Estimation of gas and aerosol concentrations with data of measurements in southern Baikal

On the basis of the asymptotic of solutions of the turbulent diffusion equation, models are proposed for estimating the concentration fields of sulfur dioxides, nitrogen, and submicron fractions of aerosol particles from measurements in the village of Listvyanka at the EANET station. The most significant sources of these impurities are large thermal power plants located in the cities of Irkutsk, Angarsk, Shelekhov. The main attention is paid to the analysis of episodes of the passage of the CHPP smoke plumes through the observation point. Measurement data from meteorological and aerological stations are used as additional information. For the territory of South Baikal, the results of the numerical reconstruction of concentration fields and the estimation of the transformation parameters of pollutants from remote sources are presented.
