International audience; Relativistic electrons dynamics is still challenging to predict during the main phase of a storm. In particular, three dimensions radiation belt models, for which temporal resolution is limited, fail in predicting their behavi

International audience; The existence of high energy (E>1 MeV) electrons in the inner zone is always a debate issue. This study aims at answering this question using both simulation-based and data measurements evidences. First, using NOAA measurement

Whistler mode chorus is an important magnetospheric emission, playing a dual role in the acceleration and loss of relativistic electrons in the Earth's outer radiation belt. Chorus is typically generated in the equatorial region in the frequency rang
