The Union of Concerned Scientists (UCS) Satellite Database is a listing of operational satellites currently in orbit around the Earth. It is available as a downloadable Excel file, which is updated roughly quarterly. Our intent in producing the database is to create a research tool for specialists and non-specialists alike by collecting open-source information on operational satellites and presenting it in a format that can be easily manipulated for research and analysis. The database includes basic information about more than 800 satellites and their orbits, but does not contain the detailed information necessary to locate individual satellites. The UCS Satellite Database is the only free, comprehensive compilation of active satellites in an easy to manipulate, commonly-used database format. Users can find information about a particular satellite; identify sets of satellites having a common characteristic, such as altitude or mission; and sort or aggregate data about the whole population of satellites.

Since 1985, NOAA's Pacific Marine Environmental Laboratory (PMEL) and Atlantic Oceanic and Meteorological Laboratory (AOML) have been measuring atmospheric and surface sea water pCO2 on board the NOAA ships Oceanographer, Discoverer, Malcolm Baldrige, Ka'imimoana and Ron Brown. In addition, pCO2 measurements are made on vessels of opportunity ships (VOS) including the Columbus Waikato and Explorer. The methods are described in Wanninkhof and Thoning (1993) and Feely et al (1998). Select an ocean region to access underway pCO2 data

Providing data, tools, and community leadership for enhanced Earth-system education and research. Unidata provides a broad array of data to our community for use in many geoscientific applications. Unidata develops and supports tools that facilitate the analysis and visualization of geoscience data. Unidata is a diverse community of institutions vested in the common goal of sharing data, and tools to access and visualize that data.

The North American Node of UNEP GRID, located at the USGS EROS Data Center, is in the forefront of applying information technology tools such as remote sensing, Geographic Information Systems (GIS) and web mapping to address the relationships between the environment and human populations. Utilizing the expert knowledge of staff and visiting scientists, the information created with these tools provide policy-makers a scientific basis for making decisions. GRID Sioux Falls operates in cooperation with UNEP, NASA, USGS, USFS and US EPA and is guided by an advisory committee attended by representatives from Canada, Mexico and the United States.

The mission of the Agency for Toxic Substances and Disease Registry (ATSDR), as an agency of the U.S. Department of Health and Human Services, is to serve the public by using the best science, taking responsive public health actions, and providing trusted health information to prevent harmful exposures and disease related to toxic substances. ATSDR is directed by congressional mandate to perform specific functions concerning the effect on public health of hazardous substances in the environment. These functions include public health assessments of waste sites, health consultations concerning specific hazardous substances, health surveillance and registries, response to emergency releases of hazardous substances, applied research in support of public health assessments, information development and dissemination, and education and training concerning hazardous substances.

The Bureau of Transportation Statistics (BTS) was born as a statistical agency in 1992. The Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991 established BTS for data collection, analysis, and reporting and to ensure the most cost-effective use of transportation-monitoring resources. BTS brings a greater degree of coordination, comparability, and quality standards to transportation data, and to fill important gaps.

The Energy Information Administration (EIA), created by Congress in 1977, is a statistical agency of the U.S. Department of Energy. We provide policy-independent data, forecasts, and analyses to promote sound policy making, efficient markets, and public understanding regarding energy and its interaction with the economy and the environment.

The National Space Science Data Center (NSSDC) provides multidiscipline data and information services, including a large digital data archive from past NASA space science missions along with directories, catalogs, and access to widely distributed science data resources. The NSSDC is responsible for the long term archiving and preservation of all space science data. The NSSDC works closely in federation with the other Office of Space Science (OSS) sponsored discipline data centers. This federation is responsible for providing a coherent and coordinated OSS-wide data environment to improve quality, accessibility, and usability of NASAs space data holdings for scientists, educators, and the general public.

The National Data Buoy Center (NDBC) is an agency within the National Weather Service (NWS) of the National Oceanic and Atmospheric Administration (NOAA). The National Data Buoy Center (NDBC) manages the development, operations, and maintenance of the national data buoy network. It serves as the NOAA focal point for data buoy and associated meteorological and environmental monitoring technology. It provides high quality meteorological/environmental data in real time from automated observing systems that include buoys and a Coastal-Marine Automated Network (C-MAN) in the open ocean and coastal zone surrounding the United States. It provides engineering support, including applications development, and manages data buoy deployment and operations, and installation and operation of automated observing systems installed on fixed platforms. It manages the Volunteer Observing Ship (VOS) program to acquire additional meteorological and oceanographic observations supporting NWS mission requirements. It operates the NWS test center for all surface sensor systems. It maintains the capability to support operational and research programs of NOAA and other national and international organizations. The US Coast Guard is the primary source of transportation for buoy deployments, retrievals, and maintenance.

The National Nuclear Data Center (NNDC) collects, evaluates, and disseminates nuclear physics data for basic nuclear research and for applied nuclear technologies. The NNDC is a worldwide resource for nuclear data. The information available to the users of NNDC services is the product of the combined efforts of the NNDC and cooperating data centers and other interested groups, both in the United States and worldwide.

NOAA's National Geophysical Data Center (NGDC) provides scientific stewardship, products, and services for geophysical data describing the sea floor, solid earth, and solar-terrestrial environment, including Earth observations from space.

The U.S. Waterway Data is a collection of data related to the navigable waters in the United States, including inland waterways, off-shore waters, the Great Lakes, and the Saint Lawrence Seaway. Data on commerce, facilities, locks, dredging, imports and exports, and accidents are included along with the geographic waterway network. The data were compiled from several agencies, including the U.S. Army Corps of Engineers Navigation Data Center, the U.S. Bureau of the Census, the U.S. Coast Guard, Oak Ridge National Laboratory, and Vanderbilt University. One of the objectives of this coordinated effort is to make waterway data more widely available and easily accessible. The data included here are in standard file formats that can be easily imported into other software tools such as spreadsheets, databases, and Geographic Information Systems (GIS).

The PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories. Hosted by the US Department of Agriculture Natural Resources Conservation Service (NRCS).

The Earth Resources Observation Systems (EROS) Data Center (EDC) is a data management, systems development, and research field center for the U.S. Geological Survey's (USGS) National Mapping Division. Organizationally, the USGS is a bureau of the U.S. Department of the Interior. The EDC opened in the early 1970's with a handful of employees and the largest mainframe computer in the State of South Dakota. Today the EDC has approximately 600 government and contractor employees, including employees at its Alaska Field Office in Anchorage, Alaska, and employees at the NASA Ames Research Center in Moffett Field, California. And now the EDC houses one of the largest computer complexes in the Department of the Interior. Products: Aerial maps, Elevation maps, Satellite maps, Land cover maps.
