INGV definitive geomagnetic data: Duronia

1-minute averages of the components (X, Y, Z in the NEC, i.e. North-East-Center frame) and of total intensity (F) of the Earth’s geomagnetic field measured at Duronia magnetic observatory (IAGA code: DUR Latitude: 41.650000° Longitude: 14.466000° Altitude: 895.000 m). These are the definitive values that will be used to calculate GICx and GICy indices. These data are definitive, new definitive data are added yearly. They can be retrieved from in json format from a web service so that the size of the file (estimated in the DATA DESCRIPTION TAB) actually depends on the query. Queries for a few-days data obtain a rapid reply while for longer queries (say from 1-month upward) obtain slow replies.
