Abstract. Knowledge of the ice thickness distribution glaciers and caps is an important prerequisite for many glaciological hydrological investigations. A wealth approaches has recently been presented inferring from characteristics surface. With Ice Thickness Models Intercomparison eXperiment (ITMIX) we performed first coordinated assessment quantifying individual model performance. set 17 different models showed that estimates can differ considerably – locally by a spread comparable to...
Abstract. Although worldwide inventories of glacier area have been coordinated internationally for several decades, a similar effort ice thicknesses was only initiated in 2013. Here, we present the third version Glacier Thickness Database (GlaThiDa v3), which includes 3 854 279 thickness measurements distributed over roughly 3000 glaciers worldwide. Overall, 14 % global is now within 1 km measurement (located on same glacier) – significant improvement GlaThiDa v2, covered 6 and 1100...
Knowing the ice thickness distribution of a glacier is fundamental importance for number applications, ranging from planning glaciological fieldwork to assessments future sea-level change. Across spatial scales, however, this knowledge limited by paucity and discrete character available observations. To obtain spatially coherent thickness, interpolation or numerical models have be used. Whilst first phase Ice Thickness Models Intercomparison eXperiment (ITMIX) focused on approaches that...
Direct measurement of the thickness mountain glaciers is difficult over large areas, yet knowledge essential for calculating their volumes and future evolution. We develop a new method estimating ice along glacier flow lines, using “perfect‐plasticity” rheological assumption that relates surface slope to yield stress. Previous studies have used this with shallow‐ice approximation estimate thickness, but standard approach neglects effect side drag on stress balance. Our addresses shortcoming...
Abstract The runoff records of streams draining basins with between 0 and approximately 54% glacier cover, located at the headwaters Urumqi River in eastern Tianshan, central Asia, have been examined for purpose assessing climatic glacial influences on temporal patterns streamflow period 1959–2006. Runoff highest glacierized basin is found to be inversely correlated mass‐balance data increased by 165·1 × 10 4 m 3 or 1·5 times average from 1959 2006, whereas flow a glacier‐free reflects...
Abstract. The direct glaciological method provides in situ observations of annual or seasonal surface mass balance, but can only be implemented through a succession intensive measurements field networks stakes and snow pits. This has contributed to glacier mass-balance being sparse often discontinuous the Tien Shan. Nevertheless, long-term are basis for understanding climate–glacier interactions projecting future water availability glacierized catchments Riegl VZ®-6000 long-range terrestrial...
Abstract Energy exchanges between atmosphere and glacier surface control the net energy available for snow ice melt. Based on meteorological records in Urumqi River Glacier No.1 (URGN1) Chinese Tien Shan during period of 2012–2015, an energy-mass balance model was run to assess sensitivity mass air temperature ( T ), precipitation P incoming shortwave radiation S relative humidity RH wind speed u ) URGN1, respectively. The results showed that melting mainly controlled by radiation. very...
Abstract The Hispar Glacier is a useful site for studying surge mechanisms. Prior to this study, only two‐dimensional (2‐D) flow velocities having low temporal resolution were available glacier, providing inadequate information about its evolution. In 139 synthetic aperture radar (SAR) images from Sentinel‐1A used obtain 3‐D velocity time series the during recent (2014–2016). sampled at an interval of 11 days, which much greater than in previous studies. Besides, Shuttle Radar Topography...
Abstract To investigate the effects of both non-meltwater and meltwater-related post-depositional processes on chemical species within snow–firn pack, a research program, Program for Glacier Processes Investigation, was initiated in July 2002 by Tien Shan Glaciological Station, Chinese Academy Sciences. The seasonal variability ionic concentrations surface snow samples ion elution behavior pack were assessed from collected year-round 1011 pit at weekly intervals September 2003 through 2004....
In April 2023, a major dust storm event in Lanzhou attracted widespread attention. This study provides comprehensive analysis of the causes, progression, and sources this using multiple data methods. Backward trajectory HYSPLIT model was employed to trace origins dust, while FY-2H satellite provided high-resolution distribution patterns. Additionally, MAIAC AOD product used analyze Aerosol Optical Depth, concentration-weighted (CWT) identify key source regions. The found that PM10 played...
Abstract. The glaciers in the Sawir Mountains, Altai area, have been experiencing a continuing and accelerating ice loss since 1959, although snowfall is abundant evenly distributed over year. As an attempt to reduce their melting, we carried out two artificial experiments on Muz Taw Glacier during 19–22 August 2018. We measured albedo mass balance at different sites along glacier before after experiments. Two automatic weather stations (AWSs) were set up equilibrium line altitude (ELA) of...
This study focuses on ice thickness distribution and calculation of the area, terminus, velocity changes Haxilegen Glacier No. 51 in Kuytun River Basin eastern Tianshan Mountains, during 1964–2010. The ground penetrating radar (GPR) survey indicated that maximum mean thicknesses are 73 m 39 for this glacier, respectively. glacier area decreased from 1.48 km2 to 1.32 (10.8%), its terminus retreated with a rate 2.3 a−1 between 1964 2010. change is smallest but it experienced large volume...
Abstract Extreme heat events in the summer of 2022 were observed Eurasia, North America and China. Glaciers are a unique indicator climate change, European Alps experienced substantial glacier mass loss as result conditions 2022, which prompted wide range community concerns. However, relevant findings for glaciers China have not been currently reported. Here, we document response Urumqi Glacier No. 1 eastern Tien Shan to extreme based on situ measurements that span more than 60 years. In...
