EMMA Geomagnetic field data

1-minute averages of the magnetic field variations recorded at 27 ground stations located in Italy and Europe along a meridional chain covering a large range in geographical latitude (from 70 to 42 degrees). The data are automatically collected in near real-time and updated every 15 minutes.
