Hitachi-Naka's air quality reflects the Ibaraki Prefecture Pacific Ocean coastal position adjacent to Hitachinaka Port, with consistent Pacific maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the Kamine Park, port, and manufacturing corridor contribute local sources, while the outstanding Pacific coastal exposure and the Abukuma highlands rising inland create topographic variation and Hitachi-Naka generally maintains moderate to good Japanese Pacific coastal industrial readings throughout most of the year.

When is air pollution at its worst in Hitachi-Naka?
Air quality in Hitachi-Naka tends to be worse when traffic on the surrounding roads as well as manufacturing activity build up and dry spells bring strong winds.

Are air quality levels in Hitachi-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.
