Hello,
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:

FOUND the following input files:
/home/ksaurb/WRFV3/test/em_real/wrfout_d01_2018-01-25_00:00:00

Hi,
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!
