Chemistry of Aerosols in the North Slope of Alaska: ISDAC 2008 study.
EMSL Project ID
30423
Abstract
The ISDAC (Indirect and Semi-Direct Aerosol Campaign) field study carried out in the North Slope of Alaska 2008 was a collaborative effort sponsored by the DOE Atmospheric Radiation Measurement (ARM) Program and the National Research Council of Canada. The study was focused on obtaining detailed measurements of the radiative, physical, and chemical properties of aerosols and clouds using instrumentedaircraft. Ending its mission with a final flight on April 30, 2008, the research aircraft completed 27 science flights in the region around the North Slope of Alaska. These flights included several golden cases where both cloud and
aerosol measurements and sampling were performed above, within, and below mixed-phase cloud layers. During this mission there were several periods where an absorbing layer of aerosols, commonly called Arctic Haze was
observed. Samples collected during these time periods will be examined to assess the types of carbonaceous aerosols involved in the formation of Arctic haze. This proposal seeks to employ an array of EMSL hosted analytical methods for chemical and microscopy characterization of aerosol samples collected during the ISDAC study.
