Ionosphere‐Thermosphere Coupling in the Northern Polar Region During the May 2024 Geomagnetic Superstorm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract The May 2024 superstorm, as the most intense geomagnetic storm since 2003, caused a variety of disturbances in the magnetosphere‐ionosphere‐thermosphere system. This study investigates the long‐lasting electron density depletion in the polar region and the underlying ionosphere‐thermosphere coupling, based on a comprehensive set of ...

Signal Processing for the Cluster Wideband Data Burst Mode

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract The Wideband Data instrument is part of the Cluster spacecraft Wave Experiment Consortium. Its primary data path is a direct connection to the spacecraft data handling system providing real time downlink to the ground stations of the Deep Space Network and Panska Ves Observatory.

Global Morphology of Chorus Waves in the Outer Radiation Belt and the Effect of Geomagnetic Activity and fpe ${f}_{pe}$/fce ${f}_{ce}$

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Whistler‐mode chorus waves play a key role in driving radiation belt dynamics by enabling both acceleration of electrons to relativistic energies as well as their loss into the atmosphere via pitch‐angle scattering. The ratio between the electron plasma frequency (fpe ${f}_{pe}$) and the electron gyrofrequency (fce ${f}_{ce}$) significantly ...

Differentiating Plumes and Local Torus Segments of Enceladus

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Enceladus's south polar plumes and their surrounding torus segments (local plasma regions formed by plume material diffusion) are key to understanding its magnetospheric interaction; however, clear observational criteria to distinguish them remain lacking.
