Issue in running WRF-Chem

[Akhtar Memon]

I am running WRF-Chem with EDGAR, MEGAN, FINN and mozbc but an error occurs. Namelist and error files are attached. Your suggestion is required, please.

Hi Akhtar, 

can you try adding mozart_ph_diag = 1 to your namelist?

Issue could not be resolved by adding mozart_ph_diag = 1 in my namelist. Still the error is the same. Kindly suggest, please.

HI Akhtar

here are a few things to consider:
- Set debug_level=12, maybe this way you get more information on your error in your log file
- Have you looked through all log files whether any of them have more information on why the model failed?
- Do your wrfchemi and wrffirechemi inputs indeed only have 24-hour resolution?
- change the following namelist entries to:
   chem_adv_opt = 2

   moist_adv_opt=2

   scalar_adv_opt=2
   tke_adv_opt=2
   phot_op=4   (see https://www2.acom.ucar.edu/wrf-chem for more information)
   conv_tr_aqchem = 0
