Geomagnetic Coordinates 1940-2005
Entry ID: GMCORD

Summary
Abstract: The GMCORD program provides a determination of the geomagnetic coordinates for
any selected global location. The program uses a polynomial fit (see POLYFIT
program below) 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 1940 to the projected values on the last
day of December 2005. In addition to the computation of the dipole coordinates,
the geomagnetic pole locations, the dipole moment, and station dipole field
values are displayed on your screen. This program uses a computational method
devised by Fraser-Smith (1987) and coded by W.H. Campbell.
