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. 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. While GTE began primarily as an aircraft-based program supplemented by ground-based measurements, satellite data and model analyses now play an important role. Space Shuttle observations of tropospheric carbon monoxide distribu-tions have helped to plan and direct the course of expeditions over tropical rain forests. Landsat land-surface images have facilitated the extrapolation of regional arctic-tundra measurements into global-scale conclusions. Weather data returned by environmental satellites and model analyses have guided flight planning for research aircraft. Modeling studies also
