TL;DR: In this article , traveling ionospheric disturbances (TIDs) radially outbound and inbound along entire Great-Circle loci at primary speeds of ∼300-350 m/s and 500-1,000 km horizontal wavelength for front shocks, going around the globe for three times, passing six times over the continental US in 100 h since the Tonga volcano eruption.

TL;DR: In this paper, the in situ electron density obtained with the Langmuir probe and the total electron content from onboard global positioning system receiver are used to detect ionospheric plasma irregularities, and the irregularity parameters from the electron density in terms of the rate of change of density index and electron density gradients.

TL;DR: In this paper, the spatial and seasonal distributions of the patches identified separately by Swarm A and Swarm B between December 2013 and August 2016 were computed for both hemispheres, and it was shown that in the NH the number of patches is higher in the postnoon and prenoon sectors for interplanetary magnetic field (IMF) By 0, and that this trend is mirrored in the SH, consistent with the ionospheric flow convection.

TL;DR: In this article, the relative scintillation level associated with cusp dynamics (including precipitation, flow shears, etc.) with and without the formation of polar cap patches around the cusp inflow region was investigated.
