When is air pollution at its worst in Ogōshi?
Ogōshi usually sees its poorest air quality when road traffic and manufacturing and food processing coincide with periods when the sea breeze weakens. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. Areas further inland without this ventilation tend to fare worse.
Are air quality levels in Ogōshi 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.
