Air quality. Real-time data

The Comprehensive Air Quality System of the City Council of Madrid allows to know at all times the levels of air pollution in the municipality. In this data set you can get the updated information in real time, updating this data every hour, and this update will be made between 20 and 30 minutes. Important: these real-time data are those that automatically leave the measuring stations and are pending review and validation. See the 'Air Quality Data Interpretation' file below in the 'associated documentation' section.
