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

open access: yesGeophysical 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.

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

open access: yesScientific 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.

Multiscale field‐aligned current analyzer [PDF]

open access: bronzeJournal 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 ...

On the role of neutral flow in field-aligned currents [PDF]

open access: goldAnnales Geophysicae, 2018
In this brief note we explore the role of the neutral atmosphere in magnetosphere–ionosphere coupling. We analyze momentum balance in the ion rest frame to form hypotheses regarding the role of neutral momentum in the lower ionosphere during ...

Field-aligned currents in the magnetosphere

open access: yesGeofísica 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.

Strong Nonideal Electric Fields and Energy Dissipation Observed by MMS within Field-Aligned Current Layers in the Plasma Sheet of the Earth’s Magnetotail [PDF]

open access: goldAtmosphere, 2023
We report the MMS observations of the intense spikes of field-aligned current (FAC) produced by magnetic reconnection at the plasma sheet (PS) field lines.

Space Technology 5 (ST-5) Observations of Field-Aligned Currents: Temporal Variability [PDF]

open access: green, 2010
Space Technology 5 (ST-5) is a three micro-satellite constellation deployed into a 300 x 4500 km, dawn-dusk, sun-synchronous polar orbit from March 22 to June 21, 2006, for technology validations.

Interplanetary Magnetic Field Bx Effect on Field-Aligned Currents in Different Local Times [PDF]

open access: goldRemote Sensing
This study explores the impact of the radial interplanetary magnetic field (IMF) on the strength and latitude of peak field-aligned currents (FACs). FACs are derived through vector magnetic field observations of the Swarm satellite mission.

Responses of Field‐Aligned Currents and Equatorial Electrojet to Sudden Decrease of Solar Wind Dynamic Pressure During the March 2023 Geomagnetic Storm [PDF]

open access: goldGeophysical Research Letters
We present the observations of field‐aligned currents and the equatorial electrojet during the 23 March 2023 magnetic storm, focusing on the effect of the drastic decrease of the solar wind dynamic pressure occurred during the main phase.
