The GAMDAM glacier inventory: a quality-controlled inventory of Asian glaciers [PDF]

The Cryosphere, 2015
We present a new glacier inventory for high-mountain Asia named "Glacier Area Mapping for Discharge from the Asian Mountains" (GAMDAM). Glacier outlines were delineated manually using 356 Landsat ETM+ scenes in 226 path-row sets from the period 1999–2003,

A Systematic, Regional Assessment of High Mountain Asia Glacier Mass Balance

Frontiers in Earth Science, 2020
High-mountain Asia (HMA) constitutes the largest glacierized region outside of the Earth's polar regions. Although available observations are limited, long-term records indicate sustained HMA glacier mass loss since ~1850, with accelerated loss in recent

Landslide Hazard Is Projected to Increase Across High Mountain Asia

Earth's Future
High Mountain Asia has long been known as a hotspot for landslide risk, and studies have suggested that landslide hazard is likely to increase in this region over the coming decades.

Exploring the Utility of Machine Learning-Based Passive Microwave Brightness Temperature Data Assimilation over Terrestrial Snow in High Mountain Asia

Remote Sensing, 2019
This study explores the use of a support vector machine (SVM) as the observation operator within a passive microwave brightness temperature data assimilation framework (herein SVM-DA) to enhance the characterization of snow water equivalent (SWE) over ...

Warming, increase in precipitation, and irrigation enhance greening in High Mountain Asia

Communications Earth & Environment, 2022
Greening in high mountain Asia between 2003 and 2020 was driven by warming at high elevations, increased precipitation in forested regions and enhanced irrigation in croplands, according to a multivariate analysis of remote sensing data.

Constructing dataset of classified drainage areas based on surface water-supply patterns in High Mountain Asia

Big Earth Data, 2020
The High Mountain Asia (HMA) region, ranging from the Hindu Kush and Tien Shan in the west to the Himalaya in the south with an altitude between 2000 and 8844 m, holds the largest reservoir of glaciers and snow outside Earth Polar Regions.

Reversed Surface-Mass-Balance Gradients on Himalayan Debris-Covered Glaciers Inferred from Remote Sensing

Remote Sensing, 2020
Meltwater from the glaciers in High Mountain Asia plays a critical role in water availability and food security in central and southern Asia. However, observations of glacier ablation and accumulation rates are limited in spatial and temporal scale due ...

Will high heatwave risk be the new normal over high-elevation regions of northwestern High Mountain Asia in the future?

Environmental Research Communications
The rise in temperature as a consequence of climate change has significantly impacted the environmental, social, and economic systems worldwide, especially over complex terrains like High Mountain Asia (HMA). Assessment of the associated climate risks is

Pond Dynamics and Supraglacial-Englacial Connectivity on Debris-Covered Lirung Glacier, Nepal

Frontiers in Earth Science, 2017
The hydrological systems of heavily-downwasted debris-covered glaciers differ from those of clean-ice glaciers due to the hummocky surface and debris mantle of such glaciers, leading to a relatively limited understanding of drainage pathways ...

Contrasting Centennial‐Scale Climate Variability in High Mountain Asia Revealed by a Tree‐Ring Oxygen Isotope Record From Lahaul‐Spiti

Geophysical Research Letters, 2020
Glacier response analyses in High Mountain Asia have revealed that the glaciers from the Karakoram region were in balance or thickening while most from the other regions were thinning, the “Karakoram anomaly.” It is, however, not clear whether this ...
