Calculations of the state of air pollution were carried out using a mathematical model of the transfer of harmful impurities in the upper layer of the atmosphere. Numerical schemes of the model of the transfer of harmful impurities in the baroclinic atmosphere have been developed. With the help of these studies, quantitative calculations of the transfer of harmful substances in the upper layer of the atmosphere were carried out, taking into account the impact on the Earth's surface. Geoecological maps of the spread of harmful impurities in inversion conditions have been compiled. The distribution of impurities in stable atmospheric conditions was carried out for two variants: in the first case, the wind speed on the Earth's surface was chosen equal to 2 m/s, and in the second-4 m/s. The calculation time corresponded to the period of full ventilation of the field area with a length of about 40 km. Along with the known dangerous weather conditions that occur during inversions and their quiet combination, it has been established that the most dangerous are the established weather conditions.
