Multi‐Decadal Trends in the Low Latitude foF2 Driven by Secular Magnetic Variations
Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract Long‐term ionospheric trends have been widely studied, but their origin and magnitude remain subjects of debate. This study quantifies the linear trend in the F2‐region critical frequency (foF2) and its local time dependence using observations from eight low‐latitude ionosonde stations.

Validation of VERB‐3D Simulation Results in Response to the COSPAR ISWAT Challenge
Space Weather, Volume 24, Issue 5, May 2026.Abstract In response to the first long‐term simulation challenge issued by the COSPAR International Space Weather Action Team (ISWAT) G3‐04 team (“Internal Charging Effects and the Relevant Space Environment”), we evaluate the performance of the Versatile Electron Radiation Belt‐3D model by simulating the radiation belt electron dynamics for the entire

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract At frequently erupting volcanoes, magma and volatiles ascend through established pathways, but the complete picture of their branching and supply system remains unclear. We integrated self‐potential (SP), broadband magnetotelluric (MT), and helium isotope observations to image magma and volatile pathways beneath Sakurajima Volcano.

On the causes of geomagnetic activity [PDF]
The causes of geomagnetic activity are studied both theoretically in terms of the reconnection model and empirically using the am-index and interplanetary solar wind parameters. It is found that two separate mechanisms supply energy to the magnetosphere.
