Airborne Tropical TRopopause EXperiment (ATTREX)
Data and Information

The Airborne Tropical TRopopause EXperiment (ATTREX) was conducted through three field deployments in Lancaster, CA (2011 and 2013) and Guam (2014). The ATTREX measurements include trace gas mixing ratio, radiation flux, cloud properties, and meteorological parameters. The primary ATTREX sampling region was Tropical Tropopause Layer at altitude range of 13 – 19 km. The ATTREX airborne+ instrument payload is designed to address the following three science objectives: 1) the role of stratospheric water vapor in Earth's energy budget and climate; 2) dehydration of tropospheric air entering the stratosphere; and 3) the physical processes and chemical composition of the Tropical Tropopause Layer (TTL) which is the region of the atmosphere that controls the composition of the stratosphere.
