Energetic Electron Precipitation Induced by Oblique Whistler Mode Chorus Emissions

Journal of Geophysical Research: Space Physics, 2021
Abstract Energetic electron acceleration and precipitation in the Earth's outer radiation belt are highly associated with wave‐particle interactions between whistler mode chorus waves and electrons. We perform test particle simulations to investigate electrons interacting with parallel and oblique chorus emissions

Electron Microbursts Induced by Nonducted Chorus Waves

Frontiers in Astronomy and Space Sciences, 2021
Microbursts, short-lived but intense electron precipitation observed by low-Earth-orbiting satellites, may contribute significantly to the losses of energetic electrons in the outer radiation belt. Their origin is likely due to whistler mode chorus waves,

Energetic electron precipitation into the atmosphere

, 2020
This chapter provides an overview of the impact of energetic electron precipitation from the aurora and the radiation belts on the composition, radiative balance, and dynamics of the Earth's atmosphere, from the lower thermosphere down to the surface. The primary processes related to atmospheric ionization and subsequent collision reactions that lead ...

On the fine structure of medium energy electron fluxes in the auroral zone and related effects in the ionospheric D-region [PDF]

, 2010
This study is based on measurements of trapped and precipitated electrons of energy >30 keV and >100 keV observed by polar orbiting environmental satellites during overpasses of the imaging riometer at Kilpisjärvi, Finland.

Investigation of the drivers and atmospheric impacts of energetic electron precipitation

Frontiers in Astronomy and Space Sciences, 2023
The drivers and atmospheric impacts of energetic electron precipitation are not yet well understood. Further, electron precipitation is often poorly represented in atmospheric modeling.

pyGPI5: A python D- and E-region chemistry and ionization model

Frontiers in Astronomy and Space Sciences, 2022
We present a Python implementation of a D- and E-region chemistry and ionization code called pyGPI5. Particle precipitation that penetrates into the E- and D-region of the ionosphere-thermosphere causes significant enhancements of the electron density ...

Dipolarization-induced energetic electron precipitation during continuously active periods and isolated substorms

Frontiers in Physics, 2022
Recently we proposed a spatio-temporal model of auroral absorption for isolated substorms based on linear prediction filter technique, which describes the precipitation effects as a sum of properly weighted and time-delayed contributions of short ...

Energetic electron precipitation from the inner zone

Geophysical Research Letters, 1997
Energetic electron precipitation flux from the Earth's inner radiation belt (L≤2) is usually below the detection threshold of current satellite instrumentation. Theoretical estimates of the longitudinally and interhemispherically averaged rate of precipitation have been obtained by evaluating the equilibrium electron pitch angle distribution in the ...

Effect of EMIC waves on relativistic and ultrarelativistic electron populations: Ground-based and Van Allen Probes observations [PDF]

, 2014
We study the effect of electromagnetic ion cyclotron (EMIC) waves on the loss and pitch angle scattering of relativistic and ultrarelativistic electrons during the recovery phase of a moderate geomagnetic storm on 11 October 2012.
