The Global Tropospheric Experiment

The Global Tropospheric Experiment (GTE) is a major component of the NASA Tropospheric Chemistry Program. GTE consists of a series of airborne field experiments designed to (1) evaluate the capability of instrument techniques to measure, under field conditions, the minute concentrations of key chemical species in the atmosphere and (2) systematically address tropospheric chemistry issues relevant to global change, through airborne sampling expeditions, coupled with modeling and laboratory studies. See GTE map for location and brief description of each mission. See Tables below for detailed list of parameters in each mission archive.
