I am using wrf-chem model for my research on air quality in India. After successfully getting the output file from wrf.exe, I want to convert it to .ctl and .dat for post-processing in grads. But ARWpost gives the following error:

ARWpost v3.1

FOUND the following input files:


WARNING --- I do not recognize this data.
Will make an attempt to read it.

Please help me in resolving the issue
Can you attach your namelist.arwp file, along with one of the wrfout* files that is not working? I'd like to try to repeat the problem. If the wrfout* file is too large to attach, please see the home page of this forum for instructions regarding uploading large files. Thanks!
