Title

Modulation of energetic electron precipitation driven by three types of whistler mode waves

Abstract

Precipitation into the Earth's atmosphere due to pitch angle scattering by plasma waves has been recognized as one of the major loss mechanisms for energetic electrons. In this study, we quantitatively evaluate their roles in precipitating electrons during a conjunction event with modulated electron precipitation observed at low altitudes by Electron Loss and Fields INvestigation and three types of whistler mode waves (hiss, plume hiss, and chorus) measured near the equator by Time History of Events and Macroscale Interactions during Substorms. Electron precipitation was observed from similar to 50 keV to <1 MeV with a spatial modulation, suggested by a good correlation between L shell-sorted precipitation fluxes and wave intensities. A quasi-linear analysis supports the observed energy range of precipitation and the ratio of precipitating-to-trapped flux. Our findings reveal that the modulated energetic electron precipitation is driven by hiss, plume hiss, and chorus waves.
