Energetic Electron Diffusion and Precipitation Driven by Ducted Hiss Waves in High Density Irregular Region

Abstract Plasmaspheric hiss plays an important role in the electron precipitation and the slot formation in radiation belts. Recent studies show the whistler‐mode waves can be guided in the density irregularities, performing parallel propagation. Therefore, the resonance between ducted waves and energetic electrons can expand to higher latitudes, and then drive strong energetic electron scattering. In this study, we report a conjugate observation using data from Van Allen Probe A and POES. Through the analysis of observation and the quantification of quasi‐linear diffusion coefficients, the results show the ducted hiss can effectively scatter the energetic electrons and drive enhanced electron flux at low altitude region. We suggest the ducted hiss is important for electron loss process in radiation belts.

Abstract

Abstract Plasmaspheric hiss plays an important role in the electron precipitation and the slot formation in radiation belts. Recent studies show the whistler‐mode waves can be guided in the density irregularities, performing parallel propagation. Therefore, the resonance between ducted waves and energetic electrons can expand to higher latitudes, and then drive strong energetic electron scattering. In this study, we report a conjugate observation using data from Van Allen Probe A and POES. Through the analysis of observation and the quantification of quasi‐linear diffusion coefficients, the results show the ducted hiss can effectively scatter the energetic electrons and drive enhanced electron flux at low altitude region. We suggest the ducted hiss is important for electron loss process in radiation belts.
