Abstract
A model based on a substance transport equation for the reconstruction of polydisperse substance fallout from a continuous high-altitude source is proposed. The model is put to an evaluation test with field and laboratory data on benzoperin pollution of snow cover in the vicinity of Power Station-3 in the city of Barnaul. The effects of wind direction changes in the atmospheric boundary layer on the formation of long-term aerosol substance fallout are estimated.
