Numazu's air quality reflects the Shizuoka Prefecture Suruga Bay coastal position with Mount Fuji's iconic backdrop, with consistent Pacific and Suruga Bay maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the manufacturing, fishing, and tourism corridor contribute local sources, while the outstanding coastal exposure and the extraordinary Fuji and Hakone highland backdrop create dramatic topographic variation and Numazu generally maintains moderate to good conditions for a major Japanese Pacific coastal city throughout most of the year.

When is air pollution at its worst in Numazu?

Air quality in Numazu tends to be worse when road traffic, textile and manufacturing operations, together with shipbuilding and port operations build up and the sea breeze weakens. 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 Numazu 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.
