Analysis of factors affecting the disturbance of geoelectric field observation at Wengtian station
地震科学进展, 2022 The quality of the geoelectric field data of Wenchang Wengtian station in Hainan Province has been declining since March 2019. The quality of the geoelectric field data has declined mainly due to the low daily correlation coefficient, the reverse change ...

An investigation of the basement complex aquifer system in Lofa county, Liberia, for the purpose of siting boreholes [PDF]
, 2014 Liberia is recovering from a 14 year civil war and only 51% of the rural population has access to safe drinking water. Little hydrogeological knowledge survives in Liberia, increasing the difficulty in successfully siting new boreholes.

Estimating Geomagnetically Induced Currents in Southern Brazil Using 3‐D Earth Resistivity Model
Space Weather, 2023 Geomagnetically induced currents (GICs) result from the interaction of the time variation of ground magnetic field during a geomagnetic disturbance with the Earth's deep electrical resistivity structure.

Regression‐based forecast model of induced geoelectric field
Space Weather, 2017 AbstractThe electric field induced due to solar activity is the driver of geomagnetically induced currents (GIC) in grounded conductor networks such as power grids. We present a regression‐based (i.e., empirical) model for quantitatively predicting the upper envelope of induced E field components, using near‐Earth measurements of solar wind plasma and ...

Geoelectric Field Evaluation During the September 2017 Geomagnetic Storm: MA.I.GIC. Model [PDF]
Space Weather, 2019 AbstractThe space environment near Earth is constantly subjected to changes in the solar wind flow generated at the Sun. Examples of this variability are the occurrence of powerful solar disturbances, such as coronal mass ejections (CMEs). The impact of CMEs on the Earth's magnetosphere perturbs the geomagnetic field causing the occurrence of ...

Forecasting GICs and Geoelectric Fields From Solar Wind Data Using LSTMs: Application in Austria
Space Weather, 2022 The forecasting of local GIC effects has largely relied on the forecasting of dB/dt as a proxy and, to date, little attention has been paid to directly forecasting the geoelectric field or GICs themselves.

Modelling the effects of space weather at the Earth’s surface : a UK geoelectric field model [PDF]
, 2004 Geomagnetically Induced Currents (GIC), which can flow in technological systems such as power transmission grids, are a consequence of the geoelectric field induced at the surface of the Earth during geomagnetic storms.
