Tsuchiura's air quality reflects the Ibaraki Prefecture Lake Kasumigaura position — Japan's second largest lake — with consistent lake breezes providing natural ventilation. Vehicle traffic on surrounding roads and the manufacturing, services, and agricultural corridor contribute local sources, while the outstanding lake ventilation and the Pacific coastal maritime influence provide reasonable dispersal and Tsuchiura generally maintains moderate to good Japanese lakeside city readings throughout most of the year.

When is air pollution at its worst in Tsuchiura?
Tsuchiura usually sees its poorest air quality when road traffic, manufacturing activity, as well as agricultural activity coincide with periods when onshore breezes fall calm. Onshore breezes usually help clear the air, but pollution can build up when winds are light. This coastal advantage is less pronounced during still, high-pressure weather.
Are air quality levels in Tsuchiura 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.
