The paleofield orientations are consistent with known paleo-orientation during the formation of the crater at approximately 1.0 Ma and differ clearly from the IGRF at this site with a declination of 12[degrees]N).
El IGRF es muy util para todo tipo de aplicaciones donde un campo promedio (regional) es necesario, pero para aplicaciones cientificas que requieren la mayor precision posible o que incluyen descripciones de algunas contribuciones externas o litosfericas, se construyen otros modelos.
Ryskin found strong temporal and spatial correlation between his calculated secular variation and the IGRF figures between 1995 and 2000.
The real inclination of the magnetic field at ground level as opposed to that predicted by world models based on higher altitude data (International Geomagnetic Reference Field (IGRF) models) was obtained using a Magnaprobe gimbaled magnetic needle.
The observed value for the inclination of the magnetic field (+10 degrees to horizontal) differs markedly from the predicted IGRF value of -30 degrees.
After a series of "disconcerting" events, Zurich's mayor at the time, Urs Widmer, agreed to negotiate with the activists and granted them a temporary permit, giving the IGRF total control over the factory.
where [alpha] is the magnetic declination computed from the international geomagnetic reference field (IGRF) or world magnetic model (WMM) using position information.
The geomagnetic gradient was removed using the January 1974 International Geomagnetic Reference Field (IGRF).
Los datos se usan para establecer los modelos globales de referencia, como el Campo Geomagnetico de Referencia Internacional (IGRF).
This relocation process introduces an error, which can be evaluated for the present time through the International Geomagnetic Reference Model (IGRF) and for the last 400 years through the historical GUFM1 model (Jackson et al., 2000).
El campo internacional de referencia IGRF 2000 [International Association of Geomagnetism and Aeronomy (IAGA, 2000)] fue usado para remover de los valores observados el campo magnetico principal, obteniendose asi las anomalias magneticas [DELTA]T.
Los datos de campo fueron corregidos por variacion diurna, la correccion de referencia internacional con el IGRF del 2005, y una eliminacion de picos, teniendo en cuenta la tendencia de la relacion senal-ruido.
