Miyako's air quality reflects the Iwate Prefecture Pacific Ocean coastal position on Miyako Bay, with consistent Pacific maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the fishing, lumber, and reconstruction corridor contribute local sources, while the 2011 Tōhoku tsunami's devastating impact adds distinctive coastal reconstruction environmental context and Miyako generally maintains moderate to good conditions for a major Japanese northern Pacific coastal city throughout most of the year.

When is air pollution at its worst in Miyako?

Miyako usually sees its poorest air quality when traffic emissions, construction dust, together with shipbuilding and port operations coincide with periods when the sea breeze weakens. Sea breezes typically keep conditions in check, except during still weather. This coastal advantage is less pronounced during still, high-pressure weather.

Are air quality levels in Miyako 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.
