Uki's air quality reflects the Kumamoto Prefecture Midori River coastal position on the Ariake Sea, with vehicle traffic on surrounding roads and the strawberry, agricultural, and services corridor contributing local sources. Consistent Ariake Sea maritime breezes provide coastal ventilation, while the outstanding coastal exposure generally maintains Uki among Kumamoto Prefecture's more moderately ventilated coastal agricultural cities throughout most of the year.

When is air pollution at its worst in Uki?
Pollution in Uki typically rises when vehicle traffic along with crop farming combine, especially once onshore breezes fall calm. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. This coastal advantage is less pronounced during still, high-pressure weather.
Are air quality levels in Uki 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.
