The Campaign

The Airborne Tropical Tropopause Experiment (ATTREX) was a NASA-led campaign designed to investigate stratospheric water vapor and its effect on the earth’s energy budget and climate. Measurements of atmospheric chemical composition and processes occuring in the Tropical Tropopause Layer (TTL) were collected using NASA’s Global Hawk UAV from 2011-2015. The first 2 deployments occurred from California in 2011 and 2013, while the remaining 2 took place from Guam during 2014 and 2015. Instruments onboard the Global Hawk aircraft included chemical sensors such as: the UAS Chromatograph for Tracers (UCATS) and the Harvard Picarro Cavity Ringdown Spectrometer, and a suite of meteorological instruments including the Meteorological Measurement System (MMS). ATTREX was primarily supported by the NASA EVS-1 program.
