Atsugichō in Kanagawa reflects the Kanagawa Prefecture Sagami River valley position adjacent to Atsugi, with vehicle traffic on surrounding roads and the manufacturing, JMSDF Atsugi Air Base aviation operations, and residential character contributing elevated local NOₓ. The Sagami valley provides limited ventilation, while the aviation operations represent the most distinctive local emission source and the area generally maintains moderate Kanagawa suburban corridor readings throughout most of the year.

When is air pollution at its worst in Atsugichō?

Air quality in Atsugichō tends to be worse when traffic emissions, aircraft operations at the local air base, along with manufacturing and food processing build up and still air allows pollutants to build up. Day-to-day conditions here depend heavily on the weather. Conditions can otherwise vary considerably with the weather.

Are air quality levels in Atsugichō 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.
