Iga's air quality reflects the Mie Prefecture Nabari River valley's partial enclosure between the Suzuka and Kasagi mountains, with vehicle traffic on surrounding roads and the ninja heritage tourism, manufacturing, and agricultural corridor contributing local sources. The surrounding mountain ranges create topographic enclosure, while Ise Bay maritime breezes provide limited background ventilation and Iga generally maintains moderate conditions for a Japanese inland Mie Prefecture mountain valley city throughout most of the year.

When is air pollution at its worst in Iga?
Air quality in Iga tends to be worse when traffic on the surrounding roads, light manufacturing, together with crop farming build up and onshore breezes fall calm. Sea breezes typically keep conditions in check, except during still weather. This coastal advantage is less pronounced during still, high-pressure weather.
Are air quality levels in Iga 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.
