Hi, everyone.
I am new to WRF-Chem. I am following a tutorial video from youtube and try to run wrfchem with emission data. But I cannot get the result when I am running wrf.exe

The attachments are my namelist.input and namelist.wps.

I am using ubuntu22.02 in WSL.

I have tried to use other chem_opt, 300 and 303 both work for me but 301 doesn't work.

Have you tried running with a photolysis option? I just ran into the same error when I set phot_opt=0. It disappeared when I set phot_opt=1. What the exact cause might be, I am not sure though.

Thank you for your comment. I ran into the same error and when I set phot_opt = 1, it disappeared.
