Abstract
The paper considers variations in the chemical composition of the tropospheric aerosol over the background region of the south of Western Siberia in 1997 - 2019. Sounding of the troposphere from 500 to 7000 m above the Karakan pine forest (Novosibirsk region) with an almost monthly frequency is carried out from 1997 to the present using the Optic-E aircraft-laboratory based on the Antonov-30 until 2011 and the Tupolev-134 Optik in this decade. Aerosol sampling is performed at each height and in layers: 500-1000, 1500-2000, 3000-4000, 5500-7000 m onto Petryanov filters (AFAChP/ChA-20). Subsequent quantitative analysis for the content of ions and elements in aerosol matter was carried out at the Laboratory for Environmental Monitoring at Tomsk State University. Based on 1200 sample samples (until 2019), the annual cycle of the defined components was built. Their temporal and spatial variability is analyzed. The total variability of the concentration of the inorganic component does not exceed 2 orders of magnitude. Temporary variability of the concentration of trace elements can be more spatial, reaching 4 orders of magnitude. Some data are also presented on organic aerosol, an experimental study of which by the aircraft-laboratory began in the current decade.
