What is AERMOD?

AERMOD (American Meteorological Research and Development Model) is a steady-state plume dispersion model developed by the U.S. Environmental Protection Agency (EPA). It is used to assess air pollutant concentrations from a variety of sources, particularly industrial facilities. AERMOD incorporates air dispersion based on planetary boundary layer turbulence structure and scaling concepts, including treatment of both surface and elevated sources, and both simple and complex terrain. It is commonly used for regulatory air quality modeling applications, such as permitting and compliance demonstrations.
