Influence of Ocean Currents on Wave Modeling and Satellite Observations: Insights From the One Ocean Expedition

Journal of Geophysical Research: Oceans, Volume 129, Issue 11, November 2024.
Abstract This study investigates the influence of ocean currents on wave modeling and satellite observations using in situ wave measurements from the One Ocean Expedition 2021–2023. In January 2023, six OpenMetBuoy drifters were deployed in the Agulhas Current region.

Australian Ocean surface waves dataset from SAR

Geoscience Data Journal, Volume 11, Issue 4, Page 638-654, October 2024.
In this article, a first regional Synthetic Aperture Radar (SAR) ocean surface waves dataset, containing directional ocean swell spectra measurements from Europe's Sentinel‐1 A and B satellites, is described. The goal is to support marine scientific and industrial research in Australia.

What Can Hurricane Sam (2021) Tell Us About Extreme Ocean Waves Under Tropical Cyclones?

Journal of Geophysical Research: Oceans, Volume 129, Issue 8, August 2024.
Abstract We investigate the ocean wave field under Hurricane Sam (2021). Whilst measurements of waves under Tropical Cyclones are rare, an unusually large number of quality in situ and remote measurements are available in that case. First, we highlight the good consistency between the wave spectra provided by the Surface Waves Investigation and ...

Retrieval of the two-dimensional slope field by the SWIM spectrometer of the CFOSAT satellite: discussion of the algorithm

Russian Journal of Earth Sciences, 2022
In October 2018, the Chinese-French satellite CFOSAT was launched into low-earth orbit, which carries the French SWIM spectrometer and the Chinese scatterometer RFSCAT. The SWIM (Ku-band) spectrometer measures the normalized radar cross section (NRCS) at

Along‐Track Resolution and Uncertainty of Altimeter‐Derived Wave Height and Sea Level: Re‐Defining the Significant Wave Height in Extreme Storms

Journal of Geophysical Research: Oceans, Volume 129, Issue 6, June 2024.
Abstract Satellite altimeters are the most common source of wave measurement in phenomenal sea states, with significant wave heights exceeding 14 m. Unfortunately their data is still considered with skepticism, because there is usually no other data to verify the accuracy of the largest values.

Reconstruction of Wide Swath Significant Wave Height From Quasi‐Synchronous Observations of Multisource Satellite Sensors

Earth and Space Science, Volume 11, Issue 5, May 2024.
Abstract Global sea wave monitoring is of utmost importance for tasks such as analysis of ocean climate change, offshore fisheries, and early warning of marine disasters. Significant wave height (SWH) is one of the most vital and widely used metrics for measuring sea waves in marine research.
