Abstract
The results of comparative studies of the ratio of aerosol fractions in the surface air and snow layers chronologically linked to stratigraphically significant snowfalls are presented. Probable paths of winter air masses were reconstructed using backward trajectories calculated with NOAA HYSPLIT_4 model and gridded meteorology NCEP/NCAR Reanalysis. It is shown that the features of the formation of the winter aerosol field within the Ob-Tomsk interfluve are mainly associated with winds with a southern component.
