Numerical modeling of minor gas constituents and aerosols in the atmosphere

In this paper, the structure of meso- and regional-scale atmospheric models is briefly described. The models incorporate transport of multicomponent pollutant transport/transformation and aerosol formation through nucleation, condensation-evaporation, and coagulation mechanisms. Also, an optimization problem is considered aimed at minimizing the emission source magnitudes. The results of numerical experiments are presented for a number of applications to demonstrate the model capabilities in solving environmental problems for different areas. Analysis of the numerical results shows that the models developed can be successfully used for solving regional environmental problems. (C) 2004 Elsevier B.V. All rights reserved.
