POLARCAT-France
Kangerlussuaq, June/July 2008



POLARCAT-France is a part of the international project POLARCAT, in the framework of the International Polar Year. During the POLARCAT-France summer campaign, aircraft based measurements are performed out of Kangerlussuaq, Greenland (67°00′38″ N, 50°42′33″ W), with the objective to investigate the pollutant transport pathways to the Arctic, with respect to European outflow, Canadian and Siberian boreal forest fires.
The French ATR aircraft is equipped with various in-situ aerosol instrumentation, an ozone lidar, an aerosol lidar as well as CO and O3 trace gas measurements. In parallel, the German Falcon of DLR will perform the project POLARCAT-GRACE at Kangerlussuaq. If possible, flights will be coordinated. Furthermore an intercomparison flight with the NASA DC-8 (ARCTAS) is planned.
