This dataset exhibits the spatiotemporal variation of Greenland Ice Sheet (GrIS) supraglacial drainage system from 2017 to 2021, with a spatial resolution of 10 m and a temporal resolution of 1 year. The dataset type is integer raster, where the raster value 1 represents the supraglacial drainage system, and 0 represents the rest. The format of this dataset is GeoTIFF, and the total data volume is 3272.9 MB. This dataset is derived from Sentinel-2 satellite images using multi-scale remote sensing information extraction method. The overall accuracy of this dataset is higher than 85%, compared with manual interpretation. This dataset reflects the potential of mid and high resolution satellite remote sensing images in GrIS hydrological researches, and improves the understandings of key hydrological processes such as surface meltwater transport and storage.
