Data from: Superposed epoch analysis of the energetic electron flux variations during CIRs measured by BD-IES
<p>The flux variations of energetic electrons is one of the most important topics to understand dynamic processes in the space environment and the forecast for high-energy electron burst. BD-IES, an imaging energetic electron spectrometer onboard a Chinese navigation satellite at an inclined geosynchronous orbit (IGSO), can provide 50-600keV electron flux data, which is used to investigate electron flux variations at GEO orbit during Co-rotating Interactive Region events (CIRs). The superposed epoch analysis is applied to study the electron flux variations in different energy channels of BD-IES during CIRs and the results support previous works. It reveals that electron fluxes in different channels all have a dropout before or at CIR interface and then the recovery of electrons with low energy reaches maximum earlier than that of electrons with high energy, with longer time difference for larger energy gap, which is consistent of two major mechanisms for energizing particles: inward radial diffusion and local acceleration. In addition, we investigate the relationship between electron flux enhancement in each energy channel and magnetic local time (MLT) and the extent of enhancement for electron flux peak value compared with average value before interface. These results can contribute to our understanding of electron flux variations at GEO during CIRs, and thus lay foundations for forecast research on high-energy electron burst during CIRs.</p>
