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 ...

Spectral investigation of traveling ionospheric disturbances: IONOLAB-FFT

Geodesy and Geodynamics, 2017
Ionosphere is an important layer of atmosphere which is under constant forcing from both below due to gravitational, geomagnetic and seismic activities, and above due to solar wind and galactic radiation. Spatio-temporal variability of ionosphere is made

Topside signature of medium-scale traveling ionospheric disturbances [PDF]

Annales Geophysicae, 2014
Plasma blobs, localized plasma density enhancements that occur singularly or in periodic groups, have been observed by in situ sensors in the lower- and middle-latitude nighttime ionosphere.

Inferring neutral winds in the ionospheric transition region from atmospheric-gravity-wave traveling-ionospheric-disturbance (AGW-TID) observations with the EISCAT VHF radar and the Nordic Meteor Radar Cluster [PDF]

Annales Geophysicae, 2023
Atmospheric gravity waves and traveling ionospheric disturbances can be observed in the neutral atmosphere and the ionosphere at a wide range of spatial and temporal scales.

Parameters of traveling ionospheric disturbances: results from spaced oblique HF sounding

Вісник Харківського національногоуніверситету імені В.Н. Каразіна. Серія: Радіофізика та електроніка, 2022
Urgency. A characteristic feature of the ionospheric radio channel is that its parameters depend on season, local time, solar activity, geographic coordinates, the state of the sun, the state of atmospheric-space weather, etc. The state of the atmosphere

Ionospheric Tilt Measurements: Application to Traveling Ionospheric Disturbances Climatology Study [PDF]

Radio Science, 2020
AbstractIonospheric tilt is a concept used to characterize local horizontal electron density gradients in the ionosphere using a mirror reflection model. Experimental results are presented that illustrate the validity and accuracy of such approach. Analysis of the tilt measurements collected in 2012–2014 with a digisonde at Ebro observatory (40.8°N, 0 ...

Periodic oscillations of Doppler frequency excited by the traveling ionospheric disturbances associated with the Tonga eruption in 2022

Earth, Planets and Space, 2023
The explosive eruption of the Hunga Tonga-Hunga Ha’apai volcano on 15 January 2022 generated atmospheric waves traveling around the Earth, which caused ionospheric disturbances on various spatio-temporal scales.

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.

Electromagnetic conjugacy of ionospheric disturbances after the 2022 Hunga Tonga-Hunga Ha’apai volcanic eruption as seen in GNSS-TEC and SuperDARN Hokkaido pair of radars observations

Earth, Planets and Space, 2022
To elucidate the characteristics of electromagnetic conjugacy of traveling ionospheric disturbances just after the 15 January 2022 Hunga Tonga-Hunga Ha’apai volcanic eruption, we analyze Global Navigation Satellite System-total electron content data and ...

Traveling Ionospheric Disturbances Characteristics during the 2018 Typhoon Maria from GPS Observations

Remote Sensing, 2020
Typhoons often occur and may cause huge loss of life and damage of infrastructures, but they are still difficult to precisely monitor and predict by traditional in-situ measurements.
