Shirayamamachi in Ishikawa reflects the Ishikawa Prefecture Hakusan mountain foothills position adjacent to the famous Shirayama-hime shrine, with vehicle traffic on surrounding roads and the religious tourism, agricultural, and light manufacturing corridor contributing very modest local sources. The Hakusan mountain backdrop and the Sea of Japan maritime influence provide background ventilation and the area generally maintains good to moderate conditions throughout most of the year.

Are air quality levels in Shirayamamachi 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.
