The Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) field mission will take place in two aircraft deployments over the Arctic during April and July 2008. It will involve the NASA DC8 as an in situ platform for detailed atmospheric composition.

The spring deployment will target anthropogenic pollution including arctic haze, stratosphere-troposphere exchange, and sunrise photochemistry including halogen radicals. The summer deployment will target boreal forest fires, stratosphere-troposphere exchange, and summertime photochemistry. ARCTAS is part of the international POLARCAT arctic field program for atmospheric composition.
