AERMOD is an air dispersion model that is widely used to estimate air pollutant concentrations near the ground level. It is a steady-state Gaussian plume model that takes into account a variety of factors such as meteorology, topography, and land use to predict the dispersion of air pollutants from a point source. AERMOD is widely used in regulatory air quality modeling and is accepted by the United States Environmental Protection Agency (EPA) as the preferred regulatory air dispersion model for most applications. this Vedieo shows how to create Airqulity of the study area
