Multitaper analysis of an MSTID event above Antarctica on 17 March 2013

Multitaper analysis of an MSTID event above Antarctica on 17 March 2013
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.

A Case Study on the Interaction Between MSTIDs' Fronts, Their Dissipation, and a Curious Case of MSTID's Rotation Over Geomagnetic Low‐Mid Latitude Transition Region

Journal of Geophysical Research: Space Physics, 2022
AbstractThis paper reports a rare interaction between two fronts of nighttime medium scale traveling ionospheric disturbances (MSTIDs) and associated phenomena observed over geomagnetic low‐mid latitude transition region on a geomagnetically quiet night (Ap = 5) of 21 May 2020.

MSTID extraction from more frequent ionograms

2017 XXXIInd General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2017
The paper shows the possibility of rapid extraction from more frequent ionograms not only strong medium-scale traveling ionospheric disturbances (MSTIDs) in the F region in the form of cusps and hooks, but also weak MSTIDs, whose form may differ from the cusp (hook) shaped. To isolate these MSTIDs will be enough to follow the slope of the F layer cusp (

Study of medium-scale traveling ionospheric disturbances (MSTID) with sounding rockets and ground observations

2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014
Medium-scale traveling ionospheric disturbance (MSTID) is an interesting phenomenon in the F-region. The MSTID is frequent in summer nighttime over Japan, showing wave structures with wavelengths of 100–200 km, periodicity of about 1 hour, and propagation toward the southwest.

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

Features of observing for weak MSTIDs by GNSS satellites

2019 URSI Asia-Pacific Radio Science Conference (AP-RASC), 2019
© 2019 URSI. All rights reserved. To analyze the weak midlatitude medium-scale travelling ionospheric disturbances we use the sufficiently dense network of GNSS receivers (more than 150 ground-based stations). We show the reason that the monitoring for MSTIDs by GNSS satellites is fragmented.
