Analysis of aerosol transported to the Arctic based on LaMP's airborne measurements (ATR-42) during the POLARCAT project
The aims of this thesis were, in a first step, to build a climatology of pollution plumes transported from source continents to the Arctic as measured during the POLARCAT-France campaigns performed in spring and summer 2008, in the frame of the 4th International Polar Year. The climatology is includ...
