CTSM 5.3 Spinup and HIST on ne30 grid

[wwieder]

Description:
Identical to #65, but on the ne30 grid. This can be a full historical run so we also get a restart in 2000 for B or F2000 cases. Are there other years we should have here for CAM testing (e.g. 1979?).
09/11/24 - STOPPED because fire model was not actually on in the tag used here.

1. I pushed tag branch_tags/ctsm5.3.n02_ctsm5.2.027 to escomp, so you should be able to check it out now. This represents the most current version of the branch in PR CTSM5.3.0: New raw pft/lai/glc-behavior/soilcolor/fire datasets ESCOMP/CTSM#2500 (i.e. this commit).
2. I have already started make all. Depending on how soon you can start CTSM 5.3 Spinup and HIST on ne30 grid #66, you can pick which fsurdat file to use:

• already existing /glade/derecho/scratch/slevis/temp_work/new_rawdata/tools/mksurfdata_esmf/make_all_20240830/surfdata_ne30np4_hist_1850_78pfts_c240830.nc with the CAVEAT that you pointed out that you need a specific ne30 grid, and I do not remember if it's this one or pg2 or pg3. Same comment for the corresponding landuse.timeseries_ne30np4_SSP2-4.5_1850-2100_78pfts_c240830.nc.
• in the queue to be generated soon, likely in the next few hours /glade/derecho/scratch/slevis/temp_work/new_rawdata/tools/mksurfdata_esmf/surfdata_ne30np4_hist_1850_78pfts_c240905.nc and landuse.timeseries_ne30np4_SSP2-4.5_1850-2100_78pfts_c240905.nc with the same CAVEAT regarding pg2/pg3.

[olyson]

The last ne30 simulation I ran used this one:

/glade/campaign/cesm/cesmdata/inputdata/lnd/clm2/surfdata_esmf/ctsm5.2.0/surfdata_ne30np4.pg3_hist_1850_78pfts_c240216.nc

It had pg3 in the name.

[slevis-lmwg]

Ok, pg3 it is then.

[olyson]

The new one seems to be complete, so I'll use that:

/glade/derecho/scratch/slevis/temp_work/new_rawdata/tools/mksurfdata_esmf/surfdata_ne30np4.pg3_hist_1850_78pfts_c240905.nc

@olyson I don't know if you followed last week's events (after I took off for the weekend on Thurs). I am not 100% caught up, but I assume that this simulation needs to wait for the newest ne30 fsurdat file. For info, see ESCOMP/CTSM#2500 (comment)

[olyson]

Yes, thanks, I stopped it.

[slevis-lmwg]

I submitted a new make all a few minutes ago, so the new ne30 file should be ready by morning.

I'm generating the new datasets with the new escomp tag branch_tags/ctsm5.3.n03_ctsm5.2.028 in case this matters.

[wwieder]

Thanks for following up here @slevis-lmwg and @olyson I think we're all on the same page (waiting on ne30spinup until after new surface datasets are made), but we can touch base in regularly scheduled meetings this week.

[slevis-lmwg]

@olyson the new fsurdat/landuse files:

/glade/derecho/scratch/slevis/temp_work/new_rawdata/tools/mksurfdata_esmf/surfdata_ne30np4.pg3_hist_1850_78pfts_c240908.nc
/glade/derecho/scratch/slevis/temp_work/new_rawdata/tools/mksurfdata_esmf/landuse.timeseries_ne30np4.pg3_SSP2-4.5_1850-2100_78pfts_c240908.nc

[olyson]

I've restarted the spinup with the new fsurdat file. Although has anyone plotted up the soil texture to verify it is good?

[wwieder]

I'll do that now. Good idea

[wwieder]

Africa's back, here for %Sand, but also good for clay and organic

I realized the purpose of this run is to generate initial conditions for use in coupled model simulations. This is great, but it also presents challenges as the CRUJRA forcing data doesn't have data over Antarctica, which caused issues in SMILE extensions. I wanted to raise the issue here, but likely need to have a discussion with @dlawrenncar, Sam L and Keith about how to address this?
