The Community Multiscale Air Quality Modeling System (CMAQ) Version 5.4 Webinar Archive

This Webinar, recorded January 18th, provides an overview on the Community Multiscale Air Quality (CMAQ) Modeling System, EPA ’s premier modeling system for studying air pollution from global to local scales. For nearly a quarter century, EPA, states and tribes have used CMAQ to support air quality management. CMAQ is continually updated to incorporate new knowledge on the state-of-the science to provide a powerful computational tool for translating fundamental atmospheric science principles to policy scenarios. This webinar focuses on CMAQ version 5.4 (CMAQv5.4), publicly released in October 2022.
