ATLAS/ICESat-2 L3A Sea Ice Height Quick Look, Version 6

ATL07QL is the quick look version of ATL07. Once final ATL07 files are available, the corresponding ATL07QL files will be removed. ATL07 contains along-track heights for sea ice and open water leads (at varying length scales) relative to the WGS84 ellipsoid (ITRF2014 reference frame) after adjustment for geoidal and tidal variations and inverted barometer effects. Height statistics and apparent reflectance are also provided. 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.

ATL07QL为ATL07的快速预览版本。当正式版ATL07文件发布后，对应的ATL07QL文件将被删除。ATL07数据集包含海冰与开阔水域冰间水道（尺度范围各异）的沿轨高程数据，该数据以WGS84椭球体（WGS84 ellipsoid）为高程基准，处于ITRF2014参考框架（ITRF2014 reference frame）下，并已完成大地水准面起伏、潮汐变化与倒气压效应的校正处理。数据集同时提供高程统计量与表观反射率产品。本数据集由搭载于冰、云与陆地高程卫星-2（Ice, Cloud and land Elevation Satellite-2, ICESat-2）观测平台的先进地形激光测高系统（Advanced Topographic Laser Altimeter System, ATLAS）获取。
