Deriving Snow Depth From ICESat-2 Lidar Multiple Scattering Measurements: Uncertainty Analyses

Frontiers in Remote Sensing, 2022
The application of diffusion theory and Monte Carlo lidar radiative transfer simulations presented in Part I of this series of study suggests that snow depth can be derived from the first-, second- and third-order moments of the lidar backscattering ...

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.

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 ...

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 ...

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.
