Internal source of plasmaspheric hiss on Earth

地球与行星物理论评, 2022
Plasmasphere is an upward extension of the ionosphere at low and middle latitudes along the closed magnetic field lines rooted in the Earth, where the trapped whistler-mode waves in the frequency range from tens to thousands of Hertz are named as ...

The upward propagating ionospheric hiss waves during the seismic time observed by the China seismo-electromagnetic satellite

Frontiers in Astronomy and Space Sciences, 2023
The ionospheric hiss wave is a broadband incoherent and structureless electromagnetic emission. They appear in a relatively narrower frequency range between −0.1 and 1.5 kHz. However, according to previous observations, abnormal electromagnetic emissions

The relationship between auroral hiss at high altitudes over the polar caps and the substorm dynamics of aurora [PDF]

Annales Geophysicae, 2005
Strong variations of intensity and cutoff frequency of the auroral hiss were observed by INTERBALL-2 and POLAR satellites at high altitudes, poleward from the auroral oval.

The Study on Modeling of Global Plasmaspheric Hiss Amplitude Based on Deep Learning Algorithm

Space Weather, 2023
Plasmaspheric hiss waves make great significance on the loss of electrons in the Earth's radiation belts. The prediction and reconstruction for global evolution plasmaspheric hiss are critical to investigate the dynamic process of radiation belt. In this

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

Geophysical Research Letters, 2016
In 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.

Hot plasma effects on the dispersion properties of plasmaspheric hiss and its electron diffusion

地球与行星物理论评, 2023
Electron diffusion caused by plasmaspheric hiss is an important mechanism for the loss of electrons in Earth's inner magnetosphere; it has also been considered responsible for the formation of the slot region between inner and outer radiation belts.

Multi‐Point Observation of Hiss Emerging From Lightning Whistlers

Journal of Geophysical Research: Space Physics, 2021
We analyze continuous multi‐point measurements of electromagnetic field waveforms onboard the Cluster spacecraft in order to contribute to the discussion on sources of plasmaspheric hiss, known as a shaping agent for the Earth radiation belts.

The Role of Hiss, Chorus, and EMIC Waves in the Modeling of the Dynamics of the Multi‐MeV Radiation Belt Electrons

Journal of Geophysical Research: Space Physics, 2020
In this study, we performed a series of long‐term and individual storm simulations with and without hiss, chorus, and electromagnetic ion cyclotron (EMIC) waves. We compared simulation results incorporating different wave modes with Van Allen Probes flux

Determining the Temporal and Spatial Coherence of Plasmaspheric Hiss Waves in the Magnetosphere

Journal of Geophysical Research: Space Physics, 2021
Plasmaspheric hiss is one of the most important plasma waves in the Earth's magnetosphere to contribute to radiation belt dynamics by pitch‐angle scattering energetic electrons via wave‐particle interactions.
