The State of Solar Wind Heavy Ions in Interplanetary Coronal Mass Ejection–Driven Geomagnetic Storms

The Astrophysical Journal
During geomagnetic storms, which are the primary periods for heavy ions from the solar wind to enter Earth’s magnetospheric space, the charge state of solar wind heavy ions during these storms has significant implications for studying the distribution ...

Unraveling Super Equatorial Plasma Bubbles (EPBs) Evolution During the 23 April 2023 Storm: Multi‐Instrument Observations and GITM‐SAMI3 Simulation

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Storm‐time equatorial plasma bubble (EPB) dynamics play a critical role in space weather impacts on communication and navigation systems, yet the mechanisms governing their formation and evolution under storm conditions remain poorly understood.

The Characteristics and Possible Mechanisms of the Strongest Ionospheric Irregularities in March 2024

Atmosphere
A geomagnetic storm occurred on 3 March 2024, with the minimum SYM-H reaching −127 nT. Although this geomagnetic storm was not very strong, the ionospheric irregularities on this day resulted in a strong ionospheric scintillation.

RT‐FAIRS: Real‐Time Factor‐Adjusted Ionospheric Residual Statistics Approach for Generating Accuracy Information in Global Ionospheric Maps

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Ionospheric delays remain a major error source in Global Navigation Satellite Systems (GNSS). The International GNSS Service (IGS) provides Global Ionospheric Maps (GIMs) that offer vertical total electron content (VTEC) estimates together with RMS maps as accuracy information.

Comprehensive and Open Assessment of Thermospheric Models During Geomagnetic Storm Times Within CCMC Framework

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Thermospheric neutral density controls satellite drag in low Earth orbit and varies strongly during geomagnetic storms. We present a multi‐mission, phase‐resolved assessment of empirical and physics‐based thermosphere models using 151 storms from 2001 to 2023, including MSIS, DTM, JB2008, WAM‐IPE, WACCM‐X, GITM, CTIPe, and TIE‐GCM.

The Pointing Error Due To Laser Propagation in Space Plasma for TianQin Gravitational Wave Detection

Space Weather, Volume 24, Issue 4, April 2026.
Abstract TianQin, a space‐borne gravitational wave observatory, is designed to detect gravitational‐wave signals via laser interferometry. As the inhomogeneous space plasma surrounds the inter‐satellite laser links, the propagation of the laser in space plasma can introduce pointing error noise.
