Atmospheric Pollutant Dispersion Modeling Methods

Abstract

Abstract The method of modeling and simulating different phenomena in various fields of scientific knowledge is an essential part of many branches of science, each of which has specific types of models. Using mathematical methods, these models try to simulate a real situation by means of numerical analysis that describes the relationships between the characteristic quantities of air pollution phenomena, such as emissions, meteorology atmospheric concentrations of pollutants, deposition, and other factors. Air and water pollution measurements give information about the environmental concentrations of pollutants scattered by different sources but can only describe the phenomena involved qualitatively, at specific locations and times, without identifying the causes that lead to pollution problems. However, models of air and groundwater pollution can provide a deterministic description of the problems of air or water quality, including an analysis of the factors and causes of the pollution phenomenon (emission sources, meteorological processes and chemical and physical changes), and some guidance for implementing measures to mitigate these phenomena of environmental pollution. Due to the ability of these methods to establish the relative importance of relevant processes, they play an important role in current day science.
