“…The third type of waveform appeared in a relatively far area, as shown in Figure 8 (distance greater than 1000 km). A typical N-type TEC disturbance with an amplitude of 0.07-0.6 TECU was also triggered by the Chelyabinsk meteorite blast event [12,[14][15][16]. Similar TEC disturbance characteristics also were found in earthquakes, rocket launches, nuclear explosions, and tsunamis [3][4][5][6][7].…”

“…The detected TID propagation velocities, periods and wavelengths conform to the characteristics of gravity waves propagation in the ionosphere, which belongs to MSTID [26,27]. A similar TID propagation velocity was excited by the Chelyabinsk meteorite blast event [12,14,28], and this type of TID was determined to be caused by a gravity wave triggered by the meteor explosion. This kind of low velocity TID propagation distance generally does not exceed 1500 km.…”

“…The close-range ionospheric disturbance caused by the meteor explosion was detected by analyzing the changes in total electron content (TEC) at the ARTU station and then was compared the data with the ionospheric disturbance caused by the nuclear explosion [12,13]. Ding et al (2016) used the GPS data from the Crustal Movement Observation Network of China and detected ionospheric disturbances with a propagation velocity of 410 m/s and located 2500-3000 km from the explosion point [14]. Yang et al used the Japanese regional GPS network near the meteor explosion point, with the US regional GPS network to observe the ionospheric disturbances caused by three meteor explosions at speeds of 362, 733 and 862 m/s, respectively [15].…”

The Bering Sea meteor explosion that occurred on 18 December 2018 provides a good opportunity to study the ionospheric disturbances caused by meteor explosions. Total electron content (TEC) is the core parameter of ionospheric analysis. TEC and its changes can be accurately estimated based on the Global Positioning System (GPS). TID is detected in time and frequency domain based on power spectrum and Butterworth filtering method. By analyzing the waveform, period, wavelength, propagation speed and space-time distribution of TID, the location of the TID source is determined, and the process of TID formation and propagation is understood. The TID caused by meteor explosions has significant anisotropy characteristic. Two types of TID were found. For the first type, the average horizontal propagation velocity is 250.22 ± 5.98 m/s, the wavelength is ~135–240 km, the average period is about 12 min, and the propagation distance is less than 1400 km. About 8 min after the meteor explosion, the first type of TID source formed and propagated radially at the velocity of 250.22 ± 5.98 m/s. For the second type, the propagation velocity is ~434.02 m/s. According to the waveform, period, wavelength and propagation velocity of the TID, it is diagnosed to be the midscale traveling ionospheric disturbances (MSTID). Based on the characteristics of TID, we infer that the TID is excited by the gravity waves generated by the meteor explosion, which is in accordance with the propagation law of gravity waves in the ionosphere. And it is estimated that the average velocity of the up-going gravity waves is about 464.58 m/s. A simple model was established to explain the formation and the propagation of this TID, and to verify the characteristics of the TID propagation caused by nuclear explosion, earthquake, tsunami, and Chelyabinsk meteorite blast. It is estimated that the position of the TID source is consistent with the meteor explosion point, which further indicates that the TID is caused by the meteor explosion and propagates radially.

“…Gravity waves-related CIDs were mainly observed to the south and north of the epicenter; acoustic waves-related CIDs were recorded for 1000 km in all directions from the epicenter; CIDs related to Rayleigh waves could be observed only to the east of the epicenter. This directivity of Rayleigh wave-related CIDs is strongly consistent with azimuthal characteristics of the ground vibrations Ding F et al (2016). used the GPS network in northwest China and central Asia to monitor traveling ionospheric disturbances (TIDs), which were possibly excited by the large meteorite blast over Chelyabinsk, Russia, on 15 February 2013.…”

After the release of the previous report to the Committee on Space Research (COSPAR) on progress achieved by Chinese scientists in ionospheric researches (Liu LB and Wan WX, 2016), in the recent two years (2016–2017) many interesting new investigations into various ionospheric related issues have been completed. In this report, about 100 publications are summarized. The topics highlighted are as follows: Ionospheric space weather, ionospheric dynamics, ionospheric climatology and modelling, ionospheric irregularity and scintillation, Global Navigation Satellite System (GNSS) related ionospheric issues and other techniques, and radio wave propagation in the ionosphere. An outstanding feature is that more and more observations from the Meridional Project supported the ionospheric investigations.

We used dense global navigation satellite system data from China to track the propagation of traveling ionospheric disturbances (TIDs) triggered by the 2022 January 15 Tonga volcanic eruption. We identified two TIDs originating from the eruption. One, which has been reported widely by a number of recent investigations, had a velocity of ∼361 m/s. However, another long‐distance propagating TID with a velocity of ∼264 m/s has not been widely discussed. The velocities of these TIDs coincide with previous simulation results of gravity‐wave L0 and L1 modes. We propose that these TIDs were caused by the L0 and L1 ducted modes of gravity waves excited by the volcanic eruption. However, the L1 mode is usually negligible due to its weak amplitude in comparison with that of the L0 mode. The enormous energy release resulted in a stronger amplitude of the L1 mode, which induced a detectable TID in the ionosphere.
