The Air Quality — PM10 indicator shows the daily mean concentration of atmospheric particulate matter with aerodynamic diameter less than 10 micrometres (PM10). PM10 includes fine dust, pollen, spores, and particles generated by vehicular traffic, industrial combustion, agricultural activities, and natural processes such as wind erosion.
PM10 is one of the most regulated atmospheric pollutants. High concentrations reduce air quality, damage vegetation through deposition on leaf surfaces, compromise pollinator health by obstructing respiratory spiracles, and alter soil chemical properties. The European daily limit is 50 μg/m³ (not to be exceeded more than 35 times/year).
Data come from the CAMS model (Copernicus Atmosphere Monitoring Service) via the Open-Meteo Air Quality API, with 11 km spatial resolution and hourly updates. Daily values are calculated as 24-hour averages.
Data come from the Open-Meteo Air Quality API, based on the CAMS model (Copernicus Atmosphere Monitoring Service). The variable used is pm10 (PM10 concentration at ground level). For each day, the average of hourly values is calculated. Data are interpolated to the site's geographic position.
