ATLAS/ICESat-2 L2A Global Geolocated Photon Data Low Latency, Version 7 (ATL03LL) is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). ATL03LL 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. This data set is an expedited version of ATL03, where the data acquisition and algorithm are the same, but the geolocation processing has been adjusted to provide a product available within 4 to 7 days.
