DC-8 Advanced Vertical Atmospheric Profiling System Dropsondes (AVAPS) TC4
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/tc4/dc8avaps/data101
The Advanced Vertical Atmospheric Profiling System (AVAPS) dataset consists of vertical atmospheric profile measurements collected by the Advanced Vertical Atmospheric Profiling System (AVAPS) dropsondes released from the NASA DC-8 aircraft.
Description
The observations took place during the the Tropical Composition, Cloud, and Climate Coupling (TC4) field campaign. TC4 occurred 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 June 28 through August 8, 2007 in ICARTT-ASCII and JPG formats.
