Aisai's air quality reflects the Aichi Prefecture Kiso River plain position adjacent to Nagoya's western corridor, with vehicle traffic on surrounding roads and the manufacturing, agricultural, and residential character contributing local sources. The flat Nobi Plain allows reasonable dispersal, while summer photochemical ozone from the vast Chukyo metropolitan corridor is the primary warm-season concern and Aisai generally maintains moderate Nagoya metropolitan western corridor readings throughout most of the year.

When is air pollution at its worst in Aisai?
Aisai usually sees its poorest air quality when traffic on the surrounding roads, steel, cement, and chemical production, as well as light manufacturing coincide with periods when summer heat and strong sunlight build up. Heat and sunlight combine with emissions to form ozone at ground level. Cooler temperatures for the rest of the year keep this in check.
Are air quality levels in Aisai based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
