 The study aims to provide a detailed analysis of High-Mountain Asia, HMA, Glacier mass loss using satellite data and digital elevation models. The authors generated 5,797 high-resolution DEMs from available submeter commercial stereo imagery and reprocessed 28,278 Aster DEMs over HMA from 2000 to 2018. They combined these observations to generate robust elevation change trend maps and geodetic mass balance estimates for 99% of HMA glaciers between 2000 and 2018. The study estimates total HMA glacier mass change of minus 19.0 plus or minus 2.5 GT year minus 1, minus 0.19 plus or minus 0.03 M year minus 1, and documents the spatial pattern of HMA glacier mass change with unprecedented detail. The results also provide aggregated estimates for HMA glacierized subregions and hydrologic basins, an estimate that the range of excess glacier meltwater runoff due to negative glacier mass balance in each basin constitutes 12 to 53% of the total basin-specific glacier meltwater runoff. These results can be used for calibration and validation of glacier mass balance models, satellite gravimetry observations, and hydrologic models needed for present and future water resource management.
