Tottori's air quality benefits from its exceptional Sea of Japan coastal position adjacent to the famous Tottori Sand Dunes, with consistent Sea of Japan maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the crab fishing, tourism, and government corridor contribute modest local sources, while the outstanding Sea of Japan coastal exposure and the Chugoku Mountains rising inland create topographic variation and the windblown sand dune's distinctive mineral dust adds a uniquely geological local PM10 contribution throughout the year.

When is air pollution at its worst in Tottori?
Tottori usually sees its poorest air quality when road traffic, fishing fleet activity, along with seasonal tourism traffic coincide with periods when dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Tottori 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.
