Description

Updates CICE6 to include option to run dynamics on the C-grid. Additional variables are added to default_vars and ice_in_template to specify the grid staggering used. The following will specify the current configuration by default:

export GRIDATM=A
export GRIDOCN=A
export GRIDICE=B

To specify C-grid dynamics for CICE6, export GRIDICE=C should be used. A new test cpld_control_ciceC_p8 is added.

Issue(s) addressed

• fixes Alllow CICE6 dynamics on the C-grid #1271

Testing

All baselines using CICE will change. This change is due solely to a change to how the 4 state variables (surface ocean u,v and surface tilts) are averaged. They will now be averaged as state variables instead of fluxes. See PR NOAA-EMC/CICE#50 description for more details.

@DeniseWorthen sounds like people running jobs on jet. I will run manually on jet now.

@DeniseWorthen sounds like people running jobs on jet. I will run manually on jet now.

@DeniseWorthen network on jet is not going thru. sounds only existing jobs are running.

[DeniseWorthen]

@jkbk2004 Do you want to wait until Jet is available? I think it is OK to skip a platform for a known reason like this. The next PR is MOM6 and it will also change baselines; only if someone tried to run this specific commit on jet would they have an issue.

[jkbk2004]

@DeniseWorthen @BrianCurtis-NOAA I agree to skip jet. I like to move on to merge in the pr.

[jkbk2004]

I am in the workshop at college park. Going out to have lunch. I will be back in an hour.

[jkbk2004]

can we start merging?

[DeniseWorthen]

CICE has been updated and the gitmodule reverted. This is ready for commit.
