Tsu's air quality reflects the Mie Prefecture Ise Bay coastal position, with vehicle traffic on surrounding roads and the government, food processing, and manufacturing corridor contributing local sources. Consistent Ise Bay and Pacific maritime breezes provide reliable ventilation, while the bay's open geometry and the Kii Mountains rising inland create topographic variation and Tsu generally maintains moderate to good conditions for a major Japanese Ise Bay coastal city throughout most of the year.

When is air pollution at its worst in Tsu?
Pollution in Tsu typically rises when traffic emissions and textile and manufacturing operations combine, especially once onshore breezes fall calm. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. Areas further inland without this ventilation tend to fare worse.
Are air quality levels in Tsu 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.
