Beyond Geostrophic and Gradient Wind: Enhancing the Estimation of Climatic Wind Fields From Radio Occultation

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Wind approximations, such as geostrophic and gradient wind, are limited in their ability to accurately represent atmospheric conditions in the presence of significant planetary wave activity. Those approximations, while widely applied in synoptic‐scale wind field estimation, fail to capture the full complexity of atmospheric dynamics under ...

Quantifying Historical and Future Surface Soil Moisture Drying Using Deep Learning and Remote Sensing

Earth's Future, Volume 14, Issue 3, March 2026.
Abstract Understanding historical and future surface soil moisture (SSM) drying is pivotal due to its close links with droughts, heatwaves, and wildfires, yet debates regarding its evolution persist. In this study, we leverage advanced deep learning techniques to fill gaps of remote sensing‐based SSM data during 1983–2020 and therefore use these gap ...

Near‐Inertial Wave Trapping Inside a Fine‐Scale Anticyclonic Eddy During the BioSWOT‐Med 2023 Cruise: Turbulence and Energy Flux

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Near‐inertial waves (NIWs) are an important source of turbulence for the ocean interior. Mesoscale anticyclonic eddies are known to facilitate their propagation at depth while trapping them. However, in situ observations have so far focused on large (>50 ${ >} 50$ km radius), energetic eddies, whereas most of the ocean is populated by smaller,

Seasonal Circulation, Transport, and Connectivity of the Gerlache and Bransfield Straits Based on 20 Years of SADCP Measurements

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract We use shipboard ADCP data (1999–2018) and a box‐integration approach to study the spatial and seasonal variability that regulates water mass exchanges between the Bellingshausen and Weddell Seas in the northwest Antarctic Peninsula. This system comprises three major currents: the Gerlache Strait Current (GSC), the Bransfield Current (BC), and

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 ...

Phase‐Resolved Attribution of Tropical Cyclone Cold Wakes From an Interpretable Data‐Driven Model

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Tropical cyclones (TCs) generate pronounced sea surface cooling through multiscale air‐sea interactions, yet predicting its full evolution and identifying the governing mechanisms remain challenging. Here we develop TC‐Net, an interpretable deep learning framework that integrates a 3D convolutional encoder with a Transformer bottleneck to ...

Southern Ocean Clear‐Sky Brightening From Sea Spray Aerosol Increase Drives Departure From Hemispheric Albedo Symmetry

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Observations reveal significant negative trends in reflected shortwave radiation over the 21st century. The global‐mean darkening is primarily driven by clouds, while the global‐mean atmospheric clear‐sky signal is near zero due to offsetting trends in the two hemispheres.

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.

Deriving Gridded Soil Moisture Estimates Using Earth Observation Data and a Process Informed Statistical Machine Learning Approach

Meteorological Applications, Volume 33, Issue 1, January/February 2026.
A process‐informed machine learning approach, which included dynamic and static earth observation data and trained on in situ data from the United Kingdom, was capable of reproducing measured in situ values from locations not included in the model training. The model was then employed to derive daily, gridded estimates of soil moisture for Ireland. The

Evaluation of HY-2A Scatterometer Wind Vectors Using Data from Buoys, ERA-Interim and ASCAT during 2012–2014

Remote Sensing, 2016
The first Chinese operational Ku-band scatterometer on board Haiyang-2A (HY-2A), launched in August 2011, is designed for monitoring the global ocean surface wind. This study estimates the quality of the near-real-time (NRT) retrieval wind speed and wind
