Overview

High Mountain Asia stretches from the Tien Shan and Hindu Kush in the northwest, to the eastern Himalaya in the southeast. The region contains one of the highest concentrations of snow and glaciers outside of the polar regions, and the advance or retreat of glaciers in this part of the world provides a window onto Earth's changing climate. In addition, this high-altitude reservoir of ice provides water to more than a billion people. Rapid melt in this region can pose downstream hazards such as glacial lake outburst floods and landslides.

Satellite remote sensing enables scientists to monitor the cryosphere in High Mountain Asia, to better understand Earth system processes, and inform policymaking. These data products will be based on satellite observations, modeling results, and in situ measurements.
