With funding from the National Oceanic and Atmospheric Administration (NOAA), a small team at NSIDC manages, archives, and publishes data sets with an emphasis on in situ data and data from operational communities such as the U.S. Navy.  NOAA@NSIDC strives to digitize and publish old and sometimes forgotten but valuable analog data. We also help develop educational pages, contribute to larger center-wide projects, and support the Roger G. Barry Archives and Resource Center (ARC) at NSIDC.


NSIDC was established at the University of Colorado in 1982 by NOAA's National Environmental Satellite, Data, and Information Service (NESDIS) to serve as a national information and referral center for polar research. While NSIDC is not part of NOAA, we are affiliated with the NOAA National Centers for Environmental Information (NCEI) (formerly NGDC) through a cooperative agreement and archive and distribute our NOAA data in partnership with NCEI. NOAA@NSIDC activities are made possible by support from NOAA/NESDIS/NCEI and the NOAA Arctic Research Program.
