Conclusions
•Interval recording method by photo and video cameras, in
conjunction with satellite imagery and other related data, is
confirmed to be useful.
•RGB analysis applied to interval records is effective to study
the turbidity of the air. (See URL below.)
•Aerosol Vapor Index images of MTSAT1R are helpful in
detecting Asian dust, as before.
• Quicklook photo-albums at UB, Changchun and
Kagoshima in 2006 and satellite images are shown in
a homepage of Asian Dust in 2006 :
