Studies of medium scale travelling ionospheric disturbances using TIGER SuperDARN radar sea echo observations [PDF]
Annales Geophysicae, 2004 Seasonal and diurnal variations in the direction of propagation of medium-scale travelling ionospheric disturbances (MSTIDs) have been investigated by analyzing sea echo returns detected by the TIGER SuperDARN radar located in Tasmania (43.4° S, 147.

MHD nature of night‐time MSTIDs excited by the solar terminator
Geophysical Research Letters, 2009 We have obtained first experimental evidence in favour of the magnetohydrodynamic (MHD) nature of night‐time medium‐scale travelling ionospheric disturbances (MSTIDs). We used total electron content (TEC) measurement data from the dense GPS networks in California and in Japan for 2008–2009.

Space Weather, Volume 24, Issue 4, April 2026.Abstract The total solar eclipse on 8 April 2024 provided a unique opportunity to investigate the three‐dimensional (3‐D) ionospheric response under enhanced solar activity over North America. In this study, we processed high‐density GNSS observations from ∼1,700 stations to derive vertical total electron content and applied a multi‐term sinusoidal ...

Climatology of Plasma Irregularities Using ROTI Index From 2008 to 2023 in East West Asia
Space Weather, Volume 24, Issue 4, April 2026.Abstract This study investigates characteristics of ionospheric irregularities over the East–West Asian equatorial region using the Rate of TEC Index (ROTI) derived from Global Navigation Satellite System (GNSS) measurements. Data from four stations (GUAM, PIMO, CUSV, and IISC) were analyzed for 2008–2023, covering solar cycle (SC) 24 and the ascending

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract Extreme conditions during storms profoundly alter the evolution of equatorial plasma bubbles (EPBs), yet the key dynamics remains poorly understood. We document the rapid expansion, contraction, and decay of super EPBs in South America during the 12 November 2025 storm with Interplanetary Magnetic Field (IMF) Bz/By magnitude exceeding ∼50 nT ...

First LiDAR Observation of Quasi‐Periodic Structures in Mid‐Latitude E‐Region Meteoric Ca+ Layers
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract We report the first LiDAR observations of continuous quasi‐periodic (QP) metal density structures in mid‐latitude E‐region meteoric Ca+ layers using an all‐solid‐state LiDAR system in Beijing (40.4°N, 116.0°E). These QP Ca+ structures, with periods of 2–30 min and vertical wavelengths of ∼2–15 km, were primarily observed above 100 km.

C/NOFS observations of electromagnetic coupling between magnetically conjugate MSTID structures [PDF]
Journal of Geophysical Research: Space Physics, 2016 AbstractThis report demonstrates empirically that couplings between magnetically conjugate medium‐scale traveling ionospheric disturbances (MSTIDs) are electromagnetic in nature. This is accomplished by comparing plasma density, electric, and magnetic perturbations sampled simultaneously by sensors on the Communication/Navigation Outage Forecasting ...
