New Observations From the SWIM Radar On-Board CFOSAT: Instrument Validation and Ocean Wave Measurement Assessment

IEEE Transactions on Geoscience and Remote Sensing, 2020
This paper describes first results obtained from the SWIM (Surface Waves Investigation and Monitoring) instrument carried by CFOSAT (China France Oceanography Satellite), which was launched on October 29th, 2018. SWIM is a Ku-Band radar with a near-nadir

Estimation and Correction of Geolocation Errors of the CFOSAT Scatterometer Using Coastline Backscatter Coefficients

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The scatterometer onboard the China-France Oceanography Satellite (CFOSAT) is the first rotating fan beam scatterometer (CSCAT) in operation. It is used to measure the ocean surface wind fields over a large observation swath.

Detailed Monitoring of the Antarctic Marginal Ice Zone by Satellite Radar Altimeter Synergy—A Study of the Weddell Sea/Indian Ocean Sector in July 2017

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The wave‐affected Marginal Ice Zones (MIZ) is a key region of air‐ice‐ocean interactions in the Southern Ocean (SO). However, challenges still remain for the large‐scale observation of the MIZ. In this study, we use four concurrent radar altimeters to retrieve the wave‐affected MIZ in the eastern Weddell Sea‐Indian Ocean sector, which was ...

Statistical Comparison of Ocean Wave Directional Spectra Derived From SWIM/CFOSAT Satellite Observations and From Buoy Observations

IEEE Transactions on Geoscience and Remote Sensing, 2022
The comparison and verification of ocean wave spectrum by remote sensing and in situ measurements at the spectral level are quite rare because the use of the traditional comparison method leads to very limited spatiotemporal matching pairs.

Observing Interactions Between Waves, Winds, and Currents From SWOT

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract The Surface Water and Ocean Topography (SWOT) satellite mission enables, for the first time, two‐dimensional (2D) mapping of significant wave height Hs $\left({H}_{s}\right)$ at kilometer‐scale resolution. Using data from SWOT's Ka‐band Radar Interferometer (KaRIn), this study investigates interactions between surface waves, winds, and ...

Benefits of the Adaptive Algorithm for Retracking Altimeter Nadir Echoes: Results From Simulations and CFOSAT/SWIM Observations

IEEE Transactions on Geoscience and Remote Sensing, 2021
The accuracy of sea surface parameters retrieved from altimeter missions is predominantly governed by the choice of the so-called “retracking” algorithm, i.e., the model and inversion method implemented to obtain the surface parameters from the ...

Insight on the Coastal Response to Combined Tides, Storm Surges, and Surface Waves in a Macrotidal Bay From Real‐Time Predictions

Journal of Geophysical Research: Oceans, Volume 130, Issue 9, September 2025.
Abstract Hazardous sea surface conditions can develop during storm events, when wind‐generated waves and storm surges coincide with high astronomical tides. For better understanding of these conditions, a novel and computationally efficient real‐time forecast model (COASTLINES‐BoF) was developed for a macrotidal bay that is exposed to wind waves, the ...

Coastal Flooding in Asian Megadeltas: Recent Advances, Persistent Challenges, and Call for Actions Amidst Local and Global Changes

Reviews of Geophysics, Volume 62, Issue 4, December 2024.
Abstract Asian megadeltas, specifically the Ganges‐Brahmaputra‐Meghna, Irrawaddy, Chao Phraya, Mekong, and Red River deltas host half of the world's deltaic population and are vital for Asian countries' ecosystems and food production. These deltas are extremely vulnerable to global change. Accelerating relative sea‐level rise, combined with rapid socio‐
