Space Weather, Volume 24, Issue 1, January 2026.Abstract Accurate modeling of traveling ionospheric disturbances (TIDs) is essential for characterizing their spatiotemporal variations and mitigating their effects on Global Navigation Satellite System (GNSS) precise positioning. This study develops a regional medium‐scale TID (MSTID) propagation model using BeiDou geostationary orbit (GEO) total ...

Satellites to study geomagnetic storms [PDF]
Eos, Transactions American Geophysical Union, 2007 NASA's Time History of Events and Macroscale Interactions during Substorms (THEMIS) mission to study geomagnetic substorms over the next two years launched on 17 February from Cape Canaveral Air Force Station, Fla. Substorms are visible in the atmosphere as a sudden brightening of polar auroral ribbons as they split and reorganize, and are thought to ...

The Gannon Storm's Impact on Electric and Magnetic Fields in Italy: A Regional Perspective
Space Weather, Volume 24, Issue 1, January 2026.Abstract The intense May 2024 geomagnetic storm provided an opportunity to conduct the first analysis of geoelectric hazards in Italy. Data from three geomagnetic observatories and a magnetotelluric station were analyzed to examine the spatiotemporal evolution of storm‐induced variations.

Global Ionospheric Slab Thickness Prediction Model Using XGBoost and Ensemble Learning
Space Weather, Volume 24, Issue 1, January 2026.Abstract The ionospheric equivalent slab thickness is a key parameter for understanding the plasma distribution in the ionosphere, with direct relevance to satellite navigation, communication, and skywave over‐the‐horizon radar. However, traditional prediction methods often suffer from regional biases, limiting their global applicability.

Freshly Generated Super Sunrise Plasma Bubbles During the Geomagnetic Storm on November 5–6, 2023
Space Weather, Volume 24, Issue 1, January 2026.Abstract During the geomagnetic storm on November 5–6, 2023, freshly generated super sunrise equatorial plasma bubbles (EPBs) and associated irregularities over the 80°–140°E sector were observed combining ground‐based and space observations from GNSS, ionosondes, HF Doppler records, and several satellite missions (COSMIC2, Swarm, and DMSP).

Space Weather, Volume 24, Issue 1, January 2026.Abstract Using data from a cluster of ground‐based global navigation satellite system, we observed spatially extended enhanced ROTI over the European longitudes during a weak geomagnetic storm (Dst ≈ ${\approx} $ −50 nT) on 4 November 2023. The enhanced ROTI is extended over an extensive geographical latitudinal range of 46°N.

ED‐Autoformer: A New Model for Precise Global TEC Forecast
Space WeatherTotal electron content (TEC) is a key parameter for characterizing ionospheric morphology and significantly impacts the Global Navigation Satellite System. The ionosphere responds dramatically to solar and geomagnetic activity, leading to substantial TEC

Space Weather, Volume 24, Issue 1, January 2026.Abstract Geomagnetically induced currents (GICs) are telluric currents driven by space weather that can adversely impact high voltage transformers in electricity supply networks. It is often difficult to obtain transformer GIC data so ground based magnetometer data may be used to estimate the transformer GIC via complex modeling of both network and ...
