CRU-JRA w/ Sturm_vegMods + new SNICAR (ctsm51_ctsm51d150_ne30pg3ne30pg3mg17_CRUJRA_ABCDE_1850AD, 1850pAD, 1850)

[wwieder]

Description: As with #33, this would use Sturm + ABCD veg mods + SNICAR updates, but with CRU-JRA (not GSWP3 forcing) in a BGC run.

This may be worth doing, as we see colder soil temperatures from #20, which may help our permafrost extent issues with Sturm snow thermal conductivity?

We also decided to turn on Meier roughness in the control (see Issue #35 ), so we do that here as well.

I will turn on Meier roughness since we decided to do that for the control. I just need to put in a SourceMod for the forcing height issue we found. And create a new parameter file with the ABCDE mods that is built off of the Meier parameter file.

[olyson]

@slevis-lmwg , the Meier parameter file doesn't seem to show up in the lnd_in when I turn Meier roughness on. I assume I have to put it in my user_nl_clm. Is this the most recent file that should be used with ctsm5.1.dev150? /glade/p/cesm/cseg/inputdata/lnd/clm2/paramdata/ctsm51_params.RMz0.c231011.nc

[slevis-lmwg]

Keith, that looks right to me.

[olyson]

Just to note that because of the recent problems on cheyenne this has been stalled in the queue since 11/25/23.

[wwieder]

Can we run on Derecho yet, or is this still not straightforward?
