Published in 2017 at "Journal of Geophysical Research"

DOI: 10.1002/2016ja023563

Abstract: Magnetometer data from three satellite missions have been used to analyze and identify the effects of varying solar radiation on the magnitudes and locations of field-aligned currents in the Earth's upper atmosphere. Data from the… read more here.

Published in 2017 at "Journal of Geophysical Research"

DOI: 10.1002/2017ja024372

Abstract: Many studies that have shown that the ionospheric, polar cap electric potentials (PCEP) exhibit a “saturation” behavior in response to the level of the driving by the solar wind. As the magnitude of the interplanetary… read more here.

Published in 2019 at "Geophysical Research Letters"

DOI: 10.1029/2019gl083283

Abstract: We analyze Magnetospheric Multiscale Mission observations of whistler waves and associated electron field‐aligned crescent distribution in the vicinity of the magnetotail near‐Earth X‐line. The whistler waves propagate outward from the X‐line in the neutral sheet.… read more here.

Published in 2020 at "Geophysical Research Letters"

DOI: 10.1029/2019gl086722

Abstract: Global Navigation Satellite Systems (GNSS) are subject to disturbances caused by plasma irregularities in the ionosphere. Studies have suggested that in addition to the gradient drift and Kelvin‐Helmholtz instabilities, electron precipitation may be important for… read more here.

Published in 2021 at "Earth and Space Science"

DOI: 10.1029/2020ea001167

Abstract: The locations of region 1 and 2 field‐aligned current systems were determined using fluxgate magnetometer measurements from 875 dawn‐dusk passes of the Swarm A satellite. Within each field‐aligned current region, the ionospheric Pedersen conductance was… read more here.

Published in 2025 at "Geophysical Research Letters"

DOI: 10.1029/2024gl111958

Abstract: In this work, we identified 65 auroral arcs that stretched out from the equatorward boundary of auroral oval with azimuthal extensions, and investigated their upstream triggering, by utilizing conjunctions between the THEMIS probes and the… read more here.

Published in 2025 at "Space Weather"

DOI: 10.1029/2025sw004573

Abstract: Field‐aligned currents (FACs) are the main physical mechanism behind magnetosphere–ionosphere coupling, with these currents communicating environmental changes between the two regions of geospace. Field‐aligned currents are thus a key factor in monitoring space weather, both… read more here.
