Failing attempt to write out variable TKE&IC

[camillaws]

Hi,
I am new to CAM6, but I would like to study turbulence in CAM6 simulations, and I have found a field named 'TKE&IC' in the history field list CAM History Fields
I have been unsuccessful in trying to figure out what the '&IC' in the field name refers to - my guess is that it's something to do with initial conditions, but that's just a guess. I try adding this variable to my namelist, as
fincl4 = 'TKE&IC:I', with corresponding mfilt=24 and nhtfrq=-1,
to get it written out instantaneously each hour, in files with one value for the 24 hours of a day.
However, my output files do not end up containing this TKE variable at all. I wonder if anyone have any experience with this or any of the other '&IC' variables, and know how to get a hold of them, if at all possible?

Cheers,
Camilla

You are correct that the '&IC' suffix is related to fields output to the initial file. The fact that TKE&IC appears in the master list of history fields that you linked to is a bug. The cam6 physics package uses the CLUBB package for vertical diffusion and PBL calculations. The TKE diagnostic is not available from CLUBB. I would suggest looking in the file src/physics/cam/clubb_intr.F90 and searching for 'addfld'. That will show the diagnostics available from the CLUBB package.
