Localized Threats: How Ground Conductivity Shapes the Geoelectric Response

Space Weather
Geomagnetic storms can induce strong geoelectric fields in the ground. These fields drive geomagnetically induced currents in technological conductor systems, such as power grids.

A Dual-Prediction Framework for High-Energy Proton Flux Driven by Graph Neural Networks

IEEE Access
Predicting high-energy proton flux is essential for radiation-effect protection of satellite devices. We introduce a dual-prediction framework based on Graph Neural Networks (GNN) to model proton flux from both non-time-series and time-series ...

Mathematical Model of the Geomagnetic Field

, 2006
First comes a description of a mathematical model of the geomagnetic field. Then some discussion of the classical non-uniqueness results of Backus. Further we look at more recent results concerning reconstruction of the geomagnetic field from intensity and the normal component of the field. New stability estimate for this reconstruction is obtained.
