Fukuoka's air quality benefits from its exceptional Hakata Bay and Genkai Sea coastal position on Kyushu, with consistent Tsushima Strait and East China Sea maritime breezes providing reliable ventilation. Vehicle traffic on surrounding expressways and the services, technology, and port corridor contribute local sources, while the outstanding coastal exposure generally maintains Fukuoka among Japan's more moderately ventilated major coastal cities and transboundary pollution from Chinese and Korean industrial sources on westerly winds is the primary regional background concern.

When is air pollution at its worst in Fukuoka?
In Fukuoka, traffic emissions along with fishing fleet activity are the main local sources, with conditions worsening when windblown dust events occur. 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 Fukuoka 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
