Abstract

We describe an investigation that combines space-based observations of glacier parameters with historical glaciological data derived by traditional means to predict changes in ice extent and volume for the Ak-shirak Range in the interior Tien Shan of Central Asia. A variety of geographic information systems and photogrammetric tools are used to extract glacier outlines, derive of a digital elevation model, and compute area versus elevation distribution functions from data acquired by the Advanced Spaceborne Thermal Emission and Reflection radiometer. These products are then used in a glaciological methodology that can predict the response of glacier systems to changes in local climate.
