ATLAS/ICESat-2 Expedited Data

Expedited elevation data from the Advanced Topographic Altimeter System (ATLAS) instrument are available through Land, Atmosphere Near real-time Capability for Earth observation (LANCE).

Update Oct. 2025: The ATL07QL and ATL10QL ATLAS/ICESat-2 expedited “Quick Look” data sets have been experiencing a data outage since September 30, 2025, due to the lapse in federal government funding. This is the result of a disruption to SSMIS (DMSP) data which is an input to these data sets. There is no current estimate for when normal operations will resume. We apologize for any inconvenience.


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.

NASA's Land, Atmosphere Near real-time Capability for Earth observation (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.
