ATLAS/ICESat-2 L3A Sea Ice Height, Version 3

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.本数据集（ATL07）包含经大地水准面变化、潮汐变化及反气压效应校正后，相对于采用ITRF2014参考框架（ITRF2014 reference frame）的WGS84椭球体（WGS84 ellipsoid）的海冰与不同空间尺度冰间水道的沿轨高度数据。数据集同时提供高度统计量与表观反射率。该数据由搭载于冰、云与陆地高程卫星-2（ICESat-2）观测平台的先进地形激光测高系统（Advanced Topographic Laser Altimeter System，ATLAS）采集获取。
