It compiles the spatial distribution of glaciers within this region and the glacier surface elevation change data from 2000 to 2020.\n\nThe dataset primarily includes glacier boundaries extracted from the Randolph Glacier Inventory (RGI) 6.0 and 7.0, as well as glacier surface elevation change rates for four periods: 2000–2005, 2005–2010, 2010–2015, and 2015–2020. These elevation change data are derived from the global glacier elevation change product released by Hugonnet et al. (Accelerated global glacier mass loss in the early twenty-first century). For each period, the elevation change data include the elevation change rate in UTM projection (dhdt_UTM), the elevation change rate in geographic coordinate system (dhdt_GCS), and the elevation change rate error in UTM projection (dhdt_err_UTM).\n\nThis dataset can be used to analyze the long-term glacier thinning background in the Jilong ice-rock avalanche source area, to compare changes between the source area and surrounding glaciers, and to provide fundamental data support for research on glacier changes, ice-rock avalanches, and related cryospheric hazards in the Himalayan region.","language":"en","userLimit":null,"instructions":"The data is in GeoTIFF format.
