Seasonal and interannual variations of aerosol characteristics in the Arctic settlement Barentsburg (Spitsbergen archipelago, 2011-2017)

Based on data of 7-year (2011-2017) measurements in the Arctic settlement Barentsburg (Spitsbergen archipelago), we discuss the seasonal and interannual variations in aerosol characteristics: atmospheric aerosol optical depth and nearground concentrations of aerosol, absorbing substance (black carbon), ions, as well as gas-phase species. For certain aerosol characteristics (especially in 2011 and 2012) we noted an anthropogenic effect of settlement, i.e., dust, black carbon, and pollutants from heat and power plant.
