Lombardy Air Quality Sensor Register (ARPA Lombardia)

datilombardia/air-quality-stations

The register of ARPA Lombardia air-quality sensors and their stations in Lombardy, Italy, from Open Data Regione Lombardia. Each row has the sensor id, the pollutant it measures and its unit, station id and name, altitude in metres, province code, municipality, start date and coordinates. Use it to find the sensor id for datilombardia/air-quality-readings. Choose how many rows to return (1 to 100), optionally filter by pollutant, province code or sensor id, and page with an offset. Rows come in sensor-id order and numbers arrive as text. Source data passed through unmodified and served by Eden Engine; not an official ARPA Lombardia or Regione Lombardia product.
