Daitōchō in Osaka reflects the Osaka metropolitan area's eastern Higashi Osaka corridor, with vehicle traffic on surrounding roads and the manufacturing and residential character contributing local sources. Osaka Bay breezes provide limited maritime ventilation, while the broader Kinki metropolitan regional background and summer photochemical ozone from the vast metropolitan corridor maintain moderate Osaka eastern metropolitan suburban readings throughout most of the year.

When is air pollution at its worst in Daitōchō?
Daitōchō usually sees its poorest air quality when traffic emissions, petrochemical and refining operations, along with textile and manufacturing operations coincide with periods when hot, still weather settles in. Heat and sunlight combine with emissions to form ozone at ground level. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Daitōchō 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.
