Geomagnetic survey of Italy. Repeat station network and magnetic maps: a short report

Starting in 1977, two geomagnetic project were undertaken in the frame of the <<Progetto Finalizzato Geodinamica>>of the Consiglio Nazionale delle Ricerche(Project<<Geodynamics>>of the National Research Council);1)a new national network of repeat stations for total field F, horizontal component H, vertical component Z, declination D.2)a 2nd order network of stations for F,Z,H to produce geomagnetic maps of Italy. The two projects were carried out by a <<Geomagnetism Group>> made up of Operating Units from Institutions to which the authors belong. The field work ended in 1981. The Istituto Nazionale di Geofisica coordinated the operations for both projects. This paper is intended to give a short report to the international scientific community on this work which has so far only appeared in the Italian literature.
