TC4

The Tropical Composition, Cloud and Climate Coupling (TC4) mission was a NASA field campaign aimed at investigating the structure, properties and processes in the tropical Eastern Pacific. The goal of the project is to better understand the chemical, dynamic, and physical processes occurring in the tropical upper troposphere and tropopause transitional layer that influence global climate change, stratospheric ozone depletion, and global tropospheric chemistry.
