Beyond SMAP: Can GNSS‐R Platforms Ensure Continuity of Global Soil Moisture Observations?

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract The absence of a definitive follow‐on strategy for the Soil Moisture Active Passive (SMAP) mission, which has already surpassed its planned mission lifetime, presents a significant challenge for the hydrological science community. GNSS‐Reflectometry (GNSS‐R), which exploits reflected satellite navigation signals, has emerged as a rapidly ...

Physically Consistent Reconstruction of Sparse Scatterometer Ocean Surface Wind Fields Based on Physics‐Guided Generative Learning

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Accurate and timely reconstruction of sea surface wind fields from available scatterometer‐derived observations is essential for rapid‐response forecasting and operational oceanography. In this study, we explore a novel physics‐guided generative learning network to reconstruct sea surface wind vector fields directly from sparse scatterometer ...

Estimating Submesoscale‐Driven Particulate Organic Carbon Flux From Remote Sensing at a Dynamic Upwelling Front

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Submesoscale (1–10 km) vertical velocities at fronts enhance the exchange of particulate organic carbon (POC) and heat between the surface ocean and depth. While POC and temperature can be readily assessed in situ, direct quantification of flux remains uncertain due to the observational challenges of measuring submesoscale vertical velocities ...

Ageostrophic Velocities of Curved Ocean Fronts

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Ageostrophic velocities at ocean fronts play a key role in ventilating the upper ocean. The overturning circulation driven by cross‐front ageostrophic flow is widely recognized as the major mechanism of vertical transport, but the role of along‐front ageostrophic velocities remains underrepresented in existing theory.

THE ADVANCED SCATTEROMETER PROCESSING SYSTEM FOR ERS DATA: THIRTEEN YEARS OF OCEAN WINDS FROM SPACE

Gayana, 2004
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.

Validation of Sea Surface Winds From the Space-Borne Radiometer COWVR

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This study aims to validate sea surface wind data derived from the compact ocean wind vector radiometer (COWVR) onboard the International Space Station. The COWVR, a fully polarimetric and two-look microwave radiometer, provides wind direction and speed ...

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.

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 ...

Ten Years of SeaWinds on QuikSCAT for Snow Applications

Remote Sensing, 2010
The scatterometer SeaWinds on QuikSCAT provided regular measurements at Ku-band from 1999 to 2009. Although it was designed for ocean applications, it has been frequently used for the assessment of seasonal snowmelt patterns aside from other terrestrial ...
