch_eos_CS +use MOM_stoch_eos, only : stoch_EOS_register_restarts, post_stoch_EOS_diags, mom_calc_varT use MOM_sum_output, only : write_energy, accumulate_net_input use MOM_sum_output, only : MOM_sum_output_init, MOM_sum_output_end use MOM_sum_output, only : sum_output_CS @@ -288,6 +289,7 @@ module MOM logical :: thickness_diffuse_first !< If true, diffuse thickness before dynamics. logical :: mixedlayer_restrat !< If true, use submesoscale mixed layer restratifying scheme. logical :: useMEKE !< If true, call the MEKE parameterization. + logical :: use_stochastic_EOS !< If true, use the stochastic EOS parameterizations. logical :: useWaves !< If true, update Stokes drift logical :: use_p_surf_in_EOS !< If true, always include the surface pressure contributions !! in equation of state calculations. @@ -1079,12 +1081,12 @@ subroutine step_MOM_dynamics(forces, p_surf_begin, p_surf_end, dt, dt_thermo, & call cpu_clock_begin(id_clock_dynamics) call cpu_clock_begin(id_clock_stoch) - if (CS%stoch_eos_CS%use_stoch_eos) call MOM_stoch_eos_run(G,u,v,dt,Time_local,CS%stoch_eos_CS,CS%diag) + if (CS%use_stochastic_EOS) call MOM_stoch_eos_run(G, u, v, dt, Time_local, CS%stoch_eos_CS) call cpu_clock_end(id_clock_stoch) call cpu_clock_begin(id_clock_varT) - if (CS%stoch_eos_CS%stanley_coeff >= 0.0) then - call MOM_calc_varT(G,GV,h,CS%tv,CS%stoch_eos_CS,dt) - call pass_var(CS%tv%varT, G%Domain,clock=id_clock_pass,halo=1) + if (CS%use_stochastic_EOS) then + call MOM_calc_varT(G, GV, h, CS%tv, CS%stoch_eos_CS, dt) + if (associated(CS%tv%varT)) call pass_var(CS%tv%varT, G%Domain, clock=id_clock_pass, halo=1) endif call cpu_clock_end(id_clock_varT) @@ -1297,9 +1299,7 @@ subroutine step_MOM_dynamics(forces, p_surf_begin, p_surf_end, dt, dt_thermo, & if (IDs%id_u > 0) call post_data(IDs%id_u, u, CS%diag) if (IDs%id_v > 0) call post_data(IDs%id_v, v, CS%diag) if (IDs%id_h > 0) call post_data(IDs%id_h, h, CS%diag) - if (CS%stoch_eos_CS%id_stoch_eos > 0) call post_data(CS%stoch_eos_CS%id_stoch_eos, CS%stoch_eos_CS%pattern, CS%diag) - if (CS%stoch_eos_CS%id_stoch_phi > 0) call post_data(CS%stoch_eos_CS%id_stoch_phi, CS%stoch_eos_CS%phi, CS%diag) - if (CS%stoch_eos_CS%id_tvar_sgs > 0) call post_data(CS%stoch_eos_CS%id_tvar_sgs, CS%tv%varT, CS%diag) + if (CS%use_stochastic_EOS) call post_stoch_EOS_diags(CS%stoch_eos_CS, CS%tv, CS%diag) call disable_averaging(CS%diag) call cpu_clock_end(id_clock_diagnostics) ; call cpu_clock_end(id_clock_other) @@ -2679,6 +2679,10 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, restart_CSp, & call waves_register_restarts(waves_CSp, HI, GV, param_file, restart_CSp) endif + if (use_temperature) then + call stoch_EOS_register_restarts(HI, param_file, CS%stoch_eos_CS, restart_CSp) + endif + call callTree_waypoint("restart registration complete (initialize_MOM)") call restart_registry_lock(restart_CSp) @@ -2964,7 +2968,11 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, restart_CSp, & call interface_filter_init(Time, G, GV, US, param_file, diag, CS%CDp, CS%interface_filter_CSp) new_sim = is_new_run(restart_CSp) - call MOM_stoch_eos_init(G,Time,param_file,CS%stoch_eos_CS,restart_CSp,diag) + if (use_temperature) then + CS%use_stochastic_EOS = MOM_stoch_eos_init(Time, G, US, param_file, diag, CS%stoch_eos_CS, restart_CSp) + else + CS%use_stochastic_EOS = .false. + endif if (CS%use_porbar) & call porous_barriers_init(Time, US, param_file, diag, CS%por_bar_CS) diff --git a/src/core/MOM_stoch_eos.F90 b/src/core/MOM_stoch_eos.F90 index 2f67077f1e..deb878e99c 100644 --- a/src/core/MOM_stoch_eos.F90 +++ b/src/core/MOM_stoch_eos.F90 @@ -2,46 +2,44 @@ module MOM_stoch_eos !

These bugs were accidentally introduced when the changes adding the MOM_stoch_eos code to the main branch of MOM6 were merged with changes on the dev/gfdl branch. Also added a test for cases when USE_STANLEY_GM is set to true but STANLEY_COEF is negative to reset the internal versions of this flag to false with a sensible warning message rather than encountering segmentation faults. All solutions are bitwise identical in cases that worked before. --- src/core/MOM_isopycnal_slopes.F90 | 92 +++++++++---------- .../lateral/MOM_thickness_diffuse.F90 | 38 +++++--- 2 files changed, 71 insertions(+), 59 deletions(-) diff --git a/src/core/MOM_isopycnal_slopes.F90 b/src/core/MOM_isopycnal_slopes.F90 index b5bd51d75a..07dd19b0a6 100644 --- a/src/core/MOM_isopycnal_slopes.F90 +++ b/src/core/MOM_isopycnal_slopes.F90 @@ -3,12 +3,12 @@ module MOM_isopycnal_slopes !

Also use elements of the ocean_grid_type to specify the units of some horizontal position related variables and to determine the domain size, rather than using separate get_param calls for LENLAT or LENLAT. This commit also adds comments describing many internal real variables and their units in RGC_tracer.F90.

The `siglongjmp` interface was referencing the wrong symbol (`longjmp`). While this did not seem to cause any issues, possibly due to some shared definitions on glibc/BSD platforms, the error was correctly detected by the Cray compiler. This patch corrects the C symbol name. The `sigsetjmp_missing` function, as a default replacement for a missing `sigsetjmp`, was also defined without a return value, since it always returns an error if called at runtime. The Cray compiler raised a warning about this, so we now assign a return value of -1, although it is never used.

This vertical viscosity scheme redistributes momentum in the vertical, and is the equivalent of the Gent & McWilliams (1990) parameterization, but in a TWA (thickness-weighted averaged) set of equations. The vertical viscosity coefficient nu is computed from kappa_GM via thermal wind balance, and the following relation: nu = kappa_GM * f^2 / N^2. The vertical viscosity del_z ( nu del_z u) is applied to the momentum equation with stress-free boundary conditions at the top and bottom. In the current implementation, kappa_GM is assumed either (a) constant or as (b) having an EBT structure. A third possible formulation of nu is depth-independent: nu = f^2 * alpha The latter formulation would be equivalent to a kappa_GM that varies as N^2 with depth. Currently, the GL90 parameterization is only implemented in stacked shallow water (SSW) mode, in which case we have 1/N^2 = h/g'. More specifically, this commit adds a new subroutine that computes the coupling coefficient associated with GL90 via a_cpl_gl90 = nu / h = kappa_GM * f^2 / g' or a_cpl_gl90 = nu / h = f^2 * alpha / h. Further, a_cpl_gl90 is multiplied by a function (botfn), which is 0 within the GL90 bottom boundary layer, whose depth is set by Hbbl_gl90, and 1 otherwise. This modification is necessary to avoid fluxing momentum into vanished layers that ride over steep topography. Finally, a_cpl_gl90 is added to a_cpl, where the latter is the coupling coefficient associated with the remaining vertical stresses, used in the vertical viscosity solver.

These changes include: - Change the units of the (apparently unused) optional read_khdt_[xy] arguments to tracer_hordiff from [m2] to [L2 ~> m2] - Correct a tiny number used for safety in the denominator of a normalization factor based on the (nondimensional) masks from H_subroundoff to a tiny nondimensional number, giving an expression that is dimensionally consistent. Without this change, the diagnostic "KHTR_h" will vary with large enough negative values of H_RESCALE_POWER. - Replace a local variable in bulkmixedlayer_init with units of time with distinct get_param calls setting the default for BUFFER_LAY_DETRAIN_TIME depending on which buffer layer detrainment scheme is used. - Correct the dimensions of the "land_mask" diagnostic internal_tides_init from "logical" to "nondim", because it is a real multiplicable mask, not a boolean logical mask. - Eliminate the internal variable L2_to_Z2 in the calculate_projected_state routine in MOM_kappa_shear which had been described incorrectly and ultimately was not helpful. - Corrected the allocated size declaration for three 3-d v-face arrays - Add comments highlighting a non-stride-1 loop structure for openMP threading in tracer_epipycnal_ML_diff that required the addition of 3 extra 3-d arrays and might be a performance liability in non-openMP configurations. - Extensive modification of the comments describing the variables in MOM_tracer_hordiff to clearly indicate the units of each real variable and similarly of one variable in MOM_geothermal. All answers are bitwise identical unless very large rescaling is done for thickness units, and the only change in model output is to the documented units of one diagnostic that is not used often, and to the diagnostic "KHTR_h" when large enough negative values of H_RESCALE_POWER are used. --- .../lateral/MOM_internal_tides.F90 | 6 +- .../vertical/MOM_bulk_mixed_layer.F90 | 12 ++- .../vertical/MOM_geothermal.F90 | 10 +- .../vertical/MOM_kappa_shear.F90 | 10 +- src/tracer/MOM_tracer_hor_diff.F90 | 98 +++++++++++-------- 5 files changed, 76 insertions(+), 60 deletions(-) diff --git a/src/parameterizations/lateral/MOM_internal_tides.F90 b/src/parameterizations/lateral/MOM_internal_tides.F90 index 8414e27f8c..dc0daecd8e 100644 --- a/src/parameterizations/lateral/MOM_internal_tides.F90 +++ b/src/parameterizations/lateral/MOM_internal_tides.F90 @@ -2346,8 +2346,8 @@ subroutine internal_tides_init(Time, G, GV, US, param_file, diag, CS) default=.false.) call get_param(param_file, mdl, "CDRAG", CS%cdrag, & "CDRAG is the drag coefficient relating the magnitude of "//& - "the velocity field to the bottom stress.", units="nondim", & - default=0.003) + "the velocity field to the bottom stress.", & + units="nondim", default=0.003) call get_param(param_file, mdl, "INTERNAL_TIDE_ENERGIZED_ANGLE", CS%energized_angle, & "If positive, only one angular band of the internal tides "//& "gets all of the energy.

By default all answers are bitwise identical, but there are new entries in the MOM_parameter_doc.all files for some configurations that use the MOM6 surface wave module. --- src/user/MOM_wave_interface.F90 | 137 ++++++++++++++++++++------------ 1 file changed, 86 insertions(+), 51 deletions(-) diff --git a/src/user/MOM_wave_interface.F90 b/src/user/MOM_wave_interface.F90 index 1a1c06018e..70c0b4c71f 100644 --- a/src/user/MOM_wave_interface.F90 +++ b/src/user/MOM_wave_interface.F90 @@ -140,7 +140,8 @@ module MOM_wave_interface logical :: DataOver_initialized !< Flag for DataOverride Initialization !

Currently, .mod depends on .o, and changes to a module do not trigger rebuilds of dependent source. Rather than try to sort out the rule order, which could even depend on compiler internals, this patch just adds both object and module output files as dependencies, and rebuilds if either changes. We might want to come back to this someday and understand the actual order of rule execution. Thanks to Alistair Adcroft (@adcroft) for proposing this solution. --- ac/makedep | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) diff --git a/ac/makedep b/ac/makedep index 5954f1aae5..439679f17d 100755 --- a/ac/makedep +++ b/ac/makedep @@ -136,6 +136,10 @@ def create_deps(src_dirs, makefile, debug, exec_target, fc_rule, # Write rule for each object from Fortran for o in sorted(o2F90.keys()): found_mods = [m for m in o2uses[o] if m in all_modules] + found_objs = [mod2o[m] for m in o2uses[o] if m in all_modules] + found_deps = [ + dep for pair in zip(found_mods, found_objs) for dep in pair + ] missing_mods = [m for m in o2uses[o] if m not in all_modules] incs = nested_inc(o2h[o] + o2inc[o], f2F) incdeps = sorted(set([f2F[f] for f in incs if f in f2F])) @@ -145,7 +149,8 @@ def create_deps(src_dirs, makefile, debug, exec_target, fc_rule, print("# object:", o, file=file) print("# modules:", ' '.join(o2mods[o]), file=file) print("# uses:", ' '.join(o2uses[o]), file=file) - print("# found:", ' '.join(found_mods), file=file) + print("# found mods:", ' '.join(found_mods), file=file) + print("# found objs:", ' '.join(found_objs), file=file) print("# missing:", ' '.join(missing_mods), file=file) print("# includes_all:", ' '.join(incs), file=file) print("# includes_pth:", ' '.join(incdeps), file=file) @@ -153,7 +158,7 @@ def create_deps(src_dirs, makefile, debug, exec_target, fc_rule, print("# program:", ' '.join(o2prg[o]), file=file) if o2mods[o]: print(' '.join(o2mods[o])+':', o, file=file) - print(o + ':', o2F90[o], ' '.join(incdeps+found_mods), file=file) + print(o + ':', o2F90[o], ' '.join(incdeps+found_deps), file=file) print('\t'+fc_rule, ' '.join(incargs), file=file) # Write rule for each object from C From 5f1572f377ee2ddc6ff58ecd63532c6a7da614ae Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Mon, 19 Dec 2022 09:37:07 -0500 Subject: [PATCH 0544/1329] +Revise interfaces to horiz_interp_and_extract Revised the interface to the two horiz_interp_and_extract to eliminate the unused reentrant_x and tripolar_n arguments and to rename the conversion argument to scale and make it the last mandatory argument in anticipation that we might decide to make it optional, similarly to other routines like MOM_read_data. The renaming is because we use 'conversion' to indicate how the internal representation is to be rescaled for output, most prominently in register_diag_field, whereas everywhere else where we are rescaling input to the model's internal units, we use a scale argument. This makes the convention self-consistent across the MOM6 code, and should avoid some confusion. The calls to these routines were updated in 8 places in 4 modules. In 8 places the get_param calls for TRIPOLAR_N or REENTRANT_X that are no longer needed were eliminated as were the associated internal variables. This commit also includes some additions to comments near the changes that were directly tied to this commit. All answers are bitwise identical, but there are changes to a publicly visible interface; code that tries to use the old interface will not compile. --- src/framework/MOM_horizontal_regridding.F90 | 59 ++++++++++--------- .../MOM_state_initialization.F90 | 43 +++++++------- .../MOM_tracer_initialization_from_Z.F90 | 41 +++++++------ src/ocean_data_assim/MOM_oda_driver.F90 | 21 ++++--- .../vertical/MOM_ALE_sponge.F90 | 37 ++++-------- 5 files changed, 97 insertions(+), 104 deletions(-) diff --git a/src/framework/MOM_horizontal_regridding.F90 b/src/framework/MOM_horizontal_regridding.F90 index bbb5ae0e15..7a0ace9279 100644 --- a/src/framework/MOM_horizontal_regridding.F90 +++ b/src/framework/MOM_horizontal_regridding.F90 @@ -250,14 +250,13 @@ subroutine fill_miss_2d(aout, good, fill, prev, G, acrit, num_pass, relc, debug, end subroutine fill_miss_2d !> Extrapolate and interpolate from a file record -subroutine horiz_interp_and_extrap_tracer_record(filename, varnam, conversion, recnum, G, tr_z, mask_z, & - z_in, z_edges_in, missing_value, reentrant_x, tripolar_n, & +subroutine horiz_interp_and_extrap_tracer_record(filename, varnam, recnum, G, tr_z, mask_z, & + z_in, z_edges_in, missing_value, scale, & homogenize, m_to_Z, answers_2018, ongrid, tr_iter_tol, answer_date) character(len=*), intent(in) :: filename !< Path to file containing tracer to be !! interpolated. character(len=*), intent(in) :: varnam !< Name of tracer in file. - real, intent(in) :: conversion !< Conversion factor for tracer [CU conc-1 ~> 1] integer, intent(in) :: recnum !< Record number of tracer to be read. type(ocean_grid_type), intent(inout) :: G !< Grid object real, allocatable, dimension(:,:,:), intent(out) :: tr_z @@ -271,10 +270,10 @@ subroutine horiz_interp_and_extrap_tracer_record(filename, varnam, conversion, real, allocatable, dimension(:), intent(out) :: z_edges_in !< Cell grid edge values for input data [Z ~> m] real, intent(out) :: missing_value !< The missing value in the returned array, scaled - !! with conversion to avoid accidentally having valid - !! values match missing values [CU ~> conc] - logical, intent(in) :: reentrant_x !< If true, this grid is reentrant in the x-direction - logical, intent(in) :: tripolar_n !< If true, this is a northern tripolar grid + !! to avoid accidentally having valid values match + !! missing values [CU ~> conc] + real, intent(in) :: scale !< Scaling factor for tracer into the internal + !! units of the model [CU conc-1 ~> 1] logical, optional, intent(in) :: homogenize !< If present and true, horizontally homogenize data !! to produce perfectly "flat" initial conditions real, optional, intent(in) :: m_to_Z !< A conversion factor from meters to the units @@ -311,7 +310,7 @@ subroutine horiz_interp_and_extrap_tracer_record(filename, varnam, conversion, real, dimension(:), allocatable :: lon_in !

Also use these ocean_grid_type arguments in calls to register_shelfwave_OBC, register_RGC_tracer and register_advection_test_tracer. Within these three routines, the contents of the ocean_grid_type are used to specify axis units. The new runtime parameter SHELFWAVE_AMPLITUDE was added to allow for run-time control of the amplitude of the shelfwave test case. By default all answers are bitwise identical, but there are some changes in the units of parameters as documented in the MOM_parameter_doc files and a new entry in these files for the shelfwave test case. --- src/core/MOM.F90 | 6 +- src/core/MOM_boundary_update.F90 | 16 +++-- src/tracer/MOM_tracer_flow_control.F90 | 36 +++++------ src/tracer/RGC_tracer.F90 | 15 ++--- src/tracer/advection_test_tracer.F90 | 89 +++++++++++++------------- src/user/shelfwave_initialization.F90 | 79 ++++++++++------------- 6 files changed, 114 insertions(+), 127 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 3cac9583cb..c0ff15e858 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -2177,7 +2177,7 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, restart_CSp, & "at the end of the step.", default=.false.) if (CS%split) then - call get_param(param_file, "MOM", "DTBT", dtbt, default=-0.98) + call get_param(param_file, "MOM", "DTBT", dtbt, units="s or nondim", default=-0.98) default_val = US%T_to_s*CS%dt_therm ; if (dtbt > 0.0) default_val = -1.0 CS%dtbt_reset_period = -1.0 call get_param(param_file, "MOM", "DTBT_RESET_PERIOD", CS%dtbt_reset_period, & @@ -2637,7 +2637,7 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, restart_CSp, & !

This module contains the subroutines that, along with the -!! subroutines that it calls, implements diapycnal mass and momentum -!! fluxes and a bulk mixed layer.

The subroutine make_frazil facilitates the formation of frazil ice when the ocean water +!! drops below the in situ freezing point by heating the water to the freezing point and +!! accumulating the required heat for exchange with the sea-ice module. +!! +!! The subroutine adjust_salt adds salt as necessary to keep the salinity above a +!! specified minimum value, and keeps track of the cumulative additions. If the minimum +!! salinity is the natural value of 0, this routine should never do anything. +!! +!! The subroutine differential_diffuse_T_S solves a pair of tridiagonal equations for +!! the diffusion of temperatures and salinities with differing diffusivities. +!! +!! The subroutine triDiagTS solves a tridiagonal equations for the evolution of temperatures +!! and salinities due to net entrainment by layers and a diffusion with the same diffusivity. +!! +!!

The dual-stream entrainment scheme of MacDougall and Dewar (JPO, -!! 1997) is used for combined diapycnal advection and diffusion, -!! calculated implicitly and potentially with the Richardson number -!! dependent mixing, as described by Hallberg (MWR, 2000). Diapycnal -!! advection is fundamentally the residual of diapycnal diffusion, -!! so the fully implicit upwind differencing scheme that is used is -!! entirely appropriate. The downward buoyancy flux in each layer -!! is determined from an implicit calculation based on the previously -!! calculated flux of the layer above and an estimated flux in the -!! layer below. This flux is subject to the following conditions: -!! (1) the flux in the top and bottom layers are set by the boundary -!! conditions, and (2) no layer may be driven below an Angstrom thick- -!! ness. If there is a bulk mixed layer, the buffer layer is treat- -!! ed as a fixed density layer with vanishingly small diffusivity. +!! The subroutine diagnoseMLDbyEnergy diagnoses a mixed layer depth based on a mixing-energy +!! criterion, as described by Reichl et al., 2022, JGR: Oceans, doi:10.1029/2021JC018140. !! -!! diabatic takes 5 arguments: the two velocities (u and v), the -!! thicknesses (h), a structure containing the forcing fields, and -!! the length of time over which to act (dt). The velocities and -!! thickness are taken as inputs and modified within the subroutine. -!! There is no limit on the time step. +!! The subroutine applyBoundaryFluxesInOut updates the layer thicknesses, temperatures and +!! salinities due to the application of the surface forcing.

The default value for dRho_dS from the EOS code (0.8 kg m-3 ppt-1) does not match hard coded value here (1 kg m-3 ppt-1), but in the existing tests using adjustment_initialization DRHO_DS was being explicitly set to the hard-coded value here, so I have chosen to reuse the same parameter with the same default value as is used elsewhere even though it could change answers in cases that do not set DRHO_DS consistently with the previous hard coded parameter. In addition, the previous default value for T_RANGE read into this module (0 degC) did not match the hard-coded range that was being used (1 degC). In this case I have chosen to change the default value for T_RANGE in this module so that by default this will reproduce the previous answers. As a result, there will be changes in the MOM_parameter doc all files for cases (like adjustment2d) that use the adjustment_initialization routines.

This vertical viscosity scheme redistributes momentum in the vertical, and is the equivalent of the Gent & McWilliams (1990) parameterization, but in a TWA (thickness-weighted averaged) set of equations. The vertical viscosity coefficient nu is computed from kappa_GM via thermal wind balance, and the following relation: nu = kappa_GM * f^2 / N^2. The vertical viscosity del_z ( nu del_z u) is applied to the momentum equation with stress-free boundary conditions at the top and bottom. In the current implementation, kappa_GM is assumed either (a) constant or as (b) having an EBT structure. A third possible formulation of nu is depth-independent: nu = f^2 * alpha The latter formulation would be equivalent to a kappa_GM that varies as N^2 with depth. Currently, the GL90 parameterization is only implemented in stacked shallow water (SSW) mode, in which case we have 1/N^2 = h/g'. More specifically, this commit adds a new subroutine that computes the couping coefficient associated with GL90 via a_cpl_gl90 = nu / h = kappa_GM * f^2 / g' or a_cpl_gl90 = nu / h = f^2 * alpha / h. Further, a_cpl_gl90 is multiplied by a function (botfn), which is 0 within the GL90 bottom boundary layer, whose depth is set by Hbbl_gl90, and 1 otherwise. This modification is necessary to avlid fluxing momentum into vanished layers that ride over steep topography. Finally, a_cpl_gl90 is added to a_cpl, where the latter is the coupling coefficient associated with the remaining vertical stresses, used in the vertical viscosity solver. More information can be found in Loose et al. (https://www.essoar.org/doi/abs/10.1002/essoar.10512867.1), Appendix B. New diagnostics: * au_gl90_visc: zonal viscous coupling coefficient associated with GL90, is contained in au_visc * av_gl90_visc: meridional viscous coupling coefficient associated with GL90, is contained in av_visc * Kv_gl90_u: GL90 vertical viscosity at u-points, is contained in Kv_u * Kv_gl90_v: GL90 vertical viscosity at v-points, is contained in Kv_v * du_dt_visc_gl90: zonal acceleration due to GL90 vertical viscosity, included in du_dt_visc * dv_dt_visc_gl90: meridional acceleration due to GL90 vertical viscosity, included in dv_dt_visc * GLwork: Kinetic Energy Source from GL90 Vertical Viscosity The energetics of the GL90 parameterization (named "GLwork") are intentionally computed in MOM_vert_friction, rather than in MOM_diagnostics, where the reamining kinetic energy budget terms are computed. We have to do the computation in MOM_vert_friction to ensure sign- definiteness when GLwork is summed in the vertical. Indeed, MOM_diagnostics does not have access to the velocities and thicknesses used in the vertical solver, but rather uses a time-mean barotropic transport [uv]h to compute the energy budget diagnostics. A detailed discussion and exploration of this issue can be found in https://github.com/ocean-eddy-cpt/MOM6/issues/25. As a result of not computing the energetics in MOM_diagnostics, GLwork is not exactly contained in KE_visc. KE_visc represents the energetics of all vertical viscosity contributions, including the GL90 vertical viscosity. We could implement a term "KE_visc_gl90" that can be 1-to-1 compared to KE_visc; that is, KE_visc - KE_visc_gl90 would represent exactly the energetics of all viscosity contributions EXCEPT the GL90 viscosity. If we implemented KE_visc_gl90, this term would in practice be very similar as GLwork, but sign-definiteness is not ensured, see above. --- src/core/MOM_variables.F90 | 4 + .../vertical/MOM_vert_friction.F90 | 184 +++++++++++++++++- 2 files changed, 182 insertions(+), 6 deletions(-) diff --git a/src/core/MOM_variables.F90 b/src/core/MOM_variables.F90 index 8279afa954..35cdf3038a 100644 --- a/src/core/MOM_variables.F90 +++ b/src/core/MOM_variables.F90 @@ -168,6 +168,10 @@ module MOM_variables PFv => NULL(), & !< Meridional acceleration due to pressure forces [L T-2 ~> m s-2] du_dt_visc => NULL(), &!< Zonal acceleration due to vertical viscosity [L T-2 ~> m s-2] dv_dt_visc => NULL(), &!< Meridional acceleration due to vertical viscosity [L T-2 ~> m s-2] + du_dt_visc_gl90 => NULL(), &!< Zonal acceleration due to GL90 vertical viscosity + !

This change requires that an ocean grid type be passed to register_DOME_tracer and USER_register_tracer_example instead of a hor_index type. Descriptions of the units of a number of internal variables were added to both modules. In addition, the confusing (and dimensionally heterogeneous) trdc array in tracer_column_physics was replaced with 3 internal variables with more suggestive names.

It was already being provided except in a call for unit testing, so adding it as a parameter there led to a simple change and the elimination of a hard-coded dimensional parameter. Also replaced the hard-coded fill values over land in MOM_temp_salt_initialize_from_Z for temperatures and salinities before regridding with the runtime variables temp_land_fill and salt_land_fill that are already being used in the same routine. This does not change any answers, probably because these values are not actually used.

A common API for interacting with files is defined in the `MOM_file` class, and two implementations are provided: * `MOM_infra_file`, using the "infra" framework (i.e. FMS) * `MOM_netcdf_file`, using native netCDF framework This separation allows us to define certain generic functions by class, and platform-specific functions by type. It will also allow for removal of legacy FMS1 operations which are no longer used for the majority of I/O but are still required for isolated MOM files. This change will allow us to move incompatible files from the FMS to the netCDF implementation, while still preserving a common structure for both files. The majority of the details of `MOM_file` and its subclasses are defined in `MOM_io_file.F90`, which is exclusively accessed through `MOM_io.F90`. The netCDF implementation, designed to be used by `MOM_netcdf_file` but is designed as a standalone system, is defined in `MOM_netcdf.F90`. *Interface* `MOM_file` includes the following functions: * `open` * `close` * `flush` * `register_axis` * `register_field` * `write_attribute` * `write_field` * `file_is_open` * `get_file_info` * `get_file_fields` * `get_field_atts` * `read_field_chksum` Most are designed to resemble the existing MOM I/O operations. Note that some of these have not yet been implemented for `MOM_netcdf_file`, since they are never used in the model. `MOM_file_infra` includes the following additional operations: * `get_file_times` * `get_file_fieldtypes` See documentation for usage of these functions. The "axis"/"field" model from FMS1 has been preserved, where axes are associated with variables which contain the grid point, and fields are defined with respect to the file's axes. Operations such as field counters will exclude any variables associated with the axes. The `axistype` and `fieldtype` from FMS have been replaced with new abstractions (`MOM_axis` and `MOM_field`). Internally, these point to either the FMS types or equivalent netCDF types. *Implementation* Each file type contains an instance of its native type, as well as lists of associated axes and fields. List are implemented as linked lists of names (stored as `label`) which are used to identify and extract or write the axis/field to the internal type. The mechanics of this are largely hidden from the user and can be changed in the future, if needed, without disruption to the rest of the codebase. The current netCDF implementation very closely mirrors the FMS infra behavior, but this can be relaxed or modified as needed. netCDF I/O is currently only designed for serial I/O, with all of the data on the root PE. Further development would be needed to support any kind of parallel I/O. *Current Usage* Two functions have been transferred from infra to the netCDF I/O: * `Depth_list.nc` * `ocean.stats.nc` The following legacy functions and types from FMS have been preserved: * `create_file` * `reopen_file` * `file_type` * `open_file` * `get_file_info` * `get_file_fields` * `get_file_times` This is primarily to preserve compatibility with SIS2, but may also be useful for other code, such as model drivers. These may be phased out in the future, however. --- config_src/infra/FMS2/MOM_io_infra.F90 | 4 +- src/ALE/MOM_hybgen_regrid.F90 | 13 +- src/ALE/MOM_regridding.F90 | 14 +- src/diagnostics/MOM_sum_output.F90 | 72 +- src/framework/MOM_io.F90 | 442 ++++- src/framework/MOM_io_file.F90 | 1654 +++++++++++++++++ src/framework/MOM_netcdf.F90 | 755 ++++++++ src/framework/MOM_restart.F90 | 48 +- src/ice_shelf/MOM_ice_shelf.F90 | 2 +- .../MOM_coord_initialization.F90 | 12 +- .../MOM_shared_initialization.F90 | 12 +- 11 files changed, 2854 insertions(+), 174 deletions(-) create mode 100644 src/framework/MOM_io_file.F90 create mode 100644 src/framework/MOM_netcdf.F90 diff --git a/config_src/infra/FMS2/MOM_io_infra.F90 b/config_src/infra/FMS2/MOM_io_infra.F90 index c49c124ae0..54b9dfb78b 100644 --- a/config_src/infra/FMS2/MOM_io_infra.F90 +++ b/config_src/infra/FMS2/MOM_io_infra.F90 @@ -509,8 +509,8 @@ subroutine open_ASCII_file(unit, file, action, threading, fileset) !

Changes: - Added the target "executables to tc4/Makefile, so only compilation occurs when invoked. The "all" target still compiles if needed. - Added target "preproc-compile" to .testing/Makefile whcih invokes the "executables" target of tc4/Makefile. The target "preproc" still compiles if needed. - Added `make-preproc-compile` to the gitlab pipeline prior to submitting the "make test" job to the compute nodes. - I also disconnected the "clean.stats" target from "clean.preproc" since the latter removes the pre-processing executables too and given that we can't re-compile those and re-create the stats from the same location it makes sense to keep those clean steps separated. --- .gitlab-ci.yml | 2 ++ .testing/Makefile | 4 +++- .testing/tc4/Makefile.in | 1 + 3 files changed, 6 insertions(+), 1 deletion(-) diff --git a/.gitlab-ci.yml b/.gitlab-ci.yml index fbc2854b33..6291d2bd84 100644 --- a/.gitlab-ci.yml +++ b/.gitlab-ci.yml @@ -182,6 +182,7 @@ actions:gnu: - cd .testing - module unload PrgEnv-pgi PrgEnv-intel PrgEnv-gnu darshan ; module load PrgEnv-gnu ; module unload netcdf gcc ; module load gcc/7.3.0 cray-hdf5 cray-netcdf - make -s -j + - make preproc-compile -s -j - echo -e "\e[0Ksection_end:`date +%s`:compile\r\e[0K" - (echo '#!/bin/bash';echo 'make MPIRUN="srun -mblock --exclusive" test -s -j') > job.sh - sbatch --clusters=c3,c4 --nodes=5 --time=0:05:00 --account=gfdl_o --qos=debug --job-name=MOM6.gnu.testing --output=log.$CI_JOB_ID --wait job.sh || ( cat log.$CI_JOB_ID ; exit 911 ) @@ -201,6 +202,7 @@ actions:intel: - cd .testing - module unload PrgEnv-pgi PrgEnv-intel PrgEnv-gnu darshan; module load PrgEnv-intel; module unload netcdf intel; module load intel/18.0.6.288 cray-hdf5 cray-netcdf - make -s -j + - make preproc-compile -s -j - echo -e "\e[0Ksection_end:`date +%s`:compile\r\e[0K" - (echo '#!/bin/bash';echo 'make MPIRUN="srun -mblock --exclusive" test -s -j') > job.sh - sbatch --clusters=c3,c4 --nodes=5 --time=0:05:00 --account=gfdl_o --qos=debug --job-name=MOM6.intel.testing --output=log.$CI_JOB_ID --wait job.sh || ( cat log.$CI_JOB_ID ; exit 911 ) diff --git a/.testing/Makefile b/.testing/Makefile index 73a97229d4..0b9c57f675 100644 --- a/.testing/Makefile +++ b/.testing/Makefile @@ -523,6 +523,8 @@ $(foreach c,$(CONFIGS),$(eval $(call CONFIG_DIM_RULE,$(c)))) .PHONY: preproc preproc: tc4/Makefile cd tc4 && $(MAKE) LAUNCHER="$(MPIRUN)" +preproc-compile: tc4/Makefile + cd tc4 && $(MAKE) executables tc4/Makefile: tc4/configure tc4/Makefile.in cd $(@D) && ./configure || (cat config.log && false) @@ -795,7 +797,7 @@ clean.build: .PHONY: clean.stats -clean.stats: clean.preproc +clean.stats: @[ $$(basename $$(pwd)) = .testing ] rm -rf work results diff --git a/.testing/tc4/Makefile.in b/.testing/tc4/Makefile.in index 5a0e441482..714a8f19f1 100644 --- a/.testing/tc4/Makefile.in +++ b/.testing/tc4/Makefile.in @@ -16,6 +16,7 @@ OUT = ocean_hgrid.nc topog.nc temp_salt_ic.nc sponge.nc # Program output all: ocean_hgrid.nc temp_salt_ic.nc +executables: gen_data gen_grid ocean_hgrid.nc: gen_grid $(LAUNCHER) ./gen_grid From 86c39546fbbd3df4947b8faba26ca08d95653bd3 Mon Sep 17 00:00:00 2001 From: Alistair Adcroft Date: Fri, 13 Jan 2023 11:10:36 -0500 Subject: [PATCH 0593/1329] .testing: Add WORKSPACE cpp macro to control scratch space - Added CPP macro "WORKSPACE" which defaults to ".".

The previous version had used non-reproducing sums. This new code is used when HOR_REGRID_ANSWER_DATE >= 20230101, and the comments describing HOR_REGRID_ANSWER_DATE have been updated to reflect this. As a part of this change, the new publicly visible routine homogenize_field was added to the MOM_horizontal_regridding module, so that the homogenization occurs in a single part of the code rather than being spread across several files. By default this commit could lead to answer changes in some cases, depending whether and how HOR_REGRID_ANSWER_DATE is set, but it turns out that the existing single_column test cases that use this have only 4 points and happen to give the same answers with either the older or newer version of the code. This commit addresses MOM6 issue #296 (github.com/NOAA-GFDL/MOM6/issues/296), which can be closed as soon as this commit is merged in to the dev/gfdl branch of MOM6. --- src/framework/MOM_horizontal_regridding.F90 | 112 +++++++++++++----- .../MOM_state_initialization.F90 | 28 +---- .../MOM_tracer_initialization_from_Z.F90 | 1 + .../vertical/MOM_ALE_sponge.F90 | 2 + 4 files changed, 91 insertions(+), 52 deletions(-) diff --git a/src/framework/MOM_horizontal_regridding.F90 b/src/framework/MOM_horizontal_regridding.F90 index 7a0ace9279..c2fe772571 100644 --- a/src/framework/MOM_horizontal_regridding.F90 +++ b/src/framework/MOM_horizontal_regridding.F90 @@ -5,6 +5,7 @@ module MOM_horizontal_regridding use MOM_debugging, only : hchksum use MOM_coms, only : max_across_PEs, min_across_PEs, sum_across_PEs, broadcast +use MOM_coms, only : reproducing_sum use MOM_cpu_clock, only : cpu_clock_id, cpu_clock_begin, cpu_clock_end, CLOCK_LOOP use MOM_domains, only : pass_var use MOM_error_handler, only : MOM_mesg, MOM_error, FATAL, WARNING, is_root_pe @@ -24,7 +25,7 @@ module MOM_horizontal_regridding #include -public :: horiz_interp_and_extrap_tracer, myStats +public :: horiz_interp_and_extrap_tracer, myStats, homogenize_field !> Extrapolate and interpolate data interface horiz_interp_and_extrap_tracer @@ -321,7 +322,6 @@ subroutine horiz_interp_and_extrap_tracer_record(filename, varnam, recnum, G, tr logical :: found_attr logical :: add_np logical :: is_ongrid - character(len=8) :: laynum type(horiz_interp_type) :: Interp type(axis_info), dimension(4) :: axes_info !

This commit corrects this inconsistency, while also rescaling the internal slope variables in that routine to also have the proper units of [Z L-1 ~> nondim]. In so doing, several rescaling factors could be eliminated from the calculations. In addition, the slopes used in calc_QG_Leith_viscosity were also being rescaled with the wrong factor or had dimensionally incorrect tiny values in some denominators, and this has been corrected as well. In testing this rescaling fix, a number of other bugs were identified with USE_QG_LEITH_VISC=True (as described at github.com/mom-ocean/MOM6/issues/1590), so a fatal error message was added if this option is enabled. All answers in the MOM6-examples test suite are bitwise identical, but the code will now give a fatal error if USE_QG_LEITH_VISC=.true. --- .../lateral/MOM_hor_visc.F90 | 8 +- .../lateral/MOM_lateral_mixing_coeffs.F90 | 90 +++++++++++-------- 2 files changed, 59 insertions(+), 39 deletions(-) diff --git a/src/parameterizations/lateral/MOM_hor_visc.F90 b/src/parameterizations/lateral/MOM_hor_visc.F90 index 0574297c0c..e6dd131a99 100644 --- a/src/parameterizations/lateral/MOM_hor_visc.F90 +++ b/src/parameterizations/lateral/MOM_hor_visc.F90 @@ -1936,8 +1936,14 @@ subroutine hor_visc_init(Time, G, GV, US, param_file, diag, CS, ADp) call get_param(param_file, mdl, "USE_QG_LEITH_VISC", CS%use_QG_Leith_visc, & "If true, use QG Leith nonlinear eddy viscosity.", & default=.false., do_not_log=.not.(CS%Leith_Kh .or.

The two are only the same in the limit of a uniform bottom depth, and isopycnal coordinate and a vertically uniform diffusivity, and the new phrases reflect what is actually being done. In addition, the "Brunt-Vaisala frequency" is now being described as the "buoyancy frequency" for greater clarity of language and less use of jargon. Some units were also added to the descriptions using the standard syntax used elsewhere in the code. For now, these changes are restricted to the internal comments, so that there are no changes in the MOM_parameter_doc or output files. All answers are bitwise identical. --- .../lateral/MOM_thickness_diffuse.F90 | 134 +++++++++--------- 1 file changed, 69 insertions(+), 65 deletions(-) diff --git a/src/parameterizations/lateral/MOM_thickness_diffuse.F90 b/src/parameterizations/lateral/MOM_thickness_diffuse.F90 index b4092d3d43..4e12aeeaad 100644 --- a/src/parameterizations/lateral/MOM_thickness_diffuse.F90 +++ b/src/parameterizations/lateral/MOM_thickness_diffuse.F90 @@ -1,4 +1,4 @@ -!> Thickness diffusion (or Gent McWilliams) +!> Isopycnal height diffusion (or Gent McWilliams diffusion) module MOM_thickness_diffuse !

Specifically, it adds a missing scale factor for the time_interp_external call for the offline data Eddy kinetic energy used in MEKE when EKE_SOURCE=file. It also corrects the documented units and conversion factors for 4 diagnostics related to machine learning within MEKE. This commit also adds or amends comments to document the units of 27 internal variables in MOM_MEKE.F90, and corrected a few spelling errors in comments. All answers and output are bitwise identical in the existing MOM6-examples test suite, but there may be other examples where the units or rescaling of diagnostics are corrected or (in cases using EKE_SOURCE=file) where dimensional consistency testing issues are corrected for the solutions themselves. --- src/parameterizations/lateral/MOM_MEKE.F90 | 104 +++++++++++---------- 1 file changed, 55 insertions(+), 49 deletions(-) diff --git a/src/parameterizations/lateral/MOM_MEKE.F90 b/src/parameterizations/lateral/MOM_MEKE.F90 index 013cfd386a..8d6eda728d 100644 --- a/src/parameterizations/lateral/MOM_MEKE.F90 +++ b/src/parameterizations/lateral/MOM_MEKE.F90 @@ -45,7 +45,7 @@ module MOM_MEKE integer, parameter :: RV_IDX = 3 !< Index of surface relative vorticity in the feature array integer, parameter :: RD_DX_Z_IDX = 4 !< Index of the radius of deformation over the grid size in the feature array -integer, parameter :: EKE_PROG = 1 !< Use prognostic equation to calcualte EKE +integer, parameter :: EKE_PROG = 1 !< Use prognostic equation to calculate EKE integer, parameter :: EKE_FILE = 2 !< Read in EKE from a file integer, parameter :: EKE_DBCLIENT = 3 !< Infer EKE using a neural network @@ -141,7 +141,7 @@ module MOM_MEKE logical :: online_analysis !< If true, post the EKE used in MOM6 at every timestep character(len=5) :: model_key = 'mleke' !< Key where the ML-model is stored character(len=7) :: key_suffix !< Suffix appended to every key sent to Redis - real :: eke_max !< The maximum value of EKE considered physically reasonable + real :: eke_max !< The maximum value of EKE considered physically reasonable [L2 T-2 ~> m2 s-2] !

Also revised comments to make it clear that the MOM6 code for the UNESCO equation of state is based on the Jackett and MacDougall (1995) refit to the UNESCO equation of state (which uses potential temperature as a state variable) as opposed to the original UNESCO equation of state, as documented in an appendix to Gill (1982) (which uses in-situ temperature as a state variable). Also corrected a handful of spelling errors in comments.

This is includes adding a new optional omit_corners argument to the MOM_state_chksum and MOM_thermo_chksum routines, and revising the haloshift, omit_corners or symmetric arguments on 6 subroutine calls, to check more appropriate loop ranges. All answers are bitwise identical, but there is a new optional argument to three publicly visible debugging routines. --- src/core/MOM.F90 | 6 +-- src/core/MOM_checksum_packages.F90 | 50 ++++++++++++++-------- src/core/MOM_dynamics_split_RK2.F90 | 6 +-- src/parameterizations/lateral/MOM_MEKE.F90 | 4 +- 4 files changed, 39 insertions(+), 27 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index daa40ba052..00e748bdc1 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -1529,9 +1529,9 @@ subroutine step_MOM_thermo(CS, G, GV, US, u, v, h, tv, fluxes, dtdia, & call preAle_tracer_diagnostics(CS%tracer_Reg, G, GV) if (CS%debug) then - call MOM_state_chksum("Pre-ALE ", u, v, h, CS%uh, CS%vh, G, GV, US) - call hchksum(tv%T,"Pre-ALE T", G%HI, haloshift=1, scale=US%C_to_degC) - call hchksum(tv%S,"Pre-ALE S", G%HI, haloshift=1, scale=US%S_to_ppt) + call MOM_state_chksum("Pre-ALE ", u, v, h, CS%uh, CS%vh, G, GV, US, omit_corners=.true.) + call hchksum(tv%T,"Pre-ALE T", G%HI, haloshift=1, omit_corners=.true., scale=US%C_to_degC) + call hchksum(tv%S,"Pre-ALE S", G%HI, haloshift=1, omit_corners=.true., scale=US%S_to_ppt) call check_redundant("Pre-ALE ", u, v, G, unscale=US%L_T_to_m_s) endif call cpu_clock_begin(id_clock_ALE) diff --git a/src/core/MOM_checksum_packages.F90 b/src/core/MOM_checksum_packages.F90 index 80630084b9..bc908ee60c 100644 --- a/src/core/MOM_checksum_packages.F90 +++ b/src/core/MOM_checksum_packages.F90 @@ -39,7 +39,7 @@ module MOM_checksum_packages ! ============================================================================= !> Write out chksums for the model's basic state variables, including transports. -subroutine MOM_state_chksum_5arg(mesg, u, v, h, uh, vh, G, GV, US, haloshift, symmetric, vel_scale) +subroutine MOM_state_chksum_5arg(mesg, u, v, h, uh, vh, G, GV, US, haloshift, symmetric, omit_corners, vel_scale) character(len=*), & intent(in) :: mesg !< A message that appears on the chksum lines. type(ocean_grid_type), intent(in) :: G !< The ocean's grid structure. @@ -60,6 +60,7 @@ subroutine MOM_state_chksum_5arg(mesg, u, v, h, uh, vh, G, GV, US, haloshift, sy integer, optional, intent(in) :: haloshift !< The width of halos to check (default 0). logical, optional, intent(in) :: symmetric !< If true, do checksums on the fully symmetric !! computational domain. + logical, optional, intent(in) :: omit_corners !< If true, avoid checking diagonal shifts real, optional, intent(in) :: vel_scale !< The scaling factor to convert velocities to [m s-1] real :: scale_vel !

This would cause such cases to fail to reproduce across restarts or use uninitialize or incorrect arrays, but because the Pacanowski and Philader parameterization is very out-dated it appears not to be used in any active test case. Moreover, no one has reported any such issues yet. Therefore, rather than adding a flag to reproduce the old (unreproducing) results, this commit simply corrects this bug. The (case-sensitive) parameter "Use_PP81" was also formally obsoleted.

It is designed to resemble the existing `MOM_read_data` function. Motivation ---------- Legacy input files may contain content which is not supported by the newest framework I/O (FMS). In order to retain support for these input files, particularly over a wider range of compilers, this patch provides an alternative method for reading these files. Interface --------- As with `MOM_read_data`, the function is provided with a netCDF filepath and a variable name, and returns the values to a provided variable. The `global_file` and `file_may_be_4d` flags have been dropped, since they are related to specific FMS2 compatibility issues. (Global vs domain-decomposed reads is controlled by the presence of a `MOM_domain`) Limited domain-decomposed I/O is supported, providing parallel I/O over a single file, to the extent supported by the filesystem. Parallelization over multiple files, as in FMS I/O, is not supported. Each FMS PE (MPI rank) reads its own segment, as defined by its MOM_domain. Output can be saved to either compute or data domains; as in FMS, the appropriate placement is inferred from the size of the output array. Support is currently limited to time-independent 2D arrays with center-cell indexing. That is, the `position` and `timelevel` arguments are not yet supported. The subroutines raise an error if these are provided, as an indication that they may support them in the future. Implementation -------------- Internally, the function opens a `MOM_netcdf_file`, generates its field/axis manifest, and reads the field contents. As with `MOM_read_data`, an internal rotation may be applied. The file is closed upon completion. (This behavior is designed to emulate the existing `MOM_read_data`; in a future implementation, we may want to use a persistent file handle which reduces the number of I/O operations.) Opening a `MOM_netcdf_file` now supports a `MOM_domain` argument, which is used to determine the index bounds of its local segment of the global domain. This is used to compute appropriate bounds for the native netCDF IO calls. As part of these changes, the `get_file_fields` function has been separated into itself and a new function, `update_file_contents`, which populates the internal axis and field metadata list. Usage ----- The following fields have been moved to the native netCDF IO: * `tideamp` (tidal mixing, FMS surface forcing) * `gustiness` (solo and FMS surface forcing) * `h2` (roughness in tidal mixing) This only comprises the fields which must be handled natively in order for the GFDL regression suite to pass with the PGI compiler; more files could be moved to native I/O in the future. Bugfixes -------- Some bugfixes to the netCDF I/O are also included: * `filename` attribute is now only written in an writeable state * Previously, `get_file_fields` (and now `update_file_contents`) assumed that every axis had an equivalent variable, which could lead to potential errors if an axis had no equvalent field, such as index bounds. We now count the number of variables with matching dimension names, tagged as axes, rather than assuming that every axis has a variable, and exclude them from the field list. * Not a bugfix, but `hor_index_init` was modified so that `param_file` is now an optional input. This function is used in `MOM_netcdf_file`, where `param_file` is not available. The argument is only used to call `log_param`. Previous usage of these functions was restricted to writing output with well-defined content, so were unaffected by these issues. --- .../FMS_cap/MOM_surface_forcing_gfdl.F90 | 12 +- .../solo_driver/MOM_surface_forcing.F90 | 7 +- src/framework/MOM_hor_index.F90 | 7 +- src/framework/MOM_io.F90 | 63 +++++++ src/framework/MOM_io_file.F90 | 155 ++++++++++++++++-- src/framework/MOM_netcdf.F90 | 60 +++++-- .../vertical/MOM_tidal_mixing.F90 | 11 +- 7 files changed, 279 insertions(+), 36 deletions(-) diff --git a/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 b/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 index 9a00f487e4..f732cb9a56 100644 --- a/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 +++ b/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 @@ -28,6 +28,7 @@ module MOM_surface_forcing_gfdl use MOM_interpolate, only : init_external_field, time_interp_external use MOM_interpolate, only : time_interp_external_init use MOM_io, only : slasher, write_version_number, MOM_read_data +use MOM_io, only : read_netCDF_data use MOM_io, only : stdout_if_root use MOM_restart, only : register_restart_field, restart_init, MOM_restart_CS use MOM_restart, only : restart_init_end, save_restart, restore_state @@ -1507,7 +1508,10 @@ subroutine surface_forcing_init(Time, G, US, param_file, diag, CS, wind_stagger) if (CS%read_TIDEAMP) then TideAmp_file = trim(CS%inputdir) // trim(TideAmp_file) - call MOM_read_data(TideAmp_file,'tideamp',CS%TKE_tidal,G%domain,timelevel=1, scale=US%m_to_Z*US%T_to_s) + !

On some systems, we cannot assume that `python` is the name of the interpreter, and strictly should not even assume that it exists. This is notably an issue on the recent MacOS M1 systems, which use `python3` as its interpreter, and do not provide one named `python`. This patch adds macros to the MOM6 and FMS autoconf builds to detect if Python is on the system, and makes a few attempts to determine the name of the interpreter (python, python3, python2). Perhaps more can be done here, but this is probably sufficient in nearly all cases. --- ac/Makefile.in | 3 ++- ac/configure.ac | 7 +++++++ ac/deps/Makefile.fms.in | 3 ++- ac/deps/configure.fms.ac | 9 ++++++++- 4 files changed, 19 insertions(+), 3 deletions(-) diff --git a/ac/Makefile.in b/ac/Makefile.in index 930816bc8c..43262027e6 100644 --- a/ac/Makefile.in +++ b/ac/Makefile.in @@ -6,6 +6,7 @@ FC = @FC@ LD = @FC@ +PYTHON = @PYTHON@ MAKEDEP = @MAKEDEP@ DEFS = @DEFS@ @@ -32,7 +33,7 @@ rwildcard=$(foreach d,$(wildcard $(1:=/*)),$(call rwildcard,$d,$2) $(filter $(su .PHONY: depend depend: Makefile.dep Makefile.dep: $(MAKEDEP) $(call rwildcard,$(SRC_DIRS),*.h *.c *.inc *.F90) - $(MAKEDEP) -o Makefile.dep -e $(SRC_DIRS) + $(PYTHON) $(MAKEDEP) -o Makefile.dep -e $(SRC_DIRS) # Delete any files associated with configuration (including the Makefile). diff --git a/ac/configure.ac b/ac/configure.ac index 049325a891..dead0579a6 100644 --- a/ac/configure.ac +++ b/ac/configure.ac @@ -221,6 +221,13 @@ AC_COMPILE_IFELSE( ) +# Verify that Python is available +AC_PATH_PROGS([PYTHON], [python python3 python2], [ + AC_MSG_ERROR([Could not find python.]) +]) +AC_ARG_VAR([PYTHON], [Python interpreter command]) + + # Verify that makedep is available AC_PATH_PROG([MAKEDEP], [makedep], [${srcdir}/ac/makedep]) AC_SUBST([MAKEDEP]) diff --git a/ac/deps/Makefile.fms.in b/ac/deps/Makefile.fms.in index e2581cf817..caf4abb9c7 100644 --- a/ac/deps/Makefile.fms.in +++ b/ac/deps/Makefile.fms.in @@ -8,6 +8,7 @@ CC = @CC@ FC = @FC@ LD = @FC@ AR = @AR@ +PYTHON = @PYTHON@ MAKEDEP = @MAKEDEP@ DEFS = @DEFS@ @@ -22,4 +23,4 @@ ARFLAGS = @ARFLAGS@ .PHONY: depend depend: Makefile.dep Makefile.dep: - $(MAKEDEP) -o Makefile.dep -e -x libFMS.a @srcdir@ + $(PYTHON) $(MAKEDEP) -o Makefile.dep -e -x libFMS.a @srcdir@ diff --git a/ac/deps/configure.fms.ac b/ac/deps/configure.fms.ac index 4e0c0f1390..a52533970b 100644 --- a/ac/deps/configure.fms.ac +++ b/ac/deps/configure.fms.ac @@ -158,7 +158,14 @@ AX_FC_ALLOW_ARG_MISMATCH FCFLAGS="$FCFLAGS $ALLOW_ARG_MISMATCH_FCFLAGS" -# Verify makedep +# Verify that Python is available +AC_PATH_PROGS([PYTHON], [python python3 python2], [ + AC_MSG_ERROR([Could not find python.]) +]) +AC_ARG_VAR([PYTHON], [Python interpreter command]) + + +# Verify that makedep is available AC_PATH_PROGS([MAKEDEP], [makedep], [], ["${PATH}:${srcdir}/../../.."]) AS_IF([test -n "${MAKEDEP}"], [ AC_SUBST([MAKEDEP]) From 5f628582069cb6feee3b068dacbd5d2d0405a000 Mon Sep 17 00:00:00 2001 From: Marshall Ward Date: Thu, 23 Feb 2023 10:16:16 -0500 Subject: [PATCH 0640/1329] reopen_MOM_file explicitly runs on root PE reopen_MOM_file includes an inquire test to determine whether we are attempting to reopen an existing file. If missing, it will attempt to create the missing file. The switch from FMS to netCDF I/O exposed a race condition here, where one rank may create the file, and another delayed rank may incorrectly identify this new file as already existing. This resulted in a segmentation fault. Unsure why this was not detected before; it could be that FMS was more resilient to the possibility of missing files. Regardless, the `exists` value was volatile and could lead to potential error. This patch introduces a temporary fix to the issue by checking the root PE and threading value. When threading is single-file, only the root PE participates in the existence test and file creation. This accounts for the case where either the root PE or any larger subset containing the root PE calls the function. It does not account for the more exotic case where a non-root PE many wish to create a file. If threading is set to MULTIPLE (i.e. IO domains) then an error is raised, since there's currently no safe way to implement an equivalent `inquire()` test. We can revisit this function when stronger controls around threaded IO are introduced. But for now, I believe that this is the best that we can do. --- src/framework/MOM_io.F90 | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/src/framework/MOM_io.F90 b/src/framework/MOM_io.F90 index 3cc791dcda..3e90ecd9b1 100644 --- a/src/framework/MOM_io.F90 +++ b/src/framework/MOM_io.F90 @@ -668,6 +668,20 @@ subroutine reopen_MOM_file(IO_handle, filename, vars, novars, fields, & thread = SINGLE_FILE if (PRESENT(threading)) thread = threading + !

Also fixed 42 other inconsistent units in comments in 28 files scattered throughout the MOM6 code. WAVE_HEIGHT_SCALE_FACTOR was added in December 2022 as a part of PR #289 to dev/gfdl. These inconsistent units were detected because they do not match the patterns of other valid units; most are recent additions. Apart from a single unit in a get_param call, only comments are changed, and all answers are bitwise identical. --- .../FMS_cap/MOM_surface_forcing_gfdl.F90 | 4 +-- .../mct_cap/mom_surface_forcing_mct.F90 | 4 +-- .../nuopc_cap/mom_surface_forcing_nuopc.F90 | 4 +-- .../solo_driver/MESO_surface_forcing.F90 | 2 +- .../solo_driver/MOM_surface_forcing.F90 | 26 +++++++++---------- .../solo_driver/user_surface_forcing.F90 | 6 ++--- .../drivers/unit_drivers/MOM_sum_driver.F90 | 2 +- src/ALE/MOM_hybgen_remap.F90 | 4 +-- src/core/MOM.F90 | 2 +- src/core/MOM_continuity_PPM.F90 | 2 +- src/core/MOM_forcing_type.F90 | 8 +++--- src/core/MOM_porous_barriers.F90 | 2 +- src/core/MOM_variables.F90 | 2 +- src/equation_of_state/MOM_EOS.F90 | 4 +-- src/equation_of_state/MOM_EOS_linear.F90 | 2 +- src/framework/MOM_unit_scaling.F90 | 2 +- src/ice_shelf/MOM_ice_shelf_dynamics.F90 | 26 +++++++++---------- .../MOM_state_initialization.F90 | 2 +- .../lateral/MOM_mixed_layer_restrat.F90 | 2 +- .../lateral/MOM_thickness_diffuse.F90 | 2 +- .../vertical/MOM_bulk_mixed_layer.F90 | 4 +-- .../vertical/MOM_kappa_shear.F90 | 2 +- .../vertical/MOM_opacity.F90 | 2 +- .../vertical/MOM_set_diffusivity.F90 | 2 +- .../vertical/MOM_set_viscosity.F90 | 2 +- src/tracer/MOM_offline_aux.F90 | 4 +-- src/tracer/MOM_tracer_Z_init.F90 | 2 +- src/tracer/dye_example.F90 | 2 +- src/tracer/oil_tracer.F90 | 2 +- src/user/MOM_controlled_forcing.F90 | 4 +-- src/user/MOM_wave_interface.F90 | 4 +-- src/user/Rossby_front_2d_initialization.F90 | 2 +- src/user/tidal_bay_initialization.F90 | 2 +- 33 files changed, 70 insertions(+), 72 deletions(-) diff --git a/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 b/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 index f732cb9a56..88d2cb3f42 100644 --- a/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 +++ b/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 @@ -83,14 +83,14 @@ module MOM_surface_forcing_gfdl !! type without any further adjustments to drive the ocean dynamics. !!

This bug only applies to cases where the bulk mixed layer is enabled by setting BULKMIXEDLAYER=True and USE_REGRIDDING=False (i.e., in layered mode configurations with active thermodynamics), however because the default value of ML_MIX_FIRST = 0, this bug does not appear to be used in any active test cases, and it went undetected when it was introduced.

Also initialized the internal `unlim_index` array in `get_netcdf_fields` to fix a problem with using an uninitialized array that was being flagged when run in debug mode. With this commit, the model is once again reproducing the expected answers when rescaling is applied for vertical distances or time.

Wallcraft" Date: Sun, 19 Mar 2023 16:37:44 +0000 Subject: [PATCH 0655/1329] Add PPM_CM and HYCOM1_ONLY_IMPROVES Add "PPM_CW" as an option for INTERPOLATION_SCHEME and REMAPPING_SCHEME. This implements the original Colella and Woodward (1984) edge calculation for PPM. It computes 4th order explicit edge values but constrains them to produce a monotonic profile, which is particularly effective for remapping. INTERPOLATION_SCHEME="PPM_CW" is identical to "REMAPPING_PPM_HYBGEN", but hybgen_PPM_coefs has been replaced by edge_values_explicit_h4cw and PPM_monotonicity for flexibility and to simplify upgrades. Answers with existing INTERPOLATION_SCHEME options are unchanged. REMAPPING_SCHEME="PPM_CW" is a new option which can perform better than "P1M_H2" when used with INTERPOLATION_SCHEME="PPM_CW". Answers with existing REMAPPING_SCHEME options are unchanged. HYCOM1 regridding walks a monotonic density profile to locate the new interface locations where the interface density equals the target density. However, it assumes that moving one interface has no effect on the density at all other interfaces and this need not be the case. When regridding, with HYCOM1_ONLY_IMPROVES=True, an interface is only moved if this improves the fit to its target density. The default of False does not change answers. --- src/ALE/MOM_ALE.F90 | 4 +- src/ALE/MOM_regridding.F90 | 17 +++-- src/ALE/MOM_remapping.F90 | 17 ++++- src/ALE/PPM_functions.F90 | 31 ++++++++- src/ALE/coord_hycom.F90 | 122 +++++++++++++++++++++++++++++---- src/ALE/regrid_edge_values.F90 | 102 ++++++++++++++++++++++++++- src/ALE/regrid_interp.F90 | 27 +++++++- 7 files changed, 297 insertions(+), 23 deletions(-) diff --git a/src/ALE/MOM_ALE.F90 b/src/ALE/MOM_ALE.F90 index 2a9ebc09c8..137f6cee9b 100644 --- a/src/ALE/MOM_ALE.F90 +++ b/src/ALE/MOM_ALE.F90 @@ -206,12 +206,12 @@ subroutine ALE_init( param_file, GV, US, max_depth, CS) call get_param(param_file, mdl, "REMAPPING_SCHEME", string, & "This sets the reconstruction scheme used "//& "for vertical remapping for all variables.

Also updated the weights on the add_scaling calls, which are essentially counts of the frequency of the various unit descriptors in the MOM6 code, to reflect only the counts of variables with doxygen comments (i.e., arguments, function return values and elements of types) but excluding the user, framework and diagnostics directories and the passive tracer packages. All model solutions are bitwise identical, but there will be updated suggestions for combinations of scaling factors that minimize the aliasing of the units that are used. --- src/core/MOM_check_scaling.F90 | 248 +++++++++++++++++---------------- 1 file changed, 131 insertions(+), 117 deletions(-) diff --git a/src/core/MOM_check_scaling.F90 b/src/core/MOM_check_scaling.F90 index 55bd471fee..1d7c27b6fd 100644 --- a/src/core/MOM_check_scaling.F90 +++ b/src/core/MOM_check_scaling.F90 @@ -28,19 +28,23 @@ subroutine check_MOM6_scaling_factors(GV, US) type(unit_scale_type), intent(in) :: US !< A dimensional unit scaling type !

This code was an attempt from 2015 to define an appropriate hybrid vertical coordinate for global climate modeling, but it never worked very well (usually falling apart in the second year), and it has not been used in any publication or active model for many years. The test case that exercised this coordinate in the MOM6-examples test suite is also being removed via MOM6-examples PR #388. The coord_SLight code is being eliminated altogether now to simplify the MOM6 code base and reduce the volume of untested and unused code. All answers in all known MOM6 configurations in active use are bitwise identical, although there is a remote chance that someone somewhere might be using the SLIGHT coordinate. --- src/ALE/MOM_regridding.F90 | 188 +----- src/ALE/coord_slight.F90 | 733 ------------------------ src/ALE/regrid_consts.F90 | 6 - src/diagnostics/MOM_obsolete_params.F90 | 8 + src/framework/MOM_diag_remap.F90 | 4 - 5 files changed, 18 insertions(+), 921 deletions(-) delete mode 100644 src/ALE/coord_slight.F90 diff --git a/src/ALE/MOM_regridding.F90 b/src/ALE/MOM_regridding.F90 index 5e46b8d1f6..b9d74c01a2 100644 --- a/src/ALE/MOM_regridding.F90 +++ b/src/ALE/MOM_regridding.F90 @@ -22,7 +22,7 @@ module MOM_regridding use regrid_consts, only : REGRIDDING_LAYER, REGRIDDING_ZSTAR use regrid_consts, only : REGRIDDING_RHO, REGRIDDING_SIGMA use regrid_consts, only : REGRIDDING_ARBITRARY, REGRIDDING_SIGMA_SHELF_ZSTAR -use regrid_consts, only : REGRIDDING_HYCOM1, REGRIDDING_HYBGEN, REGRIDDING_SLIGHT, REGRIDDING_ADAPTIVE +use regrid_consts, only : REGRIDDING_HYCOM1, REGRIDDING_HYBGEN, REGRIDDING_ADAPTIVE use regrid_interp, only : interp_CS_type, set_interp_scheme, set_interp_extrap use coord_zlike, only : init_coord_zlike, zlike_CS, set_zlike_params, build_zstar_column, end_coord_zlike @@ -30,7 +30,6 @@ module MOM_regridding use coord_rho, only : init_coord_rho, rho_CS, set_rho_params, build_rho_column, end_coord_rho use coord_rho, only : old_inflate_layers_1d use coord_hycom, only : init_coord_hycom, hycom_CS, set_hycom_params, build_hycom1_column, end_coord_hycom -use coord_slight, only : init_coord_slight, slight_CS, set_slight_params, build_slight_column, end_coord_slight use coord_adapt, only : init_coord_adapt, adapt_CS, set_adapt_params, build_adapt_column, end_coord_adapt use MOM_hybgen_regrid, only : hybgen_regrid, hybgen_regrid_CS, init_hybgen_regrid, end_hybgen_regrid use MOM_hybgen_regrid, only : write_Hybgen_coord_file @@ -61,7 +60,7 @@ module MOM_regridding !!

It uses different inputs, different parameters, filters the BLD differently, - Renamed mixedlayer_restrat_general to mxiedlayer_restrat_OM4 to better distinguish the two versions. - Added function rmean2ts to extend the resetting running-mean time filter used in OM4 to use different time scales when growing or decaying. While mathematically the same in the limit of a zero "growing" time-scale, the implementation differs in the use of a reciprocal instead of division so was not added to the OM4 version. - Updated module documentation Co-authored-by: Abigail Bodner --- src/core/MOM.F90 | 2 +- src/core/MOM_variables.F90 | 4 +- .../lateral/MOM_mixed_layer_restrat.F90 | 698 ++++++++++++++++-- .../vertical/MOM_diabatic_driver.F90 | 20 + .../vertical/MOM_set_viscosity.F90 | 11 +- 5 files changed, 661 insertions(+), 74 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 84eb5fc90a..54695e6636 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -1263,7 +1263,7 @@ subroutine step_MOM_dynamics(forces, p_surf_begin, p_surf_end, dt, dt_thermo, & endif call cpu_clock_begin(id_clock_ml_restrat) call mixedlayer_restrat(h, CS%uhtr, CS%vhtr, CS%tv, forces, dt, CS%visc%MLD, & - CS%VarMix, G, GV, US, CS%mixedlayer_restrat_CSp) + CS%visc%sfc_buoy_flx, CS%VarMix, G, GV, US, CS%mixedlayer_restrat_CSp) call cpu_clock_end(id_clock_ml_restrat) call pass_var(h, G%Domain, clock=id_clock_pass, halo=max(2,CS%cont_stencil)) if (CS%debug) then diff --git a/src/core/MOM_variables.F90 b/src/core/MOM_variables.F90 index 6aa94f584f..5efb02fe44 100644 --- a/src/core/MOM_variables.F90 +++ b/src/core/MOM_variables.F90 @@ -257,8 +257,8 @@ module MOM_variables Ray_v !< The Rayleigh drag velocity to be applied to each layer at v-points [Z T-1 ~> m s-1]. !

This does not change the diagnostic itself, but it changes the order of the rescaling and the vertical remapping of this diagnostic onto other coordinates (like z) or spatial averaging of this diagnostic, which can change values in the last bits for this diagnostic for Boussinesq models (but not for non-Boussinesq models, for which the conversion factor is an integer power of 2). As a result some of the diagnostics derived from masscello can differ and this commit nominally fails the TC testing for reproducibility across code versions. All solutions and primary diagnostics, however, are bitwise identical, and even the derived diagnostic calculations are mathematically equivalent. --- src/diagnostics/MOM_diagnostics.F90 | 9 ++------- 1 file changed, 2 insertions(+), 7 deletions(-) diff --git a/src/diagnostics/MOM_diagnostics.F90 b/src/diagnostics/MOM_diagnostics.F90 index 4f5e95cc26..cf8b042c14 100644 --- a/src/diagnostics/MOM_diagnostics.F90 +++ b/src/diagnostics/MOM_diagnostics.F90 @@ -324,12 +324,7 @@ subroutine calculate_diagnostic_fields(u, v, h, uh, vh, tv, ADp, CDp, p_surf, & ! mass per area of grid cell (for Boussinesq, use Rho0) if (CS%id_masscello > 0) then - do k=1,nz ; do j=js,je ; do i=is,ie - work_3d(i,j,k) = GV%H_to_kg_m2*h(i,j,k) - enddo ; enddo ; enddo - call post_data(CS%id_masscello, work_3d, CS%diag) - !### If the registration call has conversion=GV%H_to_kg_m2, the mathematically equivalent form would be: - ! call post_data(CS%id_masscello, h, CS%diag) + call post_data(CS%id_masscello, h, CS%diag) endif ! mass of liquid ocean (for Bouss, use Rho0).

This rescaling within the restart files has not been used in the code since March, 2022, and the model will work with older restart files provided that they did not use dimensional rescaling, and even if they did they can be converted not to use rescaling with a short run with the older code that created them. Also removed the publicly visible routines fix_restart_scaling and eliminated the m_to_H_restart element of the verticalGrid_type; in any cases of non-standard code using this element, it should be replaced with 1.0. The various US%..._restart elements and fix_restart_unit_scaling are being retained for now because they are still being used in the SIS2 code. These changes significantly simplify the code, and they lead to a handful of constants that are always 1 not being included in the MOM6 restart files. All answers are bitwise identical, but a publicly visible interface has been eliminated, as has been an element (GV%m_to_H_restart) of a transparent type. --- src/core/MOM.F90 | 67 +------------------ src/core/MOM_barotropic.F90 | 14 ---- src/core/MOM_dynamics_split_RK2.F90 | 36 ---------- src/core/MOM_verticalGrid.F90 | 18 +---- src/framework/MOM_unit_scaling.F90 | 22 +++--- src/ice_shelf/MOM_ice_shelf.F90 | 34 ---------- src/ice_shelf/MOM_ice_shelf_dynamics.F90 | 19 ------ .../MOM_state_initialization.F90 | 12 ---- src/parameterizations/lateral/MOM_MEKE.F90 | 45 ------------- .../lateral/MOM_mixed_layer_restrat.F90 | 22 ------ .../vertical/MOM_set_viscosity.F90 | 42 ------------ src/tracer/boundary_impulse_tracer.F90 | 4 -- src/user/MOM_controlled_forcing.F90 | 49 -------------- 13 files changed, 16 insertions(+), 368 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index c8573a2c06..6cef9a6b30 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -135,14 +135,12 @@ module MOM use MOM_tracer_flow_control, only : tracer_flow_control_init, call_tracer_surface_state use MOM_tracer_flow_control, only : tracer_flow_control_end, call_tracer_register_obc_segments use MOM_transcribe_grid, only : copy_dyngrid_to_MOM_grid, copy_MOM_grid_to_dyngrid -use MOM_unit_scaling, only : unit_scale_type, unit_scaling_init -use MOM_unit_scaling, only : unit_scaling_end, fix_restart_unit_scaling +use MOM_unit_scaling, only : unit_scale_type, unit_scaling_init, unit_scaling_end use MOM_variables, only : surface, allocate_surface_state, deallocate_surface_state use MOM_variables, only : thermo_var_ptrs, vertvisc_type, porous_barrier_type use MOM_variables, only : accel_diag_ptrs, cont_diag_ptrs, ocean_internal_state use MOM_variables, only : rotate_surface_state use MOM_verticalGrid, only : verticalGrid_type, verticalGridInit, verticalGridEnd -use MOM_verticalGrid, only : fix_restart_scaling use MOM_verticalGrid, only : get_thickness_units, get_flux_units, get_tr_flux_units use MOM_wave_interface, only : wave_parameters_CS, waves_end, waves_register_restarts use MOM_wave_interface, only : Update_Stokes_Drift @@ -1978,7 +1976,6 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, restart_CSp, & real :: conv2watt !

From f48bce7021718e9d3868082bffb517ab3e71e4d3 Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Wed, 8 Feb 2023 10:24:38 -0500 Subject: [PATCH 0670/1329] +Add MOM_EOS_Wright_Full Added the new module MOM_EOS_Wright_full to enable the use of the version of the Wright equation of state that has been fit over the larger range of temperatures (-2 degC to 40 degC), salinities (0 psu to 40 psu) and pressures (0 dbar to 10000 dbar), than the does the restricted range fit in MOM_EOS_Wright, which had been fit over the range of (-2 degC to 30 degC), (28 psu to 38 psu) and (0 to 5000 dbar). Comments have been added to both modules to clearly document the range of properties over which they have been fitted. The new equation of state is enabled by setting EQN_OF_STATE = "WRIGHT_FULL". In addition, the default values for TFREEZE_FORM and EOS_QUADRATURE were changed depending on the equation of state to avoid having defaults that lead to fatal errors. All answers are bitwise identical in any cases that currently work, but there are new entries in the MOM_parameter_doc files. For now, only the coefficients have been changed between MOM_EOS_Wright and MOM_EOS_Wright_full, but this means that it does not yet have all of the parentheses that it should, as github.com/mom-ocean/MOM6/issues/1331 discusses. A follow up PR should add appropriate self-consistency and reference value checks (with a tolerance) for the various EOS routines, and then add enough parentheses to specify the order of arithmetic and hopefully enhance the accuracy. Ideally this can be done with the new equation of state before it starts to be widely used, so that we can avoid needing a extra code to reproduce the older answers. ---

In doing this, an effort was made to add the smallest terms first to reduce the impact of roundoff. In some cases, the code was deliberately rearranged to cancel out the leading order terms more completely. In addition, two bugs had been identified in calculate_density_second_derivs_wright_full. These were corrected and the entire routine substantially refactored with renamed variables to make the derivation easier to follow and verify. Apart from the bug corrections in the calculation of drho_dt_dt and drho_dt_dp, the changes in the expressions are mathematically equivalent, but they might make the model less noisy in some cases by reducing contributions from round-off errors. Also added comments highlighting two bugs in the drho_dt_dt and drho_dt_dp calculations in calculate_density_second_derivs_wright in the original MOM_EOS_Wright code, but did not correct them to preserve the previous answers. --- src/equation_of_state/MOM_EOS_Wright.F90 | 3 +- src/equation_of_state/MOM_EOS_Wright_full.F90 | 191 +++++++++--------- 2 files changed, 102 insertions(+), 92 deletions(-) diff --git a/src/equation_of_state/MOM_EOS_Wright.F90 b/src/equation_of_state/MOM_EOS_Wright.F90 index 36180d14e8..5fd67dcfb3 100644 --- a/src/equation_of_state/MOM_EOS_Wright.F90 +++ b/src/equation_of_state/MOM_EOS_Wright.F90 @@ -300,7 +300,7 @@ subroutine calculate_density_second_derivs_array_wright(T, S, P, drho_ds_ds, drh do j = start,start+npts-1 z0 = T(j)*(b1 + b5*S(j) + T(j)*(b2 + b3*T(j))) z1 = (b0 + P(j) + b4*S(j) + z0) - z3 = (b1 + b5*S(j) + T(j)*(2.*b2 + 2.*b3*T(j))) + z3 = (b1 + b5*S(j) + T(j)*(2.*b2 + 2.*b3*T(j))) !

From f650db6e6aad83f925f29ab129618c5315b34e20 Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Mon, 13 Feb 2023 08:13:28 -0500 Subject: [PATCH 0673/1329] +Created the new module MOM_EOS_Wright_red Created a new module, MOM_EOS_Wright_red, that uses the reduced range fit coefficients from the Wright EOS paper, but uses the parentheses, expressions and bug fixes that are now in MOM_EOS_Wright_full. To use this new module, set EQN_OF_STATE="WRIGHT_RED". This new form is mathematically equivalent using EQN_OF_STATE="WRIGHT" (apart from correcting the bugs in the calculations of drho_dt_dt and drho_dt_dp), but the order of arithmetic is different, so the answers will differ. This change is probably as close as we can come to addressing the issues discussed at github.com/mom-ocean/MOM6/issues/1331, so that issue should be closed once this commit is merged onto the main branch. Also corrected some misleading error messages in MOM_EOS and modified the code to properly handle the case for equations of state (like NEMO and UNESCO) that do not have a scalar form of calculate_density_derivs, but do have an array form. By default, all answers are bitwise identical. --- src/equation_of_state/MOM_EOS.F90 | 137 ++- src/equation_of_state/MOM_EOS_Wright_red.F90 | 963 +++++++++++++++++++ 2 files changed, 1081 insertions(+), 19 deletions(-) create mode 100644 src/equation_of_state/MOM_EOS_Wright_red.F90 diff --git a/src/equation_of_state/MOM_EOS.F90 b/src/equation_of_state/MOM_EOS.F90 index a49cc39058..6c8900172f 100644 --- a/src/equation_of_state/MOM_EOS.F90 +++ b/src/equation_of_state/MOM_EOS.F90 @@ -18,6 +18,11 @@ module MOM_EOS use MOM_EOS_Wright_full, only : calculate_specvol_derivs_wright_full, int_density_dz_wright_full use MOM_EOS_Wright_full, only : calculate_compress_wright_full, int_spec_vol_dp_wright_full use MOM_EOS_Wright_full, only : calculate_density_second_derivs_wright_full +use MOM_EOS_Wright_red, only : calculate_density_wright_red, calculate_spec_vol_wright_red +use MOM_EOS_Wright_red, only : calculate_density_derivs_wright_red +use MOM_EOS_Wright_red, only : calculate_specvol_derivs_wright_red, int_density_dz_wright_red +use MOM_EOS_Wright_red, only : calculate_compress_wright_red, int_spec_vol_dp_wright_red +use MOM_EOS_Wright_red, only : calculate_density_second_derivs_wright_red use MOM_EOS_UNESCO, only : calculate_density_unesco, calculate_spec_vol_unesco use MOM_EOS_UNESCO, only : calculate_density_derivs_unesco, calculate_density_unesco use MOM_EOS_UNESCO, only : calculate_compress_unesco @@ -131,7 +136,7 @@ module MOM_EOS real :: dTFr_dp !< The derivative of freezing point with pressure [degC Pa-1] !

This bug will cause any configurations with EQN_OF_STATE="LINEAR" and BOUSSINESQ=False (neither of which is the default value) to have the wrong sign of the pressure gradients and other serious problems, like implausible sea surface and internal interface heights. This combination of parameters would never be used in a realistic ocean model. There are no impacted cases in any of the MOM6-examples tests cases, nor those used in the ESMG or dev/NCAR test suites, and it is very unlikely that any such case would work at all. This bug was present in the original version of the calculate_spec_vol_linear routines, but it was only discovered after the implementation of the comprehensive equation of state unit testing. This will change answers in configurations that could not have worked as viable ocean models, but answers are not impacted in any known configuration, and all solutions in test cases are bitwise identical. --- src/equation_of_state/MOM_EOS_linear.F90 | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/equation_of_state/MOM_EOS_linear.F90 b/src/equation_of_state/MOM_EOS_linear.F90 index dd45e6cd81..dc3a5f59b2 100644 --- a/src/equation_of_state/MOM_EOS_linear.F90 +++ b/src/equation_of_state/MOM_EOS_linear.F90 @@ -119,7 +119,7 @@ subroutine calculate_spec_vol_scalar_linear(T, S, pressure, specvol, & real, optional, intent(in) :: spv_ref !< A reference specific volume [m3 kg-1]. if (present(spv_ref)) then - specvol = ((1.0 - Rho_T0_S0*spv_ref) + spv_ref*(dRho_dT*T + dRho_dS*S)) / & + specvol = ((1.0 - Rho_T0_S0*spv_ref) - spv_ref*(dRho_dT*T + dRho_dS*S)) / & ( Rho_T0_S0 + (dRho_dT*T + dRho_dS*S)) else specvol = 1.0 / ( Rho_T0_S0 + (dRho_dT*T + dRho_dS*S)) @@ -148,7 +148,7 @@ subroutine calculate_spec_vol_array_linear(T, S, pressure, specvol, start, npts, integer :: j if (present(spv_ref)) then ; do j=start,start+npts-1 - specvol(j) = ((1.0 - Rho_T0_S0*spv_ref) + spv_ref*(dRho_dT*T(j) + dRho_dS*S(j))) / & + specvol(j) = ((1.0 - Rho_T0_S0*spv_ref) - spv_ref*(dRho_dT*T(j) + dRho_dS*S(j))) / & ( Rho_T0_S0 + (dRho_dT*T(j) + dRho_dS*S(j))) enddo ; else ; do j=start,start+npts-1 specvol(j) = 1.0 / ( Rho_T0_S0 + (dRho_dT*T(j) + dRho_dS*S(j))) From 71e0bb7e673e4b93ea3ff727491c58505b7dc7bd Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Tue, 14 Feb 2023 16:47:31 -0500 Subject: [PATCH 0675/1329] +Add EOS_unit_tests Added the new publicly visible function EOS_unit_tests, along with a call to it from inside of unit_tests. These tests evaluate check values for density and assess the consistency of expressions for variables that can be derived from density with finite-difference estimates of the same variables. These tests reveal inconsistencies or omissions with several of the options for the equation of state. The EOS self-consistency tests that are failing are commented out for now, so that this redacted unit test passes.

Previously these had only been consistent to about 7 decimal places, and hence the EOS unit tests were failing for the NEMO equation of state. - Added new public interfaces to calculate_density_second_derivs_NEMO, which had previously been missing. - Added code for calculate_compress_nemo that is explicitly derived from the NEMO EOS. The previous version of calculate_compress_nemo had worked only approximately via a call to the gsw package With these changes, the NEMO EOS routines are now passing the consistency testing in the EOS unit tests. Answers will change for configurations that use the NEMO EOS to calculate any derivatives, and there are new public interfaces, but it does not appear that the NEMO equation of state is in use yet, at least it is not being used at EMC, FSU, GFDL, NASA GSFC, NCAR or in the ESMG configurations.

Also added the new runtime parameter USE_WRIGHT_2ND_DERIV_BUG to indicate that the older (buggy) version of calculate_density_second_derivs_wright is to be used. Most configurations will not be impacted, but by default answers will change with configurations that use the Wright equation of state and one of the Stanley or similar nonlinear EOS parameterizations, unless USE_WRIGHT_2ND_DERIV_BUG is explicitly set to True. This commit also activates the self-consistency unit testing with the Wright equation of state (now that it passes) and limited unit testing of the TEOS-10 equation of state, omitting the second derivative calculations, one of which is failing (the second derivative of density with salinity and pressure) due to a bug in the TEOS10/gsw code.

Also added comments to better describe the references for these algorithms. Although the revised expressions are all mathematically equivalent, this commit will change answers for any cases that use EQN_OF_STATE = "UNESCO". However, it is believed based on a survey of the MOM6 community that there are no active configurations that use this equation of state. --- src/equation_of_state/MOM_EOS_UNESCO.F90 | 402 +++++++++++------------ 1 file changed, 184 insertions(+), 218 deletions(-) diff --git a/src/equation_of_state/MOM_EOS_UNESCO.F90 b/src/equation_of_state/MOM_EOS_UNESCO.F90 index 1c445e3453..b6398e07e2 100644 --- a/src/equation_of_state/MOM_EOS_UNESCO.F90 +++ b/src/equation_of_state/MOM_EOS_UNESCO.F90 @@ -52,8 +52,7 @@ module MOM_EOS_UNESCO !

A number of internal variables were also renamed for greater clarity, and a number of comments were revised to better describe the references for these algorithms.. Although the revised expressions are all mathematically equivalent, this commit will change answers for any cases that use EQN_OF_STATE = "NEMO". However, there is another recent commit to this file that also changes answers (specifically the density derivatives) with this equation of state, and it is believed based on a survey of the MOM6 community that there are no active configurations that use this equation of state. --- src/equation_of_state/MOM_EOS_NEMO.F90 | 508 ++++++++++++------------- 1 file changed, 238 insertions(+), 270 deletions(-) diff --git a/src/equation_of_state/MOM_EOS_NEMO.F90 b/src/equation_of_state/MOM_EOS_NEMO.F90 index b0515ac768..33ea84721f 100644 --- a/src/equation_of_state/MOM_EOS_NEMO.F90 +++ b/src/equation_of_state/MOM_EOS_NEMO.F90 @@ -14,38 +14,38 @@ module MOM_EOS_NEMO !> Compute the in situ density of sea water [kg m-3], or its anomaly with respect to !! a reference density, from absolute salinity [g kg-1], conservative temperature [degC], -!! and pressure [Pa], using the expressions derived for use with NEMO +!! and pressure [Pa], using the expressions for density from Roquet et al.

(2015). This equation of state has also been added to MOM_EOS, where it is enabled by setting EQN_OF_STATE="ROQUET_SPV". Two other new valid settings have been added to EQN_OF_STATE, "ROQUET_RHO" and "JACKETT_MCD", which synonymous with "NEMO" and "UNESCO" respectively, but more accurately reflect the publications that describe these fits to the equation of state. The EoS unit tests are being called for the new equation of state (it passes). By default, all answers are bitwise identical, but there are numerous new publicly visible interfaces. --- src/equation_of_state/MOM_EOS.F90 | 134 +++- src/equation_of_state/MOM_EOS_Roquet_SpV.F90 |

(2006). This uses potential temperature and practical salinity as state variables, but with a fit to more up-to-date observational data than Wright (1997) or UNESCO / Jackett and McDougall (1995). This equation of state has also been added to MOM_EOS, where it is enabled by setting EQN_OF_STATE="JACKETT_06". The EoS unit tests are being called for the new equation of state (it passes). This commit also adds slightly more output from successful EoS unit tests when run with typical levels of verbosity. By default, all answers are bitwise identical, but there are numerous new publicly visible interfaces. --- src/equation_of_state/MOM_EOS.F90 | 116 +++- src/equation_of_state/MOM_EOS_Jackett06.F90 |

Also added some missing parentheses elsewhere in this module so that the answers will be invariant to complier version and optimization levels. Also revised the internal nomenclature of the parameters in this module to follow the conventions of the other EOS modules. Although the revised expressions are mathematically equivalent, this commit will change answers for any cases that use EQN_OF_STATE = "UNESCO". However, it is believed based on a survey of the MOM6 community that there are no active configurations that use this equation of state. There is a new publicly visible routine. --- src/equation_of_state/MOM_EOS.F90 | 17 +- src/equation_of_state/MOM_EOS_UNESCO.F90 | 335 ++++++++++++++--------- 2 files changed, 204 insertions(+), 148 deletions(-) diff --git a/src/equation_of_state/MOM_EOS.F90 b/src/equation_of_state/MOM_EOS.F90 index 1640fb6e0e..f79d304dfc 100644 --- a/src/equation_of_state/MOM_EOS.F90 +++ b/src/equation_of_state/MOM_EOS.F90 @@ -27,7 +27,7 @@ module MOM_EOS use MOM_EOS_Jackett06, only : calculate_density_derivs_Jackett06, calculate_specvol_derivs_Jackett06 use MOM_EOS_Jackett06, only : calculate_compress_Jackett06, calculate_density_second_derivs_Jackett06 use MOM_EOS_UNESCO, only : calculate_density_unesco, calculate_spec_vol_unesco -use MOM_EOS_UNESCO, only : calculate_density_derivs_unesco, calculate_density_unesco +use MOM_EOS_UNESCO, only : calculate_density_derivs_unesco, calculate_specvol_derivs_UNESCO use MOM_EOS_UNESCO, only : calculate_density_second_derivs_UNESCO, calculate_compress_unesco use MOM_EOS_NEMO, only : calculate_density_nemo use MOM_EOS_NEMO, only : calculate_density_derivs_nemo @@ -331,7 +331,7 @@ subroutine calculate_density_array(T, S, pressure, rho, start, npts, EOS, rho_re call calculate_density_linear(T, S, pressure, rho, start, npts, & EOS%Rho_T0_S0, EOS%dRho_dT, EOS%dRho_dS, rho_ref) case (EOS_UNESCO) - call calculate_density_unesco(T, S, pressure, rho, start, npts, rho_ref) + call calculate_density_UNESCO(T, S, pressure, rho, start, npts, rho_ref) case (EOS_WRIGHT) call calculate_density_wright(T, S, pressure, rho, start, npts, rho_ref) case (EOS_WRIGHT_FULL) @@ -636,7 +636,7 @@ subroutine calculate_spec_vol_array(T, S, pressure, specvol, start, npts, EOS, s call calculate_spec_vol_linear(T, S, pressure, specvol, start, npts, & EOS%rho_T0_S0, EOS%drho_dT, EOS%drho_dS, spv_ref) case (EOS_UNESCO) - call calculate_spec_vol_unesco(T, S, pressure, specvol, start, npts, spv_ref) + call calculate_spec_vol_UNESCO(T, S, pressure, specvol, start, npts, spv_ref) case (EOS_WRIGHT) call calculate_spec_vol_wright(T, S, pressure, specvol, start, npts, spv_ref) case (EOS_WRIGHT_FULL) @@ -931,7 +931,7 @@ subroutine calculate_density_derivs_array(T, S, pressure, drho_dT, drho_dS, star call calculate_density_derivs_linear(T, S, pressure, drho_dT, drho_dS, EOS%Rho_T0_S0, & EOS%dRho_dT, EOS%dRho_dS, start, npts) case (EOS_UNESCO) - call calculate_density_derivs_unesco(T, S, pressure, drho_dT, drho_dS, start, npts) + call calculate_density_derivs_UNESCO(T, S, pressure, drho_dT, drho_dS, start, npts) case (EOS_WRIGHT) call calculate_density_derivs_wright(T, S, pressure, drho_dT, drho_dS, start, npts) case (EOS_WRIGHT_FULL) @@ -1333,12 +1333,7 @@ subroutine calculate_spec_vol_derivs_array(T, S, pressure, dSV_dT, dSV_dS, start call calculate_specvol_derivs_linear(T, S, pressure, dSV_dT, dSV_dS, start, & npts, EOS%Rho_T0_S0, EOS%dRho_dT, EOS%dRho_dS) case (EOS_UNESCO) - call calculate_density_unesco(T, S, pressure, rho, start, npts) - call calculate_density_derivs_unesco(T, S, pressure, drho_dT, drho_dS, start, npts) - do j=start,start+npts-1 - dSV_dT(j) = -dRho_DT(j)/(rho(j)**2) - dSV_dS(j) = -dRho_DS(j)/(rho(j)**2) - enddo + call calculate_specvol_derivs_UNESCO(T, S, pressure, dSV_dT, dSV_dS, start, npts) case (EOS_WRIGHT) call calculate_specvol_derivs_wright(T, S, pressure, dSV_dT, dSV_dS, start, npts) case (EOS_WRIGHT_FULL) @@ -1455,7 +1450,7 @@ subroutine calculate_compress_1d(T, S, pressure, rho, drho_dp, EOS, dom) call calculate_compress_linear(Ta, Sa, pres, rho, drho_dp, is, npts, & EOS%Rho_T0_S0, EOS%dRho_dT, EOS%dRho_dS) case (EOS_UNESCO) - call calculate_compress_unesco(Ta, Sa, pres, rho, drho_dp, is, npts) + call calculate_compress_UNESCO(Ta, Sa, pres, rho, drho_dp, is, npts) case (EOS_WRIGHT) call calculate_compress_wright(Ta, Sa, pres, rho, drho_dp, is, npts) case (EOS_WRIGHT_FULL) diff --git a/src/equation_of_state/MOM_EOS_UNESCO.F90 b/src/equation_of_state/MOM_EOS_UNESCO.F90 index b6398e07e2..ae9cf72aaa 100644 --- a/src/equation_of_state/MOM_EOS_UNESCO.F90 +++ b/src/equation_of_state/MOM_EOS_UNESCO.F90 @@ -6,7 +6,7 @@ module MOM_EOS_UNESCO implicit none ; private public calculate_compress_UNESCO, calculate_density_UNESCO, calculate_spec_vol_UNESCO -public calculate_density_derivs_UNESCO +public calculate_density_derivs_UNESCO, calculate_specvol_derivs_UNESCO public calculate_density_scalar_UNESCO, calculate_density_array_UNESCO public calculate_density_second_derivs_UNESCO @@ -32,57 +32,56 @@ module MOM_EOS_UNESCO !>@{ Parameters in the UNESCO equation of state, as published in appendix A3 of Gill, 1982. -!

This is also tested for in test_EOS_consistency to indicate whether a test value is outside of the fit range, but the real purpose will be to flag and then figure out how to deal with the case when the ocean model is called with properties for which the equation of state is not valid. Note that as with all polynomial or other functional fits, extrapolating far outside of the fit range is likely to lead to bad values, but things may not be so bad for values that are only slightly outside of this range. However the question of how far out of the fit range these EoS expressions become inappropriate for each of temperature, salinity and pressure is as yet unresolved. All answers and output are bitwise identical, but there are 10 new public interfaces. --- src/equation_of_state/MOM_EOS.F90 | 78 ++++++++++++++++++- src/equation_of_state/MOM_EOS_Jackett06.F90 | 31 +++++++- src/equation_of_state/MOM_EOS_NEMO.F90 | 22 +++++- src/equation_of_state/MOM_EOS_Roquet_SpV.F90 | 22 +++++- src/equation_of_state/MOM_EOS_TEOS10.F90 | 26 ++++++- src/equation_of_state/MOM_EOS_UNESCO.F90 | 22 +++++- src/equation_of_state/MOM_EOS_Wright.F90 | 21 +++++ src/equation_of_state/MOM_EOS_Wright_full.F90 | 22 +++++- src/equation_of_state/MOM_EOS_Wright_red.F90 | 22 +++++- src/equation_of_state/MOM_EOS_linear.F90 | 22 +++++- 10 files changed, 275 insertions(+), 13 deletions(-) diff --git a/src/equation_of_state/MOM_EOS.F90 b/src/equation_of_state/MOM_EOS.F90 index f79d304dfc..1628ceb594 100644 --- a/src/equation_of_state/MOM_EOS.F90 +++ b/src/equation_of_state/MOM_EOS.F90 @@ -6,38 +6,46 @@ module MOM_EOS use MOM_EOS_linear, only : calculate_density_linear, calculate_spec_vol_linear use MOM_EOS_linear, only : calculate_density_derivs_linear use MOM_EOS_linear, only : calculate_specvol_derivs_linear, int_density_dz_linear -use MOM_EOS_linear, only : calculate_density_second_derivs_linear +use MOM_EOS_linear, only : calculate_density_second_derivs_linear, EoS_fit_range_linear use MOM_EOS_linear, only : calculate_compress_linear, int_spec_vol_dp_linear use MOM_EOS_Wright, only : calculate_density_wright, calculate_spec_vol_wright use MOM_EOS_Wright, only : calculate_density_derivs_wright use MOM_EOS_Wright, only : calculate_specvol_derivs_wright, int_density_dz_wright use MOM_EOS_Wright, only : calculate_compress_wright, int_spec_vol_dp_wright use MOM_EOS_Wright, only : calculate_density_second_derivs_wright, calc_density_second_derivs_wright_buggy +use MOM_EOS_Wright, only : EoS_fit_range_Wright use MOM_EOS_Wright_full, only : calculate_density_wright_full, calculate_spec_vol_wright_full use MOM_EOS_Wright_full, only : calculate_density_derivs_wright_full use MOM_EOS_Wright_full, only : calculate_specvol_derivs_wright_full, int_density_dz_wright_full use MOM_EOS_Wright_full, only : calculate_compress_wright_full, int_spec_vol_dp_wright_full use MOM_EOS_Wright_full, only : calculate_density_second_derivs_wright_full +use MOM_EOS_Wright_full, only : EoS_fit_range_Wright_full use MOM_EOS_Wright_red, only : calculate_density_wright_red, calculate_spec_vol_wright_red use MOM_EOS_Wright_red, only : calculate_density_derivs_wright_red use MOM_EOS_Wright_red, only : calculate_specvol_derivs_wright_red, int_density_dz_wright_red use MOM_EOS_Wright_red, only : calculate_compress_wright_red, int_spec_vol_dp_wright_red use MOM_EOS_Wright_red, only : calculate_density_second_derivs_wright_red +use MOM_EOS_Wright_red, only : EoS_fit_range_Wright_red use MOM_EOS_Jackett06, only : calculate_density_Jackett06, calculate_spec_vol_Jackett06 use MOM_EOS_Jackett06, only : calculate_density_derivs_Jackett06, calculate_specvol_derivs_Jackett06 use MOM_EOS_Jackett06, only : calculate_compress_Jackett06, calculate_density_second_derivs_Jackett06 +use MOM_EOS_Jackett06, only : EoS_fit_range_Jackett06 use MOM_EOS_UNESCO, only : calculate_density_unesco, calculate_spec_vol_unesco use MOM_EOS_UNESCO, only : calculate_density_derivs_unesco, calculate_specvol_derivs_UNESCO use MOM_EOS_UNESCO, only : calculate_density_second_derivs_UNESCO, calculate_compress_unesco +use MOM_EOS_UNESCO, only : EoS_fit_range_UNESCO use MOM_EOS_NEMO, only : calculate_density_nemo use MOM_EOS_NEMO, only : calculate_density_derivs_nemo use MOM_EOS_NEMO, only : calculate_density_second_derivs_NEMO, calculate_compress_nemo +use MOM_EOS_NEMO, only : EoS_fit_range_NEMO use MOM_EOS_Roquet_SpV, only : calculate_density_Roquet_SpV, calculate_spec_vol_Roquet_SpV use MOM_EOS_Roquet_SpV, only : calculate_density_derivs_Roquet_SpV, calculate_specvol_derivs_Roquet_SpV use MOM_EOS_Roquet_SpV, only : calculate_compress_Roquet_SpV, calculate_density_second_derivs_Roquet_SpV +use MOM_EOS_Roquet_SpV, only : EoS_fit_range_Roquet_SpV use MOM_EOS_TEOS10, only : calculate_density_teos10, calculate_spec_vol_teos10 use MOM_EOS_TEOS10, only : calculate_density_derivs_teos10, calculate_specvol_derivs_teos10 use MOM_EOS_TEOS10, only : calculate_density_second_derivs_teos10, calculate_compress_teos10 +use MOM_EOS_TEOS10, only : EoS_fit_range_TEOS10 use MOM_EOS_TEOS10, only : gsw_sp_from_sr, gsw_pt_from_ct use MOM_TFreeze, only : calculate_TFreeze_linear, calculate_TFreeze_Millero use MOM_TFreeze, only : calculate_TFreeze_teos10 @@ -57,6 +65,7 @@ module MOM_EOS public EOS_manual_init public EOS_quadrature public EOS_use_linear +public EOS_fit_range public EOS_unit_tests public analytic_int_density_dz public analytic_int_specific_vol_dp @@ -1506,6 +1515,43 @@ subroutine calculate_compress_scalar(T, S, pressure, rho, drho_dp, EOS) end subroutine calculate_compress_scalar +!> Return the range of temperatures, salinities and pressures for which the equation of state that +!!

However, the coefficients are still set using the values directly copied from that paper, but rescaled where they are declared as parameters, enabling (or requiring) compilers to precalculate them during compilation. These changes are mathematically equivalent but will change answers at roundoff with these two equations of state, but they are not believed to be in use yet. --- src/equation_of_state/MOM_EOS_Roquet_SpV.F90 | 431 +++++++++--------- src/equation_of_state/MOM_EOS_Roquet_rho.F90 | 451 ++++++++++--------- 2 files changed, 447 insertions(+), 435 deletions(-) diff --git a/src/equation_of_state/MOM_EOS_Roquet_SpV.F90 b/src/equation_of_state/MOM_EOS_Roquet_SpV.F90 index 3bad8ac579..b6133442db 100644 --- a/src/equation_of_state/MOM_EOS_Roquet_SpV.F90 +++ b/src/equation_of_state/MOM_EOS_Roquet_SpV.F90 @@ -40,145 +40,148 @@ module MOM_EOS_Roquet_Spv module procedure calculate_density_second_derivs_array_Roquet_SpV end interface calculate_density_second_derivs_Roquet_SpV -real, parameter :: Pa2db = 1.e-4 !< Conversion factor between Pa and dbar [dbar Pa-1] +real, parameter :: Pa2kb = 1.e-8 !< Conversion factor between Pa and kbar [kbar Pa-1] !>@{ Parameters in the Roquet specific volume polynomial equation of state -real, parameter :: rdeltaS = 24. !

This gives results that agrees to within about 5e-4 degC with the algorithm used by calculate_TFreeze_TEOS10, which calls the gsw TEOS10 code that does an iterative inversion of a balance of chemical potentials to find the freezing point (see the TEOS10 documentation for more details). Also added testing for the freezing point calculations to the EOS_unit tests via the new internal subroutine test_TFr_consistency. This new freezing point calculation is invoked by setting TFREEZE_FORM = TEOS_POLY. By default, all answers are bitwise identical, but there are some minor changes in the comments in some MOM_parameter_doc files, and there are several new interfaces. --- src/equation_of_state/MOM_EOS.F90 | 132 +++++++++++++++++++++++--- src/equation_of_state/MOM_TFreeze.F90 | 97 ++++++++++++++++--- 2 files changed, 204 insertions(+), 25 deletions(-) diff --git a/src/equation_of_state/MOM_EOS.F90 b/src/equation_of_state/MOM_EOS.F90 index 1a1668e63b..3da471ce7e 100644 --- a/src/equation_of_state/MOM_EOS.F90 +++ b/src/equation_of_state/MOM_EOS.F90 @@ -48,7 +48,7 @@ module MOM_EOS use MOM_EOS_TEOS10, only : EoS_fit_range_TEOS10 use MOM_EOS_TEOS10, only : gsw_sp_from_sr, gsw_pt_from_ct use MOM_TFreeze, only : calculate_TFreeze_linear, calculate_TFreeze_Millero -use MOM_TFreeze, only : calculate_TFreeze_teos10 +use MOM_TFreeze, only : calculate_TFreeze_teos10, calculate_TFreeze_TEOS_poly use MOM_error_handler, only : MOM_error, FATAL, WARNING, MOM_mesg use MOM_file_parser, only : get_param, log_version, param_file_type use MOM_hor_index, only : hor_index_type @@ -197,8 +197,11 @@ module MOM_EOS integer, parameter :: TFREEZE_LINEAR = 1 !< A named integer specifying a freezing point expression integer, parameter :: TFREEZE_MILLERO = 2 !< A named integer specifying a freezing point expression integer, parameter :: TFREEZE_TEOS10 = 3 !< A named integer specifying a freezing point expression +integer, parameter :: TFREEZE_TEOSPOLY = 4 !< A named integer specifying a freezing point expression character*(10), parameter :: TFREEZE_LINEAR_STRING = "LINEAR" !< A string for specifying the freezing point expression -character*(10), parameter :: TFREEZE_MILLERO_STRING = "MILLERO_78" !< A string for specifying +character*(10), parameter :: TFREEZE_MILLERO_STRING = "MILLERO_78" !< A string for specifying the + !! freezing point expression +character*(10), parameter :: TFREEZE_TEOSPOLY_STRING = "TEOS_POLY" !< A string for specifying the !! freezing point expression character*(10), parameter :: TFREEZE_TEOS10_STRING = "TEOS10" !< A string for specifying the freezing point expression @@ -794,6 +797,8 @@ subroutine calculate_TFreeze_scalar(S, pressure, T_fr, EOS, pres_scale, scale_fr EOS%dTFr_dS, EOS%dTFr_dp) case (TFREEZE_MILLERO) call calculate_TFreeze_Millero(S_scale*S, p_scale*pressure, T_fr) + case (TFREEZE_TEOSPOLY) + call calculate_TFreeze_TEOS_poly(S_scale*S, p_scale*pressure, T_fr) case (TFREEZE_TEOS10) call calculate_TFreeze_teos10(S_scale*S, p_scale*pressure, T_fr) case default @@ -832,6 +837,8 @@ subroutine calculate_TFreeze_array(S, pressure, T_fr, start, npts, EOS, pres_sca EOS%TFr_S0_P0, EOS%dTFr_dS, EOS%dTFr_dp) case (TFREEZE_MILLERO) call calculate_TFreeze_Millero(S, pressure, T_fr, start, npts) + case (TFREEZE_TEOSPOLY) + call calculate_TFreeze_TEOS_poly(S, pressure, T_fr, start, npts) case (TFREEZE_TEOS10) call calculate_TFreeze_teos10(S, pressure, T_fr, start, npts) case default @@ -847,6 +854,8 @@ subroutine calculate_TFreeze_array(S, pressure, T_fr, start, npts, EOS, pres_sca call calculate_TFreeze_Millero(S, pres, T_fr, start, npts) case (TFREEZE_TEOS10) call calculate_TFreeze_teos10(S, pres, T_fr, start, npts) + case (TFREEZE_TEOSPOLY) + call calculate_TFreeze_TEOS_poly(S, pres, T_fr, start, npts) case default call MOM_error(FATAL, "calculate_TFreeze_scalar: form_of_TFreeze is not valid.") end select @@ -883,6 +892,8 @@ subroutine calculate_TFreeze_1d(S, pressure, T_fr, EOS, dom) EOS%TFr_S0_P0, EOS%dTFr_dS, EOS%dTFr_dp) case (TFREEZE_MILLERO) call calculate_TFreeze_Millero(S, pressure, T_fr, is, npts) + case (TFREEZE_TEOSPOLY) + call calculate_TFreeze_TEOS_poly(S, pressure, T_fr, is, npts) case (TFREEZE_TEOS10) call calculate_TFreeze_teos10(S, pressure, T_fr, is, npts) case default @@ -899,6 +910,8 @@ subroutine calculate_TFreeze_1d(S, pressure, T_fr, EOS, dom) EOS%TFr_S0_P0, EOS%dTFr_dS, EOS%dTFr_dp) case (TFREEZE_MILLERO) call calculate_TFreeze_Millero(Sa, pres, T_fr, is, npts) + case (TFREEZE_TEOSPOLY) + call calculate_TFreeze_TEOS_poly(Sa, pres, T_fr, is, npts) case (TFREEZE_TEOS10) call calculate_TFreeze_teos10(Sa, pres, T_fr, is, npts) case default @@ -1863,13 +1876,15 @@ subroutine EOS_init(param_file, EOS, US) call get_param(param_file, mdl, "TFREEZE_FORM", tmpstr, & "TFREEZE_FORM determines which expression should be "//& "used for the freezing point.

These routines are mathematically equivalent to the TEOS-10 functions gsw_ct_from_pt and gsw_pt_from_ct, but with some refactoring and added parentheses to help ensure identical answers across compilers or levels of optimization. Also added the new subroutines pot_temp_to_cons_temp and prac_saln_to_abs_saln, and added the new optional argument use_TEOS to convert_temp_salt_for_TEOS10, and cons_temp_to_pot_temp and abs_saln_to_prac_saln. The equivalency between the new code and their gsw_ counterparts is demonstrated in new tests in the new function test_TS_conversion_consistency, which in turn is called from EOS_unit_tests. All answers are mathematically equivalent, but because of the choice to use the new code by default there could be changes at the level of roundoff in some cases that use conservative temperature as their state variable but initialize it from potential temperature. There are not any such cases yet in the MOM6-examples test suite, nor are there believed to be any such MOM6 configurations that are widely used. This commit introduces a new module and several new functions or subroutines with public interfaces. --- src/equation_of_state/MOM_EOS.F90 | 346 +++++++++++++++--- .../MOM_temperature_convert.F90 | 166 +++++++++ 2 files changed, 458 insertions(+), 54 deletions(-) create mode 100644 src/equation_of_state/MOM_temperature_convert.F90 diff --git a/src/equation_of_state/MOM_EOS.F90 b/src/equation_of_state/MOM_EOS.F90 index 3da471ce7e..04b5e74c94 100644 --- a/src/equation_of_state/MOM_EOS.F90 +++ b/src/equation_of_state/MOM_EOS.F90 @@ -46,7 +46,8 @@ module MOM_EOS use MOM_EOS_TEOS10, only : calculate_density_derivs_teos10, calculate_specvol_derivs_teos10 use MOM_EOS_TEOS10, only : calculate_density_second_derivs_teos10, calculate_compress_teos10 use MOM_EOS_TEOS10, only : EoS_fit_range_TEOS10 -use MOM_EOS_TEOS10, only : gsw_sp_from_sr, gsw_pt_from_ct +! use MOM_EOS_TEOS10, only : gsw_sp_from_sr, gsw_pt_from_ct +use MOM_temperature_convert, only : poTemp_to_consTemp, consTemp_to_poTemp use MOM_TFreeze, only : calculate_TFreeze_linear, calculate_TFreeze_Millero use MOM_TFreeze, only : calculate_TFreeze_teos10, calculate_TFreeze_TEOS_poly use MOM_error_handler, only : MOM_error, FATAL, WARNING, MOM_mesg @@ -55,6 +56,8 @@ module MOM_EOS use MOM_io, only : stdout use MOM_string_functions, only : uppercase use MOM_unit_scaling, only : unit_scale_type +use gsw_mod_toolbox, only : gsw_sp_from_sr, gsw_pt_from_ct +use gsw_mod_toolbox, only : gsw_sr_from_sp, gsw_ct_from_pt implicit none ; private @@ -1988,7 +1991,7 @@ end subroutine EOS_use_linear !> Convert T&S to Absolute Salinity and Conservative Temperature if using TEOS10 -subroutine convert_temp_salt_for_TEOS10(T, S, HI, kd, mask_z, EOS) +subroutine convert_temp_salt_for_TEOS10(T, S, HI, kd, mask_z, EOS, use_TEOS) integer, intent(in) :: kd !< The number of layers to work on type(hor_index_type), intent(in) :: HI !< The horizontal index structure real, dimension(HI%isd:HI%ied,HI%jsd:HI%jed,kd), & @@ -1998,31 +2001,42 @@ subroutine convert_temp_salt_for_TEOS10(T, S, HI, kd, mask_z, EOS) real, dimension(HI%isd:HI%ied,HI%jsd:HI%jed,kd), & intent(in) :: mask_z !< 3d mask regulating which points to convert [nondim] type(EOS_type), intent(in) :: EOS !< Equation of state structure + logical, optional, intent(in) :: use_TEOS !< If present and true, call the TEOS code to do the conversion. real :: gsw_sr_from_sp !

Calculate_density_derivs_array is the one exception is because it is being called from SIS2 and has to stay publicly visible for now. Additionally, the scalar and 1-d versions of the calculate_stanley_density routines were refactored to just use calculate_density and calculate_density_second_derivs call and avoid any EoS-specific logic, while the unused routine calculate_stanley_density_array is eliminated altogether. All answers are bitwise identical, including in extra tests that use the stanley_density routines. --- src/equation_of_state/MOM_EOS.F90 | 243 +++--------------------------- 1 file changed, 20 insertions(+), 223 deletions(-) diff --git a/src/equation_of_state/MOM_EOS.F90 b/src/equation_of_state/MOM_EOS.F90 index f056915fa0..2f2dbb6eb3 100644 --- a/src/equation_of_state/MOM_EOS.F90 +++ b/src/equation_of_state/MOM_EOS.F90 @@ -91,16 +91,14 @@ module MOM_EOS !> Calculates density of sea water from T, S and P interface calculate_density module procedure calculate_density_scalar - module procedure calculate_density_array module procedure calculate_density_1d module procedure calculate_stanley_density_scalar - module procedure calculate_stanley_density_array module procedure calculate_stanley_density_1d end interface calculate_density !> Calculates specific volume of sea water from T, S and P interface calculate_spec_vol - module procedure calc_spec_vol_scalar, calculate_spec_vol_array + module procedure calc_spec_vol_scalar module procedure calc_spec_vol_1d end interface calculate_spec_vol @@ -112,7 +110,7 @@ module MOM_EOS !> Calculate the derivatives of specific volume with temperature and salinity from T, S, and P interface calculate_specific_vol_derivs - module procedure calc_spec_vol_derivs_1d, calculate_spec_vol_derivs_array + module procedure calc_spec_vol_derivs_1d end interface calculate_specific_vol_derivs !> Calculates the second derivatives of density with various combinations of temperature, @@ -262,60 +260,17 @@ subroutine calculate_stanley_density_scalar(T, S, pressure, Tvar, TScov, Svar, r real, optional, intent(in) :: scale !< A multiplicative factor by which to scale output density in !! combination with scaling stored in EOS [various] !

FMS2 I/O is currently restricted to files which use domains; files which do not use them are delegated to the native netCDF layer. The reasoning for this is that FMS is required to define the formatting of domain-decomposed I/O; for single-file I/O, this is not necessary. This does not remove all references to FMS1 I/O from MOM6, only those in the I/O layer. Several minor changes are included to accommodate the change: * MOM restart I/O now always reports its MOM domain. Previously, the domian was omitted when PARALLEL_RESTARTFILES was false, in order to trick FMS into handling this as a single file. We now generate a new domain with an IO layout of [1,1] when single-file restarts are requested. * The interface acceleration (g') was incorrectly set to the layer grid (Nk) rather than the interface grid (Nk+1). This did not appear to change any answers, but when Vertical_coordinate.nc was moved to the netCDF layer, it detected this error. This is fixed in this patch. --- config_src/drivers/nuopc_cap/mom_cap.F90 | 4 +- config_src/infra/FMS1/MOM_domain_infra.F90 | 15 +- config_src/infra/FMS2/MOM_domain_infra.F90 | 16 +- config_src/infra/FMS2/MOM_io_infra.F90 | 972 +++++++----------- src/ALE/MOM_regridding.F90 | 4 +- src/framework/MOM_io.F90 | 9 +- src/framework/MOM_io_file.F90 | 28 +- src/framework/MOM_restart.F90 | 4 +- .../MOM_coord_initialization.F90 | 8 +- 9 files changed, 452 insertions(+), 608 deletions(-) diff --git a/config_src/drivers/nuopc_cap/mom_cap.F90 b/config_src/drivers/nuopc_cap/mom_cap.F90 index b7d651bf55..9db4f03100 100644 --- a/config_src/drivers/nuopc_cap/mom_cap.F90 +++ b/config_src/drivers/nuopc_cap/mom_cap.F90 @@ -8,12 +8,12 @@ module MOM_cap_mod use mpp_domains_mod, only: mpp_get_ntile_count, mpp_get_pelist, mpp_get_global_domain use mpp_domains_mod, only: mpp_get_domain_npes -use MOM_time_manager, only: set_calendar_type, time_type, set_time, set_date, month_name +use MOM_time_manager, only: set_calendar_type, time_type, set_time, set_date use MOM_time_manager, only: GREGORIAN, JULIAN, NOLEAP use MOM_time_manager, only: operator( <= ), operator( < ), operator( >= ) use MOM_time_manager, only: operator( + ), operator( - ), operator( / ) use MOM_time_manager, only: operator( * ), operator( /= ), operator( > ) -use MOM_domains, only: MOM_infra_init, MOM_infra_end, num_pes, root_pe, pe_here +use MOM_domains, only: MOM_infra_init, MOM_infra_end use MOM_file_parser, only: get_param, log_version, param_file_type, close_param_file use MOM_get_input, only: get_MOM_input, directories use MOM_domains, only: pass_var diff --git a/config_src/infra/FMS1/MOM_domain_infra.F90 b/config_src/infra/FMS1/MOM_domain_infra.F90 index 470dde0848..2a00abe32d 100644 --- a/config_src/infra/FMS1/MOM_domain_infra.F90 +++ b/config_src/infra/FMS1/MOM_domain_infra.F90 @@ -1489,7 +1489,7 @@ end subroutine get_domain_components_d2D !> clone_MD_to_MD copies one MOM_domain_type into another, while allowing !! some properties of the new type to differ from the original one. subroutine clone_MD_to_MD(MD_in, MOM_dom, min_halo, halo_size, symmetric, domain_name, & - turns, refine, extra_halo) + turns, refine, extra_halo, io_layout) type(MOM_domain_type), target, intent(in) :: MD_in !< An existing MOM_domain type(MOM_domain_type), pointer :: MOM_dom !< A pointer to a MOM_domain that will be @@ -1512,6 +1512,8 @@ subroutine clone_MD_to_MD(MD_in, MOM_dom, min_halo, halo_size, symmetric, domain integer, optional, intent(in) :: refine !< A factor by which to enhance the grid resolution. integer, optional, intent(in) :: extra_halo !< An extra number of points in the halos !! compared with MD_in + integer, optional, intent(in) :: io_layout(2) + !< A user-defined IO layout to replace the domain's IO layout logical :: mask_table_exists integer, dimension(:), allocatable :: exni !

These routines are already undoing this scaling and working in height units, and it is not possible to convert thicknesses to thickness units in non-Boussinesq mode until the temperatures and salinities are also known. The routines whose argument units are altered include: - initialize_thickness_uniform - initialize_thickness_list - DOME_initialize_thickness - ISOMIP_initialize_thickness - benchmark_initialize_thickness - Neverworld_initialize_thickness - circle_obcs_initialize_thickness - lock_exchange_initialize_thickness - external_gwave_initialize_thickness - DOME2d_initialize_thickness - adjustment_initialize_thickness - sloshing_initialize_thickness - seamount_initialize_thickness - dumbbell_initialize_thickness - soliton_initialize_thickness - Phillips_initialize_thickness - Rossby_front_initialize_thickness - user_initialize_thickness - DOME2d_initialize_temperature_salinity - ISOMIP_initialize_temperature_salinity - adjustment_initialize_temperature_salinity - baroclinic_zone_init_temperature_salinity - sloshing_initialize_temperature_salinity - seamount_initialize_temperature_salinity - dumbbell_initialize_temperature_salinity - Rossby_front_initialize_temperature_salinity - SCM_CVMix_tests_TS_init - dense_water_initialize_TS - adjustEtaToFitBathymetry Similar changes were made internally to MOM_temp_salt_initialize_from_Z to defer the transition to working in thickness units, although the appropriate call to convert_thickness does still occur within MOM_temp_salt_initialize_from_Z and the units of its arguments are not changed. The routine convert thickness was modified to work with a new input depth space input thickness argument and return a thickness in thickness units, and it is now being called after all of the routines to initialize thicknesses and temperatures and salinities, except in the few cases where the thickness are being specified directly in mass-based thickness units, as might happen when they are read from an input file. The new option "mass_file" is now a recognized option for the THICKNESS_CONFIG runtime parameter, and this information is passed in the new mass_file argument to initialize_thickness_from_file. The description of the runtime parameter THICKNESS_IC_RESCALE was updated to reflect this change. The unused thickness (h) argument to soliton_initialize_velocity was eliminated. The unused thickness (h) argument to determine_temperature was eliminated, as was the unused optional h_massless argument to the same function. This commit also rearranges the calls to do adjustments to the thicknesses to account for the presence of an ice shelf or to iteratively apply the ALE remapping to occur before the velocities are initialized, so that there is a clearer separation of the phases of the initialization. Also added optional height_units argument to ALE_initThicknessToCoord to specify that the coordinate are to be returned in height_units. If it is omitted or false, the previous thickness units are returned, but when called from MOM_initialize_state the new argument is being used. The runtime parameter CONVERT_THICKNESS_UNITS is no longer meaningful, so it has been obsoleted. All answers are bitwise identical, but there are multiple changes to the arguments to publicly visible subroutines or their units, and there are changes to the contents of the MOM_parameter_doc files. --- src/ALE/MOM_ALE.F90 | 12 +- src/diagnostics/MOM_obsolete_params.F90 | 1 + .../MOM_state_initialization.F90 | 304 ++++++++++-------- src/tracer/MOM_tracer_Z_init.F90 | 17 +- src/user/DOME2d_initialization.F90 | 36 +-- src/user/DOME_initialization.F90 | 6 +- src/user/ISOMIP_initialization.F90 | 26 +- src/user/Neverworld_initialization.F90 | 14 +- src/user/Phillips_initialization.F90 | 6 +- src/user/Rossby_front_2d_initialization.F90 | 14 +- src/user/SCM_CVMix_tests.F90 | 4 +- src/user/adjustment_initialization.F90 | 18 +- src/user/baroclinic_zone_initialization.F90 | 6 +- src/user/benchmark_initialization.F90 | 10 +- src/user/circle_obcs_initialization.F90 | 18 +- src/user/dense_water_initialization.F90 | 6 +- src/user/dumbbell_initialization.F90 | 18 +- src/user/external_gwave_initialization.F90 | 4 +- src/user/lock_exchange_initialization.F90 | 4 +- src/user/seamount_initialization.F90 | 18 +- src/user/sloshing_initialization.F90 | 6 +- src/user/soliton_initialization.F90 | 7 +- src/user/user_initialization.F90 | 7 +- 23 files changed, 295 insertions(+), 267 deletions(-) diff --git a/src/ALE/MOM_ALE.F90 b/src/ALE/MOM_ALE.F90 index e40bba3e2f..a341fd1835 100644 --- a/src/ALE/MOM_ALE.F90 +++ b/src/ALE/MOM_ALE.F90 @@ -1463,17 +1463,23 @@ subroutine ALE_writeCoordinateFile( CS, GV, directory ) end subroutine ALE_writeCoordinateFile !> Set h to coordinate values for fixed coordinate systems -subroutine ALE_initThicknessToCoord( CS, G, GV, h ) +subroutine ALE_initThicknessToCoord( CS, G, GV, h, height_units ) type(ALE_CS), intent(inout) :: CS !< module control structure type(ocean_grid_type), intent(in) :: G !< module grid structure type(verticalGrid_type), intent(in) :: GV !< Ocean vertical grid structure - real, dimension(SZI_(G),SZJ_(G),SZK_(GV)), intent(out) :: h !< layer thickness [H ~> m or kg m-2] + real, dimension(SZI_(G),SZJ_(G),SZK_(GV)), intent(out) :: h !< layer thickness in thickness units + !!

This new version also takes the tv%p_surf field into account and it has an optional halo_size argument, analogous to that in the other routines in the MOM_density_integrals module. The dz_to_thickness interface is overloaded so that it can also be used directly with temperature, salinity, and the equation of state type if the thermo_var_ptrs is not available. There is also a new and separate variant of this routine, dz_to_thickness_simple, that can be used in pure layered mode when temperature and salinity are not state variables, or (more dangerously) if it is not clear whether or not there is an equation of state. This simpler version is being kept separate from the main overloaded interface because its use may need to be revisited later in some cases. All answers are bitwise identical, but there are two new public interfaces, dz_to_thickness and dz_to_thickness_simple. --- src/core/MOM_interface_heights.F90 | 186 +++++++++++++++++- .../MOM_state_initialization.F90 | 89 +-------- 2 files changed, 190 insertions(+), 85 deletions(-) diff --git a/src/core/MOM_interface_heights.F90 b/src/core/MOM_interface_heights.F90 index af444de941..4f41cb074b 100644 --- a/src/core/MOM_interface_heights.F90 +++ b/src/core/MOM_interface_heights.F90 @@ -3,25 +3,31 @@ module MOM_interface_heights !

These include: - Refactored trim_for_ice to have a separate, simpler form appropriate for use in non-Boussinesq mode. The units of the min_thickness argument to cut_off_column top were also changed to thickness units. - Initialize_sponges_file was refactored to work in depth-space variables before using dz_to_thickness to convert to thicknesses, but also to properly handle the case where the input file has a different number of vertical layers than the model is using, in which case the previous version could have had a segmentation fault. - Code in MOM_temp_salt_initialize_from_Z was reordered to more clearly group it into distinct phases. It also uses the new dz_to_thickness routine to convert input depths into thicknesses. All answers are bitwise identical in all Boussinesq test cases and all test cases in the MOM6-examples regression suite, but answers could be changed and improved in some non-Boussinesq cases. --- .../MOM_state_initialization.F90 | 213 +++++++++++------- 1 file changed, 126 insertions(+), 87 deletions(-) diff --git a/src/initialization/MOM_state_initialization.F90 b/src/initialization/MOM_state_initialization.F90 index 09755ec354..0321d7511a 100644 --- a/src/initialization/MOM_state_initialization.F90 +++ b/src/initialization/MOM_state_initialization.F90 @@ -17,7 +17,7 @@ module MOM_state_initialization use MOM_file_parser, only : log_version use MOM_get_input, only : directories use MOM_grid, only : ocean_grid_type, isPointInCell -use MOM_interface_heights, only : find_eta, dz_to_thickness +use MOM_interface_heights, only : find_eta, dz_to_thickness, dz_to_thickness_simple use MOM_io, only : file_exists, field_size, MOM_read_data, MOM_read_vector, slasher use MOM_open_boundary, only : ocean_OBC_type, open_boundary_init, set_tracer_data use MOM_open_boundary, only : OBC_NONE @@ -1113,7 +1113,7 @@ subroutine trim_for_ice(PF, G, GV, US, ALE_CSp, tv, h, just_read) ! of temperature within each layer [C ~> degC] character(len=200) :: inputdir, filename, p_surf_file, p_surf_var !

For the user modules, the presence or absence of an equation of state is known and handled properly, but MOM_initialize_tracer_from_Z works with the generic tracer code and it it outside of the scope of MOM6 code to provide any information about the equation of state or the state variables that would be needed to initialize a non-Boussinesq model properly from a depth-space input file. For now we are doing the best we can, but this should be revisited. All examples in existing test cases are bitwise identical, but answers could change (and be improved) in any non-Boussinesq variants of the relevant test cases. --- .../MOM_tracer_initialization_from_Z.F90 | 14 ++++- src/user/DOME2d_initialization.F90 | 24 ++++--- src/user/ISOMIP_initialization.F90 | 63 ++++++++++--------- src/user/dense_water_initialization.F90 | 24 ++++--- src/user/dumbbell_initialization.F90 | 32 +++++++--- 5 files changed, 105 insertions(+), 52 deletions(-) diff --git a/src/initialization/MOM_tracer_initialization_from_Z.F90 b/src/initialization/MOM_tracer_initialization_from_Z.F90 index bd77ec54d5..64f6673371 100644 --- a/src/initialization/MOM_tracer_initialization_from_Z.F90 +++ b/src/initialization/MOM_tracer_initialization_from_Z.F90 @@ -12,6 +12,7 @@ module MOM_tracer_initialization_from_Z use MOM_file_parser, only : get_param, param_file_type, log_version use MOM_grid, only : ocean_grid_type use MOM_horizontal_regridding, only : myStats, horiz_interp_and_extrap_tracer +use MOM_interface_heights, only : dz_to_thickness_simple use MOM_remapping, only : remapping_CS, initialize_remapping use MOM_unit_scaling, only : unit_scale_type use MOM_verticalGrid, only : verticalGrid_type @@ -75,10 +76,12 @@ subroutine MOM_initialize_tracer_from_Z(h, tr, G, GV, US, PF, src_file, src_var_ real, allocatable, dimension(:), target :: z_in !

As with sigsetjmp, these functions are now disabled on default, and raise a runtime error if called by the program. Realistically, they will only be defined by an autoconf-configured build.

The autoconf compilation is now done entirely outside of the `ac/deps/fms/src` directory. This keeps the FMS checkout unchanged and allows us to better track any development changes in that library during development. The .testing/Makefile was also modified to use existing rules in deps/Makefile rather than duplicating them.

Previously, autoconf provided a flag to configure this with `--enable-*`, but was prone to two issues: * The binary choice of symmetric/nonsymmetric prevented use of static headers. * It was an incorrect use of `--enable-*`, which is intended to enable additional internal features; it is not used to select a mode. To address these issues, we drop the flag and replace it with an AC_ARG_VAR variable, MOM_MEMORY, which is a path to the file. This variable will default to dynamic symmetric mode, config_src/memory/dynamic_symmetric/MOM_memory.h so there should be no change for existing users. To the best of my knowledge, no one used the `--enable-*` flag, nor was it used in any automated systems (outside of .testing), so there should be no issue with dropping it. .testing/Makefile was updated to use MOM_MEMORY. --- .testing/Makefile | 5 +++-- ac/configure.ac | 40 ++++++++++++++++++++++++++++++---------- 2 files changed, 33 insertions(+), 12 deletions(-) diff --git a/.testing/Makefile b/.testing/Makefile index 237daadd96..a28bcc4bc4 100644 --- a/.testing/Makefile +++ b/.testing/Makefile @@ -246,7 +246,8 @@ COV_LDFLAGS := LDFLAGS="$(LDFLAGS_COVERAGE) $(LDFLAGS_DEPS) $(LDFLAGS_USER)" # Environment variable configuration build/symmetric/Makefile: MOM_ENV=$(PATH_FMS) $(SYMMETRIC_FCFLAGS) $(MOM_LDFLAGS) -build/asymmetric/Makefile: MOM_ENV=$(PATH_FMS) $(ASYMMETRIC_FCFLAGS) $(MOM_LDFLAGS) +build/asymmetric/Makefile: MOM_ENV=$(PATH_FMS) $(ASYMMETRIC_FCFLAGS) $(MOM_LDFLAGS) \ + MOM_MEMORY=../../../config_src/memory/dynamic_nonsymmetric/MOM_memory.h build/repro/Makefile: MOM_ENV=$(PATH_FMS) $(REPRO_FCFLAGS) $(MOM_LDFLAGS) build/openmp/Makefile: MOM_ENV=$(PATH_FMS) $(OPENMP_FCFLAGS) $(MOM_LDFLAGS) build/target/Makefile: MOM_ENV=$(PATH_FMS) $(TARGET_FCFLAGS) $(MOM_LDFLAGS) @@ -260,7 +261,7 @@ build/unit/Makefile: MOM_ENV=$(PATH_FMS) $(COV_FCFLAGS) $(COV_LDFLAGS) # Configure script flags build/symmetric/Makefile: MOM_ACFLAGS= -build/asymmetric/Makefile: MOM_ACFLAGS=--enable-asymmetric +build/asymmetric/Makefile: MOM_ACFLAGS= build/repro/Makefile: MOM_ACFLAGS= build/openmp/Makefile: MOM_ACFLAGS=--enable-openmp build/target/Makefile: MOM_ACFLAGS= diff --git a/ac/configure.ac b/ac/configure.ac index 9a634c1255..1c10c14495 100644 --- a/ac/configure.ac +++ b/ac/configure.ac @@ -39,14 +39,30 @@ AC_CONFIG_MACRO_DIR([m4]) srcdir=$srcdir/.. -# Default to symmetric grid -# NOTE: --enable is more properly used to add a feature, rather than to select -# a compile-time mode, so this is not exactly being used as intended. -MEM_LAYOUT=${srcdir}/config_src/memory/dynamic_symmetric -AC_ARG_ENABLE([asymmetric], - AS_HELP_STRING([--enable-asymmetric], [Use the asymmetric grid])) -AS_IF([test "$enable_asymmetric" = yes], - [MEM_LAYOUT=${srcdir}/config_src/memory/dynamic_nonsymmetric]) +# Configure the memory layout header + +AC_ARG_VAR([MOM_MEMORY], + [Path to MOM_memory.h header, describing the field memory layout: dynamic + symmetric (default), dynamic asymmetric, or static.] +) + +AS_VAR_IF([MOM_MEMORY], [], + [MOM_MEMORY=${srcdir}/config_src/memory/dynamic_symmetric/MOM_memory.h] +) + +# Confirm that MOM_MEMORY is named 'MOM_memory.h' +AS_IF([test $(basename "${MOM_MEMORY}") == "MOM_memory.h"], [], + [AC_MSG_ERROR([MOM_MEMORY header ${MOM_MEMORY} must be named 'MOM_memory.h'])] +) + +# Confirm that the file exists +AC_CHECK_FILE(["$MOM_MEMORY"], [], + [AC_MSG_ERROR([MOM_MEMORY header ${MOM_MEMORY} not found.])] +) + +MOM_MEMORY_DIR=$(AS_DIRNAME(["${MOM_MEMORY}"])) +AC_SUBST([MOM_MEMORY_DIR]) + # Default to solo_driver DRIVER_DIR=${srcdir}/config_src/drivers/solo_driver @@ -234,8 +250,12 @@ AC_SUBST([MAKEDEP]) # Generate source list and configure dependency command -AC_SUBST([SRC_DIRS], - ["${srcdir}/src ${MODEL_FRAMEWORK} ${srcdir}/config_src/external ${DRIVER_DIR} ${MEM_LAYOUT}"] +AC_SUBST([SRC_DIRS], ["\\ + ${srcdir}/src \\ + ${MODEL_FRAMEWORK} \\ + ${srcdir}/config_src/external \\ + ${DRIVER_DIR} \\ + ${MOM_MEMORY_DIR}"] ) AC_CONFIG_COMMANDS(Makefile.dep, [make depend]) From b32b2ed7ad33bc1d622f4421adc219eafb70d7bd Mon Sep 17 00:00:00 2001 From: Marshall Ward Date: Thu, 20 Apr 2023 22:01:17 -0400 Subject: [PATCH 0709/1329] Profiling: subparameter parser support The very crude MOM_input parser in the automatic profiler did not support subparameters (e.g. MLE% ... %MLE), which caused an error when trying to read the FMS clock output.

From e86b35adfd9bc3828aa9ae66d69d860e04358da7 Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Sat, 29 Apr 2023 11:04:47 -0400 Subject: [PATCH 0714/1329] +Add thickness_to_dz and calc_derived_thermo Added the new overloaded interface thickness_to_dz to convert the layer thicknesses in thickness units [H ~> m or kg m-2] into vertical distances in [Z ~> m], with variants that set full 3-d arrays or an i-/k- slice. Also added a field (SpV_avg) for the layer-averaged specific volume to the thermo_vars_ptr type and the new subroutine calc_derived_thermo to set it. This new subroutine is being called after halo updates to the temperatures and salinities. The new runtime parameter SEMI_BOUSSINESQ was added to determine whether tv%SpV_avg is allocated and used; it is stored in GV%semi_Boussinesq. Also added the new element GV%dZ_subroundoff to the verticalGrid_type as a counterpart to GV%H_subroundoff but in height units. All answers are bitwise identical, but there is a new runtime parameter in some MOM_parameter_doc files, new elements in a transparent type and a new public interface. --- src/core/MOM.F90 | 42 +++++- src/core/MOM_interface_heights.F90 | 124 +++++++++++++++++- src/core/MOM_variables.F90 | 3 + .../vertical/MOM_diabatic_driver.F90 | 10 +- src/tracer/MOM_offline_main.F90 | 8 ++ 5 files changed, 179 insertions(+), 8 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index c61ed72e0c..af8481fd1c 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -91,7 +91,7 @@ module MOM use MOM_grid, only : set_first_direction, rescale_grid_bathymetry use MOM_hor_index, only : hor_index_type, hor_index_init use MOM_hor_index, only : rotate_hor_index -use MOM_interface_heights, only : find_eta +use MOM_interface_heights, only : find_eta, calc_derived_thermo use MOM_interface_filter, only : interface_filter, interface_filter_init, interface_filter_end use MOM_interface_filter, only : interface_filter_CS use MOM_lateral_mixing_coeffs, only : calc_slope_functions, VarMix_init, VarMix_end @@ -1400,6 +1400,12 @@ subroutine step_MOM_tracer_dyn(CS, G, GV, US, h, Time_local) call create_group_pass(pass_T_S, CS%tv%T, G%Domain, To_All+Omit_Corners, halo=1) call create_group_pass(pass_T_S, CS%tv%S, G%Domain, To_All+Omit_Corners, halo=1) call do_group_pass(pass_T_S, G%Domain, clock=id_clock_pass) + halo_sz = 1 + endif + + !

This is a replacement for the MOM_wave_structure function, which could be removed in a subsequent PR. Additional arrays for mode strucures and integral quantities are passed as output hence this is a breaking change for the call to wave_speeds. However it is only called once in diabatic_driver and is used exclusively for internal tides ray tracing. The dimensional solutions for the wave structures are now computed inside MOM_internal_tides, and new diagnostics are added. An out-of-bounds bug is also corrected for the computation of an averaged coriolis parameter. --- src/diagnostics/MOM_wave_speed.F90 | 257 ++++++++++++++++-- .../lateral/MOM_internal_tides.F90 | 153 ++++++++++- .../vertical/MOM_diabatic_driver.F90 | 5 +- 3 files changed, 384 insertions(+), 31 deletions(-) diff --git a/src/diagnostics/MOM_wave_speed.F90 b/src/diagnostics/MOM_wave_speed.F90 index 9c8cd099f3..bb1b381c15 100644 --- a/src/diagnostics/MOM_wave_speed.F90 +++ b/src/diagnostics/MOM_wave_speed.F90 @@ -7,7 +7,7 @@ module MOM_wave_speed use MOM_error_handler, only : MOM_error, FATAL, WARNING use MOM_file_parser, only : log_version use MOM_grid, only : ocean_grid_type -use MOM_remapping, only : remapping_CS, initialize_remapping, remapping_core_h +use MOM_remapping, only : remapping_CS, initialize_remapping, remapping_core_h, interpolate_column use MOM_unit_scaling, only : unit_scale_type use MOM_variables, only : thermo_var_ptrs use MOM_verticalGrid, only : verticalGrid_type @@ -651,17 +651,33 @@ subroutine tdma6(n, a, c, lam, y) end subroutine tdma6 !> Calculates the wave speeds for the first few barolinic modes. -subroutine wave_speeds(h, tv, G, GV, US, nmodes, cn, CS, full_halos) - type(ocean_grid_type), intent(in) :: G !< Ocean grid structure - type(verticalGrid_type), intent(in) :: GV !< Vertical grid structure - type(unit_scale_type), intent(in) :: US !< A dimensional unit scaling type - real, dimension(SZI_(G),SZJ_(G),SZK_(GV)), intent(in) :: h !< Layer thickness [H ~> m or kg m-2] - type(thermo_var_ptrs), intent(in) :: tv !< Thermodynamic variables - integer, intent(in) :: nmodes !< Number of modes - real, dimension(G%isd:G%ied,G%jsd:G%jed,nmodes), intent(out) :: cn !< Waves speeds [L T-1 ~> m s-1] - type(wave_speed_CS), intent(in) :: CS !< Wave speed control struct - logical, optional, intent(in) :: full_halos !< If true, do the calculation - !! over the entire data domain. +subroutine wave_speeds(h, tv, G, GV, US, nmodes, cn, CS, w_struct, u_struct, u_struct_max, u_struct_bot, Nb, int_w2, & + int_U2, int_N2w2, full_halos) + type(ocean_grid_type), intent(in) :: G !< Ocean grid structure + type(verticalGrid_type), intent(in) :: GV !< Vertical grid structure + type(unit_scale_type), intent(in) :: US !< A dimensional unit scaling type + real, dimension(SZI_(G),SZJ_(G),SZK_(GV)), intent(in) :: h !< Layer thickness [H ~> m or kg m-2] + type(thermo_var_ptrs), intent(in) :: tv !< Thermodynamic variables + integer, intent(in) :: nmodes !< Number of modes + type(wave_speed_CS), intent(in) :: CS !< Wave speed control struct + real, dimension(SZI_(G),SZJ_(G),SZK_(GV)+1,nmodes),intent(out) :: w_struct !< Wave Vertical profile [nondim] + real, dimension(SZI_(G),SZJ_(G),SZK_(GV),nmodes),intent(out) :: u_struct !< Wave Horizontal profile [Z-1 ~> m-1] + real, dimension(SZI_(G),SZJ_(G),nmodes), intent(out) :: cn !< Waves speeds [L T-1 ~> m s-1] + real, dimension(SZI_(G),SZJ_(G),nmodes), intent(out) :: u_struct_max !< Maximum of wave horizontal profile + !!

(It does not, however, test of PYTHON is actually a Python interpreter, but we can deal with that at a later date.) --- ac/configure.ac | 16 +++++++++++----- 1 file changed, 11 insertions(+), 5 deletions(-) diff --git a/ac/configure.ac b/ac/configure.ac index 1c10c14495..7ea1870816 100644 --- a/ac/configure.ac +++ b/ac/configure.ac @@ -236,15 +236,21 @@ AC_COMPILE_IFELSE( ] ) +# Python interpreter test -# Verify that Python is available -AC_PATH_PROGS([PYTHON], [python python3 python2], [ - AC_MSG_ERROR([Could not find python.]) -]) AC_ARG_VAR([PYTHON], [Python interpreter command]) +AS_VAR_SET_IF([PYTHON], [ + AC_PATH_PROGS([PYTHON], ["$PYTHON"], [none]) +], [ + AC_PATH_PROGS([PYTHON], [python python3 python2], [none]) +]) +AS_VAR_IF([PYTHON], [none], [ + AC_MSG_ERROR([Python interpreter not found.]) +]) + -# Verify that makedep is available +# Makedep test AC_PATH_PROG([MAKEDEP], [makedep], [${srcdir}/ac/makedep]) AC_SUBST([MAKEDEP]) From cb4574b3f540bd9e6bdfced6e04a56c8cbd6c3bb Mon Sep 17 00:00:00 2001 From: Niki Zadeh Date: Wed, 29 Mar 2023 10:09:37 -0400 Subject: [PATCH 0719/1329] Fix PGI runtime issue with class(*) - Some tests such as global_ALE_z crash under PGI (ncrc4.pgi20 or ncrc5.pgi227) with FATAL from PE 27: unsupported attribute type: get_variable_attribute_0d: file:INPUT/tideamp.nc- variable:GRID_X_T attribute: axis - PGI in general has issues with class(*) construct and in this case cannot recognize the axis argument to be a string. - This mod helps PGI recognize that the argument is a string. --- config_src/infra/FMS2/MOM_io_infra.F90 | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/config_src/infra/FMS2/MOM_io_infra.F90 b/config_src/infra/FMS2/MOM_io_infra.F90 index 8802761774..2c3a5b8ad3 100644 --- a/config_src/infra/FMS2/MOM_io_infra.F90 +++ b/config_src/infra/FMS2/MOM_io_infra.F90 @@ -1524,9 +1524,9 @@ subroutine categorize_axes(fileObj, filename, ndims, dim_names, is_x, is_y, is_t if (variable_exists(fileobj, trim(dim_names(i)))) then cartesian = "" if (variable_att_exists(fileobj, trim(dim_names(i)), "cartesian_axis")) then - call get_variable_attribute(fileobj, trim(dim_names(i)), "cartesian_axis", cartesian) + call get_variable_attribute(fileobj, trim(dim_names(i)), "cartesian_axis", cartesian(1:1)) elseif (variable_att_exists(fileobj, trim(dim_names(i)), "axis")) then - call get_variable_attribute(fileobj, trim(dim_names(i)), "axis", cartesian) + call get_variable_attribute(fileobj, trim(dim_names(i)), "axis", cartesian(1:1)) endif cartesian = adjustl(cartesian) if ((index(cartesian, "X") == 1) .or.

This additional information is required in order to replicate the axis data from the field, which is no longer provided by FMS2. The abstraction of this type also allows us to either extend it or redefine it in other frameworks as needed in the future. This primarily affects the usage of the following functions: - init_external_field - time_interp_external - horiz_interp_and_extrap_tracer The following solvers are updated: - MOM_open_boundary - MOM_ice_shelf - MOM_oda_driver - MOM_MEKE - MOM_ALE_sponge - MOM_diabatic_aux Of these, OBC was the most significant. The integer handle (fid) was previously used to determine if each segment field was constant or (if negative) read from a file. After being replaced by the derived type, a new flag was added to make this determination. All of the coupled drivers have been modified, since they support time interpolation of T and S fields. - FMS - MCT - NUOPC The NUOPC driver also includes modifications to its CFC11 and CFC12 fields. Changes to the MOM CFC modules replaces an `id == -1`-like test, which is not used by the derived type. This check has been removed, and we now solely rely on the `present(cfc_handle)` test. While this could change behavior, there does not seem to be any scenario where init_external_field would return -1 but would be passed to the function. (But I may eat these words.) --- .../FMS_cap/MOM_surface_forcing_gfdl.F90 | 15 +++-- .../mct_cap/mom_surface_forcing_mct.F90 | 15 +++-- .../nuopc_cap/mom_surface_forcing_nuopc.F90 | 28 +++++---- config_src/infra/FMS1/MOM_interp_infra.F90 | 54 +++++++++++------- config_src/infra/FMS2/MOM_interp_infra.F90 | 57 +++++++++++-------- src/core/MOM_open_boundary.F90 | 31 +++++----- src/framework/MOM_horizontal_regridding.F90 | 11 ++-- src/framework/MOM_interpolate.F90 | 27 +++++---- src/ice_shelf/MOM_ice_shelf.F90 | 17 +++--- src/ocean_data_assim/MOM_oda_driver.F90 | 15 ++--- src/parameterizations/lateral/MOM_MEKE.F90 | 7 ++- .../vertical/MOM_ALE_sponge.F90 | 32 +++++------ .../vertical/MOM_diabatic_aux.F90 | 3 +- src/tracer/MOM_CFC_cap.F90 | 20 ++++--- 14 files changed, 187 insertions(+), 145 deletions(-) diff --git a/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 b/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 index 26ab6269ef..f70cd34012 100644 --- a/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 +++ b/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 @@ -27,6 +27,7 @@ module MOM_surface_forcing_gfdl use MOM_grid, only : ocean_grid_type use MOM_interpolate, only : init_external_field, time_interp_external use MOM_interpolate, only : time_interp_external_init +use MOM_interpolate, only : external_field use MOM_io, only : slasher, write_version_number, MOM_read_data use MOM_io, only : read_netCDF_data use MOM_io, only : stdout_if_root @@ -153,8 +154,10 @@ module MOM_surface_forcing_gfdl !! in inputdir/temp_restore_mask.nc and the field should !! be named 'mask' real, pointer, dimension(:,:) :: trestore_mask => NULL() !< Mask for SST restoring [nondim] - integer :: id_srestore = -1 !< An id number for time_interp_external. - integer :: id_trestore = -1 !< An id number for time_interp_external. + type(external_field) :: srestore_handle + !< Handle for time-interpolated salt restoration field + type(external_field) :: trestore_handle + !< Handle for time-interpolated temperature restoration field type(forcing_diags), public :: handles !< Diagnostics handles @@ -345,7 +348,7 @@ subroutine convert_IOB_to_fluxes(IOB, fluxes, index_bounds, Time, valid_time, G, !

References to FMS1 read into an `axistype`, but the contents are transferred to an `axis_info`. FMS2 directly populates the `axis_info` content. The `get_external_field_info` calls are modified to return `axis_info` rather than `axistype`. The redundant `get_axis_data` function is also removed from `MOM_interp_infra`, since `get_axis_info` provides an equivalent operation. Generally speaking, this is not an improvement of the codebase. The FMS1 layer does a redundant copy of data from `axistype` to `axis_info`. The FMS2 layer is significantly worse, and re-opens the file to read the axis data for each field! But if the intention is to leverage the existing API, then I don't think we have any choice at the moment. Assuming this is a relatively infrequent operation, this should not cause any measureable issues, but it needs to be watched carefully. --- config_src/infra/FMS1/MOM_interp_infra.F90 | 44 +++++++++++++++------ config_src/infra/FMS2/MOM_interp_infra.F90 | 32 ++++++--------- src/framework/MOM_horizontal_regridding.F90 | 10 ++--- 3 files changed, 49 insertions(+), 37 deletions(-) diff --git a/config_src/infra/FMS1/MOM_interp_infra.F90 b/config_src/infra/FMS1/MOM_interp_infra.F90 index e14233a64b..70bc99827e 100644 --- a/config_src/infra/FMS1/MOM_interp_infra.F90 +++ b/config_src/infra/FMS1/MOM_interp_infra.F90 @@ -4,9 +4,11 @@ module MOM_interp_infra !

This is problematic for legacy or externally created input files which may have not identifed their time axis as unlimited. This patch adds a new function, `find_unlimited_dimension_name` which mirrors the FMS2 function but returns an empty string if none are found.

This includes moving the internal wave speed diagnostics and the call to wave_speeds or other code setting the internal wave speeds into propagate_int_tide. The get_param calls for INTERNAL_WAVE_CG1_THRESH and UNIFORM_TEST_CG were moved from the diabatic module to the MOM_internal_tides module. The wave_speed_CS and uniform_test_cg were removed from diabatic_CS and added to int_tide_CS. The Nb argument to propagate_int_tide has been made intent inout, as it is now usually set via the call to wave_speeds in that routine, but for certain tests it could use the value passed in from diabatic_driver. All answers are bitwise identical, but there are changes to public interfaces and types, and the order of some entries in the MOM_parameter_doc files and the available_diags files is changed for some cases. --- .../lateral/MOM_internal_tides.F90 | 65 ++++++++++++++++--- .../vertical/MOM_diabatic_driver.F90 | 57 +--------------- 2 files changed, 60 insertions(+), 62 deletions(-) diff --git a/src/parameterizations/lateral/MOM_internal_tides.F90 b/src/parameterizations/lateral/MOM_internal_tides.F90 index ec07939ee4..8c56107a4f 100644 --- a/src/parameterizations/lateral/MOM_internal_tides.F90 +++ b/src/parameterizations/lateral/MOM_internal_tides.F90 @@ -23,6 +23,7 @@ module MOM_internal_tides use MOM_unit_scaling, only : unit_scale_type use MOM_variables, only : surface, thermo_var_ptrs use MOM_verticalGrid, only : verticalGrid_type +use MOM_wave_speed, only : wave_speeds, wave_speed_CS, wave_speed_init implicit none ; private @@ -33,12 +34,14 @@ module MOM_internal_tides public get_lowmode_loss !> This control structure has parameters for the MOM_internal_tides module -type, public :: int_tide_CS +type, public :: int_tide_CS ; private logical :: do_int_tides !< If true, use the internal tide code. integer :: nFreq = 0 !< The number of internal tide frequency bands integer :: nMode = 1 !< The number of internal tide vertical modes integer :: nAngle = 24 !< The number of internal tide angular orientations integer :: energized_angle = -1 !< If positive, only this angular band is energized for debugging purposes + real :: uniform_test_cg !< Uniform group velocity of internal tide + !! for testing internal tides [L T-1 ~> m s-1] logical :: corner_adv !< If true, use a corner advection rather than PPM. logical :: upwind_1st !< If true, use a first-order upwind scheme. logical :: simple_2nd !< If true, use a simple second order (arithmetic mean) interpolation @@ -137,11 +140,14 @@ module MOM_internal_tides !< The internal wave energy density as a function of (i,j,angle); temporary for restart real, allocatable, dimension(:) :: frequency !< The frequency of each band [T-1 ~> s-1]. + type(wave_speed_CS) :: wave_speed !< Wave speed control structure type(diag_ctrl), pointer :: diag => NULL() !< A structure that is used to regulate the !! timing of diagnostic output. !>@{ Diag handles !

There is also a new tau_mag diagnostic. This same information in tau_mag is being transformed into ustar, but these changes avoid division by the Boussinesq reference density (GV%Rho0), and allow for a more accurate calculation of derived fields when in non-Boussinesq mode, without having to multiply and divide by GV%Rho0. There is also a new optional tau_mag argument to extract_IOB_stresses to support these changes. These new arrays are not being used yet in the MOM6 solutions, but they are being allocated and populated in the routines that set the ustar fields, and they have been tested in changes to the modules that use ustar that will come in a subsequent commit. This commit also adds the new RLZ_T2_to_Pa element to the unit_scale_type to undo the scaling of wind stresses and it makes use of it in some of the new code. All answers are bitwise identical, but there are new arrays or elements in three transparent public types. --- .../FMS_cap/MOM_surface_forcing_gfdl.F90 | 44 ++++++++---- .../mct_cap/mom_surface_forcing_mct.F90 | 4 ++ .../nuopc_cap/mom_surface_forcing_nuopc.F90 | 4 ++ .../solo_driver/MOM_surface_forcing.F90 | 61 +++++++++++----- .../solo_driver/user_surface_forcing.F90 | 5 +- src/core/MOM.F90 | 2 + src/core/MOM_forcing_type.F90 | 70 +++++++++++++++---- src/framework/MOM_unit_scaling.F90 | 2 + 8 files changed, 144 insertions(+), 48 deletions(-) diff --git a/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 b/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 index f70cd34012..251f37290d 100644 --- a/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 +++ b/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 @@ -624,13 +624,16 @@ subroutine convert_IOB_to_fluxes(IOB, fluxes, index_bounds, Time, valid_time, G, endif !

This does not appear to change any answers in the existing test cases, perhaps because the mixed layer restratification "tail" is not being activated by setting TAIL_DH to be larger than 0. - Corrected or added variable units in comments in the mixedlayer_restrat control structure. These could change answers (and avoid NaNs) in some cases with USE_BODNER23=True, MLE_TAIL_DH > 0 or MLE%TAIL_DH > 0, and there will be changes to the MOM_parameter_doc files for some cases, but given how recently this code was added, it is expected that all answers are bitwise identical in the existing test cases. --- .../lateral/MOM_mixed_layer_restrat.F90 | 79 ++++++++++--------- 1 file changed, 43 insertions(+), 36 deletions(-) diff --git a/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 b/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 index 12f494fc8a..206773ecb0 100644 --- a/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 +++ b/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 @@ -62,24 +62,25 @@ module MOM_mixed_layer_restrat !

There are new arguments to several publicly visible routines, including: - Add non_depth_H arguments to hybgen_regrid, build_zstar_grid, build_sigma_grid, build_rho_grid, build_grid_HyCOM1, build_grid_adaptive, build_adapt_column and build_grid_arbitrary - Add optional zScale arguments to build_zstar_grid and build_grid_HyCOM1 - Add unit_scale_type arguments to regridding_main, ALE_regrid_accelerated and ALE_offline_inputs Also eliminated an incorrect rescaling GV%Z_to_H facto when calculating the total column thickness from the layer thicknesses when an ice shelf is used with a Hycom grid. This would have caused dimensional consistency testing to fail. Added the new runtime parameters HYBGEN_H_THIN, HYBGEN_FAR_FROM_SURFACE HYBGEN_FAR_FROM_BOTTOM, and HYBGEN_DENSITY_EPSILON to set previously hard-coded dimensional parameters used in the Hybgen regridding code and store these values in new variables in hybgen_regrid_CS. Two of these are no longer passed to hybgen_column_regrid as separate parameters. By default these new runtime parameters recover the previous hard-coded values. Also eliminated an unused block of code in build_rho_column. Several comments documenting variables or their units were also added. All answers are bitwise identical, but there are 4 new runtime parameters that would appear in some MOM_parameter_doc files and there are changes to the arguments to 11 routines. --- src/ALE/MOM_ALE.F90 | 12 +- src/ALE/MOM_hybgen_regrid.F90 | 102 +++++--- src/ALE/MOM_regridding.F90 | 231 ++++++++++++------ src/ALE/coord_adapt.F90 | 14 +- src/ALE/coord_hycom.F90 | 4 +- src/ALE/coord_rho.F90 | 16 +- .../MOM_state_initialization.F90 | 4 +- src/tracer/MOM_offline_main.F90 | 2 +- 8 files changed, 241 insertions(+), 144 deletions(-) diff --git a/src/ALE/MOM_ALE.F90 b/src/ALE/MOM_ALE.F90 index a341fd1835..61ab6c93cf 100644 --- a/src/ALE/MOM_ALE.F90 +++ b/src/ALE/MOM_ALE.F90 @@ -483,7 +483,7 @@ subroutine ALE_regrid( G, GV, US, h, h_new, dzRegrid, tv, CS, frac_shelf_h, PCM_ !

These files will be written at the same time as other restart files. I cannot add these calls directly to the driver, because the driver does not have information about the particle location. We have added save_MOM6_internal_state as a subroutine in MOM.F90, and we added calls to this subroutine from each of the drivers. We hope this will allow for more new packages to write restart files in the future.

Tv%valid_SpV_halo is set to the halo size in calc_derived_thermo or after a halo update is done to tv%SpV_avg, and it is set to a negative value right after calls that change temperatures and salinities (such as by ALE remapping) unless there is a call to calc_derived_thermo. Tests for the validity of tv%SpV_avg are added to the routines behind thickness_to_dz, with fatal errors issued if invalid arrays would be used, but more tests could perhaps be used in any parameterization routines where tv%SpV_avg is used directly. Handling the updates to tv%SpV_avg this way helps to avoid unnecessary calls to calc_derived_thermo, which in turn has equation of state calls that can be expensive, while also providing essential verification of new code related to the non-Boussinesq code. These tests can probably be commented out or removed for efficiency once there is a full suite of regression tests for the fully non-Boussinesq mode of MOM6. In addition, a new optional debug argument was added to calc_derived_thermo which can be used to triggers checksums for the variables used to calculate tv%SpV_avg. One call to calc_derived_thermo was also added just before the initialization call to ALE_regrid that will be needed with the next commit, but does not change answers yet. All answers are bitwise identical, but there is a new element in a transparent and widely used type and a new optional argument to a public interface. --- src/ALE/MOM_ALE.F90 | 6 ++++ src/core/MOM.F90 | 24 ++++++++++---- src/core/MOM_interface_heights.F90 | 51 +++++++++++++++++++++++++----- src/core/MOM_variables.F90 | 2 ++ src/tracer/MOM_offline_main.F90 | 1 + 5 files changed, 70 insertions(+), 14 deletions(-) diff --git a/src/ALE/MOM_ALE.F90 b/src/ALE/MOM_ALE.F90 index 61ab6c93cf..4641747115 100644 --- a/src/ALE/MOM_ALE.F90 +++ b/src/ALE/MOM_ALE.F90 @@ -532,6 +532,7 @@ subroutine ALE_offline_inputs(CS, G, GV, US, h, tv, Reg, uhtr, vhtr, Kd, debug, !

The impacted interfaces are MEKE_int, vertvisc_coef, sumSWoverBands, KPP_calculate, differential_diffuse_T_S, set_BBL_TKE, and apply_sponge In the three step_MOM_dyn_... routines and in calculateBuoyancyFlux1d, this change includes calls to thickness_to_dz to calculate the new vertical distance arrays that will be passed into vertvisc_coef or sumSWoverBands. The only place where the new arguments are actually used is in sumSWoverBands and set_opacity where the changes are particularly simple. All answers are bitwise identical, but there are new non-optional arguments to seven publicly visible routines. --- src/core/MOM.F90 | 2 +- src/core/MOM_dynamics_split_RK2.F90 | 12 ++++++---- src/core/MOM_dynamics_unsplit.F90 | 12 ++++++---- src/core/MOM_dynamics_unsplit_RK2.F90 | 10 ++++++--- src/core/MOM_forcing_type.F90 | 5 ++++- src/parameterizations/lateral/MOM_MEKE.F90 | 7 +++--- .../vertical/MOM_CVMix_KPP.F90 | 3 ++- .../vertical/MOM_diabatic_aux.F90 | 10 ++++++--- .../vertical/MOM_diabatic_driver.F90 | 22 +++++++++---------- .../vertical/MOM_opacity.F90 | 10 +++++---- .../vertical/MOM_set_diffusivity.F90 | 3 ++- src/parameterizations/vertical/MOM_sponge.F90 | 17 ++++++++------ .../vertical/MOM_vert_friction.F90 | 6 ++++- 13 files changed, 75 insertions(+), 44 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 703514fc52..df3a308e85 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -3002,7 +3002,7 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, restart_CSp, & call cpu_clock_end(id_clock_MOM_init) if (CS%use_dbclient) call database_comms_init(param_file, CS%dbcomms_CS) - CS%useMEKE = MEKE_init(Time, G, US, param_file, diag, CS%dbcomms_CS, CS%MEKE_CSp, CS%MEKE, & + CS%useMEKE = MEKE_init(Time, G, GV, US, param_file, diag, CS%dbcomms_CS, CS%MEKE_CSp, CS%MEKE, & restart_CSp, CS%MEKE_in_dynamics) call VarMix_init(Time, G, GV, US, param_file, diag, CS%VarMix) diff --git a/src/core/MOM_dynamics_split_RK2.F90 b/src/core/MOM_dynamics_split_RK2.F90 index 9fb1a6b356..5ce9ec8962 100644 --- a/src/core/MOM_dynamics_split_RK2.F90 +++ b/src/core/MOM_dynamics_split_RK2.F90 @@ -50,7 +50,7 @@ module MOM_dynamics_split_RK2 use MOM_hor_index, only : hor_index_type use MOM_hor_visc, only : horizontal_viscosity, hor_visc_CS use MOM_hor_visc, only : hor_visc_init, hor_visc_end -use MOM_interface_heights, only : find_eta +use MOM_interface_heights, only : find_eta, thickness_to_dz use MOM_lateral_mixing_coeffs, only : VarMix_CS use MOM_MEKE_types, only : MEKE_type use MOM_open_boundary, only : ocean_OBC_type, radiation_open_bdry_conds @@ -322,6 +322,7 @@ subroutine step_MOM_dyn_split_RK2(u, v, h, tv, visc, Time_local, dt, forces, p_s real, dimension(SZIB_(G),SZJ_(G),SZK_(GV)) :: up !

This had the side affect that we get warnings about not using KVML even if KVML was not present. - The fix checks for KVML first, and then changes the default so that when KVML=1e-4 is replaced by KV_ML_INVZ2=1e-4 we end up with no warnings and KVML can be obsoleted safely. Note: this commit alone does not remove all warnings from the MOM6-examples suite because we still need to fix the MOM_input that still use KVML - KVML needs to be unscaled since it is the default for KV_ML_INVZ2 - tc3 used KVML and has been corrected. --- .testing/tc3/MOM_input | 8 +++--- .../vertical/MOM_vert_friction.F90 | 25 +++++++------------ 2 files changed, 13 insertions(+), 20 deletions(-) diff --git a/.testing/tc3/MOM_input b/.testing/tc3/MOM_input index a034960d1e..6963feee98 100644 --- a/.testing/tc3/MOM_input +++ b/.testing/tc3/MOM_input @@ -283,10 +283,10 @@ HMIX_FIXED = 20.0 !

This form follows the suggestions of Appendix A.3.2 of Griffies and Greatbatch (Ocean Modelling, 2012) when in non-Boussinesq mode. Thickness_diffuse_full was also revised to work properly in non-Boussinesq mode (and not depend on the Boussinesq reference density) when no equation of state is used. As a part of these changes, the code now uses thickness-based streamfunctions and other thickness-based internal calculations in MOM_thickness_diffuse. For example, the overturning streamfunctions with this change are now in m3/s in Boussinesq mode, but kg/s in non-Boussinesq mode. These changes use a call to thickness_to_dz to set up a separate variable with the vertical distance across layers, and in non-Boussinesq mode they use tv%SpV_avg to estimate in situ densities. Additional debugging checksums were added to thickness_diffuse. The code changes are extensive with 15 new or renamed internal variables, and changes to the units of 9 other internal variables and 3 arguments to the private routine streamfn_solver. After this change, GV%Rho, GV%Z_to_H and GV%H_to_Z are no longer used in any non-Boussinesq calculations (12 such instances having been elimated). Because some calculations have to be redone with the separate thickness and dz variables, this will be more expensive than the original version. No public interfaces are changed, and all answers are bitwise identical in Boussinesq or semiBoussinesq mode, but they will change in non-Boussinesq mode when the isopycnal height diffusion parameterization is used. --- .../lateral/MOM_thickness_diffuse.F90 | 286 ++++++++++++------ 1 file changed, 195 insertions(+), 91 deletions(-) diff --git a/src/parameterizations/lateral/MOM_thickness_diffuse.F90 b/src/parameterizations/lateral/MOM_thickness_diffuse.F90 index a7ff2f1c0a..8617795e16 100644 --- a/src/parameterizations/lateral/MOM_thickness_diffuse.F90 +++ b/src/parameterizations/lateral/MOM_thickness_diffuse.F90 @@ -14,7 +14,7 @@ module MOM_thickness_diffuse use MOM_file_parser, only : get_param, log_version, param_file_type use MOM_grid, only : ocean_grid_type use MOM_io, only : MOM_read_data, slasher -use MOM_interface_heights, only : find_eta +use MOM_interface_heights, only : find_eta, thickness_to_dz use MOM_isopycnal_slopes, only : vert_fill_TS use MOM_lateral_mixing_coeffs, only : VarMix_CS use MOM_MEKE_types, only : MEKE_type @@ -439,7 +439,6 @@ subroutine thickness_diffuse(h, uhtr, vhtr, tv, dt, G, GV, US, MEKE, VarMix, CDp endif endif - !$OMP do do K=1,nz+1 ; do j=js,je ; do I=is-1,ie ; int_slope_u(I,j,K) = 0.0 ; enddo ; enddo ; enddo !$OMP do @@ -458,6 +457,12 @@ subroutine thickness_diffuse(h, uhtr, vhtr, tv, dt, G, GV, US, MEKE, VarMix, CDp if (CS%debug) then call uvchksum("Kh_[uv]", Kh_u, Kh_v, G%HI, haloshift=0, & scale=(US%L_to_m**2)*US%s_to_T, scalar_pair=.true.) + call uvchksum("Kh_[uv]_CFL", Kh_u_CFL, Kh_v_CFL, G%HI, haloshift=0, & + scale=(US%L_to_m**2)*US%s_to_T, scalar_pair=.true.) + if (Resoln_scaled) then + call uvchksum("Res_fn_[uv]", VarMix%Res_fn_u, VarMix%Res_fn_v, G%HI, haloshift=0, & + scale=1.0, scalar_pair=.true.) + endif call uvchksum("int_slope_[uv]", int_slope_u, int_slope_v, G%HI, haloshift=0) call hchksum(h, "thickness_diffuse_1 h", G%HI, haloshift=1, scale=GV%H_to_m) call hchksum(e, "thickness_diffuse_1 e", G%HI, haloshift=1, scale=US%Z_to_m) @@ -628,14 +633,17 @@ subroutine thickness_diffuse_full(h, e, Kh_u, Kh_v, tv, uhD, vhD, cg1, dt, G, GV ! by dt [H L2 T-1 ~> m3 s-1 or kg s-1]. h_frac !

Tweaking the brine plume code. * Using the proper MLD in the brine plumes - it now works better on restart * Always including MLD in call to applyBoundary... - I could move it up and make it not optional. * Adding some OpenMP directives to brine plumes --- .../FMS_cap/MOM_surface_forcing_gfdl.F90 | 13 ++- docs/zotero.bib | 9 ++ src/core/MOM_continuity_PPM.F90 | 8 +- src/core/MOM_forcing_type.F90 | 16 ++-- .../vertical/MOM_diabatic_aux.F90 | 82 +++++++++++++++++-- .../vertical/MOM_diabatic_driver.F90 | 8 +- .../vertical/MOM_set_viscosity.F90 | 34 ++++---- 7 files changed, 132 insertions(+), 38 deletions(-) diff --git a/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 b/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 index 251f37290d..a8398c3cc8 100644 --- a/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 +++ b/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 @@ -62,7 +62,7 @@ module MOM_surface_forcing_gfdl !! from MOM_domains) to indicate the staggering of !! the winds that are being provided in calls to !! update_ocean_model. - logical :: use_temperature !< If true, temp and saln used as state variables + logical :: use_temperature !< If true, temp and saln used as state variables. real :: wind_stress_multiplier !< A multiplier applied to incoming wind stress [nondim]. real :: Rho0 !< Boussinesq reference density [R ~> kg m-3] @@ -175,6 +175,7 @@ module MOM_surface_forcing_gfdl real, pointer, dimension(:,:) :: t_flux =>NULL() !< sensible heat flux [W m-2] real, pointer, dimension(:,:) :: q_flux =>NULL() !< specific humidity flux [kg m-2 s-1] real, pointer, dimension(:,:) :: salt_flux =>NULL() !< salt flux [kg m-2 s-1] + real, pointer, dimension(:,:) :: excess_salt =>NULL() !< salt left behind by brine rejection [kg m-2 s-1] real, pointer, dimension(:,:) :: lw_flux =>NULL() !< long wave radiation [W m-2] real, pointer, dimension(:,:) :: sw_flux_vis_dir =>NULL() !< direct visible sw radiation [W m-2] real, pointer, dimension(:,:) :: sw_flux_vis_dif =>NULL() !< diffuse visible sw radiation [W m-2] @@ -304,6 +305,8 @@ subroutine convert_IOB_to_fluxes(IOB, fluxes, index_bounds, Time, valid_time, G, call safe_alloc_ptr(fluxes%heat_added,isd,ied,jsd,jed) call safe_alloc_ptr(fluxes%salt_flux_added,isd,ied,jsd,jed) + if (associated(IOB%excess_salt)) call safe_alloc_ptr(fluxes%salt_left_behind,isd,ied,jsd,jed) + do j=js-2,je+2 ; do i=is-2,ie+2 fluxes%TKE_tidal(i,j) = CS%TKE_tidal(i,j) fluxes%ustar_tidal(i,j) = CS%ustar_tidal(i,j) @@ -576,6 +579,11 @@ subroutine convert_IOB_to_fluxes(IOB, fluxes, index_bounds, Time, valid_time, G, call check_mask_val_consistency(IOB%salt_flux(i-i0,j-j0), G%mask2dT(i,j), i, j, 'salt_flux', G) enddo ; enddo endif + if (associated(IOB%excess_salt)) then + do j=js,je ; do i=is,ie + fluxes%salt_left_behind(i,j) = G%mask2dT(i,j)*(kg_m2_s_conversion*IOB%excess_salt(i-i0,j-j0)) + enddo ; enddo + endif !#CTRL# if (associated(CS%ctrl_forcing_CSp)) then !#CTRL# do j=js,je ; do i=is,ie @@ -1729,6 +1737,9 @@ subroutine ice_ocn_bnd_type_chksum(id, timestep, iobt) if (associated(iobt%mass_berg)) then chks = field_chksum( iobt%mass_berg ) ; if (root) write(outunit,100) 'iobt%mass_berg ', chks endif + if (associated(iobt%excess_salt)) then + chks = field_chksum( iobt%excess_salt ) ; if (root) write(outunit,100) 'iobt%excess_salt ', chks + endif 100 FORMAT(" CHECKSUM::",A20," = ",Z20) call coupler_type_write_chksums(iobt%fluxes, outunit, 'iobt%') diff --git a/docs/zotero.bib b/docs/zotero.bib index c0c7ee3bd9..5acaee968a 100644 --- a/docs/zotero.bib +++ b/docs/zotero.bib @@ -2738,3 +2738,12 @@ @article{kraus1967 journal = {Tellus} } +@article{Nguyen2009, + doi = {10.1029/2008JC005121}, + year = {2009}, + journal = {JGR Oceans}, + volume = {114}, + author = {A.

The units of 4 vertical diffusivities in the control structures in 4 different modules are also changed accordingly.

Find_ustar is an overloaded interface to find_ustar_fluxes or find_ustar_mech_forcing, which are the same but for the type of one of their arguments. For now, the subroutines bulkmixedlayer, mixedlayer_restrajt_OM4, mixedlayer_restrat_Bodner and mixedlayer_restrat_BML are calling find_ustar to avoid code duplication during the transition to work in fully non-Boussinesq mode, but it will eventually be used in about another half dozen other places. All Boussinesq answers are bitwise identical, but non-Boussinesq answers will change and become less dependent on the Boussinesq reference density, and there is a new publicly visible interface wrapping two subroutines. --- src/core/MOM_forcing_type.F90 | 141 +++++++++++++++++- .../lateral/MOM_mixed_layer_restrat.F90 | 36 +++-- .../vertical/MOM_bulk_mixed_layer.F90 | 19 ++- 3 files changed, 182 insertions(+), 14 deletions(-) diff --git a/src/core/MOM_forcing_type.F90 b/src/core/MOM_forcing_type.F90 index 9623256b88..a6d35903ee 100644 --- a/src/core/MOM_forcing_type.F90 +++ b/src/core/MOM_forcing_type.F90 @@ -29,7 +29,7 @@ module MOM_forcing_type public extractFluxes1d, extractFluxes2d, optics_type public MOM_forcing_chksum, MOM_mech_forcing_chksum -public calculateBuoyancyFlux1d, calculateBuoyancyFlux2d +public calculateBuoyancyFlux1d, calculateBuoyancyFlux2d, find_ustar public forcing_accumulate, fluxes_accumulate public forcing_SinglePointPrint, mech_forcing_diags, forcing_diagnostics public register_forcing_type_diags, allocate_forcing_type, deallocate_forcing_type @@ -53,6 +53,12 @@ module MOM_forcing_type module procedure allocate_mech_forcing_from_ref end interface allocate_mech_forcing +!> Determine the friction velocity from a forcing type or a mechanical forcing type. +interface find_ustar + module procedure find_ustar_fluxes + module procedure find_ustar_mech_forcing +end interface find_ustar + !

Accordingly, the units of one element each in the diagnostics_CS and wave_speed_CS and a local variable in VarMix_init are also changed to thickness units. The unit descriptions of some comments describing diagnostics were also amended to also describe the non-Boussinesq versions.

The default is set to RHO_0 and answers do not change by default. This new parameter is used in non-Boussinesq mode with some options in btcalc and find_face_areas, when LINEARIZED_BT_CORIOLIS = True or BT_NONLIN_STRESS = False, and in the unit conversion of the ice strength with dynamic pressure. Also cancelled out factors of GV%Z_to_H in MOM_barotropic.F90 to simplify the code and reduce the dependence on the value of GV%Rho_0 in non-Boussinesq mode. This involved changing the units of 4 variables in the barotropic_CS type, 3 internal variables in btstep and an internal variable in barotropic_init to use thickness units. The rescaled internal variable mass_to_Z was also replaced with the equivalent GV%RZ_to_H. There are also 4 new debugging messages. Also modified the units of the gtot_est argument to match those of pbce. There is a new element in barotropic_CS. Because GV%Z_to_H is an exact power of 2 in Boussinesq mode, all answers are bitwise identical in that mode, but in non-Boussinesq mode this conversion involves multiplication and division by GV%Rho_0, so while all answers are mathematically equivalent, this change does change answers at roundoff in non-Boussinesq mode. Additionally there is a new runtime parameter that will appear in some MOM_parameter_doc files. --- src/core/MOM_barotropic.F90 | 193 ++++++++++++++++++++++-------------- 1 file changed, 118 insertions(+), 75 deletions(-) diff --git a/src/core/MOM_barotropic.F90 b/src/core/MOM_barotropic.F90 index 40f759f4b8..adbbd3b4dd 100644 --- a/src/core/MOM_barotropic.F90 +++ b/src/core/MOM_barotropic.F90 @@ -3,8 +3,9 @@ module MOM_barotropic !

This change includes the addition of a thermo_var_ptrs argument to 5 routines (initialize_DOME_tracer, initialize_dye_tracer, dye_tracer_column_physics ideal_age_tracer_column_physics and count_BL_layers) and changes to the units of some internal variables, and the addition of 6 new 2-d or 3-d arrays with the vertical distance across layers. An unused param_file_type argument to initialize_DOME_tracer was also eliminated. Comments were also added to describe the units of 5 of the variables in the ideal age tracer control structure and 7 internal variables in that same module, and there was some minor cleanup of the formatting cf calls in tracer_flow_control_init. There was some minor refactoring in the ns2_tracers module to use SZK_(GV) instead of SZK_(G) to declare the vertical extent of some arrays, and the vertical indexing convention for interfaces in nw2_tracer_dist was revised from starting at 0 to start at 1 for consistency with all the other code in MOM6. Also moved the code to do halo updates for the physical model state variables and call calc_derived_thermo before calling tracer_flow_control_init, because some routines there are now using the layer average specific volume to convert between thicknesses and heights when in non-Boussinesq mode. All answers in Boussinesq mode are bitwise identical, but these passive tracer modules have slightly different answers in non-Boussinesq mode. There are changes to the non-optional arguments to 4 public interfaces. --- src/core/MOM.F90 | 40 ++++++++-------- src/tracer/DOME_tracer.F90 | 66 ++++++++++++++------------ src/tracer/MOM_tracer_flow_control.F90 | 27 +++++------ src/tracer/dye_example.F90 | 39 ++++++++------- src/tracer/ideal_age_example.F90 | 66 ++++++++++++++------------ src/tracer/nw2_tracers.F90 | 39 ++++++++------- 6 files changed, 149 insertions(+), 128 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index d7e2d74735..d1d4be51dd 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -3124,26 +3124,6 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, restart_CSp, & call ALE_register_diags(Time, G, GV, US, diag, CS%ALE_CSp) endif - !

Also removes the `restart_CSp` argument from `MOM_wave_interface_init`, since it appeared to be used for nothing. --- .../drivers/FMS_cap/ocean_model_MOM.F90 | 26 +++---- .../drivers/mct_cap/mom_ocean_model_mct.F90 | 28 +++---- .../nuopc_cap/mom_ocean_model_nuopc.F90 | 36 ++++----- config_src/drivers/solo_driver/MOM_driver.F90 | 25 +++---- src/core/MOM.F90 | 74 ++++++++++--------- src/user/MOM_wave_interface.F90 | 3 +- 6 files changed, 84 insertions(+), 108 deletions(-) diff --git a/config_src/drivers/FMS_cap/ocean_model_MOM.F90 b/config_src/drivers/FMS_cap/ocean_model_MOM.F90 index bd86a633c6..5fde791724 100644 --- a/config_src/drivers/FMS_cap/ocean_model_MOM.F90 +++ b/config_src/drivers/FMS_cap/ocean_model_MOM.F90 @@ -14,7 +14,8 @@ module ocean_model_mod use MOM, only : initialize_MOM, step_MOM, MOM_control_struct, MOM_end use MOM, only : extract_surface_state, allocate_surface_state, finish_MOM_initialization use MOM, only : get_MOM_state_elements, MOM_state_is_synchronized -use MOM, only : get_ocean_stocks, step_offline, save_MOM6_internal_state +use MOM, only : get_ocean_stocks, step_offline +use MOM, only : save_MOM_restart use MOM_coms, only : field_chksum use MOM_constants, only : CELSIUS_KELVIN_OFFSET, hlf use MOM_coupler_types, only : coupler_1d_bc_type, coupler_2d_bc_type @@ -37,7 +38,6 @@ module ocean_model_mod use MOM_grid, only : ocean_grid_type use MOM_io, only : write_version_number, stdout_if_root use MOM_marine_ice, only : iceberg_forces, iceberg_fluxes, marine_ice_init, marine_ice_CS -use MOM_restart, only : MOM_restart_CS, save_restart use MOM_string_functions, only : uppercase use MOM_surface_forcing_gfdl, only : surface_forcing_init, convert_IOB_to_fluxes use MOM_surface_forcing_gfdl, only : convert_IOB_to_forces, ice_ocn_bnd_type_chksum @@ -209,9 +209,6 @@ module ocean_model_mod Waves => NULL() !< A pointer to the surface wave control structure type(surface_forcing_CS), pointer :: & forcing_CSp => NULL() !< A pointer to the MOM forcing control structure - type(MOM_restart_CS), pointer :: & - restart_CSp => NULL() !< A pointer set to the restart control structure - !! that will be used for MOM restart files. type(diag_ctrl), pointer :: & diag => NULL() !< A pointer to the diagnostic regulatory structure end type ocean_state_type @@ -279,7 +276,7 @@ subroutine ocean_model_init(Ocean_sfc, OS, Time_init, Time_in, wind_stagger, gas ! initialization of ice shelf parameters and arrays. call initialize_MOM(OS%Time, Time_init, param_file, OS%dirs, OS%MOM_CSp, & - OS%restart_CSp, Time_in, offline_tracer_mode=OS%offline_tracer_mode, & + Time_in, offline_tracer_mode=OS%offline_tracer_mode, & diag_ptr=OS%diag, count_calls=.true., ice_shelf_CSp=OS%ice_shelf_CSp, & waves_CSp=OS%Waves) call get_MOM_state_elements(OS%MOM_CSp, G=OS%grid, GV=OS%GV, US=OS%US, C_p=OS%C_p, & @@ -572,7 +569,7 @@ subroutine update_ocean_model(Ice_ocean_boundary, OS, Ocean_sfc, time_start_upda endif if ((OS%nstep==0) .and.

Because GV%Z_to_H is an exact power of 2 in Boussinesq mode, all answers are bitwise identical in that mode, but in non-Boussinesq mode this conversion involves multiplication and division by GV%Rho_0, so while all answers are mathematically equivalent, this change does change answers at roundoff in non-Boussinesq mode unless GV%Rho_0 is chosen to be an integer power of 2. --- src/core/MOM_variables.F90 | 28 ++++---- src/parameterizations/lateral/MOM_MEKE.F90 | 4 +- .../vertical/MOM_CVMix_KPP.F90 | 12 ++-- .../vertical/MOM_CVMix_conv.F90 | 6 +- .../vertical/MOM_CVMix_shear.F90 | 16 ++--- .../vertical/MOM_diabatic_driver.F90 | 14 ++-- .../vertical/MOM_kappa_shear.F90 | 25 +++---- .../vertical/MOM_set_diffusivity.F90 | 48 +++++++------- .../vertical/MOM_set_viscosity.F90 | 66 +++++++++---------- .../vertical/MOM_tidal_mixing.F90 | 8 +-- .../vertical/MOM_vert_friction.F90 | 34 +++++----- 11 files changed, 131 insertions(+), 130 deletions(-) diff --git a/src/core/MOM_variables.F90 b/src/core/MOM_variables.F90 index 0c4a42e8c6..199524fa33 100644 --- a/src/core/MOM_variables.F90 +++ b/src/core/MOM_variables.F90 @@ -234,12 +234,12 @@ module MOM_variables real, allocatable, dimension(:,:) :: & bbl_thick_u, & !< The bottom boundary layer thickness at the u-points [Z ~> m]. bbl_thick_v, & !< The bottom boundary layer thickness at the v-points [Z ~> m]. - kv_bbl_u, & !< The bottom boundary layer viscosity at the u-points [Z2 T-1 ~> m2 s-1]. - kv_bbl_v, & !< The bottom boundary layer viscosity at the v-points [Z2 T-1 ~> m2 s-1]. - ustar_BBL, & !< The turbulence velocity in the bottom boundary layer at h points [Z T-1 ~> m s-1]. + kv_bbl_u, & !< The bottom boundary layer viscosity at the u-points [H Z T-1 ~> m2 s-1 or Pa s] + kv_bbl_v, & !< The bottom boundary layer viscosity at the v-points [H Z T-1 ~> m2 s-1 or Pa s] + ustar_BBL, & !< The turbulence velocity in the bottom boundary layer at + !! h points [H T-1 ~> m s-1 or kg m-2 s-1].

This includes changing the units of 4 arguments to set_diffusivity; 3 arguments each to calculate_bkgnd_mixing, add_drag_diffusivity, add_LOTW_BBL_diffusivity, user_change_diff, calculate_tidal_mixing and add_int_tide_diffusivity; 2 arguments to KPP_calculate, calculate_CVMix_conv, compute_ddiff_coeffs, differential_diffuse_T_S, entrainment_diffusive, double_diffusion, add_MLrad_diffusivity, and calculate_CVMix_tidal; and one argument to energetic_PBL. The units of 36 internal variables were also changed, as were a total of 29 elements in various opaque types, including 8 elements in bkgnd_mixing_cs, 2 in diabatic_CC, 3 in tidal_mixing_diags type, 1 in user_change_diff_CS, 9 in set_diffusivity_CS type, and 6 elements in diffusivity_diags. Two new internal variables were added, and several redundant GV%H_to_Z conversion factors were also cancelled out, some using that GV%H_to_Z*GV%Rho0 = GV%H_to_RZ. Because GV%Z_to_H is an exact power of 2 in Boussinesq mode, all answers are bitwise identical in that mode, but in non-Boussinesq mode this conversion involves multiplication and division by GV%Rho_0, so while all answers are mathematically equivalent, this change does change answers at roundoff in non-Boussinesq mode unless GV%Rho_0 is chosen to be an integer power of 2. --- .../vertical/MOM_CVMix_KPP.F90 | 26 +-- .../vertical/MOM_CVMix_conv.F90 | 15 +- .../vertical/MOM_CVMix_ddiff.F90 | 10 +- .../vertical/MOM_bkgnd_mixing.F90 | 81 +++---- .../vertical/MOM_diabatic_aux.F90 | 12 +- .../vertical/MOM_diabatic_driver.F90 | 150 ++++++------ .../vertical/MOM_energetic_PBL.F90 | 4 +- .../vertical/MOM_entrain_diffusive.F90 | 14 +- .../vertical/MOM_set_diffusivity.F90 | 215 +++++++++--------- .../vertical/MOM_tidal_mixing.F90 | 90 ++++---- src/user/user_change_diffusivity.F90 | 16 +- 11 files changed, 327 insertions(+), 306 deletions(-) diff --git a/src/parameterizations/vertical/MOM_CVMix_KPP.F90 b/src/parameterizations/vertical/MOM_CVMix_KPP.F90 index f5d30029f1..5e56098c98 100644 --- a/src/parameterizations/vertical/MOM_CVMix_KPP.F90 +++ b/src/parameterizations/vertical/MOM_CVMix_KPP.F90 @@ -536,7 +536,7 @@ logical function KPP_init(paramFile, G, GV, US, diag, Time, CS, passive) 'Heat diffusivity due to KPP, as calculated by [CVMix] KPP', & 'm2/s', conversion=US%Z2_T_to_m2_s) CS%id_Kd_in = register_diag_field('ocean_model', 'KPP_Kd_in', diag%axesTi, Time, & - 'Diffusivity passed to KPP', 'm2/s', conversion=US%Z2_T_to_m2_s) + 'Diffusivity passed to KPP', 'm2/s', conversion=GV%HZ_T_to_m2_s) CS%id_Ks_KPP = register_diag_field('ocean_model', 'KPP_Ksalt', diag%axesTi, Time, & 'Salt diffusivity due to KPP, as calculated by [CVMix] KPP', & 'm2/s', conversion=US%Z2_T_to_m2_s) @@ -610,10 +610,10 @@ subroutine KPP_calculate(CS, G, GV, US, h, tv, uStar, buoyFlux, Kt, Ks, Kv, & real, dimension(SZI_(G),SZJ_(G),SZK_(GV)+1), intent(in) :: buoyFlux !< Surface buoyancy flux [L2 T-3 ~> m2 s-3] real, dimension(SZI_(G),SZJ_(G),SZK_(GV)+1), intent(inout) :: Kt !< (in) Vertical diffusivity of heat w/o KPP !!

To accommodate this change, error handling was added to detect when the THICKNESS_CONFIG and TS_CONFIG settings are incompatible. As a part of this commit the units of the h arguments to Rossby_front_initialize_thickness and Rossby_front_initialize_temperature_salinity are changed. MAXIMUM_DEPTH is now read in and rescaled via get_param in the Rossby_front routines rather than simply being pulled from the ocean grid type. There are are also changes to the units of 13 internal variables and 14 new internal variables in the Rossby_front routines. Also pass max_depth as a new argument the internal function Hml to replace the use of G%max_depth and permit simpler changes to the units being worked with. All answers are bitwise identical in Boussinesq mode, but there are substantial changes (improvements?) in answers in non-Boussinesq mode that are now independent of the value of the Boussinesq reference density. There are changes to the units of arguments to two publicly visible routines. --- .../MOM_state_initialization.F90 | 29 ++- src/user/Rossby_front_2d_initialization.F90 | 232 ++++++++++++------ 2 files changed, 179 insertions(+), 82 deletions(-) diff --git a/src/initialization/MOM_state_initialization.F90 b/src/initialization/MOM_state_initialization.F90 index 802fd33d0f..ef85607db1 100644 --- a/src/initialization/MOM_state_initialization.F90 +++ b/src/initialization/MOM_state_initialization.F90 @@ -153,7 +153,7 @@ subroutine MOM_initialize_state(u, v, h, tv, Time, G, GV, US, PF, dirs, & real :: depth_tot(SZI_(G),SZJ_(G)) !

The following diagnostics were changed from 2D (lat/lon) to 3D (lat/lon/depth): KhTr_u, KhTr_v, and KhTr_h. To preserve old answers, the values of all modified arrays are depth independent by default. The option to apply the equivalent barotropic structure as the vertical structure of the tracer diffusivity is also introduced and this can be controlled via a new parameter: KHTR_USE_EBT_STRUCT (default is false). --- src/tracer/MOM_tracer_hor_diff.F90 | 196 ++++++++++++++++++++--------- 1 file changed, 136 insertions(+), 60 deletions(-) diff --git a/src/tracer/MOM_tracer_hor_diff.F90 b/src/tracer/MOM_tracer_hor_diff.F90 index 79e99f8bb7..6f4e5d0f90 100644 --- a/src/tracer/MOM_tracer_hor_diff.F90 +++ b/src/tracer/MOM_tracer_hor_diff.F90 @@ -52,6 +52,8 @@ module MOM_tracer_hor_diff real :: max_diff_CFL !< If positive, locally limit the along-isopycnal !! tracer diffusivity to keep the diffusive CFL !! locally at or below this value [nondim]. + logical :: KhTh_use_ebt_struct !< If true, uses the equivalent barotropic structure + !! as the vertical structure of tracer diffusivity. logical :: Diffuse_ML_interior !< If true, diffuse along isopycnals between !! the mixed layer and the interior. logical :: check_diffusive_CFL !< If true, automatically iterate the diffusion @@ -135,19 +137,22 @@ subroutine tracer_hordiff(h, dt, MEKE, VarMix, G, GV, US, CS, Reg, tv, do_online real, dimension(SZI_(G),SZJ_(G)) :: & Ihdxdy, & !

When the diffusivities are depth dependent (KHTR_USE_EBT_STRUCT=True), a new array (Coef_h, with values at tracer points and at vertical interfaces) with a four-point average between Coef_x and Coef_y is introduced. This array is then used to calculate zonal and meridional neutral fluxes via optional arguments and using an existing four-point average (vertical interfaces of two tracer cells) inside subroutine neutral_surface_flux. The same approach is already used when tapering the neutral diffusive fluxes. In this case, however, the unit of the output from neutral_surface_flux (Flx) is modified because the flux of the tracer between pairs of neutral layers is multiplied by the average of Coef_h. To avoid double counting Coef_h, the code block for updating the tracer concentration from divergence of neutral diffusive flux components also had to be modified for when KHTR_USE_EBT_STRUCT=True. Similar for diagnostics trans_x_2d and trans_y_2d. This commit also makes the default value of NDIFF_DEBUG equal to the value set for DEBUG. --- src/tracer/MOM_neutral_diffusion.F90 | 370 +++++++++++++++++++-------- 1 file changed, 261 insertions(+), 109 deletions(-) diff --git a/src/tracer/MOM_neutral_diffusion.F90 b/src/tracer/MOM_neutral_diffusion.F90 index ee2d5e6a03..3b777c1453 100644 --- a/src/tracer/MOM_neutral_diffusion.F90 +++ b/src/tracer/MOM_neutral_diffusion.F90 @@ -56,6 +56,8 @@ module MOM_neutral_diffusion logical :: tapering = .false. !< If true, neutral diffusion linearly decays towards zero within a !! transition zone defined using boundary layer depths.

From e4f76c0e2fb121e2e99538925fe5fe8dbf32b396 Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Thu, 20 Jul 2023 09:31:15 -0400 Subject: [PATCH 0781/1329] +*Non-Boussinesq internal tide drag uses density Use the in situ near bottom density to calculate the internal tide drag, energy input and energy loss terms when in non-Boussinesq mode. This change includes the addition of an argument containing the near-bottom density to propagate_int_tide, itidal_lowmode_loss and find_N2_bottom. The recently added routine find_rho_bottom is used to calculate this near-bottom density. Several instances where the Boussinesq reference density or GV%Z_to_H were used have been eliminated from use in non-Boussinesq cases by this change, to simplify the code and reduce the dependence on the value of GV%Rho_0 in non-Boussinesq mode. This involved changing the units of 4 internal variables in find_N2_bottom to use thickness units or related units. In some places, GV%Rho0 was replaced with GV%H_to_RZ. It also includes the rescaling of a variable in int_tide_CS, and a new element with the bottom drag in the int_tide_input_type. All answers are bitwise identical in Boussinesq mode, but some solutions will change in non-Boussinesq mode with this change, and there are new arguments to publicly visible subroutines and a new element in a transparent type. --- .../lateral/MOM_internal_tides.F90 | 91 ++++++++++------- .../vertical/MOM_diabatic_driver.F90 | 2 +- .../vertical/MOM_internal_tide_input.F90 | 97 +++++++++++++------ 3 files changed, 121 insertions(+), 69 deletions(-) diff --git a/src/parameterizations/lateral/MOM_internal_tides.F90 b/src/parameterizations/lateral/MOM_internal_tides.F90 index 8c56107a4f..788e922ff2 100644 --- a/src/parameterizations/lateral/MOM_internal_tides.F90 +++ b/src/parameterizations/lateral/MOM_internal_tides.F90 @@ -78,9 +78,10 @@ module MOM_internal_tides real, allocatable, dimension(:,:,:,:,:) :: TKE_Froude_loss !< energy lost due to wave breaking [R Z3 T-3 ~> W m-2] real, allocatable, dimension(:,:) :: TKE_itidal_loss_fixed - !< Fixed part of the energy lost due to small-scale drag [R L-2 Z3 ~> kg m-2] here; - !!

This change only applies to the code called from the src directories, and not to code within or called directly from the config_src/drivers directories or from another component model like SIS2 where the information about whether the model is in non-Boussinesq mode is not available. A verticalGrid_type arguemnt was added to porous_barriers_init to support one of these changes. This commit will change answers in some non-Boussinesq configurations, but all answers in existing test cases appear to be bitwise identical.

As written, these could be called by any rank, and are not thread safe. In rare cases (usually related to testing), this would cause a race condition and raise an error. Even ignoring the errors, it is probably better if only one rank makes these calls, rather than all of them. The following patch modifies the function so that only root PE invokes inquire().

There are changes to the names or units of a total of 8 arguments to Stokes_PGF, Update_Stokes_Drift, Get_StokesSL_LiFoxKemper, Get_SL_Average_Prof and get_Langmuir_Number, and a new argument to StokesMixing. To accommodate these changes, there are now calls to thickness_to_dz that precede the Update_Stokes_Drift or Stokes_PGF calls and a new 3d array in step_MOM. Additionally, four hard-coded dimensional constants in Stokes_PGF were given the needed scaling factors to pass dimensional consistency testing. This change also required the addition of a unit_scale_type argument to Stokes_PGF, and corresponding changes to the calls to this routine from step_MOM_dyn_split_RK2. Three comments pointing out probable bugs or instances of inaccurate algorithms were also added. Incorrect units were also fixed in the comments describing one internal variable in Update_Stokes_Drift. Also added the new runtime parameter RHO_SFC_WAVES to set the surface seawater density that is used in comparison with the typical density of air set by RHO_AIR to estimate the 10-meter wind speed from the ocean friction velocity and the COARE 3.5 stress relationships inside of get_StokesSL_LiFoxKemper() when the Li and Fox-Kemper (2017) wave model (i.e. LF17) is used. As a part of this change, there is a new verticalGrid_type argument to the internal routine set_LF17_wave_params(). By default, RHO_SFC_WAVES is set to RHO_0. Other specific changes include: - Changed the units of the publicly visible KvS element of the wave_parameters_CS from [Z2 T-1] to [H Z T-1] - Replaced the layer thickness argument (h with units of [H ~> m or kg m-2]) to Update_Stokes_Drift(), Get_SL_Average_Prof(), get_Langmuir_Number() and Stokes_PGF() with a vertical layer extent argument (dz in units of [Z ~> m]) - Add a vertical layer extent argument (dz) to StokesMixing() - Add a unit_scale_type argument to Stokes_PGF() - Multiply a hard-coded length scale in Stokes_PGF by the correct unit scaling factor and added comments to highlight these hard-coded lengths - Corrected the unit description of the DecayScale internal variable - Changed the units of 3 internal variables and added 1 new internal variable in StokesMixing - Added two new arrays to step_MOM for the layer vertical extent and friction velocity being set via thickness_to_dz and find_ustar and being passed to Update_Stokes_Drift - Added new arrays for the layer vertical extent and calls to thickness_to_dz in KPP_compute_BLD and energetic_PBL, as well as a new dz argument to ePBL_column to provide an altered argument to get_Langmuir_Number - Use find_ustar to set the friction velocity passed to Update_Stokes_Drift - Update fluxes%ustar or fluxes%tau_mag halos as necessary when the waves are in use A total of 28 unit conversion factors were eliminated with these changes. All answers are bitwise identical in Boussinesq mode, but they are changed in non-Boussinesq mode by the use of the layer specific volume to convert between thicknesses and vertical extents. The units of several arguments to publicly visible routines are altered as is a publicly visible element in wave_parameters_CS and there is a new runtime parameter that appears in some MOM_parameter_doc files. --- src/core/MOM.F90 | 26 +++- src/core/MOM_dynamics_split_RK2.F90 | 6 +- .../vertical/MOM_CVMix_KPP.F90 | 19 ++- .../vertical/MOM_energetic_PBL.F90 | 26 ++-- src/user/MOM_wave_interface.F90 | 143 ++++++++++-------- 5 files changed, 132 insertions(+), 88 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 2f001305d1..9cbb744560 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -34,7 +34,7 @@ module MOM use MOM_error_handler, only : MOM_set_verbosity, callTree_showQuery use MOM_error_handler, only : callTree_enter, callTree_leave, callTree_waypoint use MOM_file_parser, only : read_param, get_param, log_version, param_file_type -use MOM_forcing_type, only : forcing, mech_forcing +use MOM_forcing_type, only : forcing, mech_forcing, find_ustar use MOM_forcing_type, only : MOM_forcing_chksum, MOM_mech_forcing_chksum use MOM_get_input, only : Get_MOM_Input, directories use MOM_io, only : MOM_io_init, vardesc, var_desc @@ -91,7 +91,7 @@ module MOM use MOM_grid, only : set_first_direction, rescale_grid_bathymetry use MOM_hor_index, only : hor_index_type, hor_index_init use MOM_hor_index, only : rotate_hor_index -use MOM_interface_heights, only : find_eta, calc_derived_thermo +use MOM_interface_heights, only : find_eta, calc_derived_thermo, thickness_to_dz use MOM_interface_filter, only : interface_filter, interface_filter_init, interface_filter_end use MOM_interface_filter, only : interface_filter_CS use MOM_lateral_mixing_coeffs, only : calc_slope_functions, VarMix_init, VarMix_end @@ -544,8 +544,13 @@ subroutine step_MOM(forces_in, fluxes_in, sfc_state, Time_start, time_int_in, CS ! the end of a stepping cycle (whatever that may mean). logical :: therm_reset !

My working is detailed in this document. (2) a modification to the it3 loop in shelf_calc_flux subroutine, which currently does not iterate because wB_flux does not get updated to its new value via the Newton solver method. Instead, the loop either runs 30 times with the same value, or is below the threshold and exits on the first loop. I added a line to update the value of wB_flux. Specific changes include: * Remove KV in n_star_term definition * Add line to ice shelf param it3 to correct iteration * Reinstate von Karman constant and rearrange to remove double division * Remove unneeded salt iteration line that overrides option of using false position method * Change value of ZETA_N to be consistent with Holland & Jenkins 99 * Fix typo, ZETA_N should be 0.13 not 0.013 * Add parameter for ZETA_N * Make RC and VK runtime parameters * Add runtime parameters to fix buoyancy iteration bug and salt overwriting false position method bug * Add runtime parameter for buoyancy iteration Newton's method convergence criteria --- src/ice_shelf/MOM_ice_shelf.F90 | 49 +++++++++++++++++++++++++++------ 1 file changed, 40 insertions(+), 9 deletions(-) diff --git a/src/ice_shelf/MOM_ice_shelf.F90 b/src/ice_shelf/MOM_ice_shelf.F90 index 8e0e58c1b6..d0faeb3aae 100644 --- a/src/ice_shelf/MOM_ice_shelf.F90 +++ b/src/ice_shelf/MOM_ice_shelf.F90 @@ -185,6 +185,14 @@ module MOM_ice_shelf !! salinity [C S-1 ~> degC ppt-1] real :: dTFr_dp !< Partial derivative of freezing temperature with !! pressure [C T2 R-1 L-2 ~> degC Pa-1] + real :: Zeta_N !< The stability constant xi_N = 0.052 from Holland & Jenkins '99 + !! divided by the von Karman constant VK.

This change eliminates certain dependencies on the Boussinesq reference density via GV%Z_to_H. Also added a call to calc_derived_thermo in ALE_regrid_accelerated that is necessary for the specific volume to be updated, along with tests for the validity of the specific volume with the 1-point halos that are currently used with ALE regridding and remapping. Also, use the total thickness place of the nominal depth in build_grid_rho and build_grid_sigma when in fully non-Boussinesq mode. This is mathematically equivalent but changes answers at roundoff. All answers are bitwise identical in Boussinesq mode, but ALE-based solutions change in fully non-Boussinesq mode with this commit. --- src/ALE/MOM_ALE.F90 | 5 ++- src/ALE/MOM_hybgen_unmix.F90 | 42 ++++++++++++++++++++----- src/ALE/MOM_regridding.F90 | 61 ++++++++++++++++++++++++++---------- 3 files changed, 83 insertions(+), 25 deletions(-) diff --git a/src/ALE/MOM_ALE.F90 b/src/ALE/MOM_ALE.F90 index 2e16933525..b8f60b2830 100644 --- a/src/ALE/MOM_ALE.F90 +++ b/src/ALE/MOM_ALE.F90 @@ -20,7 +20,7 @@ module MOM_ALE use MOM_hybgen_unmix, only : hybgen_unmix, init_hybgen_unmix, end_hybgen_unmix, hybgen_unmix_CS use MOM_hybgen_regrid, only : hybgen_regrid_CS use MOM_file_parser, only : get_param, param_file_type, log_param -use MOM_interface_heights,only : find_eta +use MOM_interface_heights,only : find_eta, calc_derived_thermo use MOM_open_boundary, only : ocean_OBC_type, OBC_DIRECTION_E, OBC_DIRECTION_W use MOM_open_boundary, only : OBC_DIRECTION_N, OBC_DIRECTION_S use MOM_regridding, only : initialize_regridding, regridding_main, end_regridding @@ -659,6 +659,9 @@ subroutine ALE_regrid_accelerated(CS, G, GV, US, h, tv, n_itt, u, v, OBC, Reg, d ! generate new grid if (CS%do_conv_adj) call convective_adjustment(G, GV, h_loc, tv_local) + !

The revised code uses thickness_to_dz and works with internal variables in vertical distances in the denominator of diffusive flux calculations in diabatic_ALE_legacy, diabatic_ALE and layered_diabatic. The code now uses find_ustar to extract the friction velocities passed to KPP_compute. The (tiny) boundary layer tracer diffusivity is also rescaled to [H2 T-1]. With this set of changes, all implicit references to Boussinesq reference density are eliminated from the calculations in diabatic_driver when in non-Boussinesq mode. A total of 14 thickness rescaling factors were cancelled out, and there are 15 new or renamed variables in the diabatic routines. 4 new checksum calls are also added to diabatic_ALE_legacy to assist in debugging. Because GV%Z_to_H is an exact power of 2 in Boussinesq mode, all answers are bitwise identical in that mode, but in non-Boussinesq mode the use of the layer averaged specific volume to convert thicknesses to vertical distances leads to changing answers. --- .../vertical/MOM_diabatic_driver.F90 | 170 +++++++++++------- 1 file changed, 107 insertions(+), 63 deletions(-) diff --git a/src/parameterizations/vertical/MOM_diabatic_driver.F90 b/src/parameterizations/vertical/MOM_diabatic_driver.F90 index dae52592e9..b2b8527819 100644 --- a/src/parameterizations/vertical/MOM_diabatic_driver.F90 +++ b/src/parameterizations/vertical/MOM_diabatic_driver.F90 @@ -12,8 +12,9 @@ module MOM_diabatic_driver use MOM_CVMix_ddiff, only : CVMix_ddiff_is_used use MOM_diabatic_aux, only : diabatic_aux_init, diabatic_aux_end, diabatic_aux_CS use MOM_diabatic_aux, only : make_frazil, adjust_salt, differential_diffuse_T_S, triDiagTS -use MOM_diabatic_aux, only : triDiagTS_Eulerian, find_uv_at_h, diagnoseMLDbyDensityDifference -use MOM_diabatic_aux, only : applyBoundaryFluxesInOut, diagnoseMLDbyEnergy, set_pen_shortwave +use MOM_diabatic_aux, only : triDiagTS_Eulerian, find_uv_at_h +use MOM_diabatic_aux, only : applyBoundaryFluxesInOut, set_pen_shortwave +use MOM_diabatic_aux, only : diagnoseMLDbyDensityDifference, diagnoseMLDbyEnergy use MOM_diag_mediator, only : post_data, register_diag_field, safe_alloc_ptr use MOM_diag_mediator, only : post_product_sum_u, post_product_sum_v use MOM_diag_mediator, only : diag_ctrl, time_type, diag_update_remap_grids @@ -36,14 +37,14 @@ module MOM_diabatic_driver use MOM_error_handler, only : MOM_error, FATAL, WARNING, callTree_showQuery,MOM_mesg use MOM_error_handler, only : callTree_enter, callTree_leave, callTree_waypoint use MOM_file_parser, only : get_param, log_version, param_file_type, read_param -use MOM_forcing_type, only : forcing, MOM_forcing_chksum +use MOM_forcing_type, only : forcing, MOM_forcing_chksum, find_ustar use MOM_forcing_type, only : calculateBuoyancyFlux2d, forcing_SinglePointPrint use MOM_geothermal, only : geothermal_entraining, geothermal_in_place use MOM_geothermal, only : geothermal_init, geothermal_end, geothermal_CS use MOM_grid, only : ocean_grid_type use MOM_int_tide_input, only : set_int_tide_input, int_tide_input_init use MOM_int_tide_input, only : int_tide_input_end, int_tide_input_CS, int_tide_input_type -use MOM_interface_heights, only : find_eta, calc_derived_thermo +use MOM_interface_heights, only : find_eta, calc_derived_thermo, thickness_to_dz use MOM_internal_tides, only : propagate_int_tide use MOM_internal_tides, only : internal_tides_init, internal_tides_end, int_tide_CS use MOM_kappa_shear, only : kappa_shear_is_used @@ -145,8 +146,8 @@ module MOM_diabatic_driver !! diffusivity of Kd_min_tr (see below) were operating. real :: Kd_BBL_tr !< A bottom boundary layer tracer diffusivity that !! will allow for explicitly specified bottom fluxes - !!

Specifically, it changes the units of the Kddt_smooth argument to full_convection and its counterpart in smoothed_dRdT_dRdS to use units of [H Z ~> m2 or kg s-1], which becomes a mass based diffusivity when in non-Boussinesq mode. This change also uses vertical distances for internal calculations in smoothed_dRdT_dRdS, and includes a call to thickness_to_dz in the full_convection routine. This commit also revises the unit conversion of the (absurdly large) mixing length in unstable points in full_convection and of the (tiny) added smoothing distance used in the denominators of some expressions in smoothed_dRdT_dRdS to avoid division by zero with massless layers so that they are both based on the density used in rescaling input parameters (RHO_KV_CONVERT), and do not depend directly on the Boussinesq reference density (RHO_0). These parameters would have been set via get_param calls, but there is no control structure for full_convection parameters. All Boussinesq answers are bitwise identical, but non-Boussinesq answers are altered by the use of the layer specific volumes, rather than the Boussinesq reference density, to convert layer thicknesses into vertical distances. This commit includes a change to the units of an argument (Kddt_smooth) to a publicly visible interface (full_convection). --- .../vertical/MOM_full_convection.F90 | 44 +++++++++++-------- .../vertical/MOM_set_diffusivity.F90 | 2 +- 2 files changed, 27 insertions(+), 19 deletions(-) diff --git a/src/parameterizations/vertical/MOM_full_convection.F90 b/src/parameterizations/vertical/MOM_full_convection.F90 index 344511bf29..a5fba3adc6 100644 --- a/src/parameterizations/vertical/MOM_full_convection.F90 +++ b/src/parameterizations/vertical/MOM_full_convection.F90 @@ -3,11 +3,12 @@ module MOM_full_convection !

Various kinematic viscosities are replaced with dynamic viscosities in non-Boussinesq configurations, including revising the scaled units of the viscosities to [H Z T-1 ~> m2 s-1 or Pa s]. This commit also modifies the code to explicitly use vertical distances rather than thicknesses when calculating the vertical viscous coupling coefficients in vertvisc_coef and find_coupling_coef. This commit changes the units of numerous variables to use thickness, vertical distance, dynamic viscosity or other related units, including: - 14 elements in the vertvisc_CS type - 6 arguments to the private routine find_coupling_coef - 2 arguments to the private routine find_coupling_coef_gl90 - 1 arguments ("a") to the public routine write_u_accel - 1 arguments ("a") to the public routine write_v_accel - 1 internal variable in vertvisc - 1 internal variable in vertvisc_remnant - 23 internal variables in vertvisc_coef, - 7+4+4+3 internal variables in find_coupling_coef, - 1 internal variable in find_coupling_coef_gl90 Local variables that are no longer needed were eliminated in vertvisc and vertvisc_remnant, while 2 new local variables were added to find_coupling_coef and 6 new local variables were added to vertvisc_coef. In 6 places the Boussinesq reference density was replaced with GV%H_to_RZ, which is equivalent to the reference density in Boussinesq mode, but scales to 1 in non-Boussinesq mode. The previous dimensional rescaling factor for KD_GL90 was incorrect (and inconsistent with the correct scaling factor used when reading in the analagous spatially varying kappa_gl90_2d); this has been corrected in this commit. A total of 59 GV%H_to_Z or GV%Z_to_H unit conversion factors or references to GV%Rho_0 were eliminated with these changes, and in non-Boussinesq mode there is no longer any dependence on the Boussinesq reference density. Replaced the forces argument to find_coupling_coef with an array of the friction velocities and use find_ustar to set them. When in non-Boussinesq mode, this has the effect of using forces%tau_mag and tv%SpV_avg instead of forces%ustar and GV%Rho0 when interpolating the friction velocity and stress magnitude in find_coupling_coef. Revised units used to set the GL90 viscosities and rescale to convert diagnostics of the vertical viscosities in the MOM_vert_friction module, so that they do not depend on RHO_0 when in non-Boussinesq mode. To accomodate this change in vertvisc, the units of the "a" arguments to write_u_accel and write_v_accel were also changed to use thickness-based arguments. Because GV%Z_to_H is an exact power of 2 in Boussinesq mode, all answers are bitwise identical in that mode. In non-Boussinesq mode, the answers are changed by the replacement of the Boussinesq reference density by expressions using the layer-averaged specific volumes. This commit changes the units of 2 arguments in public (diagnostic) subroutine interfaces. --- src/diagnostics/MOM_PointAccel.F90 | 14 +- .../vertical/MOM_vert_friction.F90 | 684 ++++++++++-------- 2 files changed, 403 insertions(+), 295 deletions(-) diff --git a/src/diagnostics/MOM_PointAccel.F90 b/src/diagnostics/MOM_PointAccel.F90 index d53b2e6636..e9c1092ed7 100644 --- a/src/diagnostics/MOM_PointAccel.F90 +++ b/src/diagnostics/MOM_PointAccel.F90 @@ -83,7 +83,8 @@ subroutine write_u_accel(I, j, um, hin, ADp, CDp, dt, G, GV, US, CS, vel_rpt, st real, intent(in) :: vel_rpt !< The velocity magnitude that triggers a report [L T-1 ~> m s-1] real, optional, intent(in) :: str !< The surface wind stress [R L Z T-2 ~> Pa] real, dimension(SZIB_(G),SZJ_(G),SZK_(GV)+1), & - optional, intent(in) :: a !< The layer coupling coefficients from vertvisc [Z T-1 ~> m s-1]. + optional, intent(in) :: a !< The layer coupling coefficients from vertvisc + !!

Also added new tau_mag optional arguments to the public routines allocate_forcing_by_group() and allocate_mech_forcing_by_group(), with similar mandatory arguments added to the private subroutines get_forcing_groups() and get_mech_forcing_groups(). Tests for an associated pointer were added before all calls setting the ustar, tau_mag or ustar_gustless arrays, preparing for these ustar pointers only to be set when the model is run in Boussinesq mode when the ustar actually make sense. Also use specific volume derivatives to calculate non-Boussinesq mode buoyancy fluxes in calculateBuoyancy_Flux1d, leaving the Boussinesq buoyancy flux calculations unchanged. All answers are bitwise identical in Boussinesq mode, but there is a new element in a transparent type and new optional arguments publicly visible subroutines, and answers will change in non-Boussinesq cases that depend on the surface buoyancyFlux that is returned by calculateBuoyancy_Flux1d. --- src/core/MOM_forcing_type.F90 | 226 +++++++++++++++++++++++----------- 1 file changed, 154 insertions(+), 72 deletions(-) diff --git a/src/core/MOM_forcing_type.F90 b/src/core/MOM_forcing_type.F90 index a6d35903ee..c86b9b869f 100644 --- a/src/core/MOM_forcing_type.F90 +++ b/src/core/MOM_forcing_type.F90 @@ -11,7 +11,7 @@ module MOM_forcing_type use MOM_diag_mediator, only : post_data, register_diag_field, register_scalar_field use MOM_diag_mediator, only : time_type, diag_ctrl, safe_alloc_alloc, query_averaging_enabled use MOM_diag_mediator, only : enable_averages, disable_averaging -use MOM_EOS, only : calculate_density_derivs, EOS_domain +use MOM_EOS, only : calculate_density_derivs, calculate_specific_vol_derivs, EOS_domain use MOM_error_handler, only : MOM_error, FATAL, WARNING use MOM_file_parser, only : get_param, log_param, log_version, param_file_type use MOM_grid, only : ocean_grid_type @@ -78,8 +78,11 @@ module MOM_forcing_type tau_mag => NULL(), & !< Magnitude of the wind stress averaged over tracer cells, !! including any contributions from sub-gridscale variability !! or gustiness [R L Z T-2 ~> Pa] - ustar_gustless => NULL() !< surface friction velocity scale without any + ustar_gustless => NULL(), & !< surface friction velocity scale without any !! any augmentation for gustiness [Z T-1 ~> m s-1]. + tau_mag_gustless => NULL() !< Magnitude of the wind stress averaged over tracer cells, + !! without any augmentation for sub-gridscale variability + !! or gustiness [R L Z T-2 ~> Pa] ! surface buoyancy force, used when temperature is not a state variable real, pointer, dimension(:,:) :: & @@ -989,13 +992,19 @@ subroutine calculateBuoyancyFlux1d(G, GV, US, fluxes, optics, nsw, h, Temp, Salt real, dimension(SZI_(G)) :: pressure ! pressure at the surface [R L2 T-2 ~> Pa] real, dimension(SZI_(G)) :: dRhodT ! density partial derivative wrt temp [R C-1 ~> kg m-3 degC-1] real, dimension(SZI_(G)) :: dRhodS ! density partial derivative wrt saln [R S-1 ~> kg m-3 ppt-1] + real, dimension(SZI_(G)) :: dSpV_dT !

The contents of find_N2, calculate_tidal_mixing, calculate_CVMix_tidal and add_int_tide_diffusivity are all revised to work directly with vertical distances, set via thickness_to_dz, rather than rescaled thicknesses. This includes replacing the 3-d layer thickness argument to calculate_tidal_mixing, calculate_CVMix_tidal and add_int_tide_diffusivity with a 2-d slice of vertical distances across layers. For find_N2, the 2d-slice of vertical distances is a new argument. The revised code also uses the in situ bottom density when adding certain contributions to non-Boussinesq diffusivities. This change includes the addition of a new bottom density argument to find_N2 and calculate_tidal_mixing, along with a call to find_rho_bottom to set this density. There is also a new runtime parameter, DZ_BBL_AVG_MIN, stored in set_diffusivity_CS, that helps determine the vertical extent of that average. There are a total of 6 new (or renamed) internal variables, and 6 new subroutine arguments, with revisions to the rank of one internal variable. The units of 2 internal variables and 1 element of the tidal_mixing_cs type are altered. This commit eliminates 22 factors of GV%H_to_Z and two direct uses of GV%Rho0. All answers are bitwise identical in Boussinesq mode, but solutions will change in non-Boussinesq mode with this commit. There are several new arguments to a publicly visible subroutine, and a new runtime parameter. --- .../vertical/MOM_set_diffusivity.F90 | 79 +++++--- .../vertical/MOM_tidal_mixing.F90 | 190 +++++++++--------- 2 files changed, 147 insertions(+), 122 deletions(-) diff --git a/src/parameterizations/vertical/MOM_set_diffusivity.F90 b/src/parameterizations/vertical/MOM_set_diffusivity.F90 index 32553de3d1..2aac478086 100644 --- a/src/parameterizations/vertical/MOM_set_diffusivity.F90 +++ b/src/parameterizations/vertical/MOM_set_diffusivity.F90 @@ -22,6 +22,7 @@ module MOM_set_diffusivity use MOM_forcing_type, only : forcing, optics_type use MOM_full_convection, only : full_convection use MOM_grid, only : ocean_grid_type +use MOM_interface_heights, only : thickness_to_dz, find_rho_bottom use MOM_internal_tides, only : int_tide_CS, get_lowmode_loss use MOM_intrinsic_functions, only : invcosh use MOM_io, only : slasher, MOM_read_data @@ -77,6 +78,8 @@ module MOM_set_diffusivity real :: BBL_effic !< efficiency with which the energy extracted !! by bottom drag drives BBL diffusion [nondim] real :: cdrag !< quadratic drag coefficient [nondim] + real :: dz_BBL_avg_min !< A minimal distance over which to average to determine the average + !! bottom boundary layer density [Z ~> m] real :: IMax_decay !< inverse of a maximum decay scale for !! bottom-drag driven turbulence [Z-1 ~> m-1]. real :: Kv !< The interior vertical viscosity [H Z T-1 ~> m2 s-1 or Pa s] @@ -242,8 +245,8 @@ subroutine set_diffusivity(u, v, h, u_h, v_h, tv, fluxes, optics, visc, dt, Kd_i !!

This includes the use of a layer thicknesses rather than a vertical distance in the denominator of the calculation of the buoyancy frequency and to the units of the internal rescaled gravity variable in CVMix_conv. This commit eliminates any direct or indirect dependency on the Boussinesq reference density in these 3 modules when in non-Boussinesq mode. This set of changes includes changing the units of 7 internal variables and the addition, renaming, or change in the dimensions of 4 internal variables. One element in the CVMix_ddiff_cs type is rescaled to use thickness units. These changes lead to the removal of 4 factors of GV%H_to_Z in these 3 modules. Answers will change in non-Boussinesq mode when USE_CVMix_CONVECTION, USE_CVMIX_DDIFF, USE_PP81 or USE_LMD94 are true, but they are bitwise identical in all Boussinesq test cases. --- .../vertical/MOM_CVMix_conv.F90 | 36 +++++++++++-------- .../vertical/MOM_CVMix_ddiff.F90 | 18 +++++----- .../vertical/MOM_CVMix_shear.F90 | 20 ++++++++--- 3 files changed, 46 insertions(+), 28 deletions(-) diff --git a/src/parameterizations/vertical/MOM_CVMix_conv.F90 b/src/parameterizations/vertical/MOM_CVMix_conv.F90 index c95b967681..19744cb6c5 100644 --- a/src/parameterizations/vertical/MOM_CVMix_conv.F90 +++ b/src/parameterizations/vertical/MOM_CVMix_conv.F90 @@ -11,6 +11,7 @@ module MOM_CVMix_conv use MOM_file_parser, only : openParameterBlock, closeParameterBlock use MOM_file_parser, only : get_param, log_version, param_file_type use MOM_grid, only : ocean_grid_type +use MOM_interface_heights, only : thickness_to_dz use MOM_unit_scaling, only : unit_scale_type use MOM_variables, only : thermo_var_ptrs use MOM_verticalGrid, only : verticalGrid_type @@ -163,23 +164,27 @@ subroutine calculate_CVMix_conv(h, tv, G, GV, US, CS, hbl, Kd, Kv, Kd_aux) real, dimension(SZK_(GV)+1) :: N2 !< Squared buoyancy frequency [s-2] real, dimension(SZK_(GV)+1) :: kv_col !< Viscosities at interfaces in the column [m2 s-1] real, dimension(SZK_(GV)+1) :: kd_col !< Diffusivities at interfaces in the column [m2 s-1] - real, dimension(SZK_(GV)+1) :: iFaceHeight !< Height of interfaces [m] - real, dimension(SZK_(GV)) :: cellHeight !< Height of cell centers [m] + real, dimension(SZK_(GV)+1) :: iFaceHeight !< Height of interfaces [Z ~> m] + real, dimension(SZK_(GV)) :: cellHeight !< Height of cell centers [Z ~> m] + real, dimension(SZI_(G),SZK_(GV)) :: dz !

This includes the use of a layer thicknesses rather than a vertical distance in the denominator of the calculation of the buoyancy frequency and the replacement of the layer thickness argument (h) to KPP_smooth_BLD with a layer vertical extent (dz). When in non-Boussinesq mode, the buoyancy difference between layers is normalized by the average of the density of the two layers rather than the Boussinesq reference density. This commit eliminates any direct or indirect dependency on the Boussinesq reference density in CVMix_KPP when in non-Boussinesq mode. This set of changes includes changing the units of 1 internal variables and the addition of 2 new internal variables, and a change to the name and units of one argument to KPP_smooth_BLD. These changes lead to the removal of 5 factors of GV%H_to_Z. Answers will change in non-Boussinesq mode when USE_KPP is true, but they are bitwise identical in all Boussinesq test cases. --- .../vertical/MOM_CVMix_KPP.F90 | 54 ++++++++++++------- 1 file changed, 35 insertions(+), 19 deletions(-) diff --git a/src/parameterizations/vertical/MOM_CVMix_KPP.F90 b/src/parameterizations/vertical/MOM_CVMix_KPP.F90 index d24c3e2954..303e41fc3d 100644 --- a/src/parameterizations/vertical/MOM_CVMix_KPP.F90 +++ b/src/parameterizations/vertical/MOM_CVMix_KPP.F90 @@ -625,6 +625,7 @@ subroutine KPP_calculate(CS, G, GV, US, h, tv, uStar, buoyFlux, Kt, Ks, Kv, & !

These changes include using the specific volume interpolated to velocity points for the conversion between thickness and height changes when tv%SpV_avg is allocated, including in the calculation of the rescaled ustar in the top and bottom boundary layers and in the Rayleigh drag calculation. In set_viscous_ML, the derivatives of specific volume are used to determine the reduced gravity across interfaces when in non-Boussinesq mode. Both set_viscous_BBL and set_viscous_ML now work extensively in height units rather than thickness units in various places where it is more appropriate to do so when in non-Boussinesq mode, and both use calls to thickness_to_dz to convert between thicknesses and vertical distances. In some places this leads to extra calculations using separate arrays that are rescaled duplicates of each other in Boussinesq mode, which will probably slow the model down a little. There is one rescaling bug due to a hard-coded unrescaled dimensional constant that was fixed. It occurs when setting a tiny floor in a thickness in one inverse calculation. However, this appears to be so small that it does not change any answers in the MOM6-examples test suite, and could only do so if ANGSTROM is set to be many orders of magnitude less than the typical value of 1e-10 m, so it was decided that no runtime bug-flag is needed in this case. A call to find_star is now used to specify the friction velocity used in set_viscous_ML. When in non-Boussinesq mode, this has the effect of using forces%tau_mag and tv%SpV_avg instead of forces%ustar and GV%Rho0 to determine the friction velocity. In set_viscous_BBL the layer specific volumes are used in non-Boussinesq mode to find the average velocities used in the linearization of the nonlinear bottom drag, with similar changes in set_viscous_ML for the drag under ice-shelves. When in non-Boussinesq mode, the units of Kd_shear, Kv_shear and Kv_shear_Bu in the restart files are scaled to their natural MKS units of [Pa s] or [kg m-1 s-1] rather than [m2 s-1] to avoid round-off level changes across restarts, with the units in the files documenting these changes. These altered units do not apply to Boussinesq mode restart files. In set_visc_init, the rescaling factor used to set CS%Hbbl was changed from GV%Z_to_H to (US%Z_to_m*GV%m_to_H) so that it does not depend directly on RHO_0. These changes are extensive but localized to this file, with one new element of the opaque set_visc_CS type and 6 elements with altered units, 37 new or renamed internal variables, and 29 existing internal variables that have revised units. In particular one extensively used thickness curvature variable that had been called just "a" was renamed "crv" to more accurately reflect its purpose and to make it easier to find when rescaling it, with similar changes to two other closely related variables. These changes include the elimination of 29 rescaling factors between thickness and height units, as were two spots that inappropriately (and unnecessarily, as it turns out) used GV%Rho0 even when in non-Boussinesq mode. There are also 4 new debugging checksum output calls. In Boussinesq or semiBoussinesq mode, no public interfaces are changed and all answers are bitwise identical, but in non-Boussinesq mode answers will change and there are changes to the units of 3 variables in restart files. --- .../vertical/MOM_set_viscosity.F90 | 731 ++++++++++++------ 1 file changed, 474 insertions(+), 257 deletions(-) diff --git a/src/parameterizations/vertical/MOM_set_viscosity.F90 b/src/parameterizations/vertical/MOM_set_viscosity.F90 index 9ab300560b..9a99bc6b26 100644 --- a/src/parameterizations/vertical/MOM_set_viscosity.F90 +++ b/src/parameterizations/vertical/MOM_set_viscosity.F90 @@ -6,30 +6,30 @@ module MOM_set_visc use MOM_ALE, only : ALE_CS, ALE_remap_velocities, ALE_remap_interface_vals, ALE_remap_vertex_vals use MOM_cpu_clock, only : cpu_clock_id, cpu_clock_begin, cpu_clock_end, CLOCK_ROUTINE +use MOM_cvmix_conv, only : cvmix_conv_is_used +use MOM_CVMix_ddiff, only : CVMix_ddiff_is_used +use MOM_cvmix_shear, only : cvmix_shear_is_used use MOM_debugging, only : uvchksum, hchksum use MOM_diag_mediator, only : post_data, register_diag_field, safe_alloc_ptr use MOM_diag_mediator, only : diag_ctrl, time_type use MOM_domains, only : pass_var, CORNER +use MOM_EOS, only : calculate_density, calculate_density_derivs, calculate_specific_vol_derivs use MOM_error_handler, only : MOM_error, FATAL, WARNING use MOM_file_parser, only : get_param, log_param, log_version, param_file_type -use MOM_forcing_type, only : forcing, mech_forcing +use MOM_forcing_type, only : forcing, mech_forcing, find_ustar use MOM_grid, only : ocean_grid_type use MOM_hor_index, only : hor_index_type +use MOM_interface_heights, only : thickness_to_dz use MOM_io, only : slasher, MOM_read_data use MOM_kappa_shear, only : kappa_shear_is_used, kappa_shear_at_vertex -use MOM_cvmix_shear, only : cvmix_shear_is_used -use MOM_cvmix_conv, only : cvmix_conv_is_used -use MOM_CVMix_ddiff, only : CVMix_ddiff_is_used +use MOM_open_boundary, only : ocean_OBC_type, OBC_segment_type, OBC_NONE, OBC_DIRECTION_E +use MOM_open_boundary, only : OBC_DIRECTION_W, OBC_DIRECTION_N, OBC_DIRECTION_S use MOM_restart, only : register_restart_field, query_initialized, MOM_restart_CS use MOM_restart, only : register_restart_field_as_obsolete use MOM_safe_alloc, only : safe_alloc_ptr, safe_alloc_alloc use MOM_unit_scaling, only : unit_scale_type use MOM_variables, only : thermo_var_ptrs, vertvisc_type, porous_barrier_type use MOM_verticalGrid, only : verticalGrid_type -use MOM_EOS, only : calculate_density, calculate_density_derivs -use MOM_open_boundary, only : ocean_OBC_type, OBC_NONE, OBC_DIRECTION_E -use MOM_open_boundary, only : OBC_DIRECTION_W, OBC_DIRECTION_N, OBC_DIRECTION_S -use MOM_open_boundary, only : OBC_segment_type implicit none ; private @@ -48,6 +48,8 @@ module MOM_set_visc logical :: initialized = .false. !< True if this control structure has been initialized. real :: Hbbl !< The static bottom boundary layer thickness [H ~> m or kg m-2]. !!

From 9b86edb3d8f0acb13cfaa610cad17b4a740d7bd2 Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Sat, 12 Aug 2023 11:55:57 -0400 Subject: [PATCH 0804/1329] *Non-Boussinesq revision of set_diffusivity This commit revises the internal routines called by set_diffusivity to work in fully non-Boussinesq mode, eliminating all dependencies on the Boussinesq reference density when in non-Boussinesq mode. The publicly visible interfaces to this module and the external routines it calls have already been revised, so only this file needs to be updated. The specific changes include: - Refactored add_LOTW_BBL_diffusivity, add_MLrad_diffusivity, and set_BBL_TKE to work in units of layer vertical extent rather than layer thickness to give results in non-Boussinesq mode that avoid dependence on the Boussinesq reference density. - Work with internal variables in vertical distances in the denominator of diffusive flux calculations in find_TKE_to_Kd, while other expressions in this routine are recast in terms of thicknesses to avoid conversions. - Use tv%SpV_avg instead of 1/RHO_0 in find_TKE_to_Kd when in fully non-Boussinesq mode. - Use layer target density differences in place of g_prime in set_density_ratios in mathematically equivalent expressions when non-Boussinesq. - Use thickness_to_dz in 3 places to convert layer thicknesses into vertical distances. - The thickness argument to add_MLrad_diffusivity (in [H ~> m or kg m-2]) has been replaced with a vertical extent argument (in [Z ~> m]). - Use fluxes%tau_mag in place of fluxes%ustar in add_MLrad_diffusivity when in non-Boussinesq or semi-Boussinesq mode. There is a new thermo_var_ptrs type argument to the internal routine add_MLrad_diffusivity to permit this changes. - Use the in situ near-bottom density when adding certain contributions to non-Boussinesq diffusivities. This change includes the addition of a new bottom density (rho_bot) argument to add_int_tide_diffusivity, add_LOTW_BBL_diffusivity and add_drag_diffusivity. - Use GV%dZ_subroundoff in 4 spots in place of GV%H_to_Z*GV%H_subroundoff. - A long-standing comment questioning whether there is double-counting of tidal mixing has been addressed (there is not) and the comment has been revised accordingly. These changes involved changing the units of 21 internal variables and 1 element in the set_diffusivity_CS type. There are 11 new internal variables, while 9 internal variables were eliminated. A total of 44 thickness rescaling factors were eliminated, and there are 2 places where GV%Rho_0 was being used explicitly that were changed into equivalent rescaling factors. All answers are bitwise identical in Boussinesq mode, but some solutions will change in non-Boussinesq mode with this commit. --- .../vertical/MOM_set_diffusivity.F90 | 341 ++++++++++-------- 1 file changed, 200 insertions(+), 141 deletions(-) diff --git a/src/parameterizations/vertical/MOM_set_diffusivity.F90 b/src/parameterizations/vertical/MOM_set_diffusivity.F90 index 2aac478086..c792f5200e 100644 --- a/src/parameterizations/vertical/MOM_set_diffusivity.F90 +++ b/src/parameterizations/vertical/MOM_set_diffusivity.F90 @@ -80,8 +80,8 @@ module MOM_set_diffusivity real :: cdrag !< quadratic drag coefficient [nondim] real :: dz_BBL_avg_min !< A minimal distance over which to average to determine the average !! bottom boundary layer density [Z ~> m] - real :: IMax_decay !< inverse of a maximum decay scale for - !! bottom-drag driven turbulence [Z-1 ~> m-1]. + real :: IMax_decay !< Inverse of a maximum decay scale for + !! bottom-drag driven turbulence [H-1 ~> m-1 or m2 kg-1]. real :: Kv !< The interior vertical viscosity [H Z T-1 ~> m2 s-1 or Pa s] real :: Kd !< interior diapycnal diffusivity [H Z T-1 ~> m2 s-1 or kg m-1 s-1] real :: Kd_min !< minimum diapycnal diffusivity [H Z T-1 ~> m2 s-1 or kg m-1 s-1] @@ -505,8 +505,9 @@ subroutine set_diffusivity(u, v, h, u_h, v_h, tv, fluxes, optics, visc, dt, Kd_i endif !

This commit includes making the formerly optional arguments kb_out, Kd_Lay and Kd_int to entrainment_diffusive non-optional, as they have been used in all calls to this routine for many years. Layer target density differences are now used in place of g_prime in entrainment_diffusive in mathematically equivalent expressions for the density difference ratios when non-Boussinesq. The non-Boussinesq upper layer buoyancy flux with entrainment_diffusive was revised to avoid using the Boussinesq reference density when the model is in layered mode but there is no equation of state or bulk mixed layer in use. The units of 3 internal variables were changed and there are 3 new internal variables as a part of these changes, and 4 thickness rescaling factors were eliminated. A default private setting is used to simplify a block of OMP directives. All answers are bitwise identical in Boussinesq mode, but they can change for some non-Boussinesq configurations, and three previously optional arguments have been made mandatory. --- .../vertical/MOM_entrain_diffusive.F90 | 182 ++++++++++-------- 1 file changed, 105 insertions(+), 77 deletions(-) diff --git a/src/parameterizations/vertical/MOM_entrain_diffusive.F90 b/src/parameterizations/vertical/MOM_entrain_diffusive.F90 index c30f5c2c3f..de13322652 100644 --- a/src/parameterizations/vertical/MOM_entrain_diffusive.F90 +++ b/src/parameterizations/vertical/MOM_entrain_diffusive.F90 @@ -5,14 +5,15 @@ module MOM_entrain_diffusive use MOM_diag_mediator, only : post_data, register_diag_field, safe_alloc_ptr use MOM_diag_mediator, only : diag_ctrl, time_type +use MOM_EOS, only : calculate_density, calculate_density_derivs +use MOM_EOS, only : calculate_specific_vol_derivs, EOS_domain use MOM_error_handler, only : MOM_error, is_root_pe, FATAL, WARNING, NOTE -use MOM_file_parser, only : get_param, log_version, param_file_type -use MOM_forcing_type, only : forcing -use MOM_grid, only : ocean_grid_type -use MOM_unit_scaling, only : unit_scale_type -use MOM_variables, only : thermo_var_ptrs -use MOM_verticalGrid, only : verticalGrid_type -use MOM_EOS, only : calculate_density, calculate_density_derivs, EOS_domain +use MOM_file_parser, only : get_param, log_version, param_file_type +use MOM_forcing_type, only : forcing +use MOM_grid, only : ocean_grid_type +use MOM_unit_scaling, only : unit_scale_type +use MOM_variables, only : thermo_var_ptrs +use MOM_verticalGrid, only : verticalGrid_type implicit none ; private @@ -73,14 +74,13 @@ subroutine entrainment_diffusive(h, tv, fluxes, dt, G, GV, US, CS, ea, eb, & intent(out) :: eb !< The amount of fluid entrained from the layer !! below within this time step [H ~> m or kg m-2]. integer, dimension(SZI_(G),SZJ_(G)), & - optional, intent(inout) :: kb_out !< The index of the lightest layer denser than + intent(inout) :: kb_out !< The index of the lightest layer denser than !! the buffer layer. - !

It uses different inputs, different parameters, filters the BLD differently, - Renamed mixedlayer_restrat_general to mxiedlayer_restrat_OM4 to better distinguish the two versions. - Added function rmean2ts to extend the resetting running-mean time filter used in OM4 to use different time scales when growing or decaying. While mathematically the same in the limit of a zero "growing" time-scale, the implementation differs in the use of a reciprocal instead of division so was not added to the OM4 version. - Updated module documentation Co-authored-by: Abigail Bodner * Add Bodner MLE testing This patch adds the Bodner MLE testing parameters to the tc2.a test. * +Add Pa_to_RL2_T2 and Pa_to_RLZ_T2 to US type Add the combined unit scaling factors Pa_to_RL2_T2 and Pa_to_RLZ_T2 to the unit_scale_type to rescale pressures and wind stresses. All answers are bitwise identical, but there are two new elements in a public type. * Use US%Pa_to_RL2_T2 to rescale pressures Use the new combined unit scaling factor US%Pa_to_RL2_T2 to rescale input pressure fields and US%Pa_to_RLZ_T2 to rescale input wind stresses in various places in the MOM6 code, including in the solo_driver and FMS_cap drivers. Analogous changes could also be made to the mct and nuopc surface forcing files, but have been omitted for now. All answers are bitwise identical. * +Add runtime parameter TAUX_MAGNITUDE Added the new runtime parameter TAUX_MAGNITUDE to set the strength of the zonal wind stresses when WIND_CONFIG = "2gyre", "1gyre" or "Neverworld", with a default that matches the previous hard-coded dimensional parameters that were used to specify the wind stresses in these cases. Also use US%Pa_to_RLZ_T2 to rescale wind stresses throughout solo_driver/MOM_surface_forcing.F90. By default, all answers are bitwise identical, but there is a new runtime parameter in the MOM_parameter_doc files for some test cases. * Correct MLD_EN_VALS rescaling Correct inconsistent dimensional rescaling of the input values of MLD_EN_VALS, setting them all to [R Z3 T-2 ~> J m-2] to reflect that these are energies associated with vertical turbulent mixing. This fixes a rescaling bug when these energies are set to non-default values at runtime, but all answers and output are bitwise identical when no rescaling is used. * Add better error handling to read_var_sizes Add better error handling to read_var_sizes when a missing file or missing variable is provided as an argument. Without this change the model fails with a segmentation fault on line 768 of MOM_io.F90 if a bad file or variable name is provided. With this change, a useful error message is returned. All answers are bitwise identical in all cases that worked previously. * Checksum unrescaled non-Boussinesq thicknesses Redid the scaling of 52 checksum or check_redundant calls for thickness or transports to use the MKS counterparts of the thickness units (i.e., m and m3/s or kg/m2 and kg/s, depending on the Boussinesq approximation), rather than always rescaling them to m or m3/s. In Boussinesq mode, everything remains the same, but in non-Boussinesq mode, this means that the model's actual variable are being checksummed and not a version that is rescaled by division by the (meaningless?) Boussinesq reference density. All solutions are bitwise identical, but some debugging output will change in non-Boussinesq mode. * (*)Use conversion factor for masscello diagnostic Use a conversion factor to rescale the units of masscello, just like every other diagnostic. This does not change the diagnostic itself, but it changes the order of the rescaling and the vertical remapping of this diagnostic onto other coordinates (like z) or spatial averaging of this diagnostic, which can change values in the last bits for this diagnostic for Boussinesq models (but not for non-Boussinesq models, for which the conversion factor is an integer power of 2). As a result some of the diagnostics derived from masscello can differ and this commit nominally fails the TC testing for reproducibility across code versions. All solutions and primary diagnostics, however, are bitwise identical, and even the derived diagnostic calculations are mathematically equivalent. * +Remove rescaling factors from restart files Remove the code to account for unit rescaling within the restart files. This rescaling within the restart files has not been used in the code since March, 2022, and the model will work with older restart files provided that they did not use dimensional rescaling, and even if they did they can be converted not to use rescaling with a short run with the older code that created them. Also removed the publicly visible routines fix_restart_scaling and eliminated the m_to_H_restart element of the verticalGrid_type; in any cases of non-standard code using this element, it should be replaced with 1.0. The various US%..._restart elements and fix_restart_unit_scaling are being retained for now because they are still being used in the SIS2 code. These changes significantly simplify the code, and they lead to a handful of constants that are always 1 not being included in the MOM6 restart files. All answers are bitwise identical, but a publicly visible interface has been eliminated, as has been an element (GV%m_to_H_restart) of a transparent type. * +Add MOM_EOS_Wright_Full Added the new module MOM_EOS_Wright_full to enable the use of the version of the Wright equation of state that has been fit over the larger range of temperatures (-2 degC to 40 degC), salinities (0 psu to 40 psu) and pressures (0 dbar to 10000 dbar), than the does the restricted range fit in MOM_EOS_Wright, which had been fit over the range of (-2 degC to 30 degC), (28 psu to 38 psu) and (0 to 5000 dbar). Comments have been added to both modules to clearly document the range of properties over which they have been fitted. The new equation of state is enabled by setting EQN_OF_STATE = "WRIGHT_FULL". In addition, the default values for TFREEZE_FORM and EOS_QUADRATURE were changed depending on the equation of state to avoid having defaults that lead to fatal errors. All answers are bitwise identical in any cases that currently work, but there are new entries in the MOM_parameter_doc files. For now, only the coefficients have been changed between MOM_EOS_Wright and MOM_EOS_Wright_full, but this means that it does not yet have all of the parentheses that it should, as github.com/mom-ocean/MOM6/issues/1331 discusses. A follow up PR should add appropriate self-consistency and reference value checks (with a tolerance) for the various EOS routines, and then add enough parentheses to specify the order of arithmetic and hopefully enhance the accuracy. Ideally this can be done with the new equation of state before it starts to be widely used, so that we can avoid needing a extra code to reproduce the older answers. * Fix and tidy Wright_EOS API documentation Cleaned up the comments describing the routines and added a proper doxygen namespace block at the end of the MOM_EOS_Wright and MOM_EOS_Wright_full modules, based on changes that A. Adcroft had on a detached branch of MOM6. Only comments are changed, and all answers are bitwise identical. * (*)Rearranged parentheses in MOM_EOS_Wright_full Added parentheses to all expressions with three or more additions or multiplications in the MOM_EOS_Wright_full code, so that different compilers and compiler settings will reproduce the same answers in more cases. In doing this, an effort was made to add the smallest terms first to reduce the impact of roundoff. In some cases, the code was deliberately rearranged to cancel out the leading order terms more completely. In addition, two bugs had been identified in calculate_density_second_derivs_wright_full. These were corrected and the entire routine substantially refactored with renamed variables to make the derivation easier to follow and verify. Apart from the bug corrections in the calculation of drho_dt_dt and drho_dt_dp, the changes in the expressions are mathematically equivalent, but they might make the model less noisy in some cases by reducing contributions from round-off errors. Also added comments highlighting two bugs in the drho_dt_dt and drho_dt_dp calculations in calculate_density_second_derivs_wright in the original MOM_EOS_Wright code, but did not correct them to preserve the previous answers. * +Created the new module MOM_EOS_Wright_red Created a new module, MOM_EOS_Wright_red, that uses the reduced range fit coefficients from the Wright EOS paper, but uses the parentheses, expressions and bug fixes that are now in MOM_EOS_Wright_full. To use this new module, set EQN_OF_STATE="WRIGHT_RED". This new form is mathematically equivalent using EQN_OF_STATE="WRIGHT" (apart from correcting the bugs in the calculations of drho_dt_dt and drho_dt_dp), but the order of arithmetic is different, so the answers will differ. This change is probably as close as we can come to addressing the issues discussed at github.com/mom-ocean/MOM6/issues/1331, so that issue should be closed once this commit is merged onto the main branch. Also corrected some misleading error messages in MOM_EOS and modified the code to properly handle the case for equations of state (like NEMO and UNESCO) that do not have a scalar form of calculate_density_derivs, but do have an array form. By default, all answers are bitwise identical. * *Fix bug in calculate_spec_vol_linear with spv_ref Corrected a sign error in calculate_spec_vol_array_linear and calculate_spec_vol_scalar_linear when a reference specific volume is provided. This bug will cause any configurations with EQN_OF_STATE="LINEAR" and BOUSSINESQ=False (neither of which is the default value) to have the wrong sign of the pressure gradients and other serious problems, like implausible sea surface and internal interface heights. This combination of parameters would never be used in a realistic ocean model. There are no impacted cases in any of the MOM6-examples tests cases, nor those used in the ESMG or dev/NCAR test suites, and it is very unlikely that any such case would work at all. This bug was present in the original version of the calculate_spec_vol_linear routines, but it was only discovered after the implementation of the comprehensive equation of state unit testing. This will change answers in configurations that could not have worked as viable ocean models, but answers are not impacted in any known configuration, and all solutions in test cases are bitwise identical. * +Add EOS_unit_tests Added the new publicly visible function EOS_unit_tests, along with a call to it from inside of unit_tests. These tests evaluate check values for density and assess the consistency of expressions for variables that can be derived from density with finite-difference estimates of the same variables. These tests reveal inconsistencies or omissions with several of the options for the equation of state. The EOS self-consistency tests that are failing are commented out for now, so that this redacted unit test passes. All answers are bitwise identical, but there can be new diagnostic messages written out. * Fix doxygen labels in EOS_Wright_full and _red Changed recently added doxygen labels in the two newly added EOS_Wright_red and EOS_Wright_full modules to avoid reusing names that were already being used by EOS_Wright. All answers are bitwise identical, but the doxygen testing that had been failing for the previous 5 commits is working again. * *+NEMO equation of state self-consistency Corrected numerous issues with the NEMO equation of state so that it is now self consistent: - Modified how coefficients are set in MOM_EOS_NEMO so that they are guaranteed to be internally self-consistent, as verified by the EOS unit tests confirming that the first derivatives of density with temperature and salinity are now consistent with the equation of state. Previously these had only been consistent to about 7 decimal places, and hence the EOS unit tests were failing for the NEMO equation of state. - Added new public interfaces to calculate_density_second_derivs_NEMO, which had previously been missing. - Added code for calculate_compress_nemo that is explicitly derived from the NEMO EOS. The previous version of calculate_compress_nemo had worked only approximately via a call to the gsw package With these changes, the NEMO EOS routines are now passing the consistency testing in the EOS unit tests. Answers will change for configurations that use the NEMO EOS to calculate any derivatives, and there are new public interfaces, but it does not appear that the NEMO equation of state is in use yet, at least it is not being used at EMC, FSU, GFDL, NASA GSFC, NCAR or in the ESMG configurations. This commit addresses the issue raised at github.com/mom-ocean/MOM6/issues/405. * +Add calculate_density_second_derivs_UNESCO Added the new public interface calculate_density_second_derivs_UNESCO, which is an overload for both scalar and array versions, to calculate the second derivatives of density with various combinations of temperature, salinity and pressure. Also added a doxygen block at the end of MOM_EOS_UNESCO.F90 to describe this module and the papers it draws upon. Also replaced fatal errors in MOM_EOS with calls to these new routines. All answers are bitwise identical, but there are newly permitted combinations of options that previously failed. * (*)+Added calc_density_second_derivs_wright_buggy Added the new public interface calc_density_second_derivs_wright_buggy to reproduce the existing answers and corrected bugs in the calculation of the second derivatives of density with temperature and with temperature and pressure in in calculate_density_second_derivs_wright. Also added the new runtime parameter USE_WRIGHT_2ND_DERIV_BUG to indicate that the older (buggy) version of calculate_density_second_derivs_wright is to be used. Most configurations will not be impacted, but by default answers will change with configurations that use the Wright equation of state and one of the Stanley or similar nonlinear EOS parameterizations, unless USE_WRIGHT_2ND_DERIV_BUG is explicitly set to True. This commit also activates the self-consistency unit testing with the Wright equation of state (now that it passes) and limited unit testing of the TEOS-10 equation of state, omitting the second derivative calculations, one of which is failing (the second derivative of density with salinity and pressure) due to a bug in the TEOS10/gsw code. Also added a unit test for consistency of the density and specific volume when an offset reference value is used. * *Refactor MOM_EOS_UNESCO.F90 Refactored the expressions in MOM_EOS_UNESCO.F90, adding parentheses to specify the order of arithmetic, starting with the highest-order terms first for less sensitivity to round-off. Also added comments to better describe the references for these algorithms. Although the revised expressions are all mathematically equivalent, this commit will change answers for any cases that use EQN_OF_STATE = "UNESCO". However, it is believed based on a survey of the MOM6 community that there are no active configurations that use this equation of state. * *Refactor MOM_EOS_NEMO.F90 Refactored the expressions in MOM_EOS_NEMO.F90, adding parentheses to specify the order of arithmetic, starting with the highest-order terms first for less sensitivity to round-off. A number of internal variables were also renamed for greater clarity, and a number of comments were revised to better describe the references for these algorithms.. Although the revised expressions are all mathematically equivalent, this commit will change answers for any cases that use EQN_OF_STATE = "NEMO". However, there is another recent commit to this file that also changes answers (specifically the density derivatives) with this equation of state, and it is believed based on a survey of the MOM6 community that there are no active configurations that use this equation of state. * +Add MOM_EOS_Roquet_SpV.F90 Added the new equation of state module MOM_EOS_Roquet_SpV with the polynomial specific volume fit equation of state from Roquet et al. (2015). This equation of state has also been added to MOM_EOS, where it is enabled by setting EQN_OF_STATE="ROQUET_SPV". Two other new valid settings have been added to EQN_OF_STATE, "ROQUET_RHO" and "JACKETT_MCD", which synonymous with "NEMO" and "UNESCO" respectively, but more accurately reflect the publications that describe these fits to the equation of state. The EoS unit tests are being called for the new equation of state (it passes). By default, all answers are bitwise identical, but there are numerous new publicly visible interfaces. * +Add MOM_EOS_Jackett06.F90 Added the new equation of state module MOM_EOS_Jackett06 with the rational function equation of state from Jackett et al. (2006). This uses potential temperature and practical salinity as state variables, but with a fit to more up-to-date observational data than Wright (1997) or UNESCO / Jackett and McDougall (1995). This equation of state has also been added to MOM_EOS, where it is enabled by setting EQN_OF_STATE="JACKETT_06". The EoS unit tests are being called for the new equation of state (it passes). This commit also adds slightly more output from successful EoS unit tests when run with typical levels of verbosity. By default, all answers are bitwise identical, but there are numerous new publicly visible interfaces. * *+Add calculate_specvol_derivs_UNESCO Added the routine calculate_specvol_derivs_UNESCO to calculate the derivatives of specific volume with temperature and salinity to the MOM_EOS_UNESCO module. Also added some missing parentheses elsewhere in this module so that the answers will be invariant to complier version and optimization levels. Also revised the internal nomenclature of the parameters in this module to follow the conventions of the other EOS modules. Although the revised expressions are mathematically equivalent, this commit will change answers for any cases that use EQN_OF_STATE = "UNESCO". However, it is believed based on a survey of the MOM6 community that there are no active configurations that use this equation of state. There is a new publicly visible routine. * +Add EOS_fit_range and analogs for each EoS Added the new publicly visible subroutine EOS_fit_range and equivalent routines for each of the specific equation of state modules to return the range of temperatures, salinities, and pressures over which the observed data have been fitted. This is also tested for in test_EOS_consistency to indicate whether a test value is outside of the fit range, but the real purpose will be to flag and then figure out how to deal with the case when the ocean model is called with properties for which the equation of state is not valid. Note that as with all polynomial or other functional fits, extrapolating far outside of the fit range is likely to lead to bad values, but things may not be so bad for values that are only slightly outside of this range. However the question of how far out of the fit range these EoS expressions become inappropriate for each of temperature, salinity and pressure is as yet unresolved. All answers and output are bitwise identical, but there are 10 new public interfaces. * Do not include MOM_memory.h in EoS modules Removed unused and unnecessary #include statements from 5 equation of state modules. All answers are bitwise identical. * *Refactor calculate_specific_vol_wright_full Refactored the specific volume calculations for the WRIGHT_FULL and WRIGHT_RED equations of states for simplicity or to reduce the impacts of roundoff when removing a reference value. Also added code to multiply by the reciprocal of the denominator rather than dividing in several places in the int_spec_vol_dp routines for these same two equations of state, both for efficiency and greater consistency across optimization levels. These changes are mathematically equivalent but will change answers at roundoff with these two equations of state, but they are so new that they can not have been used yet. * +Renamed MOM_EOS_NEMO to MOM_EOS_Roquet_rho Renamed the module MOM_EOS_NEMO to MOM_EOS_Roquet_rho to more accurately reflect its provenance, although setting either EQN_OF_STATE = NEMO or EQN_OF_STATE = ROQUET_RHO will still work for using this code. All answers are bitwise identical, and previous input files will still work, but there are some minor changes in the MOM_parameter_doc files. * *Avoid re-rescaling T and p in MOM_EOS_Roquet_rho Refactored MOM_EOS_Roquet_rho and MOM_EOS_Roquet_SpV to work directly with conservative temperatures in [degC] and pressures in [Pa] rather than normalizing them as in the original Roquet publication. However, the coefficients are still set using the values directly copied from that paper, but rescaled where they are declared as parameters, enabling (or requiring) compilers to precalculate them during compilation. These changes are mathematically equivalent but will change answers at roundoff with these two equations of state, but they are not believed to be in use yet. * +Add calculate_TFreeze_TEOS_poly Added the overloaded interface calculate_TFreeze_TEOS_poly to MOM_TFreeze to use the 23-term polynomial expression from TEOS-10 for the freezing point in conservative temperature as a function of pressure and absolute salinity. This gives results that agrees to within about 5e-4 degC with the algorithm used by calculate_TFreeze_TEOS10, which calls the gsw TEOS10 code that does an iterative inversion of a balance of chemical potentials to find the freezing point (see the TEOS10 documentation for more details). Also added testing for the freezing point calculations to the EOS_unit tests via the new internal subroutine test_TFr_consistency. This new freezing point calculation is invoked by setting TFREEZE_FORM = TEOS_POLY. By default, all answers are bitwise identical, but there are some minor changes in the comments in some MOM_parameter_doc files, and there are several new interfaces. * +*Add MOM_temperature_convert.F90 Added the new module MOM_temperature_convert, which contains the elemental functions poTemp_to_consTemp and consTemp_to_poTemp to convert potential temperature to conservative temperature and the reverse. These routines are mathematically equivalent to the TEOS-10 functions gsw_ct_from_pt and gsw_pt_from_ct, but with some refactoring and added parentheses to help ensure identical answers across compilers or levels of optimization. Also added the new subroutines pot_temp_to_cons_temp and prac_saln_to_abs_saln, and added the new optional argument use_TEOS to convert_temp_salt_for_TEOS10, and cons_temp_to_pot_temp and abs_saln_to_prac_saln. The equivalency between the new code and their gsw_ counterparts is demonstrated in new tests in the new function test_TS_conversion_consistency, which in turn is called from EOS_unit_tests. All answers are mathematically equivalent, but because of the choice to use the new code by default there could be changes at the level of roundoff in some cases that use conservative temperature as their state variable but initialize it from potential temperature. There are not any such cases yet in the MOM6-examples test suite, nor are there believed to be any such MOM6 configurations that are widely used. This commit introduces a new module and several new functions or subroutines with public interfaces. * Update _Equation_of_State.dox Updated _Equation_of_State.dox to reflect the new options for the equation of state and freezing point calculations. * +Eliminate use_TEOS arg to cons_temp_to_pot_temp Eliminate use_TEOS optional arguments that were recently added to cons_temp_to_pot_temp and 4 other thermodynamic variable conversion functions, along with calls to gsw_pt_to_ct and similar conversion functions. All answers in the MOM6-examples test suite are bitwise identical. * +Make calculate_density_array private Removed calculate_density_array from the overloaded public calculate_density interface, and similarly for the other EOS calculate_..._array routines, to help standardize how they are called. Calculate_density_derivs_array is the one exception is because it is being called from SIS2 and has to stay publicly visible for now. Additionally, the scalar and 1-d versions of the calculate_stanley_density routines were refactored to just use calculate_density and calculate_density_second_derivs call and avoid any EoS-specific logic, while the unused routine calculate_stanley_density_array is eliminated altogether. All answers are bitwise identical, including in extra tests that use the stanley_density routines. * +Rename WRIGHT_RED to WRIGHT_REDUCED Revised the setting EQN_OF_STATE to select the Wright equation of state with the reduced-range fit to "WRIGHT_REDUCED" (instead of "WRIGHT_RED") for greater clarity, in response to a comment in the review of the pull request with this sequence of code revisions. All answers are bitwise identical, but this changes the text for a recently added input parameter and it leads to changes in some comments in the MOM_parameter_doc files. * Removal of FMS1 I/O from FMS2 I/O infra This patch removes the calls to FMS1 I/O (fms_io_mod, mpp_io_mod) from the FMS2 infra layer, and now exclusively uses FMS2 for those operations. FMS2 I/O is currently restricted to files which use domains; files which do not use them are delegated to the native netCDF layer. The reasoning for this is that FMS is required to define the formatting of domain-decomposed I/O; for single-file I/O, this is not necessary. This does not remove all references to FMS1 I/O from MOM6, only those in the I/O layer. Several minor changes are included to accommodate the change: * MOM restart I/O now always reports its MOM domain. Previously, the domian was omitted when PARALLEL_RESTARTFILES was false, in order to trick FMS into handling this as a single file. We now generate a new domain with an IO layout of [1,1] when single-file restarts are requested. * The interface acceleration (g') was incorrectly set to the layer grid (Nk) rather than the interface grid (Nk+1). This did not appear to change any answers, but when Vertical_coordinate.nc was moved to the netCDF layer, it detected this error. This is fixed in this patch. * Remove FMS1 calls from MOM_domains_infra * Add .nc extension to ALE Vertical_coordinate. The `Vertical_coordinate.nc` files has two points of creation, MOM_coord_initialization and MOM_ALE. Having moved the file from the infra to netCDF I/O layer, the .nc extension is no longer automatically applied. The extension was explicitly added to `Vertical_coordinate` in MOM_coord_initialization, but not to MOM_ALE. This patch adds the extension. Thanks to Kate Hedstrom for detecting this and Keith Lindsay for the proposed fix. * +Remove optional argument eta_to_m from find_eta Eliminate the unused optional argument eta_to_m from the two find_eta routines for simplicity and code clarity. These were used during the transition of the units of the interface height variables, but they are now using [Z ~> m] units everywhere, with the unscaling occurring via conversion factors in the register_diag calls. All answers are bitwise identical, but there is al optional argument that is removed from a public interface. * +Initialize thicknesses in height units Pass arguments in height units rather than thickness units to most of the routines that initialize thickness or temperatures and salinities. These routines are already undoing this scaling and working in height units, and it is not possible to convert thicknesses to thickness units in non-Boussinesq mode until the temperatures and salinities are also known. The routines whose argument units are altered include: - initialize_thickness_uniform - initialize_thickness_list - DOME_initialize_thickness - ISOMIP_initialize_thickness - benchmark_initialize_thickness - Neverworld_initialize_thickness - circle_obcs_initialize_thickness - lock_exchange_initialize_thickness - external_gwave_initialize_thickness - DOME2d_initialize_thickness - adjustment_initialize_thickness - sloshing_initialize_thickness - seamount_initialize_thickness - dumbbell_initialize_thickness - soliton_initialize_thickness - Phillips_initialize_thickness - Rossby_front_initialize_thickness - user_initialize_thickness - DOME2d_initialize_temperature_salinity - ISOMIP_initialize_temperature_salinity - adjustment_initialize_temperature_salinity - baroclinic_zone_init_temperature_salinity - sloshing_initialize_temperature_salinity - seamount_initialize_temperature_salinity - dumbbell_initialize_temperature_salinity - Rossby_front_initialize_temperature_salinity - SCM_CVMix_tests_TS_init - dense_water_initialize_TS - adjustEtaToFitBathymetry Similar changes were made internally to MOM_temp_salt_initialize_from_Z to defer the transition to working in thickness units, although the appropriate call to convert_thickness does still occur within MOM_temp_salt_initialize_from_Z and the units of its arguments are not changed. The routine convert thickness was modified to work with a new input depth space input thickness argument and return a thickness in thickness units, and it is now being called after all of the routines to initialize thicknesses and temperatures and salinities, except in the few cases where the thickness are being specified directly in mass-based thickness units, as might happen when they are read from an input file. The new option "mass_file" is now a recognized option for the THICKNESS_CONFIG runtime parameter, and this information is passed in the new mass_file argument to initialize_thickness_from_file. The description of the runtime parameter THICKNESS_IC_RESCALE was updated to reflect this change. The unused thickness (h) argument to soliton_initialize_velocity was eliminated. The unused thickness (h) argument to determine_temperature was eliminated, as was the unused optional h_massless argument to the same function. This commit also rearranges the calls to do adjustments to the thicknesses to account for the presence of an ice shelf or to iteratively apply the ALE remapping to occur before the velocities are initialized, so that there is a clearer separation of the phases of the initialization. Also added optional height_units argument to ALE_initThicknessToCoord to specify that the coordinate are to be returned in height_units. If it is omitted or false, the previous thickness units are returned, but when called from MOM_initialize_state the new argument is being used. The runtime parameter CONVERT_THICKNESS_UNITS is no longer meaningful, so it has been obsoleted. All answers are bitwise identical, but there are multiple changes to the arguments to publicly visible subroutines or their units, and there are changes to the contents of the MOM_parameter_doc files. * +Add the new overloaded interface dz_to_thickness Renamed convert_thickness from MOM_state_initialization to dz_to_thickness_tv in MOM_density_integrals, so that it can be called from other lower-level modules. This new version also takes the tv%p_surf field into account and it has an optional halo_size argument, analogous to that in the other routines in the MOM_density_integrals module. The dz_to_thickness interface is overloaded so that it can also be used directly with temperature, salinity, and the equation of state type if the thermo_var_ptrs is not available. There is also a new and separate variant of this routine, dz_to_thickness_simple, that can be used in pure layered mode when temperature and salinity are not state variables, or (more dangerously) if it is not clear whether or not there is an equation of state. This simpler version is being kept separate from the main overloaded interface because its use may need to be revisited later in some cases. All answers are bitwise identical, but there are two new public interfaces, dz_to_thickness and dz_to_thickness_simple. * (*)Improve non-Boussinesq initialization This commit includes three distinct sets of changes inside of MOM_state_initialization.F90 to better handle the initialization of non-Boussinesq models, none of which change any answers in Boussinesq models. These include: - Refactored trim_for_ice to have a separate, simpler form appropriate for use in non-Boussinesq mode. The units of the min_thickness argument to cut_off_column top were also changed to thickness units. - Initialize_sponges_file was refactored to work in depth-space variables before using dz_to_thickness to convert to thicknesses, but also to properly handle the case where the input file has a different number of vertical layers than the model is using, in which case the previous version could have had a segmentation fault. - Code in MOM_temp_salt_initialize_from_Z was reordered to more clearly group it into distinct phases. It also uses the new dz_to_thickness routine to convert input depths into thicknesses. All answers are bitwise identical in all Boussinesq test cases and all test cases in the MOM6-examples regression suite, but answers could be changed and improved in some non-Boussinesq cases. * (*)Use dz_to_thickness in 4 user modules Use dz_to_thickness to convert vertical distances to layer thicknesses in the sponge initialization routines in the DOME2d_initialization, ISOMIP_initialization, dumbbell_initialization and dense_water_initialization modules, and also in MOM_initialize_tracer_from_Z. For the user modules, the presence or absence of an equation of state is known and handled properly, but MOM_initialize_tracer_from_Z works with the generic tracer code and it it outside of the scope of MOM6 code to provide any information about the equation of state or the state variables that would be needed to initialize a non-Boussinesq model properly from a depth-space input file. For now we are doing the best we can, but this should be revisited. All examples in existing test cases are bitwise identical, but answers could change (and be improved) in any non-Boussinesq variants of the relevant test cases. * Update the Gitlab .testing modules for c5 In preparation for the migration to C5, this patch updates the modules required to run the .testing suite. * POSIX: generic wrappers for all setjmp.h symbols This patch extends the generic wrappers of sigsetjmp to all of the *jmp wrapper functions in The C standard allows these to be defined as macros, rather than explicit functions, which cannot be referenced by Fortran C bindings, so we cannot assume that these functions exist, even when using a compliant libc. As with sigsetjmp, these functions are now disabled on default, and raise a runtime error if called by the program. Realistically, they will only be defined by an autoconf-configured build. This is required for older Linux distributions where libc does not define longjmp. * Autoconf: External FMS build configuration This patch modifies the `ac/deps` Makefile used to build the FMS depedency. The autoconf compilation is now done entirely outside of the `ac/deps/fms/src` directory. This keeps the FMS checkout unchanged and allows us to better track any development changes in that library during development. The .testing/Makefile was also modified to use existing rules in deps/Makefile rather than duplicating them. Dependency of the m4 directory is also now more explicit (albeit still somewhat incomplete). * Autoconf: Explicit MOM_memory.h configuration MOM6 requires an explicit MOM_memory.h header to define its numerical field memory layout. Previously, autoconf provided a flag to configure this with `--enable-*`, but was prone to two issues: * The binary choice of symmetric/nonsymmetric prevented use of static headers. * It was an incorrect use of `--enable-*`, which is intended to enable additional internal features; it is not used to select a mode. To address these issues, we drop the flag and replace it with an AC_ARG_VAR variable, MOM_MEMORY, which is a path to the file. This variable will default to dynamic symmetric mode, config_src/memory/dynamic_symmetric/MOM_memory.h so there should be no change for existing users. To the best of my knowledge, no one used the `--enable-*` flag, nor was it used in any automated systems (outside of .testing), so there should be no issue with dropping it. .testing/Makefile was updated to use MOM_MEMORY. * Profiling: subparameter parser support The very crude MOM_input parser in the automatic profiler did not support subparameters (e.g. MLE% ... %MLE), which caused an error when trying to read the FMS clock output. This patch adds the support, or at least enough support to avoid errors. * +*Redefine GV%Angstrom_H in non-Boussinesq mode Redefined GV%Angstrom_H in non-Boussinesq mode so that it is equal to GV%H_to_Z*GV%Angstrom_Z, just as it is in Boussinesq mode. This will change answers (slightly) in all cases with BOUSSINESQ = False. In addition, this commit adds the elements semi_Boussinesq, dZ_subroundoff, m2_s_to_HZ_T, HZ_T_to_m2_s and HZ_T_to_MKS to the verticalGrid_type. The first 3 new elements are used in rescaling vertical viscosities and diffusivities. The last two elements are set using the new runtime parameters SEMI_BOUSSINESQ and RHO_KV_CONVERT, which are only used or logged when BOUSSINESQ = False. All answers and output are identical in Boussinesq cases, but answers change and there are new runtime parameters in non-Boussinesq cases. * +Set_interp_answer_date and REGRIDDING_ANSWER_DATE Add the ability to set the answer date for the regridding code, including the addition of the new subroutine set_interp_answer_date and the new runtime parameter REGRIDDING_ANSWER_DATE to specify the code vintage to use with state- dependent vertical coordinates. There is also new optional argument to set_regrid_params. By default, all answers are bitwise identical, but there are new or modified public interfaces and there is a new entry in some MOM_parameter_doc files. * *+Revise non-Boussinesq find_coupling_coef calcs Restructure one of the find_coupling_coef calculations to draw out the stress-magnitude terms, in preparation for future steps to reduce the dependency on the Boussinesq reference density. Using a value of VERT_FRICTION_ANSWER_DATE that is below 20230601 recovers the previous answers with non-Boussinesq test cases, but this is irrelevant for Boussinesq test cases. This updated code is mathematically equivalent to the previous expressions but it does change answers at roundoff in non-Boussinesq cases for recent answer dates. There are modifications to some comments in MOM_parameter_doc files. * +Code to calculate layer averaged specific volumes Add routines to calculate and store the layer-averaged specific volume, along with code to do the unit testing of this new capability. The new public interfaces include avg_specific_vol, average_specific_vol, avg_spec_vol_Wright, avg_spec_vol_Wright_full, avg_spec_vol_Wright_red and avg_spec_vol_linear. There is also a new optional argument to test_EOS_consistency to control whether these new capabilties are tested for a particular equation of state. All answers are bitwise identical, and the new capabilities pass the unit testing for self consistency. * +Add thickness_to_dz and calc_derived_thermo Added the new overloaded interface thickness_to_dz to convert the layer thicknesses in thickness units [H ~> m or kg m-2] into vertical distances in [Z ~> m], with variants that set full 3-d arrays or an i-/k- slice. Also added a field (SpV_avg) for the layer-averaged specific volume to the thermo_vars_ptr type and the new subroutine calc_derived_thermo to set it. This new subroutine is being called after halo updates to the temperatures and salinities. The new runtime parameter SEMI_BOUSSINESQ was added to determine whether tv%SpV_avg is allocated and used; it is stored in GV%semi_Boussinesq. Also added the new element GV%dZ_subroundoff to the verticalGrid_type as a counterpart to GV%H_subroundoff but in height units. All answers are bitwise identical, but there is a new runtime parameter in some MOM_parameter_doc files, new elements in a transparent type and a new public interface. * wave structure computation into wave_speeds wave_speeds now computes the wave structures (eigenvectors) for each mode speed (eigenvalue) similarly to the wave_speed (singular) function. This is a replacement for the MOM_wave_structure function, which could be removed in a subsequent PR. Additional arrays for mode strucures and integral quantities are passed as output hence this is a breaking change for the call to wave_speeds. However it is only called once in diabatic_driver and is used exclusively for internal tides ray tracing. The dimensional solutions for the wave structures are now computed inside MOM_internal_tides, and new diagnostics are added. An out-of-bounds bug is also corrected for the computation of an averaged coriolis parameter. * remove wave_structure broken code * Autoconf: Better Unicode Python support in makedep The `open()` commands in `makedep` for reading Fortran source now includes an `errors=` argument for catching bytes outside of the file character set. Unknown characters are replaced with the "unknown" character (usually �) rather than raising an error. This avoids problems with Unicode characters and older Pythons which do not support them, as well as characters from legacy encodings which can cause errors in Unicode. Substitution does not break any behavior, since Unicode is only permitted inside of comment blocks and strings. This fixes several errors which were silent in `.testing` but were observed by some users which using autoconf to build their own executables. * Autoconf: Fix Python test and allow configuration The AC_PATH_PROGS macros used in Python testing were incorrectly using AC_MSG_ERROR in places where a missing value for PYTHON should be if the executable was not found. It also did not permit for a configurable PYTHON variable, since the autodetect was always run, even if PYTHON were set. This has been updated so that Python autodetection only runs if PYTHON is unset. It also correctly reports a failed configuration if PYTHON is not found. (It does not, however, test of PYTHON is actually a Python interpreter, but we can deal with that at a later date.) * Fix PGI runtime issue with class(*) - Some tests such as global_ALE_z crash under PGI (ncrc4.pgi20 or ncrc5.pgi227) with FATAL from PE 27: unsupported attribute type: get_variable_attribute_0d: file:INPUT/tideamp.nc- variable:GRID_X_T attribute: axis - PGI in general has issues with class(*) construct and in this case cannot recognize the axis argument to be a string. - This mod helps PGI recognize that the argument is a string. * Use fileset rather than threading for decompositon MOM IO was using the `threading` flag rather than `fileset` to determine whether a file should be forced as single file rather than domain-decomposed. This patch applies the correct flag. * FMS2 interpolation ID replaced with derived type All instances of an FMS ID to the internal interpolation content is replaced with a derived type containing additional metadata recording the field's origin filename and fieldname. This additional information is required in order to replicate the axis data from the field, which is no longer provided by FMS2. The abstraction of this type also allows us to either extend it or redefine it in other frameworks as needed in the future. This primarily affects the usage of the following functions: - init_external_field - time_interp_external - horiz_interp_and_extrap_tracer The following solvers are updated: - MOM_open_boundary - MOM_ice_shelf - MOM_oda_driver - MOM_MEKE - MOM_ALE_sponge - MOM_diabatic_aux Of these, OBC was the most significant. The integer handle (fid) was previously used to determine if each segment field was constant or (if negative) read from a file. After being replaced by the derived type, a new flag was added to make this determination. All of the coupled drivers have been modified, since they support time interpolation of T and S fields. - FMS - MCT - NUOPC The NUOPC driver also includes modifications to its CFC11 and CFC12 fields. Changes to the MOM CFC modules replaces an `id == -1`-like test, which is not used by the derived type. This check has been removed, and we now solely rely on the `present(cfc_handle)` test. While this could change behavior, there does not seem to be any scenario where init_external_field would return -1 but would be passed to the function. (But I may eat these words.) * FMS2: Remove MPP-based axis data access With removal of axis-based operations in FMS2 I/O, this patch removes references to these calls and replaces them with MOM `axes_info` types. References to FMS1 read into an `axistype`, but the contents are transferred to an `axis_info`. FMS2 directly populates the `axis_info` content. The `get_external_field_info` calls are modified to return `axis_info` rather than `axistype`. The redundant `get_axis_data` function is also removed from `MOM_interp_infra`, since `get_axis_info` provides an equivalent operation. Generally speaking, this is not an improvement of the codebase. The FMS1 layer does a redundant copy of data from `axistype` to `axis_info`. The FMS2 layer is significantly worse, and re-opens the file to read the axis data for each field! But if the intention is to leverage the existing API, then I don't think we have any choice at the moment. Assuming this is a relatively infrequent operation, this should not cause any measureable issues, but it needs to be watched carefully. * FMS2: Update time_interp_external functions This patch shifts all remaining time_interp_external functions from time_interp_external to equivalent ones in time_interp_external2. Internally, time-interpolated fields are initialized with `ongrid` set to `.true.`, and such fields are assumed to be on-grid. This seems to hold for all existing instances of `time_interp_external`, but needs to be monitored in the future somehow. * FMS2: Case-insensitive init_external_field The FMS1 implementation of init_external_field is case-insensitive, but the FMS2 implementation is case-sensitive, which can cause errors in older established input files. This patch sweeps through the fields of the input files and checks for a case-insensitive match (using lowercase()). This requires an additional open/close of the file. * Implementation of ZB sheme * Filters for ZB. Regression changed (FGR changed to amplitude) * Rotate test is passed. Regression changed (order of operatrions) * ZB submitted via PR * ZB: Response to the code review * Update icebergs source path in nolibs build The icebergs project now includes drivers and tests which can interfere with the coupled nolibs build, so we only pass its src directory to mkmf. * +Make units argument mandatory for get_param_real This commit includes changes to the get_param_real and log_param_real interfaces to make the units arguments mandatory. It also adds an optional unscale argument to the log_param_real interfaces. Without other changes in the previous commits, it will cause the MOM6 code to fail to compile. However, by itself this commit does not change any answers or output. * github workflows: update to use actions/checkout@v3 - Update actions/checkout from v2 to v3 (suggested at https://github.com/NCAR/MOM6/pull/231#issuecomment-1347224581 thanks to @jedwards4b) * FMS2: Safe inspection of unlimited dim name The FMS2 function `get_unlimited_dimension_name` raises a netCDF error if no unlimited dimension is found. This is problematic for legacy or externally created input files which may have not identifed their time axis as unlimited. This patch adds a new function, `find_unlimited_dimension_name` which mirrors the FMS2 function but returns an empty string if none are found. This is an internal function, not intended for use outside of the module. * +Refactor internal_tides interface Refactors the internal tide code in MOM_internal_tides and MOM_diabatic_driver to consolidate it in the MOM_internal_tides module and allow the control structure for that module to be made opaque. This includes moving the internal wave speed diagnostics and the call to wave_speeds or other code setting the internal wave speeds into propagate_int_tide. The get_param calls for INTERNAL_WAVE_CG1_THRESH and UNIFORM_TEST_CG were moved from the diabatic module to the MOM_internal_tides module. The wave_speed_CS and uniform_test_cg were removed from diabatic_CS and added to int_tide_CS. The Nb argument to propagate_int_tide has been made intent inout, as it is now usually set via the call to wave_speeds in that routine, but for certain tests it could use the value passed in from diabatic_driver. All answers are bitwise identical, but there are changes to public interfaces and types, and the order of some entries in the MOM_parameter_doc files and the available_diags files is changed for some cases. * +Add fluxes%tau_mag and forces%tau_mag Add new allocatable tau_mag arrays to the forcing and mech_forcing types to hold the magnitude of the wind stresses including gustiness contributions. There is also a new tau_mag diagnostic. This same information in tau_mag is being transformed into ustar, but these changes avoid division by the Boussinesq reference density (GV%Rho0), and allow for a more accurate calculation of derived fields when in non-Boussinesq mode, without having to multiply and divide by GV%Rho0. There is also a new optional tau_mag argument to extract_IOB_stresses to support these changes. These new arrays are not being used yet in the MOM6 solutions, but they are being allocated and populated in the routines that set the ustar fields, and they have been tested in changes to the modules that use ustar that will come in a subsequent commit. This commit also adds the new RLZ_T2_to_Pa element to the unit_scale_type to undo the scaling of wind stresses and it makes use of it in some of the new code. All answers are bitwise identical, but there are new arrays or elements in three transparent public types. * *+Fix problems in mixedlayer_restrat_Bodner Fixed several problems with the recently added Bodner mixed layer restratification parameterization code. - Corrected the dimensional rescaling in the expressions for psi_mag by adding a missing factor of US%L_to_Z. - A logical branch was added based on the correct mask for land or OBC points to avoid potentially ill-defined calculations of the magnitude of the Bodner parameterization streamfunction, some which were leading to NaNs. - Set a tiny but nonzero default value for MIN_WSTAR2 to avoid NaNs in some calculations of the streamfunction magnitude. - Revised the expression for dd within the mu function in a mathematically equivalent way to avoid any possibility of taking a fractional exponential power of a tiny negative number due to truncation errors, which was leading to NaNs in some cases while developing and debugging the other changes that are not included in this commit. This does not appear to change any answers in the existing test cases, perhaps because the mixed layer restratification "tail" is not being activated by setting TAIL_DH to be larger than 0. - Corrected or added variable units in comments in the mixedlayer_restrat control structure. These could change answers (and avoid NaNs) in some cases with USE_BODNER23=True, MLE_TAIL_DH > 0 or MLE%TAIL_DH > 0, and there will be changes to the MOM_parameter_doc files for some cases, but given how recently this code was added, it is expected that all answers are bitwise identical in the existing test cases. * FMS2: New interface to set/nullify_domain This patch adds wrappers to the set_domain and nullify_domain functions used in FMS1 for internal FMS IO operations. These are not used in FMS2, so the wrapper functions are empty. This is required to eliminate FMS1 IO dependencies in SIS2. * *Correct nuopc_cap tau_mag bug Correct a recently added bug in the expression for tau_mag in the nuopc_cap version of convert_IOB_to_forces, where CS%gust(i,j) was used in place of CS%gust_const, even though the 2-d array was not being set. This commit changes answers in some recent versions of the code back to what they had been previously, and it addresses concerns that had been raised with the first version of gfdl-candidate-2023-07-03 and its PR to the main version of MOM6. * Fms2 io read3d slice (#399) * Restore functionality for reading slices from 3d volumes in MOM_io - The recent MOM_io modifications in support of FMS2_io accidentally removed support for reading on-grid data (same horizontal grid as model) k-slices. This is needed in some configurations in the model state initialization. * Add FMS1 interfaces * Additional patches to enable reading ongrid state initialization data - read local 3d volume rather than attempting to slice ongrid data vertically. - Related bugfixes in MOM_io * Update MOM_variables.F90 --------- Co-authored-by: Alistair Adcroft Co-authored-by: Abigail Bodner Co-authored-by: Marshall Ward Co-authored-by: Robert Hallberg Co-authored-by: Marshall Ward Co-authored-by: Raphael Dussin Co-authored-by: Niki Zadeh Co-authored-by: Pavel Perezhogin Co-authored-by: Matthew Harrison Co-authored-by: Matthew Thompson --- .github/workflows/coupled-api.yml | 2 +- .github/workflows/coverage.yml | 2 +- .github/workflows/documentation-and-style.yml | 2 +- .github/workflows/expression.yml | 2 +- .github/workflows/macos-regression.yml | 2 +- .github/workflows/macos-stencil.yml | 2 +- .github/workflows/other.yml | 2 +- .github/workflows/perfmon.yml | 2 +- .github/workflows/regression.yml | 2 +- .github/workflows/stencil.yml | 2 +- .gitlab-ci.yml | 86 +- .gitlab/pipeline-ci-tool.sh | 14 +- .testing/Makefile | 41 +- .testing/tc2.a/MOM_tc_variant | 6 + .testing/tools/parse_fms_clocks.py | 54 +- ac/configure.ac | 87 +- ac/deps/Makefile | 25 +- ac/makedep | 5 +- .../FMS_cap/MOM_surface_forcing_gfdl.F90 | 91 +- .../mct_cap/mom_surface_forcing_mct.F90 | 19 +- config_src/drivers/nuopc_cap/mom_cap.F90 | 4 +- .../nuopc_cap/mom_surface_forcing_nuopc.F90 | 19 +- .../solo_driver/MESO_surface_forcing.F90 | 2 +- .../solo_driver/MOM_surface_forcing.F90 | 139 +- .../solo_driver/user_surface_forcing.F90 | 9 +- config_src/infra/FMS1/MOM_coms_infra.F90 | 24 +- config_src/infra/FMS1/MOM_domain_infra.F90 | 31 +- config_src/infra/FMS1/MOM_interp_infra.F90 | 96 +- config_src/infra/FMS1/MOM_io_infra.F90 | 41 +- config_src/infra/FMS2/MOM_coms_infra.F90 | 23 +- config_src/infra/FMS2/MOM_domain_infra.F90 | 34 +- config_src/infra/FMS2/MOM_interp_infra.F90 | 157 +- config_src/infra/FMS2/MOM_io_infra.F90 | 1067 ++++++------ src/ALE/MOM_ALE.F90 | 14 +- src/ALE/MOM_hybgen_regrid.F90 | 2 +- src/ALE/MOM_regridding.F90 | 24 +- src/ALE/regrid_interp.F90 | 17 +- src/core/MOM.F90 | 145 +- src/core/MOM_PressureForce_FV.F90 | 2 +- src/core/MOM_barotropic.F90 | 30 +- src/core/MOM_checksum_packages.F90 | 6 +- src/core/MOM_density_integrals.F90 | 34 +- src/core/MOM_dynamics_split_RK2.F90 | 54 +- src/core/MOM_forcing_type.F90 | 70 +- src/core/MOM_interface_heights.F90 | 357 +++- src/core/MOM_open_boundary.F90 | 31 +- src/core/MOM_unit_tests.F90 | 6 + src/core/MOM_variables.F90 | 7 +- src/core/MOM_verticalGrid.F90 | 71 +- src/diagnostics/MOM_diagnostics.F90 | 11 +- src/diagnostics/MOM_obsolete_params.F90 | 1 + src/diagnostics/MOM_wave_speed.F90 | 257 ++- src/diagnostics/MOM_wave_structure.F90 | 793 --------- src/equation_of_state/MOM_EOS.F90 | 1442 ++++++++++++++--- src/equation_of_state/MOM_EOS_Jackett06.F90 | 590 +++++++ src/equation_of_state/MOM_EOS_NEMO.F90 | 432 ----- src/equation_of_state/MOM_EOS_Roquet_SpV.F90 | 813 ++++++++++ src/equation_of_state/MOM_EOS_Roquet_rho.F90 | 633 ++++++++ src/equation_of_state/MOM_EOS_TEOS10.F90 | 26 +- src/equation_of_state/MOM_EOS_UNESCO.F90 | 729 ++++++--- src/equation_of_state/MOM_EOS_Wright.F90 | 345 +++- src/equation_of_state/MOM_EOS_Wright_full.F90 | 1033 ++++++++++++ src/equation_of_state/MOM_EOS_Wright_red.F90 | 1033 ++++++++++++ src/equation_of_state/MOM_EOS_linear.F90 | 54 +- src/equation_of_state/MOM_TFreeze.F90 | 97 +- .../MOM_temperature_convert.F90 | 166 ++ src/equation_of_state/_Equation_of_State.dox | 86 +- src/framework/MOM_file_parser.F90 | 8 +- src/framework/MOM_horizontal_regridding.F90 | 41 +- src/framework/MOM_interpolate.F90 | 27 +- src/framework/MOM_io.F90 | 181 ++- src/framework/MOM_io_file.F90 | 28 +- src/framework/MOM_restart.F90 | 4 +- src/framework/MOM_unit_scaling.F90 | 42 +- src/framework/posix.F90 | 51 +- src/framework/posix.h | 16 +- src/ice_shelf/MOM_ice_shelf.F90 | 51 +- src/ice_shelf/MOM_ice_shelf_dynamics.F90 | 19 -

Jackett et al. (2006) provide an approximation for the in situ density as a function of +!! potential temperature, salinity, and pressure. This 25 term equation of state is +!! frequently used in Hycom for a potential density, at which point it only has 17 terms +!! and so is commonly called the "17-term equation of state" there. Here the full expressions +!! for the in situ densities are used. +!! +!! The functional form of this equation of state includes terms proportional to salinity to the +!! 3/2 power. This introduces a singularity in the second derivative of density with salinity +!! at a salinity of 0, but this has been addressed here by setting a floor of 1e-8 PSU on the +!! salinity that is used in the denominator of these second derivative expressions. This value +!! was chosen to imply a contribution that is smaller than numerical roundoff in the expression for +!! density, which is the field for which the Jackett et al. equation of state was originally derived. +!! +!! \subsection section_EOS_Jackett06_references References +!! +!!

The UNESCO (1981) equation of state is an internationally defined standard fit valid over the +!! range of pressures up to 10000 dbar, temperatures between the freezing point and 40 degC, and +!! salinities between 0 and 42 PSU. Unfortunately, these expressions used in situ temperatures, +!! whereas ocean models (including MOM6) effectively use potential temperatures as their state +!! variables. To avoid needing multiple conversions, Jackett and McDougall (1995) refit the +!! UNESCO equation of state to take potential temperature as a state variable, over the same +!! valid range and functional form as the original UNESCO expressions. It is this refit from +!! Jackett and McDougall (1995) that is coded up in this module. +!! +!! The functional form of the equation of state includes terms proportional to salinity to the +!! 3/2 power. This introduces a singularity in the second derivative of density with salinity +!! at a salinity of 0, but this has been addressed here by setting a floor of 1e-8 PSU on the +!! salinity that is used in the denominator of these second derivative expressions. This value +!! was chosen to imply a contribution that is smaller than numerical roundoff in the expression +!! for density, which is the field for which the UNESCO equation of state was originally derived. +!! +!!

Their defaults are set to RHO_0 to reproduce previous answers. Also added tau_mag arguments to 2 calls to allocate_forcing_type() and 4 calls to allocate_mech_forcing() in the FMS_cap and solo_driver code. There are new rho_restore elements in the FMS and solo_driver versions of surface_forcing_CS and in MESO_surface_forcing_CS and user_surface_forcing_CS.

Several other minor issues (which might not change any answers in production runs) were also fixed. The changes with this commit include: - When in non-Boussinesq mode, the mixed layer buoyancy gradients are determined from the average specific volume referenced to the surface pressure, rather than from the average potential density. - Use find_ustar to set the friction velocities in the appropriate units in the various mixed_layer_restrat routines. - A logical branch was added based on the correct mask for land or OBC points to avoid potentially ill-defined calculations of the magnitude of the Bodner parameterization streamfunction, some which were leading to NaNs. - Set a tiny but nonzero default value for MIN_WSTAR2 to avoid NaNs in some calculations of the streamfunction magnitude. - Within the function mu, the expression for dd was revised in a mathematically equivalent way to avoid any possibility of taking a fractional exponential power of a tiny negative number due to truncation errors, which was leading to NaNs in some cases while developing and debugging the other changes in this commit. This does not appear to change any answers in the existing test cases, perhaps because the mixed layer restratification "tail" is not being activated by setting TAIL_DH to be larger than 0. - The addition of code to both mixedlayer_restrat_Bodner and mixedlayer_restrat_OM4 to determine the mixed layer thickness from its vertical extent when in non-Boussinesq mode. This commit includes changes to the units of the Kv_restrat, ustar_min and wpup_filtered elements in the mixedlayer_restrat_CS type and the units of four arguments to the private function growth_time. CS%wpup_filtered also appears in the restart files generated with some mixed layer restratification settings, and it is rescaled to units of vertical distance or mass per unit area in the restart files depending on whether the model is Boussinesq. There are 17 new or renamed internal variables, while the units of 21 internal variables were changed. 19 rescaling factors were cancelled out or replaced. There are also comments where variable units were corrected or added. The rescaling of several chksum calls for thicknesses was modified to GV%H_to_mks to avoid any dependence on RHO_0 when non-Boussinesq. No public interfaces are changed. All answers are bitwise identical in Boussinesq mode (at least when TAIL_DH=0.), but solutions will change in non-Boussinesq mode when mixed layer restratification is enabled, including changes to the units of a variable in the restart files. --- .../lateral/MOM_mixed_layer_restrat.F90 | 532 ++++++++++++------ 1 file changed, 345 insertions(+), 187 deletions(-) diff --git a/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 b/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 index 9cf79b07ce..444ef8f064 100644 --- a/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 +++ b/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 @@ -19,7 +19,7 @@ module MOM_mixed_layer_restrat use MOM_unit_scaling, only : unit_scale_type use MOM_variables, only : thermo_var_ptrs use MOM_verticalGrid, only : verticalGrid_type, get_thickness_units -use MOM_EOS, only : calculate_density, EOS_domain +use MOM_EOS, only : calculate_density, calculate_spec_vol, EOS_domain implicit none ; private @@ -86,15 +86,17 @@ module MOM_mixed_layer_restrat type(diag_ctrl), pointer :: diag !< A structure that is used to regulate the !! timing of diagnostic output. - logical :: use_stanley_ml !< If true, use the Stanley parameterization of SGS T variance - real :: ustar_min !< A minimum value of ustar to avoid numerical problems [Z T-1 ~> m s-1] + logical :: use_Stanley_ML !< If true, use the Stanley parameterization of SGS T variance + real :: ustar_min !< A minimum value of ustar in thickness units to avoid numerical + !! problems [H T-1 ~> m s-1 or kg m-2 s-1] real :: Kv_restrat !< A viscosity that sets a floor on the momentum mixing rate - !! during restratification [Z2 T-1 ~> m2 s-1] + !! during restratification, rescaled into thickness-based + !! units [H2 T-1 ~> m2 s-1 or kg2 m-4 s-1] real, dimension(:,:), allocatable :: & MLD_filtered, & !< Time-filtered MLD [H ~> m or kg m-2] MLD_filtered_slow, & !< Slower time-filtered MLD [H ~> m or kg m-2] - wpup_filtered !< Time-filtered vertical momentum flux [Z2 T-2 ~> m2 s-2] + wpup_filtered !< Time-filtered vertical momentum flux [H L T-2 ~> m2 s-2 or kg m-1 s-2] !>@{ !!

This is done by using calls to calculate_density and calculate_specific_vol_derivs to calculate the thermal expansion and haline contraction coefficients, and by using thickness_to_dz to convert layer thicknesses to vertical distances. A large part of the changes to the kappa_shear code involved refactoring it to differentiate between thicknesses and geometric heights by working internally with dynamic viscosities and diffusivities in non-Boussinesq mode, and to keep thicknesses in thickness units rather than converting them to distances in height units. The internal variable dz was renamed to h_lay in Calculate_kappa_shear and Calc_kappa_shear_vertex for greater clarity. The scaling factor for dz_massless is now set to (US%Z_to_m*GV%m_to_H) in Calculate_kappa_shear to reduce the dependency on the Boussinesq reference density; this does not impact answers if RHO_0 = RHO_KV_CONVERT. The internal changes related to this are extensive. This commit includes changing the units of 63 internal variables, and the addition or renaming of 17 internal variables. There are 2 new arguments to find_kappa_tke (one is necessary to differentiate thicknesses from vertical distances and while the other is used to preserve Boussinesq-mode answers), and 1 new argument to kappa_shear_column plus the renaming of another. The units of 13 internal subroutine arguments and 3 elements of the Kappa_shear_CS type change. A total of 6 thickness unit conversion factors were eliminated with these changes. The answers will change in non-Boussinesq mode when the Jackson et al. shear mixing parameterization is in use, but they are bitwise identical in all Boussinesq test cases.

The new module includes both online spherical harmonics method and scalar approximation. Read-in method (TIDAL_SAL_FROM_FILE) is kept in the tidal forcing module as it is specific to tides. For the iterative method (USE_PREV_TIDES), the updating part that is tied to the scalar approximation is moved to the new SAL model, while the read-in part remains in the tidal_forcing module. The tidal forcing module now only contains calculations independent from the ocean's state and the only input variables is the current time. * A new parameter CALCULATE_SAL is added, which controls SAL calculation in PressureForce independent of whether tides is on or not. The default of CALCULATE_SAL is TIDES to avoid making changes in old MOM_input. * For the unplit mode, runtime parameters calculate_SAL and use_tides are moved from init subroutines to control structures. This allows safe deallocations of the corresponding module CSs. * A new control structure for the SAL module is used by the dynamical cores and pressure force modules. * For SAL related parameters, their names still incorrectly contain TIDE or TIDAL. This will be addressed in the following commits. * A new diagnostic is added in PressureForce to output calculated SAL fields. Note that the 'e_tidal' diagnostic is unchanged and still includes SAL field for backward compatibility. * Subroutine tidal_forcing_sensitivity, which is used by the barotropic solver to take into account the scalar approximation, is renamed to scalar_SAL_sensitivity. * Documentations are updated for the cited papers. --- src/core/MOM_PressureForce.F90 | 10 +- src/core/MOM_PressureForce_FV.F90 | 81 ++++-- src/core/MOM_PressureForce_Montgomery.F90 | 70 +++-- src/core/MOM_barotropic.F90 | 34 ++- src/core/MOM_dynamics_split_RK2.F90 | 13 +- src/core/MOM_dynamics_unsplit.F90 | 20 +- src/core/MOM_dynamics_unsplit_RK2.F90 | 20 +- .../lateral/MOM_load_love_numbers.F90 | 24 +- .../lateral/MOM_self_attr_load.F90 | 271 ++++++++++++++++++ .../lateral/MOM_spherical_harmonics.F90 | 16 +- .../lateral/MOM_tidal_forcing.F90 | 215 ++------------ 11 files changed, 491 insertions(+), 283 deletions(-) create mode 100644 src/parameterizations/lateral/MOM_self_attr_load.F90 diff --git a/src/core/MOM_PressureForce.F90 b/src/core/MOM_PressureForce.F90 index 844d9db4bc..ad76a9a9f5 100644 --- a/src/core/MOM_PressureForce.F90 +++ b/src/core/MOM_PressureForce.F90 @@ -13,6 +13,7 @@ module MOM_PressureForce use MOM_PressureForce_Mont, only : PressureForce_Mont_Bouss, PressureForce_Mont_nonBouss use MOM_PressureForce_Mont, only : PressureForce_Mont_init use MOM_PressureForce_Mont, only : PressureForce_Mont_CS +use MOM_self_attr_load, only : SAL_CS use MOM_tidal_forcing, only : tidal_forcing_CS use MOM_unit_scaling, only : unit_scale_type use MOM_variables, only : thermo_var_ptrs @@ -80,7 +81,7 @@ subroutine PressureForce(h, tv, PFu, PFv, G, GV, US, CS, ALE_CSp, p_atm, pbce, e end subroutine Pressureforce !> Initialize the pressure force control structure -subroutine PressureForce_init(Time, G, GV, US, param_file, diag, CS, tides_CSp) +subroutine PressureForce_init(Time, G, GV, US, param_file, diag, CS, SAL_CSp, tides_CSp) type(time_type), target, intent(in) :: Time !< Current model time type(ocean_grid_type), intent(in) :: G !< Ocean grid structure type(verticalGrid_type), intent(in) :: GV !< Vertical grid structure @@ -88,7 +89,8 @@ subroutine PressureForce_init(Time, G, GV, US, param_file, diag, CS, tides_CSp) type(param_file_type), intent(in) :: param_file !< Parameter file handles type(diag_ctrl), target, intent(inout) :: diag !< Diagnostics control structure type(PressureForce_CS), intent(inout) :: CS !< Pressure force control structure - type(tidal_forcing_CS), intent(inout), optional :: tides_CSp !< Tide control structure + type(SAL_CS), intent(in), optional :: SAL_CSp !< SAL control structure + type(tidal_forcing_CS), intent(in), optional :: tides_CSp !< Tide control structure #include "version_variable.h" character(len=40) :: mdl = "MOM_PressureForce" !

This commit decompose the two fields for better diagnostics. This also makes answers using USE_PREV_TIDES is not changed if only one tidal constituent is used. New diagnostics ('e_tidal_eq' and 'e_tidal_sal') are added in pressure force modules for the decomposed fields. Note that 'e_tidal' still includes all tidal fields + SAL fields to be backward compatible. --- src/core/MOM_PressureForce_FV.F90 | 54 ++++++++++++------- src/core/MOM_PressureForce_Montgomery.F90 | 50 ++++++++++------- .../lateral/MOM_tidal_forcing.F90 | 36 +++++++------ 3 files changed, 86 insertions(+), 54 deletions(-) diff --git a/src/core/MOM_PressureForce_FV.F90 b/src/core/MOM_PressureForce_FV.F90 index 27a4e3ae5a..4dc354b01c 100644 --- a/src/core/MOM_PressureForce_FV.F90 +++ b/src/core/MOM_PressureForce_FV.F90 @@ -62,7 +62,9 @@ module MOM_PressureForce_FV !!

The answer change is due to an reorder of summations of the SAL and tidal forcing terms. * The new version flag only applies to the analytical pressure force in Boussinesq mode, which is virtually the only configuration widely used and included in the test suite. * For Montgomery pressure and non-Boussinesq mode, the code is refactored in a more readable way. --- src/core/MOM_PressureForce_FV.F90 | 55 ++++++++---- src/core/MOM_PressureForce_Montgomery.F90 | 49 ++++++----- .../lateral/MOM_tidal_forcing.F90 | 83 +++++++++++++++++++ 3 files changed, 149 insertions(+), 38 deletions(-) diff --git a/src/core/MOM_PressureForce_FV.F90 b/src/core/MOM_PressureForce_FV.F90 index 25301ae31d..4314c1f7df 100644 --- a/src/core/MOM_PressureForce_FV.F90 +++ b/src/core/MOM_PressureForce_FV.F90 @@ -11,6 +11,7 @@ module MOM_PressureForce_FV use MOM_PressureForce_Mont, only : set_pbce_Bouss, set_pbce_nonBouss use MOM_self_attr_load, only : calc_SAL, SAL_CS use MOM_tidal_forcing, only : calc_tidal_forcing, tidal_forcing_CS +use MOM_tidal_forcing, only : calc_tidal_forcing_legacy use MOM_unit_scaling, only : unit_scale_type use MOM_variables, only : thermo_var_ptrs use MOM_verticalGrid, only : verticalGrid_type @@ -62,6 +63,7 @@ module MOM_PressureForce_FV !!

The subroutine calls from this module have already been revised, so only this file needs to be updated. The specific changes include: - Rescaled the nominal mixed layer depth variables HFREEZE, HMIX_SFC_PROP and HMIX_UV_SFC_PROP for determining surface properties to eliminate unit conversion factors during the run. This changes the units of 3 elements of the MOM_control_struct and one internal variable and adds 3 new internal variables. - Call calc_derived_thermo to update SpV_avg at the start of step_MOM if the internal ocean state depends on the surface pressure and that surface pressure has been passed in from the driver. There are 3 new internal variables and in some cases a new blocking halo update to enable these changes. All Boussinesq solutions are bitwise identical with this commit. It changes answers in some non-Boussinesq fully coupled or ice-ocean configurations. Other non-Boussinesq mode cases are mathematically equivalent in the case where RHO_0 = RHO_KV_CONVERT and bitwise identical if RHO_KV_CONVERT is an integer power of 2. This commit corrects issues with reproducability across restarts in the non-Boussinesq cases where the answer changes. --- src/core/MOM.F90 | 87 ++++++++++++++++++++++++++++++++++-------------- 1 file changed, 62 insertions(+), 25 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index c9b8ea42c0..e59c9ac60a 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -337,14 +337,14 @@ module MOM !

('Modified' here is not used in the same sense as 'modified 2D Leith'; it just means that the biharmonic coefficient is modified to account for enstrophy backscatter.) Variables are often named 'leithy' to refer to Leith+E. The parameterization is controlled by three main entries in user_nl_mom: 1. USE_LEITHY = True 2. LEITH_CK = 1.0 3. LEITH_BI_CONST = 8.0 To use Leith+E you should have LAPLACIAN=True and BIHARMONIC=True. (It doesn't hurt to be explicit and also set LEITH_AH=False, along with any other viscous closures, but this is not required. If USE_LEITHY=True it will not use any of the other schemes. It does use the background value of the biharmonic coefficient as a minimum, but ignores the background harmonic value.) LEITH_CK is the fraction of energy dissipated by the biharmonic term that gets backscattered by the harmonic term (it's a target; the backscatter rate is not exact.) Recommended values between 0 and 1. LEITH_BI_CONST is Upsilon^6 where Upsilon is the ratio between the grid scale and the dissipation scale for enstrophy. Values should be greater than or equal to 1; 8 is a good place to start. The code is sensitive to the background value of Ah; specifically, if Ah is too large, the code is unstable. This is because the backscatter coefficient is proportional to Ah, and if Ah is large then you get large backscatter. If your code is unstable, consider reducing, e.g., `AH_VEL_SCALE`. * Background Ah This commit updates the code so that it uses the background Ah as a minimum. Previously, if `SMAGORINSKY_AH = True`, Leith+E would use the Smag value of Ah as the minimum, which is incorrect. * Improve logging Removed `do_not_log` condition on `USE_LEITHY` * Fix Leithy Logic Added one line to fix the fact that the code would only work as intended if either (i) writing out Ah_h, or (ii) in debug mode.

This change involves changes to the units of arguments to update_offline_from_files and ALE_offline_inputs and to two elements of offline_transport_CS. It also includes a new thermo_vary_type argument to offline_diabatic_ale, as well as a call to thickness_to_dz in that same routine to set the values of the newly added 3-d array of the vertical distances across layers and a change in name and units of the inverse thickness variable used to find the fluxes. All answers are bitwise identical in Boussinesq mode, but in offline tracer calculations in non-Boussinesq mode they will change to become independent of the Boussinesq reference density. --- src/ALE/MOM_ALE.F90 | 5 +++-- src/core/MOM.F90 | 2 +- src/tracer/MOM_offline_aux.F90 | 5 +++-- src/tracer/MOM_offline_main.F90 | 24 +++++++++++++++--------- 4 files changed, 22 insertions(+), 14 deletions(-) diff --git a/src/ALE/MOM_ALE.F90 b/src/ALE/MOM_ALE.F90 index b8f60b2830..4d7445093a 100644 --- a/src/ALE/MOM_ALE.F90 +++ b/src/ALE/MOM_ALE.F90 @@ -504,13 +504,14 @@ subroutine ALE_offline_inputs(CS, G, GV, US, h, tv, Reg, uhtr, vhtr, Kd, debug, type(ALE_CS), pointer :: CS !< Regridding parameters and options type(ocean_grid_type), intent(in ) :: G !< Ocean grid informations type(verticalGrid_type), intent(in ) :: GV !< Ocean vertical grid structure - type(unit_scale_type), intent(in ) :: US !< A dimensional unit scaling type + type(unit_scale_type), intent(in ) :: US !< A dimensional unit scaling type real, dimension(SZI_(G),SZJ_(G),SZK_(GV)), intent(inout) :: h !< Layer thicknesses [H ~> m or kg m-2] type(thermo_var_ptrs), intent(inout) :: tv !< Thermodynamic variable structure type(tracer_registry_type), pointer :: Reg !< Tracer registry structure real, dimension(SZIB_(G),SZJ_(G),SZK_(GV)), intent(inout) :: uhtr !< Zonal mass fluxes [H L2 ~> m3 or kg] real, dimension(SZI_(G),SZJB_(G),SZK_(GV)), intent(inout) :: vhtr !< Meridional mass fluxes [H L2 ~> m3 or kg] - real, dimension(SZI_(G),SZJ_(G),SZK_(GV)+1), intent(inout) :: Kd !< Input diffusivities [Z2 T-1 ~> m2 s-1] + real, dimension(SZI_(G),SZJ_(G),SZK_(GV)+1), intent(inout) :: Kd !< Input diffusivities + !!

It includes a bugfix in the library testing, and also bundles the macro for testing Fortran links to C libraries. Both of these macros were already in `ac/m4` but unused by `ac/deps`. No problems were observed in any recent FMS builds, although in principle they could have been affected by these errors. The issues were only detected when the macros were used in an unrelated project (LM3 land model). These issues are due to code duplication in `ac/m4` and `ac/deps/m4`. This separation was intended to draw a clear logical separation between MOM6 and its FMS dependency, and only provide what is required by each respective build. But perhaps there are some flaws in this thinking, and may warrant further discussion. --- ac/deps/m4/ax_fc_check_c_lib.m4 | 45 +++++++++++++++++++++++++++++++++ ac/deps/m4/ax_fc_check_lib.m4 | 13 +++++----- 2 files changed, 52 insertions(+), 6 deletions(-) create mode 100644 ac/deps/m4/ax_fc_check_c_lib.m4 diff --git a/ac/deps/m4/ax_fc_check_c_lib.m4 b/ac/deps/m4/ax_fc_check_c_lib.m4 new file mode 100644 index 0000000000..af5765282a --- /dev/null +++ b/ac/deps/m4/ax_fc_check_c_lib.m4 @@ -0,0 +1,45 @@ +dnl AX_FC_CHECK_C_LIB(LIBRARY, FUNCTION, +dnl [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND], +dnl [OTHER-LDFLAGS], [OTHER-LIBS]) +dnl +dnl This macro checks if a C library can be referenced by a Fortran compiler. +dnl +dnl Results are cached in `ax_fc_cv_c_lib_LIBRARY_FUNCTION`. +dnl +dnl NOTE: Might be possible to rewrite this to use `AX_FC_CHECK_BIND_C`. +dnl +AC_DEFUN([AX_FC_CHECK_C_LIB], [ + AS_VAR_PUSHDEF([ax_fc_C_Lib], [ax_fc_cv_c_lib_$1_$2]) + m4_ifval([$5], + [ax_fc_c_lib_msg_LDFLAGS=" with $5"], + [ax_fc_c_lib_msg_LDFLAGS=""] + ) + AC_CACHE_CHECK( + [for $2 in -l$1$ax_fc_c_lib_msg_LDFLAGS], [ax_fc_cv_c_lib_$1_$2], [ + ax_fc_check_c_lib_save_LDFLAGS=$LDFLAGS + LDFLAGS="$6 $LDFLAGS" + ax_fc_check_c_lib_save_LIBS=$LIBS + LIBS="-l$1 $7 $LIBS" + AC_LINK_IFELSE( + [AC_LANG_PROGRAM([],[dnl +dnl begin code block + interface + subroutine test() bind(c, name="$2") + end subroutine test + end interface + call test]) +dnl end code block + ], + [AS_VAR_SET([ax_fc_C_Lib], [yes])], + [AS_VAR_SET([ax_fc_C_Lib], [no])] + ) + LDFLAGS=$ax_fc_check_c_lib_save_LDFLAGS + LIBS=$ax_fc_check_c_lib_save_LIBS + ] + ) + AS_VAR_IF([ax_fc_C_Lib], [yes], + [m4_default([$3], [LIBS="-l$1 $LIBS"])], + [$4] + ) + AS_VAR_POPDEF([ax_fc_C_Lib]) +]) diff --git a/ac/deps/m4/ax_fc_check_lib.m4 b/ac/deps/m4/ax_fc_check_lib.m4 index c0accab6cd..a7f848cd60 100644 --- a/ac/deps/m4/ax_fc_check_lib.m4 +++ b/ac/deps/m4/ax_fc_check_lib.m4 @@ -18,7 +18,7 @@ dnl library with different -L flags, or perhaps other ld configurations. dnl dnl Results are cached in the ax_fc_cv_lib_LIBRARY_FUNCTION variable. dnl -AC_DEFUN([AX_FC_CHECK_LIB],[dnl +AC_DEFUN([AX_FC_CHECK_LIB],[ AS_VAR_PUSHDEF([ax_fc_Lib], [ax_fc_cv_lib_$1_$2]) m4_ifval([$6], [ax_fc_lib_msg_LDFLAGS=" with $6"], @@ -29,14 +29,15 @@ AC_DEFUN([AX_FC_CHECK_LIB],[dnl LDFLAGS="$6 $LDFLAGS" ax_fc_check_lib_save_LIBS=$LIBS LIBS="-l$1 $7 $LIBS" - AS_IF([test -n $3], + AS_IF([test -n "$3"], [ax_fc_use_mod="use $3"], [ax_fc_use_mod=""]) - AC_LINK_IFELSE([ - AC_LANG_PROGRAM([], [dnl + AC_LINK_IFELSE([dnl +dnl Begin 7-column code block +AC_LANG_PROGRAM([], [dnl $ax_fc_use_mod - call $2]dnl - ) + call $2])dnl +dnl End code block ], [AS_VAR_SET([ax_fc_Lib], [yes])], [AS_VAR_SET([ax_fc_Lib], [no])] From 7b7052e9b691468e650686d9ba38dade5c5b4ed5 Mon Sep 17 00:00:00 2001 From: Gustavo Marques Date: Wed, 6 Sep 2023 13:55:23 -0600 Subject: [PATCH 0834/1329] Describe local variables and make code consistent --- .../vertical/MOM_vert_friction.F90 | 169 ++++++++---------- 1 file changed, 75 insertions(+), 94 deletions(-) diff --git a/src/parameterizations/vertical/MOM_vert_friction.F90 b/src/parameterizations/vertical/MOM_vert_friction.F90 index 5a62e835f8..eab2f2d29d 100644 --- a/src/parameterizations/vertical/MOM_vert_friction.F90 +++ b/src/parameterizations/vertical/MOM_vert_friction.F90 @@ -166,7 +166,7 @@ module MOM_vert_friction integer :: id_au_vv = -1, id_av_vv = -1, id_au_gl90_vv = -1, id_av_gl90_vv = -1 integer :: id_du_dt_str = -1, id_dv_dt_str = -1 integer :: id_h_u = -1, id_h_v = -1, id_hML_u = -1 , id_hML_v = -1 - integer :: id_FPdiag_u = -1, id_FPdiag_v = -1 , id_FPw2x = -1 !W id_FPhbl_u = -1, id_FPhbl_v = -1 + integer :: id_FPw2x = -1 !W id_FPhbl_u = -1, id_FPhbl_v = -1 integer :: id_tauFP_u = -1, id_tauFP_v = -1 !W, id_FPtau2x_u = -1, id_FPtau2x_v = -1 integer :: id_FPtau2s_u = -1, id_FPtau2s_v = -1, id_FPtau2w_u = -1, id_FPtau2w_v = -1 integer :: id_taux_bot = -1, id_tauy_bot = -1 @@ -210,47 +210,40 @@ subroutine vertFPmix(L_diag, ui, vi, uold, vold, hbl_h, h, forces, dt, G, GV, US type(vertvisc_CS), pointer :: CS !< Vertical viscosity control structure ! local variables - !

These issues caused crashes during the ice-shelf velocity (SSA) solution, and ice shelf dynamics restarts were not bitwise identical. The issues were resolved with the following changes: -Added bed_elev to the ice shelf restart file (previously, bed_elev was instead calculated incorrectly after a restart). Also fixed the subsequent bed_elev pass_var call, where the halo update was failing due to an error in how an optional argument (CENTER) was passed. -Added additional pass_var/pass_vector calls upon ice shelf restarts to guarantee that all halos are properly filled. -Disabled the additional ice shelf flow solve (ice_shelf_solve_outer) after a restart, which was unnecessary and prevented bitwise identical restarts. -Fixed incorrect bounds for iterations within ice_shelf_solve_inner and for the basis functions in calc_shelf_visc This commit also sets the mol_wt argument to optional in the dummy function aof_set_coupler_flux (from ice_solo_driver/atmost_ocean_fluxes.F90), as that is how it is called from the FMS coupler.

It also adds the new runtime parameter MEKE_TOTAL_DEPTH_RHO to specify the density that is used to convert the bathymetric depth into a nominal ocean mass in non-Boussinesq mode when MEKE is enabled and MEKE_FIXED_TOTAL_DEPTH is true. There is a new element in the MEKE_CS type, and the scaled units of two other elements (cdrag and MEKE_min_depth_tot) are altered. The units of a total of 5 arguments to the private routines MEKE_equilibrium, MEKE_equilibrium_restoring, MEKE_lengthScales and MEKE_lengthScales_0d where changed consistently with the broader changes here. There is also a new vertical_grid type argument to MEKE_equilibrium_restoring. The units of 6 internal variables are changed, 2 new internal variable were added and 5 internal variables were eliminated. There are 4 places where multiplication by a GV%H_to_Z thickness rescaling factor was eliminated, while 4 instances that use GV%Rho0 directly were effectively replaced by the use of GV%H_to_RZ. All Boussinesq answers are bitwise identical, but answers will change in non-Boussinesq mode and there is a new runtime parameter the MOM_parameter_doc files for some non-Boussinesq simulations. --- src/parameterizations/lateral/MOM_MEKE.F90 | 125 +++++++++++---------- 1 file changed, 67 insertions(+), 58 deletions(-) diff --git a/src/parameterizations/lateral/MOM_MEKE.F90 b/src/parameterizations/lateral/MOM_MEKE.F90 index 3059ca1637..a44eec7727 100644 --- a/src/parameterizations/lateral/MOM_MEKE.F90 +++ b/src/parameterizations/lateral/MOM_MEKE.F90 @@ -75,15 +75,15 @@ module MOM_MEKE !! which is calculated at each time step. logical :: GM_src_alt !< If true, use the GM energy conversion form S^2*N^2*kappa rather !! than the streamfunction for the MEKE GM source term. - real :: MEKE_min_depth_tot !< The minimum total depth over which to distribute MEKE energy - !! sources from GM energy conversion [Z ~> m].

It incorrectly ignores files with externals it happens to contain both externals and a program unit. We resolve this by tracking whether we are inside or outside of a program unit while parsing each line. We ignore keywords which may appear in comments, as well as tokens which may contain `function` or `subroutine` as substrings. This method is not perfect; there are cases which will incorrectly report entering a block, but this method appears sufficient for all of our known codebases. This issue was detected when attempting to parse the AM2 source. While still far from a general solution, it is sufficient to handle a few of the more challenging cases encountered in AM2. --- ac/makedep | 45 +++++++++++++++++++++++++++++++++++++++------ 1 file changed, 39 insertions(+), 6 deletions(-) diff --git a/ac/makedep b/ac/makedep index 225a241b93..502250020b 100755 --- a/ac/makedep +++ b/ac/makedep @@ -16,6 +16,13 @@ re_use = re.compile(r"^ *use +([a-z_0-9]+)") re_cpp_include = re.compile(r"^ *# *include *[<\"']([a-zA-Z_0-9\.]+)[>\"']") re_f90_include = re.compile(r"^ *include +[\"']([a-zA-Z_0-9\.]+)[\"']") re_program = re.compile(r"^ *[pP][rR][oO][gG][rR][aA][mM] +([a-zA-Z_0-9]+)") +re_end = re.compile(r"^ *end *(module|procedure) ", re.IGNORECASE) +# NOTE: This excludes comments and tokens with substrings containing `function` +# or `subroutine`, but will fail if the keywords appear in other contexts. +re_procedure = re.compile( + r"^[^!]*(? 0: for h in cpp+inc: if h not in hlst and h in f2F.keys(): @@ -258,25 +266,49 @@ def scan_fortran_file(src_file): module_decl, used_modules, cpp_includes, f90_includes, programs = [], [], [], [], [] with io.open(src_file, 'r', errors='replace') as file: lines = file.readlines() + + external_namespace = True + + file_has_externals = False + for line in lines: match = re_module.match(line.lower()) if match: if match.group(1) not in 'procedure': # avoid "module procedure" statements module_decl.append(match.group(1)) + external_namespace = False + match = re_use.match(line.lower()) if match: used_modules.append(match.group(1)) + match = re_cpp_include.match(line) if match: cpp_includes.append(match.group(1)) + match = re_f90_include.match(line) if match: f90_includes.append(match.group(1)) + match = re_program.match(line) if match: programs.append(match.group(1)) + external_namespace = False + + match = re_end.match(line) + if match: + external_namespace = True + + # Check for any external procedures; if present, flag the file + # as a potential source of + # NOTE: This a very weak test that needs further modification + if external_namespace and not file_has_externals: + match = re_procedure.match(line) + if match: + file_has_externals = True + used_modules = [m for m in sorted(set(used_modules)) if m not in module_decl] -

The publicly visible interfaces to this module and the external routines it calls have already been revised, so only this file needs to be updated. The specific changes include: - Work with both thickness (h) and height change (dz) variables in energetic_PBL using thickness_to_dz to translate between the two. In Boussinesq mode, these are a simple rescaling by a constant factor, but in non-Boussinesq mode they vary by a factor of the specific volume. Some calculations are unnecessarily duplicated in Boussinesq mode, so this might slow the model slightly, but they are not duplicative in non-Boussinesq mode. - When in non-Boussinesq mode, use forces%tau_mag and tv%SpV_avg instead of forces%ustar and GV%Rho0 to determine the friction velocity and mechanical TKE input used in energetic_PBL, and to convert the local TKE to a turbulent velocity. This includes the addition of a new energy input argument and an interface specific volume argument to ePBL_column and the removal of an unused argument to find_mstar. - Use tau_mag_gustless times the in situ specfic volume instead of ustar_gustless to calculate the Langmuir number used by ePBL when it is run in non-Boussinesq mode. - The unused Ustar_mean argument to find_mstar was removed. This change involves the addition of 2 new arguments to ePBL_column and changes to the units of another argument. There are changes to the units of 2 elements of the energetic_PBL_CS type and 14 internal variables. This change includes the addition of 13 new internal variables, the removal of 8 internal variable (most of which were renamed to reflect their new units). With this change, 9 thickness to height conversion factors have been eliminated, and GV%Rho0 is only used in Boussinesq mode. All answers in Boussinesq mode are bitwise identical, but they change in non-Boussinesq mode cases that use ePBL, which no longer depend on the value of the Boussinesq reference density. --- .../vertical/MOM_energetic_PBL.F90 | 302 +++++++++++------- 1 file changed, 186 insertions(+), 116 deletions(-) diff --git a/src/parameterizations/vertical/MOM_energetic_PBL.F90 b/src/parameterizations/vertical/MOM_energetic_PBL.F90 index 17da7aceb3..380725b744 100644 --- a/src/parameterizations/vertical/MOM_energetic_PBL.F90 +++ b/src/parameterizations/vertical/MOM_energetic_PBL.F90 @@ -3,20 +3,20 @@ module MOM_energetic_PBL !

When in fully non-Boussinesq mode, there is no longer any dependence on the Boussinesq reference density. Rescaled the units of turbulent kinetic energy in the bulk mixed layer code to [H L2 T-2 ~> m3 s-2 or J m-2] to reduce the influence of the Boussinesq reference density in non-Boussinesq configurations, with similar changes to the internal units of diagnostics and energy sources. Also revised how Hmix_min is set in bulkmixedlayer_init to avoid any dependency on the Boussinesq reference density. Add a U_star argument to find_starting_TKE and use find_ustar to set it. In some places a thickness-based definition of U_star is used. Also added logic to the code setting the starting TKE and k_Ustar so that they supports a greater range of valid combinations of available input variables. Added the option of using non-Boussinesq energetic calculations in the bulk mixed layer code, which avoids any dependence on the Boussinesq reference density, but do the calculations with the approximation that specific volume is conserved during mixing, thereby ignoring certain weak thermobaric effects. The use of this new option is controlled by the new runtime parameter BML_NONBOUSSINESQ, which is false by default except in fully non-Boussinesq mode. All of the new code is wrapped in logical branches that are selected by the new logical variable CS%nonBous_energetics in the bulk mixed layer control structure. This option changes which equation of state routines are called by the bulk mixed layer module. When in non-Boussinesq mode, use forces%tau_mag and tv%SpV_avg instead of forces%ustar and GV%Rho0 to determine the surface TKE flux. Use SpV_avg to rescale opacity in non-Boussinesq mode via the use of an optional argument to extract_optics_slice Use a call to average_specific_vol to translate the mass of the mixed layer into the mixed layer thickness. As a part of these changes, there is extensive but systematic revision to the code. Within the bulkmixedlayer_CS type the units of 10 elements (mostly diagnostics) are changed, and there is one new logical element. There are 17 new arguments to internal subroutines in the bulk mixed layer module, while the units of another 11 are changed. There are 35 new or renamed internal variables, while the units of another 28 internal variables are changed. A total of 23 thickness conversion factors were eliminated, and the remaining references to the Boussinesq reference density are only used in Boussinesq mode. Apart from the new runtime parameter, the external interfaces are unchanged. By default, answers are bitwise identical for Boussinesq or semi-Boussinesq configurations, but there is a new entry (BML_NONBOUSINESQ) in some MOM_parameter_doc files, and answers do change in non-Boussinesq mode and become independent of the value of RHO_0. --- .../vertical/MOM_bulk_mixed_layer.F90 | 1339 ++++++++++++----- 1 file changed, 958 insertions(+), 381 deletions(-) diff --git a/src/parameterizations/vertical/MOM_bulk_mixed_layer.F90 b/src/parameterizations/vertical/MOM_bulk_mixed_layer.F90 index ceba8dad1a..c7e522eddc 100644 --- a/src/parameterizations/vertical/MOM_bulk_mixed_layer.F90 +++ b/src/parameterizations/vertical/MOM_bulk_mixed_layer.F90 @@ -3,10 +3,13 @@ module MOM_bulk_mixed_layer !

It also adds a new optional argument to extract_optics_slice to enable the use of the layer specific volumes to translate opacities into thickness-based units. The specific set of changes include: - Add the optional argument SpV_avg to extract_optics_slice and use it along with an appropriate value for opacity_scale to optionally convert the units of opacity from [Z-1 ~> m-1] to [H-1 ~> m-1 or m2 kg-1] in non-Boussinesq mode without making use of the Boussinesq reference density. - Use thickness_to_dz and work with internal variables in vertical distances in the denominator of diffusive flux calculations in differential_diffuse_T_S, diagnoseMLDbyDensityDifference and diagnoseMLDbyEnergy. - Refactored diagnoseMLDbyEnergy for probable efficiencies by calling the equation of state with contiguous arguments. - Use specific volume derivatives to calculate non-Boussinesq mode buoyancy fluxes in calculateBuoyancy_Flux1d and applyBoudaryFluxesInOut. - Use the inverse of SpV_avg rather than Rho0 in the calculation of the energy input used to drive river mixing when in non-Boussinesq mode. There are now separate thickness and depth change internal variables in several places to avoid any dependency on the Boussinesq reference density when in non-Boussinesq mode. A total of 8 rescaling factors were eliminated, and in one place, GV%Rho0 was replaced with GV%H_to_RZ. All Boussinesq answers are bitwise identical, but non-Boussinesq answers will change and become less dependent on the Boussinesq reference density, and there is a new optional argument to a publicly visible subroutine. --- .../vertical/MOM_diabatic_aux.F90 | 165 ++++++++++++------ 1 file changed, 108 insertions(+), 57 deletions(-) diff --git a/src/parameterizations/vertical/MOM_diabatic_aux.F90 b/src/parameterizations/vertical/MOM_diabatic_aux.F90 index 6a5e454d19..95c4d43ad3 100644 --- a/src/parameterizations/vertical/MOM_diabatic_aux.F90 +++ b/src/parameterizations/vertical/MOM_diabatic_aux.F90 @@ -15,6 +15,7 @@ module MOM_diabatic_aux use MOM_file_parser, only : get_param, log_param, log_version, param_file_type use MOM_forcing_type, only : forcing, extractFluxes1d, forcing_SinglePointPrint use MOM_grid, only : ocean_grid_type +use MOM_interface_heights, only : thickness_to_dz use MOM_interpolate, only : init_external_field, time_interp_external, time_interp_external_init use MOM_interpolate, only : external_field use MOM_io, only : slasher @@ -31,8 +32,8 @@ module MOM_diabatic_aux public diabatic_aux_init, diabatic_aux_end public make_frazil, adjust_salt, differential_diffuse_T_S, triDiagTS, triDiagTS_Eulerian -public find_uv_at_h, diagnoseMLDbyDensityDifference, applyBoundaryFluxesInOut, set_pen_shortwave -public diagnoseMLDbyEnergy +public find_uv_at_h, applyBoundaryFluxesInOut, set_pen_shortwave +public diagnoseMLDbyEnergy, diagnoseMLDbyDensityDifference !

Many factors of GV%H_to_Z or its inverse are cancelled out in MOM_wave_speed.F90 by working directly in thickness units. The code now uses specific volume derivatives to set the values of g_prime at interfaces when in non-Boussinesq mode, regardless of whether an equation of state is used. This commit also modifies the wave structure calculations in wave_speeds, which includes the use of thickness_to_dz, changes to the units of three arguments to wave_speeds and their counterparts in int_tide_CS, and a number of duplicated calculations of vertical extents mirroring the calculations of thicknesses. Some diagnostic conversion factors were modified accordingly in MOM_internal_tides. This commit involves changing the units of 19 internal variables in wave_speed and 17 internal variables in wave_speeds to use thickness units or other related units. There are 6 new or renamed internal variables in wave_speed and 10 new or renamed variables in wave_speeds. A total 34 thickness rescaling factors or references to GV%Rho0 were cancelled out or replaced. Missing comments describing the units of several real variables were also added. All answers are bitwise identical in Boussinesq mode, but answers do change in non-Boussinesq solutions that depend on the internal wave speed. This commit eliminates the dependencies of the non-Boussinesq wave speed calculations on the Boussinesq reference density. --- src/diagnostics/MOM_wave_speed.F90 | 588 ++++++++++++------ .../lateral/MOM_internal_tides.F90 | 17 +- 2 files changed, 390 insertions(+), 215 deletions(-) diff --git a/src/diagnostics/MOM_wave_speed.F90 b/src/diagnostics/MOM_wave_speed.F90 index c2b671f1c6..92c76001c7 100644 --- a/src/diagnostics/MOM_wave_speed.F90 +++ b/src/diagnostics/MOM_wave_speed.F90 @@ -7,11 +7,12 @@ module MOM_wave_speed use MOM_error_handler, only : MOM_error, FATAL, WARNING use MOM_file_parser, only : log_version use MOM_grid, only : ocean_grid_type +use MOM_interface_heights, only : thickness_to_dz use MOM_remapping, only : remapping_CS, initialize_remapping, remapping_core_h, interpolate_column use MOM_unit_scaling, only : unit_scale_type use MOM_variables, only : thermo_var_ptrs use MOM_verticalGrid, only : verticalGrid_type -use MOM_EOS, only : calculate_density_derivs +use MOM_EOS, only : calculate_density_derivs, calculate_specific_vol_derivs implicit none ; private @@ -89,27 +90,28 @@ subroutine wave_speed(h, tv, G, GV, US, cg1, CS, full_halos, use_ebt_mode, mono_ real, dimension(SZK_(GV)+1) :: & dRho_dT, & !

This halo_size argument is used in the call to thickness_to_dz in wave_speeds, and the call to wave_speeds in propagate_int_tides was modified accordingly. In addition, the loop bounds in the MOM_internal_tides code were modified to avoid excessive calculations over the full data domain, some of which would use uninitialized variables. Also modified the logic determining the value of diabatic_halo as returned by extract_diabatic_member to account for the wider halos that are needed when the internal tide code is used. This commit changes the interfaces publicly visible routines and it changes answers in cases when the internal_tides are used by doing calculations of the wave speeds in halo points that are used in that code. --- src/diagnostics/MOM_wave_speed.F90 | 38 +++--- .../lateral/MOM_internal_tides.F90 | 114 ++++++++++-------- .../vertical/MOM_diabatic_driver.F90 | 8 +- 3 files changed, 89 insertions(+), 71 deletions(-) diff --git a/src/diagnostics/MOM_wave_speed.F90 b/src/diagnostics/MOM_wave_speed.F90 index 92c76001c7..59dbfc184e 100644 --- a/src/diagnostics/MOM_wave_speed.F90 +++ b/src/diagnostics/MOM_wave_speed.F90 @@ -63,7 +63,7 @@ module MOM_wave_speed contains !> Calculates the wave speed of the first baroclinic mode. -subroutine wave_speed(h, tv, G, GV, US, cg1, CS, full_halos, use_ebt_mode, mono_N2_column_fraction, & +subroutine wave_speed(h, tv, G, GV, US, cg1, CS, halo_size, use_ebt_mode, mono_N2_column_fraction, & mono_N2_depth, modal_structure) type(ocean_grid_type), intent(in) :: G !< Ocean grid structure type(verticalGrid_type), intent(in) :: GV !< Vertical grid structure @@ -73,8 +73,8 @@ subroutine wave_speed(h, tv, G, GV, US, cg1, CS, full_halos, use_ebt_mode, mono_ type(thermo_var_ptrs), intent(in) :: tv !< Thermodynamic variables real, dimension(SZI_(G),SZJ_(G)), intent(out) :: cg1 !< First mode internal wave speed [L T-1 ~> m s-1] type(wave_speed_CS), intent(in) :: CS !< Wave speed control struct - logical, optional, intent(in) :: full_halos !< If true, do the calculation - !! over the entire computational domain. + integer, optional, intent(in) :: halo_size !< Width of halo within which to + !! calculate wave speeds logical, optional, intent(in) :: use_ebt_mode !< If true, use the equivalent !! barotropic mode instead of the first baroclinic mode. real, optional, intent(in) :: mono_N2_column_fraction !< The lower fraction @@ -158,7 +158,7 @@ subroutine wave_speed(h, tv, G, GV, US, cg1, CS, full_halos, use_ebt_mode, mono_ logical :: better_est !

This change reduces the parameters that need to be changed to go between equivalent Boussinesq and non-Boussinesq configurations to just BOUSSINESQ and SEMI_BOUSSINESQ. The previous default (false) is being retained for any Boussinesq or semi-Bousssinesq cases so that all answers and output are bitwise identical in those cases, but by default some non-Boussinesq solutions change answers, and there are changes to the MOM_parameter_doc files for those non-Boussinesq cases. --- src/initialization/MOM_state_initialization.F90 | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/initialization/MOM_state_initialization.F90 b/src/initialization/MOM_state_initialization.F90 index fc676781bc..69d59961ec 100644 --- a/src/initialization/MOM_state_initialization.F90 +++ b/src/initialization/MOM_state_initialization.F90 @@ -2558,7 +2558,7 @@ subroutine MOM_temp_salt_initialize_from_Z(h, tv, depth_tot, G, GV, US, PF, just call get_param(PF, mdl, "Z_INIT_REMAP_GENERAL", remap_general, & "If false, only initializes to z* coordinates.

This commit adds the new runtime parameter FULL_DEPTH_EADY_GROWTH_RATE to indicate that the denominator of an Eady growth rate calculation should be based on the full depth of the water column, rather than the nominal depth of the bathymetry. The new option is only the default for fully non-Boussinesq cases. A primordial horizontal indexing bug was corrected in the v-direction slope calculation. Because it only applies for very shallow bathymetry, does not appear to impact any existing test cases and went undetected for at least 12 years, it was corrected directly rather than wrapping in another new runtime flag. However, this bug is being retained for now in a comment to help with review and debugging if the answers should change unexpectedly in some yet-to-be identified configuration. Two debugging checksums were added for the output variables calculated in calc_resoln_function. The case of some indices was corrected to follow the MOM6 soft convention using case to indicate the staggering position of variables. The previously incorrect units of one comment were also fixed. There is a new logical element in the VarMix_CS type. To accommodate these changes there are three new internal variables in calc_slope_functions_using_just_e. A total of 9 GV%H_to_Z conversion factors were eliminated with this commit. N2 is no longer calculated separately in calc_slope_functions_using_just_e, but this code is left in a comment as it may be instructive. This commit involved changing the units of one internal variable in calc_QG_Leith_viscosity to use inverse thickness units (as its descriptive comment already indicated). There are already known problems with calc_QG_Leith_viscosity as documented with a fatal error; this will be addressed in a subsequent commit. All answers are bitwise identical in the existing MOM6-examples test suite, but they will change when fully non-Boussinesq, and there is a new entry in some MOM_parameter_doc files. --- .../lateral/MOM_lateral_mixing_coeffs.F90 | 148 ++++++++++++------ 1 file changed, 103 insertions(+), 45 deletions(-) diff --git a/src/parameterizations/lateral/MOM_lateral_mixing_coeffs.F90 b/src/parameterizations/lateral/MOM_lateral_mixing_coeffs.F90 index 1bf416b00a..4f1dbb89ac 100644 --- a/src/parameterizations/lateral/MOM_lateral_mixing_coeffs.F90 +++ b/src/parameterizations/lateral/MOM_lateral_mixing_coeffs.F90 @@ -10,7 +10,7 @@ module MOM_lateral_mixing_coeffs use MOM_domains, only : create_group_pass, do_group_pass use MOM_domains, only : group_pass_type, pass_var, pass_vector use MOM_file_parser, only : get_param, log_version, param_file_type -use MOM_interface_heights, only : find_eta +use MOM_interface_heights, only : find_eta, thickness_to_dz use MOM_isopycnal_slopes, only : calc_isoneutral_slopes use MOM_grid, only : ocean_grid_type use MOM_unit_scaling, only : unit_scale_type @@ -59,16 +59,21 @@ module MOM_lateral_mixing_coeffs !!

Regardless, the advice to get around this throttling seems to be to use the Codecov token associated with the project. The .testing Makefile was modified to use this token if provided, and the GitHub Actions environment now attempts to fetch this from the secrets of the repository. Hopefully individual groups can set this for their own projects, and it will fall back to anonymous upload if unset, but I guess we'll have to see how this plays out. --- .github/workflows/coverage.yml | 4 ++++ .testing/Makefile | 10 +++++++++- 2 files changed, 13 insertions(+), 1 deletion(-) diff --git a/.github/workflows/coverage.yml b/.github/workflows/coverage.yml index 9922840420..a54fda32a6 100644 --- a/.github/workflows/coverage.yml +++ b/.github/workflows/coverage.yml @@ -42,7 +42,11 @@ jobs: - name: Report coverage to CI (PR) if: github.event_name == 'pull_request' run: make report.cov REQUIRE_COVERAGE_UPLOAD=true + env: + CODECOV_TOKEN: ${{ secrets.CODECOV_TOKEN }} - name: Report coverage to CI (Push) if: github.event_name != 'pull_request' run: make report.cov + env: + CODECOV_TOKEN: ${{ secrets.CODECOV_TOKEN }} diff --git a/.testing/Makefile b/.testing/Makefile index d6b06893fe..c2ab27741a 100644 --- a/.testing/Makefile +++ b/.testing/Makefile @@ -571,13 +571,21 @@ endef # Upload coverage reports CODECOV_UPLOADER_URL ?= https://uploader.codecov.io/latest/linux/codecov +CODECOV_TOKEN ?= + +ifdef CODECOV_TOKEN + CODECOV_TOKEN_ARG = -t $(CODECOV_TOKEN) +else + CODECOV_TOKEN_ARG = +endif + codecov: curl -s $(CODECOV_UPLOADER_URL) -o $@ chmod +x codecov .PHONY: report.cov report.cov: run.cov codecov - ./codecov -R build/cov -Z -f "*.gcov" \ + ./codecov $(CODECOV_TOKEN_ARG) -R build/cov -Z -f "*.gcov" \ > build/cov/codecov.out \ 2> build/cov/codecov.err \ && echo -e "${MAGENTA}Report uploaded to codecov.${RESET}" \ From 7cef1e450e9813af9a0ae3d86ae3b3fa58b39a32 Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Thu, 27 Jul 2023 07:39:56 -0400 Subject: [PATCH 0864/1329] +Rename OBC sea surface height variables Renamed OBC related variables to emphasize that they are sea surface heights, and not sea surface heights or total column mass depending on the Boussinesq approximation. Also changed the units of these renamed variables to [Z ~> m] instead of [H ~> m or kg m-2]. The renamed element of the OBC_segment_type is eta (which is now SSH). The renamed and rescaled elements of the BT_OBC_type are H_[uv] (which are now dZ_[uv]) and eta_outer_[uv] (which are now SSH_outer_[uv]). The internal variables H_[uv] and h_in in apply_velocity_OBCs are now dZ_[uv] and ssh_in. Tidal_elev in update_OBC_segment_data and cff_eta in tidal_bay_set_OBC_data were rescaled but not renamed. There is also a new vertical grid type argument to apply_velocity_OBCs for use in changing the scaling of the SSH variables. A total of 11 GV%Z_to_H or GV%H_to_Z rescaling factors were cancelled out as a result of these changes, while 16 new ones were added, but most of these will in turn be dealt with in a follow-on commit that enables the use of OBCs in non-Boussinesq mode. Because any cases that use Flather open boundary conditions with the non-Boussinesq mode issue a fatal error, all answers are bitwise identical, but there are changes to the names and units of elements in a transparent type. --- src/core/MOM_barotropic.F90 | 93 ++++++++++++++------------- src/core/MOM_open_boundary.F90 | 22 ++++--- src/user/Kelvin_initialization.F90 | 8 +-- src/user/tidal_bay_initialization.F90 | 6 +- 4 files changed, 66 insertions(+), 63 deletions(-) diff --git a/src/core/MOM_barotropic.F90 b/src/core/MOM_barotropic.F90 index 4c600d37d2..af2ccaa487 100644 --- a/src/core/MOM_barotropic.F90 +++ b/src/core/MOM_barotropic.F90 @@ -71,8 +71,8 @@ module MOM_barotropic type, private :: BT_OBC_type real, allocatable :: Cg_u(:,:) !< The external wave speed at u-points [L T-1 ~> m s-1]. real, allocatable :: Cg_v(:,:) !< The external wave speed at u-points [L T-1 ~> m s-1]. - real, allocatable :: H_u(:,:) !< The total thickness at the u-points [H ~> m or kg m-2]. - real, allocatable :: H_v(:,:) !< The total thickness at the v-points [H ~> m or kg m-2]. + real, allocatable :: dZ_u(:,:) !< The total vertical column extent at the u-points [Z ~> m]. + real, allocatable :: dZ_v(:,:) !< The total vertical column extent at the v-points [Z ~> m]. real, allocatable :: uhbt(:,:) !< The zonal barotropic thickness fluxes specified !! for open boundary conditions (if any) [H L2 T-1 ~> m3 s-1 or kg s-1]. real, allocatable :: vhbt(:,:) !< The meridional barotropic thickness fluxes specified @@ -81,10 +81,10 @@ module MOM_barotropic !! as set by the open boundary conditions [L T-1 ~> m s-1]. real, allocatable :: vbt_outer(:,:) !< The meridional velocities just outside the domain, !! as set by the open boundary conditions [L T-1 ~> m s-1]. - real, allocatable :: eta_outer_u(:,:) !< The surface height outside of the domain - !! at a u-point with an open boundary condition [H ~> m or kg m-2]. - real, allocatable :: eta_outer_v(:,:) !< The surface height outside of the domain - !! at a v-point with an open boundary condition [H ~> m or kg m-2]. + real, allocatable :: SSH_outer_u(:,:) !< The surface height outside of the domain + !! at a u-point with an open boundary condition [Z ~> m]. + real, allocatable :: SSH_outer_v(:,:) !< The surface height outside of the domain + !! at a v-point with an open boundary condition [Z ~> m]. logical :: apply_u_OBCs !< True if this PE has an open boundary at a u-point. logical :: apply_v_OBCs !< True if this PE has an open boundary at a v-point. !>@{ Index ranges for the open boundary conditions @@ -2338,7 +2338,7 @@ subroutine btstep(U_in, V_in, eta_in, dt, bc_accel_u, bc_accel_v, forces, pbce, !$OMP single call apply_velocity_OBCs(OBC, ubt, vbt, uhbt, vhbt, & ubt_trans, vbt_trans, eta, ubt_old, vbt_old, CS%BT_OBC, & - G, MS, US, iev-ie, dtbt, bebt, use_BT_cont, integral_BT_cont, & + G, MS, GV, US, iev-ie, dtbt, bebt, use_BT_cont, integral_BT_cont, & n*dtbt, Datu, Datv, BTCL_u, BTCL_v, uhbt0, vhbt0, & ubt_int_prev, vbt_int_prev, uhbt_int_prev, vhbt_int_prev) !$OMP end single @@ -2908,11 +2908,11 @@ end subroutine set_dtbt !!

This includes calculating the column-average specific volume in step_MOM_dyn_split_RK2 and passing it as a new argument to btstep. Inside of btstep, this is copied over into a wide halo array and then passed on to set_up_BT_OBC and apply_velocity_OBCs, where it is used to determine the free surface height or the vertical column extent (in [Z ~> m]) from eta for use in the Flather radiation open boundary conditions. In addition, there are several places in MOM_barotropic related to the open boundary conditions where the usual G%bathyT needed to be replaced with its wide-halo counterpart, CS%bathyT. Also, a test was added for massless OBC columns in apply_velocity_OBCs, which are then assumed to be dry rather than dividing by zero. A fatal error message that is triggered in the case of Flather open boundary conditions in non-Boussiesq mode was removed. With this change, all Boussinesq answers are bitwise identical, but non-Boussinesq cases with Flather open boundary conditions are now working and giving answers that are qualitatively similar to the Boussinesq cases. --- src/core/MOM_barotropic.F90 | 162 +++++++++++++++++++--------- src/core/MOM_dynamics_split_RK2.F90 | 17 ++- 2 files changed, 125 insertions(+), 54 deletions(-) diff --git a/src/core/MOM_barotropic.F90 b/src/core/MOM_barotropic.F90 index af2ccaa487..4a5dba294a 100644 --- a/src/core/MOM_barotropic.F90 +++ b/src/core/MOM_barotropic.F90 @@ -306,6 +306,7 @@ module MOM_barotropic type(group_pass_type) :: pass_ubt_Cor !< Handle for a group halo pass type(group_pass_type) :: pass_ubta_uhbta !< Handle for a group halo pass type(group_pass_type) :: pass_e_anom !< Handle for a group halo pass + type(group_pass_type) :: pass_SpV_avg !< Handle for a group halo pass !>@{ Diagnostic IDs integer :: id_PFu_bt = -1, id_PFv_bt = -1, id_Coru_bt = -1, id_Corv_bt = -1 @@ -422,7 +423,7 @@ module MOM_barotropic subroutine btstep(U_in, V_in, eta_in, dt, bc_accel_u, bc_accel_v, forces, pbce, & eta_PF_in, U_Cor, V_Cor, accel_layer_u, accel_layer_v, & eta_out, uhbtav, vhbtav, G, GV, US, CS, & - visc_rem_u, visc_rem_v, ADp, OBC, BT_cont, eta_PF_start, & + visc_rem_u, visc_rem_v, SpV_avg, ADp, OBC, BT_cont, eta_PF_start, & taux_bot, tauy_bot, uh0, vh0, u_uh0, v_vh0, etaav) type(ocean_grid_type), intent(inout) :: G !< The ocean's grid structure. type(verticalGrid_type), intent(in) :: GV !< The ocean's vertical grid structure. @@ -472,6 +473,8 @@ subroutine btstep(U_in, V_in, eta_in, dt, bc_accel_u, bc_accel_v, forces, pbce, !! viscosity is applied, in the zonal direction [nondim]. !!

This functionality is retained here, but now setting u_face_mask or v_face_mask to 5 enforces a Dirichlet boundary for u-velocity only along the respective cell face. Similarly, setting u_face_mask or v_face_mask to 6 enforces the Dirichlet boundary for v-velocity only along the respective cell face. This functionality is required for most ice-sheet modeling configurations, e.g. the idealized MISMIP+ configuration requires setting v-velocity only to 0 along its lateral boundaries, but with free-slip conditions enforced for u-velocity. Adding this capability required changes throughout the ice-shelf code. Further changes were needed for how driving stress and Neummann conditions at computational boundaries are calculated in subroutine calc_shelf_driving_stress, and calls to subroutine apply_boundary_values were eliminated because they were not justified and caused errors. The new boundary treatment was tested by comparing simulated and analytical solutions for 1-D ice shelf flow with free-slip lateral boundary conditions and positive u_velocity enforced at the western boundary. This required the addition of a new parameter ADVECT_SHELF, which if false (as in the 1-D test case), turns off ice-shelf thickness evolution. By default, ADVECT_SHELF=True. The new boundary treatment was also justified in 2-D by correctly simulating the expected MISMIP+ steady-state. --- src/ice_shelf/MOM_ice_shelf_dynamics.F90 | 199 ++++++++++++--------- src/ice_shelf/MOM_ice_shelf_initialize.F90 | 2 +- 2 files changed, 120 insertions(+), 81 deletions(-) diff --git a/src/ice_shelf/MOM_ice_shelf_dynamics.F90 b/src/ice_shelf/MOM_ice_shelf_dynamics.F90 index cefe251edd..98e2f3600b 100644 --- a/src/ice_shelf/MOM_ice_shelf_dynamics.F90 +++ b/src/ice_shelf/MOM_ice_shelf_dynamics.F90 @@ -54,11 +54,14 @@ module MOM_ice_shelf_dynamics !! not vertices.

Note that when using one quadrature point (ice_viscosity_compute == MODEL), array ice_visc(:,:) is the cell-centered ice viscosity. When using four quadrature points (ice_viscosity_compute == MODEL_QUADRATURE), ice_visc(:,:) is the cell-centered ice viscosity divided by the effective stress, Ee, which varies between each quadrature point and is saved in a separate array CS%Ee(:,:,:). In the SSA, ice viscosity is calculated for a cell with indices i,j as ice_visc(i,j) * Ee, where Ee=1 if using one quadrature point for viscosity and Ee=CS%Ee(i,j,k) if using four quad points (where k the current quad point). Also note the post_data call for ice_visc when using four quad points, where Ice_visc is outputted for visualization from a cell as ice_visc(i,j)*Ee_av(i,j), where Ee_av(i,j) is the average Ee in the cell. --- src/ice_shelf/MOM_ice_shelf_dynamics.F90 | 264 ++++++++++++++++------- 1 file changed, 192 insertions(+), 72 deletions(-) diff --git a/src/ice_shelf/MOM_ice_shelf_dynamics.F90 b/src/ice_shelf/MOM_ice_shelf_dynamics.F90 index 98e2f3600b..bb9de629f7 100644 --- a/src/ice_shelf/MOM_ice_shelf_dynamics.F90 +++ b/src/ice_shelf/MOM_ice_shelf_dynamics.F90 @@ -82,6 +82,7 @@ module MOM_ice_shelf_dynamics real, pointer, dimension(:,:) :: tmask => NULL() !< A mask on tracer points that is 1 where there is ice. real, pointer, dimension(:,:) :: ice_visc => NULL() !< Glen's law ice viscosity (Pa s), !! in [R L2 T-1 ~> kg m-1 s-1]. + real, pointer, dimension(:,:,:) :: Ee => NULL() !< Glen's effective strain-rate ** (1-n)/(n) real, pointer, dimension(:,:) :: AGlen_visc => NULL() !< Ice-stiffness parameter in Glen's law ice viscosity, !! often in [Pa-3 s-1] if n_Glen is 3. real, pointer, dimension(:,:) :: thickness_bdry_val => NULL() !< The ice thickness at an inflowing boundary [Z ~> m]. @@ -273,6 +274,7 @@ subroutine register_ice_shelf_dyn_restarts(G, US, param_file, CS, restart_CS) allocate(CS%v_shelf(IsdB:IedB,JsdB:JedB), source=0.0) allocate(CS%t_shelf(isd:ied,jsd:jed), source=T_shelf_missing) !

This includes changes to the scaled units of the Kd_int argument to diapyc_energy_req_calc and the Kd argument to diapyc_energy_req_calc and the addition of a new argument to diapyc_energy_req_calc. A call to thickness_to_dz is used for the thickness unit conversions. There are 5 new internal variables, and changes to the units of several others. These routines are not actively used in MOM6 solutions, but instead they are used for testing and debugging new code, so there are no changes to solutions, but the results of these routines can differ in fully non-Boussinesq mode. --- .../vertical/MOM_diapyc_energy_req.F90 | 120 +++++++++++------- 1 file changed, 77 insertions(+), 43 deletions(-) diff --git a/src/parameterizations/vertical/MOM_diapyc_energy_req.F90 b/src/parameterizations/vertical/MOM_diapyc_energy_req.F90 index bbc4c9bf96..32b0423cd9 100644 --- a/src/parameterizations/vertical/MOM_diapyc_energy_req.F90 +++ b/src/parameterizations/vertical/MOM_diapyc_energy_req.F90 @@ -6,13 +6,14 @@ module MOM_diapyc_energy_req !! \author By Robert Hallberg, May 2015 use MOM_diag_mediator, only : diag_ctrl, Time_type, post_data, register_diag_field +use MOM_EOS, only : calculate_specific_vol_derivs, calculate_density use MOM_error_handler, only : MOM_error, FATAL, WARNING, MOM_mesg, is_root_pe -use MOM_file_parser, only : get_param, log_version, param_file_type -use MOM_grid, only : ocean_grid_type -use MOM_unit_scaling, only : unit_scale_type -use MOM_variables, only : thermo_var_ptrs -use MOM_verticalGrid, only : verticalGrid_type -use MOM_EOS, only : calculate_specific_vol_derivs, calculate_density +use MOM_file_parser, only : get_param, log_version, param_file_type +use MOM_grid, only : ocean_grid_type +use MOM_interface_heights, only : thickness_to_dz +use MOM_unit_scaling, only : unit_scale_type +use MOM_variables, only : thermo_var_ptrs +use MOM_verticalGrid, only : verticalGrid_type implicit none ; private @@ -59,20 +60,25 @@ subroutine diapyc_energy_req_test(h_3d, dt, tv, G, GV, US, CS, Kd_int) real, intent(in) :: dt !< The amount of time covered by this call [T ~> s]. type(diapyc_energy_req_CS), pointer :: CS !< This module's control structure. real, dimension(G%isd:G%ied,G%jsd:G%jed,GV%ke+1), & - optional, intent(in) :: Kd_int !< Interface diffusivities [Z2 T-1 ~> m2 s-1]. + optional, intent(in) :: Kd_int !< Interface diffusivities [H Z T-1 ~> m2 s-1 or kg m-1 s-1] !

Also removed find_PE_chg_orig from MOM_diapyc_energy_req.F90 and the old_PE_calc code that calls it. Extra values were also added to Te, Te_a and Te_b and the equivalent salinity variables so that the logical branches at (K==2) and (K=nz) could be simplied out of diapyc_energy_req_calc. Because old_PE_calc had been hard-coded to .false., all answers are bitwise identical. --- .../vertical/MOM_diapyc_energy_req.F90 | 548 ++++-------------- 1 file changed, 121 insertions(+), 427 deletions(-) diff --git a/src/parameterizations/vertical/MOM_diapyc_energy_req.F90 b/src/parameterizations/vertical/MOM_diapyc_energy_req.F90 index 32b0423cd9..7ca432fea4 100644 --- a/src/parameterizations/vertical/MOM_diapyc_energy_req.F90 +++ b/src/parameterizations/vertical/MOM_diapyc_energy_req.F90 @@ -185,11 +185,7 @@ subroutine diapyc_energy_req_calc(h_in, dz_in, T_in, S_in, Kd, energy_Kd, dt, tv dSV_dT, & !

This is required for MISMIP+. A constant SMB can also be used from the MOM driver for coupled ice-shelf/ocean experiments (e.g. MISOMIP). - The new, constant SMB is passed into solo_step_ice_shelf, where change_thickness_using_precip is called - Added capability to save both non-time-stamped and time-stamped restart files when using the ice shelf solo driver. This is useful for debugging. - slight reorganization to when ice shelf post_data calls are made - Added safety checks to diag_mediator_end() so that it works with the ice shelf solo-driver, which now calls it instead of (now removed) solo_ice_shelf_diag_mediator_end() routine. Removed the runtime parameter SAVE_BOTH_RESTARTS from the ice shelf solo-driver, which is no longer needed. --- .../ice_solo_driver/ice_shelf_driver.F90 | 48 +++++++++++--- config_src/drivers/solo_driver/MOM_driver.F90 | 6 +- src/framework/MOM_diag_mediator.F90 | 64 +++++++++++-------- src/ice_shelf/MOM_ice_shelf.F90 | 20 ++++-- src/ice_shelf/MOM_ice_shelf_dynamics.F90 | 2 +- src/ice_shelf/MOM_ice_shelf_initialize.F90 | 49 +++++++++++++- 6 files changed, 141 insertions(+), 48 deletions(-) diff --git a/config_src/drivers/ice_solo_driver/ice_shelf_driver.F90 b/config_src/drivers/ice_solo_driver/ice_shelf_driver.F90 index 8ea0867d03..f91595bd51 100644 --- a/config_src/drivers/ice_solo_driver/ice_shelf_driver.F90 +++ b/config_src/drivers/ice_solo_driver/ice_shelf_driver.F90 @@ -24,7 +24,7 @@ program Shelf_main use MOM_cpu_clock, only : cpu_clock_id, cpu_clock_begin, cpu_clock_end use MOM_cpu_clock, only : CLOCK_COMPONENT use MOM_debugging, only : MOM_debugging_init - use MOM_diag_mediator, only : diag_mediator_init, diag_mediator_infrastructure_init + use MOM_diag_mediator, only : diag_mediator_init, diag_mediator_infrastructure_init, set_axes_info use MOM_diag_mediator, only : diag_mediator_end, diag_ctrl, diag_mediator_close_registration use MOM_domains, only : MOM_infra_init, MOM_infra_end use MOM_domains, only : MOM_domains_init, clone_MOM_domain, pass_var @@ -54,6 +54,8 @@ program Shelf_main use MOM_verticalGrid, only : verticalGrid_type, verticalGridInit, verticalGridEnd use MOM_write_cputime, only : write_cputime, MOM_write_cputime_init use MOM_write_cputime, only : write_cputime_start_clock, write_cputime_CS + use MOM_forcing_type, only : forcing + use MOM_ice_shelf_initialize, only : initialize_ice_SMB use MOM_ice_shelf, only : initialize_ice_shelf, ice_shelf_end, ice_shelf_CS use MOM_ice_shelf, only : ice_shelf_save_restart, solo_step_ice_shelf @@ -75,7 +77,9 @@ program Shelf_main !

An issue with horizontal length scaling was corrected by using G%Rad_Earth_L in place of G%Rad_Earth in spherical_harmonics_init. There are new optional tmp_scale arguments to calc_SAL and spherical_harmonics_forward to allow the rescaling to be undone before calling the reproducing sums. This commit also modifies the call to the reproducing sums in spherical_harmonics_forward so that all real or imaginary components are calculated with a single call, which reduces the cost of the SAL calculation reproducing sums from about 6.7 times the cost with non-reproducing sums to just 5.5 times as much in testing with the tides_025 test case. There is also code added to avoid NaNs arising from a square root operating on a negative argument from a 32-bit integer roll-over when a very large number of harmonics components (more than 1024 x 1024) are unadvisedly being used. While this commit corrects the dimensional scaling when HARMONICS_SAL is true, all answers are bitwise identical when no rescaling is used or when the spherical harmonics SAL is not used. There are new optional arguments to two publicly visible interfaces. --- src/core/MOM_PressureForce_FV.F90 | 6 +-- src/core/MOM_PressureForce_Montgomery.F90 | 4 +- .../lateral/MOM_self_attr_load.F90 | 14 ++++--- .../lateral/MOM_spherical_harmonics.F90 | 42 ++++++++++++------- 4 files changed, 41 insertions(+), 25 deletions(-) diff --git a/src/core/MOM_PressureForce_FV.F90 b/src/core/MOM_PressureForce_FV.F90 index 64df200f31..5fb3ade634 100644 --- a/src/core/MOM_PressureForce_FV.F90 +++ b/src/core/MOM_PressureForce_FV.F90 @@ -319,7 +319,7 @@ subroutine PressureForce_FV_nonBouss(h, tv, PFu, PFv, G, GV, US, CS, ALE_CSp, p_ SSH(i,j) = (za(i,j) - alpha_ref*p(i,j,1)) * I_gEarth - G%Z_ref & - max(-G%bathyT(i,j)-G%Z_ref, 0.0) enddo ; enddo - call calc_SAL(SSH, e_sal, G, CS%SAL_CSp) + call calc_SAL(SSH, e_sal, G, CS%SAL_CSp, tmp_scale=US%Z_to_m) if ((CS%tides_answer_date>20230630) .or.

Because p_surf_EOS is a non-mandatory restart field, there is no problem restarting the run from a restart file created by an older version of the model. The solutions themselves are bitwise identical. This change requires that tv%p_surf is treated as an allocatable pointer to its own array rather than being used as a pointer to the p_surf element of the fluxes or forces structures so that it can be registered as a restart field. At some point tv%p_surf could be converted into an allocatable array instead of a pointer, but this would require more extensive code refactoring.

Setting GL_couple=.true. will determine the grounding based on ocean column thickness rather than the typical the hydrostatic equilibrium condition. This has the advantage of accounting for changes in sea level, tides, etc. However, it has the disadvantage of not working with the same thoroughly-tested sub-element grounding line parameterization used for the hydrostatic condition. Instead, it accounts for sub-element grounding line movement by, during the SSA solution, using a grounding mask averaged over all ocean (sub)steps that completed since the last SSA solve. Unlike the hydrostatic sub-element parameterization, the dependence of the GL_couple=.true. scheme on grid resolution has not yet been determined. Qualitatively similar grounding line retreat/advance behavior is achieved with both approaches for MISOMIP IceOcean1 on a 2km grid, but GL_couple=.true. results in a rougher grounding line position with less retreat. Note that this commit also fixed a bug in applying the hydrostatic grounding line approach without its sub-element parameterization (though the sub-element parameterization should also be used anyway). --- src/ice_shelf/MOM_ice_shelf.F90 | 1 + src/ice_shelf/MOM_ice_shelf_dynamics.F90 | 89 ++++++++++++++---------- 2 files changed, 55 insertions(+), 35 deletions(-) diff --git a/src/ice_shelf/MOM_ice_shelf.F90 b/src/ice_shelf/MOM_ice_shelf.F90 index d7aacef8ed..5c67a66262 100644 --- a/src/ice_shelf/MOM_ice_shelf.F90 +++ b/src/ice_shelf/MOM_ice_shelf.F90 @@ -1402,6 +1402,7 @@ subroutine initialize_ice_shelf(param_file, ocn_grid, Time, CS, diag, Time_init, "will be called.

This required adding visc%taux and visc%taux (stress on the ocean under ice shelves) to the ocean restart file. Furthermore, ice shelf geometry-related variables needed to be updated and their halo cells filled (within subroutine update_ice_shelf) before (rather than after) calculating shelf fluxes and pressure to the ocean (subroutine add_shelf_flux). Also fixed a bug to calculate ISS%mass_shelf properly in ice-shelf cells that are only partially-filled (ice-shelf area < cell area) due to advection of the ice-shelf front. * Modified the scheme that attempts to enforce a constant sea level in coupled ice-sheet/ocean runs, where balancing fluxes are applied to part/all of the open ocean to offset the sea level effects caused by changes in ice sheet mass on the ocean. The old scheme assumes the entire ice sheet is floating, and is retained here for the case where CS$override_shelf_movement==.true. and CS%mass_from_file (this approach is used for the MISOMIP tests without a dynamic ice sheet). The new scheme (which is needed for the MISOMIP tests with a dynamic ice sheet, e.g. IceOcean1r and IceOcean1a), accounts for the more general case where some of the ice sheet is grounded. In either case, the ocean balancing fluxes are applied over the entirety of the ice-sheet-free ocean by default. However, if the new parameter CONST_SEA_LEVEL_MISOMIP==.true., the balancing flux is only applied where x>=790 km, which is the sponge region for the MISOMIP tests. The new scheme also requires calculation of ice sheet dHdT, which is now calculated and optionally saved as a useful diagnositc field for any ice sheet simulation. * Eliminated array syntax and added inverse dt variables where needed --- src/core/MOM.F90 | 2 +- src/ice_shelf/MOM_ice_shelf.F90 | 88 +++++++++++++------ src/ice_shelf/MOM_ice_shelf_dynamics.F90 | 58 +++++++++++- src/ice_shelf/MOM_ice_shelf_state.F90 | 4 +- .../vertical/MOM_set_viscosity.F90 | 22 ++++- 5 files changed, 143 insertions(+), 31 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index a823ce1744..e1fa004fb8 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -2752,7 +2752,7 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, & CS%tracer_Reg, restart_CSp) call MEKE_alloc_register_restart(HI, US, param_file, CS%MEKE, restart_CSp) - call set_visc_register_restarts(HI, GV, US, param_file, CS%visc, restart_CSp) + call set_visc_register_restarts(HI, G, GV, US, param_file, CS%visc, restart_CSp, use_ice_shelf) call mixedlayer_restrat_register_restarts(HI, GV, US, param_file, & CS%mixedlayer_restrat_CSp, restart_CSp) diff --git a/src/ice_shelf/MOM_ice_shelf.F90 b/src/ice_shelf/MOM_ice_shelf.F90 index 5c67a66262..b435b0a677 100644 --- a/src/ice_shelf/MOM_ice_shelf.F90 +++ b/src/ice_shelf/MOM_ice_shelf.F90 @@ -50,7 +50,7 @@ module MOM_ice_shelf use MOM_EOS, only : EOS_type, EOS_init use MOM_ice_shelf_dynamics, only : ice_shelf_dyn_CS, update_ice_shelf, write_ice_shelf_energy use MOM_ice_shelf_dynamics, only : register_ice_shelf_dyn_restarts, initialize_ice_shelf_dyn -use MOM_ice_shelf_dynamics, only : ice_shelf_min_thickness_calve +use MOM_ice_shelf_dynamics, only : ice_shelf_min_thickness_calve, change_in_draft use MOM_ice_shelf_dynamics, only : ice_time_step_CFL, ice_shelf_dyn_end use MOM_ice_shelf_initialize, only : initialize_ice_thickness !MJH use MOM_ice_shelf_initialize, only : initialize_ice_shelf_boundary @@ -177,6 +177,8 @@ module MOM_ice_shelf logical :: const_gamma !< If true, gamma_T is specified by the user. logical :: constant_sea_level !< if true, apply an evaporative, heat and salt !! fluxes.

(DO_UNIT_TESTS was an existing macro but it might be uneeded) - These programs are compiled with code coverage - Added list of programs in config_src/drivers/timing_tests - These programs are compiled with optimization and no coverage - Fixed rule for building UNIT_EXECS (which did not re-build properly because the central Makefile was trying to model the dependencies even though those dependencies are in the build/unit/Makefile.dep) - Added convenient targets build.unit, run.unit, build.timing, run.timing - Timing tests currently time a loop over 1000 calls (so that the resolution of the CPU timer is not too large) and 400 samples to collect statistics on timings. On gaea c5 this takes about 10 seconds. - The results are written to stdout in json. - Added placeholder build and run of timing_tests to GH workflow. - Enabled for [push,pull_request] - We probably will not be able to use timings from GH but I still want to exercise the code we know the timing programs aren't broken by a commit. -

Local variables From 753cab308dc6d87bd17dd4df3f95664158c2deec Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Tue, 7 Nov 2023 08:29:43 -0500 Subject: [PATCH 0907/1329] +Refactor ALE_remap_velocities Refactored ALE_remap_velocities to separate the code setting the thicknesses at velocity points from the code that actually does the remapping. This includes the creation of the new public routines ALE_remap_set_h_vel and ALE_remap_set_h_vel_via_dz and the replacement the pair of tracer point thickness arguments to ALE_remap_velocities and remap_dyn_split_RK2_aux_vars with a pair of the old and new thicknesses at the velocity points and the elimination of several arguments to these routines that are no longer being used. There are also new internal routines ALE_remap_set_h_vel_partial and ALE_remap_set_h_vel_OBC to apply modifications to the velocity point thicknesses with OBCs and one runtime option. The runtime variable REMAP_UV_USING_OLD_ALG has effectively been moved from MOM_ALE.F90 to MOM.F90, although it is still being read in MOM_ALE_init for use with the accelerated regridding during initialization. All answers are bitwise identical, but there are two new public interfaces and changes to the arguments to two other public interfaces and a run-time parameter was moved between modules resulting in changes to some MOM_parameter_doc files. --- src/ALE/MOM_ALE.F90 | 381 +++++++++++++++++++--------- src/core/MOM.F90 | 58 ++++- src/core/MOM_dynamics_split_RK2.F90 | 27 +- 3 files changed, 335 insertions(+), 131 deletions(-) diff --git a/src/ALE/MOM_ALE.F90 b/src/ALE/MOM_ALE.F90 index e1c8e6911e..77ee1192a2 100644 --- a/src/ALE/MOM_ALE.F90 +++ b/src/ALE/MOM_ALE.F90 @@ -129,6 +129,7 @@ module MOM_ALE public ALE_remap_scalar public ALE_remap_tracers public ALE_remap_velocities +public ALE_remap_set_h_vel, ALE_remap_set_h_vel_via_dz public ALE_remap_interface_vals public ALE_remap_vertex_vals public ALE_PLM_edge_values @@ -597,6 +598,15 @@ subroutine ALE_regrid_accelerated(CS, G, GV, US, h, tv, n_itt, u, v, OBC, Reg, d real, dimension(SZI_(G),SZJ_(G),SZK_(GV)) :: h_orig !

After a recent commit, the value of OBC%debug was not being set and was being left in an indeterminate whenever DEBUG_OBC=False or DEBUG=False and DEBUG_OBC was unspecified. This would lead to the model writing out a number of checksums in some cases with open boundary conditions enabled, depending on what value was inherited by the uninitialized OBC%debug. Although this does not change any answers, it will avoid a problem that will write out a large volume of undesired output and greatly slow down configurations with open boundary conditions. --- src/core/MOM_open_boundary.F90 | 21 +++++++++------------ 1 file changed, 9 insertions(+), 12 deletions(-) diff --git a/src/core/MOM_open_boundary.F90 b/src/core/MOM_open_boundary.F90 index 5cf7c92fe9..7bfb6479b2 100644 --- a/src/core/MOM_open_boundary.F90 +++ b/src/core/MOM_open_boundary.F90 @@ -426,7 +426,7 @@ subroutine open_boundary_config(G, US, param_file, OBC) !

Continuity_fluxes is overloaded to provide either the layer thickness fluxes or the vertically summed barotropic fluxes. As a part of this change, the LB arguments to meridional_mass_flux and zonal_mass_flux were made optional and moved toward the end of the list of arguments. The intent of the ocean_grid_type argument to 11 routines in the continuity_PPM module was changed from inout to in. Missing factors of por_face_area[UV] were also added to merid_face_thickness and zonal_face_thickness when the visc_rem arguments are not present or where OBCs are in use. This could change answers, but it seems very unlikely that any impacted cases are in use yet. Answers are bitwise identical all known cases, but there are 4 new public interfaces, and some bugs were fixed in cases that are not likely in use yet. --- src/core/MOM_continuity.F90 | 192 ++++++++++++++++++++++++++++++-- src/core/MOM_continuity_PPM.F90 | 89 +++++++++------ 2 files changed, 239 insertions(+), 42 deletions(-) diff --git a/src/core/MOM_continuity.F90 b/src/core/MOM_continuity.F90 index 76e1bbc623..7a833ccb5c 100644 --- a/src/core/MOM_continuity.F90 +++ b/src/core/MOM_continuity.F90 @@ -3,8 +3,8 @@ module MOM_continuity !

As a part of these changes, the runtime parameter CONTINUITY_SCHEME was obsoleted with a warning value of "PPM". All answers are bitwise identical, and all public interfaces look the same from the outside, but there is one fewer entry in the MOM_parameter_doc.all files. --- src/core/MOM_continuity.F90 | 181 +++--------------------- src/diagnostics/MOM_obsolete_params.F90 | 3 +- 2 files changed, 19 insertions(+), 165 deletions(-) diff --git a/src/core/MOM_continuity.F90 b/src/core/MOM_continuity.F90 index 7a833ccb5c..44422d5e47 100644 --- a/src/core/MOM_continuity.F90 +++ b/src/core/MOM_continuity.F90 @@ -3,13 +3,12 @@ module MOM_continuity !

This commit also renames a number of internal edge thickness variables from h_L and h_R to h_S and h_N or h_W and h_E for greater clarity, since left and right are not so well defined on the grid as north, south, east and west. All answers are bitwise identical, but there are 4 new publicly visible interfaces. --- src/core/MOM_continuity_PPM.F90 | 431 ++++++++++++++++++-------------- 1 file changed, 250 insertions(+), 181 deletions(-) diff --git a/src/core/MOM_continuity_PPM.F90 b/src/core/MOM_continuity_PPM.F90 index 7f96e675cd..415d04dd36 100644 --- a/src/core/MOM_continuity_PPM.F90 +++ b/src/core/MOM_continuity_PPM.F90 @@ -20,6 +20,8 @@ module MOM_continuity_PPM public continuity_PPM, continuity_PPM_init, continuity_PPM_stencil public zonal_mass_flux, meridional_mass_flux +public zonal_flux_thickness, meridional_flux_thickness +public zonal_edge_thickness, meridional_edge_thickness !>@{ CPU time clock IDs integer :: id_clock_update, id_clock_correct @@ -142,7 +144,7 @@ subroutine continuity_PPM(u, v, hin, h, uh, vh, dt, G, GV, US, CS, OBC, pbv, uhb "MOM_continuity_PPM: Either both visc_rem_u and visc_rem_v or neither"// & " one must be present in call to continuity_PPM.") - stencil = 3 ; if (CS%simple_2nd) stencil = 2 ; if (CS%upwind_1st) stencil = 1 + stencil = continuity_PPM_stencil(CS) if (x_first) then !

As a part of this, there are new edge thickness arguments to zonal_mass_flux and meridional_mass_flux. The interfaces to zonal_edge_thickness and meridional_edge_thickness are new publicly visible and are used in MOM_continuity. This commits also changes the name of the loop_bounds_type to cont_loop_bounds_type and makes it public but opaque adds the publicly visible function set_continuity_loop_bounds to enable the continuity loop bounds to be set from outside of the continuity_PPM module. Reflecting these changes there are new calls to zonal_edge_thickness and meridional_edge_thickness in the 3 routines in MOM_continuity and in continuity_PPM, and new arrays for holding the edge thicknesses in these routines. All answers are bitwise identical, but there are new publicly visible interfaces and types and changes to other publicly visible interfaces. However, no changes are required outside of MOM_continuity and MOM_continuity_PPM. --- src/core/MOM_continuity.F90 | 39 ++++-- src/core/MOM_continuity_PPM.F90 | 231 ++++++++++++++++++-------------- 2 files changed, 156 insertions(+), 114 deletions(-) diff --git a/src/core/MOM_continuity.F90 b/src/core/MOM_continuity.F90 index 44422d5e47..116bf8f195 100644 --- a/src/core/MOM_continuity.F90 +++ b/src/core/MOM_continuity.F90 @@ -7,6 +7,7 @@ module MOM_continuity use MOM_continuity_PPM, only : continuity_stencil=>continuity_PPM_stencil use MOM_continuity_PPM, only : continuity_init=>continuity_PPM_init use MOM_continuity_PPM, only : continuity_CS=>continuity_PPM_CS +use MOM_continuity_PPM, only : zonal_edge_thickness, meridional_edge_thickness use MOM_continuity_PPM, only : zonal_mass_flux, meridional_mass_flux use MOM_diag_mediator, only : time_type use MOM_grid, only : ocean_grid_type @@ -56,9 +57,17 @@ subroutine continuity_3d_fluxes(u, v, h, uh, vh, dt, G, GV, US, CS, OBC, pbv) type(ocean_OBC_type), pointer :: OBC !< Open boundaries control structure. type(porous_barrier_type), intent(in) :: pbv !< porous barrier fractional cell metrics - call zonal_mass_flux(u, h, uh, dt, G, GV, US, CS, OBC, pbv%por_face_areaU) + !

Also cleaned up and simplified the logic of some of the flags used to apply specified open boundary conditions, adding a new 1-d logical array thereby avoiding working unnecessarily on some loops or repeatedly checking for specified open boundary condition points. Two openMP directives were also simplified. All answers are bitwise identical, but there are new optional arguments to three publicly visible routines. --- src/core/MOM_continuity_PPM.F90 | 172 +++++++++++++++++--------------- 1 file changed, 91 insertions(+), 81 deletions(-) diff --git a/src/core/MOM_continuity_PPM.F90 b/src/core/MOM_continuity_PPM.F90 index be2dabd9e6..ba8c234bc2 100644 --- a/src/core/MOM_continuity_PPM.F90 +++ b/src/core/MOM_continuity_PPM.F90 @@ -84,7 +84,7 @@ module MOM_continuity_PPM !> Time steps the layer thicknesses, using a monotonically limit, directionally split PPM scheme, !! based on Lin (1994). subroutine continuity_PPM(u, v, hin, h, uh, vh, dt, G, GV, US, CS, OBC, pbv, uhbt, vhbt, & - visc_rem_u, visc_rem_v, u_cor, v_cor, BT_cont) + visc_rem_u, visc_rem_v, u_cor, v_cor, BT_cont, du_cor, dv_cor) type(ocean_grid_type), intent(in) :: G !< The ocean's grid structure. type(verticalGrid_type), intent(in) :: GV !< Vertical grid structure. real, dimension(SZIB_(G),SZJ_(G),SZK_(GV)), & @@ -133,6 +133,12 @@ subroutine continuity_PPM(u, v, hin, h, uh, vh, dt, G, GV, US, CS, OBC, pbv, uhb !! transport [L T-1 ~> m s-1]. type(BT_cont_type), optional, pointer :: BT_cont !< A structure with elements that describe !! the effective open face areas as a function of barotropic flow. + real, dimension(SZIB_(G),SZJ_(G)), & + optional, intent(out) :: du_cor !< The zonal velocity increments from u that give uhbt + !! as the depth-integrated transports [L T-1 ~> m s-1]. + real, dimension(SZI_(G),SZJB_(G)), & + optional, intent(out) :: dv_cor !< The meridional velocity increments from v that give vhbt + !! as the depth-integrated transports [L T-1 ~> m s-1]. !

The following preprocessing commands are handled: * #define / #undef * #ifdef / #else / #endif A new flag is added to provide defined macros (-D), and is chosen to match the `cpp` flag, so that flags can be shared across programs. Macros are tracked in a new internal variable and are used for #ifdef testing. Nested condition blocks are supported by using an internal stack of the exclusion state. Certain cases are still not handled. * #if blocks containing logical expressions are not parsed. * CPP content inside of #include is ignored. No doubt many other cases are still unconsidered, such as exotic macro names. The autoconf builds use this feature by passing the generated $(DEFS) argument to makedep. This is suitable for now, but we may need to consider two cases in the future: * Macros defined in $CPPFLAGS are currently ignored, and perhaps they should be included here. The risk is that it may contain non-macro flags. * At some point, DEFS could be moved to a config.h file, and DEFS would no longer contain these macros. (Note that this is very unlikely at the moment, since this feature only works with C.) --- ac/Makefile.in | 3 +- ac/makedep | 93 +++++++++++++++++++++++++++++++++++++++++++++++--- 2 files changed, 89 insertions(+), 7 deletions(-) diff --git a/ac/Makefile.in b/ac/Makefile.in index 64a60e70d1..c4d23efdfb 100644 --- a/ac/Makefile.in +++ b/ac/Makefile.in @@ -19,7 +19,6 @@ SRC_DIRS = @SRC_DIRS@ -include Makefile.dep - # Generate Makefile from template Makefile: @srcdir@/ac/Makefile.in config.status ./config.status @@ -33,7 +32,7 @@ rwildcard=$(foreach d,$(wildcard $(1:=/*)),$(call rwildcard,$d,$2) $(filter $(su .PHONY: depend depend: Makefile.dep Makefile.dep: $(MAKEDEP) $(call rwildcard,$(SRC_DIRS),*.h *.c *.inc *.F90) - $(PYTHON) $(MAKEDEP) -o Makefile.dep -e $(SRC_DIRS) + $(PYTHON) $(MAKEDEP) $(DEFS) -o Makefile.dep -e $(SRC_DIRS) # Delete any files associated with configuration (including the Makefile). diff --git a/ac/makedep b/ac/makedep index 99c2ef6ce6..e37f35aca5 100755 --- a/ac/makedep +++ b/ac/makedep @@ -13,9 +13,16 @@ import sys # Pre-compile re searches re_module = re.compile(r"^ *module +([a-z_0-9]+)") re_use = re.compile(r"^ *use +([a-z_0-9]+)") +re_cpp_define = re.compile(r"^ *# *define +[_a-zA-Z][_a-zA-Z0-9]") +re_cpp_undef = re.compile(r"^ *# *undef +[_a-zA-Z][_a-zA-Z0-9]") +re_cpp_ifdef = re.compile(r"^ *# *ifdef +[_a-zA-Z][_a-zA-Z0-9]") +re_cpp_ifndef = re.compile(r"^ *# *ifndef +[_a-zA-Z][_a-zA-Z0-9]") +re_cpp_if = re.compile(r"^ *# *if +") +re_cpp_else = re.compile(r"^ *# *else") +re_cpp_endif = re.compile(r"^ *# *endif") re_cpp_include = re.compile(r"^ *# *include *[<\"']([a-zA-Z_0-9\.]+)[>\"']") re_f90_include = re.compile(r"^ *include +[\"']([a-zA-Z_0-9\.]+)[\"']") -re_program = re.compile(r"^ *[pP][rR][oO][gG][rR][aA][mM] +([a-zA-Z_0-9]+)") +re_program = re.compile(r"^ *program +([a-z_0-9]+)", re.IGNORECASE) re_end = re.compile(r"^ *end *(module|procedure) ", re.IGNORECASE) # NOTE: This excludes comments and tokens with substrings containing `function` # or `subroutine`, but will fail if the keywords appear in other contexts. @@ -26,7 +33,7 @@ re_procedure = re.compile( def create_deps(src_dirs, skip_dirs, makefile, debug, exec_target, fc_rule, - link_externals, script_path): + link_externals, defines): """Create "makefile" after scanning "src_dis".""" # Scan everything Fortran related @@ -66,7 +73,7 @@ def create_deps(src_dirs, skip_dirs, makefile, debug, exec_target, fc_rule, o2mods, o2uses, o2h, o2inc, o2prg, prg2o, mod2o = {}, {}, {}, {}, {}, {}, {} externals, all_modules = [], [] for f in F90_files: - mods, used, cpp, inc, prg, has_externals = scan_fortran_file(f) + mods, used, cpp, inc, prg, has_externals = scan_fortran_file(f, defines) # maps object file to modules produced o2mods[object_file(f)] = mods # maps module produced to object file @@ -272,10 +279,16 @@ def nested_inc(inc_files, f2F): return inc_files + sorted(set(hlst)), used_mods -def scan_fortran_file(src_file): +def scan_fortran_file(src_file, defines=None): """Scan the Fortran file "src_file" and return lists of module defined, module used, and files included.""" module_decl, used_modules, cpp_includes, f90_includes, programs = [], [], [], [], [] + + cpp_defines = defines if defines is not None else [] + + cpp_macros = [define.split('=')[0] for define in cpp_defines] + cpp_group_stack = [] + with io.open(src_file, 'r', errors='replace') as file: lines = file.readlines() @@ -285,7 +298,72 @@ def scan_fortran_file(src_file): file_has_externals = False # True if the file contains any external objects + cpp_exclude = False + # True if the parser excludes the subsequent lines + + cpp_group_stack = [] + # Stack of condition group exclusion states + for line in lines: + # Start of #ifdef condition group + match = re_cpp_ifdef.match(line) + if match: + cpp_group_stack.append(cpp_exclude) + + # If outer group is excluding or macro is missing, then exclude + macro = line.lstrip()[1:].split()[1] + cpp_exclude = cpp_exclude or macro not in cpp_macros + + # Start of #ifndef condition group + match = re_cpp_ifndef.match(line) + if match: + cpp_group_stack.append(cpp_exclude) + + # If outer group is excluding or macro is present, then exclude + macro = line.lstrip()[1:].split()[1] + cpp_exclude = cpp_exclude or macro in cpp_macros + + # Start of #if condition group + match = re_cpp_if.match(line) + if match: + cpp_group_stack.append(cpp_exclude) + + # XXX: Don't attempt to parse #if statements, but store the state. + # if/endif stack.

The GitHub Actions CI nodes would randomly select either 1.14.2 or 1.14.3, and would raise an FPE error if 1.14.3 was selected. Additionally, the homebrew installation does not provide a clean method for selecting a different version of HDF5. Thus, for now we disable FPEs in the MacOS testing, and hope to catch any legitimate FP errors in the Ubuntu version. We will restore these tests as soon as this has been fixed in an easily-accessible version of HDF5.

From 7ddc727a2460784ea048e511d66dfa207c0a408e Mon Sep 17 00:00:00 2001 From: alex-huth Date: Mon, 27 Nov 2023 18:15:46 -0500 Subject: [PATCH 0929/1329] This commit guarantees consistency of the ice sheet code under rotated/flipped input and grids, and under dimensional rescaling to the +/-140 power. Bitwise identical results were achieved under rotation/rescaling using standard 2D test cases such as MISMIP+. Major changes include the following: - Specified order of operations throughout, and modified the implementation of FEM integration, h-point-to-node operations, etc for consistency under rotation (see MOM_ice_shelf_dynamics.F90 subroutines calc_shelf_driving_stress, CG_action, CG_action_subgrid_basal, matrix_diagonal, shelf_advance_front, and interpolate_h_to_b). - Added an ice-shelf version of 'first_direction' and 'alterate_first_direction', allowing users to control the order in which the x- and y-direction ice-shelf advection calls are made. Required for consistency under rotation. - Dimensional rescaling fixes throughout MOM_ice_shelf_initialize.F90, and within MOM_ice_shelf_dynamics.F90 (see subroutines initialize_ice_shelf_dyn, ice_shelf_solve_outer, and calc_shelf_taub) - Rotation/rescaling testing revealed two additional bugs that were subsequently fixed: (1) An index error in the conjugate gradient algorithm (subroutine CG_action) (2) Discretization error for the east/north fluxes in subroutines ice_shelf_advect_thickness_x and ice_shelf_advect_thickness_y. The commit also includes several simple changes for code readability and computational efficiency: - Saved Phi, PhiC, and Phisub in the ice shelf dynamics control structure at the start of each run, rather than reallocating and recalculating these static fields each time they are used. Reshaped the Phisub array for computational efficiency over loops. - Modified the sub-cell grounding scheme so that it is only called for partially-grounded cells that contain the grounding line (i.e. where float_cond(i,j)==1). Added float_cond to the ice dynamics structure for output. - Simplified the option to calculate ice viscosity at 4 quadrature points per cell rather than at cell centers, by adding parameter NUMBER_OF_ICE_VISCOSITY_QUADRATURE_POINTS and reshaping CS%ice_visc accordingly. - Style changes and removal of unused code (e.g. removed subroutine apply_boundary_values and field thickness_bdry_val) --- src/ice_shelf/MOM_ice_shelf_dynamics.F90 | 1180 ++++++++++---------- src/ice_shelf/MOM_ice_shelf_initialize.F90 | 58 +- 2 files changed, 620 insertions(+), 618 deletions(-) diff --git a/src/ice_shelf/MOM_ice_shelf_dynamics.F90 b/src/ice_shelf/MOM_ice_shelf_dynamics.F90 index 312fa43fe9..4bfcc3605c 100644 --- a/src/ice_shelf/MOM_ice_shelf_dynamics.F90 +++ b/src/ice_shelf/MOM_ice_shelf_dynamics.F90 @@ -84,12 +84,11 @@ module MOM_ice_shelf_dynamics real, pointer, dimension(:,:) :: t_shelf => NULL() !< Vertically integrated temperature in the ice shelf/stream, !! on corner-points (B grid) [C ~> degC] real, pointer, dimension(:,:) :: tmask => NULL() !< A mask on tracer points that is 1 where there is ice. - real, pointer, dimension(:,:) :: ice_visc => NULL() !< Glen's law ice viscosity (Pa s), + real, pointer, dimension(:,:,:) :: ice_visc => NULL() !< Glen's law ice viscosity (Pa s), !! in [R L2 T-1 ~> kg m-1 s-1]. - real, pointer, dimension(:,:,:) :: Ee => NULL() !< Glen's effective strain-rate ** (1-n)/(n) + !! at either 1 (cell-centered) or 4 quadrature points per cell real, pointer, dimension(:,:) :: AGlen_visc => NULL() !< Ice-stiffness parameter in Glen's law ice viscosity, !! often in [Pa-3 s-1] if n_Glen is 3. - real, pointer, dimension(:,:) :: thickness_bdry_val => NULL() !< The ice thickness at an inflowing boundary [Z ~> m]. real, pointer, dimension(:,:) :: u_bdry_val => NULL() !< The zonal ice velocity at inflowing boundaries !!

The GitHub Actions CI nodes would randomly select either 1.14.2 or 1.14.3, and would raise an FPE error if 1.14.3 was selected. Additionally, the homebrew installation does not provide a clean method for selecting a different version of HDF5. Thus, for now we disable FPEs in the MacOS testing, and hope to catch any legitimate FP errors in the Ubuntu version. We will restore these tests as soon as this has been fixed in an easily-accessible version of HDF5. As part of this PR, I have also moved the FCFLAGS configuration to the platform specific Actions files, allowing for independent compiler configuration for each platform. --------- Co-authored-by: Marshall Ward --- .github/actions/macos-setup/action.yml | 15 + .github/actions/testing-setup/action.yml | 11 - .github/actions/ubuntu-setup/action.yml | 12 + config_src/drivers/nuopc_cap/mom_cap.F90 | 138 ++++++-- .../drivers/nuopc_cap/mom_cap_methods.F90 | 9 +- config_src/infra/FMS1/MOM_domain_infra.F90 | 15 +- config_src/infra/FMS2/MOM_coms_infra.F90 | 10 + config_src/infra/FMS2/MOM_domain_infra.F90 | 17 +- src/core/MOM.F90 | 4 +- src/framework/MOM_domains.F90 | 321 +++++++++++++++++- src/ice_shelf/MOM_ice_shelf.F90 | 2 +- src/ocean_data_assim/MOM_oda_driver.F90 | 2 +- 12 files changed, 497 insertions(+), 59 deletions(-) diff --git a/.github/actions/macos-setup/action.yml b/.github/actions/macos-setup/action.yml index fecbe787b5..4c248abd11 100644 --- a/.github/actions/macos-setup/action.yml +++ b/.github/actions/macos-setup/action.yml @@ -16,3 +16,18 @@ runs: brew install netcdf-fortran brew install mpich echo "::endgroup::" + + # NOTE: Floating point exceptions are currently disabled due to an error in + # HDF5 1.4.3.

This file time steps the adiabatic dynamic core by splitting +!! between baroclinic and barotropic modes. It uses a pseudo-second order +!! Runge-Kutta time stepping scheme for the baroclinic momentum +!! equation and a forward-backward coupling between the baroclinic +!! momentum and continuity equations. This split time-stepping +!! scheme is described in detail in Hallberg (JCP, 1997). Additional +!! issues related to exact tracer conservation and how to +!! ensure consistency between the barotropic and layered estimates +!! of the free surface height are described in Hallberg and +!! Adcroft (Ocean Modelling, 2009). This was the time stepping code +!! that is used for most GOLD applications, including GFDL's ESM2G +!! Earth system model, and all of the examples provided with the +!! MOM code (although several of these solutions are routinely +!! verified by comparison with the slower unsplit schemes). +!! +!! The subroutine step_MOM_dyn_split_RK2b actually does the time +!! stepping, while register_restarts_dyn_split_RK2b sets the fields +!! that are found in a full restart file with this scheme, and +!! initialize_dyn_split_RK2b initializes the cpu clocks that are +!! used in this module.

As a part of this change, the continuity solver is used to find the thickness fluxes used in the predictor step Coriolis terms, and the horizontal viscous accelerations are calculated for both the predictor and corrector steps, thereby avoiding the need to vertically remap any 3-d fields apart from a single pair of velocity components. The run-time option STORE_CORIOLIS_ACCEL is no longer used when SPLIT_RK2B = True. FPMIX was also disabled in this mode due to unresolved dimensional inconsistency errors in that code. Additionally, the time-filtered velocities are now used instead of the instantaneous velocities in the second call to radiation_open_bdry_conds(), which should improve the performance of several of the Orlanski-type open boundary conditions. The 2-d fields du_av_inst and dv_av_inst were added to the restart file, while the 3-d fields u2, v2, diffu and diffv and either CAu and CAv or uh, vh and h2 are all removed from the restart files. Remap_dyn_split_RK2b_aux_vars() now has nothing to do, and it should probably be eliminated altogether in a subsequent commit. All answers are changed when SPLIT_RK2B = True, and there are changes to the contents of the restart files. --- src/core/MOM_dynamics_split_RK2b.F90 | 417 +++++++++++---------------- 1 file changed, 162 insertions(+), 255 deletions(-) diff --git a/src/core/MOM_dynamics_split_RK2b.F90 b/src/core/MOM_dynamics_split_RK2b.F90 index a289014313..9cd8fbfc09 100644 --- a/src/core/MOM_dynamics_split_RK2b.F90 +++ b/src/core/MOM_dynamics_split_RK2b.F90 @@ -141,6 +141,12 @@ module MOM_dynamics_split_RK2b real ALLOCABLE_, dimension(NIMEM_,NJMEM_,NKMEM_) :: pbce !< pbce times eta gives the baroclinic pressure !! anomaly in each layer due to free surface height !! anomalies [L2 H-1 T-2 ~> m s-2 or m4 kg-1 s-2]. + real ALLOCABLE_, dimension(NIMEMB_PTR_,NJMEM_) :: du_av_inst !< The barotropic zonal velocity increment + !! between filtered and instantaneous velocities + !!

Separately, cuberoot was tested by replacing expressions like A**(1./3.) with cuberoot(A) in MOM_energetic_PBL and verifying that the answers only change at roundoff, but that it can give bitwise identical results when the argument is scaled by an integer power of 8 and then unscaled by the corresponding integer power of 2, but that change will occur in a subsequent commit as it can change answers depending on an ANSWER_DATE flag.

This appears to produce a ~2.5x speedup of the solver, reducing its time from embarassingly slow to disappointingly slow. It is slightly faster than the GNU cbrt function, but still about 3x slower than the Intel SVML cbrt function. Timings (s) (16M array, -O3 -mavx -mfma) | Solver | -O2 | -O3 | |---------------------|-------|-------| | GNU x**1/3 | 0.225 | 0.198 | | GNU cuberoot before | 0.418 | 0.412 | | GNU cuberoot after | 0.208 | 0.187 | | Intel x**1/3 | 0.068 | 0.067 | | Intel before | 0.514 | 0.507 | | Intel after | 0.213 | 0.189 | At least one issue here is that Intel SVML is using fast vectorized logic operators whereas the Fortran intrinsics are replaced with slower legacy scalar versions. Not sure there is much we could even do about that without complaining to vendors. Also, I'm sure there's magic in their solvers which we are not capturing. Regardless, I think this is a major improvement. I do not believe it will change answers, but probably a good idea to verify this and get it in before committing any solutions using cuberoot(). --- src/framework/MOM_intrinsic_functions.F90 | 104 ++++++++++++++++++++-- 1 file changed, 98 insertions(+), 6 deletions(-) diff --git a/src/framework/MOM_intrinsic_functions.F90 b/src/framework/MOM_intrinsic_functions.F90 index 4327cfa5a6..5d420057d4 100644 --- a/src/framework/MOM_intrinsic_functions.F90 +++ b/src/framework/MOM_intrinsic_functions.F90 @@ -5,6 +5,7 @@ module MOM_intrinsic_functions !

This could dangerously expose them to other functions, but it prevents multiple definitions of the same numbers. * The exponent is now cube-rooted in rescale rather than descale. * The exponent expressions are broken into more explicit steps, rather than combining multiple steps and assumptions into a single expression. * The bias is no longer assumed to be a multiple of three. This is true for double precision but not single precision. A new test of quasi-random number was also added to the cuberoot test suite. These numbers were able to detect the differences in GNU and Intel compiler output. A potential error in the return value of the test was also fixed. The volatile test of 1 - 0.5*ULP has been added. The cube root of this value rounds to 1, and needs to be handled carefully. The unit test function `cuberoot(v**3)` was reversed to `cuberoot(v)**`, to include testing of this value.

To help make use of this new capability, this commit also adds the new functions set_h_neglect and set_dz_neglect to the MOM_regridding module. build_grid_rho and build_grid_HyCOM1 have been refactored to use set_h_neglect in place of the corresponding duplicated code blocks. This commit also adds the new optional argument h_in_Z_units to MOM_initialize_tracer_from_Z, which in turn uses this new capability for ALE_remap_scalar to use vertical layer extents (in Z units) rather than thicknesses (in H units). Although there are new optional arguments to public interfaces, they are not yet being exercised with this commit so no answers are changed. Moreover, even if they were being exercised, all Boussinesq solutions would give identical answers. --- src/ALE/MOM_ALE.F90 | 36 +++++++---- src/ALE/MOM_regridding.F90 | 60 ++++++++++++++----- .../MOM_tracer_initialization_from_Z.F90 | 56 +++++++++++------ 3 files changed, 108 insertions(+), 44 deletions(-) diff --git a/src/ALE/MOM_ALE.F90 b/src/ALE/MOM_ALE.F90 index 77ee1192a2..543d77a0f3 100644 --- a/src/ALE/MOM_ALE.F90 +++ b/src/ALE/MOM_ALE.F90 @@ -1260,16 +1260,17 @@ end subroutine mask_near_bottom_vel !! h_dst must be dimensioned as a model array with GV%ke layers while h_src can !! have an arbitrary number of layers specified by nk_src. subroutine ALE_remap_scalar(CS, G, GV, nk_src, h_src, s_src, h_dst, s_dst, all_cells, old_remap, & - answers_2018, answer_date ) + answers_2018, answer_date, h_neglect, h_neglect_edge) type(remapping_CS), intent(in) :: CS !< Remapping control structure type(ocean_grid_type), intent(in) :: G !< Ocean grid structure type(verticalGrid_type), intent(in) :: GV !< Ocean vertical grid structure integer, intent(in) :: nk_src !< Number of levels on source grid real, dimension(SZI_(G),SZJ_(G),nk_src), intent(in) :: h_src !< Level thickness of source grid - !!

The previous approach inappropriately used an simple multiplicative rescaling (via a call to dz_to_thickness_simple in MOM_initialize_tracer_from_Z) by a factor that includes the Boussinesq reference density when in non-Boussinesq mode. A new thermo_vars_type arguments was added to initialize_MOM_generic_tracer to allow for this change. Also revised MOM_generic_tracer_column_physics to use thickness_to_dz instead of a simple multiplicative rescaling to get the layer vertical extents (in m) that are used in calls to generic_tracer_source. The multiplicative factor that was used previously (GV%H_to_m) includes the Boussinesq reference density and hence is inappropriate in non-Boussinesq mode; using thickness_to_dz avoids this. Also added comments documenting the meaning and units of about 30 real variables in the MOM_generic_tracer routines. There is a new mandatory argument to initialize_MOM_generic_tracer. All Boussinseq mode answers are bitwise identical, but in non-Boussinesq mode mode generic tracer answers are changed by avoiding the use of the Boussinesq reference density in several places. --- src/tracer/MOM_generic_tracer.F90 | 144 ++++++++++++++----------- src/tracer/MOM_tracer_flow_control.F90 | 2 +- 2 files changed, 84 insertions(+), 62 deletions(-) diff --git a/src/tracer/MOM_generic_tracer.F90 b/src/tracer/MOM_generic_tracer.F90 index 131110e6b2..7f550d8de5 100644 --- a/src/tracer/MOM_generic_tracer.F90 +++ b/src/tracer/MOM_generic_tracer.F90 @@ -38,6 +38,7 @@ module MOM_generic_tracer use MOM_forcing_type, only : forcing, optics_type use MOM_grid, only : ocean_grid_type use MOM_hor_index, only : hor_index_type + use MOM_interface_heights, only : thickness_to_dz use MOM_io, only : file_exists, MOM_read_data, slasher use MOM_open_boundary, only : ocean_OBC_type use MOM_open_boundary, only : register_obgc_segments, fill_obgc_segments @@ -75,8 +76,10 @@ module MOM_generic_tracer character(len = 200) :: IC_file !< The file in which the generic tracer initial values can !! be found, or an empty string for internal initialization. logical :: Z_IC_file !< If true, the generic_tracer IC_file is in Z-space.

In addition, the refactoring associated with this change explicitly revealed that as it was implemented it introduced an undesirable dependency on the value of the Boussinesq reference density, RHO_0, when in non-Boussinesq mode. To avoid this, a new version of the Bodner u'w' calculation was introduced in fully non-Boussinesq mode, which does change answers with this combination; because there is not yet a known case that used this combination, we have chosen not to add a runtime parameter to preserve the old answers when the Bodner parameterization is used in fully-Boussinesq mode. This change will modify the contents of some MOM_parameter_doc files with USE_BODNER=True, and it changes answers in cases that are also fully non-Boussinesq. The new runtime parameter ML_RESTRAT_ANSWER_DATE might need to be set below 20240201 to retain some existing Boussinesq answers. --- .../lateral/MOM_mixed_layer_restrat.F90 | 99 ++++++++++++++----- 1 file changed, 74 insertions(+), 25 deletions(-) diff --git a/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 b/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 index 36a83cd43a..c10a55309b 100644 --- a/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 +++ b/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 @@ -14,6 +14,7 @@ module MOM_mixed_layer_restrat use MOM_forcing_type, only : mech_forcing, find_ustar use MOM_grid, only : ocean_grid_type use MOM_hor_index, only : hor_index_type +use MOM_intrinsic_functions, only : cuberoot use MOM_lateral_mixing_coeffs, only : VarMix_CS use MOM_restart, only : register_restart_field, query_initialized, MOM_restart_CS use MOM_unit_scaling, only : unit_scale_type @@ -67,7 +68,7 @@ module MOM_mixed_layer_restrat real :: nstar !< The n* value used to estimate the turbulent vertical momentum flux [nondim] real :: min_wstar2 !< The minimum lower bound to apply to the vertical momentum flux, !! w'u', in the Bodner et al., restratification parameterization - !!

This unavoidably requires u at js-3 and v at is-3, which are unavailable. It also requires Del omega at Ieq+1 and Jeq+1, which requires v at Ieq+3 and u at Jeq+3, which are unavailable. This necessitates a halo update. Fixes several bugs in Leith+E. - Fixes indexing when computing smoothed vorticity and its gradient - Crucially, computes `vert_vort_mag` when using Leith+E - Fixes some logic in the smoothing code - Other minor indexing fixes * Leith+E Logic Update Ah is required at h and q points. The original code computed Ah at h points, then packed into Ah_h, then applied upper bounds to Ah. If Ah_h is in the diag_table or if debug is true, then the value of Ah with upper bounds get packed into Ah_h. Then, at q points the code unpacks Ah_h. This update makes sure that the upper bound gets applied to q points, not just h points. * Leith+E halo updates The main thing that this commit does is to perform smoothing of u and v outside of the loop over layers. This swaps nz 2D blocking halo updates for a single blocking 3D halo update. * Leith+E smoothing This commit adds a runtime flag, SMOOTH_AH. If True (default) then `m_leithy` and `Ah` are both smoothed, which leads to many blocking communications. If False then these fields are rougher, but there is less communication. * Leith+E eliminate pass-var This commit removes one halo update in Leith+E. To achieve this requires re-indexing two assignments. The value of Ah and Kh are computed at h points, then re-used at q points. Without the halo update it is necessary to offset the assignment at h and q points, e.g. Kh(I,J) = Kh_h(i+1,j+1,k), to avoid accessing values that have not been computed. * Leith+E OBC Adds code so that Leith+E works with OBC. * Leith+E eliminate halo update This commit eliminates one more halo update in Leith+E. * *Correct rotational symmetry with USE_LEITHY This commit revises the smoothing code used when USE_LEITHY = True to give answers that respect rotational symmetry and it also corrects some horizontal indexing bugs and problems with the staggering in some halo update and smooth_x9 calls and reduces some loop ranges to their minimal required values. The specific changes include: 1. Corrected a horizontal indexing bug when interpolating Kh_h and Ah_h to corner (q) points when USE_LEITHY = True. These had previously been inappropriately copied from the thickness point to the southwest of the corner point. This required symmetric-memory-mode calculations of the thickness point viscosities whenever USE_LEITHY is true, but to avoid adding complicated logic, the symmetric-memory loop bounds are used for the calculation of Kh. 2. Revised smooth_x9 to give rotationally symmetric answers and split it into the two routines smooth_x9_h and smooth_x9_uv to reduce the memory used by this routine and reduce the use of optional arguments. 3. Eliminated 4 unneeded halo update calls, and added error handling for the case where Leith options are used with insufficiently wide halos. 4. Added new integers to indicate the loop ranges over which the viscosities and related variables should be calculated, depending on which options are active, and then adjusted 91 do-loop extents horizontal_viscosity code to reflect the loop ranges over which arrays are actually used. 5. Added a new 2-d variable for the squared viscosity for smoothing that can be used for halo updates and to avoid having a variable with confusingly inconsistent dimensions at various points in the code. 6. Corrected the position arguments on 2 smooth_x9 calls and 4 pass_var calls that are used when USE_LEITHY=.true. and SMOOTH_AH=.true. As previously written, these smooth_x9 and pass_var calls would work when in non-symmetric memory mode but would give incorrect answers when in symmetric memory mode. These revisions change answers when USE_LEITHY is true, but answers are bitwise identical in all other cases. --------- Co-authored-by: Robert Hallberg --- .../lateral/MOM_hor_visc.F90 | 565 ++++++++++-------- 1 file changed, 312 insertions(+), 253 deletions(-) diff --git a/src/parameterizations/lateral/MOM_hor_visc.F90 b/src/parameterizations/lateral/MOM_hor_visc.F90 index 5bd3809a85..4d57556d03 100644 --- a/src/parameterizations/lateral/MOM_hor_visc.F90 +++ b/src/parameterizations/lateral/MOM_hor_visc.F90 @@ -74,6 +74,8 @@ module MOM_hor_visc !!

The internal conversion in apply_ALE_sponge between layer thicknesses and layer vertical extents matches those in thickness_to_dz, and uses the layer-averaged specific volumes when in non-Boussinesq mode. As a part of these changes, 12 internal variables in MOM_ALE_sponge were renamed (e.g., from data_h to data_dz) to more clearly reflect that they are the layer vertical extents instead of thicknesses, and there are new 3-d variables dz_model, that is created from h when the sponges are applied to the velocities, and data_dz to handle the conversion of the input thicknesses or vertical extents in initialize_ALE_sponge_fixed. This commit includes adding a new thermo_var_type argument to apply_ALE_sponge, a new unit_scale_type argument to rotate_ALE_sponge and initialize_ALE_sponge_varying and the new optional argument data_h_is_Z to initialize_ALE_sponge_fixed to indicate that the in thicknesses arguments are vertical distances (in [Z ~> m]) and do not need to be rescaled inside of the ALE_sponge code, and similarly for the new optional argument data_h_in_Z to get_ALE_sponge_thicknesses. This commit also adds halo size and Omit_Corners arguments to the pass_var calls in the ALE_sponge code. There are new optional arguments to 2 publicly visible routines, and new mandatory arguments to 3 others, but by default the meaning and units of all previous arguments are the same, and answers will be bitwise identical in any Boussinesq cases. However, answers will change in any non-Boussinesq cases that use the ALE_sponges. --- src/core/MOM.F90 | 2 +- .../MOM_state_initialization.F90 | 14 +- .../vertical/MOM_ALE_sponge.F90 | 261 +++++++++++------- .../vertical/MOM_diabatic_driver.F90 | 4 +- 4 files changed, 167 insertions(+), 114 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 1922e87926..9d64b9bf17 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -2958,7 +2958,7 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, & endif if (associated(ALE_sponge_in_CSp)) then - call rotate_ALE_sponge(ALE_sponge_in_CSp, G_in, CS%ALE_sponge_CSp, G, GV, turns, param_file) + call rotate_ALE_sponge(ALE_sponge_in_CSp, G_in, CS%ALE_sponge_CSp, G, GV, US, turns, param_file) call update_ALE_sponge_field(CS%ALE_sponge_CSp, T_in, G, GV, CS%T) call update_ALE_sponge_field(CS%ALE_sponge_CSp, S_in, G, GV, CS%S) endif diff --git a/src/initialization/MOM_state_initialization.F90 b/src/initialization/MOM_state_initialization.F90 index 855a6f2aa0..0bd155e8e4 100644 --- a/src/initialization/MOM_state_initialization.F90 +++ b/src/initialization/MOM_state_initialization.F90 @@ -2074,9 +2074,9 @@ subroutine initialize_sponges_file(G, GV, US, use_temperature, tv, u, v, depth_t ! else !

By default all answers are bitwise identical, but when this new option is exercised, answers could change at roundoff for some non-Boussinesq cases. --- src/tracer/MOM_tracer_Z_init.F90 | 89 +++++++++++++++++++------------- 1 file changed, 54 insertions(+), 35 deletions(-) diff --git a/src/tracer/MOM_tracer_Z_init.F90 b/src/tracer/MOM_tracer_Z_init.F90 index c404c560f3..2cf0ba1efe 100644 --- a/src/tracer/MOM_tracer_Z_init.F90 +++ b/src/tracer/MOM_tracer_Z_init.F90 @@ -27,50 +27,58 @@ module MOM_tracer_Z_init !> This function initializes a tracer by reading a Z-space file, returning !! .true. if this appears to have been successful, and false otherwise. -function tracer_Z_init(tr, h, filename, tr_name, G, GV, US, missing_val, land_val) +function tracer_Z_init(tr, h, filename, tr_name, G, GV, US, missing_val, land_val, scale) logical :: tracer_Z_init !< A return code indicating if the initialization has been successful type(ocean_grid_type), intent(in) :: G !< The ocean's grid structure type(verticalGrid_type), intent(in) :: GV !< The ocean's vertical grid structure. type(unit_scale_type), intent(in) :: US !< A dimensional unit scaling type real, dimension(SZI_(G),SZJ_(G),SZK_(GV)), & - intent(out) :: tr !< The tracer to initialize + intent(out) :: tr !< The tracer to initialize [CU ~> conc] real, dimension(SZI_(G),SZJ_(G),SZK_(GV)), & - intent(in) :: h !< Layer thicknesses [H ~> m or kg m-2] - character(len=*), intent(in) :: filename !< The name of the file to read from - character(len=*), intent(in) :: tr_name !< The name of the tracer in the file - real, optional, intent(in) :: missing_val !< The missing value for the tracer - real, optional, intent(in) :: land_val !< A value to use to fill in land points - -!

The split of the loop due to the cuberoot caused ustar to be assigned in a separate loop, leaving it uninitialized for the length scale diagnostics loop. It also had its dimensions removed. However, the whole point of the new cuberoot() function was to preserve its dimensions, so there was no need for the intermediate dimensional manipulation, and all dimensionality should be shifted to the registration. This patch removes the intermediate dimensions and also explicitly defines it as Z2/H rather than L. * Bodner diagnostic: Restore scaling to L The scaling of the Bodner lengthscale diagnostic is correctly restored to L in this patch. The Z2 H-1 constant is factored into the calculation of the lengthscale; I believe this represents a conversion from a [Z2 T-2]-like momentum flux to a [LH T-2]-like momentum flux. A generic `uflux_rescale` term was introduced to be used in both ld_bodner and wpup, to avoid a double division by SpV. The if-block for computation of ld_bodner was also moved outside of the loop, in order to facilitate vectorization. --------- Co-authored-by: Liz Drenkard Co-authored-by: Kate Hedstrom --- .../lateral/MOM_mixed_layer_restrat.F90 | 58 ++++++++++++++++--- 1 file changed, 49 insertions(+), 9 deletions(-) diff --git a/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 b/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 index c10a55309b..0efe322a1d 100644 --- a/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 +++ b/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 @@ -120,6 +120,7 @@ module MOM_mixed_layer_restrat integer :: id_wpup = -1 integer :: id_ustar = -1 integer :: id_bflux = -1 + integer :: id_lfbod = -1 !>@} end type mixedlayer_restrat_CS @@ -807,6 +808,7 @@ subroutine mixedlayer_restrat_Bodner(CS, G, GV, US, h, uhtr, vhtr, tv, forces, d wpup !

We add parentheses and reorder terms in selected expressions which either direct or suppress FMAs, ensuring equivalence with the previous release. We address two specific equations in the PR. The first is associated with vertical friction coupling coupling coefficient. The diff is shown below. - a_cpl(i,K) = Kv_tot(i,K) / (h_shear*GV%H_to_Z + I_amax*Kv_tot(i,K)) + a_cpl(i,K) = Kv_tot(i,K) / (h_shear + I_amax*Kv_tot(i,K)) The denominator is of the form `a*b + c*d`. A compiler may favor an FMA of the form `a*b + (c*d)`. However, the modified equation is of form which favors the `a + c*d` FMA. Each form gives different results in the final bits. We resolve this by expliciting wrapping the RHS in parentheses: a_cpl(i,K) = Kv_tot(i,K) / (h_shear + (I_amax*Kv_tot(i,K))) Although this disables the FMA, it produces the same bit-equivalent answer as the original expression. ---- The second equation for TKE due to kappa shear is shown below. - tke_src = dz_Int(K) *(((kappa(K) + kappa0)*S2(K) - kappa(k)*N2(K)) - & - (TKE(k) - q0)*TKE_decay(k)) - & + tke_src = h_Int(K) * (dz_h_Int(K)*((kappa(K) + kappa0)*S2(K) - kappa(k)*N2(K)) - & + (TKE(k) - q0)*TKE_decay(k)) - & ... The outer equation was of the form `b + c` but is promoted to `a*b + c`, transforming it to an FMA. We resolve this by suppressing this FMA optimization: tke_src = h_Int(K) * ((dz_h_Int(K) * ((kappa(K) + kappa0)*S2(K) - kappa(k)*N2(K))) - & (TKE(k) - q0)*TKE_decay(k)) - & ... ---- The following two changes are intended to be the smallest modification which preserves answers for known testing on target compilers. It does not encompass all equation changes in this PR. If needed, we could extend these changes to similar modifications of PR#1616. We do not expect to support bit reproducibility when FMAs are enabled. But this is an ongoing conversation, and the rules around FMAs should be expected to change as we learn more and agree on rules of reproducibility. --- src/parameterizations/vertical/MOM_kappa_shear.F90 | 2 +- src/parameterizations/vertical/MOM_vert_friction.F90 | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/src/parameterizations/vertical/MOM_kappa_shear.F90 b/src/parameterizations/vertical/MOM_kappa_shear.F90 index 81ab0661cc..8a1974d8ea 100644 --- a/src/parameterizations/vertical/MOM_kappa_shear.F90 +++ b/src/parameterizations/vertical/MOM_kappa_shear.F90 @@ -1618,7 +1618,7 @@ subroutine find_kappa_tke(N2, S2, kappa_in, Idz, h_Int, dz_Int, dz_h_Int, I_L2_b !

Since the namespaces inside blocks are not shared or inherited, this was creating a new parameter, `MLE%DEFAULT_ANSWER_DATE`, whose value differed from the global `DEFAULT_ANSWER_DATE`. This was causing unintuitive behavior of `MLE%ML_RESTRAT_ANSWER_DATE`, which ignored this global answer date. This patch reads `DEFAULT_ANSWER_DATE` outside of the block, so that `ML_RESTRAT_ANSWER_DATE` now defaults to the global value. --- src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 b/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 index 0efe322a1d..057943a788 100644 --- a/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 +++ b/src/parameterizations/lateral/MOM_mixed_layer_restrat.F90 @@ -1616,6 +1616,9 @@ logical function mixedlayer_restrat_init(Time, G, GV, US, param_file, diag, CS, CS%use_Bodner = .false. call get_param(param_file, mdl, "DEBUG", CS%debug, default=.false., do_not_log=.true.) + call get_param(param_file, mdl, "DEFAULT_ANSWER_DATE", default_answer_date, & + "This sets the default value for the various _ANSWER_DATE parameters.", & + default=99991231, do_not_log=.true.) call openParameterBlock(param_file,'MLE') !

These were problematic because these arguments were previously in the wrong positions and hence were being used for the wrong variables inside of build_rho_column. In Boussinesq mode, the results will be the same as long as there is no dimensional rescaling being applied to thicknesses, and it this were being tested it would have resulted in a dimensional consistency test failure. In non-Boussinesq mode, the values of H_subroundoff as used for this coordinate will be off by a factor of RHO_KV_CONVERT (usually 1035), but these thicknesses are so small that they do not matter unless ANGSTROM is explicitly set to zero (when no dimensional rescaling is being used). To summarize, this fixes a bug that has been around since 2017, and while this fix could slightly change some diagnostics that are remapped to density, it only does so in circumstances that are unlikely to have been realized. No answer changes were detected in the MOM6-examples regression suite, and almost certainly none ever would be in any existing use of MOM6. --- src/framework/MOM_diag_remap.F90 | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/framework/MOM_diag_remap.F90 b/src/framework/MOM_diag_remap.F90 index a2ecc197bc..0e2e594403 100644 --- a/src/framework/MOM_diag_remap.F90 +++ b/src/framework/MOM_diag_remap.F90 @@ -326,7 +326,7 @@ subroutine diag_remap_update(remap_cs, G, GV, US, h, T, S, eqn_of_state, h_targe elseif (remap_cs%vertical_coord == coordinateMode('RHO')) then call build_rho_column(get_rho_CS(remap_cs%regrid_cs), GV%ke, & GV%Z_to_H*(G%bathyT(i,j)+G%Z_ref), h(i,j,:), T(i,j,:), S(i,j,:), & - eqn_of_state, zInterfaces, h_neglect, h_neglect_edge) + eqn_of_state, zInterfaces, h_neglect=h_neglect, h_neglect_edge=h_neglect_edge) elseif (remap_cs%vertical_coord == coordinateMode('HYCOM1')) then ! call build_hycom1_column(remap_cs%regrid_cs, nz, & !

This change means that the non-Boussinesq open boundary condition calculations avoid using the Boussinesq reference density. Associated with this change, 5 internal variables in update_OBC_segment_data were renamed to reflect that they are layer vertical extents instead of thicknesses. Also added or amended comments describing the purpose and units of 25 real variables in this module and corrected a handful of lines in this module that were not adhering to the guidance in the MOM6 style guide. Answers are bitwise identical in any Boussinesq cases.

This unit rescaling is duplicative of the conversion factors in the register_diag_field calls for these diagnostics (at about line 263). This will change these two diagnostics by a factor of RHO_0. This bug arose from separate and independent changes coming from GFDL and NCAR to add the same missing rescaling factor, and it might have gone undetected because of the vast range of valid values for CFC concentrations or because all of our regression testing uses calendar dates that precede the invention and first release of CFCs in the 1930s. Although this commit will correct the code that is on the dev/gfdl branch, care will have to be taken when merging in modified versions of this file from other branches that might have also corrected this bug to avoid reintroducing it (perhaps in reverse). Also replaced the expression for the CFC flux rescaling factor for use with KPP_NonLocalTransport with GV%RZ_to_H, which is equivalent to the previous expression in Boussinesq mode but avoids a multiplication and division by the Boussinesq reference density in non-Boussinesq mode. All Boussinesq answers are identical, but some non-Boussinesq CFCs could be altered in the last bits. This PR will change diagnostics of CFC concentrations by about 3 orders of magnitude. The internal representation of the CFCs is bitwise identical in all Boussinesq cases, but they may change at roundoff in non-Boussinesq cases that use KPP. --- src/tracer/MOM_CFC_cap.F90 | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/src/tracer/MOM_CFC_cap.F90 b/src/tracer/MOM_CFC_cap.F90 index 16506b41c3..489948a63c 100644 --- a/src/tracer/MOM_CFC_cap.F90 +++ b/src/tracer/MOM_CFC_cap.F90 @@ -361,7 +361,6 @@ subroutine CFC_cap_column_physics(h_old, h_new, ea, eb, fluxes, dt, G, GV, US, C !

If unset, deps/ is placed in the BUILD directory. * results/ is moved into WORK. * Compiler flags which track directories now use $(abspath ...) to allow for arbitrary paths. * GitHub CI paths were adjusted to support these new settings. * DO_* flags are now used as on/off with ifdef testing, rather than checking for `true` values. * mkmf macros have been removed from the coupled test config. * The default FMS infra has been changed to FMS2 in all components, including the configure.ac outside of .testing. This work will enable testing of multiple FMS libraries in our CI. --- .github/actions/testing-setup/action.yml | 2 +- .testing/Makefile | 456 ++++++++++++----------- ac/configure.ac | 4 +- 3 files changed, 244 insertions(+), 218 deletions(-) diff --git a/.github/actions/testing-setup/action.yml b/.github/actions/testing-setup/action.yml index a15dd6d0a2..60499d4be1 100644 --- a/.github/actions/testing-setup/action.yml +++ b/.github/actions/testing-setup/action.yml @@ -28,7 +28,7 @@ runs: run: | echo "::group::Compile FMS library" cd .testing -

A number of logical branch points have been moved outside of the innermost do loops. This refactoring will also make it easier to provide alternatives to some of the solvers that do not use the trigonometric functions to solve for the roots of a cubic expression and avoiding the issues noted at NOAA-GFDL/MOM6/issues/483. All answers are bitwise identical and public interfaces are unchanged. --- .../vertical/MOM_set_viscosity.F90 | 511 +++++++++++------- 1 file changed, 322 insertions(+), 189 deletions(-) diff --git a/src/parameterizations/vertical/MOM_set_viscosity.F90 b/src/parameterizations/vertical/MOM_set_viscosity.F90 index b207b1ff1c..bf0db51a44 100644 --- a/src/parameterizations/vertical/MOM_set_viscosity.F90 +++ b/src/parameterizations/vertical/MOM_set_viscosity.F90 @@ -20,6 +20,7 @@ module MOM_set_visc use MOM_grid, only : ocean_grid_type use MOM_hor_index, only : hor_index_type use MOM_interface_heights, only : thickness_to_dz +! use MOM_intrinsic_functions, only : cuberoot use MOM_io, only : slasher, MOM_read_data, vardesc, var_desc use MOM_kappa_shear, only : kappa_shear_is_used, kappa_shear_at_vertex use MOM_open_boundary, only : ocean_OBC_type, OBC_segment_type, OBC_NONE, OBC_DIRECTION_E @@ -258,40 +259,15 @@ subroutine set_viscous_BBL(u, v, h, tv, visc, G, GV, US, CS, pbv) real :: crv ! crv is the curvature of the bottom depth across a ! cell, times the cell width squared [Z ~> m]. real :: crv_3 ! crv/3 [Z ~> m]. - real :: C24_crv ! 24/crv [Z-1 ~> m-1]. real :: slope !

These solutions are analogous to those given by the previous expressions that are now in find_L_open_concave_trigonometric, and the two differ at close to roundoff, but the new method is completely independent of the transcendental function library, thereby addressing dev/gfdl MOM6 issue #483. This new routine is called when the new runtime parameter TRIG_CHANNEL_DRAG_WIDTHS is set to false, but by default the previous answers are recovered. By default all answers are bitwise identical, but there is a new runtime parameter in some MOM_parameter_doc files. --- .../vertical/MOM_set_viscosity.F90 | 389 +++++++++++++++++- 1 file changed, 370 insertions(+), 19 deletions(-) diff --git a/src/parameterizations/vertical/MOM_set_viscosity.F90 b/src/parameterizations/vertical/MOM_set_viscosity.F90 index bf0db51a44..b25d660957 100644 --- a/src/parameterizations/vertical/MOM_set_viscosity.F90 +++ b/src/parameterizations/vertical/MOM_set_viscosity.F90 @@ -20,7 +20,7 @@ module MOM_set_visc use MOM_grid, only : ocean_grid_type use MOM_hor_index, only : hor_index_type use MOM_interface_heights, only : thickness_to_dz -! use MOM_intrinsic_functions, only : cuberoot +use MOM_intrinsic_functions, only : cuberoot use MOM_io, only : slasher, MOM_read_data, vardesc, var_desc use MOM_kappa_shear, only : kappa_shear_is_used, kappa_shear_at_vertex use MOM_open_boundary, only : ocean_OBC_type, OBC_segment_type, OBC_NONE, OBC_DIRECTION_E @@ -101,6 +101,8 @@ module MOM_set_visc real :: omega_frac !< When setting the decay scale for turbulence, use this !! fraction of the absolute rotation rate blended with the local !! value of f, as sqrt((1-of)*f^2 + of*4*omega^2) [nondim] + logical :: concave_trigonometric_L !< If true, use trigonometric expressions to determine the + !! fractional open interface lengths for concave topography. integer :: answer_date !< The vintage of the order of arithmetic and expressions in the set !! viscosity calculations.

Rather than passing in absolute array extents to work on, an ocean grid type is now passed as an argument to myStats, with the new optional full_halo argument used to capture the case where the tracer statistics are being taken over the full data domain. The most frequently encountered problems occurred when the hard-coded debug variable in the horiz_interp_and_extrap_tracer routines are changed from false to true. When global indexing is not used, this revised work exactly as before, but when it is used with global indexing, it avoids segmentation faults that were preventing the model from running in some cases with all debugging enabled. --- src/framework/MOM_horizontal_regridding.F90 | 44 +++++++++++-------- .../MOM_tracer_initialization_from_Z.F90 | 2 +- 2 files changed, 26 insertions(+), 20 deletions(-) diff --git a/src/framework/MOM_horizontal_regridding.F90 b/src/framework/MOM_horizontal_regridding.F90 index 34d0b73cb9..205dd6d7be 100644 --- a/src/framework/MOM_horizontal_regridding.F90 +++ b/src/framework/MOM_horizontal_regridding.F90 @@ -44,27 +44,32 @@ module MOM_horizontal_regridding contains !> Write to the terminal some basic statistics about the k-th level of an array -subroutine myStats(array, missing, is, ie, js, je, k, mesg, scale) - real, dimension(:,:), intent(in) :: array !< input array in arbitrary units [A ~> a] - real, intent(in) :: missing !< missing value in arbitrary units [A ~> a] - integer, intent(in) :: is !< Start index in i - integer, intent(in) :: ie !< End index in i - integer, intent(in) :: js !< Start index in j - integer, intent(in) :: je !< End index in j - integer, intent(in) :: k !< Level to calculate statistics for - character(len=*), intent(in) :: mesg !< Label to use in message - real, optional, intent(in) :: scale !< A scaling factor for output [a A-1 ~> 1] +subroutine myStats(array, missing, G, k, mesg, scale, full_halo) + type(ocean_grid_type), intent(in) :: G !< Ocean grid type + real, dimension(SZI_(G),SZJ_(G)), & + intent(in) :: array !< input array in arbitrary units [A ~> a] + real, intent(in) :: missing !< missing value in arbitrary units [A ~> a] + integer, intent(in) :: k !< Level to calculate statistics for + character(len=*), intent(in) :: mesg !< Label to use in message + real, optional, intent(in) :: scale !< A scaling factor for output [a A-1 ~> 1] + logical, optional, intent(in) :: full_halo !< If present and true, test values on the whole + !! array rather than just the computational domain. !

This was done by adding internal routines that set the loop indices consistently with the NE c-grid convention used throughout the MOM6 code and converting the optionally associated mask pointer into an optional argument. It also simplifies the logic of many of the expressions within the remapping code. There is also a new element, Z_based_coord, in the diag_remap_ctrl type, to indicate whether the remapping is working in thickness or height units, but for now it is always set to false. The function set_h_neglect or set_dz_neglect is used to set the negligible thicknesses used for remapping in diag_remap_update and diag_remap_do_remap, depending on whether the remapping is being done in thickness or vertical height coordinates. Diag_remap_init has a new vertical_grid_type argument, and diag_remap_do_remap has a new unit_scale_type argument. For REMAPPING_ANSWER_DATES later than 20240201, diag_remap_updated does an explicit sum to determine the total water column thickness, rather than using sum function, which is indeterminate of the order of the sums. For some compilers, this could change the vertical grids used for remapping diagnostics at roundoff, but no such change was detected for any of the compilers used with the MOM6 regression test suite. All answers and diagnostics in cases that worked before are bitwise identical, but there are new arguments to two publicly visible interfaces. --- src/framework/MOM_diag_mediator.F90 | 4 +- src/framework/MOM_diag_remap.F90 | 720 +++++++++++++++++----------- 2 files changed, 439 insertions(+), 285 deletions(-) diff --git a/src/framework/MOM_diag_mediator.F90 b/src/framework/MOM_diag_mediator.F90 index 2c71a93e42..61bfa93046 100644 --- a/src/framework/MOM_diag_mediator.F90 +++ b/src/framework/MOM_diag_mediator.F90 @@ -1583,7 +1583,7 @@ subroutine post_data_3d(diag_field_id, field, diag_cs, is_static, mask, alt_h) if (id_clock_diag_remap>0) call cpu_clock_begin(id_clock_diag_remap) allocate(remapped_field(size(field,1), size(field,2), diag%axes%nz)) call diag_remap_do_remap(diag_cs%diag_remap_cs(diag%axes%vertical_coordinate_number), & - diag_cs%G, diag_cs%GV, h_diag, staggered_in_x, staggered_in_y, & + diag_cs%G, diag_cs%GV, diag_cs%US, h_diag, staggered_in_x, staggered_in_y, & diag%axes%mask3d, field, remapped_field) if (id_clock_diag_remap>0) call cpu_clock_end(id_clock_diag_remap) if (associated(diag%axes%mask3d)) then @@ -3207,7 +3207,7 @@ subroutine diag_mediator_init(G, GV, US, nz, param_file, diag_cs, doc_file_dir) allocate(diag_cs%diag_remap_cs(diag_cs%num_diag_coords)) !

The subroutine thickness_to_dz is used with the thermo_vars_type to do the rescaling properly in non-Boussinesq mode. A new thermo_var_ptrs argument was added to diag_mediator_init, replacing three other arguments that had the same information, and its call from MOM.F90 was modified accordingly. The various calls to the diag_remap routines from post_data_3d and diag_update_remap_grids were modified depending on whether a z-unit or h-unit vertical grid is being remapped to. All answers and diagnostics are identical in Boussinesq mode, but some remapped diagnostics are changed (by not using expressions that depend on the Boussinesq reference density) in the non-Boussinesq mode. There are altered or augmented public arguments to two publicly visible routines. --- src/core/MOM.F90 | 5 +- src/framework/MOM_diag_mediator.F90 | 158 +++++++++++++++++++++------- src/framework/MOM_diag_remap.F90 | 13 +-- 3 files changed, 131 insertions(+), 45 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 2bf2b11b1a..094e534312 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -3152,14 +3152,15 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, & !

This involves passing the starting index in memory of the native-grid field being downsampled in all calls to downsample_mask. In global-indexing mode, this change avoids a series of segmentation faults that stopped the model runs when compiled for debugging. All solutions are bitwise identical in all cases but some down-scaled diagnostics will change in some memory modes, hopefully becoming consistent across all memory modes (although this has yet to be tested in all modes). --- src/framework/MOM_diag_mediator.F90 | 80 +++++++++++++++++------------ 1 file changed, 46 insertions(+), 34 deletions(-) diff --git a/src/framework/MOM_diag_mediator.F90 b/src/framework/MOM_diag_mediator.F90 index 6c90e26b98..eeb239859d 100644 --- a/src/framework/MOM_diag_mediator.F90 +++ b/src/framework/MOM_diag_mediator.F90 @@ -872,43 +872,51 @@ subroutine set_masks_for_axes_dsamp(G, diag_cs) do c=1, diag_cs%num_diag_coords !

The following checksums are declared as scalar pairs, rather than vectors: * eta_[uv] (in porous barrier) * por_face_area[UV] * por_layer_width[UV] * Ray_[uv] (Rayleigh drag velocity) Fluxes and surface fields are now permitted to contain tracer fluxes (tr_fluxes) when rotation is enabled. The fields are retained in their unrotated form, since these are accessed and handled outside of MOM6. The rotated p_surf_SSH pointer in forces now correctly points to either p_surf or p_surf_full. read_netcdf_nc() now correctly uses the unrotated horizontal index struct HI, used to access the contents of the file. Previously, it was using the model HI, which may be rotated. Reading chlorophyll with time_interp_external now uses rotation to correctly fetch its output. NOTE: This could be cleaned up so that the rotation details are hidden from users, but there are some unresolved issues around how to approach this. --- src/core/MOM_forcing_type.F90 | 19 +++++++++++++++---- src/core/MOM_porous_barriers.F90 | 10 ++++++---- src/core/MOM_variables.F90 | 9 ++++++--- src/framework/MOM_io_file.F90 | 8 +++++++- .../vertical/MOM_diabatic_aux.F90 | 8 ++++++-- .../vertical/MOM_set_diffusivity.F90 | 3 ++- .../vertical/MOM_set_viscosity.F90 | 3 ++- 7 files changed, 44 insertions(+), 16 deletions(-) diff --git a/src/core/MOM_forcing_type.F90 b/src/core/MOM_forcing_type.F90 index 98cfdb3f17..452161c6ca 100644 --- a/src/core/MOM_forcing_type.F90 +++ b/src/core/MOM_forcing_type.F90 @@ -6,6 +6,7 @@ module MOM_forcing_type use MOM_array_transform, only : rotate_array, rotate_vector, rotate_array_pair use MOM_coupler_types, only : coupler_2d_bc_type, coupler_type_destructor use MOM_coupler_types, only : coupler_type_increment_data, coupler_type_initialized +use MOM_coupler_types, only : coupler_type_copy_data use MOM_cpu_clock, only : cpu_clock_id, cpu_clock_begin, cpu_clock_end, CLOCK_ROUTINE use MOM_debugging, only : hchksum, uvchksum use MOM_diag_mediator, only : post_data, register_diag_field, register_scalar_field @@ -3702,9 +3703,11 @@ subroutine rotate_forcing(fluxes_in, fluxes, turns) if (associated(fluxes_in%ustar_tidal)) & call rotate_array(fluxes_in%ustar_tidal, turns, fluxes%ustar_tidal) - !

Most are false positives from stub functions which would normally be replaced in production and report unset output. These variables are now assigned dummy values in order to pacify the compiler. The `stat` function in POSIX was incorrectly passing its `buf` object to the C `stat` function as `intent(in)`, causing the compiler to believe that the contents were unset. Oddly, this was already working correctly, and perhaps warrants further investigation, but it has now been correctly set to `intent(inout)`. The `ppoly_*` variables in `check_reconstruction_1d` appear to have been incorrectly declared as `out`, when they are clearly used as `in` to validate the values. This has been corrected. `register_diag_field` in the ice shelf diag manager was incorrectly declared and the function appeared to return nothing. Perhaps this function was not used for anything. An IO statement in MOM_open_boundary had a syntax error; this has been fixed. `get_dataset` returns a `dataset_type`, so some compilers expect the stub function to also return a valid `dataset`. Since the stub `dataset_type` contains no fields, any locally declared instance should be sufficient as a return value. --- .../GFDL_ocean_BGC/FMS_coupler_util.F90 | 2 ++ .../GFDL_ocean_BGC/generic_tracer_utils.F90 | 29 +++++++++++++++++++ .../database_client_interface.F90 | 19 ++++++++++++ src/ALE/MOM_remapping.F90 | 6 ++-- src/core/MOM_open_boundary.F90 | 2 +- src/framework/MOM_io_file.F90 | 2 ++ src/framework/posix.F90 | 2 +- src/ice_shelf/MOM_ice_shelf_diag_mediator.F90 | 6 ++-- 8 files changed, 60 insertions(+), 8 deletions(-) diff --git a/config_src/external/GFDL_ocean_BGC/FMS_coupler_util.F90 b/config_src/external/GFDL_ocean_BGC/FMS_coupler_util.F90 index b7ee7de684..5d78e0d501 100644 --- a/config_src/external/GFDL_ocean_BGC/FMS_coupler_util.F90 +++ b/config_src/external/GFDL_ocean_BGC/FMS_coupler_util.F90 @@ -22,6 +22,8 @@ subroutine extract_coupler_values(BC_struc, BC_index, BC_element, array_out, ilb integer, optional, intent(in) :: js !< The j- limits of array_out to be filled integer, optional, intent(in) :: je !< The j- limits of array_out to be filled real, optional, intent(in) :: conversion !< A number that every element is multiplied by + + array_out(:,:) = -1. end subroutine extract_coupler_values !> Set element and index of a boundary condition diff --git a/config_src/external/GFDL_ocean_BGC/generic_tracer_utils.F90 b/config_src/external/GFDL_ocean_BGC/generic_tracer_utils.F90 index ea9f225a27..fec9c80461 100644 --- a/config_src/external/GFDL_ocean_BGC/generic_tracer_utils.F90 +++ b/config_src/external/GFDL_ocean_BGC/generic_tracer_utils.F90 @@ -143,6 +143,17 @@ subroutine g_tracer_get_common(isc,iec,jsc,jec,isd,ied,jsd,jed,nk,ntau,& integer, optional, dimension(:,:), pointer :: grid_mask_coast !< Unknown integer, optional, dimension(:,:), pointer :: grid_kmt !< Unknown type(g_diag_ctrl), optional, pointer :: diag_CS !< Unknown + + isc = -1 + iec = -1 + jsc = -1 + jec = -1 + isd = -1 + ied = -1 + jsd = -1 + jed = -1 + nk = -1 + ntau = -1 end subroutine g_tracer_get_common !> Unknown @@ -177,6 +188,8 @@ subroutine g_tracer_get_4D_val(g_tracer_list,name,member,array,isd,jsd) integer, intent(in) :: isd !< Unknown integer, intent(in) :: jsd !< Unknown real, dimension(isd:,jsd:,:,:), intent(out):: array !< Unknown + + array(:,:,:,:) = -1. end subroutine g_tracer_get_4D_val !> Unknown @@ -190,6 +203,8 @@ subroutine g_tracer_get_3D_val(g_tracer_list,name,member,array,isd,jsd,ntau,posi logical, optional, intent(in) :: positive !< Unknown real, dimension(isd:,jsd:,:), intent(out):: array !< Unknown character(len=fm_string_len), parameter :: sub_name = 'g_tracer_get_3D_val' + + array(:,:,:) = -1. end subroutine g_tracer_get_3D_val !> Unknown @@ -200,6 +215,8 @@ subroutine g_tracer_get_2D_val(g_tracer_list,name,member,array,isd,jsd) integer, intent(in) :: isd !< Unknown integer, intent(in) :: jsd !< Unknown real, dimension(isd:,jsd:), intent(out):: array !< Unknown + + array(:,:) = -1. end subroutine g_tracer_get_2D_val !> Unknown @@ -208,6 +225,8 @@ subroutine g_tracer_get_real(g_tracer_list,name,member,value) character(len=*), intent(in) :: member !< Unknown type(g_tracer_type), pointer :: g_tracer_list !< Unknown real, intent(out):: value !< Unknown + + value = -1 end subroutine g_tracer_get_real !> Unknown @@ -216,6 +235,8 @@ subroutine g_tracer_get_string(g_tracer_list,name,member,string) character(len=*), intent(in) :: member !< Unknown type(g_tracer_type), pointer :: g_tracer_list !< Unknown character(len=fm_string_len), intent(out) :: string !< Unknown + + string = "" end subroutine g_tracer_get_string !> Unknown @@ -268,18 +289,24 @@ end subroutine g_tracer_send_diag subroutine g_tracer_get_name(g_tracer,string) type(g_tracer_type), pointer :: g_tracer !< Unknown character(len=*), intent(out) :: string !< Unknown + + string = "" end subroutine g_tracer_get_name !> Unknown subroutine g_tracer_get_alias(g_tracer,string) type(g_tracer_type), pointer :: g_tracer !< Unknown character(len=*), intent(out) :: string !< Unknown + + string = "" end subroutine g_tracer_get_alias !> Is the tracer prognostic?

Because MOM6 and SIS2 use some common framework code but are managed in separate github repositories, we need to use optional argument to allow a single version of SIS2 to work across changes to MOM6 interfaces. Because the TOPO_CONFIG parameter as used in SIS2 has a default value, there is an alternative call to get_param for TOPO_CONFIG with a default when MOM_domains_init is called with a domain_name argument. Also added missing scale arguments to get_param calls for MINIMUM_DEPTH and MASKING_DEPTH. This commit also adds or corrects units in the comments describing 4 recently added or modified variables. All answers are bitwise identical in any cases that worked before (noting that some cases using SIS2 would not even compile). --- src/core/MOM.F90 | 12 ++--- src/framework/MOM_domains.F90 | 54 ++++++++++++------- src/ice_shelf/MOM_ice_shelf.F90 | 4 +- src/ocean_data_assim/MOM_oda_driver.F90 | 2 +- .../lateral/MOM_hor_visc.F90 | 2 +- 5 files changed, 45 insertions(+), 29 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index b7f8bd3f66..a9c8c5cd9e 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -2538,13 +2538,13 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, & #endif G_in => CS%G_in #ifdef STATIC_MEMORY_ - call MOM_domains_init(G_in%domain, US, param_file, symmetric=symmetric, & - static_memory=.true., NIHALO=NIHALO_, NJHALO=NJHALO_, & - NIGLOBAL=NIGLOBAL_, NJGLOBAL=NJGLOBAL_, NIPROC=NIPROC_, & - NJPROC=NJPROC_) + call MOM_domains_init(G_in%domain, param_file, symmetric=symmetric, & + static_memory=.true., NIHALO=NIHALO_, NJHALO=NJHALO_, & + NIGLOBAL=NIGLOBAL_, NJGLOBAL=NJGLOBAL_, NIPROC=NIPROC_, & + NJPROC=NJPROC_, US=US) #else - call MOM_domains_init(G_in%domain, US, param_file, symmetric=symmetric, & - domain_name="MOM_in") + call MOM_domains_init(G_in%domain, param_file, symmetric=symmetric, & + domain_name="MOM_in", US=US) #endif !

All answers are bitwise identical in cases that worked correctly before. --- config_src/infra/FMS1/MOM_domain_infra.F90 | 26 ++++++++++++++++++++-- config_src/infra/FMS2/MOM_domain_infra.F90 | 26 ++++++++++++++++++++-- 2 files changed, 48 insertions(+), 4 deletions(-) diff --git a/config_src/infra/FMS1/MOM_domain_infra.F90 b/config_src/infra/FMS1/MOM_domain_infra.F90 index 2c97a0bb31..8040be27d9 100644 --- a/config_src/infra/FMS1/MOM_domain_infra.F90 +++ b/config_src/infra/FMS1/MOM_domain_infra.F90 @@ -19,7 +19,8 @@ module MOM_domain_infra use mpp_domains_mod, only : mpp_compute_block_extent use mpp_domains_mod, only : mpp_broadcast_domain, mpp_redistribute, mpp_global_field use mpp_domains_mod, only : AGRID, BGRID_NE, CGRID_NE, SCALAR_PAIR, BITWISE_EXACT_SUM -use mpp_domains_mod, only : CYCLIC_GLOBAL_DOMAIN, FOLD_NORTH_EDGE +use mpp_domains_mod, only : CYCLIC_GLOBAL_DOMAIN +use mpp_domains_mod, only : FOLD_NORTH_EDGE, FOLD_SOUTH_EDGE, FOLD_EAST_EDGE, FOLD_WEST_EDGE use mpp_domains_mod, only : To_East => WUPDATE, To_West => EUPDATE, Omit_Corners => EDGEUPDATE use mpp_domains_mod, only : To_North => SUPDATE, To_South => NUPDATE use mpp_domains_mod, only : CENTER, CORNER, NORTH_FACE => NORTH, EAST_FACE => EAST @@ -1553,6 +1554,19 @@ subroutine clone_MD_to_MD(MD_in, MOM_dom, min_halo, halo_size, symmetric, domain call get_layout_extents(MD_in, exnj, exni) MOM_dom%X_FLAGS = MD_in%Y_FLAGS ; MOM_dom%Y_FLAGS = MD_in%X_FLAGS + !

This option is enabled by setting the new runtime parameter HOR_DIFF_ANSWER_DATE to be greater than 20240330. By default, this parameter is set to use the previous expressions, although the default may be changed later to follow DEFAULT_ANSWER_DATE. Also corrected two bugs with the tracer limits used to repartition the fluxes between layers within tracer_epipycnal_ML_diff; this correction is enables by setting the new HOR_DIFF_LIMIT_BUG to .false., but to retain previous answers by default it is set to true.

Similarly the thicknesses and transports output by write_u_accel and write_v_accel are in mass per unit area or mass flux per unit face length in non-Boussinesq mode. This is done specifically by using GV%H_to_MKS in place of GV%H_to_m; these are identical in Boussinesq mode, but GV%H_to_MKS avoids rescaling by the Boussinesq reference density in non-Boussinesq mode. Several comments were also updated to reflect these changes. All solutions are identical, but there are changes in the units of several diagnostic output fields that the model can write out when debugging non-Boussinesq mode runs. --- src/core/MOM_checksum_packages.F90 | 13 +++++++------ src/diagnostics/MOM_PointAccel.F90 | 18 ++++++++++-------- src/tracer/MOM_tracer_registry.F90 | 20 ++++++++++++-------- 3 files changed, 29 insertions(+), 22 deletions(-) diff --git a/src/core/MOM_checksum_packages.F90 b/src/core/MOM_checksum_packages.F90 index 4a9df04c4d..dc60e0888f 100644 --- a/src/core/MOM_checksum_packages.F90 +++ b/src/core/MOM_checksum_packages.F90 @@ -268,10 +268,11 @@ subroutine MOM_state_stats(mesg, u, v, h, Temp, Salt, G, GV, US, allowChange, pe !

The following are supported: * Nearly all operators, including arithmetic, logical, and bitwise, * Parentheses within expressions, * defined() evaluations. The following are explicitly not supported: * Function macros, * Multiline preprocessors. No doubt there are other lingering issues, but this is comprehensive enough to handle both MOM6 as well as current and legacy FMS source codes. Existing Makefile.dep output files appear to be mostly unchanged. One rule (data_override.o) had its arguments reordered but is otherwise unchanged. mpp_data.o had its rule corrected to use mpp_util_mpi.inc rather than mpp_util_nocomm.inc. Some fixes and adjustments were made to the overall makedep source: * Input macros (-D) are now stored as key-value dicts, rather than simply a list of macro names. * Input macros are now passed to all scan_fortran_file() calls, rather than just the Fortran source. * Input macros are now correctly passed to FMS makedep. Previously, these were omitted from the Makefile generation. * Previously, #if blocks were always set to True, even though the comments indicated that they were always set to False. Given that neither of these was ever correct, it's amazing that we were able to survive this long without prior incident. The motivation for this PR comes from issues with Makefile generation in FMS. Older versions of FMS were unable to correctly resolve their dependencies in fft.f90 on certain systems (perhaps caused by filesystem peculiarities). Newer versions of FMS were unable to handle the #if block default from True to False. Inevitably, we threw up our hands and solved the underlying problem. --- ac/deps/Makefile.fms.in | 2 +- ac/makedep | 205 +++++++++++++++++++++++++++++++++++++--- 2 files changed, 195 insertions(+), 12 deletions(-) diff --git a/ac/deps/Makefile.fms.in b/ac/deps/Makefile.fms.in index 71c46f082a..e4617f1428 100644 --- a/ac/deps/Makefile.fms.in +++ b/ac/deps/Makefile.fms.in @@ -23,4 +23,4 @@ ARFLAGS = @ARFLAGS@ .PHONY: depend depend: Makefile.dep Makefile.dep: - $(PYTHON) $(MAKEDEP) -o Makefile.dep -e -x libFMS.a -s @srcdir@/test_fms @srcdir@ + $(PYTHON) $(MAKEDEP) $(DEFS) -o Makefile.dep -e -x libFMS.a -s @srcdir@/test_fms @srcdir@ diff --git a/ac/makedep b/ac/makedep index e37f35aca5..4c9cc9229b 100755 --- a/ac/makedep +++ b/ac/makedep @@ -10,7 +10,8 @@ import re import sys -# Pre-compile re searches +# Fortran tokenization + re_module = re.compile(r"^ *module +([a-z_0-9]+)") re_use = re.compile(r"^ *use +([a-z_0-9]+)") re_cpp_define = re.compile(r"^ *# *define +[_a-zA-Z][_a-zA-Z0-9]") @@ -32,6 +33,80 @@ re_procedure = re.compile( ) +# Preprocessor expression tokenization +cpp_scanner = re.Scanner([ + (r'defined', lambda scanner, token: token), + (r'[_A-Za-z][_0-9a-zA-Z]*', lambda scanner, token: token), + (r'[0-9]+', lambda scanner, token: token), + (r'\(', lambda scanner, token: token), + (r'\)', lambda scanner, token: token), + (r'\*', lambda scanner, token: token), + (r'/', lambda scanner, token: token), + (r'\+', lambda scanner, token: token), + (r'-', lambda scanner, token: token), + (r'!', lambda scanner, token: token), + (r'>>', lambda scanner, token: token), + (r'>=', lambda scanner, token: token), + (r'>', lambda scanner, token: token), + (r'<<', lambda scanner, token: token), + (r'<=', lambda scanner, token: token), + (r'<', lambda scanner, token: token), + (r'==', lambda scanner, token: token), + (r'&&', lambda scanner, token: token), + (r'&', lambda scanner, token: token), + (r'\|\|', lambda scanner, token: token), + (r'\|', lambda scanner, token: token), + (r'^\#if', None), + (r'\s+', None), +]) + + +cpp_operate = { + '!': lambda x: not x, + '*': lambda x, y: x * y, + '/': lambda x, y: x // y, + '+': lambda x, y: x + y, + '-': lambda x, y: x - y, + '>>': lambda x, y: x >> y, + '<<': lambda x, y: x << y, + '==': lambda x, y: x == y, + '>': lambda x, y: x > y, + '>=': lambda x, y: x >= y, + '<': lambda x, y: x < y, + '<=': lambda x, y: x <= y, + '&': lambda x, y: x & y, + '^': lambda x, y: x ^ y, + '|': lambda x, y: x | y, + '&&': lambda x, y: x and y, + '||': lambda x, y: x or y, +} + + +cpp_op_rank = { + '(': 13, + '!': 12, + '*': 11, + '/': 11, + '+': 10, + '-': 10, + '>>': 9, + '<<': 9, + '>': 8, + '>=': 8, + '<': 8, + '<=': 8, + '==': 7, + '&': 6, + '^': 5, + '|': 4, + '&&': 2, + '||': 2, + ')': 1, + '$': 1, + None: 0, +} + + def create_deps(src_dirs, skip_dirs, makefile, debug, exec_target, fc_rule, link_externals, defines): """Create "makefile" after scanning "src_dis".""" @@ -105,7 +180,7 @@ def create_deps(src_dirs, skip_dirs, makefile, debug, exec_target, fc_rule, all_modules += mods for f in c_files: - _, _, cpp, inc, _, _ = scan_fortran_file(f) + _, _, cpp, inc, _, _ = scan_fortran_file(f, defines) # maps object file to .h files included o2h[object_file(f)] = cpp externals.append(object_file(f)) @@ -158,7 +233,7 @@ def create_deps(src_dirs, skip_dirs, makefile, debug, exec_target, fc_rule, ] missing_mods = [m for m in o2uses[o] if m not in all_modules] - incs, inc_used = nested_inc(o2h[o] + o2inc[o], f2F) + incs, inc_used = nested_inc(o2h[o] + o2inc[o], f2F, defines) inc_mods = [u for u in inc_used if u not in found_mods and u in all_modules] incdeps = sorted(set([f2F[f] for f in incs if f in f2F])) @@ -250,7 +325,7 @@ def link_obj(obj, o2uses, mod2o, all_modules): return sorted(set(olst)) -def nested_inc(inc_files, f2F): +def nested_inc(inc_files, f2F, defines): """List of all files included by "inc_files", either by #include or F90 include.""" hlst = [] @@ -260,7 +335,7 @@ def nested_inc(inc_files, f2F): if hfile not in f2F.keys(): return - _, used, cpp, inc, _, _ = scan_fortran_file(f2F[hfile]) + _, used, cpp, inc, _, _ = scan_fortran_file(f2F[hfile], defines) # Record any module updates inside of include files used_mods.update(used) @@ -286,7 +361,8 @@ def scan_fortran_file(src_file, defines=None): cpp_defines = defines if defines is not None else [] - cpp_macros = [define.split('=')[0] for define in cpp_defines] + #cpp_macros = [define.split('=')[0] for define in cpp_defines] + cpp_macros = dict([t.split('=') for t in cpp_defines]) cpp_group_stack = [] with io.open(src_file, 'r', errors='replace') as file: @@ -328,9 +404,9 @@ def scan_fortran_file(src_file, defines=None): if match: cpp_group_stack.append(cpp_exclude) - # XXX: Don't attempt to parse #if statements, but store the state. - # if/endif stack.

This bug appears to have been introduced when merging in code that updates the Stokes drifts that was added on one branch (dev/ncar) separately from changes in how these Stokes drifts are scaled in the mech_forcing type on anther branch (dev/gfdl), although it might just have been an oversight during refactoring. All answers are bitwise identical when no dimensional rescaling is being used, but answers could change for some uncommon cases using the Stokes drift spectrum when dimensional rescaling is applied. --- src/user/MOM_wave_interface.F90 | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/user/MOM_wave_interface.F90 b/src/user/MOM_wave_interface.F90 index 9a951cf655..656ff5b569 100644 --- a/src/user/MOM_wave_interface.F90 +++ b/src/user/MOM_wave_interface.F90 @@ -717,8 +717,8 @@ subroutine Update_Surface_Waves(G, GV, US, Time_present, dt, CS, forces) do i=G%isc,G%iec !CS%Omega_w2x(i,j) = forces%omega_w2x(i,j) do b=1,CS%NumBands - CS%UStk_Hb(i,j,b) = US%m_s_to_L_T*forces%UStkb(i,j,b) - CS%VStk_Hb(i,j,b) = US%m_s_to_L_T*forces%VStkb(i,j,b) + CS%UStk_Hb(i,j,b) = forces%UStkb(i,j,b) + CS%VStk_Hb(i,j,b) = forces%VStkb(i,j,b) enddo enddo enddo From 6c44c5f3843928c9b7b22aa8178148b0bb36e8ca Mon Sep 17 00:00:00 2001 From: Alistair Adcroft Date: Thu, 4 Apr 2024 16:12:37 -0400 Subject: [PATCH 1008/1329] Fix for using tidal amplitude in determining the BBL thickness Setting `BBL_USE_TIDAL_BG` in OM5_b003 revealed non-conservation and non-reproducibility across layouts. A scalar variable was correctly being set based on the tidal amplitude but was being used after a break between loops. - Replaced the scalar variable U_bg_sq with a vector u2_bg(:) that is set to either a constant or the square of the tidal amplitude. - The module parameter CS%drag_bg_vel was not set if using the tidal amplitude but WAS being used for conditionals. We now set it to 1e30 because it should NOT be used or impact the solution. Setting it to zero, or anything meaningful would allow code to use it inadvertently. This "constant" does not need to satisfy any dimensional testing. --- .../vertical/MOM_set_viscosity.F90 | 75 ++++++++++++------- 1 file changed, 47 insertions(+), 28 deletions(-) diff --git a/src/parameterizations/vertical/MOM_set_viscosity.F90 b/src/parameterizations/vertical/MOM_set_viscosity.F90 index e601fdf2f7..e16a57d970 100644 --- a/src/parameterizations/vertical/MOM_set_viscosity.F90 +++ b/src/parameterizations/vertical/MOM_set_viscosity.F90 @@ -59,6 +59,7 @@ module MOM_set_visc real :: drag_bg_vel !< An assumed unresolved background velocity for !! calculating the bottom drag [L T-1 ~> m s-1]. !!

Background: When an ice shelf is initialised in ALE mode, MOM_state_initialization first initialises the ocean thickness and T/S with topography, but without an ice shelf. It then calls the function trim_for_ice, which takes in input of the ice shelf pressure, and in turn calls cut_off_column_top which truncates the columns (and adds vanishing layers) to account for the pressure of the ice depressing the free surface. The output of this is a grid with the ice shelf boundary treated in a ALE z-coordinate fashion with vanishing layers at the surface, and @adcroft's upcoming changes will make T and S consistent to the grid. However, after adding the ice shelf, we still need to regrid and remap onto our desired ALE coordinate, for example sigma coordinates. This can be done with regrid_accelerate in MOM_state_initialization or by the block controlled by REMAP_AFTER_INITIALIZATION in MOM.F90 We want the initialisation to use boundary extrapolation in the remapping so that the boundary cells preserve the desired initialisation profile when remapped to their target coordinate. This is controlled by REMAP_BOUNDARY_EXTRAP, except this runtime parameter modifies the control structure for the dynamic part of the model run too, which is bad because it means extrema are not preserved in the ALE remapping and can lead to non-sensible values of tracers. Changes: * Added runtime parameter INIT_BOUNDARY_EXTRAP and set the ALE control structure to use that instead of REMAP_BOUNDARY_EXTRAP at first. The default of INIT_BOUNDARY_EXTRAP is REMAP_BOUNDARY_EXTRAP to preserve answers (though it is not recommended to use REMAP_BOUNDARY_EXTRAP during model dynamics...) * After ALE regrid/remap in MOM.F90 (final initialisation step using ALE), reset the boundary extrapolation flag in the ALE control structure to go back to REMAP_BOUNDARY_EXTRAP. This PR combined with @adcroft's upcoming changes should make the initialisation of the ocean thickness and TS in an ALE ice shelf cavity perfect, when the new flag INIT_BOUNDARY_EXTRAP = True and old flag REMAP_BOUNDARY_EXTRAP = False. --- src/ALE/MOM_ALE.F90 | 24 +++++++++++++++++++++--- src/core/MOM.F90 | 8 ++++++-- 2 files changed, 27 insertions(+), 5 deletions(-) diff --git a/src/ALE/MOM_ALE.F90 b/src/ALE/MOM_ALE.F90 index 543d77a0f3..a083402fde 100644 --- a/src/ALE/MOM_ALE.F90 +++ b/src/ALE/MOM_ALE.F90 @@ -40,7 +40,7 @@ module MOM_ALE use MOM_remapping, only : remapping_core_h, remapping_core_w use MOM_remapping, only : remappingSchemesDoc, remappingDefaultScheme use MOM_remapping, only : interpolate_column, reintegrate_column -use MOM_remapping, only : remapping_CS, dzFromH1H2 +use MOM_remapping, only : remapping_CS, dzFromH1H2, remapping_set_param use MOM_string_functions, only : uppercase, extractWord, extract_integer use MOM_tracer_registry, only : tracer_registry_type, tracer_type, MOM_tracer_chkinv use MOM_unit_scaling, only : unit_scale_type @@ -147,6 +147,7 @@ module MOM_ALE public pre_ALE_adjustments public ALE_remap_init_conds public ALE_register_diags +public ALE_set_extrap_boundaries !

This bug is corrected when the new runtime parameter MEKE_GM_SRC_ALT_SLOPE_BUG is false. Additionally there is a new runtime parameter MEKE_GM_SRC_ANSWER_DATE that specifies the use of rotationally symmetric expressions for PE_release_h when it is set to 20240601 or higher, but it should be noted that rotational symmetry also requires that MEKE_GM_SRC_ALT_SLOPE_BUG is false. Four new checksum calls were also added to verify the correctness of the calculation of MEKE%GM_src when MEKE_GM_SRC_ALT and DEBUG are true.

The expression `#if (defined a)` could not be parsed due to poor ad-hoc handling of parentheses, making it impossible to build the AM2-based coupled models with makedep, The tool has has been significantly overhauled to include better overall unary operator support. * `defined` is now more of an operation than an exception, since it is pushed to the stack like any other operator. * Parentheses are now handled as "operators", with `)` triggering an operator stack push and `(` conducting the actual operation (in this case simply returning the contents). * In order to handle the possibility of macros within parentheses, macros are now evaluated only immediately before used in expressions, rather than the instant they are first encountered. This redesign has allowed for many edge cases to be consolidated into the general purpose parser, greatly simplifying the code. --- ac/makedep | 94 +++++++++++++++++++++++++----------------------------- 1 file changed, 43 insertions(+), 51 deletions(-) diff --git a/ac/makedep b/ac/makedep index 4c9cc9229b..e0d350857e 100755 --- a/ac/makedep +++ b/ac/makedep @@ -34,6 +34,8 @@ re_procedure = re.compile( # Preprocessor expression tokenization +# NOTE: Labels and attributes could be assigned here, but for now we just use +# the token string as the label. cpp_scanner = re.Scanner([ (r'defined', lambda scanner, token: token), (r'[_A-Za-z][_0-9a-zA-Z]*', lambda scanner, token: token), @@ -56,13 +58,15 @@ cpp_scanner = re.Scanner([ (r'&', lambda scanner, token: token), (r'\|\|', lambda scanner, token: token), (r'\|', lambda scanner, token: token), - (r'^\#if', None), + (r'^ *\# *if', None), (r'\s+', None), ]) cpp_operate = { + '(': lambda x: x, '!': lambda x: not x, + 'defined': lambda x, y: x in y, '*': lambda x, y: x * y, '/': lambda x, y: x // y, '+': lambda x, y: x + y, @@ -85,6 +89,7 @@ cpp_operate = { cpp_op_rank = { '(': 13, '!': 12, + 'defined': 12, '*': 11, '/': 11, '+': 10, @@ -527,7 +532,7 @@ def cpp_expr_eval(expr, macros=None): if macros is None: macros = {} - results, remainder = cpp_scanner.scan(expr) + results, remainder = cpp_scanner.scan(expr.strip()) # Abort if any characters are not tokenized if remainder: @@ -545,72 +550,59 @@ def cpp_expr_eval(expr, macros=None): tokens = iter(results) for tok in tokens: - # Evaluate "defined()" statements - if tok == 'defined': - tok = next(tokens) - - parens = tok == '(' - if parens: - tok = next(tokens) + if tok in cpp_op_rank.keys(): + while cpp_op_rank[tok] <= cpp_op_rank[prior_op]: - # NOTE: Any key in `macros` is considered to be set, even if the - # value is None. - value = tok in macros + # Unary operators are "look ahead" so we always skip them. + # (However, `op` below could be a unary operator.) + if tok in ('!', 'defined', '('): + break - # Negation - while prior_op == '!': + second = stack.pop() op = stack.pop() - assert op == '!' - value = cpp_operate[op](value) - prior_op = stack[-1] if stack else None - - stack.append(value) - if parens: - tok = next(tokens) - assert tok == ')' + if op == '(': + value = second - elif tok.isdigit(): - value = int(tok) - stack.append(value) + elif op == '!': + if isinstance(second, str): + if second.isidentifier(): + second = macros.get(second, '0') + if second.isdigit(): + second = int(second) - elif tok.isidentifier(): - # "Identifiers that are not macros, which are all considered to be - # the number zero."

This commit includes several changes to publicly visible interfaces, and it will change answers with USE_QG_LEITH_VISC = True (which had previously triggered a fatal error), but answers and output are bitwise identical in other cases. --- src/core/MOM.F90 | 10 +- src/core/MOM_dynamics_split_RK2.F90 | 9 +- src/core/MOM_dynamics_split_RK2b.F90 | 9 +- src/core/MOM_dynamics_unsplit.F90 | 2 +- src/core/MOM_dynamics_unsplit_RK2.F90 | 2 +- .../lateral/MOM_hor_visc.F90 | 68 ++++++----- .../lateral/MOM_lateral_mixing_coeffs.F90 | 108 +++++++++++------- 7 files changed, 127 insertions(+), 81 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index fb53c638db..0b602be944 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -3114,10 +3114,10 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, & if (CS%debug) then call uvchksum("Post ALE adjust init cond [uv]", CS%u, CS%v, G%HI, haloshift=1) - call hchksum(CS%h, "Post ALE adjust init cond h", G%HI, haloshift=1, scale=GV%H_to_MKS) + call hchksum(CS%h, "Post ALE adjust init cond h", G%HI, haloshift=2, scale=GV%H_to_MKS) if (use_temperature) then - call hchksum(CS%tv%T, "Post ALE adjust init cond T", G%HI, haloshift=1, scale=US%C_to_degC) - call hchksum(CS%tv%S, "Post ALE adjust init cond S", G%HI, haloshift=1, scale=US%S_to_ppt) + call hchksum(CS%tv%T, "Post ALE adjust init cond T", G%HI, haloshift=2, scale=US%C_to_degC) + call hchksum(CS%tv%S, "Post ALE adjust init cond S", G%HI, haloshift=2, scale=US%S_to_ppt) endif endif endif @@ -3221,13 +3221,13 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, & if (CS%split) then allocate(eta(SZI_(G),SZJ_(G)), source=0.0) if (CS%use_alt_split) then - call initialize_dyn_split_RK2b(CS%u, CS%v, CS%h, CS%uh, CS%vh, eta, Time, & + call initialize_dyn_split_RK2b(CS%u, CS%v, CS%h, CS%tv, CS%uh, CS%vh, eta, Time, & G, GV, US, param_file, diag, CS%dyn_split_RK2b_CSp, restart_CSp, & CS%dt, CS%ADp, CS%CDp, MOM_internal_state, CS%VarMix, CS%MEKE, & CS%thickness_diffuse_CSp, CS%OBC, CS%update_OBC_CSp, CS%ALE_CSp, CS%set_visc_CSp, & CS%visc, dirs, CS%ntrunc, CS%pbv, calc_dtbt=calc_dtbt, cont_stencil=CS%cont_stencil) else - call initialize_dyn_split_RK2(CS%u, CS%v, CS%h, CS%uh, CS%vh, eta, Time, & + call initialize_dyn_split_RK2(CS%u, CS%v, CS%h, CS%tv, CS%uh, CS%vh, eta, Time, & G, GV, US, param_file, diag, CS%dyn_split_RK2_CSp, restart_CSp, & CS%dt, CS%ADp, CS%CDp, MOM_internal_state, CS%VarMix, CS%MEKE, & CS%thickness_diffuse_CSp, CS%OBC, CS%update_OBC_CSp, CS%ALE_CSp, CS%set_visc_CSp, & diff --git a/src/core/MOM_dynamics_split_RK2.F90 b/src/core/MOM_dynamics_split_RK2.F90 index 0557ec7cd5..a184cf473f 100644 --- a/src/core/MOM_dynamics_split_RK2.F90 +++ b/src/core/MOM_dynamics_split_RK2.F90 @@ -840,7 +840,7 @@ subroutine step_MOM_dyn_split_RK2(u_inst, v_inst, h, tv, visc, Time_local, dt, f if (CS%debug) then call MOM_state_chksum("Predictor ", up, vp, hp, uh, vh, G, GV, US, symmetric=sym) call uvchksum("Predictor avg [uv]", u_av, v_av, G%HI, haloshift=1, symmetric=sym, scale=US%L_T_to_m_s) - call hchksum(h_av, "Predictor avg h", G%HI, haloshift=0, scale=GV%H_to_MKS) + call hchksum(h_av, "Predictor avg h", G%HI, haloshift=2, scale=GV%H_to_MKS) !

A deeper investigation suggested that the compiler was attempting to deallocate a nullified pointer during automatic cleanup of RK2->SAL->sht. Apparently deallocation of a NULL pointer is an error (even though free() is not supposed to care). By redefining `sht` as an allocatable component rather than a local component of the SAL_CS instance, it seemed to satisfy the compiler that nothing was needed and the error went away. There are still some lingering questions behind the cause of the segfault, but for now I am going to put this under "compiler bug". This patch also initializes some of the logical flags in the SAL_CS type. This is possibly unnecessary, but it is consistent with the general rules of safety followed in other MOM6 derived types. --- .../lateral/MOM_self_attr_load.F90 | 16 +++++++++++----- 1 file changed, 11 insertions(+), 5 deletions(-) diff --git a/src/parameterizations/lateral/MOM_self_attr_load.F90 b/src/parameterizations/lateral/MOM_self_attr_load.F90 index 7f7215c9d8..e7f8a73ab2 100644 --- a/src/parameterizations/lateral/MOM_self_attr_load.F90 +++ b/src/parameterizations/lateral/MOM_self_attr_load.F90 @@ -20,14 +20,17 @@ module MOM_self_attr_load !> The control structure for the MOM_self_attr_load module type, public :: SAL_CS ; private - logical :: use_sal_scalar !< If true, use the scalar approximation to calculate SAL. - logical :: use_sal_sht !< If true, use online spherical harmonics to calculate SAL - logical :: use_tidal_sal_prev !< If true, read the tidal SAL from the previous iteration of - !! the tides to facilitate convergence. + logical :: use_sal_scalar = .false. + !< If true, use the scalar approximation to calculate SAL. + logical :: use_sal_sht = .false. + !< If true, use online spherical harmonics to calculate SAL + logical :: use_tidal_sal_prev = .false. + !< If true, read the tidal SAL from the previous iteration of the tides to + !! facilitate convergence. real :: sal_scalar_value !< The constant of proportionality between sea surface height !!

This is fixed by introducing a simple tokenizer which extracts <, (, and whitespace from the output , then rebuilds the records by combining any whitespace which appears inside of delimiters. This patch should hopefully resolve the CI errors in GitHub Actions. --- .testing/tools/parse_perf.py | 60 +++++++++++++++++++++++++++++++++--- 1 file changed, 55 insertions(+), 5 deletions(-) diff --git a/.testing/tools/parse_perf.py b/.testing/tools/parse_perf.py index 7cbffd995d..76c6be5bcb 100755 --- a/.testing/tools/parse_perf.py +++ b/.testing/tools/parse_perf.py @@ -3,10 +3,20 @@ import collections import json import os +import re import shlex import subprocess import sys +perf_scanner = re.Scanner([ + (r'<', lambda scanner, token: token), + (r'>', lambda scanner, token: token), + (r'\(', lambda scanner, token: token), + (r'\)', lambda scanner, token: token), + (r'[ \t]+', lambda scanner, token: token), + (r'[^<>() \t]+', lambda scanner, token: token), +]) + def main(): desc = 'Parse perf.data and return in JSON format.' @@ -58,15 +68,55 @@ def parse_perf_report(perf_data_path): # get per-symbol count else: + tokens, remainder = perf_scanner.scan(line) + if remainder: + print('Line could not be tokenized', file=sys.stderr) + print(' line:', repr(line), file=sys.stderr) + print(' tokens:', tokens, file=sys.stderr) + print(' remainder:', remainder, file=sys.stderr) + sys.exit(os.EX_DATAERR) + + # Construct record from tokens + # (NOTE: Not a proper grammar, just dumb bracket counting) + record = [] + bracks = 0 + parens = 0 + + for tok in tokens: + if tok == '<': + bracks += 1 + + if tok == '(': + parens += 1 + + rec = record[-1] if record else None + + inside_bracket = rec and (bracks > 0 or parens > 0) + lead_rec = tok in '<(' and rec and not rec.isspace() + tail_rec = not tok.isspace() and rec and rec[-1] in '>)' + + if inside_bracket or lead_rec or tail_rec: + record[-1] += tok + else: + record.append(tok) + + if tok == '>': + bracks -= 1 + if tok == '(': + parens -= 1 + + # Strip any whitespace tokens + record = [rec for rec in record if not rec.isspace()] + try: - tokens = line.split() - symbol = tokens[2] - period = int(tokens[3]) - except ValueError: + symbol = record[2] + period = int(record[3]) + except: print("parse_perf.py: Error extracting symbol count", - file=sys.stderr) + file=sys.stderr) print("line:", repr(line), file=sys.stderr) print("tokens:", tokens, file=sys.stderr) + print("record:", record, file=sys.stderr) raise profile[event_name]['symbol'][symbol] = period From 7a2a33b59d4ec29cad31b779279e9d53856a3ffe Mon Sep 17 00:00:00 2001 From: Alistair Adcroft Date: Sat, 18 May 2024 14:09:06 -0400 Subject: [PATCH 1025/1329] Use FMS1 for MacOS builds - Given a recent incompatibility with FMS2 and gfortan 14.1 we need to revert to FMS1 for the MacOS builds. --- .github/workflows/macos-regression.yml | 2 ++ .github/workflows/macos-stencil.yml | 2 ++ 2 files changed, 4 insertions(+) diff --git a/.github/workflows/macos-regression.yml b/.github/workflows/macos-regression.yml index 422c50b68a..5e0380bcd2 100644 --- a/.github/workflows/macos-regression.yml +++ b/.github/workflows/macos-regression.yml @@ -10,6 +10,8 @@ jobs: env: CC: gcc FC: gfortran + FMS_COMMIT: 2019.01.03 + FRAMEWORK: fms1 defaults: run: diff --git a/.github/workflows/macos-stencil.yml b/.github/workflows/macos-stencil.yml index 36a5841bb2..e54912b607 100644 --- a/.github/workflows/macos-stencil.yml +++ b/.github/workflows/macos-stencil.yml @@ -10,6 +10,8 @@ jobs: env: CC: gcc FC: gfortran + FMS_COMMIT: 2019.01.03 + FRAMEWORK: fms1 defaults: run: From b32aea7bf3f9e2a774afa23d3386c88156cd1182 Mon Sep 17 00:00:00 2001 From: Daniel Sarmiento <42810219+dpsarmie@users.noreply.github.com> Date: Tue, 21 May 2024 13:46:30 -0400 Subject: [PATCH 1026/1329] Add end of run restart functionality to MOM6 (#133) * Update mom_cap.F90 to add end of run restart file functionality controlled by write_restart_at_endofrun configuration option in CMEPS.

This is motivated by incredibly slow file access times on GFDL's GPFS file system (F5), with the Nvidia builds taking a prohibitively long time (around 4 hours). Compiling in $HOME reduces Nvidia times to 15 minutes, with similar reduction times in the other compilation. This is achieved with only minimal changes to the build system. Instead of creating `build/`, we create a dedicated directory in `$HOME/ci/$CI_PROJECT_ID/build` and a symbolic link to this directory in the GPFS directory. To support these builds, additional symlinks to `src/` and `ocean_only/` (for static builds) are also created, from $HOME and back into GPFS. Once the job is completed, the temporary space in $HOME is deleted. This patch should not be considered a permanent solution, it is only meant to get us through a difficult period of testing. Hopefully we can revert this change in the near future. --- .gitlab-ci.yml | 3 +++ .gitlab/pipeline-ci-tool.sh | 7 +++++++ 2 files changed, 10 insertions(+) diff --git a/.gitlab-ci.yml b/.gitlab-ci.yml index 2c4d92c424..55494696ae 100644 --- a/.gitlab-ci.yml +++ b/.gitlab-ci.yml @@ -32,6 +32,8 @@ p:clone: tags: - ncrc5 script: + # NOTE: We could sweep any builds older than 3 days here if needed + #- find $HOME/ci/[0-9]* -mtime +3 -delete 2> /dev/null || true - .gitlab/pipeline-ci-tool.sh create-job-dir #.gitlab/pipeline-ci-tool.sh clean-job-dir @@ -353,4 +355,5 @@ cleanup: before_script: - echo Skipping usual preamble script: + - rm -rf $HOME/ci/$CI_PIPELINE_ID - rm -rf $JOB_DIR diff --git a/.gitlab/pipeline-ci-tool.sh b/.gitlab/pipeline-ci-tool.sh index 77409d29ef..d948b72008 100755 --- a/.gitlab/pipeline-ci-tool.sh +++ b/.gitlab/pipeline-ci-tool.sh @@ -94,6 +94,13 @@ create-job-dir () { make -f tools/MRS/Makefile.clone clone_gfdl -j # Extras and link to datasets bash tools/MRS/generate_manifest.sh . tools/MRS/excluded-expts.txt > manifest.mk mkdir -p results + # Temporarily move build directory to $HOME to circumvent poor F5 performance + mkdir -p $HOME/ci/$CI_PIPELINE_ID/build + ln -s $HOME/ci/$CI_PIPELINE_ID/build build + # Builds need non-mangled access to src/. + ln -s "$(pwd)"/src $HOME/ci/$CI_PIPELINE_ID/src + # Static builds need access to ocean_only/ + ln -s "$(pwd)"/ocean_only $HOME/ci/$CI_PIPELINE_ID/ocean_only fi section-end create-job-dir } From 758b5a340c25c293bbd3c5436819cac1b290c4ff Mon Sep 17 00:00:00 2001 From: Claire Yung Date: Wed, 24 Apr 2024 13:08:47 -0400 Subject: [PATCH 1028/1329] Add maximum number of iterations in find_depth_of_pressure_in_cell --- src/core/MOM_density_integrals.F90 | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/src/core/MOM_density_integrals.F90 b/src/core/MOM_density_integrals.F90 index b73524e362..d747d6aab2 100644 --- a/src/core/MOM_density_integrals.F90 +++ b/src/core/MOM_density_integrals.F90 @@ -1753,6 +1753,7 @@ subroutine find_depth_of_pressure_in_cell(T_t, T_b, S_t, S_b, z_t, z_b, P_t, P_t real :: F_guess, F_l, F_r !

At one point in the code, the former were being used where the latter were more appropriate. This commit changes this to help with the understandability of the code. However, when the order of arithmetic is not specified with parentheses, the Nvidia compiler is changing answers with this change of variables. To avoid this change in answers, this commit is only changing which variables are used when the answer_date is larger than 20190101 and the order of the sums are specified with parentheses.

This change includes reading in the maximum depth and beta, and using them to calculate the equatorial deformation radius and the external gravity wave speed. The references to the papers describing the test case in the module were added to the doxygen comments describing the routines in this module. This commit also includes adding comments documenting the nature and units of all the internal variables in this module. There are two new arguments each (param_file and just_read) to soliton_initialize_thickness and soliton_initialize_velocity to accommodate these changes, bringing them into line with the interfaces for other similar user initialization routines, and MOM_initialize_state was changed accordingly. This change could change answers in general, but in the specific examples that use this code, both beta and the external wave speed are deliberately set to 1 in MKS units, so this commit does not change answers for that specific case. --- .../MOM_state_initialization.F90 | 5 +- src/user/soliton_initialization.F90 | 108 +++++++++++++++--- 2 files changed, 94 insertions(+), 19 deletions(-) diff --git a/src/initialization/MOM_state_initialization.F90 b/src/initialization/MOM_state_initialization.F90 index 4f11233c93..c18752c83d 100644 --- a/src/initialization/MOM_state_initialization.F90 +++ b/src/initialization/MOM_state_initialization.F90 @@ -343,7 +343,8 @@ subroutine MOM_initialize_state(u, v, h, tv, Time, G, GV, US, PF, dirs, & just_read=just_read) case ("dumbbell"); call dumbbell_initialize_thickness(dz, depth_tot, G, GV, US, PF, & just_read=just_read) - case ("soliton"); call soliton_initialize_thickness(dz, depth_tot, G, GV, US) + case ("soliton"); call soliton_initialize_thickness(dz, depth_tot, G, GV, US, PF, & + just_read=just_read) case ("phillips"); call Phillips_initialize_thickness(dz, depth_tot, G, GV, US, PF, & just_read=just_read) case ("rossby_front") @@ -508,7 +509,7 @@ subroutine MOM_initialize_state(u, v, h, tv, Time, G, GV, US, PF, dirs, & case ("phillips"); call Phillips_initialize_velocity(u, v, G, GV, US, PF, just_read) case ("rossby_front"); call Rossby_front_initialize_velocity(u, v, h, & G, GV, US, PF, just_read) - case ("soliton"); call soliton_initialize_velocity(u, v, G, GV, US) + case ("soliton"); call soliton_initialize_velocity(u, v, G, GV, US, PF, just_read) case ("USER"); call user_initialize_velocity(u, v, G, GV, US, PF, just_read) case default ; call MOM_error(FATAL, "MOM_initialize_state: "//& "Unrecognized velocity configuration "//trim(config)) diff --git a/src/user/soliton_initialization.F90 b/src/user/soliton_initialization.F90 index 06a781ec94..722a41b7e5 100644 --- a/src/user/soliton_initialization.F90 +++ b/src/user/soliton_initialization.F90 @@ -26,8 +26,9 @@ module soliton_initialization contains -!> Initialization of thicknesses in Equatorial Rossby soliton test -subroutine soliton_initialize_thickness(h, depth_tot, G, GV, US) +!> Initialization of thicknesses in equatorial Rossby soliton test, as described in section +!! 6.1 of Haidvogel and Beckman (1990) and in Boyd (1980, JPO) and Boyd (1985, JPO). +subroutine soliton_initialize_thickness(h, depth_tot, G, GV, US, param_file, just_read) type(ocean_grid_type), intent(in) :: G !< The ocean's grid structure. type(verticalGrid_type), intent(in) :: GV !< The ocean's vertical grid structure. type(unit_scale_type), intent(in) :: US !< A dimensional unit scaling type @@ -35,45 +36,96 @@ subroutine soliton_initialize_thickness(h, depth_tot, G, GV, US) intent(out) :: h !< The thickness that is being initialized [Z ~> m] real, dimension(SZI_(G),SZJ_(G)), & intent(in) :: depth_tot !< The nominal total depth of the ocean [Z ~> m] + type(param_file_type), intent(in) :: param_file !< A structure indicating the open file + !! to parse for model parameter values. + logical, intent(in) :: just_read !< If true, this call will only read + !! parameters without changing h. + !

Also moved 5 allocatable arrays (KPP_NLTheat, KPP_NLTscalar, KPP_buoy_flux, KPP_temp_flux and KPP_salt_flux) out of diabatic_CS, replacing them with ordinary arrays in diabatic_ALE(), diabatic_ALE_legacy() and layered_diabatic(). This change could reduce the high-water memory footprint of the model when KPP is in use. All answers are bitwise identical, but one element of a publicly visible type has been eliminated. --- src/core/MOM_forcing_type.F90 | 3 +- .../vertical/MOM_diabatic_driver.F90 | 149 ++++++++---------- 2 files changed, 70 insertions(+), 82 deletions(-) diff --git a/src/core/MOM_forcing_type.F90 b/src/core/MOM_forcing_type.F90 index 452161c6ca..72c67253ed 100644 --- a/src/core/MOM_forcing_type.F90 +++ b/src/core/MOM_forcing_type.F90 @@ -126,9 +126,8 @@ module MOM_forcing_type real, pointer, dimension(:,:) :: & netMassIn => NULL(), & !< Sum of water mass fluxes into the ocean integrated over a !! forcing timestep [H ~> m or kg m-2] - netMassOut => NULL(), & !< Net water mass flux out of the ocean integrated over a forcing timestep, + netMassOut => NULL() !< Net water mass flux out of the ocean integrated over a forcing timestep, !! with negative values for water leaving the ocean [H ~> m or kg m-2] - KPP_salt_flux => NULL() !< KPP effective salt flux [ppt m s-1] ! heat associated with water crossing ocean surface real, pointer, dimension(:,:) :: & diff --git a/src/parameterizations/vertical/MOM_diabatic_driver.F90 b/src/parameterizations/vertical/MOM_diabatic_driver.F90 index 081f065f3e..010f17b978 100644 --- a/src/parameterizations/vertical/MOM_diabatic_driver.F90 +++ b/src/parameterizations/vertical/MOM_diabatic_driver.F90 @@ -244,15 +244,6 @@ module MOM_diabatic_driver type(group_pass_type) :: pass_hold_eb_ea !< For group halo pass type(group_pass_type) :: pass_Kv !< For group halo pass type(diag_grid_storage) :: diag_grids_prev!< Stores diagnostic grids at some previous point in the algorithm - !

To accommodate these changes there is now a call to convert_MLD_to_ML_thickness inside of call_tracer_column_fns. The thermo_var_ptrs type argument (tv) to ideal_age_tracer_column_physics and count_BL_layers are no longer used and have been removed. All answers are bitwise identical in Boussinesq mode, but in non-Boussinesq mode there are changes in the passive ideal age tracers at the level of roundoff. There are also changes in the units of arguments and the number of arguments to a public interface. --- src/tracer/MOM_tracer_flow_control.F90 | 27 +++++++++++++++--------- src/tracer/ideal_age_example.F90 | 29 +++++++++++--------------- 2 files changed, 29 insertions(+), 27 deletions(-) diff --git a/src/tracer/MOM_tracer_flow_control.F90 b/src/tracer/MOM_tracer_flow_control.F90 index 6d035e1d27..10aba675da 100644 --- a/src/tracer/MOM_tracer_flow_control.F90 +++ b/src/tracer/MOM_tracer_flow_control.F90 @@ -11,6 +11,7 @@ module MOM_tracer_flow_control use MOM_get_input, only : Get_MOM_input use MOM_grid, only : ocean_grid_type use MOM_hor_index, only : hor_index_type +use MOM_interface_heights, only : convert_MLD_to_ML_thickness use MOM_CVMix_KPP, only : KPP_CS use MOM_open_boundary, only : ocean_OBC_type use MOM_restart, only : MOM_restart_CS @@ -427,7 +428,7 @@ subroutine call_tracer_set_forcing(sfc_state, fluxes, day_start, day_interval, G end subroutine call_tracer_set_forcing !> This subroutine calls all registered tracer column physics subroutines. -subroutine call_tracer_column_fns(h_old, h_new, ea, eb, fluxes, Hml, dt, G, GV, US, tv, optics, CS, & +subroutine call_tracer_column_fns(h_old, h_new, ea, eb, fluxes, mld, dt, G, GV, US, tv, optics, CS, & debug, KPP_CSp, nonLocalTrans, evap_CFL_limit, minimum_forcing_depth) type(ocean_grid_type), intent(in) :: G !< The ocean's grid structure. type(verticalGrid_type), intent(in) :: GV !< The ocean's vertical grid structure. @@ -444,7 +445,7 @@ subroutine call_tracer_column_fns(h_old, h_new, ea, eb, fluxes, Hml, dt, G, GV, type(forcing), intent(in) :: fluxes !< A structure containing pointers to !! any possible forcing fields. !!

This code rearrangement changes answers in non-Boussinesq mode because the layer specific volumes will have evolved between these two calls, but it is consistent with the mixed layer thicknesses as used in the boundary layer parameterizations. A new argument was added to bulkmixedlayer to return the mixed layer thickness that was already being calculated. The previous argument Hml was renamed to BLD and changed from a pointer into a simple array. Both are intent(inout) rather than intent(out) to preserve values in halos. This commit also revises the logic around the allocation of visc%h_ML and its registration as a restart variable, including handling cases where an older restart file is being read that includes MLD but not h_ML. Because the mixed layer depth is used in almost cases, CS%Hml in the control structure for MOM.F90 was changed from a pointer to an allocatable, with values of 0 in those cases (e.g., when ADIABATIC is true) where it is not used. In addition, the argument Hml to the various diabatic routines was changed to MLD to more clearly reflect that it is a depth and not a thickness. Outside of diabatic, BML is only used to provide the tracer point boundary layer depths to the calling routines, so it does not need a halo update. Instead, all of the halo updates for the various elements of visc that do need halo updates after the diabatic calls are collected into one place for efficiency and more accurate timings. The scale arguments of 34 checksum calls were revised from GV%H_to_m to GV%H_to_MKS for more accurate checksums in non-Boussinesq configurations by avoiding multiplication by an reference specific volume, and instead only rescaling by an integer power of 2. All answers are bitwise identical in Boussinesq mode, but in non-Boussinesq mode there are changes in answers in cases that use the boundary layer thicknesses obtained from the boundary layer parameterizations in subsequent calculations, such as mixed layer restratification with some options. There are also changes to the arguments of several publicly visible routines. --- src/core/MOM.F90 | 36 ++-- .../vertical/MOM_bulk_mixed_layer.F90 | 41 ++-- .../vertical/MOM_diabatic_driver.F90 | 198 ++++++++---------- .../vertical/MOM_set_viscosity.F90 | 7 +- 4 files changed, 138 insertions(+), 144 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 0f3274c2f3..ad26b10013 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -98,7 +98,6 @@ module MOM use MOM_hor_index, only : hor_index_type, hor_index_init use MOM_hor_index, only : rotate_hor_index use MOM_interface_heights, only : find_eta, calc_derived_thermo, thickness_to_dz -use MOM_interface_heights, only : convert_MLD_to_ML_thickness use MOM_interface_filter, only : interface_filter, interface_filter_init, interface_filter_end use MOM_interface_filter, only : interface_filter_CS use MOM_internal_tides, only : int_tide_CS @@ -212,8 +211,8 @@ module MOM real ALLOCABLE_, dimension(NIMEM_,NJMEM_) :: eta_av_bc !< free surface height or column mass time averaged over the last !! baroclinic dynamics time step [H ~> m or kg m-2] - real, dimension(:,:), pointer :: & - Hml => NULL() !< active mixed layer depth [Z ~> m] + real, dimension(:,:), pointer :: Hml => NULL() + !< active mixed layer depth, or 0 if there is no boundary layer scheme [Z ~> m] real :: time_in_cycle !< The running time of the current time-stepping cycle !! in calls that step the dynamics, and also the length of !! the time integral of ssh_rint [T ~> s]. @@ -1328,10 +1327,6 @@ subroutine step_MOM_dynamics(forces, p_surf_begin, p_surf_end, dt, dt_thermo, & CS%uhtr, CS%vhtr, G%HI, haloshift=0, scale=GV%H_to_MKS*US%L_to_m**2) endif call cpu_clock_begin(id_clock_ml_restrat) - if (associated(CS%visc%MLD)) then - call safe_alloc_ptr(CS%visc%h_ML, G%isd, G%ied, G%jsd, G%jed) - call convert_MLD_to_ML_thickness(CS%visc%MLD, h, CS%visc%h_ML, CS%tv, G, GV, halo=1) - endif call mixedlayer_restrat(h, CS%uhtr, CS%vhtr, CS%tv, forces, dt, CS%visc%MLD, CS%visc%h_ML, & CS%visc%sfc_buoy_flx, CS%VarMix, G, GV, US, CS%mixedlayer_restrat_CSp) call cpu_clock_end(id_clock_ml_restrat) @@ -2129,6 +2124,7 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, & logical :: Boussinesq !

Answers are bitwise identical for Boussinesq cases, but they will change in non-Boussinesq cases because the layer specific volumes have changed between the time the boundary layer thicknesses have been calculated and when they are being used in the brine plume parameterization. Also use visc%h_ML in place of calls to KPP_get_BLD or energetic_PBL_get_MLD in step_MOM_dyn_split_RK2, hor_bnd_diffusion and neutral_diffusion_calc_coeffs. This change requires a new vertvisc_type argument to tracer_hordiff, hor_bnd_diffusion and neutral_diffusion_calc_coeffs. Boussinesq answers are bitwise identical, but non-Boussinesq answers change because they now use the actual model specific volumes rather than some prescribed constant value to to the relevant unit conversions. The logic in set_visc_register_restarts was also updated so that visc%MLD and visc%h_ML are allocated and registered for restarts in the cases where they will be used. All answers are bitwise identical in Boussinesq mode, but in non-Boussinesq mode there are changes in answers in cases that use neutral tracer diffusion that excludes the boundary layer, horizontal tracer diffusion in the boundary layer or FPMIX. There are also changes to the arguments of several publicly visible routines. --- src/core/MOM.F90 | 8 ++-- src/core/MOM_dynamics_split_RK2.F90 | 9 +---- src/core/MOM_dynamics_split_RK2b.F90 | 9 +---- .../vertical/MOM_CVMix_ddiff.F90 | 4 +- .../vertical/MOM_diabatic_aux.F90 | 39 +++++++------------ .../vertical/MOM_diabatic_driver.F90 | 8 ++-- .../vertical/MOM_set_viscosity.F90 | 29 +++++++++++--- src/tracer/MOM_hor_bnd_diffusion.F90 | 24 ++++++++---- src/tracer/MOM_neutral_diffusion.F90 | 18 ++++++--- src/tracer/MOM_tracer_hor_diff.F90 | 17 ++++---- 10 files changed, 88 insertions(+), 77 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index ad26b10013..e6a42ef7a7 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -1433,7 +1433,7 @@ subroutine step_MOM_tracer_dyn(CS, G, GV, US, h, Time_local) call advect_tracer(h, CS%uhtr, CS%vhtr, CS%OBC, CS%t_dyn_rel_adv, G, GV, US, & CS%tracer_adv_CSp, CS%tracer_Reg, x_first_in=x_first) if (CS%debug) call MOM_tracer_chksum("Post-advect ", CS%tracer_Reg, G) - call tracer_hordiff(h, CS%t_dyn_rel_adv, CS%MEKE, CS%VarMix, G, GV, US, & + call tracer_hordiff(h, CS%t_dyn_rel_adv, CS%MEKE, CS%VarMix, CS%visc, G, GV, US, & CS%tracer_diff_CSp, CS%tracer_Reg, CS%tv) if (CS%debug) call MOM_tracer_chksum("Post-diffuse ", CS%tracer_Reg, G) if (showCallTree) call callTree_waypoint("finished tracer advection/diffusion (step_MOM)") @@ -1882,7 +1882,7 @@ subroutine step_offline(forces, fluxes, sfc_state, Time_start, time_interval, CS call calc_depth_function(G, CS%VarMix) call calc_slope_functions(CS%h, CS%tv, dt_offline, G, GV, US, CS%VarMix, OBC=CS%OBC) endif - call tracer_hordiff(CS%h, dt_offline, CS%MEKE, CS%VarMix, G, GV, US, & + call tracer_hordiff(CS%h, dt_offline, CS%MEKE, CS%VarMix, CS%visc, G, GV, US, & CS%tracer_diff_CSp, CS%tracer_Reg, CS%tv) endif endif @@ -1909,7 +1909,7 @@ subroutine step_offline(forces, fluxes, sfc_state, Time_start, time_interval, CS call calc_depth_function(G, CS%VarMix) call calc_slope_functions(CS%h, CS%tv, dt_offline, G, GV, US, CS%VarMix, OBC=CS%OBC) endif - call tracer_hordiff(CS%h, dt_offline, CS%MEKE, CS%VarMix, G, GV, US, & + call tracer_hordiff(CS%h, dt_offline, CS%MEKE, CS%VarMix, CS%visc, G, GV, US, & CS%tracer_diff_CSp, CS%tracer_Reg, CS%tv) endif endif @@ -1966,7 +1966,7 @@ subroutine step_offline(forces, fluxes, sfc_state, Time_start, time_interval, CS CS%h, eatr, ebtr, uhtr, vhtr) !

This includes the introduction of 18 new runtime variables to replace hard-coded dimensional constants and two runtime logical flags to reproduce existing bugs. An inconsistency in the sign convention for the distance from the hurricane center with idealized_hurricane_wind_forcing in (the probably not yet used) single column mode was also corrected. Also added descriptions with units for all the variables in this module. By default or with appropriate parameter settings all answers are bitwise identical. --- src/user/Idealized_Hurricane.F90 | 564 +++++++++++++++++++++---------- 1 file changed, 380 insertions(+), 184 deletions(-) diff --git a/src/user/Idealized_Hurricane.F90 b/src/user/Idealized_Hurricane.F90 index 0c9d5cd330..c47366b23c 100644 --- a/src/user/Idealized_Hurricane.F90 +++ b/src/user/Idealized_Hurricane.F90 @@ -13,10 +13,9 @@ module Idealized_hurricane !

While rescaling this value is unphysical, this adjustment can be thought of as not allowing shear instabilities to grow up to the full distance to the nearest boundary because of other turbulent processes which would disrupt their growth. * Rename parameter and swtich to multiplication Rename the parameter beta to lz_rescale to be more descriptive. To avoid two divisions in a single line, the inverse of lz_rescale is calculated and stored as I_lz_rescale_sqr. Where the calculation is done logic has been added to check that lz_rescale is greater than zero to avoid dividing by zero or making lz_rescale negative. * Add Comment where lz_rescale is used Based on Wei's suggestion, add a comment where lz_rescale is used and put the multiplication by I_lz_rescale to the next line. * Remove Trailing whitespace --------- Co-authored-by: Theresa Morrison Co-authored-by: Theresa Morrison Co-authored-by: Theresa Morrison Co-authored-by: Theresa Morrison --- .../vertical/MOM_kappa_shear.F90 | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/src/parameterizations/vertical/MOM_kappa_shear.F90 b/src/parameterizations/vertical/MOM_kappa_shear.F90 index 8a1974d8ea..dac8508b4d 100644 --- a/src/parameterizations/vertical/MOM_kappa_shear.F90 +++ b/src/parameterizations/vertical/MOM_kappa_shear.F90 @@ -54,6 +54,10 @@ module MOM_kappa_shear real :: lambda2_N_S !< The square of the ratio of the coefficients of !! the buoyancy and shear scales in the diffusivity !! equation, 0 to eliminate the shear scale [nondim]. + real :: lz_rescale !< A coefficient to rescale the distance to the nearest + !! solid boundary.

Units were added to comments describing about 79 real variables in 4 framework modules, atmos_ocean_fluxes.F90 for 2 drivers, MOM_oda_incupd.F90, MOM_oda_driver.F90 and MOM_variables.F90. The variable nhours_incupd in initialize_oda_incupd was renamed to incupd_timescale and the factor of 3600.0 that converts ODA_INCUPD_NHOURS from hours into seconds was moved from where this variable is used into the scale argument where it is set to help document the meaning and units of this variable as simply and clearly as possible. The unused variable smb was removed from Shelf_main in ice_shelf_driver.F90. The internal variable tmp in RGC_initialize_sponges was renamed rho to reflect its contents, and its contents and units are now described in a comment. Although the units have been added to the description in MEKE_vec as though it is being used in a dimensionally consistent way, I suspect that this might actually be in MKS units, in which case a unit conversion factor might be needed, and a comment has been added to note this. However, the machine learning code that is used to set this array comes from an external package that is not being used yet at GFDL, so it is not clear what code should be examined to address this question. A comment was added in set_up_global_tgrid noting a unit rescaling factor that appears to be missing from a dimensional constant. All answers are bitwise identical, and for the most part only comments are changed, although two internal variables were renamed. --- .../ice_solo_driver/atmos_ocean_fluxes.F90 | 7 ++- .../ice_solo_driver/ice_shelf_driver.F90 | 1 - .../solo_driver/atmos_ocean_fluxes.F90 | 7 ++- src/core/MOM_variables.F90 | 4 +- src/framework/MOM_coms.F90 | 50 ++++++++++--------- src/framework/MOM_coupler_types.F90 | 46 ++++++++++++----- src/framework/MOM_intrinsic_functions.F90 | 8 +-- src/framework/MOM_random.F90 | 12 ++--- src/ocean_data_assim/MOM_oda_driver.F90 | 10 +++- src/ocean_data_assim/MOM_oda_incupd.F90 | 42 +++++++++------- src/parameterizations/lateral/MOM_MEKE.F90 | 10 ++-- src/user/RGC_initialization.F90 | 6 +-- 12 files changed, 124 insertions(+), 79 deletions(-) diff --git a/config_src/drivers/ice_solo_driver/atmos_ocean_fluxes.F90 b/config_src/drivers/ice_solo_driver/atmos_ocean_fluxes.F90 index 4a4ddf6da3..fb9fbe3e22 100644 --- a/config_src/drivers/ice_solo_driver/atmos_ocean_fluxes.F90 +++ b/config_src/drivers/ice_solo_driver/atmos_ocean_fluxes.F90 @@ -20,9 +20,12 @@ function aof_set_coupler_flux(name, flux_type, implementation, atm_tr_index, character(len=*), intent(in) :: flux_type !< An unused argument character(len=*), intent(in) :: implementation !< An unused argument integer, optional, intent(in) :: atm_tr_index !< An unused argument - real, dimension(:), optional, intent(in) :: param !< An unused argument + real, dimension(:), optional, intent(in) :: param !< An unused argument that would be used to + !! pass parameters for flux parameterizations + !! in other contexts [various] logical, dimension(:), optional, intent(in) :: flag !< An unused argument - real, optional, intent(in) :: mol_wt !< An unused argument + real, optional, intent(in) :: mol_wt !< An unused argument that would usually be + !! the tracer's molecular weight [g mol-1] character(len=*), optional, intent(in) :: ice_restart_file !< An unused argument character(len=*), optional, intent(in) :: ocean_restart_file !< An unused argument character(len=*), optional, intent(in) :: units !< An unused argument diff --git a/config_src/drivers/ice_solo_driver/ice_shelf_driver.F90 b/config_src/drivers/ice_solo_driver/ice_shelf_driver.F90 index 787fa7e7d1..753269116a 100644 --- a/config_src/drivers/ice_solo_driver/ice_shelf_driver.F90 +++ b/config_src/drivers/ice_solo_driver/ice_shelf_driver.F90 @@ -143,7 +143,6 @@ program Shelf_main integer :: yr, mon, day, hr, mins, sec !

The same correction was made to the slope_x and slope_y arguments returned from calc_isoneutral_slopes, and self-consistent changes were made to the overturning streamfunction calculations in thickness_diffuse_full. In addition, there were some corrections made to the documentation at the end of MOM_thickness_diffuse.F90, and the calculate_slopes argument to calc_slope_functions_using_just_e() that was always hard-coded to .true. was eliminated to avoid any confusion about whether these changes might propagate beyond the interface height diffusion calculations. This commit addresses most aspects of the issue discussed at github.com/NOAA-GFDL/MOM6/issues/359, although it does not change the sign convention for the overturning streamfunction. All solutions are bitwise identical, but there is a change in the sign convention for two diagnostics and two arguments to a publicly visible interface in pure layer mode when no equation of state is used. --- src/core/MOM_isopycnal_slopes.F90 | 12 +++--- .../lateral/MOM_lateral_mixing_coeffs.F90 | 40 ++++++------------- .../lateral/MOM_thickness_diffuse.F90 | 16 ++++---- 3 files changed, 27 insertions(+), 41 deletions(-) diff --git a/src/core/MOM_isopycnal_slopes.F90 b/src/core/MOM_isopycnal_slopes.F90 index 9defa597ab..a6949e1f40 100644 --- a/src/core/MOM_isopycnal_slopes.F90 +++ b/src/core/MOM_isopycnal_slopes.F90 @@ -356,8 +356,9 @@ subroutine calc_isoneutral_slopes(G, GV, US, h, e, tv, dt_kappa_smooth, use_stan slope = 0.0 endif else !

Also added logic that correctly determines when iterations can be stopped because no further changes occur, and rearranged to loops to avoid revisiting layers that have converged. Because the default tolerances for the temperature, salinity and density changes are set to be the same and the partial derivatives of density with temperature and salinity are less than 1 in the MKS units used here for a realistic equation of state of seawater, this bug does not impact any of the existing regression test cases, but this bug could lead to non-reproducibility with non-default values. This commit changes the entries in the MOM_parameter_doc files that have Z_INIT_ALE_REMAPPING = .false. and FIT_TO_TARGET_DENSITY_IC = .true., by adding a new runtime parameter and by not logging DETERMINE_TEMP_T_TOLERANCE and DETERMINE_TEMP_T_TOLERANCE if they are not used because DETERMINE_TEMP_CONVERGENCE_BUG is false.

The previous version had problems where the model would not run when ROTATE_INTEX = True and the CFCs (and probably other passive tracers) were being used, as noted at NOAA-GFDL/MOM6/issues/621. These problems have now been fixed. There are new calls to coupler_type_spawn() in allocate_forcing_by_ref() and allocate_surface_state() that manage the creation of the coupler_2d_bt_types for unrotated types based on information from their rotated counterparts. There is a new optional turns arguments to allocate_forcing_by_ref() and new optional sfc_state_in and turns arguments to allocate_surface_state(), and these are now being used in at least 6 places where unrotated temporary surface_state or forcing types are being set up. There are also new optional turns argument to extract_coupler_type_data() and set_coupler_type_data() that are used to deal with the fact that the internal data arrays in the coupler_bc_types are never rotated, unlike the other MOM6 arrays, because they have to be passed directly into the generic tracer code. These new turns arguments are used in 14 calls from various tracer packages, including in 6 calls from the OCMIP2_CFC code. There are 4 new calls to deallocate_surface_state() or deallocate_forcing_type() that were added to avoid (presumably minor) memory leaks when grid rotation is enabled. These new calls are in initialize_ice_shelf_fluxes(), shelf_calc_flux() and in the surface flux diagnostics section of step_MOM(). All answers are bitwise identical in any cases that worked previously, but some cases with grid rotation that previously were failing with cryptic error messages are now running successfully. There are new optional arguments to several publicly visible routines. --- src/core/MOM.F90 | 11 ++-- src/core/MOM_forcing_type.F90 | 22 ++++++-- src/core/MOM_variables.F90 | 50 ++++++++++++------ src/framework/MOM_coupler_types.F90 | 71 ++++++++++++++++++++++---- src/ice_shelf/MOM_ice_shelf.F90 | 34 +++++++----- src/tracer/DOME_tracer.F90 | 2 +- src/tracer/ISOMIP_tracer.F90 | 2 +- src/tracer/MOM_OCMIP2_CFC.F90 | 12 ++--- src/tracer/advection_test_tracer.F90 | 2 +- src/tracer/boundary_impulse_tracer.F90 | 2 +- src/tracer/dye_example.F90 | 2 +- src/tracer/ideal_age_example.F90 | 2 +- src/tracer/oil_tracer.F90 | 2 +- src/tracer/tracer_example.F90 | 2 +- 14 files changed, 157 insertions(+), 59 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 397a4e4059..42e675d41f 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -624,7 +624,7 @@ subroutine step_MOM(forces_in, fluxes_in, sfc_state, Time_start, time_int_in, CS call rotate_mech_forcing(forces_in, turns, forces) allocate(fluxes) - call allocate_forcing_type(fluxes_in, G, fluxes) + call allocate_forcing_type(fluxes_in, G, fluxes, turns=turns) call rotate_forcing(fluxes_in, fluxes, turns) else forces => forces_in @@ -1044,6 +1044,7 @@ subroutine step_MOM(forces_in, fluxes_in, sfc_state, Time_start, time_int_in, CS !

This seems to be double-counting as `visc_rem_[uv]` is accounted for in the barotropic solver vertical weights. Moreover, for options other than BT_cont, the velocity point thickness does not include visc_rem. The fix removes the visc_rem factor from h_[uv] when BT_cont is used. A runtime flag VISC_REM_CONT_HVEL_FIX is added to control the behavior of this commit. The current default is false (not applying the fix). Other small changes: * Write out explicitly all keyword arguments in `continuity`() calls in MOM_dynamics_split_RK2. * Rename a runtime parameter BAROTROPIC_VERTICAL_WEIGHT_FIX from a previous commit to VISC_REM_BT_WEIGHT_FIX, to be consistent with the style of the other two flags. * Add VISC_REM_TIMESTEP_FIX parameter to MOM_dynamics_split_RK2b --- src/core/MOM_barotropic.F90 | 2 +- src/core/MOM_continuity_PPM.F90 | 47 +++++++++++++++++++++------- src/core/MOM_dynamics_split_RK2.F90 | 9 +++--- src/core/MOM_dynamics_split_RK2b.F90 | 12 ++++++- 4 files changed, 53 insertions(+), 17 deletions(-) diff --git a/src/core/MOM_barotropic.F90 b/src/core/MOM_barotropic.F90 index abed8be16f..fb343978fc 100644 --- a/src/core/MOM_barotropic.F90 +++ b/src/core/MOM_barotropic.F90 @@ -4612,7 +4612,7 @@ subroutine barotropic_init(u, v, h, eta, Time, G, GV, US, param_file, diag, CS, default=default_answer_date, do_not_log=.not.GV%Boussinesq) if (.not.GV%Boussinesq) CS%answer_date = max(CS%answer_date, 20230701) - call get_param(param_file, mdl, "BAROTROPIC_VERTICAL_WEIGHT_FIX", CS%wt_uv_fix, & + call get_param(param_file, mdl, "VISC_REM_BT_WEIGHT_FIX", CS%wt_uv_fix, & "If true, use a normalized weight function for vertical averages of "//& "baroclinic velocity and forcing.

These anticipated changes will involve selecting an internal interface at which to define the shape of the interfaces with depth when there is an ice shelf, rather than assuming that the top surface pressure varies linearly with depth between the two top corners. In PressureForce_FV_nonBouss, this refactoring includes turning za, intx_za and inty_za into 3-d arrays and moving the code setting these arrays outside of the k-loop setting the pressure gradient forces. Changes in PressureForce_FV_Bouss are analogous but involve turning 7 arrays (pa, dpa, intz_dpa, intx_pa, intx_dpa, inty_pa and inty_dpa) into 3-d arrays. In both cases, the code for a reduced gravity model is consolidated into a single block toward the end of the routines. These changes to use more 3-d arrays could increase the computational time for the pressure gradient calculations, but in short regression tests any such increase in computational time appears to be small. No external interfaces are changed, and all answers are bitwise identical. --- src/core/MOM_PressureForce_FV.F90 | 318 +++++++++++++++++------------- 1 file changed, 181 insertions(+), 137 deletions(-) diff --git a/src/core/MOM_PressureForce_FV.F90 b/src/core/MOM_PressureForce_FV.F90 index 5fb3ade634..5d0f4ff167 100644 --- a/src/core/MOM_PressureForce_FV.F90 +++ b/src/core/MOM_PressureForce_FV.F90 @@ -128,21 +128,22 @@ subroutine PressureForce_FV_nonBouss(h, tv, PFu, PFv, G, GV, US, CS, ALE_CSp, p_ e_tide_sal, & !

This commit fixes this problem by (1) adding an extra layer to the bottom of the hard-coded WOA09 list of diagnostic depths when the ocean is deeper than the 9250 m maximum depth in that file, and (2) changing the default behavior for diagnostic grids to be be uniform when the maximum ocean depth is deeper than 9250 m, for which WOA09 is no longer likely to be a convenient choice. With this change, MOM6 no longer has segmentation faults for the configuration described in issues/491. All solutions are bitwise identical, but some z-space diagnostic grids will be modified in cases that previously had segmentation faults. --- src/ALE/MOM_regridding.F90 | 19 ++++++++++++++----- 1 file changed, 14 insertions(+), 5 deletions(-) diff --git a/src/ALE/MOM_regridding.F90 b/src/ALE/MOM_regridding.F90 index 8faec6c495..43d3f65a5e 100644 --- a/src/ALE/MOM_regridding.F90 +++ b/src/ALE/MOM_regridding.F90 @@ -211,6 +211,8 @@ subroutine initialize_regridding(CS, GV, US, max_depth, param_file, mdl, coord_m real :: tmpReal !

Setting this to true reproduces the previous solutions, while setting it to false treats negative and zero Laplacian viscosities the same way when bounding the biharmonic viscosity. When the Laplacian viscosities are all non-negative, the value of BACKSCATTER_UNDERBOUND makes no difference. The default is true for historical reasons, but this option probably should be set to false to avoid certain numerical instabilities from the horizontal viscosities.

Parentheses have been added to disable these FMAs. Calculation of the cell width fractions `L` was consolidated and moved into a new function, `find_L_open_concave_analytic` (later renamed to `find_open_L_open_concave_trigonometric`). When compiled with Intel and using the following flags, -O2 -march=core-avx2 -fp-model source -qno-opt-dynamic-align additional FMAs are added to the function, specifically the following expressions: crv_3 = (Dp + Dm - 2.0*D_vel) L(K) = L0*(1.0 + ax2_3apb*L0) L(K) = apb_4a * (1.0 - 2.0 * cos( C1_3*acos(a2x48_apb3*vol_below(K) - 1.0) - C2pi_3) ) (Third expression FMA was added inside of `acos()` by the compiler) The crucial flag seems to be `-march=core-avx2` which controls the introduction of FMAs and explains why the problem went undetected. The legacy answers were restored by adding new parentheses to the above equations. Since this function is not generally considered reproducible and is provided for legacy support, the loss of performance is not considered to be an issue. --- src/parameterizations/vertical/MOM_set_viscosity.F90 | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) diff --git a/src/parameterizations/vertical/MOM_set_viscosity.F90 b/src/parameterizations/vertical/MOM_set_viscosity.F90 index e59e5d99aa..d1d333b5ce 100644 --- a/src/parameterizations/vertical/MOM_set_viscosity.F90 +++ b/src/parameterizations/vertical/MOM_set_viscosity.F90 @@ -1178,7 +1178,8 @@ subroutine find_L_open_concave_trigonometric(vol_below, D_vel, Dp, Dm, L, GV) !

I've split out this block into a stand alone function so that we can re-use it in a to-be-written analog of remap_via_sub_cells() that will remap integrated quantities. - Added some in-line documentation of algorithm used by remap_via_sub_cells() - Added new column-wise function intersect_src_tgt_grids() - Added tests of intersect_src_tgt_grids() that check against known results - Had to add a new helper function to MOM_remapping to report state of integer arrays. --- src/ALE/MOM_remapping.F90 | 509 ++++++++++++++++++++++++++++---------- 1 file changed, 377 insertions(+), 132 deletions(-) diff --git a/src/ALE/MOM_remapping.F90 b/src/ALE/MOM_remapping.F90 index bb6ec54849..09ef896014 100644 --- a/src/ALE/MOM_remapping.F90 +++ b/src/ALE/MOM_remapping.F90 @@ -493,8 +493,6 @@ subroutine remap_via_sub_cells( n0, h0, u0, ppoly0_E, ppoly0_coefs, n1, h1, meth integer :: i_sub !

This phase as-is is only used for remapping of intensive variables but it does implicitly calculate intermediate extensive quantities which are analogous to what we need when remapping momentum. Splitting this phase out primarily allows us to test this bit of code and it has indeed revealed an edge case that fails. - Added new column-wise function remap_src_to_sub_grid() - Added tests of remap_src_to_sub_grid() that check against known results - One test is commented out corresponding to an edge case that reveals the current code is wrong. Will enable this test after checking how many experiments are impacted but the associated bug fix. --- src/ALE/MOM_remapping.F90 | 264 ++++++++++++++++++++++++++------------ 1 file changed, 180 insertions(+), 84 deletions(-) diff --git a/src/ALE/MOM_remapping.F90 b/src/ALE/MOM_remapping.F90 index 09ef896014..ff50b54f24 100644 --- a/src/ALE/MOM_remapping.F90 +++ b/src/ALE/MOM_remapping.F90 @@ -493,8 +493,6 @@ subroutine remap_via_sub_cells( n0, h0, u0, ppoly0_E, ppoly0_coefs, n1, h1, meth integer :: i_sub !

However, this is only a valid assumption (and correct) if the total column thickness of source/target are the same. That is generally true doing the main loop. However, when initializing from WOA, the ocean model depth and source-data depth often differ, and this assumption that we can ignore the top/bottom reconstructions breaks. - The original fix was developed with @claireyung and took the form https://github.com/claireyung/MOM6/commit/924b7ac9cd27179327f536b1cabc5582ad717b92 In this patch, I have unrolled the loop inside remap_src_to_sub_grid() to avoid adding an additional `if` test on the loop index. - The fix is implemented in remap_src_to_sub_grid() and the original method is reached by setting a logical inside the remapping_CS. Default is to use the OM4 alorithm (original method with bug). - New runtime parameters are added in to recover original algorithm selectively: - OBC_REMAPPING_USE_OM4_SUBCELLS, - Z_INIT_REMAPPING_USE_OM4_SUBCELLS, - EBT_REMAPPING_USE_OM4_SUBCELLS, - SPONGE_REMAPPING_USE_OM4_SUBCELLS, - SPONGE_REMAPPING_USE_OM4_SUBCELLS, - DIAG_REMAPPING_USE_OM4_SUBCELLS, - NDIFF_REMAPPING_USE_OM4_SUBCELLS, - HBD_REMAPPING_USE_OM4_SUBCELLS, - INTWAVE_REMAPPING_USE_OM4_SUBCELLS, and - REMAPPING_USE_OM4_SUBCELLS all of which default to True. - No answer changes. --- src/ALE/MOM_ALE.F90 | 23 + src/ALE/MOM_remapping.F90 | 498 +++++++++++++++--- src/core/MOM_open_boundary.F90 | 6 + src/diagnostics/MOM_diagnostics.F90 | 7 +- src/diagnostics/MOM_wave_speed.F90 | 6 +- src/framework/MOM_diag_mediator.F90 | 7 +- src/framework/MOM_diag_remap.F90 | 6 +- .../MOM_state_initialization.F90 | 8 +- .../MOM_tracer_initialization_from_Z.F90 | 8 +- src/ocean_data_assim/MOM_oda_driver.F90 | 5 +- src/ocean_data_assim/MOM_oda_incupd.F90 | 6 +- .../lateral/MOM_internal_tides.F90 | 8 +- .../lateral/MOM_lateral_mixing_coeffs.F90 | 7 +- .../vertical/MOM_ALE_sponge.F90 | 12 + src/tracer/MOM_hor_bnd_diffusion.F90 | 16 +- src/tracer/MOM_neutral_diffusion.F90 | 6 + 16 files changed, 536 insertions(+), 93 deletions(-) diff --git a/src/ALE/MOM_ALE.F90 b/src/ALE/MOM_ALE.F90 index a083402fde..0ae5fb1e92 100644 --- a/src/ALE/MOM_ALE.F90 +++ b/src/ALE/MOM_ALE.F90 @@ -178,6 +178,7 @@ subroutine ALE_init( param_file, GV, US, max_depth, CS) logical :: local_logical logical :: remap_boundary_extrap logical :: init_boundary_extrap + logical :: om4_remap_via_sub_cells type(hybgen_regrid_CS), pointer :: hybgen_regridCS => NULL() !

It was found that the allocations were unnecessary, and the fields were redefined as local variables within functions, without the initialization to zero. Although the uninitialized points were masked and unused in the rest of the model, they were still able to change the checksums and were being reported as regressions. This patch restores the original checksums by re-implementing the zero initialization.

This parameter replicates the previous method, which keeps `stencil` at 2 when PPM:H3 is used. ---- The logical parameters are * P = CS%usePPM * H = CS%useHuynh * E = USE_HUYNH_STENCIL_BUG * R = CS%useHuynhStencilBug The three expressions of interest: 1. P & ~H 2. P 3. P & ~R (1) is the original incorrect expression, (2) is the fixed expression, and (3) is the proposed update. What we want: If E is false, then (3) should reduce to (2). If E is true, then (3) should reduce to (1). R is computed as follows: * R = False (from derived type initialization) * if (H) R = E (from get_param call) This is equivalent to R = H & E, and (3) is P & ~(H & E). * If E is False, then P & ~(H & False) = P. * If E is True, then P & ~(H & True) = P & ~H So this flag should replicate both the previous and current behavior. --- src/tracer/MOM_tracer_advect.F90 | 19 ++++++++++++++++--- 1 file changed, 16 insertions(+), 3 deletions(-) diff --git a/src/tracer/MOM_tracer_advect.F90 b/src/tracer/MOM_tracer_advect.F90 index b77949342d..e927f2f89d 100644 --- a/src/tracer/MOM_tracer_advect.F90 +++ b/src/tracer/MOM_tracer_advect.F90 @@ -34,6 +34,8 @@ module MOM_tracer_advect logical :: debug !< If true, write verbose checksums for debugging purposes. logical :: usePPM !< If true, use PPM instead of PLM logical :: useHuynh !< If true, use the Huynh scheme for PPM interface values + logical :: useHuynhStencilBug = .false. !< If true, use the incorrect stencil width. + !!

This requires a revision to the order of arguments to MOM_generic_tracer_min_max. The interface to array_global_min_max was extensively revised and simplified to replace several previous arguments with a single new ocean_grid_type argument, to make the location arguments optional, and add an optional unscale argument. This commit fixes a number of problems that had previously been noted with array_global_min_max, including that: (1) It actually returns the global minimum and maximum values of the tracer; (2) It gives a position that is independent of the domain decomposition and grid rotation; (3) For all-zero arrays it correctly reports 0 for the minimum and maximum; (4) It properly handles unscaling of the input array; (5) It does not use a 3-d mask array that is actually just a 2-d mask array; (6) It is more efficient by grouping the global minimum and maximum calls. This commit also adds or revises comments to document the units and purpose of the remaining undocumented real variables in MOM_generic_tracer.F90. These changes were tested and verified to be correct by calling array_global_min_max for temperatures and salinities from write_energy, but those changes were not included in this commit. This commit also adds an optional verbosity argument to g_tracer_flux_init in config_src/external/GFDL_ocean_BGC/generic_tracer_utils.F90, reflecting a change to ocean_BGC/generic_tracers/generic_tracer_utils.F90 that was adopted in August of 2020, and is uses this new verbosity argument in the call from MOM_generic_flux_init. While all solutions are bitwise identical, there are changes (corrections) in some diagnostic output, and there are changes to the arguments of publicly visible routines. --- .../GFDL_ocean_BGC/generic_tracer_utils.F90 | 3 +- src/tracer/MOM_generic_tracer.F90 | 364 +++++++++++------- src/tracer/MOM_tracer_flow_control.F90 | 7 +- 3 files changed, 223 insertions(+), 151 deletions(-) diff --git a/config_src/external/GFDL_ocean_BGC/generic_tracer_utils.F90 b/config_src/external/GFDL_ocean_BGC/generic_tracer_utils.F90 index fec9c80461..5c87c37e70 100644 --- a/config_src/external/GFDL_ocean_BGC/generic_tracer_utils.F90 +++ b/config_src/external/GFDL_ocean_BGC/generic_tracer_utils.F90 @@ -99,8 +99,9 @@ module g_tracer_utils contains !> Unknown - subroutine g_tracer_flux_init(g_tracer) + subroutine g_tracer_flux_init(g_tracer, verbosity) type(g_tracer_type), pointer :: g_tracer !< Pointer to this tracer node + integer, optional, intent(in) :: verbosity !< A 0-9 integer indicating a level of verbosity end subroutine g_tracer_flux_init !> Unknown diff --git a/src/tracer/MOM_generic_tracer.F90 b/src/tracer/MOM_generic_tracer.F90 index f430e94515..6168ec1d70 100644 --- a/src/tracer/MOM_generic_tracer.F90 +++ b/src/tracer/MOM_generic_tracer.F90 @@ -67,7 +67,7 @@ module MOM_generic_tracer public end_MOM_generic_tracer, MOM_generic_tracer_get public MOM_generic_tracer_stock public MOM_generic_flux_init - public MOM_generic_tracer_min_max + public MOM_generic_tracer_min_max, array_global_min_max public MOM_generic_tracer_fluxes_accumulate public register_MOM_generic_tracer_segments @@ -206,7 +206,7 @@ function register_MOM_generic_tracer(HI, GV, param_file, CS, tr_Reg, restart_CS) !!nnz: MOM field is 3D.

This is only a concern when using certain GPU-related flags in the Nvidia compiler, and is only a problem for libraries with a significant amount of C code, such as FMS. --- .testing/Makefile | 2 +- ac/configure.ac | 4 ++-- ac/deps/configure.fms.ac | 16 ++++++++++++++-- 3 files changed, 17 insertions(+), 5 deletions(-) diff --git a/.testing/Makefile b/.testing/Makefile index 83dd7dc478..085fea2655 100644 --- a/.testing/Makefile +++ b/.testing/Makefile @@ -651,7 +651,7 @@ $(WORK)/%/restart/ocean.stats: $(BUILD)/symmetric/MOM6 | preproc # Not a true rule; only call this after `make test` to summarize test results. .PHONY: test.summary test.summary: - @./tools/report_test_results.sh $(WORK)/results + ./tools/report_test_results.sh $(WORK)/results #--- diff --git a/ac/configure.ac b/ac/configure.ac index 8196e2eb01..071f43f5a9 100644 --- a/ac/configure.ac +++ b/ac/configure.ac @@ -81,8 +81,8 @@ AS_IF([test "x$with_driver" != "x"], # Explicitly assume free-form Fortran -AC_LANG(Fortran) -AC_FC_SRCEXT(f90) +AC_LANG([Fortran]) +AC_FC_SRCEXT([f90]) # Determine MPI compiler wrappers diff --git a/ac/deps/configure.fms.ac b/ac/deps/configure.fms.ac index a52533970b..7d68daa3c7 100644 --- a/ac/deps/configure.fms.ac +++ b/ac/deps/configure.fms.ac @@ -10,7 +10,16 @@ AC_INIT( AC_CONFIG_SRCDIR([fms/fms.F90]) AC_CONFIG_MACRO_DIR([m4]) + # C configuration + +# Autoconf assumes that LDFLAGS can be passed to CFLAGS, even though this is +# not valid in some compilers.

This included changes to 6 calls to myStats in the two horiz_interp_and_extrap_tracer routines. Although myStats is public, it really is only used in MOM_horizontal_regridding in the main version of MOM6, apart from a single call in MOM_initialize_tracer_from_Z that does not use the optional unscale argument, so rather than adding a second optional argument, this case seemed to be safe enough to rename the argument in place. If there were any unanticipated problems with this argument name change, they would be manifest in code that does not compile.

These are synonymous with the existing optional scale arguments to these routines, and if both are provided, the new unscale arguments take precedence. All this is done to come up with a more systematic nomenclature for the various scaling and unscaling arguments, so that the factors passed to them will follow a more regular pattern. With this change, the `scale=` argument to a get_param or read_data call will take the opposite setting to the `unscale=` argument used in a checksum call. For example, for a velocity, these arguments would be `scale=US%m_s_to_L_T` and `unscale=US%L_T_to_m_s`, but the reverse values of `scale=US%L_T_to_m_s` and `unscale=US%m_s_to_L_T` would only work for inverse velocities and will therefore be very uncommon and warrant extra scrutiny. With this change, `unscale=` and `conversion=` arguments used when registering diagnostics will often take similar arguments, although the latter can also have extra factors that are unrelated to dimensional rescaling. As a test of these capabilities, these new `unscale` arguments are being used in 23 calls from the MOM_chksum_packages routines and in 76 calls to chksums or global integrals from MOM_forcing_chksum(), MOM_mech_forcing_chksum() and forcing_diagnostics(). The results are equivalent to what was generated before in cases with debugging enabled so the revised code would be exercised. All answers are bitwise identical, but there are new optional arguments to 25 publicly visible routines. --- src/core/MOM_checksum_packages.F90 | 46 ++-- src/core/MOM_forcing_type.F90 | 152 ++++++------- src/diagnostics/MOM_spatial_means.F90 | 121 +++++++--- src/framework/MOM_checksums.F90 | 311 +++++++++++++++++--------- 4 files changed, 398 insertions(+), 232 deletions(-) diff --git a/src/core/MOM_checksum_packages.F90 b/src/core/MOM_checksum_packages.F90 index dc60e0888f..2eb84a1c74 100644 --- a/src/core/MOM_checksum_packages.F90 +++ b/src/core/MOM_checksum_packages.F90 @@ -75,10 +75,10 @@ subroutine MOM_state_chksum_5arg(mesg, u, v, h, uh, vh, G, GV, US, haloshift, sy scale_vel = US%L_T_to_m_s ; if (present(vel_scale)) scale_vel = vel_scale call uvchksum(mesg//" [uv]", u, v, G%HI, haloshift=hs, symmetric=sym, & - omit_corners=omit_corners, scale=scale_vel) - call hchksum(h, mesg//" h", G%HI, haloshift=hs, omit_corners=omit_corners, scale=GV%H_to_MKS) + omit_corners=omit_corners, unscale=scale_vel) + call hchksum(h, mesg//" h", G%HI, haloshift=hs, omit_corners=omit_corners, unscale=GV%H_to_MKS) call uvchksum(mesg//" [uv]h", uh, vh, G%HI, haloshift=hs, symmetric=sym, & - omit_corners=omit_corners, scale=GV%H_to_MKS*US%L_to_m**2*US%s_to_T) + omit_corners=omit_corners, unscale=GV%H_to_MKS*US%L_to_m**2*US%s_to_T) end subroutine MOM_state_chksum_5arg !

These new unscale arguments are synonymous with the existing optional scale arguments to these routines, and if both are provided, the new unscale arguments take precedence. A total of 26 MOM_write_field calls in save_restart, write_depth_list, write_Hybgen_coord_file, write_vertgrid_file and write_ocean_geometry_file were modified to replace a scale argument with the new unscale argument. All answers are bitwise identical, but there are new optional arguments to 10 publicly visible routines. --- src/ALE/MOM_hybgen_regrid.F90 | 6 +- src/diagnostics/MOM_sum_output.F90 | 6 +- src/framework/MOM_io.F90 | 181 +++++++++++++----- src/framework/MOM_restart.F90 | 10 +- .../MOM_coord_initialization.F90 | 4 +- .../MOM_shared_initialization.F90 | 42 ++-- .../vertical/MOM_bkgnd_mixing.F90 | 8 +- 7 files changed, 168 insertions(+), 89 deletions(-) diff --git a/src/ALE/MOM_hybgen_regrid.F90 b/src/ALE/MOM_hybgen_regrid.F90 index 491693549f..8c0733be78 100644 --- a/src/ALE/MOM_hybgen_regrid.F90 +++ b/src/ALE/MOM_hybgen_regrid.F90 @@ -258,9 +258,9 @@ subroutine write_Hybgen_coord_file(GV, CS, filepath) call create_MOM_file(IO_handle, trim(filepath), vars, 3, fields, & SINGLE_FILE, GV=GV) - call MOM_write_field(IO_handle, fields(1), CS%dp0k, scale=CS%coord_scale) - call MOM_write_field(IO_handle, fields(2), CS%ds0k, scale=CS%coord_scale) - call MOM_write_field(IO_handle, fields(3), CS%target_density, scale=CS%Rho_coord_scale) + call MOM_write_field(IO_handle, fields(1), CS%dp0k, unscale=CS%coord_scale) + call MOM_write_field(IO_handle, fields(2), CS%ds0k, unscale=CS%coord_scale) + call MOM_write_field(IO_handle, fields(3), CS%target_density, unscale=CS%Rho_coord_scale) call IO_handle%close() end subroutine write_Hybgen_coord_file diff --git a/src/diagnostics/MOM_sum_output.F90 b/src/diagnostics/MOM_sum_output.F90 index fb95b79a91..edb66d225c 100644 --- a/src/diagnostics/MOM_sum_output.F90 +++ b/src/diagnostics/MOM_sum_output.F90 @@ -1269,9 +1269,9 @@ subroutine write_depth_list(G, US, DL, filename) call create_MOM_file(IO_handle, filename, vars, 3, fields, SINGLE_FILE, & extra_axes=extra_axes, global_atts=global_atts) - call MOM_write_field(IO_handle, fields(1), DL%depth, scale=US%Z_to_m) - call MOM_write_field(IO_handle, fields(2), DL%area, scale=US%L_to_m**2) - call MOM_write_field(IO_handle, fields(3), DL%vol_below, scale=US%Z_to_m*US%L_to_m**2) + call MOM_write_field(IO_handle, fields(1), DL%depth, unscale=US%Z_to_m) + call MOM_write_field(IO_handle, fields(2), DL%area, unscale=US%L_to_m**2) + call MOM_write_field(IO_handle, fields(3), DL%vol_below, unscale=US%Z_to_m*US%L_to_m**2) call delete_axis_info(extra_axes) call delete_attribute_info(global_atts) diff --git a/src/framework/MOM_io.F90 b/src/framework/MOM_io.F90 index 27d244b226..8ee192323a 100644 --- a/src/framework/MOM_io.F90 +++ b/src/framework/MOM_io.F90 @@ -2504,7 +2504,7 @@ end subroutine MOM_read_vector_3d !> Write a 4d field to an output file, potentially with rotation subroutine MOM_write_field_legacy_4d(IO_handle, field_md, MOM_domain, field, tstamp, tile_count, & - fill_value, turns, scale) + fill_value, turns, scale, unscale) type(file_type), intent(inout) :: IO_handle !< Handle for a file that is open for writing type(fieldtype), intent(in) :: field_md !< Field type with metadata type(MOM_domain_type), intent(in) :: MOM_domain !< The MOM_Domain that describes the decomposition @@ -2516,7 +2516,13 @@ subroutine MOM_write_field_legacy_4d(IO_handle, field_md, MOM_domain, field, tst real, optional, intent(in) :: scale !< A scaling factor that the field is multiplied by before !! it is written [a A-1 ~> 1], for example to convert it !! from its internal units to the desired units for output + real, optional, intent(in) :: unscale !< A scaling factor that the field is multiplied by before + !! it is written [a A-1 ~> 1], for example to convert it + !! from its internal units to the desired units for output. + !!

This new routine is used to allow for the redundant value checks in various step_MOM routines to be enabled or disabled at run-time when debugging is on overall (by setting DEBUG = True). For cases with inconsistent redundant points, this change allows for a reduction in the volume of debugging information sent to stdout from multiple PEs (in an arbitrary order), while for cases without inconsistent redundant points this change will allow for faster debugging with checksums alone. All answers are bitwise identical, but there is a new publicly visible routine. --- src/core/MOM.F90 | 24 ++++++++++----- src/core/MOM_dynamics_split_RK2.F90 | 44 ++++++++++++++++++---------- src/core/MOM_dynamics_split_RK2b.F90 | 44 ++++++++++++++++++---------- src/diagnostics/MOM_debugging.F90 | 13 ++++++++ 4 files changed, 86 insertions(+), 39 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 8f0f0e7462..8b34b3e6a3 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -6,7 +6,7 @@ module MOM !

To do this, it adds and calls the new routine set_params_buggy_Wright() when appropriate, and adds the new element "three" to the buggy_Wright_EOS type. When the bug is fixed, buggy_Wright_EOS%three = 3, but ...%three = 2 to recreate the bug. This commit does change answers for cases using the "WRIGHT" equation of state and one of the "USE_STANLEY_..." parameterizations from those on the dev/gfdl branch of MOM6, but in so doing it restores the answers on the main branch of MOM6. There is also a new publicly visible subroutine. --- src/equation_of_state/MOM_EOS.F90 | 3 +++ src/equation_of_state/MOM_EOS_Wright.F90 | 31 +++++++++++++++++++++--- 2 files changed, 31 insertions(+), 3 deletions(-) diff --git a/src/equation_of_state/MOM_EOS.F90 b/src/equation_of_state/MOM_EOS.F90 index 7a9de49573..1567d20692 100644 --- a/src/equation_of_state/MOM_EOS.F90 +++ b/src/equation_of_state/MOM_EOS.F90 @@ -1526,6 +1526,7 @@ subroutine EOS_init(param_file, EOS, US) "If true, use a bug in the calculation of the second derivatives of density "//& "with temperature and with temperature and pressure that causes some terms "//& "to be only 2/3 of what they should be.", default=.false.) + call EOS_manual_init(EOS, form_of_EOS=EOS_WRIGHT, use_Wright_2nd_deriv_bug=EOS%use_Wright_2nd_deriv_bug) endif EOS_quad_default = .not.((EOS%form_of_EOS == EOS_LINEAR) .or. & @@ -1645,6 +1646,8 @@ subroutine EOS_manual_init(EOS, form_of_EOS, form_of_TFreeze, EOS_quadrature, Co select type (t => EOS%type) type is (linear_EOS) call t%set_params_linear(Rho_T0_S0, dRho_dT, dRho_dS) + type is (buggy_Wright_EOS) + call t%set_params_buggy_Wright(use_Wright_2nd_deriv_bug) end select endif if (present(form_of_TFreeze)) EOS%form_of_TFreeze = form_of_TFreeze diff --git a/src/equation_of_state/MOM_EOS_Wright.F90 b/src/equation_of_state/MOM_EOS_Wright.F90 index 8b6d6495d1..d4b091b7b2 100644 --- a/src/equation_of_state/MOM_EOS_Wright.F90 +++ b/src/equation_of_state/MOM_EOS_Wright.F90 @@ -12,6 +12,7 @@ module MOM_EOS_Wright public buggy_Wright_EOS public int_density_dz_wright, int_spec_vol_dp_wright public avg_spec_vol_buggy_Wright +public set_params_buggy_Wright !>@{ Parameters in the Wright equation of state using the reduced range formula, which is a fit to the UNESCO ! equation of state for the restricted range: -2 < theta < 30 [degC], 28 < S < 38 [PSU], 0 < p < 5e7 [Pa]. @@ -39,6 +40,8 @@ module MOM_EOS_Wright !> The EOS_base implementation of the Wright 1997 equation of state with some bugs type, extends (EOS_base) :: buggy_Wright_EOS + real :: three = 3.0 !< A constant that can be adjusted to recreate some bugs [nondim] + contains !> Implementation of the in-situ density as an elemental function [kg m-3] procedure :: density_elem => density_elem_buggy_Wright @@ -59,6 +62,9 @@ module MOM_EOS_Wright !> Implementation of the range query function procedure :: EOS_fit_range => EOS_fit_range_buggy_Wright + !> Instance specific function to set internal parameters + procedure :: set_params_buggy_Wright => set_params_buggy_Wright + !> Local implementation of generic calculate_density_array for efficiency procedure :: calculate_density_array => calculate_density_array_buggy_Wright !> Local implementation of generic calculate_spec_vol_array for efficiency @@ -228,13 +234,16 @@ elemental subroutine calculate_density_second_derivs_elem_buggy_Wright(this, T, real :: z11 !

The (incorrect) non-Boussinesq version of the test for where interfaces are outside of the range of hydrostatic consistency due to interactions with bathymetry was converted from the (correct) Boussinesq version without properly taking into account that pressure increases downward while height increases upward. This bug is repeated 12 times in 6 different specific volume integral routines, including in the analytical specific volume integrals with 4 equations of state. To accommodate these corrections as well as a future expansion of the mass weighting to apply near the surface under ice-shelves or icebergs, the previous optional logical argument (useMassWghtInterp) was replaced with a new optional integer argument (MassWghtInterp) that can be used to encode information about where this weighting is applied as well as whether to fix this bug. This combination of settings (MASS_WEIGHT_IN_PRESSURE_GRADIENT = True and non-Boussinesq) does not seem to be widely used yet (it is not used in the GFDL regression suite), so rather than preserving the old (incorrect) solutions by default, this bug is corrected by default. However, the previous answers can be recovered by setting the new runtime parameter MASS_WEIGHT_IN_PGF_NONBOUS_BUG to true. This parameter that is only used (and logged) for non-Boussinesq cases with MASS_WEIGHT_IN_PRESSURE_GRADIENT set to true. It is intended that this new runtime bug-fix parameter will be obsoleted with an aggressive schedule if it is not needed to recreate any production runs. In addition, there are two new diagnostics, MassWt_u and MassWt_v, that show the fractional (0 to 1) effects of the mass weighting in the pressure gradient forces at the velocity points, along with the new diagnostic subroutines diagnose_mass_weight_Z and diagnose_mass_weight_p that calculate these diagnostics by layer in code that replicates the 13 copies for various equations of state and vertical structures within layers. By default, this commit does change answers in non-Boussinesq cases that use MASS_WEIGHT_IN_PRESSURE_GRADIENT = True, and there is a new runtime parameter in such cases. There are also two new diagnostics. Answers are bitwise identical in all Boussinesq cases. --- src/core/MOM_PressureForce_FV.F90 | 60 ++++- src/core/MOM_density_integrals.F90 | 244 ++++++++++++++---- src/equation_of_state/MOM_EOS.F90 | 36 +-- src/equation_of_state/MOM_EOS_Wright.F90 | 50 ++-- src/equation_of_state/MOM_EOS_Wright_full.F90 | 50 ++-- src/equation_of_state/MOM_EOS_Wright_red.F90 | 50 ++-- src/equation_of_state/MOM_EOS_linear.F90 | 50 ++-- 7 files changed, 378 insertions(+), 162 deletions(-) diff --git a/src/core/MOM_PressureForce_FV.F90 b/src/core/MOM_PressureForce_FV.F90 index 5d0f4ff167..9c4f355692 100644 --- a/src/core/MOM_PressureForce_FV.F90 +++ b/src/core/MOM_PressureForce_FV.F90 @@ -20,6 +20,7 @@ module MOM_PressureForce_FV use MOM_density_integrals, only : int_density_dz_generic_plm, int_density_dz_generic_ppm use MOM_density_integrals, only : int_spec_vol_dp_generic_plm use MOM_density_integrals, only : int_density_dz_generic_pcm, int_spec_vol_dp_generic_pcm +use MOM_density_integrals, only : diagnose_mass_weight_Z, diagnose_mass_weight_p use MOM_ALE, only : TS_PLM_edge_values, TS_PPM_edge_values, ALE_CS implicit none ; private @@ -46,7 +47,7 @@ module MOM_PressureForce_FV type(time_type), pointer :: Time !< A pointer to the ocean model's clock. type(diag_ctrl), pointer :: diag !< A structure that is used to regulate the !! timing of diagnostic output. - logical :: useMassWghtInterp !< Use mass weighting in T/S interpolation + integer :: MassWghtInterp !< A flag indicating whether and how to use mass weighting in T/S interpolation logical :: use_inaccurate_pgf_rho_anom !< If true, uses the older and less accurate !! method to calculate density anomalies, as used prior to !!

This change enforces the order of arithmetic that is required to give rotational symmetry, but it also is the order that the Intel, GNU, and Nvidia compliers were all already using in these expressions. Moreover, had the order of arithmetic ever been anything else, this would have led to failures in our rotational consistency and redundant point consistency testing, and almost certainly would have been detected before. However, by adding these parentheses, there is a remote chance that the addition of these parentheses could change answers for some compiler or compiler settings we have never tested before. This change should not impact any FMA-enabled calculations. All answers are bitwise identical in the MOM6-examples regression suite as run on Gaea. --- src/core/MOM_continuity_PPM.F90 | 18 +++++++++--------- 1 file changed, 9 insertions(+), 9 deletions(-) diff --git a/src/core/MOM_continuity_PPM.F90 b/src/core/MOM_continuity_PPM.F90 index ba8c234bc2..13181902ec 100644 --- a/src/core/MOM_continuity_PPM.F90 +++ b/src/core/MOM_continuity_PPM.F90 @@ -937,14 +937,14 @@ subroutine zonal_flux_layer(u, h, h_W, h_E, uh, duhdu, visc_rem, dt, G, US, j, & if (u(I) > 0.0) then if (vol_CFL) then ; CFL = (u(I) * dt) * (G%dy_Cu(I,j) * G%IareaT(i,j)) else ; CFL = u(I) * dt * G%IdxT(i,j) ; endif - curv_3 = h_W(i) + h_E(i) - 2.0*h(i) + curv_3 = (h_W(i) + h_E(i)) - 2.0*h(i) uh(I) = (G%dy_Cu(I,j) * por_face_areaU(I)) * u(I) * & (h_E(i) + CFL * (0.5*(h_W(i) - h_E(i)) + curv_3*(CFL - 1.5))) h_marg = h_E(i) + CFL * ((h_W(i) - h_E(i)) + 3.0*curv_3*(CFL - 1.0)) elseif (u(I) < 0.0) then if (vol_CFL) then ; CFL = (-u(I) * dt) * (G%dy_Cu(I,j) * G%IareaT(i+1,j)) else ; CFL = -u(I) * dt * G%IdxT(i+1,j) ; endif - curv_3 = h_W(i+1) + h_E(i+1) - 2.0*h(i+1) + curv_3 = (h_W(i+1) + h_E(i+1)) - 2.0*h(i+1) uh(I) = (G%dy_Cu(I,j) * por_face_areaU(I)) * u(I) * & (h_W(i+1) + CFL * (0.5*(h_E(i+1)-h_W(i+1)) + curv_3*(CFL - 1.5))) h_marg = h_W(i+1) + CFL * ((h_E(i+1)-h_W(i+1)) + 3.0*curv_3*(CFL - 1.0)) @@ -1019,13 +1019,13 @@ subroutine zonal_flux_thickness(u, h, h_W, h_E, h_u, dt, G, GV, US, LB, vol_CFL, if (u(I,j,k) > 0.0) then if (vol_CFL) then ; CFL = (u(I,j,k) * dt) * (G%dy_Cu(I,j) * G%IareaT(i,j)) else ; CFL = u(I,j,k) * dt * G%IdxT(i,j) ; endif - curv_3 = h_W(i,j,k) + h_E(i,j,k) - 2.0*h(i,j,k) + curv_3 = (h_W(i,j,k) + h_E(i,j,k)) - 2.0*h(i,j,k) h_avg = h_E(i,j,k) + CFL * (0.5*(h_W(i,j,k) - h_E(i,j,k)) + curv_3*(CFL - 1.5)) h_marg = h_E(i,j,k) + CFL * ((h_W(i,j,k) - h_E(i,j,k)) + 3.0*curv_3*(CFL - 1.0)) elseif (u(I,j,k) < 0.0) then if (vol_CFL) then ; CFL = (-u(I,j,k)*dt) * (G%dy_Cu(I,j) * G%IareaT(i+1,j)) else ; CFL = -u(I,j,k) * dt * G%IdxT(i+1,j) ; endif - curv_3 = h_W(i+1,j,k) + h_E(i+1,j,k) - 2.0*h(i+1,j,k) + curv_3 = (h_W(i+1,j,k) + h_E(i+1,j,k)) - 2.0*h(i+1,j,k) h_avg = h_W(i+1,j,k) + CFL * (0.5*(h_E(i+1,j,k)-h_W(i+1,j,k)) + curv_3*(CFL - 1.5)) h_marg = h_W(i+1,j,k) + CFL * ((h_E(i+1,j,k)-h_W(i+1,j,k)) + & 3.0*curv_3*(CFL - 1.0)) @@ -1832,7 +1832,7 @@ subroutine merid_flux_layer(v, h, h_S, h_N, vh, dvhdv, visc_rem, dt, G, US, J, & if (v(i) > 0.0) then if (vol_CFL) then ; CFL = (v(i) * dt) * (G%dx_Cv(i,J) * G%IareaT(i,j)) else ; CFL = v(i) * dt * G%IdyT(i,j) ; endif - curv_3 = h_S(i,j) + h_N(i,j) - 2.0*h(i,j) + curv_3 = (h_S(i,j) + h_N(i,j)) - 2.0*h(i,j) vh(i) = (G%dx_Cv(i,J)*por_face_areaV(i,J)) * v(i) * ( h_N(i,j) + CFL * & (0.5*(h_S(i,j) - h_N(i,j)) + curv_3*(CFL - 1.5)) ) h_marg = h_N(i,j) + CFL * ((h_S(i,j) - h_N(i,j)) + & @@ -1840,7 +1840,7 @@ subroutine merid_flux_layer(v, h, h_S, h_N, vh, dvhdv, visc_rem, dt, G, US, J, & elseif (v(i) < 0.0) then if (vol_CFL) then ; CFL = (-v(i) * dt) * (G%dx_Cv(i,J) * G%IareaT(i,j+1)) else ; CFL = -v(i) * dt * G%IdyT(i,j+1) ; endif - curv_3 = h_S(i,j+1) + h_N(i,j+1) - 2.0*h(i,j+1) + curv_3 = (h_S(i,j+1) + h_N(i,j+1)) - 2.0*h(i,j+1) vh(i) = (G%dx_Cv(i,J)*por_face_areaV(i,J)) * v(i) * ( h_S(i,j+1) + CFL * & (0.5*(h_N(i,j+1)-h_S(i,j+1)) + curv_3*(CFL - 1.5)) ) h_marg = h_S(i,j+1) + CFL * ((h_N(i,j+1)-h_S(i,j+1)) + & @@ -1919,14 +1919,14 @@ subroutine meridional_flux_thickness(v, h, h_S, h_N, h_v, dt, G, GV, US, LB, vol if (v(i,J,k) > 0.0) then if (vol_CFL) then ; CFL = (v(i,J,k) * dt) * (G%dx_Cv(i,J) * G%IareaT(i,j)) else ; CFL = v(i,J,k) * dt * G%IdyT(i,j) ; endif - curv_3 = h_S(i,j,k) + h_N(i,j,k) - 2.0*h(i,j,k) + curv_3 = (h_S(i,j,k) + h_N(i,j,k)) - 2.0*h(i,j,k) h_avg = h_N(i,j,k) + CFL * (0.5*(h_S(i,j,k) - h_N(i,j,k)) + curv_3*(CFL - 1.5)) h_marg = h_N(i,j,k) + CFL * ((h_S(i,j,k) - h_N(i,j,k)) + & 3.0*curv_3*(CFL - 1.0)) elseif (v(i,J,k) < 0.0) then if (vol_CFL) then ; CFL = (-v(i,J,k)*dt) * (G%dx_Cv(i,J) * G%IareaT(i,j+1)) else ; CFL = -v(i,J,k) * dt * G%IdyT(i,j+1) ; endif - curv_3 = h_S(i,j+1,k) + h_N(i,j+1,k) - 2.0*h(i,j+1,k) + curv_3 = (h_S(i,j+1,k) + h_N(i,j+1,k)) - 2.0*h(i,j+1,k) h_avg = h_S(i,j+1,k) + CFL * (0.5*(h_N(i,j+1,k)-h_S(i,j+1,k)) + curv_3*(CFL - 1.5)) h_marg = h_S(i,j+1,k) + CFL * ((h_N(i,j+1,k)-h_S(i,j+1,k)) + & 3.0*curv_3*(CFL - 1.0)) @@ -2601,7 +2601,7 @@ subroutine PPM_limit_pos(h_in, h_L, h_R, h_min, G, iis, iie, jis, jie) do j=jis,jie ; do i=iis,iie !

This commit does add a new element to two transparent types. --- src/core/MOM_barotropic.F90 | 8 +++---- src/core/MOM_grid.F90 | 8 ++++--- src/core/MOM_transcribe_grid.F90 | 4 ++++ src/diagnostics/MOM_diagnostics.F90 | 8 +++---- src/framework/MOM_dyn_horgrid.F90 | 9 +++++--- .../MOM_fixed_initialization.F90 | 13 ++++++++--- .../lateral/MOM_internal_tides.F90 | 22 +++++++++---------- .../lateral/MOM_lateral_mixing_coeffs.F90 | 10 ++++----- .../vertical/MOM_kappa_shear.F90 | 6 ++--- .../vertical/MOM_set_diffusivity.F90 | 4 ++-- 10 files changed, 54 insertions(+), 38 deletions(-) diff --git a/src/core/MOM_barotropic.F90 b/src/core/MOM_barotropic.F90 index 83bfab0820..f3d01bd886 100644 --- a/src/core/MOM_barotropic.F90 +++ b/src/core/MOM_barotropic.F90 @@ -1649,8 +1649,8 @@ subroutine btstep(U_in, V_in, eta_in, dt, bc_accel_u, bc_accel_v, forces, pbce, gtot_W(i,j) * (Datu(I-1,j)*G%IdxCu(I-1,j))) + & (gtot_N(i,j) * (Datv(i,J)*G%IdyCv(i,J)) + & gtot_S(i,j) * (Datv(i,J-1)*G%IdyCv(i,J-1)))) + & - ((G%CoriolisBu(I,J)**2 + G%CoriolisBu(I-1,J-1)**2) + & - (G%CoriolisBu(I-1,J)**2 + G%CoriolisBu(I,J-1)**2)) * CS%BT_Coriolis_scale**2 ) + ((G%Coriolis2Bu(I,J) + G%Coriolis2Bu(I-1,J-1)) + & + (G%Coriolis2Bu(I-1,J) + G%Coriolis2Bu(I,J-1))) * CS%BT_Coriolis_scale**2 ) H_eff_dx2 = max(H_min_dyn * ((G%IdxT(i,j))**2 + (G%IdyT(i,j))**2), & G%IareaT(i,j) * & ((Datu(I,j)*G%IdxCu(I,j) + Datu(I-1,j)*G%IdxCu(I-1,j)) + & @@ -2906,8 +2906,8 @@ subroutine set_dtbt(G, GV, US, CS, eta, pbce, BT_cont, gtot_est, SSH_add) Idt_max2 = 0.5 * (1.0 + 2.0*CS%bebt) * (G%IareaT(i,j) * & ((gtot_E(i,j)*Datu(I,j)*G%IdxCu(I,j) + gtot_W(i,j)*Datu(I-1,j)*G%IdxCu(I-1,j)) + & (gtot_N(i,j)*Datv(i,J)*G%IdyCv(i,J) + gtot_S(i,j)*Datv(i,J-1)*G%IdyCv(i,J-1))) + & - ((G%CoriolisBu(I,J)**2 + G%CoriolisBu(I-1,J-1)**2) + & - (G%CoriolisBu(I-1,J)**2 + G%CoriolisBu(I,J-1)**2)) * CS%BT_Coriolis_scale**2 ) + ((G%Coriolis2Bu(I,J) + G%Coriolis2Bu(I-1,J-1)) + & + (G%Coriolis2Bu(I-1,J) + G%Coriolis2Bu(I,J-1))) * CS%BT_Coriolis_scale**2 ) if (Idt_max2 * min_max_dt2 > 1.0) min_max_dt2 = 1.0 / Idt_max2 enddo ; enddo dtbt_max = sqrt(min_max_dt2 / dgeo_de) diff --git a/src/core/MOM_grid.F90 b/src/core/MOM_grid.F90 index 52e37f1a9b..6fb8426395 100644 --- a/src/core/MOM_grid.F90 +++ b/src/core/MOM_grid.F90 @@ -171,7 +171,8 @@ module MOM_grid Dblock_v, & !< Topographic depths at v-points at which the flow is blocked [Z ~> m].

One comment was also added to note that the calculation of PE_release_h is does not exhibit rotational symmetry when MEKE_GM_SRC_ALT is set to true.

FMAs can still occur, but it will be multiplication by the 0-or-1 masks that are fused with an addition. Also added parentheses to 3 expressions calculating the squared shear in calculate_projected_state for rotational symmetry with FMAs.

Also reordered terms in a sum in the calculation of beta_dx2_u to mirror that of beta_dx2_v, also for rotational symmetry with FMAs.

Also swapped the order of two terms in the expression for Del2u to mirror the order of the corresponding terms in Del2v for rotational symmetry with FMAs.

In that PR, the function remap_via_sub_cells() had been modularized into three other functions, and the near-duplicatem remap_via_sub_cells_om4(), called the two of the same functions as well as an out-of-date version of the third function. Since the reampping_core_h() function calls is already brief, calling one function in addition to remap_via_sub_cells(), and since remap_via_sub_cells() is only called from remapping_core_*(), we can remove a level of call-tree depth depth by copying remap_via_sub_grid() into reampping_core_h() and removing the unused function(s). --- src/ALE/MOM_remapping.F90 | 283 +++++++++++++++----------------------- 1 file changed, 114 insertions(+), 169 deletions(-) diff --git a/src/ALE/MOM_remapping.F90 b/src/ALE/MOM_remapping.F90 index 364a322f0f..4495e4a170 100644 --- a/src/ALE/MOM_remapping.F90 +++ b/src/ALE/MOM_remapping.F90 @@ -181,8 +181,7 @@ end subroutine extract_member_remapping_CS !! !! \todo Remove h_neglect argument by moving into remapping_CS !! \todo Remove PCM_cell argument by adding new method in Recon1D class -!! \todo Inline the two versions of remap_via_sub_cells() in remapping_core_h() to eliminate remap_via_sub_cells() -subroutine remapping_core_h(CS, n0, h0, u0, n1, h1, u1, h_neglect, h_neglect_edge, PCM_cell) +subroutine remapping_core_h(CS, n0, h0, u0, n1, h1, u1, h_neglect, h_neglect_edge, net_err, PCM_cell) type(remapping_CS), intent(in) :: CS !< Remapping control structure integer, intent(in) :: n0 !< Number of cells on source grid real, dimension(n0), intent(in) :: h0 !< Cell widths on source grid [H] @@ -196,10 +195,24 @@ subroutine remapping_core_h(CS, n0, h0, u0, n1, h1, u1, h_neglect, h_neglect_edg real, optional, intent(in) :: h_neglect_edge !< A negligibly small width !! for the purpose of edge value !! calculations in the same units as h0 [H] + real, optional, intent(out) :: net_err !< Error in total column [A H] logical, dimension(n0), optional, intent(in) :: PCM_cell !< If present, use PCM remapping for !! cells in the source grid where this is true. !

This grid was based on WOA09 but not exact because the WOA09 grid is not smooth. We tried to construct a grid such that layer centers matched the depths of WOA09 but this was not possible for six layers. As an alternative, this new coordinate, "WOA09INT", uses the WOA09 depths as interfaces so that the layer centers are always midway between the WOA09 depths. To compare with WOA09 directly, WOA data now should be interpolated but this is a simple half-half averaging. --- src/ALE/MOM_regridding.F90 | 60 +++++++++++++++++++++++++++++--------- 1 file changed, 47 insertions(+), 13 deletions(-) diff --git a/src/ALE/MOM_regridding.F90 b/src/ALE/MOM_regridding.F90 index 43d3f65a5e..7ac8cbb4a0 100644 --- a/src/ALE/MOM_regridding.F90 +++ b/src/ALE/MOM_regridding.F90 @@ -226,12 +226,22 @@ subroutine initialize_regridding(CS, GV, US, max_depth, param_file, mdl, coord_m real, dimension(:), allocatable :: dz_max !

Author: Brandon Reichl + ! Date: October 2, 2020 + ! // + ! *Note that gravity is assumed constant everywhere and divided out of all calculations. + ! + ! This code has been written to step through the columns layer by layer, summing the PE + ! change inferred by mixing the layer with all layers above. When the change exceeds a + ! threshold (determined by input array Mixing_Energy), the code needs to solve for how far + ! into this layer the threshold PE change occurs (assuming constant density layers). + ! This is expressed here via solving the function F(X) = 0 where: + ! F(X) = 0.5 * ( Ca*X^3/(D1+X) + Cb*X^2/(D1+X) + Cc*X/(D1+X) + Dc/(D1+X) + ! + Ca2*X^2 + Cb2*X + Cc2) + ! where all coefficients are determined by the previous mixed layer depth, the + ! density of the previous mixed layer, the present layer thickness, and the present + ! layer density. This equation is worked out by computing the total PE assuming constant + ! density in the mixed layer as well as in the remaining part of the present layer that is + ! not mixed. + ! To solve for X in this equation a Newton's method iteration is employed, which + ! converges extremely quickly (usually 1 guess) since this equation turns out to be rather + ! linear for PE change with increasing X. + !

Author: Brandon Reichl - ! Date: October 2, 2020 - ! // - ! *Note that gravity is assumed constant everywhere and divided out of all calculations. - ! - ! This code has been written to step through the columns layer by layer, summing the PE - ! change inferred by mixing the layer with all layers above. When the change exceeds a - ! threshold (determined by input array Mixing_Energy), the code needs to solve for how far - ! into this layer the threshold PE change occurs (assuming constant density layers). - ! This is expressed here via solving the function F(X) = 0 where: - ! F(X) = 0.5 * ( Ca*X^3/(D1+X) + Cb*X^2/(D1+X) + Cc*X/(D1+X) + Dc/(D1+X) - ! + Ca2*X^2 + Cb2*X + Cc2) - ! where all coefficients are determined by the previous mixed layer depth, the - ! density of the previous mixed layer, the present layer thickness, and the present - ! layer density. This equation is worked out by computing the total PE assuming constant - ! density in the mixed layer as well as in the remaining part of the present layer that is - ! not mixed. - ! To solve for X in this equation a Newton's method iteration is employed, which - ! converges extremely quickly (usually 1 guess) since this equation turns out to be rather - ! linear for PE change with increasing X. - !

These can be expensive global reductions, so by default these are set to false. All solutions are bitwise identical, but there can be some changes to the output to stdout and there will be new entries in the MOM_parameter_doc.debugging files. --- src/diagnostics/MOM_sum_output.F90 | 108 +++++++++++++++++++++++++---- 1 file changed, 94 insertions(+), 14 deletions(-) diff --git a/src/diagnostics/MOM_sum_output.F90 b/src/diagnostics/MOM_sum_output.F90 index edb66d225c..a97df8e94d 100644 --- a/src/diagnostics/MOM_sum_output.F90 +++ b/src/diagnostics/MOM_sum_output.F90 @@ -20,6 +20,7 @@ module MOM_sum_output use MOM_io, only : axis_info, set_axis_info, delete_axis_info, get_filename_appendix use MOM_io, only : attribute_info, set_attribute_info, delete_attribute_info use MOM_io, only : APPEND_FILE, SINGLE_FILE, WRITEONLY_FILE +use MOM_spatial_means, only : array_global_min_max use MOM_time_manager, only : time_type, get_time, get_date, set_time, operator(>) use MOM_time_manager, only : operator(+), operator(-), operator(*), operator(/) use MOM_time_manager, only : operator(/=), operator(<=), operator(>=), operator(<) @@ -124,6 +125,12 @@ module MOM_sum_output !! interval at which the run is stopped. logical :: write_stocks !< If true, write the integrated tracer amounts !! to stdout when the energy files are written. + logical :: write_min_max !< If true, write the maximum and minimum values of temperature, + !! salinity and some tracer concentrations to stdout when the energy + !! files are written. + logical :: write_min_max_loc !< If true, write the locations of the maximum and minimum values + !! of temperature, salinity and some tracer concentrations to stdout + !! when the energy files are written. integer :: previous_calls = 0 !< The number of times write_energy has been called. integer :: prev_n = 0 !< The value of n from the last call. type(MOM_netcdf_file) :: fileenergy_nc !< The file handle for the netCDF version of the energy file. @@ -179,6 +186,15 @@ subroutine MOM_sum_output_init(G, GV, US, param_file, directory, ntrnc, & call get_param(param_file, mdl, "ENABLE_THERMODYNAMICS", CS%use_temperature, & "If true, Temperature and salinity are used as state "//& "variables.", default=.true.) + call get_param(param_file, mdl, "WRITE_TRACER_MIN_MAX", CS%write_min_max, & + "If true, write the maximum and minimum values of temperature, salinity and "//& + "some tracer concentrations to stdout when the energy files are written.", & + default=.false., do_not_log=.not.CS%write_stocks, debuggingParam=.true.) + call get_param(param_file, mdl, "WRITE_TRACER_MIN_MAX_LOC", CS%write_min_max_loc, & + "If true, write the locations of the maximum and minimum values of "//& + "temperature, salinity and some tracer concentrations to stdout when the "//& + "energy files are written.", & + default=.false., do_not_log=.not.CS%write_min_max, debuggingParam=.true.) call get_param(param_file, mdl, "DT", CS%dt_in_T, & "The (baroclinic) dynamics time step.", & units="s", scale=US%s_to_T, fail_if_missing=.true.) @@ -404,6 +420,34 @@ subroutine write_energy(u, v, h, tv, day, n, G, GV, US, CS, tracer_CSp, dt_forci character(len=32) :: mesg_intro, time_units, day_str, n_str, date_str logical :: date_stamped type(time_type) :: dt_force !

Wallcraft" Date: Mon, 29 Jul 2024 15:43:35 +0000 Subject: [PATCH 1163/1329] Fix USE_CONT_THICKNESS bug Optionally correct a bug due to a missing halo exchange. This likely isn't needed when compiled for nonsymmetric memory, but the added halo exchange does no harm in such cases. The pass_vector call could probably be replaced with fill_symmetric_edges, except there is no subroutine fill_vector_symmetric_edges_3d. USE_CONT_THICKNESS is not yet widely used, so rather than preserving the old (incorrect) solutions by default, this bug is corrected by default. However, the previous answers can be recovered by setting the new runtime parameter USE_CONT_THICKNESS_BUG to true. This parameter is only used (and logged) when USE_CONT_THICKNESS set to true. By default, this commit does change answers in symmetric memory cases with USE_CONT_THICKNESS = True, and there is a new runtime parameter in such cases. --- .../lateral/MOM_hor_visc.F90 | 32 +++++++++++-------- 1 file changed, 19 insertions(+), 13 deletions(-) diff --git a/src/parameterizations/lateral/MOM_hor_visc.F90 b/src/parameterizations/lateral/MOM_hor_visc.F90 index 94afd0c858..a5f354beba 100644 --- a/src/parameterizations/lateral/MOM_hor_visc.F90 +++ b/src/parameterizations/lateral/MOM_hor_visc.F90 @@ -123,6 +123,7 @@ module MOM_hor_visc real :: min_grid_Ah !< Minimun horizontal biharmonic viscosity used to !! limit grid Reynolds number [L4 T-1 ~> m4 s-1] logical :: use_cont_thick !< If true, thickness at velocity points adopts h[uv] in BT_cont from continuity solver. + logical :: use_cont_thick_bug !< If true, retain an answer-changing bug for thickness at velocity points. type(ZB2020_CS) :: ZB2020 !< Zanna-Bolton 2020 control structure. logical :: use_ZB2020 !< If true, use Zanna-Bolton 2020 parameterization. @@ -282,9 +283,9 @@ subroutine horizontal_viscosity(u, v, h, uh, vh, diffu, diffv, MEKE, VarMix, G, type(thickness_diffuse_CS), optional, intent(in) :: TD !< Thickness diffusion control structure type(accel_diag_ptrs), optional, intent(in) :: ADp !< Acceleration diagnostics real, dimension(SZIB_(G),SZJ_(G),SZK_(GV)), & - optional, intent(in) :: hu_cont !< Layer thickness at u-points [H ~> m or kg m-2]. + optional, intent(inout) :: hu_cont !< Layer thickness at u-points [H ~> m or kg m-2]. real, dimension(SZI_(G),SZJB_(G),SZK_(GV)), & - optional, intent(in) :: hv_cont !< Layer thickness at v-points [H ~> m or kg m-2]. + optional, intent(inout) :: hv_cont !< Layer thickness at v-points [H ~> m or kg m-2]. !

Also some minor PEP8-like cleanups: * Some (but not all) 79+ character lines were reduced or split. * Some (but not all) single-letter variables were renamed. * A bad error handler for missing macros was fixed.

It is capable of detecting the instantaneous tidal signals while the model is running, and can be used to impose frequency-dependent wave drag or to de-tide model output. An example of filtering the M2 and K1 barotropic velocities is provided in the MOM_barotropic module. Added runtime flags for the M2 and K1 filters. Simplified the code by removing the control structure of the linked list, and now each filter has its own control structure. Using hor_index_type argument to avoid calculation in halo regions. --- src/core/MOM_barotropic.F90 | 70 +++++++++++ .../lateral/MOM_streaming_filter.F90 | 119 ++++++++++++++++++ 2 files changed, 189 insertions(+) create mode 100644 src/parameterizations/lateral/MOM_streaming_filter.F90 diff --git a/src/core/MOM_barotropic.F90 b/src/core/MOM_barotropic.F90 index e97e794cd6..0ac3e52a62 100644 --- a/src/core/MOM_barotropic.F90 +++ b/src/core/MOM_barotropic.F90 @@ -26,6 +26,8 @@ module MOM_barotropic use MOM_restart, only : query_initialized, MOM_restart_CS use MOM_self_attr_load, only : scalar_SAL_sensitivity use MOM_self_attr_load, only : SAL_CS +use MOM_streaming_filter, only : Filt_register, Filt_accum, Filter_CS +use MOM_tidal_forcing, only : tidal_frequency use MOM_time_manager, only : time_type, real_to_time, operator(+), operator(-) use MOM_unit_scaling, only : unit_scale_type use MOM_variables, only : BT_cont_type, alloc_bt_cont_type @@ -248,6 +250,10 @@ module MOM_barotropic logical :: linearized_BT_PV !< If true, the PV and interface thicknesses used !! in the barotropic Coriolis calculation is time !! invariant and linearized. + logical :: use_filter_m2 !< If true, apply streaming band-pass filter for detecting + !! instantaneous tidal signals. + logical :: use_filter_k1 !< If true, apply streaming band-pass filter for detecting + !! instantaneous tidal signals. logical :: use_wide_halos !< If true, use wide halos and march in during the !! barotropic time stepping for efficiency. logical :: clip_velocity !< If true, limit any velocity components that are @@ -291,6 +297,10 @@ module MOM_barotropic type(hor_index_type), pointer :: debug_BT_HI => NULL() !< debugging copy of horizontal index_type type(SAL_CS), pointer :: SAL_CSp => NULL() !< Control structure for SAL type(harmonic_analysis_CS), pointer :: HA_CSp => NULL() !< Control structure for harmonic analysis + type(Filter_CS) :: Filt_CS_um2, & !< Control structures for the M2 streaming filter + Filt_CS_vm2, & !< Control structures for the M2 streaming filter + Filt_CS_uk1, & !< Control structures for the K1 streaming filter + Filt_CS_vk1 !< Control structures for the K1 streaming filter logical :: module_is_initialized = .false. !< If true, module has been initialized integer :: isdw !< The lower i-memory limit for the wide halo arrays. @@ -598,6 +608,8 @@ subroutine btstep(U_in, V_in, eta_in, dt, bc_accel_u, bc_accel_v, forces, pbce, DCor_v, & !

Note that the full pressures were already being used everywhere apart from the calculation of the equation of state. This capability is controlled by the new runtime parameter SSH_IN_EOS_PRESSURE_FOR_PGF. This commit changes the Z_0p argument to int_density_dz and 8 other routines (int_density_dz_generic_pcm, int_density_dz_generic_plm, int_density_dz_generic_ppm, analytic_int_density_dz, int_density_dz_wright, int_density_dz_wright_full, int_density_dz_wright_red and int_density_dz_linear) from scalars into 2-d arrays, as were the internal z0pres arrays in most of these routines. By default, all answers are bitwise identical, but there is a new runtime parameter in the MOM_parameter_doc files for Boussinesq cases. --- src/core/MOM_PressureForce_FV.F90 | 32 ++++++++- src/core/MOM_density_integrals.F90 | 66 +++++++++++++------ src/equation_of_state/MOM_EOS.F90 | 3 +- src/equation_of_state/MOM_EOS_Wright.F90 | 21 ++++-- src/equation_of_state/MOM_EOS_Wright_full.F90 | 21 ++++-- src/equation_of_state/MOM_EOS_Wright_red.F90 | 22 +++++-- 6 files changed, 124 insertions(+), 41 deletions(-) diff --git a/src/core/MOM_PressureForce_FV.F90 b/src/core/MOM_PressureForce_FV.F90 index 9c4f355692..7b970f5686 100644 --- a/src/core/MOM_PressureForce_FV.F90 +++ b/src/core/MOM_PressureForce_FV.F90 @@ -63,6 +63,9 @@ module MOM_PressureForce_FV !! for the finite volume pressure gradient calculation. !!

The specific changes include correcting the grid passed to a call to initialize_ice_shelf in initialize_MOM, using a temporary mech_forcing type in add_shelf_forces when the grid is rotated, uncommenting and correcting the draft rotate_index code in initialize_ice_shelf, and correcting some error-checking and the grid passed to add_shelf_fluxes in initialize_ice_shelf_forces. In addition, unused hor_index_type elements were removed from the ice_shelf_CS, and some callTree calls were added to save_MOM_restart and initialize_ice_shelf. Without rotation, all answers are bitwise identical, but some cases that would have failed previously will now work. --- src/core/MOM.F90 | 11 ++- src/ice_shelf/MOM_ice_shelf.F90 | 158 +++++++++++++++++--------------- 2 files changed, 92 insertions(+), 77 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 2f5ac6e489..47971029cc 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -2955,20 +2955,20 @@ subroutine initialize_MOM(Time, Time_init, param_file, dirs, CS, & !

This includes both the density integral routines that are used primarily for Boussinesq cases and the specific volume integral routines that are primarily used with non-Boussinesq simulations. This change includes the addition of an optional SSH argument to int_density_dz and 6 other related routines (int_density_dz_generic_pcm, analytic_int_density_dz, int_density_dz_wright, int_density_dz_wright_full, int_density_dz_wright_red and int_density_dz_linear). It also includes the addition of an optional P_surf argument to int_specific_vol_dp and 7 other related routines (int_spec_vol_dp_generic_pcm, int_spec_vol_dp_generic_plm, analytic_int_specific_vol_dp int_spec_vol_dp_wright, int_spec_vol_dp_wright_full, int_spec_vol_dp_wright_red and int_spec_vol_dp_linear). Both of these new optional arguments are required when the new near-surface mass weighting is activated, and there are test that would issue a fatal error if they are not provided in such cases. (Note that these routines can be called from other places than the pressure gradient force calculation, in which case the calculations that need these fields are not done.) The diagnose_mass_weight_Z and diagnose_mass_weight_p diagnostic routines were similarly revised to mirror the expanded range of capabilities in the integral routines. This commit can change answers when MASS_WEIGHT_IN_PRESSURE_GRADIENT_TOP is true, but all answers are bitwise identical otherwise. There are new arguments to 15 publicly visible routines. --- src/core/MOM_PressureForce_FV.F90 | 16 +- src/core/MOM_density_integrals.F90 | 296 +++++++++++------- src/equation_of_state/MOM_EOS.F90 | 32 +- src/equation_of_state/MOM_EOS_Wright.F90 | 46 +-- src/equation_of_state/MOM_EOS_Wright_full.F90 | 46 +-- src/equation_of_state/MOM_EOS_Wright_red.F90 | 46 +-- src/equation_of_state/MOM_EOS_linear.F90 | 46 +-- 7 files changed, 325 insertions(+), 203 deletions(-) diff --git a/src/core/MOM_PressureForce_FV.F90 b/src/core/MOM_PressureForce_FV.F90 index 0dfa9d02de..41e1a85a61 100644 --- a/src/core/MOM_PressureForce_FV.F90 +++ b/src/core/MOM_PressureForce_FV.F90 @@ -277,25 +277,25 @@ subroutine PressureForce_FV_nonBouss(h, tv, PFu, PFv, G, GV, US, CS, ALE_CSp, p_ call int_spec_vol_dp_generic_plm( T_t(:,:,k), T_b(:,:,k), S_t(:,:,k), S_b(:,:,k), & p(:,:,K), p(:,:,K+1), alpha_ref, dp_neglect, p(:,:,nz+1), G%HI, & tv%eqn_of_state, US, dza(:,:,k), intp_dza(:,:,k), intx_dza(:,:,k), inty_dza(:,:,k), & - MassWghtInterp=CS%MassWghtInterp) + P_surf=p(:,:,1), MassWghtInterp=CS%MassWghtInterp) elseif ( CS%Recon_Scheme == 2 ) then call MOM_error(FATAL, "PressureForce_FV_nonBouss: "//& "int_spec_vol_dp_generic_ppm does not exist yet.") ! call int_spec_vol_dp_generic_ppm ( tv%T(:,:,k), T_t(:,:,k), T_b(:,:,k), & ! tv%S(:,:,k), S_t(:,:,k), S_b(:,:,k), p(:,:,K), p(:,:,K+1), & ! alpha_ref, G%HI, tv%eqn_of_state, dza(:,:,k), intp_dza(:,:,k), & - ! intx_dza(:,:,k), inty_dza(:,:,k)) + ! intx_dza(:,:,k), inty_dza(:,:,k), P_surf=p(:,:,1), MassWghtInterp=CS%MassWghtInterp) endif else call int_specific_vol_dp(tv_tmp%T(:,:,k), tv_tmp%S(:,:,k), p(:,:,K), & p(:,:,K+1), alpha_ref, G%HI, tv%eqn_of_state, & US, dza(:,:,k), intp_dza(:,:,k), intx_dza(:,:,k), & - inty_dza(:,:,k), bathyP=p(:,:,nz+1), dP_tiny=dp_neglect, & + inty_dza(:,:,k), bathyP=p(:,:,nz+1), P_surf=p(:,:,1), dP_tiny=dp_neglect, & MassWghtInterp=CS%MassWghtInterp) endif if ((CS%id_MassWt_u > 0) .or.

From 15fd31c22e016c54c57af94cfc0cfeff47064c4d Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Mon, 5 Aug 2024 09:50:01 -0400 Subject: [PATCH 1180/1329] *Non-Boussinesq code for RESET_INTXPA_INTEGRAL Added non-Boussinesq versions of the code that is exercised when CORRECTION_INTXPA_5PT and RESET_INTXPA_INTEGRAL are set to true. These options use the same names as in their Boussinesq forms, even though the arrays that are being adjusted are actually intx_za and inty_za. As a part of the testing of this commit, several checksums were added to the PressureForce_FV routines; these are enabled when DEBUG = True. The changes in this commit will change the answers in non-Boussinesq cases when either of those options are in use, but are bitwise identical when they are not, and all Boussinesq answers are bitwise identical. --- src/core/MOM_PressureForce_FV.F90 | 482 +++++++++++++++++++++++------- 1 file changed, 372 insertions(+), 110 deletions(-) diff --git a/src/core/MOM_PressureForce_FV.F90 b/src/core/MOM_PressureForce_FV.F90 index 869ef02520..8fa995d784 100644 --- a/src/core/MOM_PressureForce_FV.F90 +++ b/src/core/MOM_PressureForce_FV.F90 @@ -3,6 +3,7 @@ module MOM_PressureForce_FV !

Also extended the ranged of interfaces that can be used for the corrections to include the bottom interface and use the surface interface for the nonlinear pressure gradient force corrections either when the ocean surface interface is within the pressure or height range of the top cell, or when no appropriate interior interface has been found (for lack of a better idea). This latter case should probably be reconsidered later. This commit will change answers if RESET_INTXPA_INTEGRAL is true and one description of a runtime parameter in the MOM_parameter_doc files has been revised. --- src/core/MOM_PressureForce_FV.F90 | 313 ++++++++++++++++++++++++------ 1 file changed, 257 insertions(+), 56 deletions(-) diff --git a/src/core/MOM_PressureForce_FV.F90 b/src/core/MOM_PressureForce_FV.F90 index 8fa995d784..dedd86554c 100644 --- a/src/core/MOM_PressureForce_FV.F90 +++ b/src/core/MOM_PressureForce_FV.F90 @@ -447,7 +447,7 @@ subroutine PressureForce_FV_nonBouss(h, tv, PFu, PFv, G, GV, US, CS, ALE_CSp, p_ !

From bdf4b9e66ff28d4adf302d70d738e3e7cef627f0 Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Mon, 16 Sep 2024 05:42:42 -0400 Subject: [PATCH 1182/1329] +(*)Eliminate CORRECTION_INTXPA_5PT Eliminated the runtime parameter CORRECTION_INTXPA_5PT by always selecting the code that would have been used if it were true. This decision was based on the relative performance of the options with this set to true or false, and on the desire to maintain consistency with the 5-point Boole's rule quadrature used elsewhere in the pressure gradient force calculations. CORRECTION_INTXPA_5PT was only added in the same PR as this commit, so it can been simply removed and there is no need to obsolete it. This will change answers if CORRECTION_INTXPA or RESET_INTXPA_INTEGRAL are true and CORRECTION_INTXPA_5PT was set to false, but otherwise answers are bitwise identical.

There is now a default FCFLAGS macro which is used by the other two macros. One can now optionally configure FCFLAGS_DEBUG without worrying about the impact on FCFLAGS_FMS.

The answer_date, h_neglect and h_neglect_edge arguments to ALE_remap_scalar were also eliminated, as they are no longer used. The new routine open_boundary_setup_vert was added to manage these changes. A new verticalGrid_type argument was added to wave_speed_init. The h_neglect argument to 29 routines was made non-optional, because there is no way to provide a consistent hard-coded default for a dimensional parameter. The (mostly low-level) routines where this change to a non-optional h_neglect was made include build_reconstructions_1d, P1M_interpolation, P3M_interpolation, P3M_boundary_extrapolation, PLM_reconstruction, PLM_boundary_extrapolation, PPM_reconstruction, PPM_limiter_standard, PPM_boundary_extrapolation, PQM_reconstruction, PQM_limiter, PQM_boundary_extrapolation_v1, build_hycom1_column, build_rho_column, bound_edge_values, edge_values_explicit_h4, edge_values_explicit_h4cw, edge_values_implicit_h4, edge_slopes_implicit_h3, edge_slopes_implicit_h5, edge_values_implicit_h6, regridding_set_ppolys, build_and_interpolate_grid, remapByProjection, remapByDeltaZ, and integrateReconOnInterval. In two modules (MOM_open_boundary and MOM_wave_speed), two separate copies of remapping_CS variables were needed to accommodate different negligible thicknesses or units in different remapping calls. In those cases that also have an optional h_neglect_edge argument the default is now set to h_neglect. Improperly hard-coded dimensional default values for h_neglect or h_neglect_edge were eliminated in 16 places as a result of this change, but they were added back in 2 unit testing routines (one of these is archaic and unused) that do not use exercise dimensional rescaling tests. Because the previously optional arguments were already present in all calls from the dev/gfdl or main branches of the MOM6 code, and because the places where arguments have been removed they are balanced by equivalent arguments added to initialize_remapping, all answers are bitwise identical in the regression tests, but this change in interfaces could impact other code that is not in the main branch of MOM6. --- .../timing_tests/time_MOM_remapping.F90 | 7 +- src/ALE/MOM_ALE.F90 | 105 +++-------- src/ALE/MOM_remapping.F90 | 114 ++++++------ src/ALE/P1M_functions.F90 | 2 +- src/ALE/P3M_functions.F90 | 42 ++--- src/ALE/PLM_functions.F90 | 18 +- src/ALE/PPM_functions.F90 | 20 +- src/ALE/PQM_functions.F90 | 56 +++--- src/ALE/coord_hycom.F90 | 8 +- src/ALE/coord_rho.F90 | 8 +- src/ALE/regrid_edge_values.F90 | 112 ++++------- src/ALE/regrid_interp.F90 | 28 +-- src/ALE/remapping_attic.F90 | 38 ++-- src/core/MOM.F90 | 4 + src/core/MOM_open_boundary.F90 | 174 ++++++++++-------- src/diagnostics/MOM_diagnostics.F90 | 2 +- src/diagnostics/MOM_wave_speed.F90 | 41 +++-- src/framework/MOM_diag_remap.F90 | 24 +-- .../MOM_state_initialization.F90 | 61 +++--- .../MOM_tracer_initialization_from_Z.F90 | 27 +-- src/ocean_data_assim/MOM_oda_driver.F90 | 35 ++-- src/ocean_data_assim/MOM_oda_incupd.F90 | 47 ++--- .../lateral/MOM_internal_tides.F90 | 2 +- .../lateral/MOM_lateral_mixing_coeffs.F90 | 2 +- .../vertical/MOM_ALE_sponge.F90 | 37 ++-- .../vertical/MOM_tidal_mixing.F90 | 15 +- src/tracer/MOM_hor_bnd_diffusion.F90 | 21 +-- 27 files changed, 474 insertions(+), 576 deletions(-) diff --git a/config_src/drivers/timing_tests/time_MOM_remapping.F90 b/config_src/drivers/timing_tests/time_MOM_remapping.F90 index 5f4c0258ca..e4bea9d94f 100644 --- a/config_src/drivers/timing_tests/time_MOM_remapping.F90 +++ b/config_src/drivers/timing_tests/time_MOM_remapping.F90 @@ -17,8 +17,9 @@ program time_MOM_remapping real, dimension(nschemes) :: tmin !

FMS1 returns negative file handles for missing or otherwise error-prone files, but the FMS2 IO framework relies on `newunit=` to autogenerate handle IDs, which are always negative and cannot be used with checks for negative values. The check is replaced with equality with -1. `newunit` is guaranteed to never return -1 for a valid file, so this is a valid check for a missing file. It also lets us continue to use -1 as the initial (unopened) value. Behavior is compatible with `mpp_open()` output, so this can also be used with the FMS1 API. A better solution would be to introduce some validation function which is defined by each API, but there is not yet any need for such sophistication. --- src/diagnostics/MOM_PointAccel.F90 | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/src/diagnostics/MOM_PointAccel.F90 b/src/diagnostics/MOM_PointAccel.F90 index ab3c104d0f..30f080382c 100644 --- a/src/diagnostics/MOM_PointAccel.F90 +++ b/src/diagnostics/MOM_PointAccel.F90 @@ -121,11 +121,11 @@ subroutine write_u_accel(I, j, um, hin, ADp, CDp, dt, G, GV, US, CS, vel_rpt, st do_k(:) = .false. !

Separation of the file parser unit tests from the others was causing them to be exluded from report.cov.unit. This patch reworks the rules to replace MOM_file_parser_tests.F90.gcov with driver code, build/unit/test_%.F90.gcov. This does assume at all drivers will look the same (test_*.F90) but that part can be reworked if it ever becomes a problem in the future. Thanks to @adcroft for multiple suggestions in this PR. 2. Github appears to internally store all its repositories in another directory with the name as the repo (in this case MOM6/). Normally this is hidden to everyone, but it was causing some confusion with the codecov upload tool, and was unable to match the source code to the .gcov report. The .codecov.yml config file was modified to adjust for this path change, and should now correctly allow coverage to be reported alongside the file. (The GitHub Actions app likely makes this adjustment, but we need to do it manually since we upload directly to Codecov.io.) --- .codecov.yml | 3 +++ .github/workflows/coverage.yml | 14 ++++---------- .testing/Makefile | 11 ++++------- 3 files changed, 11 insertions(+), 17 deletions(-) diff --git a/.codecov.yml b/.codecov.yml index ae3b27aed3..838c421f66 100644 --- a/.codecov.yml +++ b/.codecov.yml @@ -8,3 +8,6 @@ coverage: default: threshold: 100% base: parent + +fixes: + - "MOM6/::" diff --git a/.github/workflows/coverage.yml b/.github/workflows/coverage.yml index 8b3dc944bd..22b9e471bc 100644 --- a/.github/workflows/coverage.yml +++ b/.github/workflows/coverage.yml @@ -19,17 +19,11 @@ jobs: - uses: ./.github/actions/testing-setup - - name: Compile file parser unit tests - run: make -j build/unit/test_MOM_file_parser - - - name: Run file parser unit tests - run: make run.cov.unit - - - name: Compile unit testing + - name: Compile unit tests run: make -j build.unit - - name: Run (single processor) unit tests - run: make run.unit + - name: Run unit tests + run: make run.cov.unit - name: Report unit test coverage to CI run: make report.cov.unit @@ -40,7 +34,7 @@ jobs: run: make -j build/cov/MOM6 - name: Run coverage tests - run: make -j -k run.cov + run: make -k run.cov - name: Report coverage to CI run: make report.cov diff --git a/.testing/Makefile b/.testing/Makefile index 18687a1616..a8a5ea3e68 100644 --- a/.testing/Makefile +++ b/.testing/Makefile @@ -222,8 +222,6 @@ build.prof: $(foreach b,opt opt_target,$(BUILD)/$(b)/MOM6) # Compiler flags # .testing dependencies -# TODO: We should probably build TARGET with the FMS that it was configured -# to use.

added function calc_sqg_struct in MOM_lateral_mixing_coeffs to compute sqg_struct - added sqg_expo to set the exponent of sqg_struct - to use sqg_struct for the backscatter, set BS_use_sqg=true, sqg_expo>0., and BS_EBT_power=0. - if SQG_USE_MEKE=True, use the eddy length scale from MEKE to compute sqg_struct - added eddy length scale Le in MEKE if SQG_USE_MEKE=True - added MEKE%Le into restart file if SQG_USE_MEKE=True - added MEKE in Varmix - registered N2_u and N2_v diagnostics when SQG_EXPO>0 (cherry picked from commit 6d3df0541c33d6f6d1f9fcb695f1a1eb961ec1b3) * Compute vertical structures for khth, khtr, backscatter, and kdgl90 all in VarMix - Vertical structures including khth_struct, khtr_struct, BS_struct, and kdgl90_struct are now computed in VarMix - Each diffusivity/viscosity have two vertical structure options, equivalent barotropic (EBT) and surface quasigeostrophic (SQG) mode structures - KHTH_USE_EBT_STRUCT, KHTR_USE_EBT_STRUCT, KDGL90_USE_EBT_STRUCT and BS_EBT_POWER parameters, which already existed, still control whether to use the EBT structure for khth, khtr, kdgl90, and backscatter, respectively - Added KHTH_USE_SQG_STRUCT, KHTR_USE_SQG_STRUCT, KDGL90_USE_SQG_STRUCT and BS_USE_SQG parameters to control whether to use the SQG structure for khth, khtr, kdgl90, and backscatter, respectively - If neither EBT nor SQG is called, no vertical structure will be used for that diffusivity/viscosity - An error will be called if both EBT and SQG structures are called for the same diffusivity/viscosity - Added dt as an input of calc_resoln_function. dt is needed for calc_sqg_struct called in calc_resoln_function Bug fixes - Changed ()**0.5 to sqrt in sqg_struct, which solves the dimension error - Added if statement for using BS_struct in MOM_hor_visc - Added if statement for CS%sqg_struct<=0. - Changed the subroundoff of Coriolis parameter to 1e-40 in calc_sqg_struct -

(Curiously, using exactly 20190101 actually gives the intended result.) This commit modifies this logic so that the older (mildly dimensionally inconsistent) version is now being used for answer dates between 20190102 and 20241201, but a very late answer date uses the corrected form. The offending block of code is only used when USE_MEKE is true and the Rossby number scaling of the biharmonic energy source is enabled by setting MEKE_BACKSCAT_RO_C > 0, which does not appear to be very common. To avoid logging the description of this ugly new logic in MOM_parameter_doc files where it does not impact the solutions, new logic was added to limit the logging of HOR_VISC_ANSWER_DATE. Also, as there are no known non-Boussinesq cases with this combination of MEKE parameters, the minimum value of HOR_VISC_ANSWER_DATE was changed to 20241201 when the model is in non-Boussinesq mode. Because this bug went undetected when it was first introduced, it probably is not widely used, and it might make sense to obsolete HOR_VISC_ANSWER_DATE and eliminate the older, inconsistent block of code. This commit could change answers for answer dates that are above 20241201 with the MEKE Rossby number scaling enabled via MEKE_BACKSCAT_RO_C > 0. --- .../lateral/MOM_hor_visc.F90 | 25 +++++++++++++------ 1 file changed, 17 insertions(+), 8 deletions(-) diff --git a/src/parameterizations/lateral/MOM_hor_visc.F90 b/src/parameterizations/lateral/MOM_hor_visc.F90 index fa5bb40577..92794c54e7 100644 --- a/src/parameterizations/lateral/MOM_hor_visc.F90 +++ b/src/parameterizations/lateral/MOM_hor_visc.F90 @@ -2141,7 +2141,7 @@ subroutine horizontal_viscosity(u, v, h, uh, vh, diffu, diffv, MEKE, VarMix, G, Shear_mag_bc = sqrt(sh_xx(i,j) * sh_xx(i,j) + & 0.25*(((sh_xy(I-1,J-1)*sh_xy(I-1,J-1)) + (sh_xy(I,J)*sh_xy(I,J))) + & ((sh_xy(I-1,J)*sh_xy(I-1,J)) + (sh_xy(I,J-1)*sh_xy(I,J-1))))) - if (CS%answer_date > 20190101) then + if ((CS%answer_date > 20190101) .and.

This commit adds the optional `defaults=` argument that must have the same length as the `values` argument. I've also added a few instances of this optional argument: - by adding the `initialize_thickness_param()` procedure, selected by `THICKNESS_CONFIG = "param"`. The procedure was based on the "uniform" method, and uses the parameter `THICKNESS_INIT_VALUES` which defaults to uniform values derived from `MAXIMUM_DEPTH` - the setting of MLD_EN_VALS in MOM_diabatic_driver.F90 which was previously using a work around to set defaults to 25, 2500, 250000 J/m2. - two vectors of 4 values in user/user_change_diffusivity.F90 There will be some doc file changes, but no answer changes. --- src/framework/MOM_document.F90 | 11 +++- src/framework/MOM_file_parser.F90 | 22 +++++-- .../MOM_state_initialization.F90 | 65 +++++++++++++++++++ .../vertical/MOM_diabatic_driver.F90 | 9 +-- src/user/user_change_diffusivity.F90 | 5 +- 5 files changed, 95 insertions(+), 17 deletions(-) diff --git a/src/framework/MOM_document.F90 b/src/framework/MOM_document.F90 index f32573815f..eceb87d7d4 100644 --- a/src/framework/MOM_document.F90 +++ b/src/framework/MOM_document.F90 @@ -303,14 +303,16 @@ subroutine doc_param_real(doc, varname, desc, units, val, default, debuggingPara end subroutine doc_param_real !> This subroutine handles parameter documentation for arrays of reals. -subroutine doc_param_real_array(doc, varname, desc, units, vals, default, debuggingParam, like_default) +subroutine doc_param_real_array(doc, varname, desc, units, vals, default, defaults, & + debuggingParam, like_default) type(doc_type), pointer :: doc !< A pointer to a structure that controls where the !! documentation occurs and its formatting character(len=*), intent(in) :: varname !< The name of the parameter being documented character(len=*), intent(in) :: desc !< A description of the parameter being documented character(len=*), intent(in) :: units !< The units of the parameter being documented real, intent(in) :: vals(:) !< The array of values to record - real, optional, intent(in) :: default !< The default value of this parameter + real, optional, intent(in) :: default !< A uniform default value of this parameter + real, optional, intent(in) :: defaults(:) !< The element-wise default values of this parameter logical, optional, intent(in) :: debuggingParam !< If present and true, this is a debugging parameter. logical, optional, intent(in) :: like_default !< If present and true, log this parameter as though !! it has the default value, even if there is no default. @@ -334,6 +336,11 @@ subroutine doc_param_real_array(doc, varname, desc, units, vals, default, debugg do i=1,size(vals) ; if (vals(i) /= default) equalsDefault = .false. ; enddo mesg = trim(mesg)//" default = "//trim(real_string(default)) endif + if (present(defaults)) then + equalsDefault = .true. + do i=1,size(vals) ; if (vals(i) /= defaults(i)) equalsDefault = .false. ; enddo + mesg = trim(mesg)//" default = "//trim(real_array_string(defaults)) + endif if (present(like_default)) then ; if (like_default) equalsDefault = .true. ; endif if (mesgHasBeenDocumented(doc, varName, mesg)) return !

Previously, it was a safe assumption that both would be built with double precision, but this is no longer the case since FMS now supports both single and double precision. This could cause conflicts with mixed-precision builds. This patch converts the values from FMS-precision to MOM-precision. Single->double should not affect reproducibility since every single-precision number can be exactly represented in double precision. Double->single could affect reproducibility, but this is not an issue since MOM6 does not run in single precision. --- config_src/infra/FMS1/MOM_constants.F90 | 10 +++++++--- config_src/infra/FMS2/MOM_constants.F90 | 10 +++++++--- 2 files changed, 14 insertions(+), 6 deletions(-) diff --git a/config_src/infra/FMS1/MOM_constants.F90 b/config_src/infra/FMS1/MOM_constants.F90 index 2db177e08c..a632267a7f 100644 --- a/config_src/infra/FMS1/MOM_constants.F90 +++ b/config_src/infra/FMS1/MOM_constants.F90 @@ -3,12 +3,16 @@ module MOM_constants !

These have MKS units [rad s-1] but they are all currently listed as [s-1]. Updated dOxygen comments for variables, e.g. [T-1 ~> s-1] becomes [rad T-1 ~> rad s-1]. Updated get_param units. e.g. units="s-1" becomes units="rad s-1". No answers are changed, but the logged parameter units are different.

section_vertical_reconstruction Vertical Reconstruction Methods + +Within the ALE or Lagrangian Remap Method (LRM), the structure of fields within cells (or layers in the case of MOM6) are reconstructed from the resolved cell means (i.e. the model variables). +The most widely used reconstructions use a piecewise polynomial representation for the reconstruction within each cell. +The simplest of these is the Piecewise Constant Method (PCM) which simply uses the cell mean value as a constant value throughout the cell. +The reconstructed fields may be discontinuous across cell boundaries, which is inherently the case for PCM. +PCM is a first order method and considered too diffusive for ALE, although it is the implicit representation in the traditional "layered" mode. +A second order reconstruction if the Piecewise Linear Method (PLM) of Van Leer, 1977 \cite van_leer_1977. +Higher order reconstructions are the Piecwise Parabloic Method (PPM) of Colella and Woodward, 1984 \cite colella1984, and the Piecwise Quartic Method (PQM) of White and Adcroft, 2008 \cite white2008. + +\section section_vertical_reconstruction_implementation Implementation + +The original implementations of vertical reconstructions are available in the `src/ALE` directory via modules such as plm_functions, ppm_functions, regrid_edge_values, etc. +These versions were used in OM4 \cite Adcroft2019 but later found to have inaccuracies with regard to round-off errors that could lead to non-monotonic behaviors. +A revision of the schemes was made available after comparing and porting from Hycom and are available via modules such as mom_hybgen_remap. +A recent refactoring of reconstructions for remapping was implemented via classes derived from the recon1d_type (also in `src/ALE` directory). + +The following table summarizes the OM4-era and Hycom-ported methods and routines, all selected by the runtime parameter `REMAPPING_SCHEME`. +The branch points (`select case`) in the

This is controlled by the new runtime parameter EPBL_OPTIONS_DIFF, which is an integer that specifies which options to change or 0 (the default) to disable this capability. Associated with this are the new diagnostics ePBL_opt_diff_Kd_ePBL, ePBL_opt_maxdiff_Kd_ePBL and ePBL_opt_diff_h_ML, which only are registered when the differencing is enabled. For now, only changes associated with the settings of EPBL_ORIGINAL_PE_CALC and EPBL_ANSWER_DATE can be evaluated, but this list will grow as new options are added. As a part of these changes, there were some other reforms to the way that MOM_energetic_PBL handles diagnostics, with the 2-d and 3-d arrays changed from allocatable arrays with enduring memory commitments in the energetic_PBL_CS type into simple arrays in energetic_PBL, relying on the fact that compilers will be smart enough to avoid actually allocating this memory when it is unused to avoid expanding the overall memory requirements of MOM6. A number of allocate and deallocate calls were eliminated by these changes. In addition, explicit 'units=' descriptors were added to numerous register_diag_field calls to help identify inconsistent conversion factors. Also, the diagnostic of the number of boundary layer depth iterations was added to the ePBL_column_diags, which enabled the intent of the CS and G arguments to ePBL_column to be changed to intent(in). The unnecessary extra logic associated with the use of the OBL_converged variable in ePBL_column was eliminated, but the results are uneffected. Because the MOM_parameter_doc files were changing anyway, and because this commit is only a diagnostic change, about 6 spelling errors were corrected in ePBL parameter descriptions as a part of this commit. All answers are bitwise identical, but there is a new runtime parameter and there may be new diagnostics depending on the choice of a non-default value for that new parameter. --- .../vertical/MOM_energetic_PBL.F90 | 415 +++++++++++------- 1 file changed, 247 insertions(+), 168 deletions(-) diff --git a/src/parameterizations/vertical/MOM_energetic_PBL.F90 b/src/parameterizations/vertical/MOM_energetic_PBL.F90 index 8b476a5e8d..cfbe22bb44 100644 --- a/src/parameterizations/vertical/MOM_energetic_PBL.F90 +++ b/src/parameterizations/vertical/MOM_energetic_PBL.F90 @@ -94,9 +94,8 @@ module MOM_energetic_PBL !!

This can be used when ePBL does not convert released mean kinetic energy into turbulent kinetic energy (i.e., if MKE_TO_TKE_EFFIC = 0.) and is more efficient than the more general iterative approach. To preserve old answers, this new option is only enabled for the surface boundary layer when the new runtime parameter DIRECT_EPBL_MIXING_CALC is set to true. This new option can be tested passively by setting EPBL_OPTIONS_DIFF to 3 in a run that uses ePBL. By default all answers are bitwise identical, but there is a new runtime parameter in some of the MOM_parameter_doc files. --- .../vertical/MOM_energetic_PBL.F90 | 208 +++++++++++++++++- 1 file changed, 207 insertions(+), 1 deletion(-) diff --git a/src/parameterizations/vertical/MOM_energetic_PBL.F90 b/src/parameterizations/vertical/MOM_energetic_PBL.F90 index cfbe22bb44..579022d1dd 100644 --- a/src/parameterizations/vertical/MOM_energetic_PBL.F90 +++ b/src/parameterizations/vertical/MOM_energetic_PBL.F90 @@ -69,6 +69,10 @@ module MOM_energetic_PBL real :: MKE_to_TKE_effic !< The efficiency with which mean kinetic energy released by !! mechanically forced entrainment of the mixed layer is converted to !!

This new option is enabled by setting the new runtime parameter EPBL_BBL_EFFIC to be positive. If both EPBL_BBL_EFFIC and BBL_EFFIC are set to positive values, there is a risk of double-counting, but this case is not being trapped for now. The changes include the addition of a new mandatory vertvisc_type argument to the publicly visible routine energetic_PBL. When this new ePBL bottom boundary layer mixing option is enabled, there are several new diagnostics available that are related to bottom boundary layer mixing. Several new checksum calls were also added with this new option when DEBUG = True. The MOM_parameter_doc files are altered by the addition of two new runtime parameters, and by the correction of several spelling errors in the descriptions of other ePBL parameters. By default, all answers are bitwise identical. --- .../vertical/MOM_diabatic_driver.F90 | 4 +- .../vertical/MOM_energetic_PBL.F90 | 1078 +++++++++++++++-- 2 files changed, 1000 insertions(+), 82 deletions(-) diff --git a/src/parameterizations/vertical/MOM_diabatic_driver.F90 b/src/parameterizations/vertical/MOM_diabatic_driver.F90 index e984d5831c..819b06ee50 100644 --- a/src/parameterizations/vertical/MOM_diabatic_driver.F90 +++ b/src/parameterizations/vertical/MOM_diabatic_driver.F90 @@ -858,7 +858,7 @@ subroutine diabatic_ALE_legacy(u, v, h, tv, BLD, fluxes, visc, ADp, CDp, dt, Tim endif call find_uv_at_h(u, v, h, u_h, v_h, G, GV, US) - call energetic_PBL(h, u_h, v_h, tv, fluxes, dt, Kd_ePBL, G, GV, US, & + call energetic_PBL(h, u_h, v_h, tv, fluxes, visc, dt, Kd_ePBL, G, GV, US, & CS%ePBL, stoch_CS, dSV_dT, dSV_dS, cTKE, SkinBuoyFlux, waves=waves) call energetic_PBL_get_MLD(CS%ePBL, BLD(:,:), G, US) @@ -1410,7 +1410,7 @@ subroutine diabatic_ALE(u, v, h, tv, BLD, fluxes, visc, ADp, CDp, dt, Time_end, endif call find_uv_at_h(u, v, h, u_h, v_h, G, GV, US) - call energetic_PBL(h, u_h, v_h, tv, fluxes, dt, Kd_ePBL, G, GV, US, & + call energetic_PBL(h, u_h, v_h, tv, fluxes, visc, dt, Kd_ePBL, G, GV, US, & CS%ePBL, stoch_CS, dSV_dT, dSV_dS, cTKE, SkinBuoyFlux, waves=waves) call energetic_PBL_get_MLD(CS%ePBL, BLD(:,:), G, US) diff --git a/src/parameterizations/vertical/MOM_energetic_PBL.F90 b/src/parameterizations/vertical/MOM_energetic_PBL.F90 index 579022d1dd..b2b80675a0 100644 --- a/src/parameterizations/vertical/MOM_energetic_PBL.F90 +++ b/src/parameterizations/vertical/MOM_energetic_PBL.F90 @@ -5,6 +5,7 @@ module MOM_energetic_PBL use MOM_cpu_clock, only : cpu_clock_id, cpu_clock_begin, cpu_clock_end, CLOCK_ROUTINE use MOM_coms, only : EFP_type, real_to_EFP, EFP_to_real, operator(+), assignment(=), EFP_sum_across_PEs +use MOM_debugging, only : hchksum use MOM_diag_mediator, only : post_data, register_diag_field, safe_alloc_alloc use MOM_diag_mediator, only : time_type, diag_ctrl use MOM_domains, only : create_group_pass, do_group_pass, group_pass_type @@ -16,7 +17,7 @@ module MOM_energetic_PBL use MOM_intrinsic_functions, only : cuberoot use MOM_string_functions, only : uppercase use MOM_unit_scaling, only : unit_scale_type -use MOM_variables, only : thermo_var_ptrs +use MOM_variables, only : thermo_var_ptrs, vertvisc_type use MOM_verticalGrid, only : verticalGrid_type use MOM_wave_interface, only : wave_parameters_CS, Get_Langmuir_Number use MOM_stochastics, only : stochastic_CS @@ -160,6 +161,11 @@ module MOM_energetic_PBL !! the Ekman depth over the Obukhov depth with destabilizing forcing [nondim]. real :: Max_Enhance_M = 5. !< The maximum allowed LT enhancement to the mixing [nondim]. + !/ Bottom boundary layer mixing related options + real :: ePBL_BBL_effic !< The efficiency of bottom boundary layer mixing via ePBL [nondim] + logical :: Use_BBLD_iteration !< If true, use the proximity to the top of the actively turbulent + !! bottom boundary layer to constrain the mixing lengths. + !/ Options for documenting differences from parameter choices integer :: options_diff !< If positive, this is a coded integer indicating a pair of !! settings whose differences are diagnosed in a passive diagnostic mode @@ -188,14 +194,20 @@ module MOM_energetic_PBL real, allocatable, dimension(:,:) :: & ML_depth !< The mixed layer depth determined by active mixing in ePBL, which may !! be used for the first guess in the next time step [H ~> m or kg m-2] + real, allocatable, dimension(:,:) :: & + BBL_depth !< The bottom boundary layer depth determined by active mixing in ePBL [H ~> m or kg m-2] type(EFP_type), dimension(2) :: sum_its !< The total number of iterations and columns worked on + type(EFP_type), dimension(2) :: sum_its_BBL !< The total number of iterations and columns worked on !>@{ Diagnostic IDs integer :: id_ML_depth = -1, id_hML_depth = -1, id_TKE_wind = -1, id_TKE_mixing = -1 integer :: id_TKE_MKE = -1, id_TKE_conv = -1, id_TKE_forcing = -1 integer :: id_TKE_mech_decay = -1, id_TKE_conv_decay = -1 integer :: id_Mixing_Length = -1, id_Velocity_Scale = -1 + integer :: id_Kd_BBL = -1, id_BBL_Mix_Length = -1, id_BBL_Vel_Scale = -1 + integer :: id_TKE_BBL = -1, id_TKE_BBL_mixing = -1, id_TKE_BBL_decay = -1 + integer :: id_ustar_BBL = -1, id_BBL_decay_scale = -1, id_BBL_depth = -1 integer :: id_MSTAR_mix = -1, id_LA_mod = -1, id_LA = -1, id_MSTAR_LT = -1 !

This new capability is enabled by the new runtime parameter DECAY_ADJUSTED_BBL_TKE and is implemented via the new internal function exp_decay_TKE_adjust. In addition, this commit adds 9 bottom-boundary layer specific run-time parameters that are analogous to parameters that set the properties of the surface-driven mixing, and take their defaults from them, but can now be set independently for the bottom boundary layer. The inefficient option to use bisection to estimate the bottom boundary layer depth was eliminated, as it certain that it is not being used yet in any cases, and it should be deprecated for the estimation of the surface boundary layer. By default, all answers are bitwise identical, but there are up to 10 new runtime parameters that will appear in some MOM_parameter_doc files. --- .../vertical/MOM_energetic_PBL.F90 | 347 ++++++++++++++---- 1 file changed, 275 insertions(+), 72 deletions(-) diff --git a/src/parameterizations/vertical/MOM_energetic_PBL.F90 b/src/parameterizations/vertical/MOM_energetic_PBL.F90 index b2b80675a0..d60e08670c 100644 --- a/src/parameterizations/vertical/MOM_energetic_PBL.F90 +++ b/src/parameterizations/vertical/MOM_energetic_PBL.F90 @@ -165,6 +165,32 @@ module MOM_energetic_PBL real :: ePBL_BBL_effic !< The efficiency of bottom boundary layer mixing via ePBL [nondim] logical :: Use_BBLD_iteration !< If true, use the proximity to the top of the actively turbulent !! bottom boundary layer to constrain the mixing lengths. + real :: TKE_decay_BBL !< The ratio of the natural Ekman depth to the TKE decay scale for + !! bottom boundary layer mixing [nondim] + real :: min_BBL_mix_len !< The minimum mixing length scale that will be used by ePBL in the bottom + !! boundary layer mixing [Z ~> m].

As a result of these changes, 15 rescaling factors were eliminated or moved toward the end of write_energy().

This commit adds an optional `defaults=` argument to get_param_int_array(), doc_param_int_array() and log_param_int_array() to allow for the specification of an array of default values. These additions are analogous to what had previously been added for real arrays in github.com/NOAA-GFDL/MOM6/pull/760. This commit also adds the new internal function int_array_string(), analogous to real_array_string(), in MOM_document. This differs slightly from its real array counterpart in that it only uses the syntax like `3*75` for lists of integers that are longer than we would use to specify dates and times or pairs of layout parameters, because "(0, 0)" seems more readily interpretable than "(2*0)".

Even if the total work is reduced, they are likely to interrupt pipelines. When EY24_EBT_BS is disabled, they will clearly reduce performance. This patch moves those tests outside of the if-block and applies them separately.

The interface changes include revising the order of the arguments, making the weight argument options, replacing the scale argument with an optional tmp_scale argument that is the inverse of the previous scale, and making the default for the use of reproducing sums to be true when the answer_date argument is absent. The two homogenize_field routines now give equivalent behavior when none of the optional arguments to homogenize_field() are absent. The homogenize_field calls in MOM_temp_salt_initialize_from_Z() and the horiz_interp_and_extrap_tracer() routines have been modified in accordance with the interface changes. All answers are bitwise identical, but the interface to a publicly visible routine has been substantially changed to the point where any calls using the previous interface will not compile. --- src/framework/MOM_horizontal_regridding.F90 | 56 +++++++++++-------- .../MOM_state_initialization.F90 | 4 +- 2 files changed, 34 insertions(+), 26 deletions(-) diff --git a/src/framework/MOM_horizontal_regridding.F90 b/src/framework/MOM_horizontal_regridding.F90 index 324808e374..8e988ccce8 100644 --- a/src/framework/MOM_horizontal_regridding.F90 +++ b/src/framework/MOM_horizontal_regridding.F90 @@ -591,7 +591,7 @@ subroutine horiz_interp_and_extrap_tracer_record(filename, varnam, recnum, G, tr !

After this commit, all of the dimensional scaling factors for diagnostics in the ice_shelf code occur via conversion factors that are immediately adjacent to the declaration of the units of those diagnostics, facilitating comparison for consistency. The declared units of one diagnostic, "taub_beta", were revised from "MPa s m-1" to "MPa yr m-1" to be consistent with its conversion factor, which was also corrected (essentially by a factor of [Z L-1 ~> 1]. Several missing unit conversion factors for rates of mass change were also added, and about 15 missing or incorrect units in lines documenting real variables were added or fixed. The input scale factor for the (perhaps unused) variable INPUT_VEL_ICE_SHELF was corrected from `US%m_s_to_L_T*US%m_to_Z` to just `US%m_s_to_L_T`. With these changes, all solutions are bitwise identical, apart from regional cases with a specified inflow when run with dimensional rescaling. The ice shelf diagnostics should now be invariant when dimensional rescaling is applied, and the units of the ice shelf diagnostics are now all consistent with the required rescaling factors. --- src/ice_shelf/MOM_ice_shelf.F90 | 187 ++++++++++++--------- src/ice_shelf/MOM_ice_shelf_dynamics.F90 | 27 +-- src/ice_shelf/MOM_ice_shelf_initialize.F90 | 4 +- 3 files changed, 124 insertions(+), 94 deletions(-) diff --git a/src/ice_shelf/MOM_ice_shelf.F90 b/src/ice_shelf/MOM_ice_shelf.F90 index 582518d4f1..ac12f18c9d 100644 --- a/src/ice_shelf/MOM_ice_shelf.F90 +++ b/src/ice_shelf/MOM_ice_shelf.F90 @@ -353,8 +353,8 @@ subroutine shelf_calc_flux(sfc_state_in, fluxes_in, Time, time_step_in, CS) character(len=160) :: mesg !

If these parameters are set to 31, the month returned by the FMS `get_date()` function sets the time level. If they are set to 0 (the default) the previous behavior is obtained, in which the time level is determined from the number of records in the file. To always take the first record in the file, set these parameters to large values (greater than 1000000 will always work, but in practice smaller values do the same thing). By default all answers are bitwise identical, but there are up to 10 new runtime parameters in some MOM_parameter_doc files for cases that have `WIND_CONFIG = "file"` or `BUOY_CONFIG = "file"`. The list of new runtime parameters is `WIND_FILE_DAYS_PER_RECORD`, `LONGWAVE_FILE_DAYS_PER_RECORD`, `SHORTWAVE_FILE_DAYS_PER_RECORD`, `EVAPORATION_FILE_DAYS_PER_RECORD`, `LATENTHEAT_FILE_DAYS_PER_RECORD`, `SENSIBLEHEAT_FILE_DAYS_PER_RECORD`, `RAIN_FILE_DAYS_PER_RECORD`, `SHORTWAVE_FILE_DAYS_PER_RECORD`, `RUNOFF_FILE_DAYS_PER_RECORD`, `SSTRESTORE_FILE_DAYS_PER_RECORD` and `SALINITYRESTORE_FILE_DAYS_PER_RECORD`. The problem identified in github.com/NOAA-GFDL/MOM6/issues/631 is addressed by this commit, and that issue can be closed once this commit is merged onto the main branch of MOM6. --- .../solo_driver/MOM_surface_forcing.F90 | 316 +++++++++++------- 1 file changed, 193 insertions(+), 123 deletions(-) diff --git a/config_src/drivers/solo_driver/MOM_surface_forcing.F90 b/config_src/drivers/solo_driver/MOM_surface_forcing.F90 index 967667d786..448b16b5e4 100644 --- a/config_src/drivers/solo_driver/MOM_surface_forcing.F90 +++ b/config_src/drivers/solo_driver/MOM_surface_forcing.F90 @@ -30,13 +30,12 @@ module MOM_surface_forcing use MOM_grid, only : ocean_grid_type use MOM_get_input, only : Get_MOM_Input, directories use MOM_io, only : file_exists, MOM_read_data, MOM_read_vector, slasher -use MOM_io, only : read_netCDF_data -use MOM_io, only : EAST_FACE, NORTH_FACE, num_timelevels +use MOM_io, only : read_netCDF_data, EAST_FACE, NORTH_FACE, num_timelevels use MOM_restart, only : register_restart_field, restart_init, MOM_restart_CS use MOM_restart, only : restart_init_end, save_restart, restore_state -use MOM_time_manager, only : time_type, operator(+), operator(/), get_time, time_type_to_real -use MOM_tracer_flow_control, only : call_tracer_set_forcing -use MOM_tracer_flow_control, only : tracer_flow_control_CS +use MOM_time_manager, only : time_type, operator(+), operator(/), operator(*) +use MOM_time_manager, only : set_time, get_time, get_date, time_type_to_real +use MOM_tracer_flow_control, only : call_tracer_set_forcing, tracer_flow_control_CS use MOM_unit_scaling, only : unit_scale_type use MOM_variables, only : surface use MESO_surface_forcing, only : MESO_buoyancy_forcing @@ -51,10 +50,10 @@ module MOM_surface_forcing use SCM_CVmix_tests, only : SCM_CVmix_tests_wind_forcing use SCM_CVmix_tests, only : SCM_CVmix_tests_buoyancy_forcing use SCM_CVmix_tests, only : SCM_CVmix_tests_CS -use BFB_surface_forcing, only : BFB_buoyancy_forcing -use BFB_surface_forcing, only : BFB_surface_forcing_init, BFB_surface_forcing_CS -use dumbbell_surface_forcing, only : dumbbell_surface_forcing_init, dumbbell_surface_forcing_CS -use dumbbell_surface_forcing, only : dumbbell_buoyancy_forcing +use BFB_surface_forcing, only : BFB_buoyancy_forcing +use BFB_surface_forcing, only : BFB_surface_forcing_init, BFB_surface_forcing_CS +use dumbbell_surface_forcing, only : dumbbell_surface_forcing_init, dumbbell_surface_forcing_CS +use dumbbell_surface_forcing, only : dumbbell_buoyancy_forcing implicit none ; private @@ -102,8 +101,6 @@ module MOM_surface_forcing real, pointer :: S_Restore(:,:) => NULL() !< salinity to damp (restore) the SSS [S ~> ppt] real, pointer :: Dens_Restore(:,:) => NULL() !< density to damp (restore) surface density [R ~> kg m-3] - integer :: buoy_last_lev_read = -1 !< The last time level read from buoyancy input files - ! if WIND_CONFIG=='gyres' then use the following as = A, B, C and n respectively for ! taux = A + B*sin(n*pi*y/L) + C*cos(n*pi*y/L) real :: gyres_taux_const !< A constant wind stress [R L Z T-2 ~> Pa]. @@ -181,6 +178,38 @@ module MOM_surface_forcing character(len=80) :: SST_restore_var = '' !< target sea surface temperature variable name in the input file character(len=80) :: SSS_restore_var = '' !< target sea surface salinity variable name in the input file + !

Bottom pressure anomaly should really be used for general purposes. * New runtime parameter A runtime parameter SAL_USE_BPA is added to use bottom pressure anomaly. The option requires an input file for long term mean reference bottom pressure. The reference bottom pressure field is stored with SAL_CS. * Refactor SAL and tides in Boussinesq mode As the total bottom pressure is needed for bottom pressure anomaly, SAL calculation in Boussinesq mode needs to be refactored. In addition, there is a longstanding bug in Boussinesq mode that interface height is modified by SAL and tides, and the modified interface height is erroneously used for density and pressure calculation later on. Therefore the SAL and tides are refactored by moving their calculations after pressure is calculated. Tide answers before 20230630 is retained. Answers after 20230630 are changed for Boussinesq mode. --- src/core/MOM_PressureForce_FV.F90 | 158 +++++++------ src/core/MOM_dynamics_split_RK2.F90 | 2 +- src/core/MOM_dynamics_split_RK2b.F90 | 2 +- src/core/MOM_dynamics_unsplit.F90 | 2 +- src/core/MOM_dynamics_unsplit_RK2.F90 | 2 +- .../lateral/MOM_self_attr_load.F90 | 211 ++++++++++++------ 6 files changed, 238 insertions(+), 139 deletions(-) diff --git a/src/core/MOM_PressureForce_FV.F90 b/src/core/MOM_PressureForce_FV.F90 index 905df97d68..8fec00fb90 100644 --- a/src/core/MOM_PressureForce_FV.F90 +++ b/src/core/MOM_PressureForce_FV.F90 @@ -39,8 +39,10 @@ module MOM_PressureForce_FV !> Finite volume pressure gradient control structure type, public :: PressureForce_FV_CS ; private logical :: initialized = .false. !< True if this control structure has been initialized. - logical :: calculate_SAL !< If true, calculate self-attraction and loading. - logical :: tides !< If true, apply tidal momentum forcing. + logical :: calculate_SAL = .false. !< If true, calculate self-attraction and loading. + logical :: sal_use_bpa = .false. !< If true, use bottom pressure anomaly instead of SSH + !! to calculate SAL. + logical :: tides = .false. !< If true, apply tidal momentum forcing. real :: Rho0 !< The density used in the Boussinesq !! approximation [R ~> kg m-3]. real :: GFS_scale !< A scaling of the surface pressure gradients to @@ -80,7 +82,7 @@ module MOM_PressureForce_FV !! equation of state is 0 to account for the displacement of the sea !! surface including adjustments for atmospheric or sea-ice pressure. logical :: use_stanley_pgf !< If true, turn on Stanley parameterization in the PGF - integer :: tides_answer_date !< Recover old answers with tides in Boussinesq mode + integer :: tides_answer_date = 99991231 !< Recover old answers with tides integer :: id_e_tide = -1 !< Diagnostic identifier integer :: id_e_tide_eq = -1 !< Diagnostic identifier integer :: id_e_tide_sal = -1 !< Diagnostic identifier @@ -217,6 +219,7 @@ subroutine PressureForce_FV_nonBouss(h, tv, PFu, PFv, G, GV, US, CS, ALE_CSp, p_ real :: dp_neglect !

Notably, `e_sal_tide` is renamed to `e_sal_and_tide` (the summation of sal and tide), not to be confused with `e_tide_sal`, which is renamed to `e_tidal_sal` (sal from tides). * Fix e_tidal diagnostics in Boussinesq mode.

The current method adjusts interface heights with geopotential height anomaly for SAL and tides.

For Boussinesq mode, there is a baroclinic component of tidal forcing and SAL. The alternative method is added to calculate the gradient of tidal forcing and SAL directly at the cost of additional multiplications.

When calculating self-attraction and loading, Love numbers are now dimensional when bottom pressure anomaly is used as an input. This change eliminate Love numbers' dependence on mean seawater density. * A new coefficient called linear_scaling is added to SAL CS for the same purpose, although to use bottom pressure anomaly for scalar approximation is not quite justifiable. A WARNING is given when users try to do that. * Two separate field, SSH (sea surface height anomaly) and pbot (total bottom pressure), are used for calculating self attraction and loading when SAL_USE_BPA = False and SAL_USE_BPA = True, respectively. The change is to enhance code readability. --- src/core/MOM_PressureForce_FV.F90 | 36 +++++---- .../lateral/MOM_self_attr_load.F90 | 80 ++++++++++--------- .../lateral/MOM_spherical_harmonics.F90 | 4 +- 3 files changed, 64 insertions(+), 56 deletions(-) diff --git a/src/core/MOM_PressureForce_FV.F90 b/src/core/MOM_PressureForce_FV.F90 index 7a96de15ac..7accb052a5 100644 --- a/src/core/MOM_PressureForce_FV.F90 +++ b/src/core/MOM_PressureForce_FV.F90 @@ -145,7 +145,10 @@ subroutine PressureForce_FV_nonBouss(h, tv, PFu, PFv, G, GV, US, CS, ALE_CSp, p_ ! the pressure anomaly at the top of the layer [R L4 T-4 ~> Pa m2 s-2]. real, dimension(SZI_(G),SZJ_(G)) :: & dp, & !

This bug occurs when TRIM_IC_FOR_P_SURF pressure initialisation is used for ice shelf, whilst in Boussinesq mode and a nonlinear equation of state. The subroutine trim_for_ice calls cut_off_column_top. This routine in Boussinesq mode calls find_depth_of_pressure_in_cell in MOM_density_integrals.F90. This subsequently calls the function frac_dp_at_pos which calls the density equation of state based on given salinity, temperature and depth, which is incorrectly converted into pressure by z position (which is negative) multiplied by g and rho0. The bug results in incorrect densities from the equation of state and therefore an imperfect initialisation of layer thicknesses and sea surface height due to the displacement of water by the ice. The bug is fixed by multiplying the pressure by -1. This commit introduces parameter FRAC_DP_AT_POS_NEGATIVE_P_BUGFIX with default value False to preserve answers. If true, the ice shelf initialisation is accurate to a high degree with a nonlinear equation of state. Answers should not change, except for the added parameter in MOM_parameter_doc. The same functions are called by a unit test in MOM_state_initialization; in this commit I set the MOM_state_initialization unit test to use the existing bug (with a false flag). * Resolve indenting and white space inconsitencies with MOM6 style for ice shelf pressure initialisation bug fix FRAC_DP_AT_POS_NEGATIVE_P_BUGFIX --- src/core/MOM_density_integrals.F90 | 16 +++++++++----- .../MOM_state_initialization.F90 | 21 +++++++++++++------ 2 files changed, 26 insertions(+), 11 deletions(-) diff --git a/src/core/MOM_density_integrals.F90 b/src/core/MOM_density_integrals.F90 index 90994dd073..151bc4ef3c 100644 --- a/src/core/MOM_density_integrals.F90 +++ b/src/core/MOM_density_integrals.F90 @@ -2001,7 +2001,7 @@ end subroutine diagnose_mass_weight_p !> Find the depth at which the reconstructed pressure matches P_tgt subroutine find_depth_of_pressure_in_cell(T_t, T_b, S_t, S_b, z_t, z_b, P_t, P_tgt, & - rho_ref, G_e, EOS, US, P_b, z_out, z_tol) + rho_ref, G_e, EOS, US, P_b, z_out, z_tol, frac_dp_bugfix) real, intent(in) :: T_t !< Potential temperature at the cell top [C ~> degC] real, intent(in) :: T_b !< Potential temperature at the cell bottom [C ~> degC] real, intent(in) :: S_t !< Salinity at the cell top [S ~> ppt] @@ -2020,6 +2020,7 @@ subroutine find_depth_of_pressure_in_cell(T_t, T_b, S_t, S_b, z_t, z_b, P_t, P_t real, intent(out) :: P_b !< Pressure at the bottom of the cell [R L2 T-2 ~> Pa] real, intent(out) :: z_out !< Absolute depth at which anomalous pressure = p_tgt [Z ~> m] real, intent(in) :: z_tol !< The tolerance in finding z_out [Z ~> m] + logical, intent(in) :: frac_dp_bugfix !< If true, use bugfix in frac_dp_at_pos !

This new capability allows for an archaic parameter name to be specified and for appropriate warnings encouraging the user to migrate to using the new name while still setting the parameter as intended, or error messages in the case of inconsistent setting via the archaic name and the correct name. The logging inside of the MOM_parameter_doc files only uses the correct parameter name. Also added the new optional argument set to the 8 read_param routines, to indicate whether a parameter has been found and successfully set. The new set argument is now being used in read_param() calls in obsolete_int(), obsolete_real(), obsolete_char() and obsolete_logical(). Obsolete_logical() in particular was substantially simplified by the use of this new argument, and is now only about half as long as it was. The read_param() set argument is also used in all of the get_param() routines when they are given an old_name argument. The new old_name argument to get_param() is not yet being used in the version of the MOM6 code that is being checked in, but it has been tested extensively by adding or modifying get_param calls in a variant of the initialization code, and it will be used in an updated version of github.com/NOAA-GFDL/MOM6/pull/725 to gracefully handle the deprecation of 4 parameter names. All answers are bitwise identical, but there are new optional arguments to two widely used interfaces. --- src/diagnostics/MOM_obsolete_params.F90 | 37 ++- src/framework/MOM_file_parser.F90 | 288 +++++++++++++++++++++--- 2 files changed, 274 insertions(+), 51 deletions(-) diff --git a/src/diagnostics/MOM_obsolete_params.F90 b/src/diagnostics/MOM_obsolete_params.F90 index a590ae3893..a0401d7199 100644 --- a/src/diagnostics/MOM_obsolete_params.F90 +++ b/src/diagnostics/MOM_obsolete_params.F90 @@ -168,29 +168,15 @@ subroutine obsolete_logical(param_file, varname, warning_val, hint) character(len=*), optional, intent(in) :: hint !< A hint to the user about what to do. !

When Cartesian coordinates are not in use, G%grid_unit_to_L is set to 0. This new element of the grid type is used to test for inconsistent grids or to eliminate rescaling variables in set_rotation_beta_plane(), initialize_velocity_circular(), DOME_initialize_topography(), DOME_initialize_sponges(), DOME_set_OBC_data(), ISOMIP_initialize_topography(), idealized_hurricane_wind_forcing(), Kelvin_set_OBC_data(), Rossby_front_initialize_velocity(), soliton_initialize_thickness(), and soliton_initialize_velocity().

When u and v are used (i.e. the drifters are advected using the resolved velocities only, with no sub-grd component), the particles package needs the layer thickness that is consistent with these velocities, so particles_run needs to be called before any subgrid scale parameterizations are applied. This was not implemented correctly in my last PR, and is corrected here. The particles package also needs the correct timestep for particle advection.

The dimensionally rescaled equivalent element G%Rad_Earth_L is extensively used, and it will continue to exist. G%Rad_Earth_L was introduced in November 27, 2021 as a dimensionally rescaled version of G%Rad_Earth, while the unscaled version was retained because at the time, the Rad_Earth element of the dyn_horgrid_type is also used in SIS2. However, SIS2 has not used G%Rad_Earth since December 23, 2021, so after 3 years we can now safely remove this unused element. Any cases on other branches that might be impacted by this change will not compile.

In the previous version of MOM_open_boundary.F90, a different set of tidal parameters can be set for open boundary tidal forcing, leading to potential inconsistency with astronomical tidal forcing. This commit obsoletes those for open boundary tidal forcing. 3. Another important bug fix is that the equilibrium phase is added to the SAL term, which was missing in the original code. --- src/core/MOM_open_boundary.F90 | 20 +++-- src/diagnostics/MOM_harmonic_analysis.F90 | 26 ++++--- .../lateral/MOM_tidal_forcing.F90 | 77 +++++++++++++++---- 3 files changed, 89 insertions(+), 34 deletions(-) diff --git a/src/core/MOM_open_boundary.F90 b/src/core/MOM_open_boundary.F90 index fb833189ec..797f60bd9b 100644 --- a/src/core/MOM_open_boundary.F90 +++ b/src/core/MOM_open_boundary.F90 @@ -1169,26 +1169,30 @@ subroutine initialize_obc_tides(OBC, US, param_file) type(astro_longitudes) :: nodal_longitudes !< Solar and lunar longitudes for tidal forcing type(time_type) :: nodal_time !< Model time to calculate nodal modulation for. integer :: c !< Index to tidal constituent. + logical :: tides !< True if astronomical tides are also used. call get_param(param_file, mdl, "OBC_TIDE_CONSTITUENTS", tide_constituent_str, & "Names of tidal constituents being added to the open boundaries.", & fail_if_missing=.true.) - call get_param(param_file, mdl, "OBC_TIDE_ADD_EQ_PHASE", OBC%add_eq_phase, & + call get_param(param_file, mdl, "TIDES", tides, & + "If true, apply tidal momentum forcing.", default=.false., do_not_log=.true.) + + call get_param(param_file, mdl, "TIDE_USE_EQ_PHASE", OBC%add_eq_phase, & "If true, add the equilibrium phase argument to the specified tidal phases.", & - default=.false., fail_if_missing=.false.) + old_name="OBC_TIDE_ADD_EQ_PHASE", default=.false., do_not_log=tides) - call get_param(param_file, mdl, "OBC_TIDE_ADD_NODAL", OBC%add_nodal_terms, & + call get_param(param_file, mdl, "TIDE_ADD_NODAL", OBC%add_nodal_terms, & "If true, include 18.6 year nodal modulation in the boundary tidal forcing.", & - default=.false.) + old_name="OBC_TIDE_ADD_NODAL", default=.false., do_not_log=tides) - call get_param(param_file, mdl, "OBC_TIDE_REF_DATE", tide_ref_date, & + call get_param(param_file, mdl, "TIDE_REF_DATE", tide_ref_date, & "Reference date to use for tidal calculations and equilibrium phase.", & - fail_if_missing=.true.) + old_name="OBC_TIDE_REF_DATE", defaults=(/0, 0, 0/), do_not_log=tides) - call get_param(param_file, mdl, "OBC_TIDE_NODAL_REF_DATE", nodal_ref_date, & + call get_param(param_file, mdl, "TIDE_NODAL_REF_DATE", nodal_ref_date, & "Fixed reference date to use for nodal modulation of boundary tides.", & - fail_if_missing=.false., defaults=(/0, 0, 0/)) + old_name="OBC_TIDE_NODAL_REF_DATE", defaults=(/0, 0, 0/), do_not_log=tides) if (.not.

Instead, multiple filters with tidal or arbitrary frequencies as their target frequencies can be turned on. The filter names are specified in MOM_input and must consist of two letters/numbers. If the name of a filter is the same as the name of a tidal constituent, then the corresponding tidal frequency will be used as its target frequency. Otherwise, the user must specify the target frequency by "FILTER_${FILTER_NAME}_OMEGA" in MOM_input. The restarting capability has also been implemented.

By Chengzhu Xu (chengzhu.xu@oregonstate.edu) and Edward D. Zaron +!! +!! The algorithm detects the instantaneous, narrowband tidal signals (u1) from the broadband +!! model output (u) by solving a set of coupled ODEs (the filter equations) at each time step. +!! In the filter equations, u1 is approximately the part of the signal that oscillates at the +!! filter's target frequency, and s1 is approximately the imaginary complement in time of u1. +!! +!! Major revision on Dec 9, 2024: The filters are no longer hard-coded. Instead, multiple filters +!! with tidal frequencies or arbitrary frequencies as their target frequencies can be turned on. +!! The filter names are specified in MOM_input and must consist of two letters/numbers. If the +!! name of a filter is the same as the name of a tidal constituent, then the corresponding tidal +!! frequency will be used as its target frequency. Otherwise, the user must specify the target +!! frequency. In either case, the target frequency is specified by "FILTER_${FILTER_NAME}_OMEGA". !! -!! This module detects instantaneous tidal signals in the model output using a set of coupled ODEs (the filter -!! equations), given the target frequency (om) and the bandwidth parameter (a) of the filter. At each timestep, -!! the filter takes model output (u) as the input and returns a time series consisting of sinusoidal motions (u1) -!! near its target frequency. The filtered tidal signals can be used to parameterize frequency-dependent drag, or -!! to detide the model output. See Xu & Zaron (2024) for detail. +!! The restarting capability has also been implemented. Because the filtering is a point-wise +!! operation, all variables are considered as fields, even if they are velocity components. !! -!!

Comments were also added to explain what the code does when both tmp_scale and unscale arguments are provided, which effectively acts as to allow for changes in the rescaled units. Global_area_integral() and global_mass_integral() were also similarly refactored, but with the added difference that when a tmp_scale argument is provided, the areas or masses in the integrals have units of [L2 A ~> m2 a] or [R Z L2 A ~> kg a] instead of the mixed units of [m2 A ~> m2 a] or [kg A ~> kg a]. As a result the code surrounding the 4 instances where global_area_integral or global_mass_integral were being called with tmp_scale arguments (in MOM.F90 and MOM_ice_shelf.F90) also had to be modified in this same commit. When the optional var argument is absent from a call to global_mass_integral() so that it is the mass itself that is returned, the values (if any) of scale, unscale and tmp_scale are ignored, but the presence of tmp_scale determines whether the mass is returned in [R Z L2 ~> kg] or [kg], consistent with the behavior that would have been obtained if var had been an array of nondimensional 1s. This commit also includes a rescaling in the units of the areaT_global and IareaT_global elements of the ocean_grid_type and dyn_horgrid_type to [L2 ~> m2] and [L-2 ~> m-2], respectively. Although the dyn_horgrid_type is shared between MOM6 and SIS2, these elements are not used in SIS2. A total of 12 rescaling factors were eliminated or moved into unscale arguments as a result of these changes. All answers are bitwise identical, but there are changes in the rescaled units of two elements each in two transparent types, and changes to the rescaling behavior of two publicly visible routines when they are called with tmp_scale arguments. --- src/core/MOM.F90 | 2 +- src/core/MOM_grid.F90 | 6 +- src/diagnostics/MOM_spatial_means.F90 | 398 +++++++++++------- src/framework/MOM_dyn_horgrid.F90 | 6 +- src/ice_shelf/MOM_ice_shelf.F90 | 6 +- .../MOM_shared_initialization.F90 | 2 +- 6 files changed, 259 insertions(+), 161 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 8cfab91cfc..ad906fbdb4 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -4161,7 +4161,7 @@ subroutine get_ocean_stocks(CS, mass, heat, salt, on_PE_only) if (present(mass)) & mass = global_mass_integral(CS%h, CS%G, CS%GV, on_PE_only=on_PE_only) if (present(heat)) & - heat = CS%US%Q_to_J_kg*CS%tv%C_p * & + heat = CS%US%Q_to_J_kg*CS%US%RZL2_to_kg * CS%tv%C_p * & global_mass_integral(CS%h, CS%G, CS%GV, CS%tv%T, on_PE_only=on_PE_only, tmp_scale=CS%US%C_to_degC) if (present(salt)) & salt = 1.0e-3 * global_mass_integral(CS%h, CS%G, CS%GV, CS%tv%S, on_PE_only=on_PE_only, unscale=CS%US%S_to_ppt) diff --git a/src/core/MOM_grid.F90 b/src/core/MOM_grid.F90 index 10335de0a6..e0d456f9a3 100644 --- a/src/core/MOM_grid.F90 +++ b/src/core/MOM_grid.F90 @@ -177,9 +177,9 @@ module MOM_grid df_dx, & !< Derivative d/dx f (Coriolis parameter) at h-points [T-1 L-1 ~> s-1 m-1]. df_dy !< Derivative d/dy f (Coriolis parameter) at h-points [T-1 L-1 ~> s-1 m-1]. - !

Also added the corresponding conversion arguments to the register_scalar_field calls for each of these diagnostics, so that the documented units and conversion factors can be used to confirm the correctness of the documented units for these variables. The internal variables used for the integrated or averaged heat, mass or salt fluxes were also separated for clarity about the units of these variables. All answers and diagnostics are bitwise identical. --- src/core/MOM_forcing_type.F90 | 352 ++++++++++++++++++---------------- 1 file changed, 183 insertions(+), 169 deletions(-) diff --git a/src/core/MOM_forcing_type.F90 b/src/core/MOM_forcing_type.F90 index 998713d1f1..494e36e966 100644 --- a/src/core/MOM_forcing_type.F90 +++ b/src/core/MOM_forcing_type.F90 @@ -296,7 +296,7 @@ module MOM_forcing_type end type mech_forcing !> Structure that defines the id handles for the forcing type -type, public :: forcing_diags +type, public :: forcing_diags ; private !>@{ Forcing diagnostic handles ! mass flux diagnostic handles @@ -1485,15 +1485,15 @@ subroutine register_forcing_type_diags(Time, diag, US, use_temperature, handles, handles%id_taux = register_diag_field('ocean_model', 'taux', diag%axesCu1, Time, & -

This involved changing the scale arguments to global_area_integral to tmp_scale arguments in 8 places so that the units of the output retain the scaling of the input variable. The multiplication by the reverse of the scaling factor was also added to 4 debugging output messages. The documented units of internal wave energies in 5 register_restart_field calls were previously given as "m3 s-2" in non-Boussinesq mode and "J m-2" in Boussinesq mode when the reverse was actually true. This has now been corrected. Also replaced the scale argument to 35 chksum calls with the equivalent but preferred unscale argument, following the pattern elsewhere in the MOM6 code. All answers are bitwise identical, and only debugging code was modified. --- src/parameterizations/lateral/MOM_MEKE.F90 | 2 +- .../lateral/MOM_internal_tides.F90 | 108 ++++++++---------- .../vertical/MOM_set_diffusivity.F90 | 22 ++-- 3 files changed, 61 insertions(+), 71 deletions(-) diff --git a/src/parameterizations/lateral/MOM_MEKE.F90 b/src/parameterizations/lateral/MOM_MEKE.F90 index 1b4ca8f1cd..f6202e22ef 100644 --- a/src/parameterizations/lateral/MOM_MEKE.F90 +++ b/src/parameterizations/lateral/MOM_MEKE.F90 @@ -272,7 +272,7 @@ subroutine step_forward_MEKE(MEKE, h, SN_u, SN_v, visc, dt, G, GV, US, CS, hu, h if (allocated(MEKE%mom_src)) & call hchksum(MEKE%mom_src, 'MEKE mom_src', G%HI, unscale=US%RZ3_T3_to_W_m2*US%L_to_Z**2) if (allocated(MEKE%mom_src_bh)) & - call hchksum(MEKE%mom_src_bh, 'MEKE mom_src_bh', G%HI, scale=US%RZ3_T3_to_W_m2*US%L_to_Z**2) + call hchksum(MEKE%mom_src_bh, 'MEKE mom_src_bh', G%HI, unscale=US%RZ3_T3_to_W_m2*US%L_to_Z**2) if (allocated(MEKE%GME_snk)) & call hchksum(MEKE%GME_snk, 'MEKE GME_snk', G%HI, unscale=US%RZ3_T3_to_W_m2*US%L_to_Z**2) if (allocated(MEKE%GM_src)) & diff --git a/src/parameterizations/lateral/MOM_internal_tides.F90 b/src/parameterizations/lateral/MOM_internal_tides.F90 index 65e9bf55f1..07b00b8b62 100644 --- a/src/parameterizations/lateral/MOM_internal_tides.F90 +++ b/src/parameterizations/lateral/MOM_internal_tides.F90 @@ -147,7 +147,7 @@ module MOM_internal_tides !! vertical profile squared, for each mode [H T-2 ~> m s-2 or kg m-2 s-2] real :: q_itides !< fraction of local dissipation [nondim] real :: mixing_effic !< mixing efficiency [nondim] - real :: En_sum !< global sum of energy for use in debugging, in MKS units [H Z2 T-2 L2 ~> m5 s-2 or J] + real :: En_sum !< global sum of energy for use in debugging, in MKS units [m5 s-2 or J] real :: En_underflow !< A minuscule amount of energy [H Z2 T-2 ~> m3 s-2 or J m-2] integer :: En_restart_power !< A power factor of 2 by which to multiply the energy in restart [nondim] type(time_type), pointer :: Time => NULL() !< A pointer to the model's clock. @@ -331,12 +331,8 @@ subroutine propagate_int_tide(h, tv, Nb, Rho_bot, dt, G, GV, US, inttide_input_C real :: En_sumtmp !

Some compilers seemed to let this through, but it raised a double-deallocation error in GCC. I'm guessing it's because the rotation was implicitly allocating to a new array which was automatically deallocated. But I did not confirm this. This was modified to rotate onto a new array of the same size. The `idim` and `jdim` are passed to `CT_set_data`, which (hopefully) sorts out the indexing. --- src/framework/MOM_coupler_types.F90 | 19 ++++++++++++------- 1 file changed, 12 insertions(+), 7 deletions(-) diff --git a/src/framework/MOM_coupler_types.F90 b/src/framework/MOM_coupler_types.F90 index b931a2ddd2..b76912beb6 100644 --- a/src/framework/MOM_coupler_types.F90 +++ b/src/framework/MOM_coupler_types.F90 @@ -453,14 +453,12 @@ subroutine set_coupler_type_data(array_in, bc_index, var, solubility, scale_fact ! as array_in [A] integer :: subfield !

A total of 4 rescaling variables were moved into unscale arguments, and a block of code that restores the scaling of the output variables was eliminated. The comments describing the units of several variables in this module were made more explicit. The two temporary arrays that store un-summed contributions to the transforms were also moved out of the control structure and made into local variables in the spherical_harmonics_forward routine to allow for the reuse of that memory.

From 93227b3398b9fdb41ec36cd3137d4afc03414b4b Mon Sep 17 00:00:00 2001 From: Robert Hallberg Date: Sun, 5 Jan 2025 06:04:10 -0500 Subject: [PATCH 1280/1329] Rescale 7 ice shelf variables Changed the rescaling of 7 ice shelf variables to cancel out common conversion factors that appear in several expressions. The C_basal_friction argument to initialize_ice_C_basal_friction is now in partially rescaled units, reflecting the portion that does not cancel out fractional-power units from a power law fit with an arbitrary power. The C_basal_friction array in ice_shelf_dyn_CS and the C_friction variable in initialize_ice_C_basal_friction were similarly rescaled. There are new scale factors in a get_param_call and a MOM_read_data call and a conversion factor in register_restart_field call that reflect these changes. The KE_tot and mass_tot variables in write_ice_shelf_energy, are kept in scaled units until they are written. The internal variable fN in calc_shelf_taub is kept in scaled units, but there is now a scaling factor of US%L_to_N in the expression for fB. This latter could be folded into the CF_Max element of ice_shelf_dyn_CS, but I am unsure whether this would be physically sensible. All answers should be bitwise identical and no output should change, but this has not been extensively tested yet. --- src/ice_shelf/MOM_ice_shelf_dynamics.F90 | 40 ++++++++++------------ src/ice_shelf/MOM_ice_shelf_initialize.F90 | 10 +++--- 2 files changed, 25 insertions(+), 25 deletions(-) diff --git a/src/ice_shelf/MOM_ice_shelf_dynamics.F90 b/src/ice_shelf/MOM_ice_shelf_dynamics.F90 index 09eea05127..9f50a77881 100644 --- a/src/ice_shelf/MOM_ice_shelf_dynamics.F90 +++ b/src/ice_shelf/MOM_ice_shelf_dynamics.F90 @@ -111,7 +111,7 @@ module MOM_ice_shelf_dynamics !! of "linearized" basal stress (Pa) [R Z L2 T-1 ~> kg s-1] !!

The units of fluxes%BBL_tidal_dis are [R Z L2 T-3 ~> W m-2], whereas those of fluxes%TKE_tidal were [R Z3 T-3 ~> W m-2]. The factor rescaling between the units of mean kinetic energy and those of turbulent kinetic energy were already in set_diffusivity_CS%BBL_effic, and these have been cancelled out by this change, but this is offset by the addition of rescaling factors in the term setting this array in the NUOPC and mct convert_IOB_to_fluxes routines. In the FMS_cap version of convert_IOB_to_fluxes, the extra rescaling factor is rolled into the scaling factor used in the get_param call for rho_TKE_tidal.

Because this was omitted when ePBL_BBL_column() was first added, a separate runtime parameter, EPBL_BBL_TIDAL_EFFIC, is used to determine the extent to which this tidal energy source is used. The default for EPBL_BBL_TIDAL_EFFIC is currently set to 0 to avoid changing answers, but perhaps it should be changed follow the value of EPBL_BBL_EFFIC. By default all answers are bitwise identical, but there is a new runtime parameter in the MOM_parameter_doc files for cases that use ePBL. --- .../vertical/MOM_energetic_PBL.F90 | 54 +++++++++++++------ 1 file changed, 37 insertions(+), 17 deletions(-) diff --git a/src/parameterizations/vertical/MOM_energetic_PBL.F90 b/src/parameterizations/vertical/MOM_energetic_PBL.F90 index fdbd9c13f0..6e3cdfa1a5 100644 --- a/src/parameterizations/vertical/MOM_energetic_PBL.F90 +++ b/src/parameterizations/vertical/MOM_energetic_PBL.F90 @@ -162,9 +162,14 @@ module MOM_energetic_PBL real :: Max_Enhance_M = 5. !< The maximum allowed LT enhancement to the mixing [nondim]. !/ Bottom boundary layer mixing related options - real :: ePBL_BBL_effic !< The efficiency of bottom boundary layer mixing via ePBL, times + real :: ePBL_BBL_effic !< The efficiency of bottom boundary layer mixing via ePBL driven by + !! the bottom drag dissipation of mean kinetic energy, times !! conversion factors between the natural units of mean kinetic energy - !! and those those used for TKE [Z2 L-2 ~> nondim]. + !! and those used for TKE [Z2 L-2 ~> nondim]. + real :: ePBL_tidal_effic !< The efficiency of bottom boundary layer mixing via ePBL driven by + !! the bottom drag dissipation of tides, times conversion factors + !! between the natural units of mean kinetic energy and those used for + !!

This was compensated for by multiplication by factors of the square root of the drag coefficient in add_drag_diffusivity and add_LOTW_BBL_diffusivity, but when an equivalent expression was added in the ePBL BBL code this was erroneously omitted. Moreover, Alistair has had a comment questioning this added factor in add_LOTW_BBL_diffusivity for a decade without adequate resolution. To correct this confusing situation, visc%BBL_meanKE_loss has been changed to include the missing factor of the square root of the drag coefficient, while the new variable visc%BBL_meanKE_loss_sqrtCd was added to allow for the previous answers to be recovered when the new runtime parameter EPBL_BBL_EFFIC_BUG is set to true and DRAG_DIFFUSIVITY_ANSWER_DATE is set below 20250302. Because the ePBL bottom boundary layer was only added to dev/gfdl a month ago and has not yet been merged into main, we can be confident that it has only received very limited use as yet, so the default for EPBL_BBL_EFFIC_BUG is false but this default will change answers when EPBL_BBL_EFFIC > 0. The default for DRAG_DIFFUSIVITY_ANSWER_DATE is 20250101, which will preserve the previous answers, but the default should later be taken from DEFAULT_ANSWER_DATE. By default, answers are unchanged in any cases that are more than a month old, but answers can change by default in a few very recent experiments. There are two new runtime parameters in some MOM_parameter_doc files. --- src/core/MOM_variables.F90 | 3 ++ .../vertical/MOM_energetic_PBL.F90 | 13 ++++++- .../vertical/MOM_set_diffusivity.F90 | 38 ++++++++++++++++--- .../vertical/MOM_set_viscosity.F90 | 2 + 4 files changed, 49 insertions(+), 7 deletions(-) diff --git a/src/core/MOM_variables.F90 b/src/core/MOM_variables.F90 index efd558cdb3..cabda1cf58 100644 --- a/src/core/MOM_variables.F90 +++ b/src/core/MOM_variables.F90 @@ -239,6 +239,9 @@ module MOM_variables !! h points [H T-1 ~> m s-1 or kg m-2 s-1].

GV%g_Earth_Z_T2 is more convenient for single-column energy calculations, but the two will only differ by an integer power of two when dimensional rescaling is applied.

These changes included using GV%g_Earth_Z_T2 instead of GV%g_Earth in 16 places that contribute to potential energy calculations. In 5 lines, the unit scaling factors were eliminated, while in 2 others the rescaling factors were revised. In addition, the rescaling factors to go from the units of mean kinetic energy to those of turbulent kinetic energy were folded into the internal representation of the bulk Richardson numbers. The units in comments describing 58 variables and the conversion arguments for 10 diagnostics were updated accordingly. All answers and output are bitwise identical. --- .../vertical/MOM_bulk_mixed_layer.F90 | 204 +++++++++--------- 1 file changed, 103 insertions(+), 101 deletions(-) diff --git a/src/parameterizations/vertical/MOM_bulk_mixed_layer.F90 b/src/parameterizations/vertical/MOM_bulk_mixed_layer.F90 index 3efbfdd300..d9d9cf6b14 100644 --- a/src/parameterizations/vertical/MOM_bulk_mixed_layer.F90 +++ b/src/parameterizations/vertical/MOM_bulk_mixed_layer.F90 @@ -46,16 +46,18 @@ module MOM_bulk_mixed_layer !! ocean, instead of passing through to the bottom mud. real :: TKE_decay !< The ratio of the natural Ekman depth to the TKE !! decay scale [nondim]. - real :: bulk_Ri_ML !< The efficiency with which mean kinetic energy - !! released by mechanically forced entrainment of - !! the mixed layer is converted to TKE [nondim]. - real :: bulk_Ri_convective !< The efficiency with which convectively - !! released mean kinetic energy becomes TKE [nondim]. + real :: bulk_Ri_ML !< The efficiency with which mean kinetic energy released by + !! mechanically forced entrainment of the mixed layer is + !! converted to TKE, times conversion factors between the + !! natural units of mean kinetic energy and TKE [Z2 L-2 ~> nondim] + real :: bulk_Ri_convective !< The efficiency with which convectively released mean kinetic + !! energy becomes TKE, times conversion factors between the natural + !! units of mean kinetic energy and TKE [Z2 L-2 ~> nondim] real :: vonKar !< The von Karman constant as used for mixed layer viscosity [nondim] real :: Hmix_min !< The minimum mixed layer thickness [H ~> m or kg m-2]. real :: mech_TKE_floor !< A tiny floor on the amount of turbulent kinetic energy that is !! used when the mixed layer does not yet contain HMIX_MIN fluid - !!

Previously the advection and diabatic codes were seperated but called with the same timestep. If DT_TADVECT is not specified, then DT_THERM is used. The comments describing DT_THERM and DT_TADVECT have been modified to refelect this change. * Add error warning if diabatic_first is true Currently, this option is not intended to be used if diabatic_first is true, so a fatal error flag has been added. This will be addressed in a future pull request. * Change variable, add do advection before thermo step Change DT_TADVECT to DT_TRACER_ADVECT to be clearer. dt_tadvect has been changed to dt_tr_adv and tadvect_spans_coupling to tradv_spans_coupling. An additional check has been added before the advection step. If thermo_spans_coupling is true, do_advection is true if t_dyn_rel_thermo is ~DT_THERM so that the thermodynamics step would happen at the next possible time. This ensures that the thermodynamics step is not prevented because advection has not been resolved. * Add logic to do_diabatic check The do_diabatic check should only be done if do_thermo is true. This is relevant when do_dyn or do_thermo are being used from outside step_MOM to order the updates of the thermodynamics and dynamics, such as when the interspesed coupling is used. * Initialize do_diabatic * Change TRADV_SPANS_COUPLING default Change the default for TRADV_SPANS_COUPLING to be the same as THERMO_SPANS_COUPLING, which is read first, instead of false.

These involved adding optional conversion arguments to register_field_infra and register_field_nc, which are then stored in a new element in the MOM_field type, and use the conversion factors to unscale variables before they are written in the ten write_field routines in MOM_io_file. The new optional arguments to register_field are used in MOM_create_file, taking their values from the vardesc types sent to this routine. This commit also alters modify_vardesc to store the value of the conversion optional argument in the conversion element of the vardesc type. Also modified query_vardesc so that the conversion factor is returned via the conversion optional argument. These steps had been intended when these optional arguments were first added, but for some reason they had not actually been used. The conversion values stored in a vardesc type are also now used in the register_diag_field call in ocean_register_diag. However, it does not appear that ocean_register_diag is actually used anymore, so it might be a candidate for deletion.

Their units are also documented in the same calls, so this is now analogous to what is done the register_diag_field calls for diagnostics that are handled by the MOM_diag_mediator. All calculations in write_energy and almost all internal variables are now in rescaled units.

Several internal turns variables in the same routines were renamed qturns to allow for the new optional arguments. Also check for whether the MOM_domain%domain_in pointer is associated before it is used, avoiding a segmentation fault that was occurring when a restart file is read and ROTATE_INDEX is true. Also added rotate_array calls to ensure that the halo values are retained while reading data into a rotated array. These changes are necessary to allow for the model to be initialized from a restart files with rotated grids. Several instances of continuation line indentation that do not follow the typical 4-space pattern used elsewhere in the MOM6 code and documented in the MOM6 style guide were also altered to follow the standard. All answers that previously worked are bitwise identical, but there are new optional arguments to publicly visible interfaces. --- src/framework/MOM_io.F90 | 264 ++++++++++++++++++++++++--------------- 1 file changed, 163 insertions(+), 101 deletions(-) diff --git a/src/framework/MOM_io.F90 b/src/framework/MOM_io.F90 index 895efecbd6..9177017c30 100644 --- a/src/framework/MOM_io.F90 +++ b/src/framework/MOM_io.F90 @@ -2131,9 +2131,8 @@ subroutine MOM_read_data_0d(filename, fieldname, data, timelevel, scale, MOM_Dom !! as 4d arrays in the file. call read_field(filename, fieldname, data, & - timelevel=timelevel, scale=scale, MOM_Domain=MOM_Domain, & - global_file=global_file, file_may_be_4d=file_may_be_4d & - ) + timelevel=timelevel, scale=scale, MOM_Domain=MOM_Domain, & + global_file=global_file, file_may_be_4d=file_may_be_4d) end subroutine MOM_read_data_0d @@ -2164,9 +2163,9 @@ subroutine MOM_read_data_1d(filename, fieldname, data, timelevel, scale, MOM_Dom !! as 4d arrays in the file. call read_field(filename, fieldname, data, & - timelevel=timelevel, scale=scale, MOM_Domain=MOM_Domain, & - global_file=global_file, file_may_be_4d=file_may_be_4d & - ) + timelevel=timelevel, scale=scale, MOM_Domain=MOM_Domain, & + global_file=global_file, file_may_be_4d=file_may_be_4d) + end subroutine MOM_read_data_1d @@ -2182,12 +2181,13 @@ end subroutine MOM_read_data_1d_int !> Read a 2d array from file using infrastructure I/O. -subroutine MOM_read_data_2d(filename, fieldname, data, MOM_Domain, & - timelevel, position, scale, global_file, file_may_be_4d) +subroutine MOM_read_data_2d(filename, fieldname, data, MOM_Domain, timelevel, position, & + scale, global_file, file_may_be_4d, turns) character(len=*), intent(in) :: filename !< Input filename character(len=*), intent(in) :: fieldname !< Field variable name real, dimension(:,:), intent(inout) :: data !< Field value in arbitrary units [A ~> a] - type(MOM_domain_type), intent(in) :: MOM_Domain !< Model domain decomposition + type(MOM_domain_type), target, & + intent(in) :: MOM_Domain !< Model domain decomposition integer, optional, intent(in) :: timelevel !< Time level to read in file integer, optional, intent(in) :: position !< Grid positioning flag real, optional, intent(in) :: scale !< A scaling factor that the variable is multiplied by @@ -2196,31 +2196,39 @@ subroutine MOM_read_data_2d(filename, fieldname, data, MOM_Domain, & logical, optional, intent(in) :: global_file !< If true, read from a single file logical, optional, intent(in) :: file_may_be_4d !< If true, fields may be stored !! as 4d arrays in the file. + integer, optional, intent(in) :: turns !< Number of quarter-turns to rotate the data.

Also added runtime options to convert negative zeros into ordinary zeros before they are written to restart files (selected with RESTART_UNSIGNED_ZEROS) and to properly do the checksums on the velocity points on all of the faces (selected with RESTART_SYMMETRIC_CHECKSUMS). Also added the new interfaces copy_restart_var and copy_restart vector to use the names of restart variables and the pointers stored in the restart control structure to obtain a copy of the variables as the restart variables with the option to undo the rotation. These routines are necessary because the reading of restart files occurs during a phase of the model initialization that works on an unrotated grid, and they are called from inside of MOM_initialize_state. The ranges for the checksums are now set correctly for each variable, depending on where it is discretized, but when RESTART_SYMMETRIC_CHECKSUMS is false, the previous ranges are still used so answers do not change in unrotated test case. The conversion factors used for the pair of register_restart_field calls in register_restart_pair now include the necessary sign changes for the rotation, as set in the new internal routine set_conversion_pair. There is also now a scalar_pair optional argument to the register_restart_pair routines to accommodate the rotation of pairs of scalars that do not change sign when rotated (e.g., grid-lengths). Instead of working with the hor_grid character string, the restart code has been modified to instead use the encoded integer position argument returned from query_vardesc. This avoids several redundant blocks of code that translate the hor_grid strings into positions. All answers are bitwise identical when there is no grid rotation, but with grid rotation the restart files that are created are modified to have the correct signs and replicate the restart fields with no rotation. Also, cases with grid rotation can now be reinitialized from restart files, while previously this simply did not work, either giving an incorrect reinitialized state or a segmentation fault.

If true, then the `MASS_WEIGHT_IN_PRESSURE_GRADIENT` and `MASS_WEIGHT_IN_PRESSURE_GRADIENT_TOP` effect of weighting T/S integrals in slanted grid cell FV PGF calculation is turned off if both sides of the grid cell are nonvanished, where nonvanished means thickness greater than `RESET_INTXPA_H_NONVANISHED` which defaults to 1e-6 m. Since the benefit of `MASS_WEIGHT_IN_PRESSURE_GRADIENT` happens in vanished layers (creating a fake PGF away from vanished layer, which is arrested by upwinded viscosity) the benefit is still there, but now we can use `MASS_WEIGHT_IN_PRESSURE_GRADIENT` for coordinates that also have slanted layers in the open ocean that are not vanished, e.g. sigma coordinates or SIGMA_SHELF_ZSTAR coordinates in the ice shelf where we DO trust T and S values. Additionally, this is required near a grounding line in a 3D z-coord ice shelf as some strange looking slanted non-vanished cells can emerge, and MWIPG being on would create fake PGFs in non-vanished cells (and therefore generating spurious currents). Reccommend `MASS_WEIGHT_IN_PGF_VANISHED_ONLY` to be set to True, as well as `MASS_WEIGHT_IN_PRESSURE_GRADIENT` and `MASS_WEIGHT_IN_PRESSURE_GRADIENT_TOP` if you have vanishing layers with min thickness < 0.1m. Also modifies MassWt_u and MassWt_v diagnostics to reflect usage of MASS_WEIGHT_IN_PRESSURE_GRADIENT. This commit should not change answers since it defaults to False. However, my implementation is not very efficient and should probably be optimised. * Minor style updates to previous commit of Add MASS_WEIGHT_IN_PGF_VANISHED_ONLY to modify mass weighting * Address comments from Bob by adding scaling to dimensional numbers, replacing Boussinesq rho in nonBoussinesq code, and removing white space to follow 2-space indenting. --- src/core/MOM_PressureForce_FV.F90 | 32 ++++- src/core/MOM_density_integrals.F90 | 197 +++++++++++++++++++++++++++-- 2 files changed, 211 insertions(+), 18 deletions(-) diff --git a/src/core/MOM_PressureForce_FV.F90 b/src/core/MOM_PressureForce_FV.F90 index cccfa1c2e4..01ed666f77 100644 --- a/src/core/MOM_PressureForce_FV.F90 +++ b/src/core/MOM_PressureForce_FV.F90 @@ -59,6 +59,7 @@ module MOM_PressureForce_FV logical :: reset_intxpa_integral !< If true and the surface displacement between adjacent cells !! exceeds the vertical grid spacing, reset intxpa at the interface below !! a trusted interior cell.

Eliminated the internal routine propagate_corner_spread. This routine was never completely implemented, and it has never been used in any realistic configurations. In particular, it appears that it will only work on a Cartesian grid in which the position variables (G%geoLonBu and G%geoLatBu) have the same units as G%dx. The comment describing propagate_corner_spread() indicates that "it is too numerically diffusive to be of much use as of yet" and that "it is not yet compatible with reflection schemes", so we have no plans to complete its implementation. Although it is being deleted, it can always be recovered from older branches of MOM6. 2. The runtime parameter INTERNAL_TIDE_CORNER_ADVECT, which triggered the use of propagate_corner_spread was obsoleted. 3. Started adding the option to alternate the direction of the internal tide propagation. The code that actually enacts the change is still commented out to avoid changing answers, but it could readily be enabled later with changes to a single line, and all the required code is present. 4. The units of 9 area-integrated energy budget debugging diagnostics were corrected, as is rescaling factor when their sum is written to stdout. With these changes, all answers are expected to be bitwise identical in any cases that are in active use, but an under-used runtime option has been eliminated from some MOM_parameter_doc files. --- src/diagnostics/MOM_obsolete_params.F90 | 1 + .../lateral/MOM_internal_tides.F90 | 490 ++++-------------- 2 files changed, 91 insertions(+), 400 deletions(-) diff --git a/src/diagnostics/MOM_obsolete_params.F90 b/src/diagnostics/MOM_obsolete_params.F90 index a0401d7199..f81f2a7574 100644 --- a/src/diagnostics/MOM_obsolete_params.F90 +++ b/src/diagnostics/MOM_obsolete_params.F90 @@ -114,6 +114,7 @@ subroutine find_obsolete_params(param_file) call obsolete_logical(param_file, "SMOOTH_RI", hint="Instead use N_SMOOTH_RI.") + call obsolete_logical(param_file, "INTERNAL_TIDE_CORNER_ADVECT", .false.) call obsolete_logical(param_file, "TIDE_USE_SAL_SCALAR", hint="Use SAL_SCALAR_APPROX instead.") call obsolete_logical(param_file, "TIDAL_SAL_SHT", hint="Use SAL_HARMONICS instead.") call obsolete_int(param_file, "TIDAL_SAL_SHT_DEGREE", hint="Use SAL_HARMONICS_DEGREE instead.") diff --git a/src/parameterizations/lateral/MOM_internal_tides.F90 b/src/parameterizations/lateral/MOM_internal_tides.F90 index ab770f266e..794de22636 100644 --- a/src/parameterizations/lateral/MOM_internal_tides.F90 +++ b/src/parameterizations/lateral/MOM_internal_tides.F90 @@ -106,19 +106,19 @@ module MOM_internal_tides real, allocatable, dimension(:,:,:,:,:) :: TKE_slope_loss !< internal tide energy loss due to the residual at slopes [H Z2 T-3 ~> m3 s-3 or W m-2] real, allocatable, dimension(:,:) :: TKE_input_glo_dt - !< The energy input to the internal waves * dt [H Z2 T-2 ~> m3 s-2 or J m-2]. + !< The integrated energy input to the internal waves [H Z2 L2 T-2 ~> m5 s-2 or J] real, allocatable, dimension(:,:) :: TKE_leak_loss_glo_dt - !< energy lost due to misc background processes * dt [H Z2 T-2 ~> m3 s-2 or J m-2] + !< Integrated energy lost due to misc background processes [H Z2 L2 T-2 ~> m5 s-2 or J] real, allocatable, dimension(:,:) :: TKE_quad_loss_glo_dt - !< energy lost due to quadratic bottom drag * dt [H Z2 T-2 ~> m3 s-2 or J m-2] + !< Integrated energy lost due to quadratic bottom drag [H Z2 L2 T-2 ~> m5 s-2 or J] real, allocatable, dimension(:,:) :: TKE_Froude_loss_glo_dt - !< energy lost due to wave breaking [H Z2 T-2 ~> m3 s-2 or J m-2] + !< Integrated energy lost due to wave breaking [H Z2 L2 T-2 ~> m5 s-2 or J] real, allocatable, dimension(:,:) :: TKE_itidal_loss_glo_dt !< energy lost due to small-scale wave drag [H Z2 T-2 ~> m3 s-2 or J m-2] real, allocatable, dimension(:,:) :: TKE_residual_loss_glo_dt - !< internal tide energy loss due to the residual at slopes [H Z2 T-2 ~> m3 s-2 or J m-2] + !< internal tide energy loss due to the residual at slopes [H Z2 L2 T-2 ~> m5 s-2 or J] real, allocatable, dimension(:,:) :: error_mode - !< internal tide energy budget error for each mode [H Z2 T-2 ~> m3 s-2 or J m-2] + !< internal tide energy budget error for each mode [H Z2 L2 T-2 ~> m5 s-2 or J] real, allocatable, dimension(:,:) :: tot_leak_loss !< Energy loss rates due to misc background processes, !! summed over angle, frequency and mode [H Z2 T-3 ~> m3 s-3 or W m-2] real, allocatable, dimension(:,:) :: tot_quad_loss !< Energy loss rates due to quadratic bottom drag, @@ -182,12 +182,12 @@ module MOM_internal_tides !< The internal wave energy density as a function of (i,j,angle,frequency,mode) !! integrated within an angular and frequency band [H Z2 T-2 ~> m3 s-2 or J m-2] real, allocatable :: En_ini_glo(:,:) - !< The internal wave energy density as a function of (frequency,mode) - !! integrated within an angular and frequency band [H Z2 T-2 ~> m3 s-2 or J m-2] + !< The internal wave energy density as a function of (frequency,mode) spatially + !! integrated within an angular and frequency band [H Z2 L2 T-2 ~> m5 s-2 or J] !! only at the start of the routine (for diags) real, allocatable :: En_end_glo(:,:) - !< The internal wave energy density as a function of (frequency,mode) - !! integrated within an angular and frequency band [H Z2 T-2 ~> m3 s-2 or J m-2] + !< The internal wave energy density as a function of (frequency,mode) spatially + !! integrated within an angular and frequency band [H Z2 L2 T-2 ~> m5 s-2 or J] !! only at the end of the routine (for diags) real, allocatable :: En_restart_mode1(:,:,:,:) !< The internal wave energy density as a function of (i,j,angle,freq) @@ -328,7 +328,7 @@ subroutine propagate_int_tide(h, tv, Nb, Rho_bot, dt, G, GV, US, inttide_input_C real :: en_subRO !

The decription of the subroutine is also updated. * Add runtime parameter SET_DTBT_USE_BT_CONT The runtime parameter allows to use BT_CONT optional input argument in subroutine set_dtbt if BT_CONT type is available. Originally, when BT_CONT is used, set_dtbt is estimated with zero surface height. The eta optinoal input argument has no effect since it only works with NONLINEAR_BT_CONTINUITY is true, which is by default false when BT_CONT is used. The added option allows accurate estimate of dtbt when the mean surface height of the domain is not at the same level, while maintains old answers. Also, an unused field calc_dtbt in type MOM_dyn_split_RK2_CS is removed. * Minor fixes on setting dtbt in barotropic_init * Fix a bug that local variable calc_dtbt is not initialized. * Rename dtbt_tmp to dtbt_restart for clarity * Add a comment about the usage of subroutine call set_dtbt * Remove an unused input argument eta in barotropic_init --- src/core/MOM_barotropic.F90 | 52 ++++++++++++++-------------- src/core/MOM_dynamics_split_RK2.F90 | 18 +++++++--- src/core/MOM_dynamics_split_RK2b.F90 | 18 +++++++--- 3 files changed, 52 insertions(+), 36 deletions(-) diff --git a/src/core/MOM_barotropic.F90 b/src/core/MOM_barotropic.F90 index 9e2014dc81..8ba4b106fd 100644 --- a/src/core/MOM_barotropic.F90 +++ b/src/core/MOM_barotropic.F90 @@ -2847,26 +2847,26 @@ subroutine btstep(U_in, V_in, eta_in, dt, bc_accel_u, bc_accel_v, forces, pbce, end subroutine btstep -!> This subroutine automatically determines an optimal value for dtbt based -!! on some state of the ocean. -subroutine set_dtbt(G, GV, US, CS, eta, pbce, BT_cont, gtot_est, SSH_add) +!> This subroutine automatically determines an optimal value for dtbt based on some state of the ocean.

in recsaled units Revised the calculation of the netFWGlobalAdj, vPrecGlobalAdj and saltFluxGlobalAdj elements of the forcing type to work in dimensionally rescaled units, making use of the unscale argument to reproducing_sum. This change includes the addition of conversion factors to the register_scalar_field calls, and changes to the units of 15 variables to be rescaled. A total of 27 instances of multiplication by unit conversion factors were eliminated as a part of these changes, with 15 other unit conversion factors added via unscale arguments. All answers and output are bitwise identical, but there are changes to the units of three variables in a transparent type. --- .../FMS_cap/MOM_surface_forcing_gfdl.F90 | 52 +++++++++---------- .../STALE_mct_cap/mom_surface_forcing_mct.F90 | 48 ++++++++--------- .../nuopc_cap/mom_surface_forcing_nuopc.F90 | 45 ++++++++-------- src/core/MOM_forcing_type.F90 | 13 ++--- 4 files changed, 79 insertions(+), 79 deletions(-) diff --git a/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 b/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 index f59a7c7fe1..4076575cb6 100644 --- a/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 +++ b/config_src/drivers/FMS_cap/MOM_surface_forcing_gfdl.F90 @@ -67,7 +67,7 @@ module MOM_surface_forcing_gfdl real :: wind_stress_multiplier !< A multiplier applied to incoming wind stress [nondim]. real :: Rho0 !< Boussinesq reference density [R ~> kg m-3] - real :: area_surf = -1.0 !< Total ocean surface area [m2] + real :: area_surf = -1.0 !< Total ocean surface area [L2 ~> m2] real :: latent_heat_fusion !< Latent heat of fusion [Q ~> J kg-1] real :: latent_heat_vapor !< Latent heat of vaporization [Q ~> J kg-1] @@ -242,9 +242,9 @@ subroutine convert_IOB_to_fluxes(IOB, fluxes, index_bounds, Time, valid_time, G, SSS_anom, & !

As a result of these changes, the units of 8 variables were changed to be rescaled, and six instances of multiplication by rescaling factors were changed into unscale arguments. MOM_state_stats() is exercised by setting DEBUG_CONSERVATION = True, and it has been verified that MOM_state_stats() gives results that are invariant to the use of dimensional rescaling. All answers and output are bitwise identical. --- src/core/MOM_checksum_packages.F90 | 35 +++++++++++++++--------------- 1 file changed, 17 insertions(+), 18 deletions(-) diff --git a/src/core/MOM_checksum_packages.F90 b/src/core/MOM_checksum_packages.F90 index 196ac73063..13f71a3f16 100644 --- a/src/core/MOM_checksum_packages.F90 +++ b/src/core/MOM_checksum_packages.F90 @@ -275,13 +275,13 @@ subroutine MOM_state_stats(mesg, u, v, h, Temp, Salt, G, GV, US, allowChange, pe !

This allows internal wave drag to be optimized for different frequency bands independently, without affecting the low-frequency, non-tidal motions. Also fixed the bug that Filt_accum() does not return a valid output if it is called at the corrector step. * Frequency-dependent internal wave drag Minor performance optimization. Also, this commit allows the filters to be activated without the frequency-dependent drag being activated. --- src/core/MOM_barotropic.F90 | 81 +++++++++-- .../lateral/MOM_streaming_filter.F90 | 30 ++-- .../lateral/MOM_wave_drag.F90 | 135 ++++++++++++++++++ 3 files changed, 221 insertions(+), 25 deletions(-) create mode 100644 src/parameterizations/lateral/MOM_wave_drag.F90 diff --git a/src/core/MOM_barotropic.F90 b/src/core/MOM_barotropic.F90 index 8ba4b106fd..ccb49e7036 100644 --- a/src/core/MOM_barotropic.F90 +++ b/src/core/MOM_barotropic.F90 @@ -32,6 +32,7 @@ module MOM_barotropic use MOM_variables, only : BT_cont_type, alloc_bt_cont_type use MOM_verticalGrid, only : verticalGrid_type use MOM_variables, only : accel_diag_ptrs +use MOM_wave_drag, only : wave_drag_init, wave_drag_calc, wave_drag_CS implicit none ; private @@ -251,6 +252,8 @@ module MOM_barotropic !! invariant and linearized. logical :: use_filter !< If true, use streaming band-pass filter to detect the !! instantaneous tidal signals in the simulation. + logical :: linear_freq_drag !< If true, apply a linear frequency-dependent drag to the tidal + !! velocities.

This includes expanding the range of values where the viscosities are calculated to those used in symmetric memory mode when DEBUG is true, even though these are not used for efficiency. One set of vorticity-point loop ranges was also corrected when the recently added parameter EY24_EBT_BS is true to avoid setting an extra unused value, perhaps correcting non-symmetric memory mode cases that would not reproduce across PE count and layout.

However, this requires the addition of other rescaling factors when forces%tau_mag is set from the wind stresses. A total of 40 rescaling factors were eliminated, while another 36 were added, all where the components of the wind stress are used to calculate the magnitude of the wind stress. Several other internal variables were also rescaled analogously for simplicity.

The previous rotated_field_chksum interface has been retained because it is still being used in SIS2, but this may change in the future.

This is the most computationally efficient way to specify a linear EOS, but we are usually linearizing about a reference T and S that are not 0. The new interface is based on TREF, SREF, and RHO_TREF_SREF, where: RHO(T,S) = RHO_TREF_SREF + DRHO_DT*(T-TREF) + DRHO_DS*(S-SREF) RHO_T0_S0 = RHO_TREF_SREF - DRHO_DT*TREF - DRHO_DS*SREF RHO(T,S) = RHO_T0_S0 + DRHO_DT*T + DRHO_DS*S The defaults for TREF and SREF are zero and for RHO_TREF_SREF is 1000.0.

Clean up inputs and local variables in step_MOM_thermo by removing those only used for gid generation and remapping. Routines that need to be done after step_thermo, grid generation and remapping, regardless of use_ALE or not into another routine since they do not make sense in ALE_gridgen_and_remapping. Answers and diagnostics have not changed in Baltic case in ALE mode. Testing still needs to be done layer mode and with particles. * Update Names of routines * Fix doxygen and calltree errors --------- Co-authored-by: Theresa Morrison Co-authored-by: Theresa Morrison --- src/core/MOM.F90 | 367 +++++++++++++++++++++++++++++------------------ 1 file changed, 226 insertions(+), 141 deletions(-) diff --git a/src/core/MOM.F90 b/src/core/MOM.F90 index 8e71cae447..f71944284b 100644 --- a/src/core/MOM.F90 +++ b/src/core/MOM.F90 @@ -472,6 +472,7 @@ module MOM integer :: id_clock_ocean integer :: id_clock_dynamics integer :: id_clock_thermo +integer :: id_clock_remap integer :: id_clock_tracer integer :: id_clock_diabatic integer :: id_clock_adiabatic @@ -880,6 +881,9 @@ subroutine step_MOM(forces_in, fluxes_in, sfc_state, Time_start, time_int_in, CS !

If true, in ocean columns where no non-tilted, non-vanished layer can be found (e.g. near specific shaped ice shelf grounding lines), rather than using the top surface to integrate downwards as the reference, the code finds and chooses the flattest (i.e. minimum difference between depth or pressure) interface as the reference. The parameter defaults to False therefore should not change default answers. However, if true, combined with other ice shelf code changes e.g. MASS_WEIGHT_IN_PGF_VANISHED_ONLY = True, RESET_INTXPA_INTEGRAL = True, MASS_WEIGHT_IN_PRESSURE_GRADIENT = True and MASS_WEIGHT_IN_PRESSURE_GRADIENT_TOP = True + initialisation code fixes I get very low spurious currents in the Boussinesq ZSTAR and SIGMA_SHELF_ZSTAR ISOMIP+ test cases. * Amend RESET_INTXPA_INTEGRAL_FLATTEST description to refer to flattest interface rather than flattest layer. --- src/core/MOM_PressureForce_FV.F90 | 201 ++++++++++++++++++++++++------ 1 file changed, 162 insertions(+), 39 deletions(-) diff --git a/src/core/MOM_PressureForce_FV.F90 b/src/core/MOM_PressureForce_FV.F90 index 871f3558a0..c160d7c7c9 100644 --- a/src/core/MOM_PressureForce_FV.F90 +++ b/src/core/MOM_PressureForce_FV.F90 @@ -61,6 +61,8 @@ module MOM_PressureForce_FV !! exceeds the vertical grid spacing, reset intxpa at the interface below !! a trusted interior cell.

A new warning message cautions about the suspected problems with the internal wave version of the code.

(#846) * Updates MOM_kappa_shear averaging and diagnostics. - Update to horizontal averaging procedure in MOM_kappa_shear for VERTEX_SHEAR = True. - Adds geometric and thickness weighted averages for moving diffusivity from vertices to tracer points. - Adds new diagnostics of N2, S2, Kd, and TKE both with and without VERTEX_SHEAR, useful for debugging. * Shorten two lines in MOM_kappa_shear to comply w/ MOM6 standard * More updates for Kappa_Shear horizontal averaging - Fix OMP directives for new diagnostics - Remove quasi-2d fields that broke OMP threading - Reworking horizontal averaging algorithm. * Initialize new variables to zero in kappa_shear * Only initialize some arrays in kappa shear if they are used * Add VERTEX_SHEAR_GEOMETRIC_MEAN_KDMIN runtime option to Kappa Shear * *+Revise horizontal avg in Calc_kappa_shear_vertex Revised the Calc_kappa_shear_vertex code where it averages the diffusivities at the vertices back to the tracer points when there is either a geometric mean being used or thickness weighting. With these changes, the code should now pass dimensional consistency testing, work properly with openMP threading enabled, and give sensible values of the diffusivity for massless layers. Also corrected the indenting of several recently added lines to follow the MOM6 2-space indenting convention. This commit can change answers slightly in some cases where VERTEX_SHEAR = True, especially if VERTEX_SHEAR_GEOMETRIC_MEAN = True or VERTEX_SHEAR_THICKNESS_MEAN = True. The recently added runtime parameter VERTEX_SHEAR_KD_MEAN_ANSWER_DATE (which has not yet been added to the dev/gfdl branch of the code) was no longer needed and has been eliminated. * Shorten variable name VS_GeometricMean_Kd_min to VS_GeoMean_Kdmin to help with line length issues. --------- Co-authored-by: brandon.reichl Co-authored-by: Robert Hallberg --- .../vertical/MOM_kappa_shear.F90 | 317 +++++++++++++++--- 1 file changed, 277 insertions(+), 40 deletions(-) diff --git a/src/parameterizations/vertical/MOM_kappa_shear.F90 b/src/parameterizations/vertical/MOM_kappa_shear.F90 index b3f8fb4da1..53d6b36e4a 100644 --- a/src/parameterizations/vertical/MOM_kappa_shear.F90 +++ b/src/parameterizations/vertical/MOM_kappa_shear.F90 @@ -90,6 +90,10 @@ module MOM_kappa_shear !! greater than 1.
