Meguro's air quality reflects the southwestern Tokyo metropolitan residential corridor, with vehicle traffic on surrounding roads and the dense urban affluent 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 Meguro generally maintains moderate Tokyo southwestern residential corridor readings throughout most of the year.

When is air pollution at its worst in Meguro?
The biggest local contributors to pollution in Meguro are traffic on the surrounding roads along with steel, cement, and chemical production, particularly once 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 Meguro 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.
