The Community Multiscale Air Quality (CMAQ) model is an active open-source development project of the U.S. EPA that consists of a suite of programs for conducting air quality model simulations. CMAQ combines current knowledge in atmospheric science and air quality modeling, multi-processor computing techniques, and an open-source framework to deliver fast, technically sound estimates of ozone, particulates, toxics and acid deposition. For further information please visit the EPA website for the CMAQ system: www.epa.gov/cmaq CMAQv4.7.1 includes minor system updates to CMAQv4.7 which was released September 2008. CMAQv4.7.1 System Updates Improved time-step calculation schemes internal to the advection and aqueous chemistry modules New Features and Processes in v4.7.1 Incorporated instrumented models: DDM-3D, Sulfur Tacking, Primary Carbon Apportionment based on CMAQv4.7 science updates
