20 Years of Cluster Observations: The Magnetopause [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2021
AbstractThe terrestrial magnetopause forms the boundary between the solar wind plasma with its embedded interplanetary magnetic field on one side, and the terrestrial magnetosphere, dominated by Earth's dipole field, on the other side. It is therefore a key region for the transfer of mass, momentum, and energy from the solar wind to the magnetosphere ...

A generalization of the minimum variance analysis method [PDF]

open access: yesAnnales Geophysicae, 1996
In order to determine the normal direction of the magnetopause, the minimum variance analysis technique is frequently used: it is applied to the magnetic field data of a magnetopause crossing observed by a satellite, and provides the direction along ...

Modeling magnetopause location for 4D drift-resolved radiation belt codes: Salammbô model implementation [PDF]

open access: yesAnnales Geophysicae
We present a new semi-analytical magnetopause location model specifically designed for 4D drift-resolved radiation belt modeling codes. We specifically designed this magnetopause location model for the 4D version of Salammbô, but it can be adaptable to ...

The magnetopause shape and location: a comparison of the Interball and Geotail observations with models [PDF]

open access: yesAnnales Geophysicae, 2002
A number of magnetopause models have been developed in the course of last three decades. We have chosen seven of them and tested them using a fresh set of magnetopause crossings observed by Interball-1, Magion-4, and Geotail satellites.

Statistical survey of day-side magnetospheric current flow using Cluster observations: magnetopause [PDF]

open access: yesAnnales Geophysicae, 2017
We present a statistical survey of current structures observed by the Cluster spacecraft at high-latitude day-side magnetopause encounters in the close vicinity of the polar cusps.

Juno Magnetometer Observations at Ganymede: Comparisons With a Global Hybrid Simulation and Indications of Magnetopause Reconnection

open access: yesGeophysical Research Letters, 2022
Juno's flyby of Ganymede on 7 June 2021, provides a unique opportunity to explore the moon's magnetosphere. By means of Magnetometer (MAG) observations and a hybrid numerical simulation, we provide a global description of this environment and analyze the

Evolution of Kelvin-Helmholtz activity on the dusk flank magnetopause [PDF]

open access: yes, 2008
Our purpose is to characterize the evolution of the magnetopause Kelvin-Helmholtz (KH) wave activity with changes in thickness of the adjacent boundary layer, geomagnetic latitude and interplanetary magnetic field (IMF) orientation.

Coordinated polar spacecraft, geosynchronous spacecraft, and ground-based observations of magnetopause processes and their coupling to the ionosphere [PDF]

open access: yesAnnales Geophysicae, 2004
In this paper, we present in-situ observations of processes occurring at the magnetopause and vicinity, including surface waves, oscillatory magnetospheric field lines, and flux transfer events, and coordinated observations at geosynchronous orbit by ...

Thin electron-scale layers at the magnetopause [PDF]

open access: yes, 2004
We use data from the four Cluster satellites to examine the microphysics of a thin electron-scale layer discovered on the magnetospheric side of the magnetopause.

Spatial dependence of magnetopause energy transfer: Cluster measurements verifying global simulations [PDF]

open access: yesAnnales Geophysicae, 2011
We investigate the spatial variation of magnetopause energy conversion and transfer using Cluster spacecraft observations of two magnetopause crossing events as well as using a global magnetohydrodynamic (MHD) simulation GUMICS-4.
