EPA Releases Updated CMAQ Air Model Version 6.0 for State Air Quality Planning
WASHINGTON — The U.S. Environmental Protection Agency on October 19 released version 6.0 of its Community Multiscale Air Quality (CMAQ) model. The agency said the update adds upgraded chemical mechanisms, global-to-local scaling, enhanced source and region tracking and faster processing, helping state, local and tribal partners prepare State Implementation Plans and attainment planning under the National Ambient Air Quality Standards (NAAQS). CMAQ is the EPA's core model for simulating how pollutants such as ozone and particulate matter form and move, and the update affects the technical basis of air quality planning nationwide.
