Lake level elevation and variation are important indicators of regional and global climate and environmental change. Lake Qinghai, the largest saline lake in China, located in the joint area of the East Asian monsoon, Indian summer monsoon, and Westerly jet stream, is particularly sensitive to climate change. This study examines the lake's water level and temporal change using the ice, cloud, and land elevation satellite (ICESat) altimetry data and gauge measurements. Results show that the mean… 

Water balance estimates of ten greatest lakes in China using ICESat and Landsat data

Lake level and area variations are sensitive to regional climate changes and can be used to indirectly estimate water balances of lakes. In this study, 10 of the largest lakes in China, ∼1000 km2 or

Water Level Change of Qinghai Lake from ICESat and ICESat-2 Laser Altimetry

Long-term satellite observations of the water levels of lakes are crucial to our understanding of lake hydrological basin systems. The Ice, Cloud, and Land Elevation satellite (ICESat) and ICESat-2

Heterogeneous change patterns of water level for inland lakes in High Mountain Asia derived from multi‐mission satellite altimetry

High‐altitude inland lakes in High Mountain Asia (HMA) are key indicators to climate change and variability as a result of mostly closed watersheds and minimal disturbance by human activities.

Tibetan Plateau's Lake Level and Volume Changes From NASA's ICESat/ICESat‐2 and Landsat Missions

Lake level change is an effective indicator of climate change, because it reflects the dynamic balance of water input and loss. Here we provide a first look of Ice, Cloud, and land Elevation

Variations in water level and glacier mass balance in Nam Co lake, Nyainqentanglha range, Tibetan Plateau, based on ICESat data for 2003-09

Abstract Water level fluctuations of inland lakes are related to regional-scale climate changes, and reflect variations in evaporation, precipitation and glacier meltwater flowing into the lake area

Investigating Water Variation of Lakes in Tibetan Plateau Using Remote Sensed Data Over the Past 20 Years

This study investigates the water storage changes in 22 lakes in the Tibetan Plateau based on sequential remote sensed lake area and water level derived from moderate resolution imaging spectroradiometer surface reflectance and Laboratoire D’Etudes en Géophysique et Océanographie Spatiales altimetry data, respectively.

Monitoring the Fluctuation of Lake Qinghai Using Multi-Source Remote Sensing Data

This study demonstrates that it is feasible to monitor comprehensively the fluctuation of large water bodies by the combination of satellite altimetry measurements and optical satellite imagery without any in situ measurements.



Lake-Level Change and Water Balance Analysis at Lake Qinghai, West China during Recent Decades

Lake Qinghai, the largest saline lake with an area of 4,260 km2 (2000) and average depth of 21 m (1985) in West China, has experienced severe decline in water level in recent decades. This study

ICESat Observations of Inland Surface Water Stage, Slope, and Extent: a New Method for Hydrologic Monitoring

River discharge and changes in lake, reservoir and wetland water storage are critical terms in the global surface water balance, yet they are poorly observed globally and the prospects for adequate

Satellite‐based assessment of the dynamics of new lakes in southern Egypt

Lakes in arid landscapes are indicators of environmental change and important sources of water for human use. In regions without in situ hydrologic measurements, remote sensing may provide the only
