Sakaidechō in Kagawa reflects the Kagawa Prefecture Seto Inland Sea and Honshi Bridge coastal position, with vehicle traffic on surrounding roads and the salt, vinegar, and manufacturing corridor contributing local sources. Consistent Seto Inland Sea maritime breezes provide coastal ventilation, while the outstanding coastal exposure generally maintains Sakaidechi at moderate to good Kagawa coastal readings throughout most of the year.

When is air pollution at its worst in Sakaidechō?
Sakaidechō usually sees its poorest air quality when road traffic together with manufacturing and food processing coincide with periods when maritime winds die down. 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 Sakaidechō 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.
