Discover the data from the measuring stations that provide the levels of regulated air pollutants in Île-de-France.

For your information, if a station is under maintenance, it does not appear on the map.

You can click on each station for more details on the measurements.
Times are displayed in Universal Time (UT) : -1 hour in winter (from the last Sunday in October to the last Sunday in March) and -2 hours in summer (from the last Sunday in March to the last Sunday in October).

What is a measuring station? 

The monitoring system is sized to ensure regulatory monitoring and to provide levels of regulated air pollutants at any point in Ile-de-France. Depending on the location, this information is provided by the validated modeling system or via a measuring station. Additional measurement campaigns can be carried out in certain geographical sectors to refine the precision of the maps. 

A measuring station is a small laboratory equipped with different technologies and devices, from which measurements or samples are taken for counting and physico-chemical analyses, in order to determine the air quality at that location.
The location of permanent measuring stations and the pollutants measured are chosen so as to representatively document the air quality of the entire Île-de-France region.
