The Electric and Magnetic Field Instrument Suite and Integrated Science (EMFISIS) on RBSP

TLDR
The Electric and Magnetic Field Instrument and Integrated Science (EMFISIS) investigation on the NASA Radiation Belt Storm Probes (now named the Van Allen Probes) mission provides key wave and very low frequency magnetic field measurements to understand radiation belt acceleration, loss, and transport.
Abstract
The Electric and Magnetic Field Instrument and Integrated Science (EMFISIS) investigation on the NASA Radiation Belt Storm Probes (now named the Van Allen Probes) mission provides key wave and very low frequency magnetic field measurements to understand radiation belt acceleration, loss, and transport. The key science objectives and the contribution that EMFISIS makes to providing measurements as well as theory and modeling are described. The key components of the instruments suite, both electronics and sensors, including key functional parameters, calibration, and performance, demonstrate that EMFISIS provides the needed measurements for the science of the RBSP mission. The EMFISIS operational modes and data products, along with online availability and data tools provide the radiation belt science community with one the most complete sets of data ever collected.

Science Objectives and Rationale for the Radiation Belt Storm Probes Mission

TL;DR: The NASA Radiation Belt Storm Probes (RBSP) mission as discussed by the authors uses two spacecraft making in situ measurements for at least 2 years in nearly the same highly elliptical, low inclination orbits (1.1×5.8 RE, 10∘).

Rapid local acceleration of relativistic radiation-belt electrons by magnetospheric chorus

TL;DR: High-resolution electron observations obtained during the 9 October storm are reported and chorus scattering explains the temporal evolution of both the energy and angular distribution of the observed relativistic electron flux increase, and detailed modelling demonstrates the remarkable efficiency of wave acceleration in the Earth's outer radiation belt.

Magnetically self‐consistent ring current simulations during the 19 October 1998 storm

TL;DR: In this article, the effects of magnetic self-consistency on ring current development were investigated by calculating equatorial particle transport in a model that feeds back the ring current on the magnetospheric configuration.

Chorus source properties that produce time shifts and frequency range differences observed on different Cluster spacecraft

TL;DR: In this paper, the authors present an explanation of frequency range differences and time shifts between corresponding chorus elements of whistler mode chorus which have been recently observed on multiple Cluster spacecraft, and demonstrate that a nonmoving or quasi-static source that emits waves in a relatively narrow interval of wave normal angles and that varies both the wave normal angle and frequency during the generation of a single chorus element can reproduce these observations.
