CAMx v5.40 is now available for download
The Comprehensive Air quality Model with extensions (CAMx) is a publicly available open-source computer modeling system for the integrated assessment of gaseous and particulate air pollution. Built on today’s understanding that air quality issues are complex, interrelated, and reach beyond the urban scale, CAMx is designed to
- Simulate air quality over many geographic scales
- Treat a wide variety of inert and chemically active pollutants:
- Ozone
- Inorganic and organic PM2.5/PM10
- Mercury and toxics
- Provide source-receptor, sensitivity, and process analyses
- Be computationally efficient and easy to use
The U.S. EPA has approved the use of CAMx for numerous ozone and PM State Implementation Plans throughout the U.S, and has used this model to evaluate regional mitigation strategies. See the Overview page for more information on CAMx applications in the U.S. CAMx is also used throughout the world to support a wide variety of research and regulatory activities.
CAMx is written in Fortran and is designed for platforms running Unix/Linux, including Apple Mac OSx. The build scripts provided with CAMx do not support Windows/DOS.
