Review of ionospheric irregularities and ionospheric electrodynamic coupling in the middle latitude region [PDF]
Earth and Planetary Physics, 2021 This paper briefly reviews ionospheric irregularities that occur in the E and F regions at mid-latitudes. Sporadic E (ES) is a common ionospheric irregularity phenomenon that is first noticed in the E layer.

A comparison between large‐scale irregularities and scintillations in the polar ionosphere [PDF]
Geophysical Research Letters, 2016 A comparison tool has been developed by mapping the global GPS total electron content (TEC) and large coverage of ionospheric scintillations together on the geomagnetic latitude/magnetic local time coordinates. Using this tool, a comparison between large‐
