Imabari's air quality benefits from its exceptional Ehime Prefecture Seto Inland Sea and Kurushima Kaikyo channel coastal position, with consistent Seto Inland Sea and powerful Kurushima tidal maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the shipbuilding — Imabari being Japan's shipbuilding capital — and textile corridor contribute local sources, while the outstanding coastal exposure and the powerful tidal channel ventilation generally maintain Imabari among Shikoku's more moderately ventilated industrial coastal cities throughout most of the year.

When is air pollution at its worst in Imabari?

In Imabari, vehicle traffic, textile and manufacturing operations, and fishing fleet activity are the main local sources, with conditions worsening when windblown dust events occur. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.

Are air quality levels in Imabari 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.
