Kawashiri in Osaka reflects the Osaka metropolitan area's suburban position in the Higashiosaka 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 maintain moderate Osaka metropolitan suburban readings throughout most of the year.

When is air pollution at its worst in Kawashiri?

In Kawashiri, traffic emissions, heavy industrial and chemical processing, together with light manufacturing are the main local sources, with conditions worsening when summer heat and strong sunlight build up. 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 Kawashiri 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.
