Abstract
Abstract—
Based on the results of a comprehensive experiment conducted in September 2020, the spatial distribution of the following trace gases over the seas of the Russian Arctic are analyzed: carbon monoxide (CO), ozone (O3), nitrogen oxide and dioxide (NO and NO2), and sulfur dioxide (SO2). It is shown that the gas concentrations in the surface air layer over the seas (at an altitude of 200 m) vary in the range 18–36 ppb for O3, 60–130 ppb for CO, 0.005–0.12 ppb for NO, 0.10–1.00 ppb for NO2, and 0.06–0.80 ppb for SO2. The distribution of the gases over the water area is heterogeneous over most seas, which most likely reflects differences in their uptake by the ocean and peculiarities of transport from the continent.
