Statistical Scale Analyses of a Diurnal Periodicity in Auroral Kilometric Radiation, Observed by Wind/WAVES

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The Earth's strongest natural radio emission is Auroral Kilometric Radiation (AKR), which is correlated with auroral intensity, and is a barometer for space weather. AKR is generated by the electron cyclotron maser instability, with sources on auroral field lines. Previous work on AKR and radio emissions from other planets (or stars) points to

Analysis of Seismo-Ionospheric Anomaly Disturbance Associated with the Mw7.6 Mexico Earthquake on 19 September 2022

Atmosphere
GNSS ionospheric records are valuable measurements of earthquake-related ionospheric anomalies. The deep exploration of GNSS ionospheric data can help to better understand the seismic–ionospheric coupling effect.

Can Solar Cyclic Variability Mimic Extreme Solar Particle (Miyake) Events in Radiocarbon?

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Rapid, strong enhancements in Δ14 ${{\Delta }}^{14}$C in the Earth's atmosphere, known as Miyake events, rarely occurred over the past millennia, pointing to major radiation storms affecting Earth. They are produced by extreme solar particle events (ESPEs) and are separated by an order‐of‐magnitude gap in the strength from directly observed ...

Impacts of Neutral Wind‐Driven Currents on Geomagnetic Disturbances and Magnetospheric Dynamics During the May 2024 Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The neutral wind dynamo generates ionospheric currents that can significantly affect high‐latitude electrodynamics during geomagnetic storms, yet its role in global magnetosphere‐ionosphere coupling is often underrepresented. We quantify the impact of wind‐driven currents on geomagnetic disturbances (GMDs) and magnetospheric dynamics during ...

Modeling Kinetic Reconnection Onset in Global Magnetospheric Simulations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract We investigate the onset of magnetic reconnection in Earth's magnetotail using a coupled magnetohydrodynamic with embedded particle‐in‐cell (MHD‐EPIC) model, which self‐consistently links global magnetospheric dynamics to electron‐scale kinetic processes. Unlike standalone kinetic simulations with idealized boundary conditions, reconnection in

Distinct Groundwater Regimes in West Antarctic Sedimentary Basins Inferred From Magnetotelluric Imaging

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Subglacial sedimentary basins in Antarctica are hypothesized to modulate ice flow and biogeochemical cycles via groundwater and geothermal feedbacks, yet their properties remain poorly constrained. Here, we present a joint quantitative analysis of new magnetotelluric (MT) data acquired at Thwaites Glacier (TG) and WAIS Divide, alongside legacy

Thermal and Structural Signatures Associated With Subducted Seamounts in Hyuga‐nada and Off Cape Muroto, Southwest Japan

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We present heat flow estimates beneath the forearc slopes off Hyuga‐nada and Cape Muroto in the Nankai Trough, where the Philippine Sea plate subducts beneath the southwestern Japan. Using seismic reflection data, we identified Bottom Simulating Reflectors and derived heat flow ranging from 20 to >140 mW/m2.

Magnetic Dual‐Layer Equivalent Sources on the Sphere

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The equivalent source method is widely used for processing and interpolating magnetic data, particularly in airborne surveys. However, implementations based on Cartesian coordinates present limitations at regional and global scales, where Earth curvature introduces geometric inconsistencies that affect data integration and modeling accuracy ...
