Data Set ID:
ATL07QL
Data Set Summary:
ATL07QL is the Quick Look (QL) version of ATL07 with an expedited latency of 3‒5 days. QL data are based on the same algorithms that generate the standard products but do not undergo the same rigorous quality checks; thus, they should be used with caution. Once final files are available, the corresponding QL files are removed. ATL07QL contains along-track sea surface height and sea ice height for segments of variable lengths for all beams as well as fixed 10-meter segments for strong beams. Heights are also computed using the DDA-Bifurcation algorithm for strong beams. The data were acquired by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the ICESat-2 observatory.
