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.

Anthropogenic Space Weather

TL;DR: In this article, the fundamental physical process behind the anthropogenic effects on the space environment is discussed and the observations of their impacts are discussed. But the authors do not consider the effects of high-altitude nuclear tests on the environment.

Simultaneous event-specific estimates of transport, loss, and source rates for relativistic outer radiation belt electrons

TL;DR: In this paper, the authors employ in situ measurements during the 13-14 January 2013 enhancement event to isolate transport, loss, and source dynamics in a one-dimensional radial diffusion model and validate the results by comparing them to Van Allen Probes and Time History of Events and Macroscale Interactions during Substorms observations.

Combined effects of concurrent Pc5 and chorus waves on relativistic electron dynamics

TL;DR: In this paper, electron phase space density (PSD) calculations as well as concurrent Pc5 and chorus wave activity observations during two intense geomagnetic storms caused by interplanetary coronal mass ejections (ICMEs) resulting in contradicting net effect.

Regular Article: A Solution-Adaptive Upwind Scheme for Ideal Magnetohydrodynamics

TL;DR: In this article, the authors present a computational scheme for compressible magnetohydrodynamics (MHD) based on the same elements that make up many modern compressible gas dynamics codes: high-resolution upwinding based on an approximate Riemann solver for MHD and limited reconstruction; an optimally smoothing multi-stage time-stepping scheme; and solution-adaptive refinement and coarsening.

Relativistic theory of wave‐particle resonant diffusion with application to electron acceleration in the magnetosphere

TL;DR: In this paper, a model was proposed to account for the observed variations in the flux and pitch angle distribution of relativistic electrons during geomagnetic storms by combining pitch angle scattering by intense EMIC waves and energy diffusion during cyclotron resonant interaction with whistler mode chorus outside the plasmasphere.

Pitch-angle diffusion of radiation belt electrons within the plasmasphere.

TL;DR: In this paper, the formation of the quiet-time electron slot, which divides the radiation belt electrons into an inner and an outer zone, was investigated. But the results were limited to the inner radiation zone.
