High‐Precision Prediction of Auroral Substorm Expansion Phase Evolution Using a Spatio‐Temporal Attention Deep Learning Model

Space Weather, Volume 24, Issue 2, February 2026.
Abstract Auroral substorms are a key manifestation of solar‐terrestrial interactions and the release of energy within the Earth's magnetosphere. The expansion phase, which is characterized by rapid changes in auroral morphology and intensity, poses significant space weather risks to satellite operations and communication systems.

AI‐Based Improvement of IRI‐2020 Electron Density Profiles With COSMIC Radio Occultation Data

Space Weather, Volume 24, Issue 2, February 2026.
Abstract In this study, we propose an AI‐based method to improve the electron density profiles generated by the International Reference Ionosphere (IRI)‐2020 model using the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) radio occultation (RO) data.

High‐Latitude Electrodynamics and Thermospheric Density Variations During the 2024 Gannon Storm

Space Weather, Volume 24, Issue 2, February 2026.
Abstract This study investigates high‐latitude electrodynamics and thermospheric density variations during the 2024 Gannon's storm. First, the auroral precipitation module of Auroral Spectra and High‐Latitude Electric field variabilitY, ASHLEY‐A, is improved to more accurately capture the location of auroral precipitation observed during this ...

Data‐Driven Satellite Drag Modeling Without Dynamic Knowledge of the Atmosphere

Space Weather, Volume 24, Issue 2, February 2026.
Abstract Increasing congestion in low Earth orbit (LEO) from new satellite deployments and a growing debris population has made accurate orbital trajectory prediction essential for anticipating and avoiding potential collisions on a regular basis. Atmospheric drag is usually the dominant source of propagation error across much of LEO, especially during

The Non‐Linear Dependence of Daily Maximum Ionospheric Total Electron Content on F10.7

Space Weather, Volume 24, Issue 2, February 2026.
Abstract Daily 10.7 cm solar flux, the F10.7 index, is a key parameter for the ionospheric state. Global maps of ionospheric Total Electron Content (TEC) offer almost continuous multidecadal coverage. We find that the global daily maximum of TEC saturates with daily F10.7.

Revised History of Pleistocene Vertical Motions in NE Sicily and Southern Calabria, Italy, From 40Ar/39Ar Dating and Fault Zone Morphology

Tectonics, Volume 45, Issue 2, February 2026.
Abstract Long‐term rates of crustal uplift in southern Calabria and NE Sicily are incompletely understood due to limited information about the age of marine terraces at 1.0–1.3 km above sea level (asl). This study provides a new constraint on high‐elevation terrace ages through integrated analysis of geochronology, stratigraphy, shoreline modeling, and
