INSTRUCTIONS
INSTRUCTIONS:

*) The code can be compiled using ifort or gfortan using 'make cloud_cci'
*) Run the simulator by '.cloud_cci.x namelist_cloud_cci


INPUT:

'CC' = Horizontal fraction of the grid box covered by cloud [0-1]. code=248

'CI' = Sea Ice Cover [0-1]. code=31

'CIWC' = Specific cloud ice water content. Grid-box
mean specific cloud ice water content (mass of condensate
/ mass of moist air). [kg kg**-1]. code=247

'CLWC' = Specific cloud liquid water content. Grid-box mean
specific cloud liquid water content (mass of condensate /
mass of moist air) [kg kg**-1]. code=246

'PSURF'= Surface pressure [(Pa)]. code=1

'Q' = Specific humidity. Grid box mean (mass of water vapour /
mass of moist air). [kg kg**-1]. code=133

'SKT' = Skin temperature. Temperature of the surface skin
(radiative surface temperature). Before 01/10/2008, the skin
temperature was equal to the bulk SST over the
ocean. [K]. code=235

'T' = Temperature [K]. code=130

'T2M' = 2 metre temperature [K]. code=167

'TCC' = Total cloud cover. Total cloud cover derived from model
levels using the model's overlap assumption [0-1]. code=164

'TCWV' = Total column water vapour (Vertically integrated water
vapour) [kg m**-2]. code=137

OUTPUT:

cer_ice = simulated ice effective radius
cer_liq = simulated liquid effective radiusd
cfc = simulated total cloud cover
cfc_low = simulated total cloud cover for clouds with CTP greater than 680 hPa
cfc_mid = simulated total cloud cover for clouds with CTP less than 680 hPa and greater than 440 hPa
cfc_high = simulated total cloud cover for clouds with CTP less than 440 hPa
cla_vis006 = Simulated cloud albedo at 0.6 micron
cot = grid average cloud optical thickness
cth = simulated cloud top height
ctp = simulated cloud top pressure. Derived from linear-averaging of the sub-grid CTP
ctp_log = simulated cloud top pressure. Derived from log-averaging of the sub-grid CTP
hist2d_cot_ctp = CTP--tau hits based on sub-grids in each grid box and only including clouds that have tau > 0.20
iwp = simulated grid average ice water path
lwp = grid average liquid water path
