Rollback nint()

Zero-diff to previous release: NO

Restart Changes: NO

The only change in this release is moving back to using int() not nint() in GEOS_Shared/GEOS_Utilities.F90 which may cause crashes if the Debugging flags are on. Nevertheless, this is a non zero-diff change to the gcm.

EMIP and Other Updates

Zero-diff to previous release: YES

Restart Changes: NO

3. Removed S2S history template with confusing name.
4. Adds an fv3_setup and fv3.j script for the FV3 Standalone.
5. Allows the JCAP functionality to work again in mkiau gridcomp as that needs the r4 version of ncesp_sp in gmao_transf.
6. Modify mpirun flags for Open MPI 4.0.4.
7. Updates to plots.

New MOM6, NCAR GWD, and Other Updates

Zero-diff to previous release: YES - for default 72L-1MOM configuration

4. Updated MOM5 version (CMake changes)
5. Run time switch between MOM5 or MOM6
6. Updates for JEDI Integration
7. Updated FMS
8. Sparsed out FVdycore_GridComp and ARIESg3_GridComp dynamical cores. Sparsed out GMAO_pilgrim from GEOSgcm_GridComp.
9. Update Aerosol Chemistry BCs to match new vertical levels.
10. Additional question in setup scripts for:
    1. Chosing microphysics option
    2. Chosing hydrostatic/non-hydrostatic mode

Updated Vertical Levels

Zero-diff to previous release: ONLY 72L 1-MOMENT DEFAULT CONFIG

Restart Changes: NO

Only 0-diff for 72-level 1-MOMENT default configuration. Non-0-diff for ALL others. Major changes include:

1. Support for increased vertical resolution and updates in FV3 and GFDL. New 71, 91, and 181-level options which have eta distributions similar to the ECMWF 137-level option. New 127-level option is similar to NCEP. Retuned surface mixing results in non-0-diff changes to the 132-level option.
2. Updated MPI Settings for running at NCCS.
3. New updates from S2S3 tag in CVS.
4. Updates to coupled plotting package (coupled_diagnostics)
5. Fixed MOM_GEOS5Plug MAPL Timers for RUN2.
6. River routing updates.

5. Compute the lightning flash rate (LFR) online following the approach used by GEOSCHEMchem_GridComp. The LFR is calculated in MOIST and then made available to other components as a new export field (LFR_GCC).
6. Modified the mk_Restarts script to run on SLES-12.
7. Update RRTMGP to Pincus 2020-Feb-12.
8. New Surface parameter resource file (GEOSsurface_GridComp/Shared/GEOS_SurfaceGridComp.rc) to avoid having to add new parameters into AGCM.rc.tmpl and prepare for further science development.
