Magnetic Field Variability

Magnetic Field Variability is a geophysical phenomenon characterized by temporal changes in the Earth's magnetic field vector components, distinguished by its origin in both external (e.g., solar-driven ionospheric and magnetospheric currents) and internal (e.g., core dynamo and crustal) sources, as systematically measured and analyzed within the operational framework of geomagnetic observatories.
