Electron Precipitation Observed by ELFIN Using Proton Precipitation as a Proxy for Electromagnetic Ion Cyclotron (EMIC) Waves

Geophysical Research Letters, 2023
Electromagnetic ion cyclotron (EMIC) waves can drive radiation belt depletion and Low‐Earth Orbit satellites can detect the resulting electron and proton precipitation.

Confirmation of EMIC wave‐driven relativistic electron precipitation [PDF]

Journal of Geophysical Research: Space Physics, 2016
AbstractElectromagnetic ion cyclotron (EMIC) waves are believed to be an important source of pitch angle scattering driven relativistic electron loss from the radiation belts. To date, investigations of this precipitation have been largely theoretical in nature, limited to calculations of precipitation characteristics based on wave observations and ...

Estimation of the characteristic energy of electron precipitation [PDF]

Annales Geophysicae, 2002
Data from simultaneous observations (on 13 February 1996, 9 November 1998, and 12 February 1999) with the IRIS, DASI and EISCAT systems are employed in the study of the energy distribution of the electron precipitation during substorm activity. The

Enhancement of thermospheric mass density by soft electron precipitation

Geophysical Research Letters, 2012
Enhancements in F‐region electron density and temperature and bottomside Pedersen conductivity caused by soft electron precipitation are shown to enhance the Joule heating per unit mass and the mass density of the thermosphere atF‐region altitudes.

Global Survey of Energetic Electron Precipitation at Low Earth Orbit Observed by ELFIN

Geophysical Research Letters
We statistically evaluate the global distribution and energy spectrum of electron precipitation at low‐Earth‐orbit, using unprecedented pitch‐angle and energy resolved data from the Electron Losses and Fields INvestigation CubeSats.

Theoretical Study of Interhemispheric Electron Bouncing Within Pulsating Aurora

Geophysical Research Letters, 2023
Wave‐particle interaction processes in the equatorial magnetosphere initiate time‐dependent electron precipitation in the pulsating aurora. These electrons enter loss‐cone and bounce between the two magnetically conjugate hemispheres, collide with the ...

Observed Loss of Polar Mesospheric Ozone Following Substorm‐Driven Electron Precipitation

Geophysical Research Letters, 2023
Several drivers cause precipitation of energetic electrons into the atmosphere. While some of these drivers are accounted for in proxies of energetic electron precipitation (EEP) used in atmosphere and climate models, it is unclear to what extent the ...

Intense Energetic Electron Precipitation Caused by the Self‐Limiting of Space Radiation

Geophysical Research Letters, 2023
Understanding intense electron precipitation is crucial for characterizing radiation belt loss and assessing related impacts on the atmosphere. We investigate the evolution of electron flux during an ensemble of 70 geomagnetic storms, focusing on ...
