Ocean 2D eddy energy fluxes from small mesoscale processes with SWOT [PDF]

Ocean Science, 2023
We investigate ocean dynamics at different scales in the Agulhas Current system, a region of important interocean exchange of heat and energy. While ocean observations and some of the most advanced climate models capture the larger mesoscale dynamics ...

Observations from the NOAA P-3 aircraft during ATOMIC [PDF]

Earth System Science Data, 2021
The Atlantic Tradewind Ocean-Atmosphere Mesoscale Interaction Campaign (ATOMIC), part of the larger experiment known as Elucidating the Role of Clouds-Circulation Coupling in Climate (EUREC4A), was held in the western Atlantic during the period 17 ...

Measuring Storm Surge with an Airborne Wide-Swath Radar Altimeter

Journal of Atmospheric and Oceanic Technology, 2009
Abstract Over the years, hurricane track forecasts and storm surge models, as well the digital terrain and bathymetry data they depend on, have improved significantly. Strides have also been made in the knowledge of the detailed variation of the surface wind field driving the surge.

A Simulation Experiment on In-Situ Observation of Short-Wavelength Scale Dynamic Processes and Potential Applications to Wide-Swath Interferometric Altimetry Validation

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Short-wavelength (15–150 km) ocean phenomena are difficult to be observed by conventional altimeter due to the sampling method limited the resolution of the data.

Airborne Rain-Rate Measurement with a Wide-Swath Radar Altimeter

Journal of Atmospheric and Oceanic Technology, 2014
Abstract The NOAA Wide-Swath Radar Altimeter (WSRA) uses 80 narrow beams spread over ±30° in the cross-track direction to generate raster lines of sea surface topography at a 10-Hz rate from which sea surface directional wave spectra are produced.

Wide-swath altimetric satellite data assimilation with structured-error detrending

, 2021
For decades now, satellite altimetric observations have been successfully integrated in numerical oceanographic models using data assimilation (DA). So far, sea surface height (SSH) data were provided by one-dimensional nadir altimeters.

Submesoscale oceanic eddy detection in SAR images using context and edge association network

Frontiers in Marine Science, 2022
Oceanic eddies have a non-negligible impact on ocean energy transfer, nutrient distribution, and biological migration in global oceans. The fine detection of oceanic eddies is significant for the development of marine science.

Approaches for Joint Retrieval of Wind Speed and Significant Wave Height and Further Improvement for Tiangong-2 Interferometric Imaging Radar Altimeter

Remote Sensing, 2022
The interferometric imaging radar altimeter (InIRA) adopts a short baseline along with small incidence angles to acquire interferometric signals from the sea surface with high accuracy, thus the wide-swath sea surface height (SSH) and backscattering ...

Rapid Changes in Ocean Surface Waves Across the Eye of Hurricane Milton (2024)

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Two wave buoys deployed in the direct path of Hurricane Milton show a remarkable reduction in significant wave height and peak wave period as the eye of the storm passes and wind speeds are briefly reduced. The rapid adjustment of the waves to the lower wind speeds is initially unexpected, but is explained by the observed changes in the scalar
