We identify pollution transport events during the spring phase of ARCTAS using CO from DC-8 observations, AIRS satellite data, ground-based data at Eureka, and GEOS-Chem model simulations. We find that for most events, AIRS is able to quantitatively observe pollution transport to the Arctic from a v...

We find that for most events, AIRS is able to quantitatively observe pollution transport to the Arctic from a variety of different source regions, including North American, Asia, and Siberia. Using tagged tracer simulations, we find major contributions to Arctic CO from agricultural burning in Siberia, although 2008 Siberian fire counts were not anomalously high [NASA, 2008]. Southeast Asian fires were less significant. Midlatitudes pollution contributed to polar background concentrations. • GEOS-Chem CO sampled along the DC-8 flight track shows a consistent overestimate relative to in-situ observed CO during the ARCTAS flights. • The model overestimate is 10-20 ppbv on average but can be as high as 100 ppbv.
