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.

Automated Detection of Equatorial Plasma Bubbles From the Magnetic Measurements of Macau Science Satellite‐1 Using Machine Learning

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Equatorial plasma bubbles (EPBs) are plasma density depletion structures that produce magnetic field perturbations through the diamagnetic effect and therefore need to be identified and excluded in high‐precision geomagnetic field modeling. Traditional EPB detection methods typically rely on in situ electron density or total electron content ...

Global Energy Circulation During a Solar Wind Density Pulse

Space Weather, Volume 24, Issue 4, April 2026.
Abstract We study the propagation and impacts of a strong density pulse through the magnetosphere during 11:40–12:00 UT near the peak of a geomagnetic storm on 3 February 2022. Using the Space Weather Modeling Framework Geospace global simulation, we show how the energy transport in the magnetosphere is enhanced promptly after the pulse arrival at the ...

Post‐Processing Probabilistic Forecasts of the Solar Wind by Data Mining Similar Scenarios

Space Weather, Volume 24, Issue 4, April 2026.
Abstract The solar wind speed at Earth is one of the most important parameters regarding the effects of space weather on society. Thus far, most approaches for predicting the solar wind speed produce a single‐value time series without uncertainty, or utilize ensemble methods which require custom calibration development.
