Sakurai's air quality reflects the Nara Prefecture Yamato River valley position adjacent to the famous Miwa Mountain Omiwa shrine — Japan's oldest Shinto shrine — with vehicle traffic on surrounding roads and the traditional crafts, tourism, and agricultural corridor contributing local sources. The Yamato basin's topographic variation and Osaka Bay breezes provide background ventilation and Sakurai generally maintains moderate Nara Prefecture metropolitan corridor readings throughout most of the year.

When is air pollution at its worst in Sakurai?
In Sakurai, traffic on the surrounding roads, crop farming, as well as seasonal tourism traffic are the main local sources, with conditions worsening when weather conditions turn unfavourable. Day-to-day conditions here depend heavily on the weather. Local weather patterns add further day-to-day variation.
Are air quality levels in Sakurai 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
