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.

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.
