Comparison Of Aerosol Characteristics At Polar Station "Cape Baranov" And "Barentsburg" In Measurement Seasons Of 2018-2019

We discuss the measurements of aerosol optical depth (AOD) of the atmosphere and aerosol (N-A) and black carbon (M-BC) 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 mu m) = 0.11, N-A = 5.24 cm(-3), M-BC = 47 ng/m(3) in 2019; and AOD (0.5 mu m) = 0.07, MBC = 68 ng/m(3) in 2018. The aerosol characteristics in Barentsburg, on the average, have larger values: AOD (0.5 mu m) = 0.12, N-A = 6.09 cm(-3), M-BC = 91 ng/m(3) in 2019; and AOD (0.5 mu m) = 0.087, N-A = 6.54 cm(-3), M-BC = 109 ng/m(3) in 2018.
