The National Snow and Ice Data Center (NSIDC) is a United States information and referral center in support of polar and cryospheric research. NSIDC archives and distributes digital and analog snow and ice data and also maintains information about snow cover, avalanches, glaciers, ice sheets, freshwater ice, sea ice, ground ice, permafrost, atmospheric ice, paleoglaciology, and ice cores. NSIDC is part of the University of Colorado Boulder Cooperative Institute for Research in Environmental Sciences (CIRES), and is affiliated with the National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Information through a cooperative agreement. NSIDC serves as one of twelve Distributed Active Archive Centers funded by the National Aeronautics and Space Administration to archive and distribute data from NASA's past and current satellites and field measurement programs. NSIDC also supports the National Science Foundation through the Exchange For Local Observations and Knowledge of the Arctic (ELOKA) and other scientific research grants. NSIDC is also a member of the ICSU World Data System. Mark Serreze is the director of NSIDC. History The World Data Center (WDC) for Glaciology, Boulder, a data center responsible for archiving all available glaciological information, was established at the American Geographical Society under Dr. William O. Field, Director, in 1957. Between 1971 and 1976 it was operated by the U.S. Geological Survey, Glaciology Project Office, under the direction of Dr. Mark F. Meier. In 1976, responsibility for the WDC for Glaciology was transferred to NOAA, Environmental Data and Information Service (EDIS), and the center moved to the University of Colorado at Boulder under the direction of Professor Roger G. Barry. In 1982, NOAA created the National Snow and Ice Data Center (NSIDC) as a means to expand the WDC holdings and as a place to archive data from some NOAA programs. In the 1980s and 1990s, support to NSIDC widened with NASA funding for the Snow and Ice Distributed Active Archive Center (DAAC) and NSF funding to manage selected Arctic and Antarctic data and metadata.
