Bromine monoxide radical likely dominates dimethylsulfide oxidation before the springtime onset of Arctic ice melt

Abstract

To understand the atmospheric fate of dimethylsulfide (DMS) during the Arctic spring-to-summer transition and the onset of ice melt, we measured volatile methylated sulfur (VMS) species, including DMS and DMS-derived oxidation products, dimethyl sulfoxide (DMSO), and dimethyl sulfone (DMSO2), in the Fram Strait during May and June of 2023. Elevated DMSO contributions to VMS, depleted O3, high surface albedo, and air temperatures
