Maizuru's air quality reflects the Kyoto Prefecture Sea of Japan Wakasa Bay coastal position, with vehicle traffic on surrounding roads and the Japan Maritime Self-Defense Force naval base's military vessel operations and manufacturing corridor generating elevated maritime and industrial emissions. Consistent Sea of Japan maritime breezes provide coastal ventilation, while the naval base's maritime industrial character represents Maizuru's most distinctive local emission source and the outstanding Wakasa Bay coastal exposure generally maintains good to moderate conditions throughout most of the year.

When is air pollution at its worst in Maizuru?

The biggest local contributors to pollution in Maizuru are traffic on the surrounding roads, airport and aviation operations, and textile and manufacturing operations, particularly once dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. Sea breezes typically keep conditions in check, except during still weather.

Are air quality levels in Maizuru 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.
