ATLAS/ICESat-2 L3A Land and Vegetation Height, Version 6

This data set (ATL08) contains along-track heights above the WGS84 ellipsoid (ITRF2014 reference frame) for the ground and canopy surfaces. The canopy and ground surfaces are processed in fixed 100 m data segments, which typically contain more than 100 signal photons. The data were acquired by the Advanced Topographic Laser Altimeter System (ATLAS) instrument on board the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) observatory.本数据集（ATL08）收录了地表与冠层表面相对于WGS84椭球体（WGS84 ellipsoid）的沿轨高程数据，其坐标参考框架为ITRF2014（ITRF2014 reference frame）。冠层与地表数据均以固定100米的数据分段进行处理，每个分段通常包含100余个信号光子。该数据集由搭载于冰、云与陆地高程卫星-2（ICESat-2）观测平台上的先进地形激光测高系统（ATLAS）采集获取。
