The aim of this study is to provide a comprehensive review with regards to recent developments, major research, computational methods and air quality models applications. The development of models for air pollution assessment has been identified as an important area for future research. Air pollution due to massive use of motor vehicles in urban areas of India is one of the most serious and fast growing problem to solve. These motor vehicles emit significant quantities of CO2, CO, hydrocarbons, oxides of nitrogen, SPM and other toxic substances in the atmosphere which adversely affect the environmental and the health. The objective of this study is to understand the chemistry of air pollution with its precise estimation through modeling. The behavior and relation between emission and deposition of pollutants can explain with the help of air quality models. Modeling is a set of different scientific methods that are helpful to analyze nature and behavior of pollutants in the atmosphere. On the basis of source of pollutants air quality models are classified as point, area or line source models. Various Gaussian based line source models are commonly used in India to assess the impact of vehicular pollution along the roads or highways. Sources of air pollution, chemistry of pollutants and computational methods for dispersion modeling are discussed and reviewed with respect to various literature and corresponding methods. The paper includes comparative study of various air quality models and study of complex phenomenon of air pollution. Recent modified air quality models and their future scope are also discussed in the paper which help for scientists who work in the same field.
