Urayasu's air quality reflects the flat Chiba Prefecture Tokyo Bay coastal position adjacent to Tokyo Disneyland and Disney Sea, with vehicle traffic on surrounding roads and the extraordinary theme park visitor traffic and the dense reclaimed land residential character contributing elevated NOₓ during peak periods. Tokyo Bay's industrial waterfront creates background emissions, while the theme park's extraordinary visitor concentration creates significant periodic vehicle emission peaks and Urayasu generally maintains moderate Tokyo eastern Bay readings throughout most of the year.

Are air quality levels in Urayasu 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.
