Stewards of data, past and present
NOAA@NSIDC preserves data to support current and future research. Data products serve scientists engaged in research, decision makers planning activities affected by snow and ice, and members of the general public curious about the cryosphere.
The continued operation of NOAA@NSIDC and security of archived data over the long term depends on the continuation of federal funding for our work as part of NSIDC and CIRES. NOAA@NSIDC is the only archive for many of our data products.
