1. Project/Campaign Overview:

In 1984, the National Academy of Sciences recommended initiation of a Global Tropospheric Chemistry Program (GTCP), in recognition of the central role of tropospheric chemistry in global change. Envisioned as the U.S. national component of an ultimately international research effort, GTCP calls for the systematic study, supported by numerical modeling, of (1) biological sources of atmospheric chemicals; (2) global distributions and long-range transport of chemical species; and (3) reactions in the troposphere that lead to the conversion, redistribution, and removal of atmospheric chemicals.

These research challenges demand a broadly-based program to address them. The resources required are distributed among several federal agencies, scores of universities, and a variety of scientific disciplines - including atmospheric science, biology, land processes, and oceanography. It was already clear in 1984, however, that the National Aeronautics and Space Administration (NASA) would play a leading role in such a program. Some GTCP objectives require large-scale field studies and the most advanced instrumentation. NASA brings together the unique research facilities, strength in atmospheric science, technical expertise, and management skills needed to achieve these objectives.

NASA's contribution to GTCP is the Global Tropospheric Experiment (GTE), which utilizes large, extensively instrumented aircraft - ideal platforms for many atmospheric chemistry experiments--as primary research tools. However, GTE also draws heavily upon satellite observations of meteorology, land use, and atmospheric chemical species to aid in experiment design and in the scientific analyses of results obtained from aircraft and ground-based measurements. The GTE is managed through the Tropospheric Chemistry Program in NASA's Earth Science and Application Division of the Office of Space Science and Applications.

Name of Project/Campaign:

Global Tropospheric Experiment, GTE

Project/Campaign Introduction:

The goal of the National Aeronautics and Space Administration's (NASA) Tropospheric Chemistry Program is to develop an understanding of the chemical cycles that control the composition of the troposphere and to assess the susceptibility of the global atmosphere to chemical change. A major component of the NASA program is the Global Tropospheric Experiment (GTE), which 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. The GTE airborne expeditions have focused on studies of the remote global atmosphere in order to provide well documented base line measurements of the unperturbed environment and to fully understand the chemical cycles underlying the natural environment.

The GTE, managed through the Tropospheric Chemistry Program in the Mission to Planet Earth Office, at NASA Headquarters, was initiated in the early 1980s. Implementation of the GTE Project is via a Project Office at the NASA Langley Research Center, Atmospheric Science Division.

Project/Campaign Mission Objectives:

Objectives of the NASA Tropospheric Chemistry Program, which encompasses GTE, are to:

In general, the objectives of the GTE series of field expeditions are (1) to evaluate the performance of new instrument techniques for measurement of key trace tropospheric species, and (2) to address specific tropospheric chemistry issues relevant to global change.

Discipline(s):

Atmospheric chemistry, instrument development for airborne and laboratory studies, theoretical models, and meteorology are the major scientific disciplines employed in meeting the objectives of GTE.

Geographic Region(s):

Table 1 lists general geographic regions where intensive airborne measurements for GTE expeditions have been conducted. Data were also obtained during aircraft transits to and from these regions and at ground sites. Detailed geographic information is provided in the Data set Documents for each expedition.

Detailed Project/Campaign Description:

The GTE expeditions have been conducted in a diverse range of environments and with different scientific goals. The Chemical Instrument Test and Evaluation (CITE) series were designed to expose selected instrumentation to a wide range of measurement conditions. The Atmospheric Boundary Layer Experiments (ABLE) have been conducted over ecosystems known to have significant influence on the troposphere. The long range transport of natural and anthropogenic emissions on the global troposphere have been investigated in the Pacific Exploratory Missions (PEM) and the Transport and Atmospheric Chemistry Experiment in the Atlantic (TRACE-A).

The dates and general geographic regions for each mission are listed in Table 1.
