A comparison of methods for estimating the geoelectric field [PDF]
Space Weather, 2017 AbstractThe geoelectric field is the primary input used for estimation of geomagnetically induced currents (GICs) in conducting systems. We compare three methods for estimating the geoelectric field given the measured geomagnetic field at four locations in the U.S.

Space Weather, Volume 24, Issue 1, January 2026.Abstract Geomagnetically induced currents (GICs) are telluric currents driven by space weather that can adversely impact high voltage transformers in electricity supply networks. It is often difficult to obtain transformer GIC data so ground based magnetometer data may be used to estimate the transformer GIC via complex modeling of both network and ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.Abstract Deep learning (DL) is an increasingly popular method for inverting the transient electromagnetic (TEM) data. Currently, DL‐based inversion for TEM data primarily employs supervised learning methods that rely on labeled data sets to train the network.

Evaluating the applicability of the finite element method for modelling of geoelectric fields [PDF]
Annales Geophysicae, 2013 Geomagnetically induced currents in power systems are due to space weather events which create geomagnetic disturbances accompanied by electric fields at the surface of the Earth.

Seismic reflection and topography insights into Ries crater diameter and megablock zone
Meteoritics &Planetary Science, Volume 60, Issue 12, Page 2891-2912, December 2025.Abstract Most of the extensive crater‐wide geophysical studies at the Ries impact structure were made decades ago when the origin of the structure was still being debated. Although it is one of the most studied impact structures, its internal structure was not imaged in high resolution until recently.

Relationship between Interplanetary Conditions and Changes in the Geomagnetic Field to Understand the Causes of Geomagnetically Induced Currents [PDF]
, 2018 Geomagnetically Induced Currents (GICs) are electrical currents induced in ground-level conductive networks, like power lines and pipelines, which can cause costly damage to infrastructure.

Modeling Geoelectric Fields in Ireland and the UK for Space Weather Applications [PDF]
Space Weather, 2019 AbstractGeoelectric fields at the Earth's surface caused by geomagnetic storms have the potential to disrupt and damage ground‐based infrastructure such as electrical power distribution networks, pipelines, and railways. Here we model geoelectric fields in Ireland and the UK during both quiet and active time intervals of geomagnetic conditions using ...
