Representation of the Proper Semiempirical Model for Determination of Amount of Photochemical Smog in Mashhad

Simple models of photochemical air quality are necessary to represent raw guesses for photochemical smog amount. Semiempirical models have constant parameters which must be determined by using of the mathematical methods and local experimental concentrations of pollutants. These parameters are determined for Mashhad in this paper. The results of three models are compared with the existing experimental data. With respect to this comparison, it can be concluded that the model containing temperature parameter is the best model because the number of its. average bias and standard deviation is fewer than it of the other models, and also it predicts better the peak of ozone concentration arisen in midday.
