Abstract in English
The International Geomagnetic Reference Field (IGRF) is the best
mathematical fit of the observed geomagnetic field at any specific time. It is
adopted by the International Association of Geomagnetism and Aeronomy
(IAGA). Due to the importance of this field for navigation, magnetic survey,
geological mapping and military usage the IAGA evaluates this field every five
years.
