Enhanced Retrieval of Spring Snow Depth Over Pan‐Arctic Sea Ice From AMSR2 Observations for 2013–2023 Using Multi‐Model Machine Learning

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).

Diagnosing Cryospheric Runoff Dynamics: A Distributed Differentiable Hydrological Model With Global Transfer Learning

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Accurate hydrological prediction in alpine regions remains challenging due to complex cryospheric processes and limited observational records. Traditional hydrological models are often subject to structural uncertainty, whereas purely data‐driven deep learning (DL) models may lack physical interpretability under non‐stationary climate ...

Potentialities and Limits of ICESAT-2 Observation for Atmospheric Aerosol Investigation

EPJ Web of Conferences, 2016
ICESat-2(Ice, Cloud, and land Elevation Satellite-2), slated for launch in 2017, will continue the important observations of ice-sheet elevation change, sea-ice freeboard, and vegetation canopy height begun by ICESat in 2003.

Discrepancy in Satellite Altimetry Products Hinders Robust Retrieval of GIA Signals From Bedrock GNSS Data in Greenland

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Isolating glacial isostatic adjustment (GIA) signals from Global Navigation Satellite System (GNSS) observations of vertical land motion (VLM) in Greenland requires removal of elastic solid Earth response to contemporary ice mass change. This elastic correction depends on ice‐surface elevation changes derived from satellite altimetry and firn ...

SWOT High‐Rate Raster Data Reveals Antarctic Ice Shelf Motion and Change in Response to Ocean and Ice Dynamics

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The NASA/CNES Surface Water and Ocean Topography (SWOT) swath‐mapping radar altimetry satellite mission, launched in December 2022, provides repeat‐track coverage to about ±78.2° latitude every 21 days, sampling many of Antarctica's most dynamic ice shelves that play key roles in constraining mass loss from the grounded ice sheet ...

Rapid Morphological Changes in the Intertidal Zone of the Ganges‐Brahmaputra Delta Revealed by SWOT Altimetry Mission

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Intertidal zones of the Ganges‐Brahmaputra (GB) delta are among the most active coastal environments worldwide, and quantifying their morphological evolution remains challenging due to rapid change and scarce in situ observations. This study presents a satellite‐based direct quantification of intertidal sediment volume change in the Meghna ...

ICESat‐derived inland water surface spot heights [PDF]

Water Resources Research, 2016
AbstractAccurate measurement of water surface height is key to many fields in hydrology and limnology. Satellite radar and laser altimetry have been shown to be useful means of obtaining such data where no ground gauging stations exist, and the accuracy of different satellite instruments is now reasonably well understood.

Mass Loss From Thwaites Glacier Continues Even Without Ocean Melting

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Pine Island and Thwaites glaciers dominate Antarctica's sea‐level contribution. However, it remains unclear whether their ice loss is driven by anomalously warm present‐day ocean conditions, perhaps linked to anthropogenic climate change, or are an ongoing response to historical natural climate anomalies.

Lake Morphometry Influences the Accuracy of SWOT Estimates of Water Level

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Lake water surface elevation (WSE) data in Sweden are needed to understand water supply and ecosystem services provision. SWOT can complement WSE in situ measurements, but the influence of lake shape on its accuracy remains unclear. We explore the performance of the SWOT pixel‐cloud and this influence across 62 lakes from August 2023 to ...
