hcru_hcru not recognized

[samrabin]

The following:
./create_newcase --case /glade/u/home/samrabin/cases_ctsm/halfdeg_test --res hcru_hcru --compset IHistClm50BgcCrop --run-unsupported
fails with ERROR: no alias hcru_hcru defined. The same respectively happens for --res 360x720cru. Am I doing something wrong? Is there some other way to set up a half-degree run?

This is with cime6.0.15, and my CTSM branch is up-to-date with ctsm5.1.dev088.

You could try hcru_hcru_mt13.

Yes exactly grid aliases are now required to include the ocean mask in it.

To see a list of valid grids you can use query_config --grids under cime/scripts.

Hmm, that works to make the case, but then I get the following error on trying to build:

Create namelist for component clm
   Calling /glade/u/home/samrabin/ctsm/cime_config/buildnml
ERROR: Command /glade/u/home/samrabin/ctsm/bld/build-namelist failed rc=255
out=
err=ERROR : CLM build-namelist::CLMBuildNamelist::add_default() : No default value found for flanduse_timeseries.
            Are defaults provided for this resolution and land mask?

It looks like there are a few different options for 360x720cru versions of those files in lnd/clm2/surfdata_map. Is there a way I can query what I used in a different case?

Yes, we don't currently have any 360x720cru grids in the default namelist_defaults_ctsm.xml file. There's an issue to add some. If you have a different case you would've had to explicitly add a setting for at least fsurdat in the user_nl_clm file for that case. Here it's asking for flanduse_timeseries, which must for a historical case. There are some of those available that you could use as well, so you'd add that to the user_nl_clm as well.

We did create some 360x720cru datasets for the latest TRENDY simulations, and I think those would the ones I'd most recommend.
