Comparison of regional field models compiled by different methods for the area of Croatia and Hungary

Different adjustment methods have been applied to model the core magnetic field over Croatia and Hungary.The methods have been tested on EMM data. PA, CPA, and ASHA methods resulted in similar mean residuals for the fitted models.Because of its physical justification it is suggested that the obtained ASHA model is superior over the polynomial models. The mean residual of the order of 20-30 nT obtained for the case of the adjustments represents the anomalous part of the stations of the joint Croatian-Hungarian network.
