On the low latitude topside models: I. electron density
Abstract
Ion density measured within the scope of the ACTIVE Project was analyzed for range of +/-30 invariant latitude. Apogee (2500 km) and perigee (500 km) data of December 1989 and March 1990, though in general agreement with the IRI, show a distinct equatorial anomaly yet at altitude of 500 km. A small longitude effect appears at local early morning at apogee height. Geomagnetic activity causes an increase of density, particularly in apogee.
