- Global Change Data and Information System (GCDIS)
GCDIS is a collection of distributed information systems operated by government agencies involved in global change research. GCDIS provides global change data to scientists and researchers, policy makers, educators, industry, and the public at large and includes multidisciplinary data from atmospheric science, ecology, oceanography, as well as economics and sociology. GCDIS is a cooperative activity of agencies participating in the U.S. Global Change Research Program (USGCRP).
- Global Change Master Directory (GCMD)

- Goddard Institute for Space Studies (GISS)
GISS, a NASA research institute, is located near Columbia University in New York City, New York. GISS is a subdivision of the Goddard Space Flight Center's (GSFC) Earth Sciences Directorate in Maryland. A key objective of the GISS research is prediction of atmospheric and climate changes in the 1990s and early 21st century. The research combines analysis of comprehensive global datasets derived mainly from spacecraft observations with global models of atmospheric, land surface, and oceanic processes. The research approach includes study of past changes on Earth such as paleoclimate changes and study of other planets as an aid to prediction of future evolution of the Earth on a planetary scale. The perspective provided by space observations is crucial for monitoring global change and for providing data needed to develop an understanding of the Earth system. As the principal NASA center for Earth observations, the GSFC plays a leading role in global change research. Global change studies at GISS are closely coordinated with research at GSFC's Laboratories for Atmospheres, Hydrospheric Processes and Terrestrial Physics.

- World Ocean Circulation Experiment (WOCE)
WOCE is an unprecedented effort during 1990-1997 by scientists from more than 30 nations to study the large-scale circulation of the ocean. WOCE will employ several satellites, dozens of ships, and thousands of instruments to obtain a basic description of the physical properties and circulation of the global ocean during a limited period. In addition, WOCE is supporting regional experiments, the knowledge from which should improve circulation models, and it is exploring design criteria for long-term measurements with which to assess the representativeness of the global "snapshot." This knowledge will help unravel the role of the ocean circulation in decadal-scale climate change; the data obtained will help develop models for the prediction of such change.
