Performance Analysis of Ocean Surface Topography Altimetry by Ku-Band Near-Nadir Interferometric SAR

Remote Sensing, 2017
Interferometric imaging radar altimeter (InIRA) is the first spaceborne Ku-band interferometric synthetic aperture radar (InSAR) which is specially designed for ocean surface topography altimetry.

Oceanic Spatio‐Temporal Patterns of Vertical Velocities in the Cape Basin and Agulhas Current Retroflection From Two Years of SWOT Altimetry

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Surface Water and Ocean Topography (SWOT) satellite provides a groundbreaking view of sea surface height (SSH) across a 120‐km‐wide swath (20‐km nadir gap), opening new opportunities to reconstruct vertical velocities (w) $(w)$. Vertical motions play a central role in redistributing properties, influencing climate and ecosystems. Using the

Reliability of Extreme Significant Wave Height Estimation from Satellite Altimetry and In Situ Measurements in the Coastal Zone

Journal of Marine Science and Engineering, 2020
Measurements of significant wave height from satellite altimeter missions are finding increasing application in investigations of wave climate, sea state variability and trends, in particular as the means to mitigate the general sparsity of in situ ...

Mechanisms for Meridional Propagation of Global Mesoscale Ocean Eddies Within a PV‐Based Dynamic Framework

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Mesoscale eddies are crucial for global heat and tracer transport, yet the mechanisms underlying their meridional movement remain unclear. Here, we combine satellite observations, idealized numerical experiments, and theoretical modeling to investigate these mechanisms. We demonstrate that the meridional eddy movement is strongly linked to the

Greater Water Surface Variability Revealed by New Congo River Field Data: Implications for Satellite Altimetry Measurements of Large Rivers

Geophysical Research Letters, 2019
Large river hydrodynamics studies inform global and regional issues pertaining to biogeochemical cycling, ecology, water availability, and flood risk. Such studies rely increasingly on satellite measurements, but these are limited by resolution, coverage,

Optimal surface relief reconstruction from both the photometric and the altimetric data [PDF]

Радиофизика и электроника, 2019
Subject and purpose. The paper discusses the extension of the photometric method for the surface relief retrieval from images in the optical and radar wavelengths ranges through the involving of the direct heights measurements by an altimeter onboard the

Parameter estimation for peaky altimetric waveforms [PDF]

, 2013
Much attention has been recently devoted to the analysis of coastal altimetric waveforms. When approaching the coast, altimetric waveforms are sometimes corrupted by peaks caused by high reflective areas inside the illuminated land surfaces or by the ...

The Potential for Leveraging SWOT‐Mapped Uneven Water Surface Elevations to Enhance ICESat‐2–Derived Lake Levels

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Satellite altimetry is advantageous for measuring water surface elevations (WSE) globally. However, biases of time series can be caused by uneven water surfaces, as nadir pointing measurements are often collected at different locations across a lake.

Revealing Coastal Storm‐Wave Transformations From SWOT HR Observation: The English Channel Case Study

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Swell propagation and transformation across variable bathymetry and coastal obstacles fundamentally control nearshore wave energy redistribution, sediment transport, and shoreline evolution. Conventional satellite altimetry cannot adequately resolve these dynamics, particularly refraction and diffraction as swell transition into shallow waters.
