Abstract:

A polynomial model of magnetic declination for the area of Slovenia is presented. The model enables calculations of magnetic declination that are, due to its local characteristics, more accurate than the results of the global models. The basis for the estimation of polynomial coefficients are the magnetic declination values of 11 geomagnetic points in Slovenia, obtained between September 2008 and September 2009, and the magnetic declination values of eight geomagnetic observatories in the vicinity of Slovenia. The results were reduced to the epoch 2009,0 and used with the least square method to obtain the coefficients of the second order polynomial model. The model was compared to the World Magnetic Model (WMM). The estimated differences are considerable.
