I am using simulating PM2.5 concentration across the U.S. with CMAQV5.3.2. Although I managed to run CMAQ and got the simulated results, the model performance was not as good as I expected when comparing it with the observed PM concentration from the AQS network. I downloaded the met data from the CMAS data warehouse directly and used SMOKE to get the emission input from NEI2015. I did the simulation for the year 2015 and the scripts containing all my settings for CMAQ are attached (run_cctm_201507_12US1.csh (36.1 KB)
). Any suggestions on how to improve the model performance will be so appreciated.
