Spatial distribution of the arctic haze aerosol size distribution in western and eastern Arctic

Abstract Since June 1993, four flight campaigns to the Arctic have been carried out by a group of scientists from Russia and Germany. Optical remote-sensing methods and in-situ chemical and aerosol measurements have been combined on board a Russian IL-18 research aircraft. From arctic air bases in Siberia, Alaska, Canada, and Spitsbergen, respectively, flights have been undertaken to determine spatial structure of arctic haze events. This paper reports on aerosol data obtained during the expedition of Spring 1994. Haze events have been found in the east and west Arctic, containing about the same concentration of particles. Horizontal and vertical layer extensions are given and the size dist…
