Observations of Energetic Particles From the Polar Cap to the Equator During the April 2002 Storms
Abstract
Geomagnetic storms can be studied from the polar cap to the equator at several local times using low-altitude spacecraft data. The unique data coverage offered by NOAA-15 and 16 is indeed very useful, since huge geomagnetic storms are affecting the ionosphere both at high and low latitudes. In the polar cap intense precipitation of MeV protons takes place, and at low L-values a Storm Time Equatorial Belt (STEB) of trapped protons and energetic neutral atoms appears. In this paper we employ multi-spacecraft data to study the April 2002 storms.
