Coordinated EISCAT/DMSP measurements of electron density and energetic electron precipitation [PDF]

Journal of Geophysical Research: Space Physics, 1997
A campaign was recently undertaken to obtain simultaneous radar and satellite measurements that would provide insight into the temporal and spatial morphology of the energetic particle precipitation. It included coordinated field‐aligned measurements of the altitudinal profile of the E region electron density from the European Incoherent Scatter ...

A reexamination of latitudinal limits of substorm‐produced energetic electron precipitation [PDF]

Journal of Geophysical Research: Space Physics, 2013
AbstractThe primary sources of energetic electron precipitation (EEP) which affect altitudes <100 km (>30 keV) are expected to be from the radiation belts and during substorms. EEP from the radiation belts should be restricted to locations between L = 1.5 and 8, while substorm‐produced EEP is expected to range from L = 4 to 9.5 during quiet ...

Radiation belt electron acceleration by chorus waves during the 17 March 2013 storm [PDF]

, 2014
Local acceleration driven by whistler-mode chorus waves is fundamentally important for accelerating seed electron populations to highly relativistic energies in the outer radiation belt.

Competing source and loss mechanisms due to wave-particle interactions in Earth’s outer radiation belt during the 30 September to 3 October 2012 geomagnetic storm [PDF]

, 2014
Drastic variations of Earth’s outer radiation belt electrons ultimately result from various competing source, loss, and transport processes, to which wave-particle interactions are critically important.

Modeling of nonstationary electron precipitation by the whistler cyclotron instability [PDF]

Annales Geophysicae, 1998
We study a simple self-consistent model of a whistler cyclotron maser derived from the full set of quasi-linear equations. We employ numerical calculations to demonstrate dependencies of pulsation regimes of whistler-mode wave interactions with ...

X-Ray Emission from Jupiter, Saturn, and Earth: A Short Review [PDF]

, 2006
Jupiter, Saturn, and Earth - the three planets having dense atmosphere and a well developed magnetosphere - are known to emit X-rays. Recently, Chandra X-ray Observatory has observed X-rays from these planets, and XMM-Newton has observed them from ...

Energetic Electrons Near Europa From Juno JEDI Data

Geophysical Research Letters, 2023
Optical remote sensing observations have suggested that the top layer of Europa's icy surface is heavily affected by external weathering agents. To model and understand these effects, it is necessary to characterize the environment as fully as possible ...

Effect of the mirror force on the collision rate due to energetic electron precipitation: Monte Carlo simulations

Earth, Planets and Space, 2023
We study the effect of the mirror force on the collision rate due to the energetic electron precipitation into the ionosphere. We solve the motion of individual precipitating electrons with the mirror force, where collisions with neutral gas are computed

Quantifying hiss-driven energetic electron precipitation: A detailed conjunction event analysis [PDF]

, 2014
We analyze a conjunction event between the Van Allen Probes and the low-altitude Polar Orbiting Environmental Satellite (POES) to quantify hiss-driven energetic electron precipitation.
