Storm Time Electrified MSTIDs Observed over Mid-Latitude North America

Journal of Geophysical Research: Space Physics, 2022
Medium-scale Traveling Ionospheric Disturbances (MSTIDs) are prominent and ubiquitous features of the mid-latitude ionosphere, and are observed in Super Dual Auroral Radar Network (SuperDARN) and high-resolution Global Navigational Satellite Service (GNSS) Total Electron Content (TEC) data.

Propagation of Perturbations in the Lower and Upper Atmosphere over the Central Mediterranean, Driven by the 15 January 2022 Hunga Tonga-Hunga Ha’apai Volcano Explosion

Atmosphere, 2022
The Hunga Tonga-Hunga Ha’apai volcano (Pacific Ocean) generated a cataclysmic explosion on 15 January 2022, triggering several atmospheric disturbances at a global scale, as a huge increase in the total electron content (TEC) in the ionosphere, and a ...

First Simultaneous Observation of a Night Time Medium‐Scale Traveling Ionospheric Disturbance From the Ground and a Magnetospheric Satellite [PDF]

, 2021
Medium-scale traveling ionospheric disturbances (MSTIDs) are a phenomenon widely and frequently observed over the ionosphere from high to low latitudes. Night time MSTIDs are caused generally by the polarization electric field in the ionosphere. However,

Tandem Observations of Nighttime Mid‐Latitude Topside Ionospheric Perturbations

Space Weather, 2023
Nighttime medium‐scale traveling ionospheric disturbances (MSTIDs) have been generally observed by ground‐based instruments. However, they provide 2‐dimensional images over only a limited field of view and are not distributed globally.

On the Ionospheric Disturbances in New Zealand and Australia Following the Eruption of the Hunga Tonga‐Hunga Ha'apai Volcano on 15 January 2022

Space Weather, 2023
The Hunga Tonga‐Hunga Ha'apai (hereafter HTHH) submarine volcano erupted at 04:14:45 UT on 15 January 2022, causing ionospheric disturbances. This paper uses carrier phase observations from GNSS tracking stations in New Zealand and Australia to calculate

Interrelation of traveling ionospheric disturbances above and below the F-layer peak according to the ionosonde and the SWARM constellation data

Учёные записки Казанского университета: Серия Физико-математические науки, 2019
One approach to determining the height structure of the mid-latitude medium-scale travelling ionospheric disturbances (MSTIDs) above the F layer peak is to involve simultaneous satellite measurements in the ground-based ionosonde measurements near Kazan.

Review of ionospheric irregularities and ionospheric electrodynamic coupling in the middle latitude region

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.
