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.
