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.

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 ...

Dependence of Energetic Electron Precipitation on the Geomagnetic Index Kp and Electron Energy [PDF]
Journal of Astronomy and Space Sciences, 2013 It has long been known that the magnetospheric particles can precipitate into the atmosphere of the Earth. In this paper we examine such precipitation of energetic electrons using the data obtained from low-altitude polar orbiting satellite ...

Response of the total ozone to energetic electron precipitation events [PDF]
Journal of Atmospheric and Solar-Terrestrial Physics, 2018 Abstract In this paper we investigate response of the total ozone column to energetic electron precipitation (EEP) observed by bremsstrahlung effect. The list of EEP events was prepared by members of the balloon experiments of the Lebedev Physical Institute.

Modelling the impact of energetic electrons on electron-acoustic instabilities and HF/UHF wave propagation in the ionospheric-like plasmas [PDF]
Scientific ReportsRecent studies reveal that ionospheric irregularities remain poorly understood due to the lack of models and observations capable of explaining the characteristics of the observed wave structures.

Seasonal dependence of energetic electron precipitation: Evidence for a global role of lightning [PDF]
Geophysical Research Letters, 2009 Analysis of the DEMETER spacecraft particle data shows that energetic electron precipitation exhibits a seasonal dependence consistent with lighting‐induced electron precipitation (LEP). Over the United States, energetic electron fluxes in the slot region (between L = 2 and 3) are significantly higher in the northern summer than in the winter ...

Exceptional middle latitude electron precipitation detected by balloon observations: implications for atmospheric composition [PDF]
Atmospheric Chemistry and Physics, 2022 Energetic particle precipitation leads to ionization in the Earth's atmosphere, initiating the formation of active chemical species which destroy ozone and have the potential to impact atmospheric composition and dynamics down to the troposphere.
