Demonstration of Two Portable Scanning LiDAR Systems Flown at Low-Altitude for Investigating Coastal Sea Surface Topography

open access: yesRemote Sensing, 2011
We demonstrate the efficacy of a commercial portable 2D laser scanner (operating at a wavelength close to 1,000 nm) deployed from a fixed-wing aircraft for measuring the sea surface topography and wave profiles over coastal waters.

An Analytical Method for Dynamic Wave-Related Errors of Interferometric SAR Ocean Altimetry under Multiple Sea States

open access: yesRemote Sensing, 2021
The spaceborne interferometric synthetic aperture radar (InSAR) is expected to measure the sea surface height (SSH) with high accuracy over a wide swath.

Assessing the impact of future altimeter constellations in the Met Office global ocean forecasting system [PDF]

open access: yesOcean Science
Satellite altimeter measurements of sea surface height (SSH) are a crucial component of current operational ocean forecasting systems. The launch of the Surface Water and Ocean Topography (SWOT) wide-swath altimeter (WiSA) mission is bringing a step ...

Streamflow Calibration in Ungauged Basins Using SWOT Discharge and SMAP Surface Soil Moisture Products

open access: yesWater Resources Research, Volume 62, Issue 7, July 2026.
Abstract Significant advances have been made in using terrestrial remote sensing to reduce random errors in land surface models (LSMs). However, less progress has been made in dealing with systematic LSM errors that are instead correlated with true system states.

A Deep Learning Approach to Extract Balanced Motions From Sea Surface Height Snapshot

open access: yesGeophysical Research Letters
Extracting balanced geostrophic motions (BM) from sea surface height (SSH) observations obtained by wide‐swath altimetry holds great significance in enhancing our understanding of oceanic dynamic processes at submesoscale wavelength.

On the retrieval of sea ice thickness and snow depth using concurrent laser altimetry and L-band remote sensing data [PDF]

open access: yesThe Cryosphere, 2018
The accurate knowledge of sea ice parameters, including sea ice thickness and snow depth over the sea ice cover, is key to both climate studies and data assimilation in operational forecasts.

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

open access: yesGeophysical 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

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

open access: yesGeophysical 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.

GNSS-R Altimetry Performance Analysis for the GEROS Experiment on Board the International Space Station

open access: yesSensors, 2017
The GEROS-ISS (GNSS rEflectometry, Radio Occultation and Scatterometry onboard International Space Station) is an innovative experiment for climate research, proposed in 2011 within a call of the European Space Agency (ESA).

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

open access: yesGeophysical 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.
