Evaluation of Sea Surface Wind Products from Scatterometer Onboard the Chinese HY-2D Satellite

Remote Sensing, 2023
The Chinese new marine dynamic environment satellite HY-2D was launched on 19 May 2021, carrying a Ku-band scatterometer (named HSCAT-D). In this study, wind products observed by the HSCAT-D were validated by comparing with wind data from the U.S ...

Disentangling Internal Tides From Balanced Motions With Deep Learning and Surface Field Synergy

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract A fundamental challenge in ocean dynamics is disentangling balanced motions and internal waves. Extracting internal tidal (IT) imprints from surface data is a central part of this challenge. Traditional harmonic analysis fails under strong incoherence and poor temporal sampling, as in global satellite observations.

Assimilation of reprocessed ERS scatterometer data into ECMWF weather analysis on the Mediterranean Sea [PDF]

Advances in Geosciences, 2005
Since the launch of ERS-1 in 1991 and ERS-2 in 1995, carrying a C-band Scatterometer, a data set of more than thirteen years of backscattered signal from the Earth surface is available for exploitation.

Satellite Velocity Correction Method of Ocean Current Retrieval for a Spaceborne Doppler Scatterometer

Remote Sensing, 2023
For a spaceborne pencil-beam rotating Doppler scatterometer, its precision in measuring the ocean surface motion depends on the Doppler centroid of the received signals.

One‐Year Long ADCP Data Reveal the Influence of Tides, Winds, and Coastal‐Trapped Waves on the Deep Cross‐Slope Transport in a Submarine Trench

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Submarine canyons and trenches are the main pathways for transport of water, sediments, and nutrients across the continental slope. In the North Sea, transport across the slope and into the Norwegian Sea is confined to the Norwegian Trench (NT).

On the Tropical Nature of an Intense Mediterranean Cyclone in the Ocean‐Atmosphere System

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The Mediterranean basin hosts a large number of cyclones every year. Among them, some rare cases named medicanes present similarities with tropical cyclones but their dynamical characteristics are debated. The ocean‐atmosphere dynamics of Medicane Ianos (2020) are studied here through km‐scale fully coupled ocean‐wave‐atmosphere simulations ...

Potential soil moisture products from the aquarius radiometer and scatterometer using an observing system simulation experiment [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2013
Using an observing system simulation experiment (OSSE), we investigate the potential soil moisture retrieval capability of the National Aeronautics and Space Administration (NASA) Aquarius radiometer (L-band 1.413 GHz) and scatterometer (L-band, 1.260 ...

Interseasonal Hysteresis and Linearity Among Surface Energy Fluxes and Soil Water Content in Observations, Reanalyses, and Model Simulations

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Understanding how surface energy partitioning varies with soil water content (SWC) is crucial to land–atmosphere (LA) coupling. This study evaluates monthly variations in SWC and surface energy budget components across CONUS using in situ observations (OBS) and model‐derived products, including reanalyses (MERRA2 and ERA5) and two CESM ...

Polar‐low track prediction using machine‐learning methods

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 778, July 2026 Part A.
Machine‐learning models are developed to produce reliable and efficient forecasts of polar‐low (PL) trajectories 12 hours ahead. A temporal model (RLSTM) benefiting from the rolling‐forecast strategy, improves overall prediction accuracy and is suitable for quick experimentation, while a spatiotemporal model (PL‐UNet), incorporating both historical and
