Storm Time Electrified MSTIDs Observed over Mid-Latitude North America

open access: yesJournal of Geophysical Research: Space Physics, 2022
Abstract 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. The mechanisms

A statistical analysis of medium-scale traveling ionospheric disturbances during 2014–2017 using the Hong Kong CORS network

open access: yesEarth, Planets and Space, 2019
We report a statistical study of medium-scale traveling ionospheric disturbances (MSTIDs) during 2014–2017 in the low-latitude China region using the Hong Kong Continuously Operating Reference Stations network with a baseline length of 10–15 km ...

Comparison of seasonal and longitudinal variation of daytime MSTID activity using GPS observation and GAIA simulations

open access: yesEarth, Planets and Space, 2021
The total electron content (TEC) data derived from the GAIA (Ground-to-topside model of Atmosphere Ionosphere for Aeronomy) is used to study the seasonal and longitudinal variation of occurrence of medium-scale traveling ionospheric disturbances (MSTIDs)

Multievent analysis of oscillatory motion of medium-scale traveling ionospheric disturbances observed by a 630-nm airglow imager over Tromsø [PDF]

open access: yes, 2020
We present a comprehensive investigation on the propagation characteristics of duskside medium‐scale traveling ionospheric disturbances (MSTIDs) using 630.0‐nm airglow emissions over Tromsø (69.6°N, 19.2°E; magnetic latitude: 66.7°N).

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

open access: yesPolar 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.

High-latitude MSTIDs over the EISCAT-3D site: solar activity and seasonal dependency [PDF]

open access: yesAnnales Geophysicae
This work involves an investigation of high-latitude medium scale traveling ionospheric disturbances (MSTIDs) over the newly established EISCAT-3D radar site. We have used the ground backscatter data from an HF radar located at Hankasalmi, Finland (∼62.3°

On the origin of mesoscale TIDs at midlatitudes [PDF]

open access: yesAnnales Geophysicae, 2011
A recent breakthrough experiment by Ogawa et al. (2009) showed that Mesoscale Traveling Ionospheric Disturbances (MSTIDs), a common phenomenon at midlatitudes, originate in the auroral zone as gravity waves.

Topside signature of medium-scale traveling ionospheric disturbances [PDF]

open access: yesAnnales Geophysicae, 2014
Plasma blobs, localized plasma density enhancements that occur singularly or in periodic groups, have been observed by in situ sensors in the lower- and middle-latitude nighttime ionosphere.

New aspects of the upper atmospheric disturbances caused by the explosive eruption of the 2022 Hunga Tonga–Hunga Ha’apai volcano

open access: yesEarth, Planets and Space, 2023
The Hunga Tonga–Hunga Ha’apai (HTHH) undersea volcanic eruption that occurred at 04:15 UT on 15 January 2022 is one of the most explosive events in the modern era, and a vertical plume reached approximately 55 km, corresponding to a height of the lower ...

Observations of conjugate MSTIDs using networks of GPS receivers in the American sector [PDF]

open access: yesRadio Science, 2016
AbstractThis study has used total electron content (TEC) values from an extended network of GPS receivers and a highly developed processing to characterize the conjugacy of medium‐scale traveling ionospheric disturbances (MSTIDs) over the American continent.
