Land ice variables appear missing in WACCM simulations

[l_vankampenhout@uu_nl]

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 Gary! Did you find out anything yet?

Thanks Gary! Did you find out anything yet?

Going by the CMIP6 requirements for LImon variables from SSP experiments, only SSP5.85 runs are asked to have the "missing" fields (which are all defined as part of ISMIP6).

See

Data Request Record: [requestLink]ISMIP6-LImon-01

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.
