The distribution of plasmaspheric hiss wave power with respect to plasmapause location

Geophysical Research Letters, 2016
AbstractIn this work, Van Allen Probes data are used to derive terrestrial plasmaspheric hiss wave power distributions organized by (1) distance away from the plasmapause and (2) plasmapause distance from Earth. This approach is in contrast to the traditional organization of hiss wave power by L parameter and geomagnetic activity.

Competition between outer zone electron scattering by plasmaspheric hiss and magnetosonic waves [PDF]

Geophysical Research Letters, 2017
AbstractWe quantify the electron scattering effects of simultaneous plasmaspheric hiss and magnetosonic waves that occurred in two neighboring time intervals but with distinct wave intensity profiles on 21 August 2013. Their combined scattering is found capable of causing electron distribution variations largely distinguishable from the consequences of

Plasmaspheric hiss waves generate a reversed energy spectrum of radiation belt electrons

Nature Physics, 2019
Highly energetic electrons are trapped in the magnetic field of Earth’s radiation belts. The physical mechanisms driving the dynamics of the Van Allen belts can be understood from the electron’s energy spectrum, which is believed to be steeply falling with increasing energy.

Whistlers and plasmaspheric hiss: Wave directions and three‐dimensional propagation

Journal of Geophysical Research: Space Physics, 1993
Wave data from the DE 1 satellite showing simultaneously nonducted whistlers and hiss are analyzed to determine wave propagation directions. At L = 3.8 and a geographic latitude of λg = 12°S, the average wave normal directions of discrete whistlers are measured to be ∼51° for fnof;= 4.5 kHz and ∼60° for fnof;= 3.5 kHz, forming a small (<20°) angle ...

Precipitation Loss of Radiation Belt Electrons by Two‐Band Plasmaspheric Hiss Waves

Journal of Geophysical Research: Space Physics, 2020
AbstractA two‐band plasmaspheric hiss consisting of a low‐frequency band (normal hiss with the frequency below 2 kHz) and a high‐frequency band (locally generated hiss with the frequency up to 10 kHz) was observed on 6 January 2014 by the Van Allen Probes (He et al., 2019, https://doi.org/10.1029/2018GL081578).

Determining the global coherence of plasmaspheric hiss waves in the magnetosphere

2020
&lt;p&gt;Plasmaspheric hiss waves is important in the radiation belt. Previous papers have shown that considering the variability of wave parameters will improve the effectiveness of modeling wave-particle interactions in the Radiation Belt, but less is known about how rapidly (and by how much) wave characteristics vary.

CIMI simulations with newly developed multiparameter chorus and plasmaspheric hiss wave models

Journal of Geophysical Research: Space Physics, 2017
AbstractNumerical simulation studies of the Earth's radiation belts are important to understand the acceleration and loss of energetic electrons. The Comprehensive Inner Magnetosphere‐Ionosphere (CIMI) model considers the effects of the ring current and plasmasphere on the radiation belts to obtain plausible results.

Global Survey of Electron Precipitation due to Hiss Waves in the Earth’s Plasmasphere and Plumes

Journal of Geophysical Research: Space Physics, 2021
AbstractWe present a global survey of energetic electron precipitation from the equatorial magnetosphere due to hiss waves in the plasmasphere and plumes. Using Van Allen Probes measurements, we calculate the pitch angle diffusion coefficients at the bounce loss cone, and evaluate the energy spectrum of precipitating electron flux. Our ∼6.5‐year survey

Quantification of Energetic Electron Precipitation Driven by Plume Whistler Mode Waves, Plasmaspheric Hiss, and Exohiss [PDF]

Geophysical Research Letters, 2019
AbstractWhistler mode waves are important for precipitating energetic electrons into Earth's upper atmosphere, while the quantitative effect of each type of whistler mode wave on electron precipitation is not well understood. In this letter, we evaluate energetic electron precipitation driven by three types of whistler mode waves: plume whistler mode ...

Global Empirical Models of Wave Amplitudes and Normal Angles of Banded Plasmaspheric Hiss Obtained From Van Allen Probes Observations

Journal of Geophysical Research: Space Physics, 2023
AbstractThe unique banded structure of plasmaspheric hiss with an upper band above ∼200 Hz and a lower band below ∼150 Hz has been recently reported. Based on observations from the twin Van Allen Probes from 15 September 2012 to 30 June 2019, we statistically investigate the global distributions of amplitude and power‐weighted wave normal angle (WNA ...
