Abstract:
High-latitude F region is a place where intense radio scintillation is produced by various types of electron density irregularities. The irregularities are known to be associated with plasma patches (enhancements of plasma density with respect to the background density), but the irregularities of other types also frequently occur. The distribution of different types of irregularities has not yet been clearly understood. In this study, we classify the irregularity types based on the morphology and investigate their distribution by analyzing the measurements of the electron density in 2014–2015 by the Langmuir probe onboard the Swarm satellites. We also process the GPS scintillation data provided by the Swarm mission to investigate the dependence of the scintillation occurrence and intensity on the irregularity type.
