Description
Description: Joint Center for Environmental Technology UMBC, Baltimore, MD, USA. We present analysis of simulations using the NASA GEOS-5 chemistry and transport model to quantify contributions from different continents to the Western Arctic pollution, to investigate pollution sources and to identify transport pathways. We compare DC-8 airborne measurements of CO, SO2, BC and SO4 from the NASA Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) field campaigns (spring and summer, 2008) and observations from the AIRS instrument on NASA's Aqua satellite to demonstrate the strengths and limitations of our simulations and to support this application of the model. Comparisons of measurements along the flight tracks with regional averages show that the along-track measurements are representative of the region in April but not in July. Our simulations show that most Arctic pollutants are due to Asian anthropogenic emissions during April. Boreal biomass burning emissions and Asian anthropogenic emissions are of similar importance in July. European sources make little contribution to pollution in the campaign domain during either period. The most prevalent transport pathway of the tracers is from Asia to the Arctic in both April and July, with the transport efficiency stronger in spring than in summer.
