The Comprehensive Inner Magnetosphere-Ionosphere Model

Inductive magnetosphere–ionosphere coupling

Inductive coupling of a global magnetospheric model to a global ionospheric–thermospheric model is described. Existing schemes based on electrostatic coupling are valid for magnetospheric variability occurring on time scales of order 100 s or longer. The formulation developed here extends the validity of the coupling model to time scales of order 10 s, while retaining the physics of quasi-stati...

Saturn: atmosphere, ionosphere, and magnetosphere.

The Cassini spacecraft has been in orbit around Saturn since 30 June 2004, yielding a wealth of data about the Saturn system. This review focuses on the atmosphere and magnetosphere and briefly outlines the state of our knowledge after the Cassini prime mission. The mission has addressed a host of fundamental questions: What processes control the physics, chemistry, and dynamics of the atmosphe...

Multiscale electrodynamics of the ionosphere-magnetosphere system

[1] In this paper we investigate how the parameters of the ionosphere and the low-altitude magnetosphere mediate the formation and spatiotemporal properties of small-scale, intense electromagnetic structures commonly observed by low-altitude satellites in the auroral and subauroral magnetosphere. The study is based on numerical modeling of a time-evolving, nonlinear system that describes multis...

Non-Potential Electric Field Model of Magnetosphere-Ionosphere Coupling

Magnetosphere-ionosphere coupling currents in Jupiter’s middle magnetosphere: effect of magnetosphere-ionosphere decoupling by field-aligned auroral voltages

We consider the effect of field-aligned voltages on the magnetosphere-ionosphere coupling current system associated with the breakdown of rigid corotation of equatorial plasma in Jupiter’s middle magnetosphere. Previous analyses have assumed perfect mapping of the electric field and flow along equipotential field lines between the equatorial plane and the ionosphere, whereas it has been shown t...
