Estimates of interannual variations in aerosol characteristics over the Eastern Atlantic and South Ocean

Based on multiyear (2004-2018) studies of atmospheric aerosol on the route of the Russian Antarctic expeditions (from English Channel to Antarctica), we analyze the specific features of interannual variations in aerosol optical depth of the atmosphere and aerosol and black carbon concentrations in four latitude zones of the Eastern Atlantic (25°N – 60°N, 20°N – 0°, 5°S – 33°S, and 40°S – 63°S). Data on interannual variability ranges of aerosol characteristics in different zones and trend estimates are presented.
