The period of highestfire activity (August 2017) by the radiation power and the number of fires for the period since 2007 to 2019 was revealed. Based on image processing techniques in the infrared range (on a 4 μm channel) according to MODIS and VIIRS data the statistical analysis of fire data was carried out and variations in the radiation power from fires were studied. The main optical and microphysical characteristics of the atmospheric aerosol for the periods with the largest number of fires for the Black Sea region wereanalyzed. A comprehensive analysis of the main optical characteristics variability and precipitation samples for periods of special fire activity was carried out. Considering that nitrogen oxides enter the atmosphere as a result of combustion processes, an analysis of atmospheric precipitation samples for the content of nitrates for days with the maximum number of thermoactive points according to satellite data was carried out in order to identify a possible correlation.
