Daisen in Akita reflects the Akita Prefecture Sea of Japan coastal plain position, with vehicle traffic on surrounding roads and the rice farming, agricultural, and light manufacturing corridor contributing local sources. Consistent Sea of Japan maritime breezes provide reliable ventilation, while the outstanding coastal exposure and the Dewa Mountains rising inland create topographic variation and Daisen generally maintains good to moderate conditions for a Japanese Sea of Japan coastal agricultural city throughout most of the year.

When is air pollution at its worst in Daisen?
The biggest local contributors to pollution in Daisen are road traffic, manufacturing activity, and crop farming, particularly once maritime winds die down. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Daisen 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.
