Given the importance of representing biomass burning emissions, aerosol formation and feedback effects simultaneously in WRF-Chem, the file WRF-Chem_v.3.7.1_model_code_modification.tar.gz contains the modifications needed to couple the chemistry-aerosol mechanism CB05-MADE/VBS (chem_opt=132, with aqueous-phase chemistry) with the plume rise model (biomass_burn_opt=3, adapted from the default setting with MOZART). In addition, the AAS4WRF (Vara-Vela et al., 2016), a ncl based mass-conserving emissions preprocessor designed to create WRF-Chem ready emissions files from local inventories on a lat/lon projection, emerges as an alternative way to scale and convert the local emissions to those required for WRF-Chem.
