Summary

Values of the geomagnetic field vector components computed from measurements made on land, at sea and in the air since 1900 all round the world. Repeat station data (collected at one location over many years and reduced to a magnetically quiet level) are an important part of this dataset. These data are useful for charting the Earth's magnetic field on time scales of years to decades.
