Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS)

 Image representing the MISR project.

Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) is an aerosol experiment taking place in the Arctic in March, April, June, and July, 2008. The ARCTAS mission, one of the POLARCAT (POLar study using Aircraft, Remote sensing, surface measurements and modeling of Climate, chemistry, Aerosols and Transport) campaigns for the International Polar Year, is aimed at learning more about the state of the Arctic atmosphere and reporting on the changes that have occurred as a result of pollution. The experiment contains four deployments.
