Abstract

The study presents the data on the concentrations of chemical components measured in aerosol samples collected during the IAO complex atmospheric radiation experiment (organized by the V.E. Zuev Institute of Atmospheric Optics) carried out in December 22, 2015. Their vertical distributions derived from the sampling data performed with the use of “Optik” Tupolev-134 aircraft laboratory are reported. Both parts of the experiment were conducted on the same route over background areas of Tomsk and Novosibirsk regions in the daytime. General time duration of the flight was about 3,5 hours. Sampling was carried out on both routes onto Petryanov’s filters AFA-HP-20 in the following troposphere layers 7000-5500, 4000-3000, 2000-1500 and 1000-500 m. The differences in concentrations of carbon-free inorganic ions and chemical elements in the aerosols on the Tomsk and Ordynskiy routes are discussed in the paper. An altitudinal distribution of inorganic ions in both areas is very similar only for one ion - SO₄ ^2-. The top layer is characterized by the smallest differences in the concentrations of the other components under consideration, and even almost complete coincidence of the total concentration of ionic macro components for both sensing areas. The trend in the vertical distribution of elements stored for 2/3 of them like ionic component. As many ionic components in the Tomsk region of sensing we observed inverse nature of the distribution of a large part of the element concentrations in the middle layers.
