The Analysis and Forecast of The penetration of > 0.3 Mev Electrons to the Slot Region in Radiation Belt

Abstract

AbstractBased on the observations of the polar orbit satellite NOAA/POES during 1996~2006, characteristics of > 0.3 MeV electrons penetrating into the slot region in the radiation belt are studied. By comparing the properties of high energy electron penetration with the interplanetary condition, solar activity and geomagnetic disturbance, it is found that > 0.3 MeV electron penetration always takes place during magnetic storms. Also, the incidence of electron penetration has a correlation with solar activity cycle. Analysis of the correlation between > 0.3 MeV electron flux in the slot region and Dst index indicates that we can use Dst index to calculate the electron flux. In this case, we can establish a model to forecast the penetration of > 0.3 MeV electrons to the slot region in the radiation belt.
