Afyonkarahisar's air quality reflects the western Anatolian plateau's Akarçay River valley at 1,021 metres, with vehicle traffic on surrounding roads and the marble quarrying, thermal springs tourism, and manufacturing corridor contributing elevated mineral dust PM10. The plateau allows reasonable dispersal on most days, while winter residential heating generates seasonal PM2.5 elevation and the marble quarrying's distinctive stone dust represents Afyonkarahisar's most locally unique air quality contribution throughout most of the year.

These wind events can carry dust in from the surrounding arid landscape. Coal and wood used for winter heating add substantially to particulate levels.
Are air quality levels in Hakodate 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.
