The History of the Earth's Magnetic Field
This contribution contains updated geomagnetic field models spanning the past 3kyrs based on all available archeomagnetic and sedimentary paleomagnetic data as presented in M. Korte and C. Constable (submitted to Phys. Earth Planet. Int.): Improvements to millennial geomagnetic field reconstructions. Please see this publication for details on the models.
There are four ASCII files with model coefficients:
CALS3k.4, a new "high resolution" model
CALS3k.4b, a new more conservative model
CALS3k.3, a previous model for comparison
CALS3k.3b, a conservative version of the previous model
The included Fortran source code
produces time series of declination, inclination and intensity for any location on the Earth's surface from any of the four models.
produces similar time series with uncertainty estimates based on the MAST bootstrap from models CALS3k.4b or CALS3k.3b.
Geological Age Range and Timescale
0.003 Ma, Holocene
Unzip the archive and compile the Fortran code. Keep the model coefficient files in the same directory as the executable to run the programs.
