Sōja's air quality reflects the Okayama Prefecture Takahashi River valley position adjacent to the Seto Inland Sea corridor, with vehicle traffic on surrounding roads and the industrial, manufacturing, and agricultural corridor contributing local sources. Consistent Seto Inland Sea maritime breezes provide background ventilation, while the surrounding Kibi highland creates topographic variation and Soja generally maintains moderate to good Okayama Prefecture inland corridor readings throughout most of the year.

When is air pollution at its worst in Sōja?
The biggest local contributors to pollution in Sōja are traffic emissions, manufacturing activity, along with agricultural activity, particularly once dry, windy weather picks up. Dust carried on these winds adds substantially to particulate levels. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Sōja 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.
