The influence of tropical and subtropical air masses on the chemical composition of the tropospheric aerosol of Western Siberia based on the results of systematic aircraft sounding in 1997-2017
No full textAlmost monthly sensing of the troposphere from 500 to 7000 m above Karakansky bor (Novosibirsk Province) are conducted since 1997 up to now by using of the aircraft-laboratory "Optik" based on Antonov-30 or Tupolev-134. Aerosol sampling on to Petryanov filters AFA-CP-20 for subsequent laboratory quantitative analysis of the content of inorganic ions and the next elements in the aerosol composition: Al, Ba, Ca, Cu, Fe, Mg, Mn, Mo, Ni, Pb, Sn, Ti, V, Be, Cd, Si, Co, Cr, Sr, Zn, Zr was performed for each flight. For the region of the study of tropospheric aerosol, the chemical composition of the aerosol was classified for the main air masses during the period of airborne sounding from September 1997 to June 2017 - continental arctic, continental moderate, and combined into one “southern” group of the continental tropical and subtropical air masses. Explicit "southern" origin, along with silicon, have chromium, manganese, silver and bicarbonate-anion. To the same group, the ions of chlorine and sodium are attracted, which probably were transported together with salt particles originating from Central Asian deserts.</jats:p

No full text&lt;p&gt;Aerosols play an important role in radiation processes in the atmosphere, as well as they have a significant impact on global and regional air quality. The process of the atmospheric nanoparticle formation starts from in situ conversion of condensable vapors. Then, the freshly formed nanometer-size clusters begin to grow due to the condensation of nucleating vapours on them and a self-coagulation as well, thus reaching the optically active size ranges. The relative contribution of the above mechanisms can be estimated by the chemical composition of size-segregated particles. Here, we present preliminary results of the analysis of aerosol samples characterizing the inorganic chemical composition of particles ranging from a few nm to 10 mm. The sampling was performed at Fonovaya Observatory (West Siberia) in October 2021 by means of the Model 125R Nano-MOUDI Impactor.&lt;/p&gt;&lt;p&gt;The analysis showed that in the lowest size range (&lt;10 nm), only five ions were detected: SO&lt;sub&gt;4&lt;/sub&gt;&lt;sup&gt;2-&lt;/sup&gt;, Cl&lt;sup&gt;-&lt;/sup&gt;, K&lt;sup&gt;+&lt;/sup&gt;, Na&lt;sup&gt;+&lt;/sup&gt;, H&lt;sup&gt;+&lt;/sup&gt;. The growth of the nucleation mode particles to the size range of 60-100 nm was accompanied by increasing content of SO&lt;sub&gt;4&lt;/sub&gt;&lt;sup&gt;2-&lt;/sup&gt;, Na&lt;sup&gt;+&lt;/sup&gt;, H&lt;sup&gt;+&lt;/sup&gt; ions to 50, 37 and 13%, respectively, suggesting the condensation of H&lt;sub&gt;2&lt;/sub&gt;SO&lt;sub&gt;4&lt;/sub&gt; vapours or the coagulation of particles contained mainly Na&lt;sub&gt;2&lt;/sub&gt;SO&lt;sub&gt;4&lt;/sub&gt;. A content of ammonium ions (NH&lt;sub&gt;4&lt;/sub&gt;&lt;sup&gt;+&lt;/sup&gt;) appeared to be significant only in the accumulation mode size range (0.1-1.0 mm). Nitrates (NO&lt;sub&gt;3&lt;/sub&gt;&lt;sup&gt;-&lt;/sup&gt;) were detected mainly in the Aitken mode particles and then their contribution increases in accumulation and coarse mode ranges.&lt;/p&gt;&lt;p&gt;This work was supported by the RFBR grant No. 19-05-50024 (Microparticles in the atmosphere: formation and transformation in the atmospheric surface layer and in the free troposphere, radiation effects and impact on public health).&lt;/p&gt;</jats:p
