| description | The models of the distribution of the elements of the geomagnetic field must
be updated regularly. For this purpose geomagnetic measurements have to be carried out
repeatedly at geomagnetic observatories as well as at temporary observation points. In
this paper the results of the geomagnetic survey that was carried out in Slovakia in the year
2014 are presented. The measurements were performed at 12 observation points and they
were reduced to the 2014.5 epoch. The secular variation between 2007.5 and 2014.5 was
also calculated. The obtained values of the geomagnetic elements were used for calculating
a 1st-degree polynomial model for the distribution of magnetic declination, inclination
and total field. The comparison with the IGRF model showed that the polynomial model
provided more accurate results for magnetic inclination and total field. For magnetic
declination, on the contrary, the IGRF model produced slightly better results than the
polynomial model. |
