Direct MSTID mitigation in precise GPS processing [PDF]
Radio Science, 2017 AbstractIn this paper, the authors summarize a simple and efficient approach developed to mitigate the problem in precise Global Navigation Satellite Systems (GNSS) positioning originated by the most frequent ionospheric wave signatures: the medium‐scale traveling ionospheric disturbances (MSTIDs).

Multitaper analysis of an MSTID event above Antarctica on 17 March 2013
Polar Science, 2021 Abstract A medium-scale travelling ionospheric disturbance (MSTID) was observed concomitantly by SANAE and Halley SuperDARN HF radars during the period 02–06 UT 17 March 2013. The event occurred during a geomagnetically quiet time where no substorm or storm activities were observed.

Multi-instrument observations of an MSTID over Arecibo Observatory [PDF]
2011 XXXth URSI General Assembly and Scientific Symposium, 2011 The Penn State All-Sky Imager (PSASI) at Arecibo Observatory provides planar horizontal context to the vertical ionospheric profiles obtained by the Incoherent Scatter Radar (ISR). Electric field measurements from the Communication/Navigation Outage Forecast System (C/NOFS) satellite are mapped down geomagnetic field lines to the height of the airglow ...

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.

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.

First Comprehensive Study of MSTID Generation and Propagation Characteristics in Iran
Journal of Geophysical Research: Space PhysicsAbstractTo 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

Equatorial Plasma Bubble Occurrence Under Propagation of MSTID and MLT Gravity Waves
Journal of Geophysical Research: Space Physics, 2020 AbstractWe observed a signature of equatorial plasma bubbles (EPBs) followed by a medium‐scale traveling ionospheric disturbance (MSTID) crossing the solar terminator over the geomagnetic equator during the period of post‐sunset rise (PSSR) of the F layer.
