Count Component Title Abstract
1 International Geomagnetic Reference Field - 11th Generation The eleventh generation of the International Geomagnetic Reference Field (IGRF) was adopted in December 2009 by the International Association of Geomagnetism and Aeronomy Working Group V-MOD. It updates the previous IGRF generation with a definitive main field model for epoch 2005.0, a main field model for epoch 2010.0, and a linear predictive secular variation meodel for 2010.0-2015.0.

LE_ProcessStep or LI_ProcessStep

Count Component DateTime Description
1 Seven teams from the IAGA V-MOD group created independent candidate models for the IGRF-11. The models used the same datasets from satellites and land observatories with different criteria, filters, and processing steps. The various candidate models and their descriptions can be found at http://www.ngdc.noaa.gov/IAGA/vmod/candidatemodels.html
1 The seven models were tested, evaluated, and compared by C.C. Finlay et al. The final model was calculated using weighted means of the candidates. The weights were agreed by a vote of the IGRF-11 task force.
