Edogawa's air quality reflects the eastern Tokyo metropolitan Edogawa River corridor adjacent to Chiba Prefecture, with vehicle traffic on surrounding expressways and the dense urban residential and commercial character contributing elevated NOₓ. The Edogawa River provides limited ventilation, while the broader Tokyo metropolitan regional emissions elevate background and summer photochemical ozone from the vast Kanto corridor is the primary warm-season concern throughout the year.

When is air pollution at its worst in Edogawa?
In Edogawa, traffic emissions together with heavy industrial and chemical processing are the main local sources, with conditions worsening when hot, still weather settles in. 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 Edogawa 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.
