More than 250 scientists, engineers, and flight personnel are participating in the Studies of Emissions, Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEAC4RS) campaign. The project is sponsored by the Earth Science Division in the Science Mission Directorate at NASA Headquarters in Washington. Brian Toon of the Department of Atmospheric and Oceanic Sciences at the University of Colorado, Boulder, is SEAC4RS lead scientist.

“In summertime across the United States, emissions from large seasonal fires, metropolitan areas, and vegetation are moved upward by thunderstorms and the North American Monsoon,” Toon said. “When these chemicals get into the stratosphere they can affect the whole Earth. They also may influence how thunderstorms behave. With SEAC4RS we hope to better understand how all these things interact.”

One benefit of this thorough examination of the region’s atmosphere will be more accurate satellite data.

“By using aircraft to collect data from inside the atmosphere, we can compare those measurements with what our satellites see and improve the quality of the data from space,” said Hal Maring of the Earth Science Division at NASA Headquarters.
