  • HISTMAG: a database of historical and archeological geomagnetic data
  • Geomagnetic field model for the past 4000 years: a field model (BIGMUDI) derived from HISTMAG. You can obtain Gauss coefficients or obtain geomagnetic time series for a location of your choice
  • IMMAB4: a geomagnetic field model of the last reversal
  • two geomagnetic models of geomagnetic field excursions
