New Mesh: ECwISC30to60E3r2

[xylar]

Long name: ECwISC30to60L64E3SMv3r2

As with previous versions of the mesh, this Eddy Closure (EC) mesh has:

• 30 km resolution at the equator
• 60 km resolution at mid latitudes
• 35 km resolution near the poles

Mesh, initial condition, dynamic adjustment and files for E3SM are on Chrysalis at:

/lcrc/group/e3sm/ac.xylar/compass_1.2/chrysalis/e3smv3-meshes/ecwisc30to60e3r2

Checklist

• Document (in a comment titled Testing in this PR) any testing that was used to verify the changes

I am concerned about this seemingly unrealistic feature in Alaska. I'd be curious to hear if this was intentionally included for some project need

I am concerned about this seemingly unrealistic feature in Alaska.

@alicebarthel: those two islands were added as land blockage features during the last iteration of the ARRM mesh (#414). Here is the geometric_features PR with details about that: MPAS-Dev/geometric_features#184

An E3SM JRA1.5 simulation with this mesh has been reviewed here:
https://acme-climate.atlassian.net/wiki/spaces/OO/pages/3904307201/Review+ECwISC30to60E3r2
and the results have been approved. This is considered to be sufficient testing for this PR to be merged. The next steps will be to open an E3SM PR to integrate the mesh, and run 1 or more B-cases to evaluate the mesh in the coupled climate.
