OI 630 nm Airglow Observed From Space as a Diagnostic of Nighttime Low‐Latitude Ionospheric Dynamics

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study investigates the nighttime morphology of the bottomside F region (∼250 km) at low latitudes using 630 nm airglow measurements from the Visible and Infrared Spectral Imager (VISI) aboard the Ionosphere, Mesosphere, Upper Atmosphere, and Plasmasphere (IMAP) mission on the International Space Station. For this purpose, we analyzed IMAP/

Neural network prediction of geomagnetic activity: a method using local Hölder exponents [PDF]

, 2002
Local scaling and singularity properties of solar wind and geomagnetic time series were analysed using Hölder exponents . It was shown that in analysed cases due to the multifractality of fluctuations, α changes from point to point.

Study of the Gyro and Divergence Characteristics of Relativistic Charged Particle Beam Propagation in Earth’s Magnetic Field

Advances in High Energy Physics
Relativistic charged particle beam can be used as a destructive beam weapon in space for debris removal tasks. The trajectories of charged particles are affected by both electric and magnetic forces in the Earth’s magnetic field.

Nighttime Westward Equatorial Electrojet Observed During the January 2026 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract The equatorial electrojet (EEJ) is a narrow band of zonal electric current flowing in the E‐region ionosphere within approximately ±2° $\pm 2{}^{\circ}$ latitude of the magnetic equator. At night, the EEJ is generally considered very weak because of low ionospheric conductivity.

Ionospheric F-region currents estimated from Macau Science Satellite-1 and Swarm satellite magnetic data

Earth and Planetary Physics
Accurate modeling of Earth’s ionospheric F-region currents is essential for refining geomagnetic field models and understanding magnetosphere-ionosphere coupling.

Drift Echoes at Geostationary Orbit: An Eight‐Year Climatology From GOES‐16

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Drift echoes are energy‐dispersed recurrences in energetic particle flux that appear when a localized injection or compression organizes trapped ions and electrons according to their azimuthal drift. Although established as tracers of radiation‐belt dynamics, drift echoes have rarely been surveyed statistically at geostationary orbit. We apply

A Global Lithospheric Magnetic Field Model Derived From Multi‐Satellite Gradient Observations and Regional Aeromagnetic Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Using gradient data from the Macau Science Satellite‐1 (MSS‐1), CHAMP, Swarm‐A, and Swarm‐C satellites, together with aeromagnetic model data from China, we built the China‐specific Global Gradient Lithospheric Magnetic Model (CGGLM). The new model reaches spherical harmonic degree 140 and uses the Iteratively Re‐weighted Least‐Squares method ...

Tectonic Evolution of the Mariana Trough

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The Mariana Trough is an active back‐arc basin formed by subduction of the Pacific Plate beneath the Philippine Sea Plate and provides an ideal setting for investigating the evolution of back‐arc basins. In this study, we compile bathymetric, magnetic, and gravity data to reconstruct the formation history of the entire basin.

Episodic Change, Quiescence, and Recovery of Earth's Inner Core Surface

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract While a consensus has emerged that the hypothesis of inner core differential rotation cannot provide a consistent explanation for the seismic data, it remains debated whether the seismic data indicate a concurrence of a temporal change of inner core surface with an inner core differential rotation or the temporal change of inner core surface ...
