International Polar Year Field Campaign to Study Effect of Aerosols on Arctic Clouds and Climate (March 08)


During April 2008, researchers will descend on and above Barrow, Alaska, to obtain data from the atmosphere that will help them understand the impacts of aerosols on Arctic clouds and climate as part of the International Polar Year. The Indirect and Semi-Direct Aerosol Campaign, or ISDAC, which is jointly sponsored by the U.S. Department of Energys Atmospheric Radiation Measurement (ARM) Climate Research Facility, the National Research Council of Canada, and Environment Canada, includes an airplane equipped with more than 40 instruments to measure cloud and aerosol properties in the sky over the Arctic, while surface-based instruments at ARM sites in Barrow and Atqasuk, Alaska, are obtaining measurements from the ground.
