Katz Fractal Dimension of Geoelectric Field during Severe Geomagnetic Storms
Entropy, 2021 We are concerned with the time series resulting from the computed local horizontal geoelectric field, obtained with the aid of a 1-D layered Earth model based on local geomagnetic field measurements, for the full solar magnetic cycle of 1996–2019 ...

Mapping Geoelectric Field Hazards in Ireland
Space WeatherGeoelectric fields are generated at the Earth's surface and can lead to the induction of hazardous geomagnetically induced currents (GIC) in infrastructure like power grids, railways and pipelines during geomagnetic storms.
