Earth Observing System
(EOS) Data Gateway (EDG) is the online search-and-order
system for Earth science data products from NASA and affiliated
centers. The EDG system allows users to search data holdings,
retrieve high-level descriptions of datasets, view browse images,
and place orders for data products.
Earth Observing System
Data Information System (EOSDIS) Distributed Active Archive
Centers (DAACs) are a network of nine discipline-specific
data centers that process, archive, document, and distribute
data from NASA's Earth observing satellites and field measurement
programs. All NASA Earth science data are described in the Global
Change Master Directory (GCMD), and most data can be ordered
via the EOS Data Gateway (EDG). In addition, each data center
has its own data-delivery methods and data-analysis tools.
EOS-Webster
is hosted by the University of New hampshire and provides
free, customized Earth Science data. Data holdings can
be searched spatially, temporally, by keyword, free text,
and/or collection name.
Earth Science Information
Partners (ESIP) Federation Find Tool
is powered by Mercury, a web-based system that searches
dataset descriptions and web pages for links to additional
information and documentation, providing data links when
available. ESIPs are government agencies, national laboratories,
universities, nonprofit organizations, and commercial businesses
collaborating to ensure better distribution of scientific
data and information.

Global Change Master
Directory (GCMD) holds more than 20,000
descriptions of Earth and environmental science datasets and services. Users can browse the description
inventory, as well as, search by controlled keywords or free
text, create or modify their own descriptions, and search
using customized portals for focused science communities.
Global Land Cover Facility
(GLCF) provides
Earth science data and products to further understanding
of global environmental systems. In particular, the GLCF
develops and distributes remotely sensed satellite data
and products that explain landcover from the local to global
scales. Primary data and products available at the GLCF
are free to anyone via FTP. Online datasets may be accessed
electronically through the Earth Science Data Interface
(ESDI).

Lamont-Doherty Earth
Observatory (LDEO) is
a leading research institution where more than 200 research
scientists seek fundamental knowledge about the origin,
evolution and future of the natural world. From global climate
change to earthquakes, volcanoes, nonrenewable resources,
environmental hazards and beyond, the Observatory's fundamental
challenge is to provide a rational basis for the difficult
choices faced by humankind in the stewardship of this fragile
planet. Data from research are available in the Databases
and Repositories section of the web site.

National Center for Atmospheric Research (NCAR)
is a federally funded research and development center. With
partners at universities and research centers, NCAR is dedicated
to exploring and understanding the atmosphere and its interactions
with the Sun, the oceans, the biosphere, and human society.
NCAR provides research tools for accessing/downloading data,
software to support data formatting, modeling, display and
analysis, and visualization, in addition to a wealth of
information on modeling Earth systems and processes to better
understand and predict their behavior.
National Climatic Data Center (NCDC)
is the world's largest active archive of weather data
and operates the World Data Center for Meteorology. NCDC
manages the U.S. resource of global climatological in-situ
and remotely sensed data and information to promote global
environmental stewardship; to describe, monitor and assess
the climate; and to support efforts to predict changes in
the Earth's environment. This effort requires the acquisition,
quality control, processing, summarization, dissemination,
and preservation of a vast array of climatological data
generated by the national and international meteorological
services.
National Geophysical Data Center (NGDC)
provides scientific stewardship, products and services for
geophysical data describing the solid earth, marine, and
solar-terrestrial environment, as well as earth observations
from space. NGDC's data holdings contain more than 300 digital
and analog databases.
National Ocenographic Data Center (NODC)
manages the acquisition, ingest processing, quality control
and long-term preservation of physical, chemical, and biological
oceanographic data. NODC hosts several web applications for
accessing, visualizing, and downloading data.
National
Snow and Ice Data Center (NSIDC)
provides data and information for snow and ice processes,
particularly interactions among snow, ice, atmosphere, and
ocean, in support of research in global change detection
and model validation. NSIDC also provides general data and
information services to the cryospheric and polar processes
research community.

Oak Ridge National Laboratory (ORNL)
provides data and information
about the dynamics between the biological, geological, and
chemical components of the Earth's environment. These dynamics
are influenced by interactions between organisms and their
physical surroundings, including soils, sediments, water,
and air.
