Beykoz's air quality benefits from the greater Istanbul metropolitan area's northernmost Asian shore position on the Bosphorus Strait adjacent to the Belgrad Forest, with consistent Black Sea and Bosphorus breezes providing reliable maritime ventilation. Vehicle traffic on surrounding roads and the coastal residential and forest character contribute modest local sources, while the Black Sea proximity and the substantial forest backdrop provide some of the best natural clean-air buffering of any Istanbul Asian district throughout most of the year.

When is air pollution at its worst in Kyŏngju?
In Kyŏngju, traffic on the surrounding roads is the main local source, with conditions worsening when the sea breeze weakens. Sea breezes typically keep conditions in check, except during still weather. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Kyŏngju 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.
