Amakusa's air quality benefits from its exceptional Kumamoto Prefecture Amakusa Islands East China Sea and Yatsushiro Sea dual-coastal position, with consistent East China Sea maritime breezes providing reliable ventilation around the famous Amakusa hidden Christian heritage islands. Vehicle traffic on surrounding roads and the fishing, agriculture, and religious tourism corridor contribute modest local sources, while the outstanding island coastal exposure generally maintains Amakusa among Kumamoto Prefecture's more moderately ventilated island environments throughout most of the year.

When is air pollution at its worst in Amakusa?
Amakusa usually sees its poorest air quality when traffic on the surrounding roads, crop farming, as well as port and shipping activity coincide with periods when the sea breeze weakens. Onshore breezes usually help clear the air, but pollution can build up when winds are light. This natural ventilation is one reason coastal areas often see better readings than inland cities.
Are air quality levels in Amakusa 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.
