CMOR-ization?

[aswann2]

Are there any currently working scripts for derecho or casper to CMOR-ize CESM output? (I'm assuming no but would love to learn that I am wrong!)

If not working, are there still scripts we could read that would contain the info needed to do this by ~hand? - i.e. the variable name and unit conversion mapping? We need to convert a handful of variables across atm, land, and ocean to contribute to a MIP.

Thanks for any ideas you have!

This functionality is under current porting and development but isn't currently available.

Ok thanks! Can you point me to anything I can look at right now as a guide for the variable name and unit conversion mapping?

Thanks so much! That's a big help for mapping the variable names. Are the unit conversions be included there? It looks like there are a few variables that have multipliers on them, but one of the variables I'm looking at does not and I think that it should. Is there a separate file for the unit conversions?

Unit conversions are denoted in the file. What variable are you examining?

I was mistaken about one of my variables which turns out to be in the correct unit. But I'm having issues with precipitation.

"pr" is I think supposed to be in kg/m2/s
The table lists:
pr=PREC_F
I do not have this variable in my standard CAM output. One place in the table where pr is listed has a comment

pr=PREC_F  #Isn't this PRECT from CAM?

I do have PRECT as an output variable, but the units listed are m/s, which requires a factor of 10^3 (kg/m2/s of water = mm/s)

"PREC_F" is precipitation but from the ocean model. You are correct that "pr" for atmosphere is PRECT*1000, to convert m s-1 to kg m-2 s-1.

 

[aswann2]

Ah, ok. pr is listed as PREC_F even in the Amon table.

 

[strandwg]

Ah, ok. pr is listed as PREC_F even in the Amon table.

I've replaced that CESM_MastList.def file with a version that's better annotated.

Great, thanks! That updates one of the other variables that appeared to be missing a unit conversion as well (co2) - now looks correct.
