Water Storage Changes of Lakes and Reservoirs Across Asia (2018–2023) and Their Effects in Flood Control

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Monitoring lake and reservoir water levels is critical for water resource management and flood risk mitigation. We integrate Sentinel‐3A/B and ICESat‐2 altimetry to reconstruct monthly water levels (2018–2023) for 7,433 lakes and reservoirs (>5 km2) across Asia and estimate their storage variations.

Retrieving Precipitable Water Vapor From Shipborne Multi‐GNSS Observations [PDF]

, 2019
©2019. American Geophysical UnionPrecipitable water vapor (PWV) is an important parameter for climate research and a crucial factor to achieve high accuracy in satellite geodesy and satellite altimetry. Currently Global Navigation Satellite System (GNSS)

Inversion of Seafloor Topography in the Gulf of Mexico Based on Convolutional Neural Network Integrated With Multisource Gravity Data and Bathymetric Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Large-scale, high-precision seabed topography data serves as the foundation for scientific research on Earth’s shape and geological structure. Satellite altimetry data combined with classical gravity field inversion methods are important means for

Stabilized determination of geopotential coefficients by the mixed hom-BLUP approach [PDF]

For the determination of geopotential coefficients, data can be used from rather different sources, e.g., satellite tracking, gravimetry, or altimetry.

The application of Skylab altimetry to marine geoid determination [PDF]

The author had identified the following significant results. The major results can be divided broadly into two groups. One group is concerned with the effects of errors inherent in the various input data, such as the orbit emphemeris, a priori geoid etc.

Performance of SARAL/AltiKa satellite altimetry mission over the Strait of Malacca and the South China Sea [PDF]

, 2015
Satellite altimetry faces challenges when attempting to monitor sea surface heights (SSHs) in coastal zones due to the rapid changes in sea state and land contamination within altimeter footprints.

Comparison of Ocean Dynamics with a Regional Circulation Model and Improved Altimetry in the North-Western Mediterranean

Terrestrial, Atmospheric and Oceanic Sciences, 2008
The spatial and temporal resolution of satellite altimetry is usually sufficient for monitoring the changes of sea surface topography in the open ocean.

Monitoring Continental Surface Waters by Satellite Altimetry

Surveys in Geophysics, 2008
The monitoring of continental water stages is a requirement for meeting human needs and assessing ongoing climatic changes. However, regular gauging networks fail to provide the information needed for spatial coverage and timely delivery. Although the space missions discussed here were not primarily dedicated to hydrology, 18 years of satellite ...

Gravity field, geoid and ocean surface by space techniques [PDF]

Knowledge of the earth's gravity field continued to increase during the last four years. Altimetry data from the GEOS-3 satellite has provided the geoid over most of the ocean to an accuracy of about one meter.
