NSIDC is the leader in the field of cryospheric data management and distribution. They also conduct research and education. These data come from the field or are relayed from Earth-orbiting satellites. “The NSIDC supports research into our world’s frozen realms: the snow, ice, glacier, frozen ground, and climate interactions that make up the Earth’s cryosphere.”
NSIDC is part of the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado at Boulder.
CIRES, in turn, is one of the 21 joint research institutes of NOAA, the National Oceanic and Atmospheric Administration. One of these is at GFDL (Geophysical Fluid Dynamics Laboratory) on Princeton University’s Forrestal Campus, the Cooperative Institute for Climate Science
