Abstract

Satellite magnetic data include the slowly varying main field, the static lithospheric or crustal anomaly field, and fields associated with the regular daily variations of solar and lunar origin as well as magnetic disturbances. Satellite magnetic data are now available across a range of local times, and research is now being directed to studies of the daily variations from an ‘above the ionosphere’ point of view. The equatorial electrojet is easily seen in satellite orbits crossing the magnetic (dip) equator at local noon, and results are presented here for the satellite view of daily varying fields of ionospheric and magneto spheric origin.
