Comparative Dynamics of Substorms and Sawtooth Events

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present a comprehensive comparative analysis of magnetospheric substorms and sawtooth events using multi‐point observations from ground‐based magnetometers, geostationary satellites, and the Time History of Events and Macroscale Interactions during Substorms mission.

A New Strategy for Improving Multi‐Frequency PPP‐RTK Ionospheric Correction Availability and User Performance in Low‐ and Middle‐Latitudes

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract High‐precision regional ionospheric correction products are essential for achieving accurate and fast‐convergence solutions in Precise Point Positioning Real‐Time Kinematic (PPP‐RTK). For users in low‐ and middle‐latitudes, PPP‐RTK server narrow‐lane (NL) ambiguity resolution (AR) typically requires more than 10 min, which largely affects the ...

A Unified Vector Electromagnetic Framework for Ionospheric Scintillation and Polarization Effects in GNSS

Radio Science, Volume 61, Issue 6, June 2026.
Abstract The ionosphere imposes coupled amplitude, phase, and polarization distortions on trans‐ionospheric Global Navigation Satellite System (GNSS) signals, reflecting the structure and dynamics of electron‐density irregularities. Classical weak‐scatter theory provides a mature framework for interpreting amplitude and phase scintillation, but these ...

Importance of High Cadence Magnetometer Data for Investigating Geomagnetic Disturbances

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Geomagnetic disturbances (GMDs) are rapid changes in the magnetic field of the Earth that may drive geomagnetically induced currents (GICs), known to cause damage to infrastructure such as power grids and pipelines. Globally, GIC measurements are often hard to obtain; therefore, GMDs are used as a proxy for GICs.

Geomagnetically Induced Currents, Transformer Harmonics, and Reactive Power Impacts: Observed Response of a Single‐Phase Transformer in New Zealand

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Geomagnetic storms represent a space weather hazard to power transmission networks due to the effects of induced geo‐electric fields within the conducting surface of the Earth. These drive electric currents in power transmission lines which can flow to ground through the neutral‐ground connections of transformers.

A Machine‐Learning‐Based Global Thermospheric Density Forecasting Model

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Thermospheric mass density governs aerodynamic drag in low Earth orbit and is a primary source of uncertainty in orbit prediction and conjunction assessment, particularly during geomagnetic disturbances. We present AETHER‐P3 ${\mathrm{P}}^{3}$ (Accelerometer‐driven Estimation of THERmospheric density–A Physics‐Informed Probabilistic Prediction
