Outline of Final Research Achievements

We aimed to elucidate the equatorial spread F phenomenon which is a strong instability phenomenon of the ionosphere, and the ionosphere structure. Specifically, (1) we studied statistical properties of ESF from long-term continuous observation with the equatorial atmosphere radar, (2) the time-space variation of ESF from the observation network developed in Southeast Asia and the ionosphere, and (3) tried further expansion of the satellite-beacon observation network and utilization of airglow observation from the International Space Station. This study project was successful as we published in total 26 articles in the peer-reviewed jounrnals.
