Kakamigahara's air quality reflects the Gifu Prefecture Kiso River plain position adjacent to Nagoya, with vehicle traffic on surrounding roads and the Japan Air Self-Defense Force Kakamigahara Air Base aviation operations and the aerospace manufacturing corridor generating elevated NOₓ alongside primary vehicle sources. The flat Nobi Plain allows reasonable dispersal, while the aviation and aerospace manufacturing represent the most distinctive local emission sources and summer photochemical ozone from the Chukyo corridor is the primary warm-season concern.

When is air pollution at its worst in Kakamigahara?
Kakamigahara usually sees its poorest air quality when road traffic, aircraft operations at the local air base, as well as petrochemical and refining operations coincide with periods when warm, sunny weather takes hold. Photochemical reactions in the heat push ozone levels higher. Readings are generally lower during the cooler, cloudier months.
Are air quality levels in Kakamigahara 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.
