Short-duration Electron Precipitation Studied by Test Particle Simulation [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2015
Energy spectra of electron microbursts from 170 keV to 340 keV have been measured by the solid-state detectors aboard the low-altitude (680 km) polar-orbiting Korean STSAT-1 (Science and Technology SATellite).

Anisotropic pitch angle distribution of ~100 keV microburst electrons in the loss cone: measurements from STSAT-1 [PDF]

open access: yesAnnales Geophysicae, 2012
Electron microburst energy spectra in the range of 170 keV to 360 keV have been measured using two solid-state detectors onboard the low-altitude (680 km), polar-orbiting Korean STSAT-1 (Science and Technology SATellite-1).

Large-Eddy Simulation of a microburst [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
The three-dimensional structure and evolution of an isolated and stationary microburst are simulated using a time-dependent, high resolution Large-Eddy-Simulation (LES) model.

Catching the Microburst Culprits with Snappy [PDF]

open access: yesProceedings of the Afternoon Workshop on Self-Driving Networks, 2018
Short-lived traffic surges, known as microbursts, can cause periods of unexpectedly high packet delay and loss on a link. Today, preventing microbursts requires deploying switches with larger packet buffers (incurring higher cost) or running the network at low utilization (sacrificing efficiency).

Microbursts at Meter-Decameter Wavelengths [PDF]

open access: yesSymposium - International Astronomical Union, 1990
A statistical analysis of Clark Lake microbursts was performed using a data base consisting of ~ 100 bursts. The results are: (1) Microburst sources are well correlated with coronal streamers and active regions. (2) The peak brightness temperature (T^) of the microbursts is in the range 6 × 105 K to 6 × 107 K (see Fig.

Relativistic Microburst Scale Size Induced by a Single Point‐Source Chorus Element

open access: yesGeophysical Research Letters, 2022
Relativistic microbursts are impulsive, sub‐second precipitation bursts of relativistic electrons. They are one of the main loss mechanisms of outer radiation belt electrons, and are driven by chorus waves.

Micrometeorological Observations of a Microburst in Southern Finland [PDF]

open access: yesBoundary-Layer Meteorology, 2007
On the afternoon of 3 July 2004 in Hyytiälä (Juupajoki, Finland), convective cells produced a strong downburst causing forest damage. The SMEAR II field station, situated near the damage site, enabled a unique micrometeorological analysis of a microburst with differences above and inside the canopy.

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

open access: yesGeophysical 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.

Evidence of Microbursts Observed Near the Equatorial Plane in the Outer Van Allen Radiation Belt

open access: yesGeophysical Research Letters, 2018
We present the first evidence of electron microbursts observed near the equatorial plane in Earth's outer radiation belt. We observed the microbursts on 31 March 2017 with the Magnetic Electron Ion Spectrometer and Radiation Belt Storm Probes Ion ...
