The effect of the IMF on the magnetosheath is strongest (weakest) when the IMF is directed perpendicular (parallel) to the rotational equator. For any intermediate IMF orientation, a smooth rotation of the magnetosheath magnetic field towards the direction of the planet's rotational axis is ...
Data-based modeling of the magnetic field originating in the Earth’s ionosphere is challenging due to the multiple timescales involved and the small spatial scales of some of the current systems, especially the equatorial electrojet (EEJ) that flows along the magnetic dip equator. The Dedicated ...
In the “Evolution of the South Atlantic Anomaly as seen by Swarm” section, we report on the recent changes in the region of weakest field intensity and their origin at the core surface. In the section “Field acceleration changes in the Pacific region since 2014”, we focus on rapid ...
In this work, we report the first time ionosonde measurements from Dibrugarh (27.5° N, 95° E, 17° N geomagnetic, 43° dip) which lies in the same longitude as the strongest daytime longitudinal enhancement (90–100° E) in density, EEJ, and vertical E × B drift, etc. (Kil ...
