Airparif Open Data Portal

Airparif (the independent air quality observatory for the Greater Paris area) has established an open-data portal, which provides downloadable datasets and APIs with raw and validated air quality data, including pollutant concentrations by monitoring station (e.g., NO₂, PM₁₀, PM₂.₅, O₃), emissions, exposure indicators, air quality indexes, pollution episodes, mapped concentrations, and historical annual assessments for the Île-de-France region.
