Elevation Change dataset in Greenland Ice Sheet

The dataset is named by the data and timespan. It contains three raster files and three excel files.

The raster files are the interpolated 5km×5km elevation change rate of GrIS using ordinary kriging in Stereographic North Pole projection coordinate system(EPSG 3413). The excel files contains four columns with the data information in each 5km gird cell, including center longitude, center latitude, the number of fitted points and the uncertainty of elevation change rate in each gird cell. It should be noted that the uncertainty of the elevation change rate in each grid cell is without filtering error data in order to meet different culling data needs.The uncertainty of elevation change is bigger as large as 0.5 m/yr over some areas of the edge of the GrIS In contrast, the inland area is smaller about 0.05 m/yr.
