Outline of Final Research Achievements

This study aimed to revel the effect of the tropospheric activities on the Mesosphere and the Thermosphere using the coordinated observation of ground-based imagers and ISS-IMAP/VISI (International Space Station - Ionosphere, Mesosphere upper Atmosphere, and Plasmasphere/ Visible-light and infrared spectrum imager) on the international space station. The calibration of ISS-IMAP/VISI by the comparison with simultaneous observation of the ground-based imager is another target of this study. An all-sky imager was installed on Hawaii Haleakala observatory of Tohoku University on March 2013, and the coordinated observation was carried out for about two and half years. The simultaneous observational data of the wave-like structures in the Mesosphere by the space-borne and the ground-based imaging was successfully obtained by this study. The characteristics of the atmospheric gravity waves that connect the Troposphere and the upper atmosphere were elucidated by this coordinated observation.
