Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.Abstract In numerical weather prediction, dynamic initialization (DI) of tropical cyclones (TCs) and bogus data assimilation (BDA) are two widely used vortex initialization methods, both of which substantially affect the track and intensity of simulated TCs.

Validation of Sea Surface Winds From the Space-Borne Radiometer COWVR
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingThis 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 ...

Reconstructing Marine Boundary Layer Jets Over the South China Sea Using Machine Learning
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Marine boundary layer jets (MBLJs) over the South China Sea (SCS) play a critical role in coastal heavy rainfall, yet their structure remains uncertain due to limited wind observations over the ocean. Here, we develop a U‐Net–based reconstruction framework to estimate 950‐hPa winds from satellite‐derived sea surface winds, providing a ...

Atmospheric Science Letters, Volume 27, Issue 6, June 2026.Using 17 years of ensemble‐based forecast sensitivity to observations (EFSO), this study shows that marine meteorological observations in the eastern tropical Indian Ocean have significantly larger impacts during boreal winter than summer, despite similar observation frequencies.

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.

Earth and Space Science, Volume 13, Issue 6, June 2026.Abstract Spaceborne radiometers have enabled global sea‐ice distribution observations since 1978, yet design choices associated with conventional daily averaged remote sensing products mean they do not resolve higher‐frequency variability that characterizes Antarctic sea ice.

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.

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.

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 ...
