CLM not outputting NPP in BGC_CROP mode

[James King]

Hi all,

I'm running CESM2 with CLM5 in BGC_CROP mode. The model fails very quickly and the error is in the lnd log file

htapes_fieldlist ERROR: NPP in fincl( 29 ) for history tape
2 not found
ENDRUN:
ERROR: ERROR in histFileMod.F90 at line 699

I have asked the model to output NPP in user_nl_clm. The model is definitely not set up to use SP mode, so I'm not sure what the problem is. Logs are attached along with my user_nl_clm and lnd_in.

Thanks,

James

It doesn't look like you are running with BGC-CROP. The lnd_in namelist settings indicate that BGC-CROP is not active (e.g., use_cn = .false., use_crop = .false., etc.)

Hi Keith,

I specified it in the compset longname, which is
HIST_CAM60%CCTS2_CLM50%BGC-CROP_CICE%PRES_DOCN%DOM_MOSART_CISM2%NOEVOLVE_SWAV

and it's in README.case

2021-11-01 08:30:08: Component LND is clm5.0:BGC (vert. resol. CN and methane) with prognostic crop:

Any idea what might have switched it off?

Cheers,

James

I tried that compset with release-cesm2.2.0 and it seemed to work fine.
What do you have for "CLM_BLDNML_OPTS" in your env_run.xml?
I have:
value="-bgc bgc -crop"

Hi Keith,

./xmlquery CML_BLDNML_OPTS

returns

CLM_BLDNML_OPTS:

This may be a result of me fiddling with the caseroot while trying to set CLM to cycle over a single year of transient landuse timeseries data. If I set

CLM_BLDNML_OPTS="-bgc bgc -crop"

do you reckon that would work? Or should I just rebuild the case from scratch?

Cheers,

James

I would think changing CLM_BLDNML_OPTS should work.

I would think changing CLM_BLDNML_OPTS should work.

Thanks, I'll give it a go
