IceBridge ATM L4 Surface Elevation Rate of Change, Version 1

This data set contains surface elevation rate of change measurements derived from IceBridge and Pre-IceBridge Airborne Topographic Mapper (ATM) widescan elevation measurements data for Arctic and Antarctic missions flown under NASA's Operation IceBridge (OIB) and Arctic Ice Mapping (AIM) projects.本数据集包含表面高程变化率测量值，这些测量值源自冰桥行动（IceBridge）及前冰桥时期的机载地形测绘仪（ATM）宽扫描高程测量数据，适用于美国国家航空航天局（NASA）冰桥行动（OIB）和北极冰盖测绘（AIM）项目下执行的北极与南极任务。
