| Research Abstract |
About 10% of dust particles had internal mixing state of dust and bioaerosols on the basis of the field measurements made in the atmosphere at Taklamakan desert, and this observational fact suggested that atmospheric bioaerosols detected in KOSA episode were originally transported from dust source areas by westerly.
The measurements at NOTO peninsula showed clear increase in content of atmospheric bioaerosols during KOSA episode, and confirmed that bioaerosols were transported with KOSA particles in the atmosphere.
Bioaerosols have been detected in the dust layers in the snow layer which accumulated near the summit of Mt.Tateyama during winter, and also suggest the possible long range transport and global diffusion of bioaerosols from KOSA source regions.
