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.

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.

Estimation of the parameters of traveling ionospheric disturbances using a chirp-ionosondes network

Учёные записки Казанского университета: Серия Физико-математические науки, 2022
In this article, the results of our observations of traveling ionospheric disturbances are discussed using the data from a network of chirp stations for oblique ionospheric sounding in December 2019. All observations were made with the same type of chirp

Identification of Large-Scale Travelling Ionospheric Disturbances (LSTIDs) Based on Digisonde Observations

Atmosphere, 2023
In this paper we analyze Digisonde observations obtained in the European region to specify the effects of large-scale travelling ionospheric disturbances (LSTIDs) on the ionospheric characteristics that define the conditions in the bottomside ionosphere.

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 ...
