Shikokuchūō's air quality reflects the Ehime Prefecture Seto Inland Sea coastal position at the Shikoku-Honshu corridor, with vehicle traffic on surrounding roads and the paper and pulp manufacturing — Shikokucho being Japan's paper production heartland — generating elevated industrial PM2.5 and distinctive organic aerosols. Consistent Seto Inland Sea maritime breezes provide coastal ventilation, while the paper manufacturing operations' distinctive organic emission profile represents Shikokucho's most locally unique industrial air quality characteristic throughout the year.

When is air pollution at its worst in Shikokuchūō?
Pollution in Shikokuchūō typically rises when vehicle traffic and manufacturing activity combine, especially once dry spells bring strong winds. These wind events can carry dust in from the surrounding arid landscape. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Shikokuchūō 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.
