Ube's air quality reflects the Yamaguchi Prefecture Ube Bay coastal position adjacent to the UBE Industries chemical complex, with vehicle traffic on surrounding roads and the chemical, cement, and coal corridor generating elevated industrial PM2.5 alongside vehicle sources. Consistent Seto Inland Sea maritime breezes provide coastal ventilation, while the chemical and cement industrial scale represents Ube's most distinctive local industrial air quality contribution throughout most of the year.

When is air pollution at its worst in Ube?
Ube usually sees its poorest air quality when traffic on the surrounding roads as well as heavy industry such as steel, cement, or petrochemical processing coincide with periods when dry, windy weather picks up. Dust carried on these winds adds substantially to particulate levels. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Ube 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.
