Toki's air quality reflects the Gifu Prefecture Toki River valley position — Toki being the gateway to Tajimi's ceramics corridor — with vehicle traffic on surrounding roads and the Mino ware ceramics, manufacturing, and agricultural corridor contributing distinctive kiln dust PM10 alongside primary vehicle sources. The surrounding valley hills create topographic variation, while summer photochemical ozone from the Chukyo corridor and the ceramics operations' distinctive kiln emissions represent the most locally unique air quality contributions throughout the year.

On 11 August 2026, air quality conditions in Toki will be similar to today, with AQI forecast at fair at 32.5/100. Pollution peaks around 11:00 AM (O3: 32.5/100).
When is air pollution at its worst in Toki?
Air quality in Toki tends to be worse when traffic emissions, heavy industry such as steel, cement, or petrochemical processing, as well as manufacturing and food processing build up and windblown dust events occur. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Heat and sunlight combine with emissions to form ozone at ground level.
Are air quality levels in Toki 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.
