Field-aligned currents and ionospheric parameters deduced from EISCAT radar measurements in the post-midnight sector [PDF]

, 2002
International audienceAttempting to derive the field-aligned current (FAC) density using the EISCAT radar and to understand the role of the ionosphere on closing FACs, we conducted special radar experiments with the EISCAT radar on 9 October 1999.

South-north asymmetry of field-aligned currents in the magnetotail observed by Cluster [PDF]

, 2010
We statistically investigated features of the field-aligned current (FAC) distribution in plasma sheet boundary layers between 17 and 19 RE in the magnetotail using the curlometer technique to calculate the current from four-point magnetic field ...

Field-Aligned Currents in Saturn's Magnetosphere: Observations From the F-Ring Orbits [PDF]

, 2018
We investigate the azimuthal magnetic field signatures associated with high‐latitude field‐aligned currents observed during Cassini's F‐ring orbits (October 2016–April 2017).

Empirical models of the Earth’s ionosphere field-aligned currents: a review [PDF]

E3S Web of Conferences, 2023
In this paper, we present a review of empirical models of the Earth’s ionosphere field-aligned currents (FAC). In total, seven FAC models were considered. Iijima and Potemra’s model was one of the earliest ones.

A comparison of Cluster magnetic data with the Tsyganenko 2001 model. [PDF]

, 2007
As part of an investigation of the magnetic effects of external currents in the magnetosphere, we have compared two years of perigee Cluster data to the Tsyganenko 2001 (T01) field model.

Field-aligned currents in the magnetosphere

Geofísica Internacional, 1991
Las corrientes alineadas con el campo en la magnetosfera fluyen en todas partes, no s6lo a altas 1"-titudes sino también a medianas y bajas. Sin embargo, su detecci6n con satcHites solo ha sido posible en la región por encima de las zonas aurorales.

Storm time field-aligned currents and magnetosphere-ionosphere coupling process

地球与行星物理论评, 2022
Field aligned currents (FACs), also known as Birkland current, are flowing along the magnetic field line between the ionosphere and magnetosphere. They play an essential role in transferring mass, energy, and momentum from the magnetosphere to the ...

Determination of Auroral Electrodynamic Parameters From AMPERE Field‐Aligned Current Measurements

Space Weather, 2021
We calculate high latitude electrodynamic parameters using global maps of field‐aligned currents from the Active Magnetosphere and Planetary Response Experiment (AMPERE).

Kelvin-Helmholtz Vortices as an Interplay of Magnetosphere-Ionosphere Coupling

Frontiers in Astronomy and Space Sciences, 2022
The solar wind-magnetosphere interaction drives diverse physical processes on the flanks of Earth’s magnetopause, and in turn these processes couple to the ionosphere.

Filamentary Alfvénic structures excited at the edges of equatorial plasma bubbles [PDF]

Annales Geophysicae, 2007
Recent observations performed by the French DEMETER satellite at altitudes of about 710 km suggest that the generation of equatorial plasma bubbles correlates with the presence of filamentary structures of field aligned currents carried by Alfvén ...
