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 ...

Understanding Inter-Hemispheric Traveling Ionospheric Disturbances and Their Mechanisms

Remote Sensing, 2020
Traveling ionospheric disturbances (TIDs) are wave-like disturbances in ionospheric plasma density. They are often observed during both quiet (medium-scale TID) and geomagnetically disturbed (large-scale TID) conditions. Their amplitudes can reach double-

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 ...

Ionospheric effects of the solar flares of September 23, 1998 and July 29, 1999 as deduced from global GPS network data [PDF]

, 2000
This paper presents data from first GPS measurements of global response of the ionosphere to solar flares of September 23, 1998 and July 29, 1999. The analysis used novel technology of a global detection of ionospheric effects from solar flares (GLOBDET)

A LOFAR observation of ionospheric scintillation from two simultaneous travelling ionospheric disturbances [PDF]

Journal of Space Weather and Space Climate, 2020
This paper presents the results from one of the first observations of ionospheric scintillation taken using the Low-Frequency Array (LOFAR). The observation was of the strong natural radio source Cassiopeia A, taken overnight on 18–19 August 2013, and exhibited moderately strong scattering effects in dynamic spectra of intensity received across an ...

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 ...

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.

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).
