Severe L-band scintillation over low-to-mid latitudes caused by an extreme equatorial plasma bubble: joint observations from ground-based monitors and GOLD

Earth, Planets and Space, 2023
The occurrence of plasma irregularities and ionospheric scintillation over the Caribbean region have been reported in previous studies, but a better understanding of the source and conditions leading to these events is still needed.

Precursors Identification for Forecasting UHF‐Band Ionospheric Scintillation Events Over Chinese Low‐Latitude Region by Deep Learning

Earth and Space Science, 2022
The occurrences of the UHF‐band ionospheric scintillation events caused by Equatorial Plasma Bubbles (EPBs) in the low‐latitude region depend on many factors.

Ionospheric scintillation monitoring and modelling [PDF]

Annals of Geophysics, 2009
This paper presents a review of the ionospheric scintillation monitoring and modelling by the European groups involved in COST 296. Several of these groups have organized scintillation measurement campaigns at low and high latitudes. Some characteristic results obtained from the measured data are presented.

Analysis and Characterization of an Unclassified RFI Affecting Ionospheric Amplitude Scintillation Index Over the Mediterranean Area

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Radio frequency (RF) signals transmitted by Global Navigation Satellite Systems (GNSSs) are exploited as signals of opportunity in many scientific activities, ranging from sensing waterways and humidity of the terrain to the monitoring of the ionosphere.

GPS phase scintillation and proxy index at high latitudes during a moderate geomagnetic storm [PDF]

Annales Geophysicae, 2013
The amplitude and phase scintillation indices are customarily obtained by specialised GPS Ionospheric Scintillation and TEC Monitors (GISTMs) from L1 signal recorded at the rate of 50 Hz.

Mid-latitude ionospheric scintillation anomaly in the Far East [PDF]

Annales Geophysicae, 2003
A long-term (over 3 years) study has been undertaken to obtain a comprehensive evaluation of VHF ionospheric scintillation morphology in East Asia (at Kokobunji in Japan), using amplitude records from Transit satellites.

VARIATIONS OF IONOSPHERIC SCINTILLATION INDEX FOR THE SHORT-TIME INTERVALS OBSERVED ON THE POWER COSMIC RADIO SOURCES AT THE DECAMETER WAVELENGTHS

Radio Physics and Radio Astronomy, 2017
Purpose: Variations of ionospheric scintillation index of the power cosmic radio sources (3С144, 3С274, 3С405, and 3С461) observed for the year-to-day time intervals with the radio telescope at the decameter wavelengths are analyzed.

Survey on signal processing for GNSS under ionospheric scintillation: Detection, monitoring, and mitigation

Navigation, 2020
Ionospheric scintillation is the physical phenomena affecting radio waves coming from the space through the ionosphere. Such disturbance is caused by ionospheric electron‐density irregularities and is a major threat in Global Navigation Satellite Systems
