Applying inversion techniques to derive source currents and geoelectric fields for geomagnetically induced current calculations

This research focuses on the inversion of geomagnetic variation field measurement to obtain source currents in the ionosphere. During a geomagnetic disturbance, the ionospheric currents create magnetic field variations that induce geoelectric fields, which drive geomagnetically induced currents (...
