Abstract: | In the frame of a long-time collaboration between INGV (Istituto Nazionale di Geofisica e Vulcanologia) and IGMI (Istituto Geografico Militare Italiano), also in the years 2009 and 2010 a survey of 131 repeat stations of the Italian Magnetic Network (including 2 observatories, 11 stations in Albania and 3 in Corsica and 1 in Malta) was carried out. In this paper the procedures for magnetic measurements and data elaboration are described. Furthermore, for all the repeat stations data reduced at of the measurement day, at the epoch 2010.0; are presented. At the same epoch the coefficients for normal fields were determined for all the data, in order to draw the new maps of the geomagnetic field elements (D, H, Z and total field F) at the year 2010.0, at 1: 2 000 000 scale. All these maps were created by mean of interpolation procedures on GIS platform. |
