Nonlinear wave growth theory of coherent hiss emissions in the plasmasphere [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2015
AbstractRecent observations of plasmaspheric hiss emissions by the Van Allen Probes show that broadband hiss emissions in the plasmasphere comprise short‐time coherent elements with rising and falling tone frequencies. Based on nonlinear wave growth theory of whistler mode chorus emissions, we have examined the applicability of the nonlinear theory to ...

Van Allen Probes observation of plasmaspheric hiss modulated by injected energetic electrons [PDF]

open access: yesAnnales Geophysicae, 2018
Plasmaspheric hiss was observed by Van Allen Probe B in association with energetic electron injections in the outer plasmasphere. The energy of injected electrons coincides with the minimum resonant energy calculated for the observed hiss wave ...

Prompt responses of magnetospheric whistler-mode waves to solar wind dynamic pressure pulses

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Whistler-mode waves play a critical role in shaping the Earth’s radiation belts, and their spatiotemporal distribution is vital for forecasting and modeling geospace weather.

An empirical model of the global distribution of plasmaspheric hiss based on Van Allen Probes EMFISIS measurements

open access: yesEarth and Planetary Physics, 2020
Using wave measurements from the EMFISIS instrument onboard Van Allen Probes, we investigate statistically the spatial distributions of the intensity of plasmaspheric hiss waves.

Survey of ELF-VLF plasma waves in outer radiation belt observed by Cluster STAFF-SA experiment [PDF]

open access: yesAnnales Geophysicae, 2008
Various types of plasma waves have profound effects on acceleration and scattering of radiation belt particles. For the purposes of radiation belt modeling it is necessary to know statistical distributions of plasma wave parameters.

Identifying the source region of plasmaspheric hiss [PDF]

open access: yes, 2015
The presence of the plasmaspheric hiss emission around the Earth has been known for more than 50 years but its origin has remained unknown in terms of source location and mechanism.

Observations of Radiation Belt Losses Due to Cyclotron Wave-Particle Interactions [PDF]

open access: yes, 2020
Electron loss to the atmosphere plays a critical role in driving dynamics of the Earths Van Allen radiation belts and slot region. This is a review of atmospheric loss of radiation belt electrons caused by plasma wave scattering via Doppler-shifted ...

Modeling inward diffusion and slow decay of energetic electrons in the Earth\u27s outer radiation belt [PDF]

open access: yes, 2015
A new 3-D diffusion code is used to investigate the inward intrusion and slow decay of energetic radiation belt electrons (\u3e0.5 MeV) observed by the Van Allen Probes during a 10 day quiet period on March 2013.
