Abstract

Measurements of atmospheric sulfur dioxide performed during the Swedish expedition “Ymer80” in the Arctic are presented. Wet chemical filter sampling and subsequent chemiluminescence analysis enabled detection in the low pptv range. SO₂ mixing ratios between 5 pptv and 100 pptv were measured. SO₂ values over the closed ice sheet were usually lower than over the open ocean. Possible source and sink mechanisms are discussed. The influence of atmospheric transport is shown by trajectory analysis and helicopter ascents.
