“…Having derived these parameters, it was possible to establish a statistical regional picture of the TID occurrence and their typical characteristics. It is worth noting that the results of this study significantly extend those obtained in the earlier work by Sopin et al []. Specifically, in this work detailed patterns of TID propagation direction are presented as functions of the local time and geomagnetic activity, which was not reported before.…”

“…Some results of the ionospheric disturbance propagation direction were reported in literature based on other types of measurements in middle and high latitudes [ He et al , ; Galushko et al , ; Crowley et al , ]. For example, the rotation of the TID propagation direction throughout the day was reported by Crowley et al [] based on their measurements in Antarctic Peninsula using HF radar, and a similar effect was mentioned by other authors [ He et al , ; Sopin et al , ; Fedorenko and Kryuchkov , ]. For example, He et al [] reported that in their observations the MSTIDs propagated mostly to NW during the day; however, at around 09 LT the propagation direction changed to NE, and in the afternoon (~15 LT) TIDs again propagated to the north or NW.…”

“…That is why some authors ignore their motion, assuming V > > V p . For example, Sopin et al [] analyzed only the cases of relatively small time delays τ ij max , whose values correspond to V ≥100…150 m/s with some reservations. This is a possible reason for observing somewhat overestimated values of the mean propagation velocities of the medium‐scale ionospheric disturbances that were reported.…”

“…That made it possible to study ionospheric irregularities in the Antarctic region with multipositional GNSS observations. For example, Sopin et al [] used cross‐correlation analysis to determine directions and propagation velocities of medium‐scale (MS) ionospheric disturbances using the TEC records from these three stations collected from April 2009 to June 2010 (450 days of observations). This database made it possible to establish the daily trends of the disturbance parameters and to determine their characteristic features.…”

Results of ionospheric disturbances observations using multisite total electron content (TEC) measurements over the Antarctic Peninsula for the period from 2009 to 2012 are presented. Diurnal dependencies of the disturbance occurrence frequency, velocity, and direction of motion are established. Parameters of the disturbances are calculated using dynamic approach to the problem of ionospheric disturbances diagnostics which has been extended to allow for an arbitrary waveform of TEC perturbations. Specific data quality constraints are introduced to determine the presence of wavelike disturbances in the TEC records and to satisfy the required accuracy of parameter reconstruction. Statistical treatment of the results shows that during the daytime disturbances propagate predominantly in the northern and northeastern directions. In the evening and nocturnal hours the northwestern direction is prevailing, with the characteristic disturbance velocities ranging from 10 to 250 m/s. The most probable velocities are tens of meters per second, while the mean values are equal to about 100–130 m/s. In the daytime the velocities of the ionospheric disturbances are even higher. During the Antarctic winter time disturbances are usually observed at local noon time, in sharp contrast with the summer time, when they are present during the nights and mornings.

“…At the same time, the spatial resolution for most practical implementations of regional TEC maps is the same as for the global ones [ 2 , 3 , 4 , 7 ]. Investigations of TEC variations associated with powerful processes in the atmosphere [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ] were done by using the data of vast continental-scale networks of GNSS receivers. Results for the visualization of processes that occurred in the near Earth space were given for groups of ionospheric pierce points only.…”

The technique of the orthogonal projection of ionosphere electronic content variations for mapping total electron content (TEC) allows us to visualize ionospheric irregularities. For the reconstruction of global ionospheric characteristics, numerous global navigation satellite system (GNSS) receivers located in different regions of the Earth are used as sensors. We used dense GNSS networks in central Europe to detect and investigate a special type of plasma inhomogeneities, called travelling ionospheric disturbances (TID). Such use of GNSS sensors allows us to reconstruct the main TID parameters, such as spatial dimensions, velocities, and directions of their movement. The paper gives examples of the restoration of dynamic characteristics of ionospheric irregularities for quiet and disturbed geophysical conditions. Special attention is paid to the dynamics of ionospheric disturbances stimulated by the magnetic storms of two St. Patrick’s Days (17 March 2013 and 2015). Additional opportunities for the remote sensing of the ionosphere with the use of dense regional networks of GNSS receiving sensors have been noted too.
