Aomori's air quality benefits from its exceptional Mutsu Bay and Tsugaru Strait coastal position in northern Honshu, with consistent Pacific and Sea of Japan maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the apple farming, fishing, and tourism corridor contribute modest local sources, while the outstanding coastal exposure and the Hakkoda Mountains rising inland create dramatic topographic variation and Aomori generally maintains good to moderate conditions for a major Japanese northern coastal city throughout most of the year.

When is air pollution at its worst in Aomori?
In Aomori, traffic emissions, farming and agricultural processing, and fishing fleet activity are the main local sources, with conditions worsening when onshore breezes fall calm. Onshore breezes usually help clear the air, but pollution can build up when winds are light. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Aomori 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.
