Toyooka's air quality reflects the Hyogo Prefecture Japan Sea Maruyama River coastal position adjacent to the Kinosaki Onsen hot spring resort, with vehicle traffic on surrounding roads and the hot spring tourism, stork conservation, and manufacturing corridor contributing local sources. Consistent Sea of Japan maritime breezes provide coastal ventilation, while the surrounding Maruyama valley highlands create topographic variation and Toyooka generally maintains good to moderate conditions for a Japanese Sea of Japan coastal resort city throughout most of the year.

When is air pollution at its worst in Toyooka?
Air quality in Toyooka tends to be worse when road traffic, textile and manufacturing operations, along with seasonal tourism traffic build up and maritime winds die down. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. This coastal advantage is less pronounced during still, high-pressure weather.
Are air quality levels in Toyooka 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.
