Pollution transported to the Arctic during the POLARCAT-France spring and summer campaigns: source regions and aerosol properties

Within the frame of the POLARCAT-France campaign, part of the 4th International Polar Year, the French research aircraft ATR-42 was deployed at Kiruna, Sweden and Kangerlussuaq, Greenland in April and July 2008, respectively. The aim of the campaigns was to characterise pollution plumes of different origins as they are transported to the Arctic. This study is focusing on the physical, chemical and optical properties of aerosol particles transported to remote Arctic regions.
