Space Weather, Volume 24, Issue 4, April 2026.Abstract Real‐time Global Ionospheric Map (RT‐GIM) products, provided by the International GNSS Service (IGS), are designed to support time‐sensitive applications by offering ionospheric information with only a few minutes of latency. However, their accuracy falls far short of the high‐precision Final GIM, particularly during periods of intense solar ...

Satellite Reentry Predictions During Sudden Stratospheric Warmings
Space Weather, Volume 24, Issue 4, April 2026.Abstract Prediction of uncontrolled satellite reentry time and trajectory are essential to avoid damages to human being and properties over land. Reentry time and trajectory are largely controlled by aerodynamic drag and mass neutral density below 200 km.

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 ...

A Transferable Real‐Time MUF Forecasting Model for HF Communication in China
Space Weather, Volume 24, Issue 4, April 2026.Abstract High‐frequency (HF) communication is an important means of strategic and emergency communication, playing an irreplaceable role in both military and civil applications. The maximum usable frequency (MUF) is a key parameter controlling HF signal propagation, and its real‐time and accurate forecast has long been a major challenge in engineering.

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.

The Prediction of Short‐Term Atmospheric Density in Lower Thermosphere
Space Weather, Volume 24, Issue 4, April 2026.Abstract Accurate short‐term prediction of atmospheric density in the lower thermosphere (85–125 km) is essential for precise orbit determination and satellite drag mitigation, particularly during geomagnetic storms. Although physics‐based models such as NRLMSIS 2.1 provide empirical estimates, their effectiveness is limited under extreme space weather.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.Abstract Intense and rapidly changing electrical currents in near‐Earth space produce geomagnetic disturbances (GMDs) with large magnetic field rates of change (dB/dt) and in turn large geomagnetically induced currents (GICs) in nearby power lines and pipelines. This study builds on the work of Engebretson, Yang, et al.
