CMAQv5.0 PM emitted species list

Jump to: navigation, search

Emitted Anthropogenic PM species in CMAQ (All species must be included in emissions input files, even if values are set to 0). Fine mode species will be split into I and J size bins within the CMAQ model. This table does not list PM emissions from sea salt or windblown dust which are calculated within the CMAQ model and are not included in the input files.
