Air Quality API

Daily air quality index and hourly nitrogen dioxide, ozone, PM10 and PM2.5 near the surface plus the Saharan dust load for a point, from the GeoSphere chemical weather model (3 km). The index follows the EEA European Air Quality Index (1 good to 6 extremely poor; SO2 is not provided by the model). Map layers: the weather tiles aqi, no2, o3, pm10, pm25 and dust (see Weather API).
