AERMOD has a wide range of applications in air quality management, including:

Eventually, the freedom fades, and the next project email arrives. The terrain files will need processing. The wind data will need quality assurance. But for a brief, shining interim, the air is just air again. It is ungridded. It is unmodeled. It is free. aermod free

The air is never empty. To the layperson, it is space; to the regulator, it is a spreadsheet; to the AERMOD model, it is a turbulent, three-dimensional chess board of meteorology and terrain.

All executables run on Windows (command prompt) and Linux. Source code (Fortran) is also available for transparency. | Aspect | Free Implementation | Commercial GUI

: A limited but free version of their professional interface.

: Free utilities like BPIPPRM (building downwash) and AERMET (meteorological data). But for a brief, shining interim, the air is just air again

For users uncomfortable with command-line interfaces, several free or open-source GUIs wrap the free AERMOD executable:

While many commercial software packages wrap the model in a fancy interface for thousands of dollars, the core engine is actually available at no cost. The Best Ways to Access AERMOD for Free

For formal permit applications (e.g., Title V, PSD), the free AERMOD is fully acceptable as long as input files are properly documented. No commercial interface is required by the EPA. However, consultants often prefer commercial tools for efficiency and audit trails.
