Land ice variables appear missing in WACCM simulations

Hello,
I'm interested in output from these WACCM runs that were performed at NCAR:

SSP585
/glade/collections/cdg/data/CMIP6/ScenarioMIP/NCAR/CESM2-WACCM/ssp585/r1i1p1f1/
case root: /glade/work/cmip6/cases/ScenarioMIP_WACCM/b.e21.BWSSP585cmip6.f09_g17.CMIP6-SSP5-8.5-WACCM.001

SSP126
/glade/collections/cdg/data/CMIP6/ScenarioMIP/NCAR/CESM2-WACCM/ssp126/r1i1p1f1/
case root: /glade/work/cmip6/cases/ScenarioMIP_WACCM/b.e21.BWSSP126cmip6.f09_g17.CMIP6-SSP1-2.6-WACCM.001

Unfortunately, I found that the SSP126 simulations are missing land ice variables (realm LImon) that the SSP585 does have. In fact it has only 7 variables whereas SSP585 has 29. Same story for other scenarios.

Would anyone know to why that is? I glanced the namelists of the original cases (paths above) but there don’t seem to be obvious differences in the FINCLS, so I am guessing this should be the result of a different treatment in post-processing.

I'll take a look.

Thanks for finding this out Gary, although it's a pity. Do you think the raw variables are still stored somewhere? Or have they been erased after the CMIP6 post-processing has been done.

The raw data aren't useful in their current form and since CMIP6 didn't require those fields for those experiments, the data aren't available.
