Submicron Aerosol and Black Carbon in the Troposphere of Southwestern Siberia (1997–2018)

Based on the multiyear measurements in surface atmospheric layer (from five stations) and regular flights of aircraft laboratory over background region Southwestern Siberia, compositions mass concentrations submicron aerosol absorbing substances (soot black carbon) are analyzed. The annual average carbon were found to be maximal 1997, 2012, 2016, when largest numbers wildfires occurred across entire territory Siberia. No significant, unidirectional trend interannual variations concentration particles was observed, while substance reliably decreased by 1.5% each year. To estimate effect urban pollutants, at Aerosol Station (in suburban Tomsk) compared those Fonovaya Observatory region). It shown that contribution anthropogenic sources observed winter season, minimal difference warm period seasonal behavior elemental three stations Novosibirsk Oblast almost completely matched dynamics atmosphere Tomsk Oblast. Data sensing troposphere Siberia (2000–2018) used determine values vertical distribution altitude range 0.5–7 km for season. altitudes km, there no trends aerosol; however, an increase all with a positive 5.3 ± 2.2% per year 1.5 significant p-value = 0.05.
