@ekluzek - I plan to bring this to master combined with the NWP configuration (i.e., combining them into a single branch and making a tag from that). And before I bring this to master, I'll make tags of cime and mosart. So this isn't quite in its final form. But I think all of the necessary CTSM changes for the NLDAS grid are now in place, so I wanted to give you a chance to give this a quick look, if you want.

cime changes are documented in ESMCI/cime#3063 (Note that that uses a rebased version of the cime branch, but the changes are the same as the ones included here.)

@ekluzek per your request, I have run mkmapdata.sh with a global and regional grid:

For global:

cmdargs="-r 10x15 -f /glade/p/cesmdata/cseg/inputdata/lnd/clm2/mappingdata/grids/SCRIPgrid_10x15_nomask_c110308.nc -t global"
regrid_num_proc=8
echo "args: $cmdargs"
echo "time env REGRID_PROC=$regrid_num_proc ./mkmapdata.sh $cmdargs\n"
time env REGRID_PROC=$regrid_num_proc ./mkmapdata_test.sh $cmdargs

For single point:

cmdargs="-r 1x1_brazil -f /glade/p/cesmdata/cseg/inputdata/lnd/clm2/mappingdata/grids/SCRIPgrid_1x1pt_brazil_nomask_c110308.nc -t regional"
regrid_num_proc=1
echo "args: $cmdargs"
echo "time env REGRID_PROC=$regrid_num_proc ./mkmapdata.sh $cmdargs\n"
time env REGRID_PROC=$regrid_num_proc ./mkmapdata_test.sh $cmdargs

In both cases, I changed mkmapdata's grid list to just contain one grid:

    grids=(                    \
           "0.5x0.5_AVHRR"     \
          )

Both completed successfully.

I think this all looks good. Before coming to master, I'd like to see the external hashes changed to tags, and the input files all checked into inputdata (I checked the SCRIPgrid file and it wasn't, but didn't check others).

Yup, working on both of those things now. (I wanted to wait for review approval before adding the files to the inputdata repo.)
