Kōbe's air quality benefits from its exceptional Osaka Bay and Seto Inland Sea coastal position, with consistent Kii Channel and Pacific sea breezes providing reliable maritime ventilation. Vehicle traffic on surrounding expressways and the port, steel, and service corridor contribute local sources, while the Rokko Mountains rising steeply inland create dramatic topographic variation and Kobe generally maintains moderate to good conditions for a major Japanese industrial port city throughout most of the year.

When is air pollution at its worst in Kōbe?
In Kōbe, traffic on the surrounding roads, steel, cement, and chemical production, together with harbour and shipping traffic are the main local sources, with conditions worsening when dry, windy weather picks up. 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 Kōbe 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.
