Magnetospheric convection electric field dynamics andstormtime particle energization: case study of the magneticstorm of 4 May 1998 [PDF]

open access: yesAnnales Geophysicae, 2004
It is shown that narrow channels of high electric field are an effective mechanism for injecting plasma into the inner magnetosphere. Analytical expressions for the electric field cannot produce these channels of intense plasma flow, and thus, result ...

The Comprehensive Inner Magnetosphere‐Ionosphere Model [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2014
AbstractSimulation studies of the Earth's radiation belts and ring current are very useful in understanding the acceleration, transport, and loss of energetic particles. Recently, the Comprehensive Ring Current Model (CRCM) and the Radiation Belt Environment (RBE) model were merged to form a Comprehensive Inner Magnetosphere‐Ionosphere (CIMI) model ...

Storm time dynamics of ring current protons: Implications for the long‐term energy budget in the inner magnetosphere

open access: yesGeophysical Research Letters, 2016
Our investigation of the long‐term ring current proton pressure evolution in Earth's inner magnetosphere based on Van Allen Probes data shows drastically different behavior of the low‐ and high‐ energy components of the ring current proton population ...

Inner magnetosphere coupling: Recent advances [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2017
AbstractThe dynamics of the inner magnetosphere is strongly governed by the interactions between different plasma populations that are coupled through large‐scale electric and magnetic fields, currents, and wave‐particle interactions. Inner magnetospheric plasma undergoes self‐consistent interactions with global electric and magnetic fields.

Nowcast model for low‐energy electrons in the inner magnetosphere [PDF]

open access: yesSpace Weather, 2015
AbstractWe present the nowcast model for low‐energy (<200 keV) electrons in the inner magnetosphere, which is the version of the Inner Magnetosphere Particle Transport and Acceleration Model (IMPTAM) for electrons. Low‐energy electron fluxes are very important to specify when hazardous satellite surface‐charging phenomena are considered.

A comparison of energetic particle energization observations at MMS and injections at Van Allen Probes

open access: yesFrontiers in Astronomy and Space Sciences, 2023
In this study, we examine particle energization and injections that show energetic electron enhancements at both MMS in the magnetotail and Van Allen Probes in the inner magnetosphere.

Prediction of Proton Pressure in the Outer Part of the Inner Magnetosphere Using Machine Learning

open access: yesSpace Weather, 2023
The information on plasma pressure in the outer part of the inner magnetosphere is important for simulations of the inner magnetosphere and a better understanding of its dynamics.

Numerical considerations in simulating the global magnetosphere [PDF]

open access: yesAnnales Geophysicae, 2010
Magnetohydrodynamic (MHD) models of the global magnetosphere are very good research tools for investigating the topology and dynamics of the near-Earth space environment.

Plasma Waves in the Inner Magnetosphere [PDF]

open access: yes, 2021
AbstractUnderstanding the role of plasma waves, extending from magnetohydrodynamic (MHD) waves at ultra-low-frequency (ULF) oscillations in the millihertz range to very-low-frequency (VLF) whistler-mode emissions at frequencies of a few kHz, is necessary in studies of sources and losses of radiation belt particles.

IMF BY and the seasonal dependences of the electric field in the inner magnetosphere [PDF]

open access: yesAnnales Geophysicae, 2005
It is known that the electric field pattern at high latitudes depends on the polarity of the Y component of the interplanetary magnetic field (IMF BY) and season. In this study, we investigate the seasonal and BY dependences in the inner magnetosphere
