Unique Banded Structures of Plasmaspheric Hiss Waves in the Earth's Magnetosphere

Journal of Geophysical Research: Space Physics, 2023
Plasmaspheric hiss is an electromagnetic wave mode that occurs ubiquitously in the high‐density plasmasphere and contributes crucially to the dynamic behavior of the Earth's Van Allen radiation belts. While plasmaspheric hiss is commonly considered to be

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
The 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 ...

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

Journal of Geophysical Research: Space Physics, 2021
We 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

Analysis of Electron Precipitation and Ionospheric Density Enhancements Due To Hiss Using Incoherent Scatter Radar and Arase Observations

Journal of Geophysical Research: Space Physics, 2022
Plasmaspheric hiss can cause energetic electron precipitation from the magnetosphere to the Earth's upper atmosphere and affect the ionospheric electron density profiles.

Statistical Properties of Whistler‐Mode Hiss Waves in the Inner Radiation Belt

Journal of Geophysical Research: Space Physics, 2022
Using the Van Allen Probes A and B observations from 01 January 2013 to 28 February 2018, we surveyed statistically the occurrence rate, intensity, and propagation properties of hiss waves in the inner radiation belt (1.1 < L ≤ 2).

Empirical Loss Timescales of Slot Region Electrons due to Plasmaspheric Hiss Based on Van Allen Probes Observations

Journal of Geophysical Research: Space Physics, 2021
Based on Van Allen Probes observations, in this study we perform a statistical analysis of the spectral intensities of plasmaspheric hiss at L‐shells of 1.8–3.0 in the slot region.
