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.
Reports/Work-in-Progress at the 2007 ESWW GETG Web Activities Home Site update (Magnus Wik, Sweden) – next slide Created/edited Wikipedia articles on Space Weather and GIC – next slide GETG and Engineering Conferences/Journals Risto Pirjola – EUROEM 2008 + discussion on outreach to industry Space situational awareness, GETG and the SWWT Led by Mike Hapgood (Chair SWWT) + discussion on FP7 opportunities Reports on new research work and publications (2006-2007) Alan Thomson (UK) – New PhD study for UK grid risk, South Africa GIC workshop planned Larisa Trichtchenko (Canada) – Outreach activities at North America, including industry conferences Pavel Hejda (CZ) – Study of pipeline GIC in Czech Republic gas network Jurgen Watermann (DMI) – DMI concentrating now on data collection and remote sensing, not space physics Risto Pirjola (FMI) – Active GIC collaborations e.g. with Brazil, Sweden, …
