As the title says. ## Dependencies - NOAA-EMC/jcb-gdas#66 - NOAA-EMC/global-workflow#3238 - Update of the static files in glopara: NOAA-EMC/global-workflow#3239 ## Work done in this PR Interp to low-resolution: - [ ] variance partitioning - [ ] preparation of the perturbations for the envar - [ ] hybrid weights - [ ] ... ## Testing Visual check showing the variance explained by the steric height (30 members)  left is native resolution, right is on the 1/2 deg grid. **"Science" note:** The explained variance above is almost the opposite to what I would have expected, and what we saw in the previous offline ensemble, or even what we see in tendencies. Check if there's a bug in the explained variance calculation. # Automated CI tests to run in Global Workflow <!-- Which Global Workflow CI tests are required to adequately test this PR? --> - [ ] atm_jjob <!-- JEDI atm single cycle DA !--> - [ ] C96C48_ufs_hybatmDA <!-- JEDI atm cycled DA !--> - [ ] C96C48_hybatmaerosnowDA <!-- JEDI aero/snow cycled DA !--> - [x] C48mx500_3DVarAOWCDA <!-- JEDI low-res marine 3DVar cycled DA !--> - [x] C48mx500_hybAOWCDA <!-- JEDI marine hybrid envar cycled DA !--> - [ ] C96C48_hybatmDA <!-- GSI atm cycled DA !-->
