For milestone Prototype 5 (which needs to be created)

We want/need the ability to couple with CICE6. Bob Grumbine currently working on it.

Please discuss in comments here what, beyond passing the regular NEMSCompsetRun, is needed or desired.

Also in comments, how we want to do this. e.g. it would be desirable to get rid of the links CICE_CAP and CICE in the main ufs-s2s directory.

@rgrumbine and @AvichalMehra-NOAA since our goal is to use CMEPS and that is currently working in a fork that @DeniseWorthen has created, can the CICE6 model be coupled to UFS-S2S by forking from Denise's fork to see what issues may occur.

We may need Tony's help (what is his github handle btw) to see how to build this though.

We discussed a plan of getting everything stable, off of Denise's fork, and into ufs-s2s within a couple of weeks. Can we complete all of that before trying to bring in CICE6? Too much in flux right now.

Tony is @apcraig

The major issue is not the Cap (CMEPS vs. NEMS), but CICE5 (which Denise et al. have been working with) versus CICE6 (which includes extracting Icepack and some new module naming + structure) and getting the FV3-MOM6-CICE6 app to compile and link in ways which are not excessively discrepant from either the CICE6 standalone or the FV3-MOM6-CICE5 methods already in place.

No worries on that. Thx I forgot about that? Yes let us wait till the merge to develop happens. And get that happening soon

 FV3 is updated to include the following:
* fv3atm issue ufs-community#37: fix the real(8) lat/lon in netcdf file
* fv3atm ufs-community#35: Reducing background vertical diffusivities in the inversion layers
* fv3atm ufs-community#24: bug in gfsphysics/physics/moninedmf_hafs.f
* fv3atm ufs-community#18: Optimize netcdf write component and bugfix for post and samfdeepcnv.f
* set (0-1) bounds for ficein_cpl
* remove cache_size due to lower netcdf verion 4.5.1 on mars
* Change ice falling to 0.9 in gfsphysics/physics/gfdl_cloud_microphys.F90

NEMS is updated to remove ice-ocean merge in prep_atm:
* The following fields are now exported to FV3 as ice-only fields:
 mean_sensi_heat_flx
 mean_laten_heat_flx
 mean_up_lw_flx
 mean_evap_rate
 mean_zonal_moment_flx
 mean_merid_moment_flx

MOM6 is updated to GFDL's 20200108 dev/master:
* MOM6 adds field in MOM.res_1.nc (kg_m3_to_R). All other files are reproducible with previous baseline
