In this work, a numerical estimate of the average field of the mass concentration of PM2.5 aerosol particles for the European part of Russia was obtained using the numeric technology of fluid-location of the atmosphere (FLA). Atmospheric aerosol concentrations reconstructed based on satellite lidar measurements were used as input information for the first time. According to the modeling results, the areas of the increased PM2.5 mass concentrations were observed over Krasnoyarsk Krai in the summer period of 2021. The results were compared with the spatial distribution of the surface PM2.5 mass concentrations derived from the second Modern-Era Retrospective analysis for Research and Applications (MERRA-2). © 2023 SPIE.
