This paper provides a brief review of ionospheric irregularities that occur in magnetically
equatorial and low-latitude regions post-midnight during low solar activity periods …

Over the past decades significant progresses have been done to understand the origin of
seeding mechanisms of ionospheric irregularities. However, characterization of the global …

Two‐dimensional total electron content (TEC) perturbations over Japan are mapped with the
Geographical Survey Institute (GSI) GPS network, GEONET (GPS Earth Observation …

Two-dimensional structures of medium-scale traveling ionospheric disturbances (MSTIDs)
over Europe have been revealed, for the first time, by using maps of the total electron …

We report for the first time simultaneous observations of medium‐scale traveling ionospheric
disturbances (MSTIDs) at geomagnetic conjugate points in both hemispheres, using two all …

Using global positioning system (GPS) data taken from 350 dual-frequency GPS receivers in
Southern California in 2002, we investigated two-dimensional maps of total electron content …

This paper presents a summary of 630.0 nm emission observations made by the Cornell All‐
Sky Imager that have revealed an abundance of structure in the midlatitude thermosphère …

In part 1 of our series exploring the role of electrical forces in midlatitude spread F, we
present observations of an electrodynamically driven traveling ionospheric disturbance …

The 15‐month climatology of medium‐scale traveling ionospheric disturbances (MSTIDs)
during a solar minimum period has been constructed from observations of a dense GPS …

Using global positioning system (GPS) data taken from the International GNSS Service
(IGS), we investigated total electron content (TEC) perturbations associated with medium …
