In this paper, we focus on the modeling of radial transport in the Earth’s outer radiation belt. A historical overview of the first observations of the radiation belts is presented, […]
Fast magnetosonic waves can lead to the local acceleration of electrons from ∼10 keV up to a few MeV on a timescale of 1–2 d and may play an important […]
Nonadiabatic loss processes of radiation belt energetic electrons include precipitation loss to the atmosphere due to pitch-angle scattering by various magnetospheric plasma wave modes. Here we consider electron precipitation loss […]
The principal loss mechanism for electrons from the inner radiation belt (1.2 < L < 2.0) and slot region (2.0 < L < 3.0) is atmospheric precipitation driven by several […]
Plasmaspheric hiss1 is a type of electromagnetic wave found ubiquitously in the dense plasma region that encircles the Earth, known as the plasmasphere2. This important wave is known to remove3, […]
Energetic electrons (≥50 keV) are injected into the slot region (2 < L < 4) between the inner and outer radiation belts during the early recovery phase of geomagnetic storms. […]
Wave-particle interactions lead to the loss of relativistic electrons from the outer radiation belt on timescales ranging from hours to weeks. For a fixed value of chorus wave amplitudes pitch-angle […]
Energetic electrons (E > 100 keV) in the Earth’s radiation belts undergo Doppler-shifted cyclotron resonant interactions with a variety of whistler mode waves leading to pitch angle scattering and subsequent […]
In the present paper, phase space density functions of the form f(v) = A N /v n are fitted to statistical distributions of suprathermal electron fluxes (E = 0.213–16.5 keV) […]
Using ray tracing and suprathermal electron distributions from CRRES, the final propagation latitudes of typical chorus rays are calculated as a function of L, MLT, AE, and initial wave normal […]
Local acceleration is required to explain electron flux increases in the outer Van Allen radiation belt during magnetic storms. Here we show that fast magnetosonic waves, detected by Cluster 3, […]
It has been suggested that, during the Pliocene (ca 5–1.8Ma), an El Niño state existed as a permanent rather than an intermittent feature; that is, the tropical Pacific Ocean was […]
