Recent Enhancements to the Community Multiscale Air Quality (CMAQ) Modeling System

The Community Multiscale Air Quality (CMAQ) Modeling System is a comprehensive state-of-the-science air pollution modeling system that is widely used worldwide to study local to hemispheric air pollution issues and guide development of air pollution abatement strategies. For over two decades, EPA and states have used CMAQ to support air quality management. CMAQ is continually updated to incorporate knowledge on the state of the science and harness increased computing power in order to more effectively and efficiently characterize air quality and protect human health. Newer versions of the modeling system are publicly released on a periodic basis. CMAQv5.3 is scheduled for public release in summer 2019.
