Simultaneous storm time equatorward and poleward large-scale TIDs on a global scale [PDF]

, 2016
We report on the first simultaneous observations of poleward and equatorward traveling ionospheric disturbances (TIDs) during the same geomagnetic storm period on a global scale.

An LSTM-Based Framework for Tsunami Detection Using Anomalous Traveling Ionospheric Disturbances from GNSS

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Tsunamis pose a serious threat to coastal communities, necessitating timely and effective early warning systems. This study proposes a novel prediction framework that detects anomalous traveling ionospheric disturbances (TIDs) using Global Navigation ...

Spectral investigation of traveling ionospheric disturbances: IONOLAB-FFT

, 2017
Ionosphere is an important layer of atmosphere which is under constant forcing from both below due to gravitational, geomagnetic and seismic activities, and above due to solar wind and galactic radiation. Spatio-temporal variability of ionosphere is made

Statistical study of traveling ionospheric disturbances over South Africa

, 2019
This thesis provides a statistical analysis of traveling ionospheric disturbances (TIDs) in South Africa. The velocities of the TIDs were determined from total electron content (TEC) maps using particle image velocimetry (PIV).

Automated geolocation of diverse impulsive events using total electron content measurements

Frontiers in Astronomy and Space Sciences
Natural impulsive events such as earthquakes, volcanic eruptions, and thunderstorms, as well as anthropogenic events such as rocket launches and atmospheric re-entries, can generate acoustic-gravity waves (AGWs) that propagate in the upper-atmosphere and
