Geomagnetic Storm Effects on the LEO Proton Flux During Solar Energetic Particle Events
Space Weather, 2023 During a few solar energetic particle (SEP) events, solar protons were trapped within the geomagnetic field and reached the outer edge of the inner radiation belt.

Modelling the geomagnetic field.
Journal of geomagnetism and geoelectricity, 1990 Spherical harmonic models of the main geomagnetic field and its secular variation are used by navigators, exploration geophysicists, drillers of oil wells and by scientists studying the Earth's interior, its ionosphere and magnetosphere. The data on which such models are based must be of the highest quality and must be distributed as homogeneously as ...

Influence of different data selection criteria on internal geomagnetic field modeling
Earth and Planetary PhysicsEarth’s internal core and crustal magnetic fields, as measured by geomagnetic satellites like MSS-1 (Macau Science Satellite-1) and Swarm, are vital for understanding core dynamics and tectonic evolution.

A multisource geomagnetic field model incorporating ocean circulation-induced magnetic field
Earth and Planetary PhysicsThe movement of global ocean circulation in the Earth’s main magnetic field generates a measurable induced magnetic field (about 2 nT at geomagnetic satellite altitudes).

On the Regional Variability of dB/dt and Its Significance to GIC
Space Weather, 2020 Faraday's law of induction is responsible for setting up a geoelectric field due to the variations in the geomagnetic field caused by ionospheric currents. This drives geomagnetically induced currents (GICs) which flow in large ground‐based technological

Correlation‐based modeling and separation of geomagnetic field components [PDF]
Journal of Geophysical Research: Solid Earth, 2016 AbstractWe introduce a technique for the modeling and separation of geomagnetic field components that is based on an analysis of their correlation structures alone. The inversion is based on a Bayesian formulation, which allows the computation of uncertainties.
