Climatology of GPS phase scintillation at northern high latitudes for the period from 2008 to 2013 [PDF]

Annales Geophysicae, 2015
Global positioning system scintillation and total electron content (TEC) data have been collected by ten specialized GPS Ionospheric Scintillation and TEC Monitors (GISTMs) of the Canadian High Arctic Ionospheric Network (CHAIN).

Carbon Quantum Dot-Embedded SiO₂: PMMA Hybrid as a Blue-Emitting Plastic Scintillator for Cosmic Ray Detection

Photonics
This work reports the synthesis and characterization of Carbon Quantum Dots (CQDs) embedded in an organic–inorganic hybrid SiO2: PMMA matrix, designed as a novel plastic scintillator material. The CQDs were synthesized through a solvo-hydrothermal method

Scintillation in the Arctic during the May 2024 Mother’s Day storm

Journal of Space Weather and Space Climate
The geomagnetic storm that started on May 10th 2024, often referred to as the “Mother’s Day” or “Gannon” storm, was the strongest storm for decades,with polar lights visible across significant parts of the globe.

GOLD plasma bubble observations comparison with geolocation of plasma irregularities by back propagation of the high-rate FORMOSA7/COSMIC 2 scintillation data

Frontiers in Astronomy and Space Sciences
Using the high-rate phase and amplitude scintillation data from FORMOSA7/COSMIC two mission and back-propagation method, we geolocate plasma irregularities that cause scintillations.

The Behaviors of Ionospheric Scintillations Around Different Types of Nightside Auroral Boundaries Seen at the Chinese Yellow River Station, Svalbard

Frontiers in Astronomy and Space Sciences, 2018
Dynamical nightside auroral structures are often observed by the all sky imagers (ASI) at the Chinese Yellow River Station (CYRS) at Ny-Ålesund, Svalbard, located in the polar cap near poleward edge of the nightside auroral oval.

Spacecraft radio signal polarization calibration

Frontiers in Astronomy and Space Sciences
IntroductionThe only reliable method to remotely obtain magnetic field information across large swaths of interplanetary/interstellar plasma is with the measurement of Faraday rotation of polarized radio signals.MethodsFocusing on the high frequency ...

Interaction of plasma drifts: A hypothesis for equatorial spread F occurrence

Journal of Space Weather and Space Climate
Studies on the generation mechanisms of post-sunset ionospheric irregularities, which constitute a threat to trans-ionospheric radio propagation, particularly at the African sector, are quite sparse.

Amplitude scintillation detection with geodetic GNSS receivers leveraging machine learning decision tree

Satellite Navigation
The amplitude scintillation detection is typically achieved by using the scintillation index generated by dedicated and costly ionospheric scintillation monitoring receivers (ISMRs).
