Global MHD Simulations: Magnetosphere–Ionosphere Coupling Dependence on Conductance Model

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Eighty‐five geomagnetic storms were simulated with the space weather modeling framework Geospace model using two different ionospheric conductance models. One set used the legacy conductances within the Ridley ionosphere model, while the other set used the newly developed conductance model for extreme events conductance model.

Recurrence based quantification of dynamical complexity in the Earth's magnetosphere at geospace storm timescales

, 2018
Magnetic storms are the most prominent global manifestations of out-of-equilibrium magnetospheric dynamics. Investigating the dynamical complexity exhibited by geomagnetic observables can provide valuable insights into relevant physical processes as well

Evaluating Multipoint Sampling of Global‐Scale High‐Latitude Electrodynamics by the Geospace Dynamics Constellation

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract The Geospace Dynamics Constellation (GDC) mission aims to investigate the dynamic coupling between the magnetosphere, ionosphere, and thermosphere by resolving key spatiotemporal processes at scales ranging from local to global. A key aspect is GDC's ability to reconstruct hemispheric‐scale high‐latitude electrodynamics with comprehensive ...

ASSESSMENT OF THE SEVERE GEOMAGNETIC STORM ON MAY 10-11, 2024 EFFECTS ON THE GEOMAGNETIC FIELD AND IONOSPHERE OVER THE INDONESIAN REGION

Rudarsko-geološko-naftni Zbornik
The severe geomagnetic storm on May 11, 2024, is the largest space weather phenomenon in the 25th solar cycle. This paper presents the impact of that severe geomagnetic storm (Dst = -412 nT) on the geomagnetic field and ionosphere over Indonesia ...

Prediction Space Weather Using an Asymmetric Cone Model for Halo CMEs

, 2007
Halo coronal mass ejections (HCMEs) are responsible of the most severe geomagnetic storms. A prediction of their geoeffectiveness and travel time to Earth's vicinity is crucial to forecast space weather.
