Running CTSM5.3 with CPLHIST

[bmraczka]

Good evening,

I am trying to run a basic hybrid simulation using old CPLHIST files (CAM6 reanalysis) with the newer cesm coupler setup (nuopc). I am following the instructions from a previous thread on this forum which described how to adapt the user_nl_datm stream file. I am using the ctsm5.3.021 tag with compset 2000_DATM%GSWP3v1_CLM60%BGC-CROP_SICE_SOCN_MOSART_SGLC_SWAV_SESP. When creating the case there is an error during the buildnml step as follows:

..
..
Create namelist for component datm
Calling /glade/derecho/scratch/bmraczka/CESM3_source/ctsm5.3.021/components/cdeps/datm/cime_config/buildnml
ERROR: Error in parsing namelist: 'CPLHISTForcing.Solar:datafiles' is not a valid variable name

My case folder is located here: /glade/work/bmraczka/cases/ctsm5.3.021/clm6_hybrid_e5, which contain the user_nl_datm files (e.g. user_nl_datm_0001).

Clearly there is some incompatibility with how I set up the namelist CPLHIST variables, but I am not sure what it is. Also attaching an example datm namelist file (user_nl_datm_0001) and output (CLM6_hybrid_freerun.out) from my scripting used to set up the case (/glade/work/bmraczka/DART/models/clm/shell_scripts/cesm3_0).

Looking in /glade/work/bmraczka/cases/ctsm5.3.021/clm6_hybrid_e5,
I have spotted the following incompatibility relative to one of my cases that used datm streams (/glade/u/home/slevis/cases_LMWG_dev/ctsm53026_BNF_hist):

Your user_nl_datm_streams are blank, while your user_nl_datm files contain what I would have expected in the user_nl_datm_streams.
