Abstract:
Magnetically conjugate all-sky imagers (ASIs) from low to sub-auroral latitudes are used to investigate inter-hemispheric coupling of ionospheric processes including medium scale travelling ionospheric disturbances (MSTIDs) and, at higher latitudes, stable auroral red (SAR) arcs. The chain of imagers operated by Boston University in the American sector provide thermosphere/ionosphere information through the observation of brightness patterns in 630.0 nm airglow simultaneously at both hemispheres. Complementary information was obtained from space-based satellite data (C/NOFS, DMSP, GPS and RBSP). This study aims to present a comprehensive analysis of thermosphere/ionosphere processes and their coupling mechanisms covering L-shell values from ~ 1.1 to ~3.
