Abstract
The article provides an overview of the systems for modeling the spread of pollutants, discusses their advantages and disadvantages. An approach to modeling the spread of pollutants in the atmospheric air of an urbanized area on the basis of the Calpuff software suite is proposed. The processes and sources of data on the terrain, meteorological parameters, etc., necessary for the generating concentration maps for Russian cities are described in detail. The approach consists of three main stages: modeling meteorological parameters, modeling pollution spread and visualization of the data obtained. An example of modeling of pollutants spread in the atmospheric air for Volgograd is given.
