Abstract
During winter when the polar oceans are frozen, air masses entering Alaska from the Arctic are charged with suspended submicrometre particles whose chemical signatures show evidence of being derived from man-made sources of pollution1–3. Occasionally, the aerosol loading is large enough to reduce visibility and thus the phenomenon has come to be referred to as ‘Arctic haze’. We report here three strong episodes of Arctic haze in Alaska which were examined during February–April 1982 and which were found to be possibly associated with air emissions in central Eurasia.
