RATP is constantly monitoring and assessing the quality of the air circulating in the underground railway enclosures. Monitoring is primarily based on compliance with the conditions of hygiene and cleanliness of RATP's spaces, both for passengers and staff.
The RATP laboratory carries out continuous measurements in 3 stations representative of the RATP's underground spaces (Châtelet, Franklin Roosevelt and Auber) that make up the SQUALES (Surveillance de la Qualité de l'Air de l'Environnement Souterrain) network.
This dataset corresponds to Châtelet station on line 4.
The measurements cover the usual climatic parameters (temperature, relative humidity), air renewal (carbon dioxide) and air quality (nitrogen oxides, particles).
