Description
Summary:This dataset provided the long-term elevation change rates data of the GrIS in three different periods using the ICESat data (February 2003 to October 2009), the Cryosat-2 data (August 2010 to October 2018) and the ICESat-2 data (October 2018 to December 2020) respectively. The dataset is named by the data. It contains three raster files and three shpfiles. The raster files are the interpolated 5 km×5 km elevation change rate of GrIS using ordinary kriging in Stereographic North Pole projection coordinate system (EPSG 3413). The Shpfiles are the uncertainty information. Each file contains three columns including Uncertain, calculated, interpolat. ‘Uncertain’ is the uncertainty of elevation change rate in each gird cell. ‘Calculated’ and ‘interpolat’ mean this gird cell is the calculated or interpolated one. ... : 本数据集分别利用ICESat数据(2003年2月至2009年10月)、Cryosat-2数据(2010年8月至2018年10月)和ICESat-2数据(2018年10月至2020年12月)提供了格陵兰冰盖三个不同时期的高程变化率。数据集由卫星测高数据名称命名。它包含三个栅格文件和三个shpfile文件。栅格文件空间分辨率为5km×5km，投影坐标为极地立体投影(EPSG 3413)。shpfile文件包含三个属性：Uncertain, calculated, interpolat。Uncertain表示每一个栅格值对应的不确定性，calculated和interpolat表示此栅格为拟合计算还是插值计算所得。 ...
