In the context of this "Air Dispersion Modeling" section, air dispersion models may be defined as computerized mathematical calculations for predicting the dispersion behavior of air pollutants emitted into the atmosphere. The many types of air dispersion models include those for modeling: the continuous emission of buoyant pollutant plumes; the non-continuous accidental releases of either buoyant or heavier-than-air (i.e., dense gas) pollutants; puff emissions; point-source emissions; area-source or line-source emissions; mobile transportation-source emissions; fire and smoke emission models; etc. Air quality models for urban airsheds are probably best placed in the "Air Quality" section rather than in this "Air Dispersion" section.

- Wikipedia: Atmospheric dispersion modeling is the mathematical simulation of how air pollutants disperse in the ambient atmosphere. It is performed with computer programs that include algorithms to solve the mathematical equations that govern the pollutant dispersion. The dispersion models are used to estimate the downwind ambient concentration of air pollutants or toxins emitted from sources such as industrial plants, vehicular traffic or accidental chemical releases. They can also be used to predict future concentrations under specific scenarios. Therefore, they are the dominant type of model used in air quality policy making. They are most useful for pollutants that are dispersed over large distances and that may react in the atmosphere. For pollutants that have a very high spatio-temporal variability and for epidemiological studies statistical land-use regression models are also used.
