Numerical simulations of the atmosphere play a critical role in reaching a more complete understanding of the atmosphere. Atmospheric dispersion modeling is the mathematical simulation of how air pollutants disperse in the atmosphere and to gain insight into the possible environmental impacts. There are two types of methods, analytical & numerical, to modeling the flow and concentrations of pollutants in the atmosphere. Analytical models, while are easier to understand and solve, rely on significantly simplifying assumptions. In order to further improve physics, numerical models are used to model more realistic real world situations such as uneven terrain and obstructions in urban areas, for example buildings, by incorporating these in the domain. The differential equations an air pollution model uses, such as convection-diffusion-reaction equations, require computational techniques such as finite differences to solve.
