Abstract
Sulfur dioxide concentrations were measured throughout the North American Arctic using gas chromatography with a detection limit of 25 ppt and a precision of 25% or better. The vertical distribution of SO sub(2) in the Arctic atmosphere in April 1986 was highly variable, with concentrations ranging from the detection limit to 15 ppb by volume. While SO sub(2) exceeded 10 ppb by volume in an exceptional haze layer in the Alaskan Arctic, the gaseous pollutant was sometimes in the 1-5 ppb by volume range when the haze was absent. With the observation of nearly 1 ppb by volume in the lower stratosphere over Ellesmere Island, Canada, there appeared to be an instance of LRT of volcanic SO sub(2) in the stratosphere or a chemical source for the pollutant.
