Pilot Ionosonde Network for Identification of Traveling Ionospheric Disturbances

Radio Science, 2018
AbstractTraveling ionospheric disturbances (TIDs) are the ionospheric signatures of atmospheric gravity waves. Their identification and tracking is important because the TIDs affect all services that rely on predictable ionospheric radio wave propagation.

Determination of travelling ionospheric disturbances

Journal of Atmospheric and Terrestrial Physics, 1978
A total of 35 days of Faraday rotation data was obtained from the ATS-6 radio beacon experiment operating with the closely spaced network of Elbert, Table Mountain, and Fort Morgan. The 140-MHz Faraday bandpass data are uncorrelated in the transmission range from 8 to 45 minutes. There are distinct, well correlated, and time-displaced maxima and minima

The dispersion of traveling ionospheric disturbances

Journal of Geophysical Research: Space Physics, 1983
The horizontal dispersion of relatively large daytime TID events seen by the Dartmouth rapid‐run ionosonde network is found to conform, at least qualitatively, to that predicted by previous theoretical treatments of freely propagating gravity waves in the presence of dissipation.

Traveling disturbances originating in the outer ionosphere

Journal of Geophysical Research, 1959
Some observations that have been obtained with variations of the classical echo-sounding method must be interpreted as resulting from perturbation and/or oscillation phenomena occurring in the outer ionosphere. The vertical velocity component of ‘traveling disturbances’ coming from outside and propagating through the ionosphere is determined as 115±35 ...

Travelling Disturbances in the Ionosphere

Nature, 1953
MEASUREMENTS of the horizontal velocity of travelling disturbances in the F2 region of the ionosphere have been made in this department over the past three years, using the method described by Munro1. Constant-frequency pulse transmitters were set up at the base station in the Physics Department of the University of Western Australia, and at two other ...
