Remote SensingThe Tyrrhenian Sea plays a key role in Mediterranean circulation. However, the seasonal evolution and coastal circulation patterns of its surface circulation remain only partially resolved by previous observations, particularly at mesoscale and ...

Sea surface height measuring using InSAR altimeter
Geodesy and Geodynamics, 2017 Satellite altimetry has been widely used in measuring ocean topography from space. The conventional altimeter system is the nadir radar altimeter system which has the limitations of one-dimensional measurement and is unable to get both high temporal and ...

A Strictly Geostrophic Product of Sea‐Surface Velocities From the SWOT Fast‐Sampling Phase
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract While geostrophy remains the simplest and most practical balance to extract velocity information from sea‐surface height anomaly (SSHa), confusions remain within the oceanographic community to what extent this balance can be applied to altimetric observations with the launch of the Surface Water and Ocean Topography (SWOT) satellite. Given the

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 ...

Assessing Dynamical Contributions to SWOT Sea Surface Height in an Internal Tide Hotspot
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract The Surface Water and Ocean Topography (SWOT) mission has revealed high‐frequency sea surface height anomaly (SSHA) variability associated with internal gravity waves, yet comparison with in situ observations remains limited. Here, we analyze a mooring array beneath the swaths of SWOT Cal/Val south of New Caledonia, an internal tide (IT ...

Estimation of bathymetric depth and slope from data assimilation of swath altimetry into a hydrodynamic model [PDF]
Geophysical Research Letters, 2008 The proposed Surface Water and Ocean Topography (SWOT) mission would provide measurements of water surface elevation (WSE) for characterization of storage change and discharge. River channel bathymetry is a significant source of uncertainty in estimating discharge from WSE measurements, however.

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 ...

SWOT Observations Constrain a 4D‐Var State Estimate of the California Current System
Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract The Surface Water and Ocean Topography (SWOT) mission provides high‐resolution sea surface height (SSH) observations at 2‐km spacing, resolving submesoscale features typical of ageostrophic motions and associated with instabilities. Here, we demonstrate the assimilation of SWOT data into a regional configuration of the MITgcm for the ...
