Abstract
We continuously measured cloud condensation nuclei (CCN) concentration (NCCN) with six different supersaturation conditions (SS=0.10, 0.17, 0.24, 0.31, 0.38, 0.44%) at the summit of Mt. Fuji from July. 17 to Aug. 25, 2010. Using backward trajectory analysis (NOAA HYSPLIT MODEL), types of air masses were classified according to the region and altitude. It was expected that the summit of Mt. Fuji was located in the free troposphere when the air masses came from a higher altitude than that of Mt. Fuji (3776 m a.s.l.). When the summit of Mt. Fuji was located in the free troposphere, NCCN was lower by 20%~50% than that under the other condition. However, continental air masses that came from China had a larger NCCN. The continental air masses at the summit of Mt. Fuji and other areas were similar in the shape of CCN spectra. We speculated that CCN concentration may be influenced by the long-range transport of pollution from the continent when the summit of Mt. Fuji is located in the free troposphere.<br>
