Satsumasendai's air quality reflects the Kagoshima Prefecture Sendai River coastal position on the East China Sea, with vehicle traffic on surrounding roads and the Sendai Thermal Power Station and manufacturing corridor contributing elevated industrial emissions. Consistent East China Sea maritime breezes provide coastal ventilation, while the power station's industrial scale represents Satsumasendai's most distinctive local air quality contribution and the coastal position generally manages readings on most wind days throughout most of the year.

When is air pollution at its worst in Satsumasendai?
Air quality in Satsumasendai tends to be worse when road traffic, the local power plant, together with manufacturing and food processing build up and dry, windy weather picks up. These wind events can carry dust in from the surrounding arid landscape. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Satsumasendai 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.
