本数据集包括了Beascochea海湾沿岸 101 条入海冰川的表面运动速率，时间从2015年到2025年，分辨率为90ｍ*90ｍ，采用Sentinel-1卫星提供中心频率为5.405 GHz的C波段合成孔径雷达(SAR)数据(Rostan et al., 2007)。本研究利用SAR 强度偏移追踪法反演冰川表面运动速度，基于 GAMMA 软件实现。首先结合卫星轨道参数与 DEM 数据完成影像精确配准，再利用单视复数（SLC）影像计算方位向与斜距向偏移量，最后通过地理编码转换至 WGS84 坐标系。为提升匹配精度，采用过采样处理，设置匹配窗口为 256×64，相关系数阈值为 0.05。以非冰川覆盖的稳定区域为参考，计算均方根误差（RMSE），综合评估影像配准、偏移追踪及电离层影响带来的误差。详细生产过程见 Kang et al., 2026, Int.
