Description

ATL07QL is the quick look version of ATL07 and is based on the same algorithms that generate the ATL07 final data products. Once final ATL07 files are available, the corresponding ATL07QL files are removed. ATL07 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.
