OVERVIEW

---

In Spring and Summer 2008 NASA is conducting a campaign called Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS). The spring deployment targeted arctic haze, anthropogenic pollution in general, stratosphere-troposphere exchange, and sunrise photochemistry. The summer deployment is targeting boreal forest fires, stratosphere-troposphere exchange, and summertime photochemistry. ARCTAS is part of the international IPY/POLARCAT arctic field program for atmospheric composition.
