Abstract

Based on multiyear (2007-2022) model MERRA-2 reanalysis data, we analyze the seasonal variations in the content of absorbing substance (black carbon) in Eurasian sector of the Arctic Ocean. Average concentrations of black carbon over six Arctic seas (from the Greenland to Chukchi Sea) are presented for different months. We discuss the specific features of latitudinal and longitudinal distribution of the black carbon concentrations in separate periods of the year. It is noted that model data show no winter-spring maximum and overestimate the summertime concentrations in the Asian sector of the Arctic Ocean.
