ATLAS/ICESat-2 L3A Sea Ice Freeboard, Version 4

This data set (ATL10) contains estimates of sea ice freeboard, calculated using three different approaches. Sea ice leads used to establish the reference sea surface and descriptive statistics used in the height estimates 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.

本数据集（ATL10）收录了采用三种不同计算方法得到的海冰干舷（sea ice freeboard）估算值。用于确立参考海面的海冰水道（sea ice leads），以及海冰高度估算过程中所用的描述性统计量，亦随数据集一并提供。本数据集的数据由搭载于冰、云与陆地高程卫星-2（ICESat-2）上的先进地形激光测高系统（ATLAS）采集获得。
