The elemental composition of aerosol in the atmosphere of the research station Ice Base “Baranov Cape” based on 2017- 2020 measurements was studied. The elements, most prevalent in the earth’s crust, dominate in the composition of aerosol. The seasonal and annual variability of the concentrations of elements in the composition of aerosol is shown. During the summer and spring periods, the concentrations of Li, Cd, As, V, Cj, Sb, Sn, Se, Pb, B, Tl, U, Be, Th, Ag, and W increase multiple times.
We discuss the measurements of aerosol optical depth (AOD) of the atmosphere and aerosol (NA) and black carbon (MBC) concentrations in 2018-2019 at two Arctic stations: Barentsburg (Archipelago Spitsbergen) and “Cape Baranov” (Archipelago Severnaya Zemlya). The average aerosol characteristics at “Cape Baranov” had been: AOD (0.5 μm) = 0.11, NA= 5.24 cm-3, MBC = 47 ng/m3 in 2019; and AOD (0.5 μm) = 0.07, MBC= 68 ng/m3 in 2018. The aerosol characteristics in Barentsburg, on the average, have larger values: AOD (0.5 μm) = 0.12, NA= 6.09 cm-3, MBC = 91 ng/m3 in 2019; and AOD (0.5 μm) = 0.087, NA = 6.54 cm-3, MBC= 109 ng/m3 in 2018.
