Sasagawa in Fukushima reflects the Fukushima Prefecture rural agricultural corridor position, with vehicle traffic on surrounding roads and agricultural operations contributing modest local sources. Pacific coastal maritime breezes provide background ventilation, while the area generally maintains good to moderate conditions and the 2011 Fukushima Daiichi nuclear disaster's radiological legacy adds unique environmental context to the broader regional awareness throughout the year.

Are air quality levels in Sasagawa 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.
