Shirakawa in Fukushima reflects the Fukushima Prefecture Abukuma River valley position at 350 metres between the Nakadōri and Shirakawa highlands, with vehicle traffic on surrounding roads and the manufacturing, agricultural, and services corridor contributing local sources. Pacific coastal breezes and the Abukuma Highland provide background ventilation, while the area generally maintains moderate Fukushima southern corridor readings throughout most of the year.

When is air pollution at its worst in Shirakawa?
Shirakawa usually sees its poorest air quality when road traffic, textile and manufacturing operations, as well as agricultural burning coincide with periods when the sea breeze weakens. Sea breezes typically keep conditions in check, except during still weather. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Shirakawa 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.
