Understanding uncertainties in the satellite altimeter measurement of coastal sea level: insights from a round-robin analysis [PDF]

open access: yesOcean Science
The satellite radar altimetry record of sea level has now surpassed 30 years in length. These observations have greatly improved our knowledge of the open ocean and are now an essential component of many operational marine systems and climate studies ...

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

open access: yesWater 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 ...

Estimating Baseline Flow Resistance Parameters for Remote Sensing River Discharge (RSQ) From River Morphology Characteristics

open access: yesJAWRA Journal of the American Water Resources Association, Volume 62, Issue 4, August 2026.
ABSTRACT This study demonstrates that flow resistance in rivers, quantified via calibration of a modified Manning's equation, can inform its estimation from channel hydrometric information available from regional or global datasets for a limited set (N = 14) of rigorously calibrated river reaches in Alaska and with less certainty in a large set (N ...

On the Tropical Nature of an Intense Mediterranean Cyclone in the Ocean‐Atmosphere System

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The Mediterranean basin hosts a large number of cyclones every year. Among them, some rare cases named medicanes present similarities with tropical cyclones but their dynamical characteristics are debated. The ocean‐atmosphere dynamics of Medicane Ianos (2020) are studied here through km‐scale fully coupled ocean‐wave‐atmosphere simulations ...

Multi-Satellite Altimeter Validation along the French Atlantic Coast in the Southern Bay of Biscay from ERS-2 to SARAL

open access: yesRemote Sensing, 2018
Monitoring changes in coastal sea levels is necessary given the impacts of climate change. Information on the sea level and its changes are important parameters in connection to climate change processes.

Ice Sheet Elevation Change in West Antarctica From Ka‐Band Satellite Radar Altimetry

open access: yesGeophysical Research Letters, 2019
Satellite altimetry has been used to track changes in ice sheet elevation using a series of Ku‐band radars in orbit since the late 1970s. Here, we produce an assessment of higher‐frequency Ka‐band satellite radar altimetry for the same purpose, using ...

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

open access: yesGeophysical 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 ...

Compensating Changes in the Penetration Depth of Pulse-Limited Radar Altimetry Over the Greenland Ice Sheet

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2019
Changes in firn properties affect the shape of pulse-limited radar altimeter echoes acquired over the polar ice sheets. We apply a waveform deconvolution model to CryoSat-2 low-resolution mode echoes to determine the depth distribution of radar ...

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

open access: yesGeophysical 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 ...

Effects of Interferometric Radar Altimeter Errors on Marine Gravity Field Inversion

open access: yesSensors, 2020
The traditional altimetry satellite, which is based on pulse-limited radar altimeter, only measures ocean surface heights along tracks; hence, leads to poorer accuracy in the east component of the vertical deflections compared to the north component ...
