ATLAS/ICESat-2 L3A Land Ice Height, Version 2

This data set (ATL06) provides geolocated, land-ice surface heights (above the WGS 84 ellipsoid, ITRF2014 reference frame), plus ancillary parameters that can be used to interpret and assess the quality of the height estimates. 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（ATL06）提供了经地理定位的陆地冰表面高程数据（以WGS 84椭球体、ITRF2014参考框架为基准），同时附带可用于解读并评估高程估算结果质量的辅助参数。该数据由先进地形激光测高系统（Advanced Topographic Laser Altimeter System，缩写ATLAS）搭载于冰、云与陆地高程卫星-2（Ice, Cloud and land Elevation Satellite-2，缩写ICESat-2）观测台采集获取。
