Impacts of the May 2024 G5 Storm on the Earth’s Upper Atmosphere: A Multi‐Instrument and Modeling Study

Space Weather, Volume 24, Issue 11, November 2026.
Abstract Understanding the coupled ionosphere‐thermosphere response to extreme geomagnetic storms is essential for improving physical understanding and space weather forecasting. We investigated the May 2024 G5 geomagnetic storm using observations from ionosondes, COSMIC‐2, Swarm, and GRACE‐FO satellites, GNSS total electron content (TEC) networks, and

Deep Learning—Based Airglow Fusion and Forecasting for Equatorial Plasma Bubble Monitoring and GNSS Scintillation Prediction

Space Weather, Volume 24, Issue 11, November 2026.
Abstract Equatorial plasma bubbles (EPBs) are major low‐latitude ionospheric irregularities that can cause scintillation and degrade Global Navigation Satellite System (GNSS) performance. Existing amplitude‐scintillation prediction methods primarily use historical GNSS observations and ionospheric parameters, but rarely incorporate the evolving spatial

Tomographic imaging of equatorial plasma bubbles

, 2006
Recently the Global Ultraviolet Imager (GUVI) on‐board the Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) satellite has detected far ultraviolet (FUV) images of plasma depletions in the low‐latitude and equatorial ionosphere.

Long‐Term Increase in Equatorial Rayleigh‐Taylor Instability: Synergistic Effects of Greenhouse Gas Cooling and Geomagnetic Field Secular Variation

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Equatorial plasma bubbles (EPBs) are ionospheric irregularities generated by Rayleigh–Taylor instability (RTI) that disrupt satellite communications. We quantify secular change of RTI growth rates and isolate underlying drivers using WACCM‐X simulations.

Field-aligned scale length of depleted structures associated with post-sunset equatorial plasma bubbles

Journal of Space Weather and Space Climate, 2023
In this study we make use of the Swarm counter-rotation constellation for estimating the typical scale length of the post-sunset equatorial plasma bubbles (EPBs) along fluxtubes.

Enhancement of Magnetic Flux Transferred to the Magnetotail Due to a Storm‐Time Kelvin‐Helmholtz Instability

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Along the flank magnetopause, magnetosheath flow interfaced with the relatively stationary magnetosphere produces strong flow shears, and the Kelvin‐Helmholtz instability (KHI) occurs. When the interplanetary magnetic field (IMF) is southward, anti‐parallel day‐side reconnection and KHI can interact, which may enhance the reconnection rate as ...

Dynamic Evolution of a Storm‐Time “Super‐EPB” Event Over China on the Magnetically Disturbed Night of 01 December 2023

Space Weather, Volume 24, Issue 10, October 2026.
Abstract This paper investigates the dynamic evolution of a storm‐time “Super‐EPB” event over China on 1 December 2023 (Kp ≤ 7, SYM/H ≥ −130 nT) using multi‐instrument observations. Occurring near sunset as the IMF‐Bz abruptly turned southward, with auroral extension to midlatitudes, the “Super‐EPB” extended to 40°N with an apex height of ∼2,460 km ...

Scintillations in Southern Europe During the Geomagnetic Storm of June 2015

Remote Sensing
The sensitivity of Global Navigation Satellite System (GNSS) receivers to ionospheric disturbances and their constant growth are nowadays resulting in an increased concern of GNSS users about the impacts of ionospheric disturbances at mid-latitudes.
