Comparative statistical study of mid-latitude MSTIDs over two latitudinal regions using dense GNSS network

, 2021
This work is devoted to potential sources and mechanisms of the mid-latitude MSTIDs formation based on the analysis and comparison of statistical data in two regions: 1 region near Samara ( 55 N. 50 E), 2 region near Sevastopol ( 45 N, 35 E).

Evidence for Deep Ingression of the Midlatitude MSTID Into As Low as ~3.5° Magnetic Latitude [PDF]

Journal of Geophysical Research: Space Physics, 2019
An observational evidence of medium‐scale traveling ionospheric disturbances (MSTIDs) reaching to magnetic latitude as low as ~3.5° over the Indian sector is provided for the first time based on OI 630‐nm airglow imaging observation from a low‐latitude station, Gadanki (13.5°N, 79.2°E; 6.6° magnetic latitude), on 12 January 2016.

Gravity Wave Influences on MSTID Climatology Over CONUS: WACCM‐X Year‐Long Simulation and GNSS Long‐Term Observation

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Medium‐Scale Traveling Ionospheric Disturbances (MSTIDs) are prominent wave‐like structures in the ionosphere, with complex generation mechanisms involving both atmospheric gravity waves (GWs) and electrodynamic instabilities such as the Perkins instability (PI).

First Detection of the Two‐Dimensional Vertical Propagation of Traveling Ionospheric Disturbances Associated With Atmospheric Gravity Waves in the Martian Ionosphere

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract We report the detection of a traveling ionospheric disturbance (TID) captured by the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) Active Ionospheric Sounding (AIS) instrument aboard the Mars Express spacecraft at 150–250 km altitude.

Ionospheric Response to the 8 April 2024 Total Solar Eclipse: Plasma Depletion and Eclipse‐Driven MsTIDs

Space Weather, Volume 24, Issue 4, April 2026.
Abstract The total solar eclipse on 8 April 2024 provided a unique opportunity to investigate the three‐dimensional (3‐D) ionospheric response under enhanced solar activity over North America. In this study, we processed high‐density GNSS observations from ∼1,700 stations to derive vertical total electron content and applied a multi‐term sinusoidal ...

First Comprehensive Study of MSTID Generation and Propagation Characteristics in Iran

Journal of Geophysical Research: Space Physics
AbstractTo investigate medium‐scale TID (MSTIDs) at mid‐latitudes across Iran, TEC data obtained from a dense ground‐based GNSS receiver during the 7 months from May–November 2021 were analyzed. To remove the diurnal variability of the TEC, an 8th‐order Butterworth bandpass filter was applied to the data. Then, two‐dimensional TEC maps of the detrended
