POLARCAT - A unique snapshot of the Arctic Atmosphere

The results from the POLARCAT campaigns are coming forth. During the IPY Oslo Conference, we released a brochure summarizing some of the activities resulting from the campaigns. If you weren't able to get a hard copy, please download the PDF [here]. The brochure focuses to a degree on the Norwegian and European contributions, but also includes results from the NASA-ARCTAS and NOAA ICEALOT and ARCPAC campaigns. Also, don't miss the Atmospheric Chemistry & Physics Special Issue

The end of the International Polar Year and the Oslo Science Conference

The first session proposal for the 2010 Oslo Science Conference came in from Andreas Stohl of the Norwegian Institute for Air Research (NILU). He proposed an integrating session on "Short-lived pollutants in the polar regions: Sources, transport, impacts", together with Kathy Law, a colleague in France. Andreas and Kathy Law are co-leaders for the IPY project POLARCAT. [more information]

The workshop was hosted by the the Institute for the Study of Earth, Oceans and Space (EOS). Organizing bodies included the Norwegian Institute for Air Research (NILU) with sponsorship from the International Global Atmospheric Chemistry (IGAC) Program, the Clean Air Task Force (CATF), and the Taskforce on Hemispheric Transport of Air Pollution (HTAP) and iLEAPS. Funding was also provided by the Norwegian Research Council

    Abstracts at AGU

    There was a good showing of POLARCAT presentations at the Fall AGU in San Francisco this year (2008). To browse the submitted abstracts click here.

    Summer Campaigns Completed

    All field campaigns for the POLARCAT IPY program are finished. We will be posted results here as they become available. In the meantime, stay tuned.

    About the Program

    POLARCAT will execute a series of aircraft experiments at different times of the year in order to follow pollution plumes of different origin as they are transported into the Arctic and observe the chemistry, aerosol processes, and radiation effects of these plumes. It will also observe the atmospheric composition in relatively cleaner regions outside major plumes. The experiments will also take advantage of the long residence times of pollutants in the stably stratified Arctic atmosphere to study ageing processes by targeting air masses that have spent considerable time in the Arctic . The Arctic will, thus, also serve as a natural laboratory for investigating processes that cannot be studied elsewhere in such isolation.

    This is the POLARCAT portal. This site will be constantly changing throughout the IPY to address the activities associated with the individual campaign. Please bookmark this page and check back frequently for updates.
