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.

A review of atmospheric gravity waves and travelling ionospheric disturbances: 1982-1995 [PDF]
Annales Geophysicae, 1996 Recent investigations of atmospheric gravity waves (AGW) and travelling ionospheric disturbances (TID) in the Earth\'s thermosphere and ionosphere are reviewed. In the past decade, the generation of gravity waves at high latitudes and their subsequent

Remote Sensing, 2023 We demonstrate a simple method to estimate the direction of propagation of travelling ionospheric disturbances using in-situ electron density measurements in the topside ionosphere by exploiting the side-by-side flying configuration of Swarm A and C ...

Model of traveling ionospheric disturbances [PDF]
Journal of Space Weather and Space Climate, 2013 A multiscale semi-empirical model of traveling ionospheric disturbances (TIDs) is developed. The model is based on the following assumptions: (1) TIDs are generated by acoustic-gravity waves (AGWs) and propagate as pressure waves; (2) time intervals between adjacent extrema of atmospheric pressure oscillations in a disturbance source are constant; (3 ...

Tomographic imaging of a large-scale travelling ionospheric disturbance during the Halloween storm of 2003 [PDF]
Annales Geophysicae, 2020 The most intense ionospheric storm observed in recent times occurred between 29 and 31 October 2003. The disturbances to the high-latitude regions set off several large-scale travelling ionospheric disturbances (LSTIDs), wave-like perturbations in the ...

The shock-acoustic waves generated by earthquakes [PDF]
, 2000 We investigate the form and dynamics of shock-acoustic waves generated by earthquakes. We use the method for detecting and locating the sources of ionospheric impulsive disturbances, based on using data from a global network of receivers of the GPS ...

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 ...

Studies of medium scale travelling ionospheric disturbances using TIGER SuperDARN radar sea echo observations [PDF]
Annales Geophysicae, 2004 Seasonal and diurnal variations in the direction of propagation of medium-scale travelling ionospheric disturbances (MSTIDs) have been investigated by analyzing sea echo returns detected by the TIGER SuperDARN radar located in Tasmania (43.4° S, 147.
