Validation of Multisource Altimeter SWH Measurements for Climate Data Analysis in China’s Offshore Waters

Remote Sensing
Climate data derived from long-term, multisource altimeter significant wave height (SWH) measurements are more valuable than those obtained from a single altimeter source.

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.

Retrieving Ocean Surface Winds and Waves from Augmented Dual-Polarization Sentinel-1 SAR Data Using Deep Convolutional Residual Networks

Atmosphere, 2023
Sea surface winds and waves are very important phenomena that exist in the air–sea boundary layer. With the advent of climate change, cascade effects are bringing more attention to these phenomena as warmer sea surface temperatures bring about stronger ...

A Multi-Scale Fusion Deep Learning Approach for Wind Field Retrieval Based on Geostationary Satellite Imagery

Remote Sensing
Wind field retrieval, a crucial component of weather forecasting, has been significantly enhanced by recent advances in deep learning. However, existing approaches that are primarily focused on wind speed retrieval are limited by their inability to ...

On Surface Waves Generated by Extra-Tropical Cyclones—Part II: Simulations

Remote Sensing, 2023
In the previous companion study, satellite data were used to describe peculiar characteristics of ocean surface wave fields, generated by two extra-tropical cyclones (ETCs) rapidly propagating in the North Atlantic.

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 ...

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.
