A comparison between large‐scale irregularities and scintillations in the polar ionosphere
Geophysical Research Letters, 2016 A comparison tool has been developed by mapping the global GPS total electron content (TEC) and large coverage of ionospheric scintillations together on the geomagnetic latitude/magnetic local time coordinates. Using this tool, a comparison between large‐

Equatorial scintillations in relation to the development of ionization anomaly [PDF]
Annales Geophysicae, 2006 The irregularities in the electron density distribution of the ionosphere over the equatorial region frequently disrupt space-based communication and navigation links by causing severe amplitude and phase scintillations of signals.

Latitudinal extension of low-latitude scintillations measured with a network of GPS receivers [PDF]
Annales Geophysicae, 2004 A latitudinal-distributed network of GPS receivers has been operating within Colombia, Peru and Chile with sufficient latitudinal span to measure the absolute total electron content (TEC) at both crests of the equatorial anomaly.

The role of post-sunset vertical drifts at the equator in predicting the onset of VHF scintillations during high and low sunspot activity years [PDF]
Annales Geophysicae, 2006 The day-to-day variability in the occurrence of ionospheric scintillations, which are of serious concern in the trans-ionospheric communications, makes their prediction still a challenging problem.

An Increase of GNSS Data Time Rate and Analysis of the Carrier Phase Spectrum
Remote Sensing, 2023 Natural hazards and geomagnetic disturbances can generate a combination of atmospheric and ionospheric waves of different scales. The carrier phase of signals of global navigation satellite system (GNSS) can provide the highest efficiency to detect and ...

Remote Sensing, 2021 Irregularities in electron density usually correlate with ionospheric plasma perturbations. These variations causing radio signal fluctuations, in response, generate ionospheric scintillations that frequently occur in low-latitude regions.

Geodesy and Geodynamics, 2019 The amplitude and phase of L-band satellite signals are fluctuated randomly due to small scale electron density irregularity structures in the ionosphere which result in fleeting variations, known as ‘ionospheric scintillations’.
