Quantifying the Size and Duration of a Microburst‐Producing Chorus Region on 5 December 2017 [PDF]

Geophysical Research Letters, 2022
Microbursts are impulsive (30 keV) precipitation (FIREBIRD II and AC6 CubeSats, POES) to determine the size of the microburst‐producing chorus source region beginning on 5 December 2017.

Ducted propagation of chorus waves: Cluster observations [PDF]

Annales Geophysicae, 2011
Ducted propagation of whistler waves in the terrestrial magnetosphere-ionosphere system was discussed and studied long before the first in-situ spacecraft measurements.

Fine structure of large‐amplitude chorus wave packets

Geophysical Research Letters, 2014
AbstractWhistler mode chorus waves in the outer Van Allen belt can have consequences for acceleration of relativistic electrons through wave‐particle interactions. New multicomponent waveform measurements have been collected by the Van Allen Probes Electric and Magnetic Field Instrument Suite and Integrated Science's Waves instrument.

A Theoretical Framework of Chorus Wave Excitation [PDF]

Journal of Geophysical Research: Space Physics, 2022
AbstractWe propose a self‐consistent theoretical framework of chorus wave excitation, which describes the evolution of the whistler fluctuation spectrum as well as the suprathermal electron distribution function. The renormalized hot electron response is cast in the form of a Dyson‐like equation, which then leads to evolution equations for nonlinear ...

A “Trap‐Release‐Amplify” Model of Chorus Waves [PDF]

Journal of Geophysical Research: Space Physics, 2021
AbstractWhistler mode chorus waves are quasi‐coherent electromagnetic emissions with frequency chirping. Various models have been proposed to understand the chirping mechanism, which is a long‐standing problem in space plasmas. Based on analysis of effective wave growth rate and electron phase space dynamics in a self‐consistent particle simulation, we

Modeling the wave normal distribution of chorus waves [PDF]

Journal of Geophysical Research: Space Physics, 2013
The propagation and attenuation characteristics of lower band and upper band chorus waves are investigated by ray tracing, and the evaluation of Landau damping based on an empirical suprathermal electron model derived from Time History of Events and Macroscale Interactions during Substorms (THEMIS) data.

Distribution and Evolution of Chorus Waves Modeled by a Neural Network: The Importance of Imbalanced Regression

Space Weather, 2023
Whistler‐mode chorus waves play an essential role in the acceleration and loss of energetic electrons in the Earth’s inner magnetosphere, with the more intense waves producing the most dramatic effects. However, it is challenging to predict the amplitude

Multi‐Parameter Chorus and Plasmaspheric Hiss Wave Models [PDF]

Journal of Geophysical Research: Space Physics, 2020
AbstractThe resonant interaction of energetic particles with plasma waves, such as chorus and plasmaspheric hiss waves, plays a direct and crucial role in the acceleration and loss of radiation belt electrons that ultimately affect the dynamics of the radiation belts.

A review of frequency chirping mechanism of chorus waves in the Earth's magnetosphere

地球与行星物理论评, 2022
Whistler mode chorus waves are common and intense electromagnetic waves in the Earth's magnetosphere. They play a crucial role in magnetospheric electron dynamics by accelerating and scattering electrons over a wide energy range.

A statistical study of the spatial distribution and source-region size of chorus waves using Van Allen Probes data [PDF]

Annales Geophysicae, 2018
The spatial distribution and source-region size of chorus waves are important parameters for understanding their generation. In this work, we analyze over 3 years of continuous wave burst-mode data from the Van Allen Probes mission and build a data ...
