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

The data set (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.

数据集（ATL07）包含覆盖不同长度尺度的海冰与冰间水道沿轨高度数据，该数据以WGS84椭球体（WGS84 ellipsoid）为基准，采用ITRF2014参考框架（ITRF2014 reference frame），且已完成大地水准面变化、潮汐变化及倒气压效应的校正。数据同时提供高度统计量与表观反射率。本数据集由搭载于冰、云与陆地高程卫星-2（ICESat-2）的先进地形激光高度计系统（ATLAS）获取。
