Summary: The study developed a two-dimensional mass balance model to investigate the spatially distributed glacier surface energy and mass fluxes in the Western Himalaya. Results showed that net radiation is the major contributor to total energy during the melt season, while sensible heat, latent heat, and ground heat fluxes have smaller contributions. Sensitivity analysis indicated that albedo and surface radiations are highly sensitive factors affecting glacier mass balance in the study area.

Summary: The number and area of alpine lakes in Tien Shan are rapidly growing, mainly due to a warming climate and retreating glaciers. Glacial lakes continuously increased in size, while non-glacial lakes expanded intermittently. Proglacial lakes and extraglacial lakes showed the highest expansion rates among the four types of alpine lakes.

Summary: Remote sensing techniques are used to estimate hydrological variables such as evapotranspiration, which should be carefully interpreted to provide practical information. This study compared the results of two remote sensing studies, finding that actual water use is generally higher than irrigation requirements, indicating potential overirrigation.

Summary: Proglacial lakes in the Himalayan region are expanding due to climate change and are destabilizing glaciers, particularly the Dulung Glacier, which shows higher rates of melting and degeneration compared to the adjacent land-terminating Chilung Glacier. The expansion of the proglacial lake is accompanied by increased mass losses and reduced ice velocity of the Dulung Glacier, indicating its greater sensitivity to climate change. If the current rate of expansion continues, it will further accelerate the degeneration of the Dulung Glacier.

Summary: A remote sensing-derived lake ice phenology database covering all lakes in Alaska from 2000 to 2019 was constructed to analyze the trends of earlier breakup and later freezeup of lake ice in the region. The dataset showed significant trends towards earlier or later ice breakup and freezeup for various lakes, with most significant trends observed in lakes north of the Brooks Range. This dataset contributes to the understanding of interactions between lake processes and climate change, supporting research on biogeochemical, limnological, and ecological regimes in Alaska and pan-Arctic regions.

Summary: This study developed and applied a new approach to calibrate hydrological models using distributed geospatial remote sensing data in the Lake Chad Basin in Africa. Through sensitivity analysis and optimization of influential parameters, the model performance was significantly improved. The new approach of using remote sensing ETa for a limited period of time showed robustness and good performance.

Summary: A novel integrated approach utilizing spectral information and thermal data from satellite images, along with geomorphometric parameters, is proposed for classifying SGD and PGD in the Chandra River Basin of the western Himalayas. The accuracy of the classified data is validated, with SGD accurately delineated with 93% accuracy and an overall classification accuracy of 83.50%.

Summary: Glacier-associated hazards, particularly glacial lake outburst floods (GLOFs), pose a common and serious threat to high mountainous regions worldwide. This study focused on analyzing the dynamics and susceptibility of a selected glacial lake in the Satluj basin of the Western Himalayas using Landsat and Google earth imagery. The results show an increase in lake area and a high susceptibility index, indicating the potential for GLOFs. The study also assessed the impact on downstream areas and highlights the urgency to monitor and assess such lakes to mitigate the disastrous consequences.

Summary: The Sikkim Himalayan glaciers and glacial lakes are experiencing the impact of climate change, leading to an increase in the total lake area, particularly in the Gurudongmar lake complex. Climate change and ongoing glacier retreat are the main factors contributing to the expansion of the lake areas, with changes in precipitation levels affecting the expansion velocity of the glacial lakes.

Summary: The study revealed that glaciers in the Hindu-Kush Himalaya region have a large amount of debris cover in the ablation zone, which significantly slows down the ablation rate due to the increased thickness of supraglacial debris. Field measurements showed that approximately 15% of Chandra Basin is covered by supraglacial debris, with up to 90% debris cover in the ablation area of the studied glaciers.

Summary: The study reveals the hydrological characteristics of the Chandra River in the upper Indus basin, with significant impacts of summer air temperature and winter precipitation on river discharge. Groundwater, glacier melt, and seasonal snowmelt are identified as the main sources of river runoff. Additionally, the study establishes a linkage between seasonal snowmelt, glacier melt, groundwater, and river runoff.

Summary: This study evaluates the accuracy of Landsat8 OLI, Sentinel-1A, and GF images in delineating debris-covered glaciers in the Eastern Tomur Peak Region (EPTR) of the Tien Shan Mountain. The results show that these images have high accuracy in delineating debris-covered glaciers, with F1 scores of 96.73%, 93.55%, and 95.81%, respectively. The analysis of area change using Landsat images from 2000 to 2022 reveals a decrease in glacier area and an increase in debris-covered area, confirming the inhibitory effect of debris on glacier melting. The main driver of change in debris-covered glaciers is the increase in temperature.

Summary: Ice masses and snow of Hunza River Basin are crucial sources of fresh water for downstream inhabitants, but are significantly affected by changing climatic conditions. While the overall glacier area in HRB decreased from 1990 to 2018, there was a period of growth observed from 2009 to 2015. The glaciers in HRB are relatively stable compared to other regions, but are still vulnerable to climate change impacts.
