Paper Abstract

The results of the round-the-clock measurements of the size distribution of equivalent black carbon in the near-ground submicron aerosol of Western Siberia in 2014-2016 are analyzed. The results were obtained with the diffusion BC spectrometer developed by us. It was found that, in the approximation of unimodal lognormal function, the annual dynamics of the monthly average BC size distributions is characterized by the year-to-year stability and shows winter maxima and summer minima of the BC volume median diameter and the distribution amplitude. The BC median diameter varies from 140 to 220 nm, and the distribution amplitude ranges from 0.4 to 3.4 μm3/cm3. A significant increase in the diurnal average values of the BC median diameter was observed under conditions of income of smokes from forest fires to the measurement site.
