Monitoring of GNSS Scintillation Indices during the MOSAiC Expedition: Preliminary Results of Ship-borne and Station-based Observations in the Arctic
Polar regions are of particular interest to study the interaction of space weather (solar radiation and particle precipitation) with the Earth’s atmosphere and magnetosphere. We focus here on space-weather induced irregularities of electron density in the upper atmosphere and their impact on radio s...
