Abstract: Objective The relationship between the observed value and the latest World Magnetic ModelWMM2010,constructed with various satellite geomagnetic data,is studied;as well as the relationshipbetween the observed value and the International Geomagnetic Reference Field model IGRF11.First-928 ly,a comparison is made between IGRF11and the observed value.The precision and reliability of IG-RF was evaluated.Then,the difference between WMM2010and IGRF11 was analyzed.Indexes,such as absolute errors,mean square root errors,relative errors and weigh coefficients,are introducedto compare the two models.The results suggest that the WMM2010model has more reference valuefor the normal field correction in the geomagnetic abnormity field research,thus filling agap to im-prove the boundary effect.
