  • Chemical Mechanism Tables: Tables of model species and chemical reactions in each chemical mechanism available in v5.3.

  • Developers' Guide: A guide to version control practices and expectations adopted by the CMAQ development team and enforced on itself and any other collaborators who wish to contribute code.
