Polarization-resolved scintillations in Young's experiment
, 2022 The conventional scintillation, or intensity fluctuation, that occurs in random electromagnetic beams is just one member of a broader class of four interconnected, polarization-resolved scintillations.

Characteristics of VHF radiowave scintillations over a solar cycle (1983−1993) at a low-latitude station: Waltair (17.7°N, 83.3°E) [PDF]
Annales Geophysicae, 1997 The characteristics of VHF radiowave scintillations at 244 MHz (FLEETSAT) during a complete solar cycle (1983–93) at a low-latitude station, Waltair (17.7°N, 83.3°E), are presented.

VARIABLE RADIO SOURCES AND TAKING INTO ACCOUNT OF IONOSPHERIC EFFECTS
Odessa Astronomical Publications, 2017 Histograms and mean value of scintillations indexes are obtained for power cosmic radio sources on observations during 1998-2001. Using simulations it is showed that scintillations with periods more then 10 minutes give the error of measuring of ...

Simultaneous observations of ESF irregularities over Indian region using radar and GPS [PDF]
Annales Geophysicae, 2008 In this paper, we present simultaneous observations of temporal and spatial variability of total electron content (TEC) and GPS amplitude scintillations on L1 frequency (1.575 GHz) during the time of equatorial spread F (ESF) while the MST radar (53 ...

SPACE WEATHER: RISK FACTORS FOR GLOBAL NAVIGATION SATELLITE SYSTEMS
Solar-Terrestrial Physics, 2021 Extreme space weather events affect the stability and quality of the global navigation satellite systems (GNSS) of the second generation (GPS, GLONASS, Galileo, BeiDou/Compass) and GNSS augmentation.

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‐

A Case Study of Polar Cap Sporadic-E Layer Associated with TEC Variations
Remote Sensing, 2021 The Sporadic-E (Es) layer is an often-observed phenomenon at high latitudes; however, our understanding of the polar cap Es layer is severely limited due to the scarce number of measurements.
