ARCTAS: Arctic Research of the Composition of the Troposphere from Aircraft and Satellites  ( Spring & Summer 2008 )

The arctic troposphere in Winter and Spring is heavily polluted by long-range transport from northern mid-latitudes. This pollution has a number of environmental consequences. Radiative forcing from thick aerosol layers ("arctic haze") and black carbon deposition on snow modify both the regional and global climates.

Large uncertainties remain regarding the transport pathways from mid-latitudes to the Arctic, and the relative contributions of different source regions to arctic pollution. Integration of satellite and aircraft observations with models through ARCTAS will address this issue.   [Read More.]
