"Arctic pollution: early results from the ARCTAS aircraft mission"

The NASA ARCTAS aircraft mission was conducted in spring-summer 2008 to investigate the sources, transport, and chemical evolution of Arctic pollution, the implications for radiative forcing of climate, and the role of boreal forest fires. I will present results from ongoing work at Harvard to interpret the ARCTAS observations for better understanding of Arctic atmospheric composition. Topics will include (1) long-range transport of pollution, (2) sources, composition, and evolution of the aerosol, (3) radical photochemistry, (4) sources of methane, and (5) sources and fate of mercury.
