Outline of Final Research Achievements |
New particle formation (NPF) is important process by increasing the number of cloud condensation nuclei (CCN) and changing properties of cloud. As the summit of Mt. Fuji is usually positioned in the free troposphere, we can measure the size distribution of aerosol particles in the free troposphere. The burst of the particles smaller than 20nm in diameter was observed 241 times during 10 summer seasons (278 days). These events were more observed at night (135) than in the daytime (106). These night events had not observed at the other mountain site, e.g., Jungfraujoch, Himaraya. Air masses from the continental had the highest probabilities to lead to a NPF event, while the lower probabilities of NPF events were found from the maritime. NPF events were strongly influenced by the concentrations of the precursor gas and the existing particles. CCN concentration was higher when the air mass came from the continental with larger particle size.
