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).

Evidence and Causes of an Unusual Super Plasma Bubble Occurrence During Weak Geomagnetic Conditions Over Europe

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.

Comparative Analysis of Ionospheric Responses to Ultra‐Fast Kelvin Waves With Wavenumbers 1, 2, and 3

Space Weather, Volume 24, Issue 1, January 2026.
Abstract We employed zonal wind data from Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics Doppler Interferometer, equatorial electrojet (EEJ) measurements from Jicamarca (12°S, 77°W), and global ionospheric total electron content (TEC) maps to investigate the effects of ultra‐fast Kelvin waves (UFKW) with zonal wavenumbers 2 and 3 ...
