The concept and implementation of a numerical dispersion model will be discussed. The use of an advection-diffusion-reaction equation, rather than a simplified Gaussian pollution model, allows flexibility with atmospheric variables and avoids some of the simplifying assumptions of the Gaussian model. This finite difference model looks at atmospheric processes such as advection, diffusion, chemical reactions and removal processes that dictate the evolution of a plume of air pollution. The physics of the model as well as the computational methods used to create the model will be covered. A variety of test cases will be presented to display how the model works under a variety of different atmospheric conditions.
