Features of spatial distribution of aerosol characteristics over Arctic seas

摘要

Based on data of seven expeditions, we considered the specific features of the spatial distribution of aerosol physicalchemicalcharacteristics over Arctic seas in Russia. It is shown that the average aerosol and black carbon concentrationsand aerosol optical depth of the atmosphere decrease by a factor of 2-2.5 in the direction from west to east. A moredetailed analysis in the sectors of the Barents and Kara Seas revealed a tendency toward a decrease in aerosolcharacteristics in the northeast direction. We noted that the average ion concentrations in aerosol composition are closein value over the Barents and Kara Seas. Continental and maritime sources make nearly identical contributions to ioncomposition of aerosol over these seas.
