Beppu's air quality benefits from its exceptional Oita Prefecture Beppu Bay coastal position famous for its extraordinary concentration of hot springs, with consistent Pacific and Bungo Channel maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the tourism and hot spring operations contribute local sources, while the geothermal steam operations' distinctive H₂S and mineral vapour emissions represent Beppu's most uniquely geothermal local air quality characteristic and the outstanding coastal exposure generally maintains good to moderate conditions throughout most of the year.

When is air pollution at its worst in Beppu?
Pollution in Beppu typically rises when vehicle traffic and seasonal tourism traffic combine, especially once maritime winds die down. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. Areas further inland without this ventilation tend to fare worse.
Are air quality levels in Beppu 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.
