Matsudo's air quality reflects the flat Chiba Prefecture Edogawa River corridor adjacent to Tokyo, with vehicle traffic on surrounding expressways and the dense urban 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 from the vast Kanto corridor is the primary warm-season concern and Matsudo generally maintains moderate Tokyo northeastern residential corridor readings throughout most of the year.

When is air pollution at its worst in Matsudo?
The biggest local contributors to pollution in Matsudo are traffic on the surrounding roads and petrochemical and refining operations, particularly once warm, sunny weather takes hold. Heat and sunlight combine with emissions to form ozone at ground level. This is far less of an issue outside the warmer months.
Are air quality levels in Matsudo 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.
