Kashiba's air quality reflects the Nara Prefecture Katsuragi River valley position adjacent to the Osaka metropolitan fringe, with vehicle traffic on surrounding roads and the footwear manufacturing — Kashiba being Japan's shoe manufacturing capital — and residential corridor contributing distinctive leather and rubber chemical emissions alongside primary vehicle sources. Osaka Bay breezes provide limited maritime ventilation, while the broader Kinki metropolitan regional background maintains moderate Nara Prefecture Osaka fringe corridor readings throughout most of the year.

When is air pollution at its worst in Kashiba?
Air quality in Kashiba tends to be worse when traffic emissions, steel, cement, and chemical production, as well as light manufacturing build up and onshore breezes fall calm. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Kashiba 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.
