Kudamatsu's air quality reflects the Yamaguchi Prefecture Seto Inland Sea coastal position adjacent to the Tokuyama industrial corridor, with vehicle traffic on surrounding roads and the chemical, manufacturing, and port corridor generating elevated industrial emissions. Consistent Seto Inland Sea maritime breezes provide coastal ventilation, while the chemical industrial regional background represents the most notable local air quality influence and Kudamatsu generally maintains moderate Yamaguchi Seto Inland Sea corridor readings throughout most of the year.

When is air pollution at its worst in Kudamatsu?
In Kudamatsu, road traffic, heavy industry such as steel, cement, or petrochemical processing, and textile and manufacturing operations are the main local sources, with conditions worsening when dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Kudamatsu 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.
