Description

RATP continuously carries out monitoring and expertise on air quality circulating in underground railway enclosures. Monitoring is based primarily on compliance with the conditions of hygiene and cleanliness of the RATP’s spaces, both for travellers and for staff. The RATP laboratory performs continuous measurements at 5 stations representative of the RATP underground spaces (Châtelet, Franklin Roosevelt and Auber, Châtelet RER A and Nation RER A) which constitute the squal network (Monitoring of Air Quality of the Underground Environment). This dataset corresponds to the station Nation on line A of the RER. Measurements cover the usual climatic parameters (temperature, relative humidity), air renewal (carbon dioxide) and air quality (nitrogen oxides, particulate matter). This network automatically produces more than 200000 raw data per year. The hourly averages of these measurements are the published database. Spot measurement campaigns also allow monitoring of other parameters, such as ultrafine particles, aldehydes, monocyclic or polycyclic aromatic hydrocarbons.
