Magnetic storm effect on the occurrence of ionospheric irregularities at an equatorial station in the African sector

Annals of Geophysics, 2014
Large-scale ionospheric irregularities usually measured by GPS TEC fluctuation indices are regular occurrence at the equatorial region shortly after sunset around solar maximum. Magnetic storm can trigger or inhibit the generation of these irregularities

A Retrospective of Global Navigation Satellite System Ionospheric Irregularities Monitoring Networks in Brazil

Journal of Aerospace Technology and Management, 2023
The use of Global Navigation Satellite System (GNSS) for air and terrestrial navigation and for many applications is increasing in the last decades. However, the Earth’s ionosphere causes GNSS signal delay due to the total electron content (TEC) and ...

Diffusion spreading of middle-latitude ionospheric plasma irregularities [PDF]

Annales Geophysicae, 1995
In contrast to the way that the spreading of irregularities in a plasma is usually considered, the diffusion spreading of irregularities stretched along the geomagnetic field B is examined using a three-dimensional rigorous numerical model of quasi ...
