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.

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).

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 ...

Interaction Between Nighttime MSTID and Mid-Latitude Field-Aligned Plasma Depletion Structure Over the Transition Region of Geomagnetic Low-Mid Latitude: First Results From Hanle, India

Journal of Atmospheric and Solar-Terrestrial Physics, 2021
In this paper, we study the interaction between a nighttime Medium Scale Traveling Ionospheric Disturbance (MSTID) and geomagnetic north-south oriented field-aligned plasma depletion structure over Hanle, Leh Ladakh (32.7°N, 78.9°E; Mlat. ~24.1°N), India

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

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 ...
