High Mountain Asia (HMA) hosts the largest glacier concentration outside of polar regions. It is also distinct glaciologically as it forms one two major surge clusters globally, and many glaciers there contradict globally observed recession trend. Surging are critical to our understanding HMA dynamics, threshold behaviour flow instability, hence have been subject extensive research, yet dynamic...

the presence of glacial deposits is among the most important evidences of quaternary climatic changes. the aalamkooh and thakht-e-solieman glaciers are the samples of those glaciers in the alborz mountains. all iranian and foreign researchers who have worked on the alamkooh glaciers believe the glaciers of northern alborz are parts of active ones in iran. the objective of this research is inves...

Deposited mineral dust and black carbon are known to reduce the albedo of snow and enhance melt. Here we estimate the contribution of anthropogenic black carbon (BC) to snowmelt in glacier accumulation zones of Central Asia based on in-situ measurements and modelling. Source apportionment suggests that more than 94% of the BC is emitted from mostly regional anthropogenic sources while the remai...

A comparative analysis is presented for empirical topographic normalization of Landsat Thematic Mapper (TM) data in varied forest and topographic settings. The paired study included rugged areas of Glacier National Park, Montana, Linville Gorge Wilderness, North Carolina, and Green Mountains, Vermont, U.S.A. Empirical models of topographic bias achieved significant corrections in the Montana an...
