Sano's air quality reflects the flat Tochigi Prefecture southern Kanto Plain position, with vehicle traffic on surrounding roads and the strawberry farming, leather manufacturing, and services corridor contributing local sources. The flat Kanto Plain allows reasonable dispersal, while summer photochemical ozone from the broader Kanto corridor is the primary warm-season concern and Sano generally maintains moderate Japanese inland Kanto plain provincial city readings throughout most of the year.

When is air pollution at its worst in Sano?
In Sano, vehicle traffic, steel, cement, and chemical production, together with light manufacturing are the main local sources, with conditions worsening when summer heat and strong sunlight build up. Heat and sunlight combine with emissions to form ozone at ground level. Readings are generally lower during the cooler, cloudier months.
Are air quality levels in Sano 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.
