Model magnetne deklinacije za Slovenijo ; The model of magnetic declination of Slovenia

Predstavljen je polinomski model magnetne deklinacije za obmo je Slovenije, ki zaradi svojega lokalnega zna aja omogo a to nej e izra unavanje deklinacije, kot je to mogo e s svetovnimi modeli. Podlaga za izra un koeficientov modela so vrednosti magnetne deklinacije na 11 geomagnetnih to kah znotraj obmo ja Slovenije, izmerjene med septembrom 2008 in septembrom 2009, in vrednosti magnetne deklinacije na osmih Sloveniji najbli jih geomagnetnih observatorijih. Rezultati so bili reducirani na epoho 2009,0 in uporabljeni za izra un koeficientov kvadratnega polinomskega modela deklinacij za Slovenijo po metodi najmanj ih kvadratov. Polinomski model je bil primerjan s svetovnim magnetnim modelom WMM. Ugotovljeno je, da so razlike med modeloma precej nje ; 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.
