Ōmiyachō in Shizuoka reflects the flat Shizuoka Prefecture coastal plain position, with vehicle traffic on surrounding roads and the manufacturing and residential character contributing local sources. Consistent Pacific maritime breezes provide coastal ventilation, while summer photochemical ozone from the broader Shizuoka metropolitan corridor is the primary warm-season concern and the area generally maintains moderate Shizuoka coastal readings throughout most of the year.

When is air pollution at its worst in Ōmiyachō?
Pollution in Ōmiyachō typically rises when vehicle traffic, petrochemical and refining operations, along with light manufacturing combine, especially once warm, sunny weather takes hold. Heat and sunlight combine with emissions to form ozone at ground level. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Ōmiyachō 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.
