Naka in Ibaraki reflects the flat Ibaraki Prefecture Naka River coastal plain position, with vehicle traffic on surrounding roads and the manufacturing, agricultural, and services corridor contributing local sources. The flat Kanto Plain allows reasonable dispersal, while summer photochemical ozone from the broader Kanto corridor is the primary warm-season concern and Naka generally maintains moderate Japanese Ibaraki plain readings throughout most of the year.

When is air pollution at its worst in Naka?
In Naka, road traffic, heavy industrial and chemical processing, along with textile and manufacturing operations are the main local sources, with conditions worsening when summer heat and strong sunlight build up. Strong sunlight reacting with local emissions drives up ground-level ozone. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Naka 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.
