Non-0-diff Updates 2021-04-15

Zero-diff to previous release: NO

Restart Changes: YES

History Changes: YES

Major Non-0-diff changes include:

1. Modified PCHEM interpolation that fixes the problem of negative PCHEM tracers.
2. A bug fix to atmOcnIntlayer consistent with what was applied to GEOS-FP GEOS-5.27.1 (02/2021) which mitigates anomalous spikes in TSKINWTR and related fields when the sea ice fraction departs 100%.
3. Changed scaling and cleaned up Henry's law code in ConvPar_GF_GEOS5 (bug fix, non-zero diff for GOCART).
4. Update to use the 2020 NRL Solar file.

Major 0-diff changes include:

1. Fix DUAL_OCEAN options in coupled model to only work with MOM5 (It does not and can not work with MOM6).
2. Added diagnostic output for NH3, NH4A convective scavenging to GEOS_MoistGridComp used for GOCART evaluation.
3. Revive OceanBioGeoChem.
4. Fixed CMake bugs for DAS build only libraries.
5. Upticks of FVdycoreCubed_GridComp, fvdycore, and cmake repos.

Upgrade to ESMF 8.1.0

Zero-diff to previous release: YES

Zero-diff to regridding: YES

Restart Changes: NO

History Changes: NO

Major changes include:

1. Upgrade to ESMA_env v3.2.0 whose main change is updating to ESMF 8.1.0, which is needed for MAPL development. All testing has shown it zero-diff to GEOSgcm with ESMF 8.0.1. Tests were run from C12 to C720 as well as Replay and MOM6. However, ESMF notes that there are changes in some regridding situations which could produce non-zero-diff results.

Updates 2021-04-06

Zero-diff to previous release: YES for hydrostatic, NO for nonhydrostatic

Zero-diff to regridding: YES

Restart Changes: NO

History Changes: NO

Major changes include:

1. parallel_build.csh now accepts a -hydrostatic or -nonhydrostatic argument during building. If no argument is provided the model will build hydrostatically as before. Therefore, setup scripts were modified depending on what -DHYDROSTATIC option was supplied to CMake. If -DHYDROSTATIC=ON then it will assume the user wants to use hydrostatic dynamics options and vice versa.
2. Fixed decomposition regression for nonhydrostatic model.
3. Updates from ADAS 5.27 folded into git GMAO_Shared v1.3.9. This brings the GEOSadas code closer to the current GEOSgcm.
4. Upticks in MOM6, MAPL, env and other repositories.

Zero-diff to previous release: YES

Zero-diff to regridding: NO for agcm_import_rst

Restart Changes: NO

History Changes: NO

Major changes include:

1. Moved GOCART legacy to be sourced from separate GOCART repository.
2. Update to MOM6 geos/v2.0.0 and update to FMS geos/2019.01.02+noaff.6
3. Bug fix for regrid.pl which can cause non-0-diff regridding for agcm_import_rst.
4. Fixed MOM6 diagnostics to use correct netcdf reference year.
5. Fix bug in gustiness calculations.
6. Fixed a bug in rotation angle for surface ocean stress.
7. DSO's for mom5 and mom6.
8. GAAS Replay fix.
9. Add MOM.res.nc to the list of restarts that are checked in regression testing.
10. Remove OCEAN_PRELOAD since it is not needed with the DSO.

12. Remove CMIP_1977_1982 directory in GEOS_Util/pre/NSIDC-OSTIA_SST-ICE_blend.
13. Update binarytile.x for river routing.
14. Bug fix for edge level arrays out-of-bounds in Lighting_mod.
15. Plot updates for stats.

Restart Changes: NO

History Changes: YES - Roundoff differences in TSOIL1 and TSOIL2

Major changes include:

1. Soil temperatures export variables (TP's) are now in units of Kelvin throughout the Catch and CatchCN. Note: this has introduced roundoff differences in TSOIL1 and TSOIL2 output.
2. New MOM6 configuration (OM4), and a bug fix in MOM6_Plug.
3. Update default coupled model surf collection with a few addition fields.
4. Fix saltwater_internal splitting to work with in AMIP and EMIP mode.
5. Add ASSERTs to RRTMG to test input sanity.
6. Adds a -partition option to mk_restarts so that there can be a -partition option in regrid.pl.
