Abstract
Solar and geomagnetic activity (space weather, SW) as well as such atmospheric events as severe storms and hurricanes and sudden stratospheric warmings (SSW) are the main drivers of ionospheric disturbances including ionospheric scintillations. Ionospheric irregularities can drastically affect the quality of the electromagnetic signal between equipment installed on the ground and satellites, e.g., signal of the Global Navigation Satellite System (GNSS). A study of such disturbances is increasingly essential for the development of our society since activities of the modern industry and science rely more and more on GNSS-based technologies. Some studies were performed to assess the recurrence and the amplitude of ionospheric irregularities at middle latitudes, still, no such studies were ever performed for Portugal. The aim of the student project is to study ionospheric scintillation events using scintillation indices (SI) obtained by Portuguese GNSS receivers in relation to space weather and atmospheric conditions (statistical data analysis).
