I am now running WRF-Chem3.9.1 in air pollution forecasting. But I find that the model ran more slower than other typical air quality models (like WRF-CMAQ and WRF-CAMx). I believe that WRF-Chem treat the atmospheric processes more realistically than others, so I wish to apply WRF-Chem if its computation budget can be significantly reduced.

I apprecaite you very much if you could give me any suggestions.

Best regards
