Geomagnetic Data in Iceland

Geomagnetic data obtained by a fluxgate magnetometer at three observatories in Iceland, Tjornes, Husafell, and Aedey, during the period from September 2001 to January 2004. These observatories are maintained by National Institute of Polar Research, Japan in collaboration with Science Institute, University of Iceland.

[Geographic and Magnetic Coordinates]
* Geomagnetic coordinates are calculated by the IGRF model at 00 UT on 23 November 2003 at altitude of 100 km above observatory.
