WB-57 Meteorological and Navigation Observations (METNAV) TC4

These measurements were taken from the NASA WB-57 aircraft during the Tropical Composition, Cloud, and Climate Coupling (TC4) field campaign. TC4 took place during the boreal summer of 2007, with the primary goal was to better understand the role that the tropical tropopause layer (TTL) plays in the Earth’s climate and atmospheric chemistry by using in situ and remotely sensed products from the ground, balloons, and aircraft with data collected from NASA satellites.

TC4 allowed researchers to gain insight into convective transport between the ground and the TLL, and into transport mechanisms across the TTL. Data are available from August 1 through August 13, 2007 in ICARTT-ASCII and PDF formats.
