Surface Change Detection on Venus: An Inter‐Mission Comparison Framework Between Magellan and Future Radar Images

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Detecting surface changes on Venus by comparing Magellan synthetic aperture radar (SAR) data with future high‐resolution data from Envision and VERITAS will be essential for constraining present‐day volcanism and characterizing planetary surface processes.

Fine-Resolution Spaceborne Radar Imaging of Space Targets With Parametric Second-Order Scaling and High-Order Spatial-Variant Phase Compensation

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Spaceborne radar imaging is the key means to obtain the fine-resolution radar image of space targets. However, the nonuniform relative rotational motion caused by the high-speed orbital state leads to the degradation of the radar imaging performance.

Long‐Lived Equatorial Plasma Bubbles Persisting Into the Afternoon Over the Pacific Sector During the Recovery Phase of the April 2023 Geomagnetic Storm

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Equatorial plasma bubbles (EPBs) are typically nighttime ionospheric irregularities, and their persistence into daytime sectors remains insufficiently understood. Here, we investigate long‐lived EPB‐related plasma depletion structures over the Pacific sector during the recovery phase of the 23–25 April 2023 geomagnetic storm using Formosa ...

A New Global Hypsometric Data Set Derived From Satellite and Geometric Methods for Reservoir Storage Estimation

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Reservoir hypsometric relationships are crucial in determining water storage changes and modeling hydrological processes. Previous studies have demonstrated that uncertainties in reservoir surface area observations are a primary source of error in satellite‐derived storage estimates.
