Specific notes

Contributors other than yourself, if any:

CTSM Issues Fixed (include github issue #):

Are answers expected to change (and if so in what way)? No

Any User Interface Changes (namelist or namelist defaults changes)? Yes

Does this create a need to change or add documentation? Did you do so? No No

Testing performed, if any: Will run aux_clm to move to b4b-dev

I did a quick skim over this and this looks good to me. I'll rebase this PR to go to b4b-dev, which should be fine without any trouble. Sometimes you have to rebase the branch when that's done, but I don't expect that now.

The one thing noticeably missing is an updated parameter file with the parameters moved to it.

Adding next to talk about who will shepherd this in.

parameter file location: /fs/cgd/csm/inputdata/lnd/clm2/paramdata/ctsm5.3.041.Nfix_params.v13.c250221_upplim250_add_nml.nc

[ekluzek]

We talked about this and will bring it in on b4b-dev.

Paused testing because need to bring the new params (see post above) to the latest paramfiles:

OK ./build-namelist_test.pl
./run_sys_tests -s aux_clm -c ctsm5.4.001 --skip-generate
./run_sys_tests -s aux_clm -c ctsm5.4.001 --skip-generate --skip-git-status

Before I add the new params to paramfiles:

• [x] list the latest paramfiles on master and b4b-dev master currently ctsm5.4.004 has the latest and Erik tells me that we do not expect other paramfile updates:

<paramfile phys="clm6_0" >lnd/clm2/paramdata/ctsm60_params.c251211.nc</paramfile>
<paramfile phys="clm5_0" >lnd/clm2/paramdata/clm50_params.c250311.nc</paramfile>
<paramfile phys="clm4_5" >lnd/clm2/paramdata/clm45_params.c250311.nc</paramfile>

ctsm60 and clm50 are the paramfiles to update, not clm45.

Consider the new tool in #3622 if needed.
