Air Dispersion Modelling predicts how pollutants are dispersed in the atmosphere from different pollution sources taking into account building influences, topography, meteorology, downwind distances, and other factors. Air Dispersion modelling is a mathematical simulation of how air pollutants disperse in the ambient atmosphere. The simulation uses mathematical equations and algorithms to characterize the atmospheric processes that distribute an air pollutant emitted by a source over a wide area. These models are used to estimate or to predict ground level concentrations (GLC) at selected downwind receptor locations of air pollutants emitted from sources such as industrial plants, mines, vehicular traffic or accidental chemical releases.

CALINEpro is based on steady-state Gaussian plume models specifically designed to calculate air quality impacts from vehicle emissions near highways. Given source strength, meteorology and site geometry, the model can predict pollutant concentrations for receptors located within 500 meters of the roadway. It also has special options for modelling air quality near intersections, bridge and parking facilities.
