The NSIDC DAAC archives and distributes brightness temperature data, polar atmosphere data, satellite imagery, sea ice data, snow cover data, and ice sheet data. All NSIDC data are described and available through our Advanced Data Search tool.

Visible Infrared: NSIDC distributes visible and infrared data from the TIROS Operational Vertical Sounder (TOVS) suite of instruments, the MODIS instruments, and the AVHRR instrument.

LIDAR: NSIDC distributes laser data from the GLAS instrument.

Passive Microwave: NSIDC distributes passive microwave data from the AMSR-E instrument, the AMSR instrument, the SSMR instrument, and the SSM/I instrument.

Active Microwave: NSIDC distributes active microwave data from the RADARSAT instrument, scatterometer instruments, and radar altimeters.

Digital Elevation Models: NSIDC uses polar ice sheet elevation data sets to create surface elevation maps of the Greenland and Antarctic ice sheets. The maps contribute to the study of glaciers, ice sheets, ice streams, and ice shelves. Many of the maps produced from elevation data sets are Digital Elevation Models (DEMs), which facilitate ice sheet mass balance investigations and tracking of long-term changes in the polar ice sheets.
