NASA global tropospheric experiment

Abstract

A major research effort, the Global Tropospheric Experiment (GTE), has been initiated by the National Aeronautics and Space Administration (NASA) to study the chemistry of the global troposphere and its interaction with the stratosphere, land, and oceans. The project currently involves approximately 20 principal investigators from 16 different institutions and is expected to expand over the next decade. The first phase of the project is aimed at developing and validating measurement techniques for trace species in tropospheric chemical cycles. It is designed to lead toward development and implementation of a cooperative research program involving NASA, scientists sponsored by the National Science Foundation, the National Oceanic and Atmospheric Administration, other government agencies, and research institutions abroad. The goal of the GTE is to understand the chemical cyles that control the composition of the global troposphere and its changes.
