Koga in Fukuoka reflects the Fukuoka Prefecture northern coastal position on the Genkai Sea adjacent to the Fukuoka metropolitan area, with vehicle traffic on surrounding roads and the residential and commercial character contributing local sources. Consistent East China Sea maritime breezes provide ventilation, while transboundary Chinese and Korean industrial pollution on westerly winds is the primary regional concern and Koga generally maintains moderate Fukuoka metropolitan northern corridor readings throughout most of the year.

When is air pollution at its worst in Koga?
Pollution in Koga typically rises when traffic emissions, especially once 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 Koga 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.
