I run WRF-Chem to simulate PM emission over India and Russia using GOCART aerosol scheme (chem_opt=300). I originally only wanted to simulate dust without chemistry, thus I did not provide emission data using prep_chem_src utility (Freitas et al., 2010). Anyway, the results show not only dust, but also PM2.5, PM10 BC, OC, DMS, etc.
Sorry for the stupid question, but how did WRF-Chem simulate these particulates without emission data (anthropogenic, biogenic, gocart bg etc.) from prep_chem_src? Were they just generated from WPS_GEOG data? Are emission data not needed if we want to simulate aerosols only?
Thank you.
