The daunting effort this group is crafting will be NASA's most complex and ambitious airborne science campaign of the year: the Southeast Asia Composition, Cloud, Climate Coupling Regional Study, or SEAC4RS. With support from the National Science Foundation and the Naval Research Laboratory, the campaign will draw together coordinated observations from NASA satellites, several research aircraft, and an array of sites on the ground and at sea. The campaign is sponsored by the Earth Science Division in the Science Mission Directorate at NASA Headquarters in Washington.
