New version release: ATLAS/ICESat-2 L1B Converted Telemetry and L2A Global Geolocated Photon Data

Versions 7 of ATLAS/ICESat-2 L1B Converted Telemetry Data (ATL02) and ATLAS/ICESat-2 L2A Global Geolocated Photon Data (ATL03) are now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). ATL03 contains height above the WGS 84 ellipsoid, latitude, longitude, and time for each photon downlinked by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board ICESat-2. ATL02 contains the associated time-ordered telemetry data used for system-level, quality control analysis by ATLAS. Improved corrections can be found in the metadata record.

Versions 6 of these data will be retired from the NSIDC DAAC on March 1st, 2026. Upon retirement, data will no longer be accessible, but all related documentation will remain available on the data set web page for future reference.
