The 2-D CMAQ wet deposition file (WETDEP) includes cumulative hourly wet deposition fluxes (kg/hectare) for selected model species. CMAQ calculates wet deposition for all of the species listed in the wet deposition include files within the mechanism include directories. Wet deposition include files exist for gas-phase species (GC_WDEP.EXT), aerosol species (AE_WDEP.EXT), and inert model species (NR_WDEP.EXT). You can remove species from these WDEP.EXT files to adjust the number of species that undergo the wet deposition process and are written to the WETDEP output file.
