Electron Microbursts Induced by Nonducted Chorus Waves [PDF]

Frontiers in Astronomy and Space Sciences, 2021
Microbursts, short-lived but intense electron precipitation observed by low-Earth-orbiting satellites, may contribute significantly to the losses of energetic electrons in the outer radiation belt. Their origin is likely due to whistler mode chorus waves,

A new method for detection of microbursts via point observation methods and field measurement for validation study with Doppler weather radar. [PDF]

PLoS ONE
Wind shear (WS) phenomena are critical in many applications, especially in aviation, wind energy and urban planning. Microburst (MB) detection is important for ensuring safety during aircraft landing/takeoff, eliminating imbalances caused by shear from ...

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.

Proton aurora and relativistic electron microbursts scattered by electromagnetic ion cyclotron waves

Frontiers in Astronomy and Space Sciences, 2022
Charged particle precipitation from Earth’s magnetosphere results in stunning displays of the aurora and energy transfer into the atmosphere. Some of this precipitation is caused by wave-particle interactions.

The Repetition Period of MeV Electron Microbursts as Measured by SAMPEX/HILT

Geophysical Research Letters, 2023
Here we examine properties of MeV electron microbursts to better understand their generation mechanisms. Using 15 years of data from Solar, Anomalous, Magnetospheric Particles Explorer/Heavy Ion Large Telescope, >1 MeV microburst repetition periods (time

Association of Relativistic Electron Microbursts Duration With Chorus Wave Properties

Geophysical Research Letters
Relativistic electron microbursts are correlated with resonant scattering by whistler‐mode chorus waves. Here, we use chorus wave properties obtained from Van Allen Probe A to calculate the duration of relativistic microbursts.

Lightning-induced relativistic electron precipitation from the inner radiation belt [PDF]

Nature Communications
The Earth’s radiation belts are maintained by a number of acceleration, loss and transport mechanisms, and the electron fluxes at any given time are highly variable.

The detection of ultra-relativistic electrons in low Earth orbit [PDF]

Journal of Space Weather and Space Climate, 2018
Aims. To better understand the radiation environment in low Earth orbit (LEO), the analysis of in-situ observations of a variety of particles, at different atmospheric heights, and in a wide range of energies, is needed. Methods.

Test Particle Simulations of Dual‐Component Microbursts Observed by BARREL: Effects of Atmospheric Backscattering and Chorus Elements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Electron microbursts are among the most important loss mechanisms for energetic electrons in the Earth's radiation belts and are often driven by wave‐particle interactions with discrete chorus wave elements. Observations from the Balloon Array for Radiation‐belt Relativistic Electron Losses (BARREL) mission have revealed microburst events with
