Naha's air quality benefits from its exceptional Okinawa Island Pacific Ocean and East China Sea dual-coastal position, with consistent northeast and southwest Pacific trade winds providing reliable and powerful maritime ventilation. Vehicle traffic on surrounding roads and the US military base operations and tourism corridor contribute local sources, while the extraordinary island trade wind exposure generally maintains Naha among Japan's cleaner major urban environments and the outstanding maritime ventilation effectively disperses local emissions throughout most of the year.

When is air pollution at its worst in Naha?
The biggest local contributors to pollution in Naha are traffic emissions, airport and aviation operations, together with seasonal tourism traffic, particularly once 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 Naha 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.
