Mitoyo's air quality benefits from its exceptional Kagawa Prefecture Seto Inland Sea and Sanuki coastal position, with consistent Seto Inland Sea maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the fishing, agriculture, and manufacturing corridor contribute local sources, while the outstanding coastal exposure generally maintains Mitoyo among Kagawa Prefecture's more moderately ventilated coastal cities throughout most of the year.

When is air pollution at its worst in Mitoyo?
In Mitoyo, traffic on the surrounding roads, manufacturing and food processing, together with farming and agricultural processing are the main local sources, with conditions worsening when onshore breezes fall calm. Sea breezes typically keep conditions in check, except during still weather. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Mitoyo 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.
