我们比较了2014年夏季TanDEM-X原始DEM和2000年夏季SRTM c波段DEM在北巴塔哥尼亚冰原(NPI)上的冰高程,以获得过去14年冰高程变化率的详细图。用大地测量法计算了该地区和附近的南巴塔哥尼亚冰原(SPI)的物质平衡。对该方法进行了概述,并给出了误差估计。对数据的后向散射系数进行了分析,以排除雪和雪中信号穿透引起的高程偏差。
We compare ice elevation from TanDEM-X Raw DEMs of summer 2014 and from the SRTM C-band DEM of summer 2000 over the Northern Patagonian Icefield (NPI) in order to obtain a detailed map of ice elevation change rates over the last 14 years. The geodetic method is used to compute the mass balance for this region and for the nearby Southern Patagonian Icefield (SPI). The method is outlined along with the error budget estimation. The backscattering coefficient of the data is analyzed in order to exclude elevation biases due to signal penetration in snow and firn.
