Add generation of 1/12deg grid files for ocean and ice

[DeniseWorthen]

DESCRIPTION OF CHANGES:

Adds 1/12 deg ocean and ice grid file generation.

TESTS CONDUCTED:

If there are changes to the build or source code, the tests below must be conducted. Contact a repository manager if you need assistance.

• Compile branch on all Tier 1 machines using Intel (Orion, Jet, Ursa, Hercules and WCOSS2).
• Compile branch on Ursa using GNU. ee4a46a
• Compile branch in 'Debug' mode on WCOSS2. 49b3d98
• Compile with Doxygen on any machine with no errors. ee4a46a
• Run unit tests locally on any Tier 1 machine. ee4a46a
• Run relevant consistency tests locally on all Tier 1 machines.

Optional test.

• Run full set of chgres_cube consistency tests on Ursa.

Describe any additional tests performed.

DEPENDENCIES:

The MOM6 supergrid, bathymetry and mask files need to be added to the glopara fix directories. Currently the rt.sh for the utility is pointing to a staged set of 1/12deg input data.

• Add 1/12deg MOM6 ocean grid files NOAA-EMC/global-workflow#4268

ISSUE:

• fixes Add 1/12deg OCN/ICE configuration to cpld_gridgen #1046

@BrianCurtis-NOAA Please assign me. Thanks.

@BrianCurtis-NOAA I don't intend on retaining baselines for the 1/12 deg at this time, since it is unclear whether RTOFS will use any of the additional files generated (and they're big files, ~4GB).

The setting in rt.conf which will generate the needed grid files for the mx008 case is

diff --git a/reg_tests/cpld_gridgen/rt.conf b/reg_tests/cpld_gridgen/rt.conf
index c908c5f6..9618010d 100644

In this case, since we're only using a DATM, there is no need to generate any mapped ocean masks on the ATM tiles, so the ATM resolutions are set to a null value.

I can run the cpld_gridgen baselines and verify that they don't change. What other testing should I do?

[BrianCurtis-NOAA]

run the reg_tests for the component your modifying, verify it compiles, and the unit testing doesn't fail. If there's any documentation changes needed, please make them.

@BrianCurtis-NOAA I remember asking George this also....the PR template asks to confirm compilation w/ Intel, but AFAIK intelllvm is the compiler used by UFS_UTILS. Does the PR template need to be updated, or is the request to actually compile w/ Intel?

template update is on my todo

[DeniseWorthen]

OK, thanks. I think I've completed all the checkmarks then. All current baselines pass, as expected.
