Kanazawa's air quality benefits from its exceptional Sea of Japan coastal position in Ishikawa Prefecture, with consistent Sea of Japan maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the traditional crafts, pharmaceuticals, and university corridor contribute local sources, while the outstanding Sea of Japan coastal exposure and the Japanese Alps rising inland create dramatic topographic variation and Kanazawa generally maintains good to moderate conditions for a historic Japanese Sea of Japan coastal city throughout most of the year.

When is air pollution at its worst in Kanazawa?
Kanazawa usually sees its poorest air quality when vehicle traffic coincides with periods when onshore breezes fall calm. Onshore breezes usually help clear the air, but pollution can build up when winds are light. This coastal advantage is less pronounced during still, high-pressure weather.
Are air quality levels in Kanazawa 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.
