Unveiling the Floodplain River‐Lake Hydrological Interactions by SWOT Observations

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract The bidirectional exchange between rivers and floodplain lakes is critical for regional hydrology, nutrient cycling, and ecosystem management. However, observing the two‐dimensional water surface elevation (WSE) fields that govern these interactions remains a long‐standing challenge, limiting understanding of hydraulic regime shifts.

In Situ Validation of Small‐Scale Spatial Variability in Significant Wave Height Observations From SWOT

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Ocean surface wave climates are shaped by both atmospheric forcing and underlying ocean conditions. Variability in open‐ocean wave heights subsequently reflects complex interactions occurring across a broad range of spatial and temporal scales.

Wide-Swath Altimetric Satellite Data Assimilation With Correlated-Error Reduction

Frontiers in Marine Science, 2020
For decades now, satellite altimetric observations have been successfully integrated in numerical oceanographic models using data assimilation (DA). So far, sea surface height (SSH) data were provided by one-dimensional nadir altimeters.

Braided Rivers From SWOT: Water Surface Dynamics Over the Multi‐Channel Brahmaputra River

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The Surface Water and Ocean Topography (SWOT) satellite can simultaneously observe river elevation, width, and slope with high spatio‐temporal coverage and resolution (Fu et al., 2024, https://doi.org/10.1029/2023gl107652). The River Single‐Pass (RiverSP) product from SWOT provides geolocated river surface water dynamics with global coverage ...

SWOT Unveils the Hidden Hydrodynamics of the Three Gorges Reservoir

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The Three Gorges Reservoir is well known for providing numerous benefits, but has also been fraught with controversy due to environmental issues. Such large channel‐type reservoirs are characterized by significant inflow, long channel shape, and strong backwater, exhibiting unique hydrodynamic characteristics.

First Insights From SWOT Fast Sampling Phase: High Frequency Coastal Trapped Waves Over the Patagonian Shelf

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract The wide and highly productive Patagonian Shelf (PS) hosts a variety of waves. The study of Coastal Trapped Waves with periods smaller than 20 days has been limited by the temporal resolution of satellite altimetric data. The fast sampling phase of the recently launched Surface Water and Ocean Topography (SWOT) satellite revisits specific ...

Parameterization of the Winter Arctic Sea Ice Microwave Emissivity Between 1.4 and 36 GHz, for Large Scale Applications

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract Modeling sea ice microwave emissivities at large scales presents challenges, due to complex interactions between the microwave signal and the sea ice environment. For the preparation of the Copernicus Imaging Microwave Radiometer mission (CIMR) that focusses on the monitoring of polar regions, a pragmatic parameterization of the sea ice ...

Advancing Internal Tide Correction for SWOT Cal/Val: The Role of Ocean Forecasts

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract Internal tides are sub‐surface inertia‐gravity waves that generate significant sea surface height signals detectable with satellite altimetry. The Surface Water and Ocean Topography (SWOT) mission provides an exciting opportunity to characterize these signals with unprecedented spatial detail.
