The technical literature on air pollution dispersion is quite extensive and dates back to the 1930s and earlier. One of the early air pollutant plume dispersion equations was derived by Bosanquet and Pearson. Their equation did not assume Gaussian distribution nor did it include the effect of ground reflection of the pollutant plume. Sir Graham Sutton derived an air pollutant plume dispersion equation in 1947 which did include … WebAtmospheric dispersion modelling is an essential tool in determining the impact on air quality of a proposed or existing activity.

WebAir quality dispersion modeling utilizes mathematical formulas to characterize atmospheric processes that disperse a pollutant emitted by a source. Along with emissions, terrain, and/or meteorological inputs, a dispersion model is used to predict concentrations of a particular pollutant at receptor locations outside a facility’s fence line. WebJan 1, 2014 · Air dispersion is greatly affected by the interaction between atmosphere and the pollutant containing air parcel. Most commonly considered factors are wind, temperatures, and humidity. Less obvious, but equally important, are vertical motions that influence air parcel motion. Atmospheric stability affects the vertical motion of air parcels.
