Traveling Ionospheric Disturbances [PDF]

The Journal of the Acoustical Society of America, 1972
The T.I.D. of 13 May 1964, discussed by Theme appears to have had unusually high amplitude and would seem well suited for further investigation into its possible extension into the southern hemisphere as well as the possible presence of a simultaneous northbound wave.

Heating of the auroral ionosphere by traveling ionospheric disturbances initiated by atmospheric gravity waves

Annals of Geophysics, 2010
In the presence of perturbations of the thermospheric auroral region produced by traveling ionospheric disturbances during the propagation of atmospheric gravity waves, an analytical expression of the velocity of the thermospheric plasma is derived ...

Traveling Ionospheric Disturbances at Mars

Geophysical Research Letters, 2019
AbstractWe report the first extraterrestrial observation of traveling ionospheric disturbances (TIDs) in the ionosphere of Mars (below ≈160 km) by NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft. TIDs are ionospheric waves manifesting as an oscillation in density, velocity, and composition of ionospheric plasma.

Magnetic Field Signatures of Tropospheric and Thermospheric Lamb Modes Triggered by the 15 January 2022 Tonga Volcanic Eruption

Geophysical Research Letters, 2023
Intense eruptions of the Tonga volcano activated prominent traveling atmospheric disturbances (TADs) at 04:05UT on 15 January 2022. Himawari‐8 satellite images depict that TADs of the tropospheric Lamb wavefront propagate with a speed of 315 m/s and ...

Traveling Ionospheric Disturbances and Ionospheric Perturbations Associated With Solar Flares in September 2017 [PDF]

Journal of Geophysical Research: Space Physics, 2019
AbstractSolar flares provide strong impulsive radiation and energy injection to the sunlit upper atmosphere. The impact on the ionosphere is immense in spatial scale, and therefore, it is not immediately evident if dramatically elevated neutral heating can lead to excitation of acoustic gravity waves.

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).

Global Ionospheric Disturbance Propagation and Vertical Ionospheric Oscillation Triggered by the 2022 Tonga Volcanic Eruption

Atmosphere, 2022
The Tonga volcano erupted on 15 January 2022, at 04:15:45 UTC, which significantly influenced the atmosphere and space environment, at the same time, an unprecedented opportunity to monitor ionospheric anomalies is provided by its powerful eruption.
