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 ...

On the Results of a Special Experiment on the Registration of Traveling Ionospheric Disturbances by a System of Synchronously Operating Chirp Ionosondes

Atmosphere, 2022
We present the results of observations of traveling ionospheric disturbances (TIDs) based on the data of the operation of the network of chirp oblique sounding stations of the ionosphere on 18–19 December 2019. For observations, four stations of the same

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).

Observations of ionospheric disturbances via U-shaped traces on ionograms

Геодинамика и тектонофизика, 2019
The ionospheric vertical sounding is a basic technique for studying the Earth’s ionosphere. Taking into account the fact that conditions for propagation of radio waves depend on the operating frequency, diagnostics of the ionosphere is performed using ...

Daytime Equatorial Spread F‐Like Irregularities Detected by HF Doppler Receiver and Digisonde

Space Weather, 2021
Daytime equatorial spread F (ESF) is not as common as nighttime ESF due to the presence of a highly conducting E‐layer during the daytime which counteracts the development of F‐layer plasma irregularities.

Medium-scale traveling ionospheric disturbances created by primary gravity waves generated by a winter storm

Journal of Space Weather and Space Climate
This study explores the meteorological source and vertical propagation of gravity waves (GWs) that drive daytime traveling ionospheric disturbances (TIDs), using the specified dynamics version of the SD-WACCM-X (Whole Atmosphere Community Climate Model ...
