CIN in CAM outputs

[AndrewY]

Hi,

I'm running CESM2 with the compset FHIST. I would like to include convective inhibition (CIN) in the model outputs. I managed to add that field to history tapes by modifying user_nl_cam but it turned out the CIN for every grid in the output was 0 J/kg. Does anyone know why this happened? Could this issue be related to the type of compset?

Thank you!

Looking at the code for cam6_3_072, I see an addfld call for 'CIN' in convect_shallow.F90, but I do not see a corresponding outfld call. I believe you have found a bug, and I opened an issue in CAM. You can see the bug report at: convect_shallow.F90 has CIN in an addfld call, but there is no corresponding outfld call · Issue #674 · ESCOMP/CAM

As I am a software engineer, I am not sure what value should be written out to this field. I would suggest that you figure out which variable should be output and add an outfld call to your version of the convect_shallow.F90 code.

Please do follow the discussion at: convect_shallow.F90 has CIN in an addfld call, but there is no corresponding outfld call · Issue #674 · ESCOMP/CAM

It sounds like it is not as easy a fix as I was hoping it would be.

FYI, the only CIN data around are from WACCM, not CAM.
