A new inventory of High Mountain Asia surging glaciers derived from multiple elevation datasets since the 1970s

Surges are among the main sources of glacier hazards and complete surge-type glacier inventories are required for assessing glacier-related hazards. Glacier surge events in High Mountain Asia (HMA) are widely reported. Through the estimated elevation changes from multiple DEMs sources that acquired since 1970s (KH-9), here we present a new surge-type glacier inventory across HMA. The inventory has incorporated 890 surging and 336 surge-like glaciers during the last four decades (1970s-2020) with assigned indicators of surge possibility. Compared to previous surging glacier inventory in HMA, our inventory is theoretically more complete with the much longer observation period. The inventory is stored in the format of GeoPackage (*.gpkg) and ESRI Shapefile format (*.zip), which is represented by glacier polygon (from GAMDAM2) or centoriod with geometric attributes. Detailed description including the attributes information can be found in the associate metadata file (README.txt).
