Outer Radiation Belt Dynamics During the October 2012 Storm Revisited: Rapid Inward Radial Transport From a Dynamic Outer Boundary

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Earth's outer radiation belt electron flux is highly variable and can be enhanced by over an order of magnitude over timescales less than one day, as observed during the October 2012 storm. Previous studies of this storm (e.g., Reeves et al., 2013, https://doi.org/10.1126/science.1237743) have invoked local acceleration to explain this ...

Development and Investigation of a Modification to Extend the Dynamic Range of Electrostatic Analyzers

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Plasma populations within the solar system are distributed over a substantial range of densities, kinetic temperatures, and bulk velocities, from the solar wind to Earth's ionosphere. Measuring the full range of plasma conditions for some of these populations is difficult for current top‐hat electrostatic analyzers, let alone for multiple ...

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.

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 ...
