Impact of Slopes on ICESat-2 Elevation Accuracy Along the CHINARE Route in East Antarctica

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
As the follow-on study to the assessment of ICESat-2 ice surface elevations, we assessed how they are influenced by the surface slopes, which are derived from the ICESat-2 elevations of the received photons and available in the land-ice surface heights ...

A First Look at the Snow/Ice Penetration Effect of SWOT Observations on Water Level of Global Glacial Lakes

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission promises quasi‐global monitoring of glacial lakes, yet the elevation difference arising from its Ka‐band radar penetrating lake snow/ice cover remains unquantified. This poses a challenge to assessing their level changes.

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 ...

ICESat‐2 Pointing Calibration and Geolocation Performance

Earth and Space Science, 2021
ICESat‐2 science requirements are dependent on the accurate real‐time pointing control (i.e., geolocation control) and postprocessed geolocation knowledge of the laser altimeter surface returns. Prelaunch pointing alignment errors and postlaunch pointing

Decadal Erosion Rates and Sediment Buffering Identified Through Enhanced DEM Differencing Using Underutilized Global Satellite DEMs

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract Quantifying decadal‐scale erosion rates in tectonically active regions is essential for assessing landscape hazards and constraining sediment budgets. A key question in Earth surface processes is how contemporary erosion measurements influenced by recent climatic extremes relate to long‐term geological rates.

Backwater Effects From River Ice Jams Observed With SWOT Pixel Cloud Data

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract This study examines the backwater effects from ice jams in Arctic rivers using the Surface Water and Ocean Topography (SWOT) satellite. Ice jams occur when chunks of ice accumulate and obstruct the river flow, causing rapid water level rises and flooding.
