Evolution of Ionospheric Ion Upflow Flux During the April 2023 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract We study the impact of the evolving magnetosphere‐ionosphere‐thermosphere system on upward ion fluxes during the 23–24 April 2023 geomagnetic storm. This storm has a “double‐dip” structure where two southward IMF Bz ${\mathrm{B}}_{z}$ periods cause two dips in the SYM‐H index.

The Influence of Geomagnetic Storm of 7‐8 September 2017 on the Swarm Precise Orbit Determination

Journal of Geophysical Research: Space Physics, 2019
We analyze a recent geomagnetic storm event on 7‐8 September 2017 to investigate the impact of geomagnetic storm on the precise orbit determination (POD) of Swarm constellation. The storm time performance of POD is analyzed.

Torsional Alfvén Wave Embedded ICME Magnetic Cloud and Corresponding Geomagnetic Storm [PDF]

Astrophysical Journal, 2018
Energy transfer during the interaction of large-scale solar wind structure and the Earth’s magnetosphere is a chronic issue in space-weather studies. To understand this, researchers widely studied the geomagnetic storm and substorm phenomena. The present

Climatology of Medium‐Scale Traveling Ionospheric Disturbances Over Continental US Using GNSS TEC From 2012 to 2023

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Medium‐Scale Traveling Ionospheric Disturbances (MSTIDs) have long been a subject of interest in ionospheric research. However, their spatiotemporal variability across regions, local times, seasons, and solar cycles is very complicated and remains not well established.

Enhanced Radiation Exposure of Airline Crew and Passengers During the May 2024 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Enhanced radiation at aviation altitudes is a concern for flight crew and passengers. During space weather events, solar flares and coronal mass ejection (CME) driven shocks are sources of energetic particles that can reach Earth's near‐space environment and interact with its magnetic field and atmosphere.

A Safety Evaluation Method for a Power System Influenced by a Geomagnetic Storm

IEEE Access, 2020
Geomagnetic storm disasters have a significant impact on the safe and stable operation of power systems. Serious geomagnetic storm disasters can lead to cascading accidents in power systems, up to and including voltage collapse accidents.

Longitudinal Variability of Pre‐Midnight Equatorial Plasma Bubbles Under Disturbed Geomagnetic Conditions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Equatorial plasma bubbles (EPBs) pose significant challenges to trans‐ionospheric radio communication and navigation systems. Because of their disruptive effects, evaluating and predicting them is key for the development of space systems. The influence of geomagnetic activity on EPBs remains unclear, partly due to limited low‐latitude neutral ...

Modeling the Depletion and Recovery of the Outer Radiation Belt During a Geomagnetic Storm: Combined MHD and Test Particle Simulations

Journal of Geophysical Research: Space Physics, 2018
During geomagnetic storms the intensities of the outer radiation belt electron population can exhibit dramatic variability. Deep depletions in intensity during the main phase are followed by increases during the recovery phase, often to levels that ...

Role of Large‐Scale Traveling Ionospheric Disturbances in the Positive Storm Phase Observed by the Millstone Hill Radar and GNSS TEC Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract A moderate geomagnetic storm was driven by high‐speed solar wind stream on 14 March 2016. We show that large‐scale traveling ionospheric disturbances (LSTIDs) played a significant role in producing the ionospheric storm positive phase at mid‐latitudes in the North American sector.
