Dissipation of field-aligned currents in the topside ionosphere [PDF]

Scientific Reports, 2022
Field-aligned currents (FACs) are electric currents parallel to the geomagnetic field and connecting the Earth’s magnetosphere to the high-latitude ionosphere.

Transient, small‐scale field‐aligned currents in the plasma sheet boundary layer during storm time substorms [PDF]

Geophysical Research Letters, 2016
We report on field‐aligned current observations by the four Magnetospheric Multiscale (MMS) spacecraft near the plasma sheet boundary layer (PSBL) during two major substorms on 23 June 2015.

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.

Online system for analyzing currents in the upper ionosphere according to Swarm satellite data

Solar-Terrestrial Physics, 2023
In this paper, we describe the TeslaSwarm online system [http://aleph.gcras.ru/teslaswarm] for visualizing field-aligned currents in the upper ionosphere, using data from Swarm low-orbit satellites.

A Third Generation Field‐Aligned Current Model [PDF]

Journal of Geophysical Research: Space Physics, 2020
AbstractA new empirical model of field‐aligned currents in the Earth's ionosphere has been developed. This model is derived using magnetometer data from the CHAallenging Minisatellite Payload, Ø rsted, and Swarm satellite missions, which has created a database that spans more than 15 years.

Statistical Analysis of Bifurcating Region 2 Field-Aligned Currents Using AMPERE

Frontiers in Astronomy and Space Sciences, 2022
We present a statistical analysis of the occurrence of bifurcations of the Region 2 (R2) Field-Aligned Current (FAC) region, observed by the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE).

Sign-Singularity Analysis of Field-Aligned Currents in the Ionosphere

Atmosphere, 2021
Field-aligned currents (FACs) flowing in the auroral ionosphere are a complex system of upward and downward currents, which play a fundamental role in the magnetosphere–ionosphere coupling and in the ionospheric heating.

Multiscale field‐aligned current analyzer [PDF]

Journal of Geophysical Research: Space Physics, 2015
AbstractThe magnetosphere‐ionosphere coupling is achieved, essentially, by a superposition of quasi‐stationary and time‐dependent field‐aligned currents (FACs), over a broad range of spatial and temporal scales. The planarity of the FAC structures observed by satellite data and the orientation of the planar FAC sheets can be investigated by the well ...

Field-aligned and ionospheric currents [PDF]

Planetary and Space Science, 1975
Abstract Zmuda and Armstrong (1974) showed that the field-aligned currents consist of two pairs; one is located in the morning sector and the other in the evening sector. Our analysis of magnetic records from the TRIAD satellite suggests that in each pair the poleward field-aligned current is more intense than the equatorward current, a typical ratio

Multipoint Field‐Aligned Current Estimates With Swarm [PDF]

Journal of Geophysical Research: Space Physics, 2019
AbstractField‐aligned currents (FACs) are a key component of the magnetosphere‐ionosphere system, providing the transfer of energy and momentum between the distant collision‐free magnetospheric plasma and the collisional ionosphere. The European Space Agency's Swarm mission offers a unique opportunity to explore the FACs low‐altitude end by a broad ...
