Abstract Determinations of atmospheric sulfur dioxide were made across the North American Aretic using gas chromatography with a detection limit of 25 parts per trillion by volume and a precision of 25% or better. The vertical distribution of sulfur dioxide in the Arctic atmosphere in April, 1986 was highly variable, with concentrations ranging from the detection limit to 15 parts-per-billion by volume (ppbv). While SO2 exceeded 10 ppbv in an exceptional haze layer in the Alaskan Arctic, sulfur dioxide was sometimes in the 1 – 5 ppbv range when the haze was absent. This was particularly true for the Canadian Arctic in the vicinity of Alert. In the lower stratosphere over Ellesmere Island, sulfur dioxide was 0.85 ppbv.
