Long name: ECwISC30to60L64E3SMv3r4

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

This mesh differs from ECwISC30to60E3r2 (#689) only in having a smaller maximum Haney Number (rx1) of 5 instead of 10.

The mesh test case is a symlink to that of the ECwISC30to60E3r2 to guarantee that they are identical.

Initial condition, dynamic adjustment and files for E3SM will be on Chrysalis at:

/lcrc/group/e3sm/ac.xylar/compass_1.2/chrysalis/e3smv3-meshes/ecwisc30to60e3r4

This mesh name is being used for this instead of for topography smoothing (in #715) because we decided not to pursue any simulations with that version of the mesh.

Checklist

  • User's Guide has been updated
  • Developer's Guide has been updated
  • API documentation in the Developer's Guide (api.rst) has any new or modified class, method and/or functions listed
  • Documentation has been built locally and changes look as expected
  • The E3SM-Project submodule has been updated with relevant E3SM changes
  • The MALI-Dev submodule has been updated with relevant MALI changes
  • Document (in a comment titled Testing in this PR) any testing that was used to verify the changes
  • New tests have been added to a test suite

Up to now, topography smoothing has been disabled in MPAS-Ocean
init mode.  This merge adds config options to control it
(the number of iterations and the weight of a cell vs. its
neighbors in each iteration).  By default, topography smoothing
is still off.

We do not seem to need to decrease the Haney Number from 10 to 5 after all.
