Abstract
- Decades lasting research on the pulsating aurora suggested that this phenomenon forms as result of interactions between the magnetospheric keVs electrons and whistler‐mode chorus waves. Arase satellite observation reported the direct evidence for this process confirming in situ measurement of highly correlated precipitated electrons and chorus wave activity. This paper presents the theoretical analysis of this observational event based on the SuperThermal Electron Transport (STET) code that simulates the highly dynamic environment of measured waves and particle data. Specifically, the STET code simulated results confirms the delicate loss‐cone observation results of this mission and further reveals the broader energy range of precipitated electron fluxes that was not measurable by Arase satellite. Key Points: Applying Arase satellite observations for the kinetic simulation of pulsating auroraSuperThermal Electron Transport (STET) code simulated precipitated electron fluxes driven by whistler‐mode chorus wavesRevealing hidden pulsating aurora dynamics in Arase observation using STET code [ABSTRACT FROM AUTHOR]
