Geomagnetic field survey activities in Lithuania

Abstract

Europe is the region with the densest network of geomagnetic observatories and repeat stations. Lithuania, supported by Polish specialists, has successfully integrated in the European geomagnetic field research activities. Six repeat stations were established in 1999 and precise geomagnetic field measurements were performed in 1999, 2001, 2004 and 2007 there. Additional measurements in four airports of Lithuania were done in 2006, 2007 and 2010. Based on measured data the analysis of geomagnetic field parameter changes was performed. Accumulated data was processed and used for updating Lithuanian declination map and magnetic declination model accuracy estimating. Updated data could be used in the fields of cartography, navigation, geology, geophysics.
