Abstract:

The given study presents the results of spatiotemporal variability of aerosol deposition flows in the cold period for two background monitoring stations of IAO SB RAS, i.e., Akademgorodok and the reference one (the Kireevsk village, 60 km from Tomsk). Methods of stereoscopic binocular microscopy, X-ray structure, and instrumental neutron activation analysis were used when studying the mineral-matter and geochemical compositions of snow solid sediment samples. At the same time, the concentrations of submicron aerosol and soot in the surface air have been measured at the aerosol station of IAO SB RAS from November, 2005 to April, 2006. The differences in mineral-matter and geochemical compositions of snow solid sediment samples in two measurement points are revealed. An excess of aerosol flow values in Akademgorodok over those in the Kireevsk village is shown. A steady tendency to the decrease of the values of aerosol deposition flows in snow and concentrations of submicron aerosol and soot are established in the surface air in Akademgorodok when passing from winter to spring seasons.
