Musashino's air quality reflects the western Tokyo metropolitan corridor adjacent to Kichijoji, with vehicle traffic on surrounding roads and the Inokashira Park, university, and dense residential and commercial character contributing elevated NOₓ. The flat Kanto Plain allows reasonable dispersal, while the broader Tokyo metropolitan regional emissions elevate background and summer photochemical ozone is the primary warm-season concern and Musashino generally maintains moderate to good Tokyo western suburban readings throughout most of the year.

When is air pollution at its worst in Musashino?
Musashino usually sees its poorest air quality when traffic on the surrounding roads along with heavy industrial and chemical processing coincide with periods when summer heat and strong sunlight build up. Photochemical reactions in the heat push ozone levels higher. Cooler temperatures for the rest of the year keep this in check.
Are air quality levels in Musashino 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.
