According to the developed requirements, a number of field experiments have been carried out to identify the parameters of models of the distribution of pollutants in the atmosphere from the emissions of energy objects. The results of experiments are analyzed and processed. 2. In the program-modeling system MathMapMod developed by authors, the automation module for the identification of parameters of models of pollutant emission distribution in the air from the emissions of energy objects has been improved, namely: mathematical methods of estimating the influence of the error of the determination of model parameters on the modeling result, the algorithm for reducing the dimension of the problem and algorithm of parallelization of calculations. This approach has allowed to significantly reduce the time of the decision of the identification task. 3. On the newly obtained results of experiments and with the help of the improved identification automation module, a more precise identification of the mathematical models of the distribution of pollutants in the atmospheric air developed by the authors was developed, which allowed reducing the modeling error to 5%. 4. An improved version of the MathMapMod system was tested by assessing the impact of atmospheric air emissions on the largest stationary man-made sources in Kyiv. A number of ecological maps of the distribution of the most dangerous chemicals in the surface layer of the atmosphere and risk maps for the population's health from such influence have been constructed. Also, the module for statistical analysis of atmospheric air monitoring data, system database, block of presentation of results was perfected. The system's capabilities are also demonstrated in forecasting the level of technogenic loading on the atmosphere from the emissions of the most powerful sources of atmospheric pollution in Kyiv for up to 7 days. The prediction error was not more than 10%, which is perfectly acceptable for such tasks. 5. Potential users for a faster mastering of the system MathMapMod developed a suitable method for its use.
