Comparison of aerosol characteristics at polar stations Cape Baranov and Barentsburg in measurement seasons of 2018-2019

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.
