Data Center Description
The USGS Global Change Research Program (USGS GCRP), an operational branch
of the U.S. Global Change Research Program (USGCRP), was established to
document data and information on past and present global environmental
change processes. The USGS GCRP Data Server was developed to provide
researchers with access to the data sets and documentation archived at the
USGS GCRP. This Data Server is located in Reston, VA, and provides on-line
access via the Internet.
Research conducted at the USGS GCRP include the following categories:
- Biogeochemical Exchanges between Terrestrial Systems and the Atmosphere
and Oceans
- Arid and Semiarid Regions Research
- Cold Regions Research
- Interaction of Climate and Hydrologic Systems
- Land Characterization and Land Data Management
- Paleoclimate Research
- Sensitivity of Water Resources
These research projects fall into two categories: the study of past
conditions (useful in the determination of natural climate variability)
and the study of modern environmental processes. Data from these projects
are also used to evaluate and improve upon general circulation models.
Several data sets are available on-line through the USGS GCRP Data Server via
anonymous FTP or the World Wide Web. Data sets are archived in the
following general categories:
- Modern Average Global Sea Surface Temperature
- Monthly Average Polar Sea Ice Concentration ( in preparation for publication
in the U.S. Geological Survey Digital Data Series as DDS-27)
- PRISM: Pliocene Research, Interpretation, and Synoptic Mapping
- Paleoclimate studies of the Arctic Ocean
- Methane and gas hydrates in Arctic sediments and permafrost
- Volcano Emissions
Data set descriptions, including metadata descriptions in the FGDC Metadata
Standard and the Directory Interchange Format, are provided with most data
sets. Core data, which consist of the essential observations and information
of each data set are provided and often derived data sets and additional
programs to manipulate or view the data are provided as well. A collection of
abstracts from current USGS global change research projects are also
archived and are accessible via the World Wide Web.
