Daiwanishi in Hyogo reflects the Hyogo Prefecture Osaka metropolitan northern corridor position, 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 Hyogo Prefecture metropolitan corridor readings throughout most of the year.

When is air pollution at its worst in Daiwanishi?
In Daiwanishi, road traffic, heavy industry such as steel, cement, or petrochemical processing, and light manufacturing 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. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Daiwanishi 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.
