My major research interests are development of remote sensing observation systems for atmospheric phenomena and the utilization of observational data. Remote sensing using electromagnetic waves (light or radio waves) is a technology that transmits and receives (or only receives) electromagnetic waves to obtain physical quantities at a distance. For example, weather radar is one type of remote sensing techniques, and by transmitting and receiving radio waves, we can know precipitations at a distance. I have been involved in the development and observation of three remote sensing observation systems: lightning sensors, weather radars, and atmospheric lidars. Using these observation systems, I have been engaged in the analysis of phenomena that have not yet been proven theoretically. In recent years, I have also started to assimilate observational data to improve forecasting accuracy of local heavy precipitation.
