Outline of Final Research Achievements

In this research project, we have performed an intense observation of ionospheric and atmospheric composition by utilizing a frequency tunable lidar. Our data analysis of the obtained data, together with other composition data, have contributed to understanding of fine structures, vertical motions, auroral activity-related variations in the ionospheric and atmospheric composition. In addition, we have promoted development of new techniques and methods in the lidar system for future observations.
