Dynamics off the Congo River and Its Impact on the Water Exchange Between the Coastal and Open Ocean at Different Timescales

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract The Congo River represents one of the largest freshwater discharges in the Atlantic Ocean. In this study, we investigate the role of mesoscale and submesoscale dynamics in modulating salinity transport, using a 3 km‐resolution realistic numerical simulation.

History Matching of Soil Moisture and Evapotranspiration Over Europe Using Iterative Ensemble Smoothers

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract Land surface models are crucial components within earth system models, simulating the exchanges of water, energy, carbon, and nitrogen between the land surface, atmosphere, and subsurface. One challenge is the large number of uncertain parameters in these models.

Impact of Ocean Currents on Wind Stress in the Tropical Indian Ocean

Remote Sensing, 2022
This study examines the effect of surface currents on the bulk algorithm calculation ofwind stress estimated using the scatterometer data during 2007–2020 in the Indian Ocean. In the study region as a whole, the wind stress decreased by 5.4% by including

Large Drifter Experiment in the Western Mediterranean Sea Reveals Dynamical Versus Noise Contributions in SWOT‐KaRIn Sea Level

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The wide‐swath altimeter Surface Water and Ocean Topography (SWOT) provides unprecedented two‐dimensional sea‐level observations, whose ability to capture upper‐ocean dynamics requires assessment. The dynamically balanced signal and noise contributions in SWOT‐KaRIn Level‐3 (L3) sea level products are here originally quantified and contrasted ...

Scatterometer resolution enhancement [PDF]

IGARSS '98. Sensing and Managing the Environment. 1998 IEEE International Geoscience and Remote Sensing. Symposium Proceedings. (Cat. No.98CH36174), 1998
Scatterometers can be effective for large scale monitoring of the Earth's surface. However, their low resolution can limit the utility of the data. Thus, there is interest in resolution enhancement methods that can create high resolution imagery from scatterometer measurements.

Sensitivity of Tropical Cyclone Forecasts to the Loss of Low Earth Orbit Satellite Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Tropical cyclones are among the most destructive natural hazards, impacting millions of people worldwide each year. Accurate and timely forecasts are therefore essential for effective preparedness and risk mitigation. Forecast skill depends on both the performance of numerical weather prediction models and the observations assimilated into the

Roadmap for leveraging satellite data to advance soil moisture monitoring in Mainland Southeast Asia

Vadose Zone Journal, Volume 25, Issue 3, May/June 2026.
Abstract Soil moisture monitoring is vital for Mainland Southeast Asia (MSEA), a region that plays a pivotal role in global agricultural production. Strong reliance on rain‐fed agriculture, combined with frequent hydroclimatic extremes, makes MSEA one of the world's most climate‐sensitive regions.

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 ...
