Need land files for resolutions besides 120km

[gdicker1]

As reported by @dazlich, runs fail at resolutions higher than mpasa120 since updating EarthWorksOrg/CTSM (clm) to be based on ctsm5.2.X.

At least the fsurdat files need to be regenerated; the ctsm5.1 files are missing a pct_ocean variable.

From looking at the current namelist_defaults_ctsm.xml there are some files for 60, 15, and 3.75km MPAS resolutions. However, I don't know if it's important that these files only apply with `use_crop=".false."

<fsurdat hgrid="mpasa60"   sim_year="2000" use_crop=".false.">
lnd/clm2/surfdata_esmf/ctsm5.2.0/surfdata_mpasa60_hist_2000_16pfts_c240216.nc</fsurdat>
<fsurdat hgrid="mpasa15"   sim_year="2000" use_crop=".false.">
lnd/clm2/surfdata_esmf/ctsm5.2.0/surfdata_mpasa15_hist_2000_16pfts_c240216.nc</fsurdat>
<!--
<fsurdat hgrid="mpasa15-3" sim_year="2000" use_crop=".false.">
lnd/clm2/surfdata_esmf/ctsm5.2.0/surfdata_mpasa15-3_hist_2000_16pfts_c240216.nc</fsurdat>
-->
<fsurdat hgrid="mpasa3p75" sim_year="2000" use_crop=".false.">
lnd/clm2/surfdata_esmf/ctsm5.2.0/surfdata_mpasa3p75_hist_2000_16pfts_c240216.nc</fsurdat>

Later in the file we see the ctsm5.2 fsurdat files for mpasa480 and mpasa120

<fsurdat hgrid="mpasa480"  sim_year="2000">
lnd/clm2/surfdata_esmf/ctsm5.2.0/surfdata_mpasa480_hist_2000_78pfts_c240216.nc</fsurdat>
<fsurdat hgrid="mpasa120"  sim_year="2000">
lnd/clm2/surfdata_esmf/ctsm5.2.0/surfdata_mpasa120_hist_2000_78pfts_c240216.nc</fsurdat>

Searching this file for other mentions of 'hgrid="mpasa', we may have to also look at files for flanduse_timeseries. There is currently only files for mpasa120 resolution:

<flanduse_timeseries hgrid="mpasa120"      sim_year_range="1850-2000"
>lnd/clm2/surfdata_esmf/ctsm5.2.0/landuse.timeseries_mpasa120_SSP2-4.5_1850-2100_78pfts_c240216.nc</flanduse_timeseries>

AND

<flanduse_timeseries hgrid="mpasa120"      sim_year_range="1850-2100" ssp_rcp="SSP2-4.5"
>lnd/clm2/surfdata_esmf/ctsm5.2.0/landuse.timeseries_mpasa120_SSP2-4.5_1850-2100_78pfts_c240216.nc</flanduse_timeseries>

The PR to create CTSM files for EarthWorks may be paused for a bit. It looks like there's some issues with the mksurfdata_esmf tool not filling in the data for soil categories in some regions. This may be fixed soon when CTSM/5.3 comes out and is incorporated into CESM (may need to update the EarthWorks tags again to allow this fix).

See: ESCOMP/CTSM#2744

@dazlich @sherimickelson @areanddee, what are your thoughts? Would it be better to get things functional sooner (i.e. go ahead and create some CTSM files) or to wait for the CTSM tool update?

[gdicker1]

Given discussion in the regular EarthWorks SEs meeting today, I will move this forward. It will be better to be functional sooner.
