The unexpected origin of plasmaspheric hiss from discrete chorus emissions
Nature, 2008 Plasmaspheric hiss is a type of electromagnetic wave found ubiquitously in the dense plasma region that encircles the Earth, known as the plasmasphere. This important wave is known to remove the high-energy electrons that are trapped along the Earth's magnetic field lines, and therefore helps to reduce the radiation hazards to satellites and humans in ...

Statistical Properties of Plasmaspheric Hiss From Van Allen Probes Observations [PDF]
Journal of Geophysical Research: Space Physics, 2018 Van Allen Probes observations are used to statistically investigate plasmaspheric hiss wave properties. This analysis shows that the wave normal direction of plasmaspheric hiss is predominantly field aligned at larger L shells, with a bimodal ...

Mid-latitude and plasmaspheric hiss: A review
Planetary and Space Science, 1992Abstract A review of mid-latitude and plasmaspheric hiss-type emissions observed on ground-based stations and in the Earth's magnetosphere is presented. Different approaches to modelling of these emissions are discussed. It is pointed out that mid-latitude hiss emissions are most likely to be generated in the equatorial magnetosphere where the energy

A theoretical study of plasmaspheric hiss generation
Journal of Geophysical Research: Space Physics, 1983An investigation of the generation of plasmaspheric hiss by the whistler mode instability has been carried out. Using combined ray‐tracing and growth rate calculations, the path‐integrated growth rates of a large number of waves have been calculated using a distribution function of the form F ∝ E−n sinm α.

Statistical Analysis of Hiss Waves in Plasmaspheric Plumes Using Van Allen Probe Observations
Journal of Geophysical Research: Space Physics, 2019 Plasmaspheric hiss waves commonly observed in high‐density regions in the Earth's magnetosphere are known to be one of the main contributors to the loss of radiation belt electrons.

Novel Wave Models and Diffusion Coefficients for Plasmaspheric Hiss and Low Frequency Hiss
2021 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2021The Earth's inner magnetosphere is populated by a host of high frequency plasma waves which, via wave-particle interactions, can shape the dynamics of the terrestrial radiation belts. One of these is an incoherent whistler-mode plasma wave commonly referred to as hiss.

Storm-time variations of plasmaspheric ELF hiss
Journal of Atmospheric and Terrestrial Physics, 1982Abstract ELF and VLF observational data obtained from Intercosmos-3 (August 1970–November 1970) and Intercosmos-5 (December 1971–March 1972) satellites have been analyzed. During geomagnetic storms, the generation region of plasmaspheric hiss, which is usually located near the equatorial plane just within the plasmasphere, tends to move inwards ...

Plasmaspheric hiss observations in the evening and afternoon quadrants
Journal of Geophysical Research, 1975Data obtained with an Explorer-45 instrument for detecting the magnetic components of ELF signals propagating in the magnetosphere are examined, showing that the strongest, most persistent signals were plasmaspheric hiss from a few hundred to a few thousand Hertz. Broad-band signals of 25 milligamma were common.

Plasmaspheric hiss intensity variations during magnetic storms
Journal of Geophysical Research, 1974The storm time intensity variations of ELF electromagnetic emissions have been studied by using the Ogo 6 search coil magnetometer. Low-latitude signals exhibit a sharp low-frequency cutoff and are identified as plasmaspheric hiss. Such waves show pronounced intensification during the recovery phase of magnetic storms but remain close to background ...
