Determination of the lunar body tide from global laser altimetry data [PDF]

, 2020
We use global data from the Lunar Orbiter Laser Altimeter (LOLA) to retrieve the lunar tidal Love number h2 and find h2 = 0.0387 ± 0.0025. This result is in agreement with previous estimates from laser altimetry using crossover points of LOLA profiles ...

Multicriteria Selection of Elevation Control and Image Tie Points for Block Adjustment of ZY-3 Images and ICESat Data in Antarctica

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Integrating optical satellite images and laser altimetry data is essential to achieve high-accuracy mapping, especially in areas without ground control points.

Toward Constraining Ocean Estimates in Ice‐Covered Regions Using Sea Level Altimetry Data

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Estimates of ice‐covered oceans are difficult to constrain using in situ observations, particularly if one needs broad spatiotemporal coverage of subsurface properties. Here we explore the value of sea level (ζ $\zeta $) data from the laser altimeter on ICESat‐2 and multi‐mission radar altimeter products distributed by the Archiving ...

Meso‐ to Submesoscale Variability of Particulate Carbon Export Captured by a Glider‐Camera System in the Northeast Atlantic During the APERO Campaign

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Between 9 June and 6 July 2023 a SeaExplorer glider equipped with an Underwater Vision Profiler (UVP6), surveyed frontal structures between a cyclonic and two anticyclonic eddies in the Northeast Atlantic as part of the APERO cruise (Assessing marine biogenic matter Production, Export and Remineralization: from the surface to the dark Ocean ...

Origin of Late Noachian‐Early Hesperian Valley Networks on Mars: Insights From Landform Evolution and Ice Sheet Modeling

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Dendritic valley networks on Mars have been cited as evidence for a warm and wet Noachian Mars, permitting rainfall precipitation and surface runoff. However, the climatic conditions required to sustain rainfall on early Mars remain debated.

Introducing Regularization Constraints Into Combination of GRACE Monthly Terrestrial Water Storage Changes

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Gravity Recovery and Climate Experiment (GRACE) observation data processed by various institutions yields somewhat different spherical harmonic solutions, which are further used to derive terrestrial water storage (TWS) changes. Combining TWS solutions from different institutions helps to refine the effective signal while removing noise.

Assessment of SWOT for Monitoring Ice‐Marginal Lake Water Levels in Greenland

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Surface Water and Ocean Topography (SWOT) satellite mission provides a powerful data set for monitoring global surface water resources. However, its performance for monitoring ice‐marginal lakes in Greenland remains unknown. Due to the scarcity of in situ measurements, this study evaluated the reliability of ice‐marginal lake elevations ...

Icesat full waveform altimetry compared to airborne laser altimetry over the Netherlands

, 2007
Since 2003 the spaceborne laser altimetry system on board of NASA’s Ice, Cloud and land Elevation Satellite (ICESat) has acquired a large world-wide database of full waveform data organized in 15 products.
