Data From the Federation's Archive Centers
The Federation maintains over 3,500 Earth Science datasets. Every one is available to scientists, educators, policy makers, students, and the general public. The vast majority of the data is free. Federation partners are working together to develop new datasets that apply to specific interests bringing Earth science data to an ever expanding arena of users.

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. Since its opening, the EDC has stored, processed, and distributed a variety of data, including cartographic data, satellite data, and aircraft data. The EDC houses a variety of USGS digital cartographic data products collectively referred to as US GeoData. The EDC's archives also hold the world's largest collection of civilian remotely sensed data covering the Earth's land masses, housing millions of satellite images and aerial photographs. As part of its role as a data archive, the EDC operates the National Satellite Land Remote Sensing Data Archive, a legislatively mandated program designed to maintain a high quality data base of space-acquired images of the Earth for use in studying global change and other related issues. |

 The Multi-angle Imaging SpectroRadiometer (MISR) was successfully launched into sun-synchronous polar orbit aboard Terra, NASA's first Earth Observing System (EOS) spacecraft, on December 18, 1999. MISR measurements are designed to improve our understanding of the Earth's environment and climate. MISR data products are available from LaRC. Selected MISR images can be seen at the Image Gallery. |

The National Geophysical Data Center, one of three NOAA Data Centers, is the steward of the Nation's geophysical data maintaining the world's largest collection of seafloor and space environment data, geophysical observations such as geomagnetism, and is the sole archive of the complete data stream from the Defense Meteorological Satellite Program (DMSP). NGDC builds and maintains long-term archives of scientific data, with a special emphasis on scientific stewardship of data acquired by NOAA observing systems, allowing future generations to look to these data sets and address future challenges.
NGDC, located in Boulder, Colorado, works closely with other government agencies, industry, academia, and foreign contributors to build the data resources required to monitor, understand, and predict the environment. NGDC data and products support industry, education and public requirements for environmental information. NGDC currently services 2.6 million requests per year which will grow to 4.2 million by the year 2011. NGDC also operates three collocated ICSU World Data Centers: Marine Geology and Geophysics, Solar terrestrial Physics and Solid Earth Geophysics. In cooperation with the University of Colorado, NGDC also supports the WDC for Glaciology.

The National Oceanographic Data Center (NODC) serves the Nation with data and information for understanding the ocean and its role in our lives. NODC archives and provides public access to oceanographic observational data and products, provides scientific oceanographic data services, and conducts assessments of the ocean environment. NODC manages the world's largest collection of publicly available oceanographic data. Holdings include in situ and remotely sensed physical, chemical, and biological oceanographic data from coastal and deep ocean areas. |

There are projects and data products available online, on CD-ROM, DVD, and in print. Also, check out the major program data page.
The World Ocean Database retrieval system allows the user to select criteria and search for data in the World Ocean Database 2001 (WOD01). The stations matching the user's search criteria can then be extracted and made available (via FTP) in WOD01 native data format.

The National Snow and Ice Data Center (NSIDC) archives and distributes digital and analog snow and ice data. The center maintains data and information for a variety of cryospheric indices including snow cover, avalanches, glaciers, ice sheets, freshwater ice, sea ice, ground ice, permafrost, atmospheric ice, paleoglaciology, and ice cores. NSIDC publishes reports and a quarterly newsletter, and creates and distributes data products electronically via ftp, on CD-ROM and other media. The center hosts a large library collection of monographs, technical reports, and journals. As the snow and ice DAAC under the NASA EOS Program, NSIDC archives and distributes products from the Terra, Aqua, and ICESat missions as well as Polar Pathfinder data sets.
In addition to distributiing NASA snow and ice products, NSIDC scientists are developing innovative tools to monitor snow cover for climate studies, hydrologic research, and catastrophic events such as the severe snowfall in the Hindu Kush.
