Midlatitudinal Special Airglow Structures Generated by the Interaction Between Propagating Medium‐Scale Traveling Ionospheric Disturbance and Nighttime Plasma Density Enhancement at Magnetically Quiet Time

Geophysical Research Letters, 2019
This paper reports a special midlatitudinal medium‐scale traveling ionospheric disturbance (MSTID) event, accompanied by a poleward surge of airglow depletion/enhancement and a bifurcation of depletion during the magnetically quiet period.

Equatorial plasma bubble seeding by MSTIDs in the ionosphere [PDF]

Progress in Earth and Planetary Science, 2018
Occurrences of equatorial plasma bubbles (EPBs) and medium-scale traveling ionospheric disturbances (MSTIDs) were studied using GPS satellite data-based total electron content mapping, ionograms, and 630 nm all-sky airglow images observed over the South ...

Analysis of Ionospheric Disturbances Caused by the 2018 Bering Sea Meteor Explosion Based on GPS Observations [PDF]

Sensors, 2020
The Bering Sea meteor explosion that occurred on 18 December 2018 provides a good opportunity to study the ionospheric disturbances caused by meteor explosions. Total electron content (TEC) is the core parameter of ionospheric analysis.

The Observation of Traveling Ionospheric Disturbances Using the Sanya Incoherent Scatter Radar

Remote Sensing
In this study, we used the Sanya Incoherent Scatter Radar (SYISR) to observe the altitude profiles of traveling ionospheric disturbances (TIDs) during a moderate magnetic storm from 13 to 15 March 2022. Three TIDs were recorded, including two large-scale

MSTIDs impact on GNSS observations and its mitigation in rapid static positioning at medium baselines

Annals of Geophysics, 2016
Total electron content (TEC) fluctuation in the ionosphere is one of the main unresolved problems degrading ambiguity resolution and thus affect the reliability of satellite positioning.

Numerical Simulation of Perkins Instability in the Midlatitude F-Region Ionosphere: The Influence of Background Ionospheric Multi-Factors

Atmosphere
A numerical simulation of Perkins instability in the midlatitude F-region ionosphere is developed in this study. The growth of nighttime plasma density perturbation excited by Perkins instability was successfully reproduced.

Interactions between MSTIDs and Ionospheric Irregularities in the Equatorial Region Observed on 13–14 May 2013

Remote Sensing
We investigate the interactions between medium-scale traveling ionospheric disturbances (MSTIDs) and the equatorial ionization anomaly (EIA) as well as between MSTIDs and equatorial plasma bubbles (EPBs) on the night of 13–14 May 2013, based on ...

MSTID forecasting methodology and data inventory

, 2023
T-FORS project aims at providing new models able to interpret a broad range of observations of the solar corona, the interplanetary medium, the magnetosphere, the ionosphere and the atmosphere, and to issue forecasts and warnings for TIDs several hours ahead.

Self‐consistent generation of MSTIDs within the SAMI3 numerical model [PDF]

Journal of Geophysical Research: Space Physics, 2014
Abstract In this study, we use the three‐dimensional, physics‐based numerical model, SAMI3 (Sami3 is Another Model of the Ionosphere), to self‐consistently generate nighttime, electrified, medium‐scale traveling ionospheric disturbances (MSTIDs) at midlatitudes. These are the first numerical simulations to use the
