Data

NSIDC celebrates 25 years as a Distributed Active Archive Center (DAAC), archiving and distributing snow and ice data from NASA Earth Observing System (EOS) missions.

A new satellite instrument helps expand NSIDC's cryospheric satellite products, which provide snow and ice data extending from 1979 to the present.

Why is citing data important? Including data citations can be just as valuable as literature citations, not only to fellow researchers, but to those who compile data, organizations distributing data, and agencies that fund research.
