NOAA/POES observation of the sources of the relativistic electron in the magnetosphere
基于NOAA/POES卫星观测的磁层相对论电子起源的初探

Using data from low-altitude polar orbit satellite of NOAA and ACE,we investigate the possible sources of the enhancement of relativistic electron in the magnetosphere.The observation from NOAA for the different geomagnetic activity period show that substorm injections provide seed electrons for MeV electron enhancement associated with geomagnetic storms and that energetic electrons in the solar wind provide an alternative sources for the relativistic electrons in the magnetosphere during the SEP(Solar Energetic Proton) events.
