I am running WRF-Chem V3.9.1 on a Cray machine for a Middle East domain and my chem_opt = 300. The model runs but I have noticed that the optical depth variables, TAUAER1, TAUAER2, TAUAER3, TAUAER4 in the hourly wrfout files do not change after the second hour (i.e., they are always the second-hour value) even though the dust fields (DUST_1-5, PM10, PM2_5_DRY) all change with the simulation time. My namelist.input file is attached here. I am wondering if anyone has any suggestions of how to solve this problem.
Thanks,
