The AmeriFlux network, established in 1996, includes more than 120 independently funded sites operating across North, Central, and South America. AmeriFlux sites include tundra, grassland, agricultural crops, tropical forests and temperate coniferous and deciduous forests. The diversity of AmeriFlux sites greatly expands upon the contributions of other regional networks. AmeriFlux sites have provided a sustained set of detailed observations of ecosystem level exchanges of CO2, water, energy and momentum on an hourly basis, spanning diurnal, synoptic, seasonal, and interannual time scales. These data have provided a wealth of information on how diverse ecosystems respond to changes in their physical environment, and how they affect their environments in turn. Contributions to carbon cycle science include understanding variation in net carbon uptake with inter-annual variation in climate, and the influence of disturbance on carbon storage and fluxes.

The Atmospheric Radiation Measurement (ARM) Program is the largest global change research program supported by the U.S. Department of Energy (DOE). It was created to help resolve scientific uncertainties related to global climate change, with a specific focus on the crucial role of clouds and their influence on radiative feedback processes in the atmosphere. The primary goal of the ARM Program is to improve the treatment of cloud and radiation physics in global climate models in order to improve the climate simulation capabilities of these models. ARM's scientists research a broad range of issues that span remote sensing, physical process investigation and modeling on all scales. ARM's site operators focus on obtaining continuous field measurements and providing data products to promote the advancement of climate models.

The Carbon Dioxide Information Analysis Center (Thomas A. Boden, Director), which includes the World Data Center for Atmospheric Trace Gases, is the primary global-change data and information analysis center of the U.S. Department of Energy (DOE).

CDIAC responds to data and information requests from users from all over the world who are concerned with the greenhouse effect and global climate change. CDIAC's data holdings include records of the concentrations of carbon dioxide and other radiatively active gases in the atmosphere; the role of the terrestrial biosphere and the oceans in the biogeochemical cycles of greenhouse gases; emissions of carbon dioxide to the atmosphere; long-term climate trends; the effects of elevated carbon dioxide on vegetation; and the vulnerability of coastal areas to rising sea level.

On the other hand, CDIAC does not specialize in information on the medical aspects of carbon dioxide exposure, or industrial and household uses of carbon dioxide (for example, commercial sources of canisters of compressed CO2 gas, or fire extinguisher supplies).

CDIAC is supported by DOE's Climate Change Research Division of the Office of Biological and Environmental Research. CDIAC represents DOE in the multi-agency Global Change Data and Information System. Wanda Ferrell is DOE's Program Manager with responsibility for CDIAC.

CICOR completed its first cooperative agreement with NOAA OAR, which lasted 3 years, in the summer of 2001. A new 5-year cooperative agreement was signed in July 2001. The success of CICOR in facilitating the funding of NOAA research at WHOI was reflected by the 31 proposals that were funded through CICOR by the end of the first cooperative agreement. A Memorandum of Agreement (MOA) established the formal partnership between Woods Hole Oceanographic Institution and the National Oceanic and Atmospheric Administration. CICOR provides a framework at WHOI for coordinating NOAA-funded research, for building ties between WHOI investigators and colleagues at NOAA laboratories, and for developing cooperative NOAA-funded research at academic institutions in the northeastern United States. A number of these activities are outlined below. Scientists at the Institution have ties to colleagues and research activities at other NOAA laboratories, especially Great Lakes Environmental Laboratory (GLERL), Atlantic Oceanographic and Meteorological Laboratory (AOML) and Pacific Marine Environmental Laboratory (PMEL); and to sister Joint Institutes, particularly Cooperative Institute for Limnology and Ecosystems Research (CILER), Joint Institute for Marine Observations (JIMO), Joint Institute for Marine and Atmospheric Research (JIMAR) and Cooperative Institute for Marine and Atmospheric Studies (CIMAS).

The Defense Meteorological Satellite Program (DMSP) is a Department of Defense (DoD) program run by the Air Force Space and Missle Systems Center (SMC). The DMSP designs, builds, launches, and maintains satellites monitoring the meteorological, oceanographic, and solar-terrestrial physics environments.

GOSIC is established at the College of Marine Studies of the University of Delaware, USA, to provide a single entry point for users for data and information produced by the global observing systems GCOS, GOOS, and GTOS. Some needs of these global observing systems are provided by partner observing programs such as the Global Atmosphere Watch (GAW), the World Weather Watch (WWW), and the Joint Commission on Oceanography and Marine Meteorology (JCOMM). GOSIC provides access to data and information of these partner programs, but not always to the same level of detail.
