Mito's air quality reflects the flat Ibaraki Prefecture Naka River plain coastal position, with vehicle traffic on surrounding roads and the manufacturing, government, and university corridor contributing local sources. The flat Kanto Plain and the Pacific coastal maritime influence provide reasonable dispersal, while summer photochemical ozone from the broader Kanto corridor is the primary warm-season concern and Mito generally maintains moderate to good Japanese Kanto coastal plain readings throughout most of the year.

When is air pollution at its worst in Mito?
Air quality in Mito tends to be worse when vehicle traffic, heavy industrial and chemical processing, together with light manufacturing build up and hot, still weather settles in. Photochemical reactions in the heat push ozone levels higher. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Mito 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.
