Substorm‐induced energetic electron precipitation: Impact on atmospheric chemistry [PDF]
Geophysical Research Letters, 2015 AbstractMagnetospheric substorms drive energetic electron precipitation into the Earth's atmosphere. We use the output from a substorm model to describe electron precipitation forcing of the atmosphere during an active substorm period in April–May 2007.

Spectral characteristics of waves and particles in the model of cyclotron wave-particle interactions near plasmapause [PDF]
Annales Geophysicae, 1999 Further analysis of energetic electron precipitation at the evening sector of magnetosphere is performed. In the framework of the quantitative model of cyclotron wave-particle interactions developed in the previous Pasmanik et al.

Solar wind drivers of energetic electron precipitation [PDF]
Journal of Geophysical Research: Space Physics, 2016 AbstractDisturbances of near‐Earth space are predominantly driven by coronal mass ejections (CMEs) mostly originating from sunspots and high‐speed solar wind streams (HSSs) emanating from coronal holes. Here we study the relative importance of CMEs and HSSs as well as slow solar wind in producing energetic electron precipitation.

Conjugate high-intensity energetic electron precipitation at high latitude [PDF]
Annales Geophysicae, 2003 On 6 August 1998 an intense precipitation event occurring at high latitude in the evening sector was observed by X-ray and far-ultraviolet imagers on board the Polar satellite and by several ground-based instruments.

Ionospheric Plasma Density Gradients Associated With Night‐Side Energetic Electron Precipitation
Geophysical Research Letters, 2023 Energetic electron precipitation from the equatorial magnetosphere into the atmosphere plays an important role in magnetosphere‐ionosphere coupling: precipitating electrons alter ionospheric properties, whereas ionospheric outflows modify equatorial ...

On the Effects of Bremsstrahlung Radiation During Energetic Electron Precipitation [PDF]
Geophysical Research Letters, 2018 AbstractPrecipitation of energetic particles into the Earth's atmosphere can significantly change the properties, dynamics, as well as the chemical composition of the upper and middle atmosphere. In this paper, using Monte Carlo models, we simulate, from first principles, the interaction of monoenergetic beams of precipitating electrons with the ...

Energetic outer radiation belt electron precipitation during recurrent solar activity [PDF]
Journal of Geophysical Research: Space Physics, 2010 Transmissions from three U.S. VLF (very low frequency) transmitters were received at Churchill, Canada, during an event study in May to November, 2007. This period spans four cycles of recurrent geomagnetic activity spaced ∼27 days apart, with daily ΣKp reaching ∼30 at the peaks of the disturbances.
