Operational modelling of geomagnetic fields and geomagnetically induced currents

2021
Geomagnetically induced currents (GICs) have long been known to affect power systems adversely. Modelling these GICs usually involves consideration of a chain of coupled systems. The scope of the modelling chain spans multiple disciplines, from solar physics through to geophysics and power engineering.

An Equivalent Source Model for the Geomagnetic Field

2013
A new model for the geomagnetic field is presented. It does not rely heavily on the present-day field, which has some ephemeral characteristics, but mostly on paleomagnetic data from lava flows, in particular the large Icelandic data set. The model consists of an axial dipole and vertical off centered dipoles representing the non-axial-dipole field ...

Models of the geomagnetic field on the territory of the Republic of Macedonia

2008
The aim of this paper is to present various geomagnetic field models of Macedonia based on measurements at repeat stations as well as satellite data covering this region. At first a theoretical basis of the geomagnetic field, spherical cap harmonical model and polynomial model will be given.

Regional geomagnetic field model for Croatia

2015
Geomagnetic components at Croatian repeat stations and ground survey sites, as well as European observatories and repeat stations, were used to obtain a regional geomagnetic model over Croatia at 2009.5 epoch. Different models were derived, depending on input data, and the modelling techniques were Adjusted Spherical Harmonic Analysis and Spherical ...

On The Modeling Of The Regional Geomagnetic Field

2006
Cilj rada bio je regionalno modeliranje glavnog magnetskog polja i njegove sekularne promjene primjenom sferne harmoničke analize na kuglinoj kaloti SCHA, tehnike (Spherical Cap Harmonic Analyses). Europsko područje izabrano je za modeliranje, budući je mreža geomagnetskih opservatorija ovdje najgušća.
