Choice of optimum heights for registration of ionospheric response onto earthquakes
E3S Web of Conferences, 2017 To investigate the dependence of ionospheric disturbances on height we used model calculations, and the data of seismic and ionospheric observations during the Tohoku-Oki earthquake.

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

Simulation of Focusing Effect of Traveling Ionospheric Disturbances on Meter-Decameter Solar Dynamic Spectra [PDF]
, 2018 For the first time we present simulation results of the focusing effect of the ionospheric plasma density irregularities, namely, Medium Scale Traveling Ionospheric Disturbances (MSTIDs), on solar radio emission by applying a ray-tracing method to the ...

Ionospheric Phase Compensation for InSAR Measurements Based on the Faraday Rotation Inversion Method
Sensors, 2020 The ionospheric error can significantly affect the synthetic aperture radar (SAR) signals, particularly in the case of L band and lower frequency SAR systems. The ionospheric distortions are mixed with terrain and ground deformation signals, lowering the

The GPS global detection of the ionospheric response to solar flares [PDF]
, 2000 This author suggests the concept of a new technology for global detection (GLOBDET) of atmospheric disturbances of natural and technogenic origin, on the basis of phase measurements of the total electron content (TEC) in the ionosphere using an ...

Feasibility of precise navigation in high and low latitude regions under scintillation conditions [PDF]
, 2018 Scintillation is one of the most challenging problems in Global Navigation Satellite Systems (GNSS) navigation. This phenomenon appears when the radio signal passes through ionospheric irregularities.

SUDDEN DISTURBANCES OF THE IONOSPHERE
Journal of Applied Physics, 1937 The phenomenon described in this paper is the occurrence of a very sudden change in ionization of a portion of the ionosphere. It manifests itself by the complete fading out of high-frequency radio transmission for a period of a few minutes to an hour or more, and by perturbations of terrestrial magnetism and earth currents.

Critical issues in ionospheric data quality and implications for scientific studies [PDF]
, 2019 Ionospheric data are valuable records of the behavior of the ionosphere, solar activity, and the entire Sun-Earth system. The data are critical for both societally important services and scientific investigations of upper atmospheric variability.
