Statistical Model of Subsurface Scattering Bias in ICESat‐2's ATL06 Product
Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract ICESat‐2 uses visible laser pulses and photon‐counting detectors to range the Earth's surface, providing precision altimetry for measuring ice sheet elevation change. However, since water ice is transparent to visible light, the photon returns recorded by ICESat‐2's ATLAS instrument may originate from subsurface scattering inside the snow or ...

Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract Snow on Antarctic sea ice modulates albedo, thermodynamic growth, and snow–ice formation, yet remains a leading uncertainty in altimetry‐derived sea‐ice thickness. Here we use the post‐2022 CRYO2ICE configuration to derive along‐track winter snow thickness from ICESat‐2 laser and CryoSat‐2 Ku‐band radar freeboards over the Weddell and Ross ...

The Impact of Data Resolution on Planetary Compressional Structure Analysis
Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.Abstract Planetary studies of compressional structures are fundamental for understanding the tectonics and thermal evolution of planetary bodies. Compressional features are commonly characterized by their morphology, which in turn is strongly dependent on the spatial resolution of topographic data.

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.Abstract Snow on sea ice modulates the Earth's radiation budget and sea ice mass balance, yet satellite retrievals of Arctic snow depth remain subject to substantial algorithmic uncertainty. We develop a multi‐model machine learning (ML) framework for retrieving spring snow depth over Arctic sea ice from Advanced Microwave Scanning Radiometer 2 (AMSR2).

Sea state and rain: a second take on dual-frequency altimetry [PDF]
, 2004 TOPEX and Jason were the first two dual-frequency altimeters in space, with both operating at Ku- and C-band. Each thus gives two measurements of the normalized backscatter, sigma0, (from which wind speed is calculated) and two estimates of wave height ...

Altimetry-derived surface water data assimilation over the Nile Basin
, 2020 Global hydrological models facilitate studying of water resources and their variations over time. The accuracies of these models are enhanced when combined with ever-increasing satellite remotely sensed data.
