Abstract
The process of the formation of a plume of NO2 emitted into the atmosphere by a point source is considered with the use of a new method for reconstructing NO2 distribution fields in the troposphere from GSA Resource-P satellite data and mathematical simulation. The functional form of the model is ascertained, which agrees in complexity with the amount of available experimental information. The values of the model parameters are found. The emission power is calculated. The reliability of the simulation results is estimated from the comparison of the calculations with the experimental data on the distribution of the altitude-integral amount of NO2 in air depending on the horizontal coordinates.
