1. Ground Effects Topical Group Includes (but is not limited to) activities such as Modelling the occurrence of geomagnetic variations and geoelectric fields during space weather events Modelling GIC in electric power systems (discrete earthings) Modelling GIC in buried pipeline networks (continuous earthing) Measurements of geomagnetic variations, geoelectric fields and GIC Development of forecast techniques of GIC based on neural networks or on physical models Collaboration with power and pipeline industry on GIC research Advice on and forecast of geomagnetic activity to users, such as oil drilling and prospecting industry and aeromagnetic survey enterprises Stated aim is to expand group activities to encourage wider scientific collaborations E.g., post-ESWW, the group has discussed (by email) jointly exploiting world archives of magnetic data, for example to look again at the Carrington event of 1859.
