Double counting NH3 emissions when using NH3 Bidi flux in CMAQ

CMAQ CMAQ-PREP
5

Thanks a lot for the information.

I searched for the terms DepMod, stage and m3dry in my CMAQv5.3.2 (cb6r3_ae7) runscript, and did not find any of them. Then I check my CMAQ BLD* directory when I saw m3dry.F and m3dry.o files, which confirm that I am indeed running the m3dry module.

Actually, my CMAQ run has not aborted at these NaN values of NH3 and NH3_Emis in the CCTM_DEPV_* CMAQ output files, or the Infinity values of standard deviation (screenshot shown in the post NaN values of NH3_Emis variable in CCTM_DRYDEP_* file) of all FEST model output files (input to CMAQ bidi).

My questions here:

  1. Is it a possibly a problem starting with the FEST input files that I downloaded from the repository?
  2. Is there any preference between the two modules m3dry and stage for NH3-bidi process? Would using stage have avoided getting NaN values for NH3 and NH3_Emis variable in CCTM_DEPV_* files?
