Hamada's air quality benefits from its exceptional Shimane Prefecture Sea of Japan coastal position, with consistent Sea of Japan maritime breezes providing reliable ventilation along the historic Hamada trading port. Vehicle traffic on surrounding roads and the fishing, traditional crafts, and manufacturing corridor contribute local sources, while the outstanding Sea of Japan coastal exposure and the Chugoku Mountains rising inland create topographic variation and Hamada generally maintains good to moderate conditions for a Japanese San'in coastal city throughout most of the year.

When is air pollution at its worst in Hamada?
Air quality in Hamada tends to be worse when traffic emissions, manufacturing activity, and shipbuilding and port operations build up and onshore breezes fall calm. Onshore breezes usually help clear the air, but pollution can build up when winds are light. Areas further inland without this ventilation tend to fare worse.
Are air quality levels in Hamada 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.
