Kesennuma's air quality reflects the Miyagi Prefecture Kesennuma Bay Pacific Ocean coastal position, with vehicle traffic on surrounding roads and the fishing — Kesennuma being Japan's leading shark fin and bonito port — and manufacturing corridor contributing local sources. Consistent Pacific maritime breezes provide coastal ventilation, while the 2011 Tōhoku tsunami's extraordinary impact on this city adds distinctive coastal reconstruction environmental context and Kesennuma generally maintains moderate Miyagi coastal readings throughout most of the year.

When is air pollution at its worst in Kesennuma?
The biggest local contributors to pollution in Kesennuma are traffic emissions, manufacturing and food processing, together with ongoing construction work, particularly once the sea breeze weakens. 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 Kesennuma 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.
