Toward GIC Forecasting: Statistical Downscaling of the Geomagnetic Field to Improve Geoelectric Field Forecasts [PDF]
Space Weather, 2022 AbstractGeomagnetically induced currents (GICs) are an impact of space weather that can occur during periods of enhanced geomagnetic activity. GICs can enter into electrical power grids through earthed conductors, potentially causing network collapse through voltage instability or damaging transformers.

Geoelectric monitoring at the Boulder magnetic observatory [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2017 Despite its importance to a range of applied and fundamental studies, and obvious parallels to a robust network of magnetic-field observatories, long-term geoelectric field monitoring is rarely performed.

Factor analysis of multi−electrode geoelectric field data
Multidiszciplináris tudományok, 2022 The paper presents the results of the factor analysis of multi-electrode geoelectric data measured in the area of the Surány aquifer. The 9-variable dataset measured on the first profile was examined by factor analysis using 2, 3, 4 and 5 factors. The calculations show that the Factor profile 1 carries the effects of IP (Induced Polarization), while ...
