This is the most recent version of these data.
Version Summary
Version Summary
-Removed canopy finding flag in ATL08 regions 7, 8, 9, 10, and 11
-Incorporated the CAB delineation of a ground surface to remove noise bands from the ATL03 data product prior to DRAGANN.
-Aligned the weak beam to the strong beam from ATL09 based on along-track distance for CAB profile cloud filtering
-Updated description for MSW flag
-Incorporated a single surface search to improve ground finding
-Updated parameters on the quality_ph flag to allow certain photons as input into ATL08
-Added a terrain and canopy quality score
-Added steps for identifying whether photons are from a single surface or multi-surface
-Added ground finding correction based on a priori DEM bias
-Added extension of nighttime canopy photons, above FINALGROUND surface
-Added steps to reject photons in the presence of fog or low-lying clouds

Overview
ATL08QL is the quick look version of ATL08 and is based on the same algorithms that generate the ATL08 final data products. Once final ATL08 files are available, the corresponding ATL08QL files are removed. ATL08QL contains along-track estimates of terrain height, canopy height, and canopy cover, as well as beam and reference parameters. Data were acquired by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the ICESat-2 observatory.
