Abstract

We discuss how the Arctic atmosphere is affected by the long-range transports of continental aerosol: smokes from forest fires, associated gas combustion products, and anthropogenic pollutants. The analysis was carried out using measurements of the aerosol optical depth of the atmosphere and the aerosol and black carbon concentrations in 15 marine expeditions. Data from trajectory analysis of air mass motion, satellite maps of thermal anomalies, and coordinates of the main sources of anthropogenic emissions were used to identify the sources of the strongest pollutions of the Arctic atmosphere. We present the statistical estimates of the relative contributions from three types of continental pollutants into the atmosphere of the Eurasian sector of the Arctic Ocean.
