A case study on multiple self-interactions of MSTID bands: New insights

Advances in Space Research, 2023
In this study, we report a special event of nighttime southwestward propagating medium scale traveling ionospheric disturbances (MSTIDs) observed in O(1D) 630.0 nm airglow images from an all-sky imager at Hanle (32.7°N, 78.9°E; Mlat. ~24.1°N), Ladakh, India on a geomagnetically quiet (Ap = 7) night of 15 September 2018.

The influence of ionospheric neutral wind variations on the propagation of a MSTID event

2021
<p>The event reports a special case of the propagation and morphology of medium scale travelling ionospheric disturbances (MSTIDs) over middle–latitude China. The MSTIDs were simultaneously observed by the all-sky imager, Swarm satellite, as well as the total electron content (TEC) from global positioning system (GPS).

Investigations of conjugate MSTIDS over the Brazilian sector during daytime

Journal of Geophysical Research: Space Physics, 2017
AbstractThis study focuses on the daytime medium‐scale traveling ionospheric disturbances (MSTIDs) observed at conjugate hemispheres. It is the first time that the geomagnetical conjugate daytime MSTIDs are observed over the South America sector. To observe the MSTID characteristics, we used detrended total electron content (TEC) derived from Global ...

Collocated ionosonde and dense GPS/GLONASS network measurements of midlatitude MSTIDs

Advances in Space Research, 2018
© 2017 COSPAR To analyze midlatitude medium-scale travelling ionospheric disturbances (MSTIDs) over Kazan (55.5°N, 49°E), Russia, the sufficiently dense network of GNSS receivers (more than 150 ground-based stations) were used. For the first time, daytime MSTIDs in the form of their main signature (band structure) on high-resolution two-dimensional ...

Statistical analysis of the occurrences of mstids observed by all-sky imager in low magnetic latitude

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
This research identified the occurrence of Medium-Scale Traveling Ionospheric disturbances (MSTIDs) during the ascending solar activity year 2010–2013 using the All-Sky Imager (ASI) mounted on Sirindhorn Observatory, Chiang Mai Thailand (18.8° N, 98.9° E, 13° dip latitude) to study the mechanism of the generation of irregularities in the ionosphere at ...

Analysis of MSTIDs triggered by dynamical events

It is well known that the ionosphere is a highly dynamic medium, and the electron density can vary significantly within a very short period of time at a given location. One of the reasons for the irregular variations are ionospheric signatures of Atmospheric Gravity Waves (AGWs) – Travelling Ionospheric Disturbances (TIDs).

Formation and evolution of nighttime MSTID modulated by the atmospheric tides

In this report, we utilize data from the multi-ground-based instruments of the Chinese Meridian Project (CMP) and public national websites, including red-line all-sky airglow imagers, digisondes, GNSS-TEC receivers, and so on, to conduct an in-depth investigation into the formation and evolution processes as well as the accompanying physical mechanisms

Characteristics of daytime medium scale traveling ionospheric disturbances (MSTIDs) as observed by SWARM

2020
<p><span>This paper studies the daytime medium scale traveling ionospheric disturbances (MSTIDs) in the mid- and low-latitude ionosphere for a period of nearly half a solar cycle (2014-2019) using SWARM observations.

Radar and Optical Observations of Irregular Midlatitude Sporadic E Layers Beneath MSTIDs

2011
An irregular sporadic E ionization layer was observed by the Arecibo incoherent scatter radar and a coherent scatter radar imager located on St. Croix during the passage of an MSTID observed by the Boston University all-sky camera in 630 nm imagery. The MSTID in question was not very intense and was barely detectable in the vertical F region plasma ...
