CMAQ Fact Sheet
For more than a decade, EPA and states have used EPA’s Community Multiscale Air Quality (CMAQ) Modeling System, a powerful computational tool for air quality management.
CMAQ brings together three kinds of models:
- Meteorological models to represent atmospheric and weather activities.
- Emission models to represent man-made and naturally-occurring contributions to the atmosphere.
- An air chemistry-transport model to predict the atmospheric fate of air pollutants under varying conditions.
In June 2017, EPA released the newest version of the modeling system —CMAQ 5.2. Learn more about CMAQ by clicking on the link to our fact sheet below.
