Itami's air quality reflects the Osaka-Kobe metropolitan area's Osaka Itami International Airport position, with the airport's concentrated aviation operations and vehicle traffic on surrounding roads generating elevated NOₓ and ultrafine particles alongside the surrounding dense residential character. Osaka Bay breezes provide limited maritime ventilation, while the aviation emissions represent the most distinctive local emission source and summer photochemical ozone from the Kinki metropolitan corridor is the primary warm-season concern throughout the year.

When is air pollution at its worst in Itami?
In Itami, vehicle traffic, airport and aviation operations, together with heavy industry such as steel, cement, or petrochemical processing are the main local sources, with conditions worsening when warm, sunny weather takes hold. Strong sunlight reacting with local emissions drives up ground-level ozone. Sea breezes typically keep conditions in check, except during still weather.
Are air quality levels in Itami 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.
