Lombardy Air Quality Sensor Readings (ARPA Lombardia)

datilombardia/air-quality-readings

Hourly air-quality readings from ARPA Lombardia sensors in Lombardy, Italy, from Open Data Regione Lombardia. Each row has the sensor id, the hour of the reading, the value (as text), a validity status and an operator id. Newest hour first. Choose how many rows to return (1 to 100), optionally narrow to one sensor id, and page with an offset. A row whose status is NA carries -9999, which means no data. The rows carry no pollutant name or unit; look the sensor id up with datilombardia/air-quality-stations. Source data passed through unmodified and served by Eden Engine; not an official ARPA Lombardia or Regione Lombardia product.
