Postprocessing in cracmm

I ran the benchmark run for CMAQ_Cracmm Mechanism and now I am trying to use combine for post-processing.
I keep receiving this error :

ERROR Invalid syntax for field: PNA[2]!Peroxy

ERROR Cannot read PNA from INFILE2

should I change the combined script for Cracmm?


Hi Farzan,

One option is to skip the combine process and use the ELMO module within CMAQ to output the variables needed for AMET to the ELMO or AELMO output file.

There are also two namelist files for the cracmm mechanism that need to be used. I’ve updated the CRACMM run scripts to use these namelist files available here:
