A Spanish Geomagnetic Reference Field for epoch 1990 has been produced using the technique of spherical cap harmonic analysis (SCHA). The data set on which the model is based includes both Magsat and ground three-component data. The field data have been updated to 1990 by means of a spherical cap harmonic model of secular variation for a spherical cap of half-angle 16° for the time interval 1970-1989.5. Charts of the elements of the 1990 Spanish Geomagnetic Reference Field are shown, along with the secular variation maps for that epoch as deduced from the secular variation model. -from Authors
