| Outline of Final Research Achievements |
It is expected that the existence of ice nucleating particles (INPs) in the atmosphere has a significant impact on ice nucleation in clouds. However, because of cost issues and technical difficulties, the information on atmospheric INPs has been lacking. Here, we have tried to develop a new cold-stage-based droplet freezing technique. As a result, we could establish a new experimental system capable of measuring ice nucleating particles over a wide temperature range (about -30°C to 0°C).
