The Advanced Topographic Altimeter System (ATLAS) aboard the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) collects global elevation data.

ICESat-2 Quick Look Data and Information

  • Download ICESat-2 quick look data directly from:
  • ICESat-2 landing page at NASA's National Snow and Ice Data Center DAAC (NSIDC DAAC)
  • Subscription to mailing lists by data set are available in the upper right corner of the data set landing pages

The Advanced Topographic Altimeter System (ATLAS) aboard the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) collects elevation data over all surfaces spanning the world’s frozen regions, forests, lakes, urban areas, and more. Subsets of ATLAS/ICESat-2 data such as sea ice height, land and vegetation height, atmospheric layer characteristics, sea ice freeboard, and inland water surface heights are now available at an expedited latency. These ATLAS/ICESat-2 quick look data with expedited latency will support a variety of users and applications, including sea ice forecasting and supporting decision-makers looking at vegetation height, surface water and flooding, and land surface deformation from landslides and volcanoes.

LANCE generally provides ICESat-2 quick look data within 3 days of satellite observation in comparison to an average latency of 45 days for the standard dataset.

Note: On Wednesdays, NSIDC DAAC systems typically undergo system maintenance and access to the ICESat-2 quick look data might not be available during these planned maintenance events. More precise maintenance times are available on the dataset landing pages on the day of the event.
