tion (NASA) conducted the Arctic Research of the Compo-sition of the Troposphere from Aircraft and Satellites (ARC-TAS) mission during 2008 as a part of the International Polar Year (IPY). The purpose of ARCTAS was to study the factors responsible for changes in the Arctic’s atmospheric compo-sition and climate. A major emphasis was to investigate Arc-tic haze, which is most pronounced during winter and early spring. This study focuses on the spring phase of ARCTAS (ARCTAS-A) that was based in Alaska during April 2008. Although anthropogenic emissions historically have been as-sociated with Arctic haze, biomass burning emissions dom-inated the ARCTAS-A period and have been the focus of many ARCTAS related studies. This study determines mean transport characteristics of anthropogenic emissions during ARCTAS-A. Trajectories
