Performance of the double-thin-shell approach for studying nighttime medium-scale traveling ionospheric disturbances using two dense GNSS observation networks in Japan

Earth, Planets and Space
Electrodynamic coupling between the ionospheric E and F regions is widely recognized as the underlying mechanism for generating medium-scale traveling ionospheric disturbances (MSTIDs) during nighttime at midlatitudes.

Analysis of daytime medium-scale traveling ionospheric disturbances by two-dimensional maps of total electron content perturbation and ionograms

Учёные записки Казанского университета: Серия Физико-математические науки, 2017
To analyze midlatitude medium-scale traveling ionospheric disturbances (MSTIDs), the sufficiently dense network of GNSS receivers (more than 150 ground-based stations) have been used. For the first time, daytime MSTIDs in the form of their main signature
