Short summary
Air is as valuable a resource as water. We defined a novel index, the Clean aIr Index (CII), to evaluate air cleanliness in terms of a global standard. Japan was chosen as a study area. The air cleanliness of Tokyo was 1.5 and 2.3 times higher than that of Seoul and Beijing, respectively. Extremely clean air occurred to the west of the Pacific coast and in the southern remote islands of Tokyo during summer. CII can be valuable, e.g., for encouraging sightseeing in and migration to fresher air.
