Mathematical modeling of urban air pollution. General theory

Abstract

The fundamental theory of urban air pollution modeling is developed. A number of points are considered including: The definition of the mean and random components of the wind velocity field, the necessary conditions for obtaining conventional Eulerian and Lagrangian models, the proper inclusion of nonlinear chemical reactions in a model, the nature of the spatial and temporal averages implicit in the computed concentrations, and the requirements for simulating photochemical smog formation in an urban area.
