Description
Summary:Abstract. In spring 2006 a special meteorological situation occurred in the European Arctic region giving record high levels of air pollution. The synoptic situation resulted in extensive transport of pollution predominantly from agricul-tural fires in Eastern Europe into the Arctic region and record high air-pollution levels were measured at the Zeppelin ob-servatory at Ny-Ålesund (78◦54 ′ N, 11◦53 ′ E) in the period from 25 April to 12 May. In the present study we investigate the optical properties of the aerosols from this extreme event and we estimate the radiative forcing of this episode. We examine the aerosol optical properties from the source region and into the European Arctic and explore the evolu-tion of the episode and the changes in the optical proper-ties. A number of sites in Eastern Europe, Northern Scan-dinavia and Svalbard are included in the study. The obser-
