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.

Ring current asymmetry from global simulations using a high‐resolution electric field model

TL;DR: In this paper, the authors studied ring current evolution during the 10 January 1997 geomagnetic storm, comparing results from two inner magnetospheric convection electric field models: (1) the Kp-dependent Volland-Stern (V-S) model and (2) the high spatial and temporal resolution assimilative mapping of ionospheric electrodynamics (AMIE) model, coupled with our global ring current model.

Complete wave‐vector directions of electromagnetic emissions: Application to INTERBALL‐2 measurements in the nightside auroral zone

TL;DR: In this paper, the authors present several newly developed methods for wave propagation analysis based on simultaneous measurement of three magnetic field components and one or two electric field components, which are used to estimate complete wave vector direction and the refractive index.

Wave normal angles of magnetospheric chorus emissions observed on the Polar spacecraft

TL;DR: In this article, the authors characterize the distribution of the polar wave normal angle, θ, for chorus emissions as a function of magnetic latitude, λ, and show that wave normal angles with values θ < 20° have the highest probability of occurrence in the latitude range of 10°-50°.

electron drift echoes in the inner magnetosphere

TL;DR: In this paper, it was inferred from the drift rate that the energy of the electrons which were observed was in the range of 12 to 25 MeV and perhaps higher, and that the number of electrons that were observed in the inner magnetosphere was at most 2.6 to 2.1.
