AB  - &Emsp; Glacier surges are an unusual undulating instability of ice flow, and a complete inventory of surging glaciers is important for regional mass balance studies and assessment of glacier-related hazards. Glacier surge events in the High Mountains of Asia (HMA) are widely reported. Using estimated elevation changes from multiple DEM sources obtained from the 1970s to 2020, and morphological changes from 1986 to 2021, we present here an inventory of new surge glaciers in the HMA. The inventory includes 890 surging and 336 surge-like glaciers, each assigned metrics for surging characteristics and surge potential. Compared to HMA's previous surge glacier inventory, our inventory is theoretically more complete due to the longer observation period. This data repository contains the surge glacier inventory and maps of glacier elevation change. Inventories are stored in GeoPackage (.gpkg) and ESRI shapefile format (.shp), which is represented by glacier faces (from GAMDAM2) or surface points with geometric attributes. Multi-temporal elevation change maps of identified surge glaciers are divided into 1×1° plots and stored in GeoTiff (*.tif) format. A detailed description of the dataset (including file contents and attribute information) can be found in the metadata file (README.txt).
