Data from Cryosat-2 satellite showing elevation change over Pine Island Glacier and Thwaites Glacier

Rates of elevation change for 2010-2017 derived from interferometric measurements from Cryosat-2. Elevation change was derived from interferometric measurements from Cryosat-2. ESA L1b waveforms retrieved by the satellite in its SARIn (synthetic aperture radar interferometry) mode were processed following the swath processing approach of Gray et al(2013). The resulting dense set of time-dependent elevation measurements was used to derive elevation changes in a Eulerian framework at a 500 m resolution following the method presented in Wouters et al. (2015).

本数据集提供2010-2017年的高程变化速率，该数据由CryoSat-2卫星的干涉测量结果反演得到。处理过程中，该卫星在合成孔径雷达干涉测量（SARIn）模式下获取的欧洲空间局（ESA）L1b级波形数据，遵循Gray等人2013年提出的条带处理方法完成预处理。最终得到的高密度时序高程测量数据集，按照Wouters等人2015年发表的方法，在欧拉框架下以500米的空间分辨率反演得到了对应的高程变化。
