error while running wrf-chem

[Vaishnavi_198]

Hey everyone,

I tried to run a wrf-chem simulation after preparing all the emission input files, like fire emission, biogenic emission and anthropogenic emissions but I ran into the error. I do not know what is wrong. I am using WRF version 4.3.3. Please find attached the rsl file and namelist.input file

Hi @Vaishnavi_198,

I don't know if you managed to fixed the error in the end. However the solution is to include the string "V4" (referring to the WRF version being >= 4.0) in the TITLE attribute of your emission files. Hopefully it will help other people facing the same problem.
