Italian Magnetic Network and Geomagnetic Field Maps of Italy at year 2000.0

Abstract

Since the 1930’s a modern Italian Magnetic Network composed of repeat stations regularly distributed over the Italian territory and integrated by Magnetic Observatories, has allowed the determination of the spatial structure and the time variation of the Earth’s magnetic field over Italy. In this paper the results of the latest Italian magnetic survey undertaken over 114 stations, uniformely distributed over the Italian peninsula and islands, are presented. Data reduced at the year 2000.0 have been used to compute normal fields and to update a second order network of 2550 stations, to draw new magnetic maps for all geomagnetic field elements (D, H, Z and the total field F) for Italy at the year 2000.0.
