Development of a System for Detecting Traveling Ionospheric Disturbances Based on GNSS Data
Atmosphere, 2022 The large amount of data that are available for ionospheric studies using the GPS TEC method, as well as the need to take into account complex atmospheric dynamics, create certain difficulties in automating the process of searching and recognizing ...

Traveling ionospheric disturbances triggered by the 2009 North Korean underground nuclear explosion [PDF]
Annales Geophysicae, 2015 Underground nuclear explosions (UNEs) can induce acoustic-gravity waves, which disturb the ionosphere and initiate traveling ionospheric disturbances (TIDs).

Vertical Characteristics of Travelling Ionospheric Disturbances [PDF]
Australian Journal of Physics, 1960 The vertical dimensions of travelling disturbance phenomena have been investigated by derivation of the associated true height distributions of ion density. The height at which they appear often has an upper limit which may fluctuate in height from day to day.

Traveling ionospheric disturbances detected in the FRONT Campaign [PDF]
Geophysical Research Letters, 2001 The F‐region Radio and Optical measurement of Nighttime TID (FRONT) campaign was conducted to clarify the non‐classical features of traveling ionospheric disturbances (TIDs) at mid‐latitudes in May, 1998 and August, 1999. A cluster of all‐sky CCD cameras and a GPS receiver network observed a wide area of the ionosphere over Japan to detect the spatial ...

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Microbursts are thought to be a key contributor to radiation belt electron loss, with chorus waves considered a primary driver of this precipitation. However, the conditions under which chorus waves produce MeV electron loss remain poorly constrained.

GPS observations of medium-scale traveling ionospheric disturbances over Europe [PDF]
Annales Geophysicae, 2013 Two-dimensional structures of medium-scale traveling ionospheric disturbances (MSTIDs) over Europe have been revealed, for the first time, by using maps of the total electron content (TEC) obtained from more than 800 GPS receivers of the European

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract This study investigates the roles of neutral winds, composition and atmospheric waves in storm‐time post‐midnight equatorial plasma bubble (EPB) development using the coupled SAMI3‐WACCMX model. Simulations reveal the formation of post‐midnight EPBs extending beyond 1,500 km in altitude and persisting into the post‐sunrise period.
