NASA's Tropical Composition, Cloud and Climate Coupling (TC4) field campaign will begin this summer in San Jose, Costa Rica, with an investigation into how chemical compounds in the air are transported vertically into the stratosphere and how that transport affects cloud formation and climate.

Scientists to search tropical skies

Scientists from NOAA’s Earth System Research Lab will be among 400 researchers in Costa Rica this summer to probe one of the most complex and least observed regions of Earth’s atmosphere during the rainy season. Based in San Jose, Costa Rica, the NASA-led field study will shed light on key processes related to climate change, the stratospheric ozone layer, and global chemistry. The study runs from July 2 through August 15.
