La RETE MAGNETICA ITALIANA e la variazione secolare dal 1935 in poi

In 1985.0 the Istituto Nazionale di Geofisica and Istituto Geografico Militare Italiano have completed the repetition of the 1st order Italian geomagnetic network. The secular variation in Italy computed starting from the 1st order data of the 1935.0 network, will be shown for groups of years. This study was made starting from 1935.0 network comparing it with the 1965 (made during the Word Magnetic Survey), with the Progetto Finalizzato Geodinamica 1979.0 network, and with the last ING-IGMI repetition. Results of the comparisions will be shown for all geomagnetic elements.Published351-3651A. Geomagnetismo e PaleomagnetismoN/A or not JC
