Description
Summary:Routine aerosol sampling at Barrow and Fairbanks continued. The basic four-year record of certain constituents in the Barrow aerosol showed distinct and reproducible seasonal variations. Cascade-impactor samples from Barrow and Europe were taken and analyzed for sulfate and trace elements. S02 at Bear Island during winter was found to be highly pulsed and associated mainly with cyclonic trajectories from eastern Europe and the USSR. On the basis of a wide variety of indirect meteorological and chemical evidence, Eurasia was strongly suggested to be the major source of Arcitic haze, with North America contributing only occasionally. Aerosol sampling at Iceland continued. A cooperative European Aerosol-Sampling Network was established and has proved highly successful. The hypothesis of the Eurasian source of Arctic haze was confirmed by the noncrustal Mn/V ratio, the first regional tracer for pollution aerosol; the dominance of Eurasian sources was further confirmed by a much more sophisticated seven-element tracer system which proved capable of discriminating among regional aerosols in Europe North America. Papers from the Second Symposium on Arctic Air Chemistry were published in a special issue of Atmospheric Environment (8/80); plans for the second symposium were made. A cooperative study with W. Berg of NCAR on Arctic bromine was begun.
