Global Archeomagnetic Field Model for the Past 7k Years: CALS7K.1 |
| We present a continuous global geomagnetic field models for the recent millennia: CALS7K.1 covering 7000 years from 5000~BC to 1950~AD. This model, however, has meanwhile become superseded by CALS7K.2. If you are not specifically interested in the older version CALS7K.1 please use CALS7K.2 ... |

Global Archeomagnetic Model for the Past 3k years: CALS3K.2 |
| We present a continuous global geomagnetic field models for the recent millennia: CALS3K.2 covering 3000 years from 1000~BC to 1950~AD. The model was determined by regularized least squares inversion of archeo- and paleomagnetic data using spherical harmonics in space and cubic B-splines i ... |

Global Declination of the past 7000 years |
| The animation is showing the development of geomagnetic declination at the Earth's surface between 5000 BC and 1950 AD from global model CALS7K.1. The model is based on globally distributed archeo- and paleomagnetic data. It reflects general trends of field evolution while the spatial an ... |

CALS7K.2 dipole moment |
| This is just the dipole moment prediction from geomagnetic field model CALS7K.2 for the years from 5000~BC to 1950~AD with uncertainty estimates. The resolution of the file is annual, but the actual resolution of the model is in the order of 100 years. The model was determined by regularize ... |
