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 and contribute to larger center-wide projects 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.
