Abstract
The article presents statistics on the distribution of aerosol particles during the summer vegetation and winter dormancy of woody plants at the size Fonovaya observatory of the IAO SB RAS (Tomsk Region) from July 1, 2022, to June 30, 2023. The analysis of the ratios of aerosol fractions revealed a paradoxical situation, where the count concentration of aerosol particles 0.3-2.0 mm diameter turned out to be significantly higher in winter than in summer. A phenomenological model is suggested which describes this effect as a manifestation of the action of radiometric forces.
