International Geomagnetic Reference Field (IGRF)
Entry ID: IAGA_IGRF
[ Update this Record ]


Summary
Abstract: The International Geomagnetic Reference Field (IGRF) is a mathematical description of the Earth's main magnetic field used widely in studies of the Earth's deep interior, the crust and the ionosphere and magnetosphere. Production of the IGRF is an international collaborative effort relying on co-operation between magnetic field modellers and institutes and agencies responsible for collecting and publishing geomagnetic field data. The IGRF incorporates data from permanent observatories and from land, airborne, marine and satellite surveys. The latest version of the model - the 9th Generation IGRF - was finalised by Working Group 8 of IAGA Division V in July 2003 at the IUGG XXIII General Assembly in Sapporo, Japan. It includes models of the main field at five-year intervals from 1900 to 2000, and a secular variation model for 2000-2005.
