Anan's air quality benefits from its exceptional Tokushima Prefecture Pacific Ocean and Kii Channel coastal position, with consistent Pacific maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the chemical manufacturing corridor contribute local sources, while the outstanding coastal exposure generally maintains Anan among Tokushima Prefecture's more moderately ventilated coastal industrial cities throughout most of the year.

When is air pollution at its worst in Anan?
Anan usually sees its poorest air quality when traffic emissions, petrochemical and refining operations, along with textile and manufacturing operations coincide with periods when dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. Sea breezes typically keep conditions in check, except during still weather.
Are air quality levels in Anan 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.
