Tsuruga's air quality reflects the Fukui Prefecture Wakasa Bay Sea of Japan coastal position, with vehicle traffic on surrounding roads and the nuclear power operations — Tsuruga hosting Japan's first commercial nuclear reactors — and manufacturing corridor contributing local sources. Consistent Sea of Japan maritime breezes provide coastal ventilation, while the nuclear plants' essentially zero combustion emissions and the outstanding Wakasa Bay coastal exposure generally maintain Tsuruga at moderate conditions throughout most of the year.

When is air pollution at its worst in Tsuruga?
The biggest local contributors to pollution in Tsuruga are road traffic and manufacturing activity, particularly once onshore breezes fall calm. Onshore breezes usually help clear the air, but pollution can build up when winds are light. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Tsuruga 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.
