Abstract

The results of testing the reliability of the linear forward extrapolation up to five years by using of historical data series of Tihany (THY), L'Aquila (AQU), Fürstenfeldbruck (FUR), Grocka (GCK) and Panagyurishte (PAG) geomagnetic observatories, as well as of Croatian geomagnetic secular network point Pokupsko (POKU), were shown. Using residuals (difference of predicted and actual declination value), the accuracy of the prediction for simulated cases with survey periods of one, two and four years was estimated.

Keywords

geomagnetic declination; linear prediction
