Field missing from restart file

[hsjung]

What version of the code are you using?
CESM v2.1.5


Have you made any changes to files in the source tree?
None

Describe your problem or question:
Hello,

I am trying to branch from a restart file on glade: /glade/campaign/cgd/ppc/cesm2_tuned_albedo/b.e21.BHISTsmbb.f09_g17.CMIP6-historical.118/rest/2010-01-01-00000.
I have successfully built the case using compset BHISTsmbb and resolution f09_g17 with no explicit changes made to the namelist of the land model.
I also staged the restart file into my run directory.

The run fails during land model initialization with error
: ERROR: Field missing from restart file: rc13_canair

So I'm guessing that the BHISTsmbb compset that I'm using is probably different from what was used to generate the restart file.
I'm wondering what namelist in the CLM model I should try to modify to not need to use the rc13_canair variable?

Thank you in advance!

I think you need
use_c13 = .false.
use_c14 = .false.
in user_nl_clm.

If you still have trouble starting, try "hybrid" instead of "branch" since hybrid runs are much more flexible than branch runs.
