Yawata-shimizui in Kyoto reflects the Kyoto Prefecture Uji River confluence position adjacent to the Iwashimizu Hachimangu shrine, with vehicle traffic on surrounding roads and the manufacturing, residential, and heritage tourism character contributing local sources. The Osaka Bay breezes provide limited maritime ventilation from the south, while the broader Kinki metropolitan regional background maintains moderate Kyoto southern metropolitan heritage corridor readings throughout most of the year.

When is air pollution at its worst in Yawata-shimizui?
Yawata-shimizui usually sees its poorest air quality when vehicle traffic, manufacturing and food processing, as well as seasonal tourism traffic coincide with periods when maritime winds die down. Onshore breezes usually help clear the air, but pollution can build up when winds are light. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Yawata-shimizui 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.
