TC4
Tropical Composition, Cloud, and Climate Coupling
The Tropical Composition, Cloud and Climate Coupling (TC4) was a NASA field campaign that investigated the structure, properties, and processes in the tropical Eastern Pacific. TC4 had 1 deployment based in Costa Rica and Panama during the boreal summer of 2007.
TC4 utilized airborne, ground-based, balloon, and satellite to study the microphysical and chemical properties of the tropical tropopause layer (TTL) to understand the role that TTL plays in Earth’s climate and atmospheric chemistry. TC4 was funded by the Upper Atmospheric Research Program, Radiation Science Program, and Tropospheric Chemistry Program.
The Real Time Mission Monitor provided simultaneous aircraft status for three aircraft during the TC4 experiment. During TC4, NASA's ER-2, WB-57, and DC-8 aircraft flew missions at various times. The science flights were scheduled between July 17 and August 8, 2007.
