13. Geomagnetic Pole 1900-2015

The GMPOLE program provides a determination of the Geomagnetic North Pole. The program uses a linear interpolation of the dipole Gauss coefficients from the geomagnetic reference field models (see file ALL-IGRF.TAB below). The fitting allows specification of any date from the first day of January 1900 to the projected values on the last day of December 2015. This program uses a computational method devised by Fraser-Smith (1987) and originally coded by W.H. Campbell. New version coded by Adam Woods. An example screen is shown below.
