Results of the Modelling of the Geomagnetic Field for a Small Territory

Analysis of the different methods of geomagnetic field modelling on the territory of Slovakia is made. Data on the territory of Slovakia was reduced for epoch 1980.5 and compared with values from three models: linear model, IGRF 1980, IGRF, revision 1985. Study of distribution of the deviations from IGRF's for individual points have led to the conclusion there exists a systematic pattern. One of the possible explanations could be a regional anomaly of the geomagnetic field in Europe.
