Abstract The second Chinese glacier inventory was compiled based on 218 Landsat TM/ETM + scenes acquired mainly during 2006–10. widely used band ratio segmentation method applied as the first step in delineating outlines, and then intensive manual improvements were performed. Shuttle Radar Topography Mission digital elevation model to derive altitudinal attributes of glaciers. boundaries some glaciers measured by real-time kinematic differential GPS or digitized from high-resolution images...
The Gorkha earthquake (magnitude 7.8) on 25 April 2015 and later aftershocks struck South Asia, killing ~9000 people damaging a large region. Supported by campaign of responsive satellite data acquisitions over the disaster zone, our team undertook image survey earthquakes' induced geohazards in Nepal China an assessment geomorphic, tectonic, lithologic controls quake-induced landslides. Timely analysis communication aided response recovery informed decision-makers. We mapped 4312 coseismic...
Abstract A study is presented of the geographical distribution and spatial temporal variabilities western China snow cover in past 47 yr between 1951 1997. The data used consist Scanning Multichannel Microwave Radiometer (SMMR) 6-day snow-depth charts, NOAA weekly extent daily depth number days from 106 selected meteorological stations across China. Empirical orthogonal function was performed on SMMR dataset to better understand pattern variability Qinghai–Xizang (Tibet) cover. multiple...

Abstract. The alteration in river flow patterns, particularly those that originate the Himalaya, has been caused by increased temperature and rainfall variability brought on climate change. Due to impending intensification of extreme events, as predicted Intergovernmental Panel Climate Change (IPCC) its Sixth Assessment Report, it is more essential than ever predict changes streamflow for future periods. Despite fact some research utilised machine-learning- deep-learning-based models...
Abstract Techniques beyond crystal engineering are critical for manufacturing covalent organic frameworks (COFs) and to explore them advanced applications. However, COFs normally obtained as insoluble, unmeltable, thus nonprocessible microcrystalline powders. Therefore, it is a significant challenge implement into larger architectures structural control on different length scales. Herein, facile strategy presented prepare flexible COF nanofiber membranes by in‐situ growth of...

Abstract Based on aerial photographs, topographical maps and the Landsat-5 image data, we have analyzed fluctuations of glaciers in western Qilian Shan, north-west China, from Little Ice Age (LIA) to 1990. The areas volumes whole considered region decreased 15% 18%, respectively, LIA maximum 1956. This trend glacier shrinkage continued accelerated between 1956 These latest decreases area volume were about 10% 34 years. recent may be due either a combination higher temperatures lower...
Abstract Glaciers in China are primarily located the Tibetan Plateau (TP) and surrounding high mountains. The Chinese Glacier Inventory indicates that there 46 377 glaciers western China. Meteorological records indicate air temperature has risen by 0.2˚C per decade since 1951, 1998 was warmest year; precipitation region increased 5–10% from 1953 to 1997. Using remote-sensing Geographic Information System methods, we have monitored changes >5000 over past 50 years. We conclude >80% of...
Abstract Debris cover is widely present in glacier ablation areas of the Tibetan Plateau, and its spatial distribution greatly affects melt rates. High-resolution situ measurements debris thickness on Hailuogou glacier, Mount Gongga, southeastern show pronounced inhomogeneous distribution. An analysis transverse longitudinal profiles indicates that ground-surveyed thicknesses Advanced Spaceborne Thermal Emission Reflection Radiometer (ASTER)-derived thermal resistances layers correlate...
Abstract The degree-day factor (DDF) is an important parameter for the model, which a widely used method ice- and snowmelt computation. Spatial variations of DDF greatly affect accuracy snow- ice-melt modelling. This study analyzes spatial variability DDFs obtained from observed glaciers in different regions western China. results clearly show that single glacier subject to significant small-scale variations, maritime higher than subcontinental extremely continental glaciers. In China...
The fate of the Hindu Kush Himalayan glaciers has been a topic heated debate due to their rapid melting and retreat. underlying reason for is lack systematic large-scale observations extent in region owing high altitude, remoteness terrain, extreme climatic conditions. Here we present remote sensing–based comprehensive assessment current status observed changes glacier Himalayas. It reveals highly heterogeneous, yet undeniable impacts climate change.
Changes of glacial lakes and implications were assessed for the Tian Shan Mountains from 1990 to 2010, based on Landsat Thematic Mapper/Enhanced Mapper Plus images. The total area has expanded greatly over last 20 years, at an average rate 0.69 ± 0.12 km2 a−1 or 0.8 0.1% a−1. Eastern contributed nearly half that increase (≈0.34 0.03 a−1), followed by northern 0.17 Both widespread climate warming glacier shrinking led lake areal expansion, while small medium (<0.6 km2) responded most...
Glacial lake outburst flood (GLOF) is a serious hazard in high, mountainous regions. In the Himalayas, catastrophic risks of GLOFs have increased recent years because most Himalayan glaciers experienced remarkable downwasting under warming climate. However, current knowledge about distribution and changes glacial lakes within central Himalaya mountain range still limited. Here, we conducted systematic investigation entire by using an object-oriented image processing method based on Landsat...
Abstract. To quantify the ablation processes on a debris covered glacier, simple distributed model has been developed and applied to selected glacier. For this purpose, set of field measurements was carried out collect empirical data. A morphometric analysis glacier surface enables us capture statistically areal distribution topographic features that influence thickness consequently ablation. Remote-sensing techniques, using high-resolution satellite imagery, were used extrapolate in situ...
Abstract. To make first-order estimates of the probability moraine-dammed lake outburst flood (MDLOF) and prioritize probabilities breaching posed by potentially dangerous lakes (PDMDLs) in Chinese Himalayas, an objective approach is presented. We first select five indicators to identify PDMDLs according four predesigned criteria. The climatic background was regarded as precondition moraine-dam failure, under different preconditions, we distinguish trigger mechanisms MDLOFs subdivide them...
