Updated GAMDAM Glacier Inventory over High Mountain Asia.
Abstract
The original Glacier Area Mapping for Discharge from the Asian Mountains (GAMDAM) glacier inventory was the first methodologically consistent dataset for High Mountain Asia. Nonetheless, the GAMDAM inventory underestimated glacier area as it did not include steep ice- and snow-covered slopes or shaded components. During revision of the inventory, Landsat imagery free of shadow, cloud, and seasonal snow cover was selected for the period 1990-2010, after which > 90% of the glacier area was delineated. The updated GAMDAM inventory, comprising 453 Landsat images, includes 134,770 glaciers with a total area of 100,693 ± 11,790 km2.
