Empirically Estimated Electron Lifetimes in the Earth's Radiation Belts: Comparison With Theory [PDF]

Geophysical Research Letters, 2020
We compute quasilinear diffusion rates due to pitch angle scattering by various mechanisms in the Earth's electron radiation belts. The calculated theoretical lifetimes are compared with observed decay rates, and we find excellent qualitative agreement ...

Empirically Estimated Electron Lifetimes in the Earth's Radiation Belts: Van Allen Probe Observations [PDF]

Geophysical Research Letters, 2020
We use measurements from NASA's Van Allen Probes to calculate the decay time constants for electrons over a wide range of energies (30 keV to 4 MeV) and L values ( L = 1.3–6.0) in the Earth's radiation belts.

Chorus wave power at the strong diffusion limit overcomes electron losses due to strong diffusion [PDF]

Nature Communications
Earth’s radiation belts consist of high-energy charged particles trapped by Earth’s magnetic field. Strong pitch angle diffusion of electrons caused by wave-particle interaction in Earth’s radiation belts has primarily been considered as a loss process ...

Lightning-induced relativistic electron precipitation from the inner radiation belt [PDF]

Nature Communications
The Earth’s radiation belts are maintained by a number of acceleration, loss and transport mechanisms, and the electron fluxes at any given time are highly variable.

A slot region in the magnetosphere of Jupiter [PDF]

Nature Communications
Understanding the balance between charged particle acceleration and loss is central to radiation belt research. Jupiter’s Galilean moons orbit within its intense radiation environment and can act both as sources and sinks of energetic particles.

Influence of solar extreme ultraviolet radiations on artificial very-low-frequency waves in near-earth space [PDF]

Scientific Reports
Ground-based very low frequency (VLF) transmitter waves (3 – 30 kHz) can cause the precipitation loss of high-energy electrons in Earth’s radiation belts.

Distribution of Earth's radiation belts' protons over the drift frequency of particles [PDF]

Annales Geophysicae, 2021
Using data on the proton fluxes of the Earth's radiation belts (ERBs) with energy ranging from 0.2 to 100 MeV on the drift L shells ranging from 1 to 8, the quasi-stationary distributions over the drift frequency fd of protons around the Earth are ...

An operational approach to forecast the Earth’s radiation belts dynamics

Journal of Space Weather and Space Climate, 2021
The Ca index is a time-integrated geomagnetic index that correlates well with the dynamics of high-energy electron fluxes in the outer radiation belts.
