Sažetak
Geomagnetic components at Croatian repeat stations and ground survey sites, as well as European observatories and repeat stations, were used to obtain a regional geomagnetic model over Croatia at 2009.5 epoch. Different models were derived, depending on input data, and the modelling techniques were Adjusted Spherical Harmonic Analysis and Spherical Harmonic Analysis. It was derived that the most accurate model over Croatia was the one when only Croatian data were used, and by using the Adjusted Spherical Harmonic Analysis. The models were obtained by taking into account the empirical adjustment for long-term external field variations.
