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

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 ...

Modeling Equatorial Plasma Depletion and Anisotropic MSTIDs from the April 2024 Eclipse

International Journal of Astrophysics and Space Science
Background: Total solar eclipses provide unique opportunities to study the ionospheric response to sudden solar extreme ultraviolet (EUV) reduction. The April 8, 2024 total solar eclipse occurred near the peak of Solar Cycle 25, offering a rare chance to examine eclipse-driven plasma depletion and traveling ...

Statistical Study of Seasonal and Solar Activity Dependence of Nighttime MSTIDs Occurrence Using the SuperDARN Hokkaido Pair of Radars [PDF]

, 2022
We conduct a statistical analysis on nighttime medium-scale traveling ionospheric disturbances (MSTIDs) using the Super Dual Auroral Radar Network (SuperDARN) Hokkaido East (43.53°N, 143.61°E) high-frequency (HF) radar data from 2009 to 2019 and the ...

MSTID forecasting methodology and data inventory

, 2023
T-FORS project aims at providing new models able to interpret a broad range of observations of the solar corona, the interplanetary medium, the magnetosphere, the ionosphere and the atmosphere, and to issue forecasts and warnings for TIDs several hours ahead.

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 ...

Tandem Observations of Nighttime Mid‐Latitude Topside Ionospheric Perturbations

Space Weather, 2023
Nighttime medium‐scale traveling ionospheric disturbances (MSTIDs) have been generally observed by ground‐based instruments. However, they provide 2‐dimensional images over only a limited field of view and are not distributed globally.

Storm Time Electrified MSTIDs Observed over Mid-Latitude North America

Journal of Geophysical Research: Space Physics, 2022
Medium-scale Traveling Ionospheric Disturbances (MSTIDs) are prominent and ubiquitous features of the mid-latitude ionosphere, and are observed in Super Dual Auroral Radar Network (SuperDARN) and high-resolution Global Navigational Satellite Service (GNSS) Total Electron Content (TEC) data.

Solar activity dependence of medium-scale traveling ionospheric disturbances using GPS receivers in Japan

Earth, Planets and Space, 2021
In order to reveal solar activity dependence of the medium-scale traveling ionospheric disturbances (MSTIDs) at midlatitudes, total electron content (TEC) data obtained from a Global Positioning System (GPS) receiver network in Japan during 22 years from
