National Snow and Ice Data Center (NSIDC)

NSIDC provides cryospheric data and information gathered from such sources as remote sensing instruments, ground measurements, and models. Established by NOAA as a national information and referral center in support of polar and cryospheric research, NSIDC archives and distributes digital and analog snow and ice data. We also maintain information about snow cover, avalanches, glaciers, ice sheets, freshwater ice, sea ice, ground ice, permafrost, atmospheric ice, paleoglaciology, and ice cores.
