The purpose of this study is to create a software-analytical complex, which allows forecasting the state of the environment, taking into account all major climatic and landscape factors. The complex includes a mathematical model, which can be linked to specific man-made territories, and a database of modern disasters of natural and man-made nature. A set of programs for precise solution of the problem on the transfer and deposition of pollutants in the atmosphere, taking into account the heterogeneity of atmospheric properties by height and properties of the underlying surface, some blocks of the simulation mathematical model of the behavior of pollutants, taking into account the specific geographic location of the territory and a complex of information support for the model were developed.
