Geod'air: the site that informs you about air quality

What is Geod'air?

The site Geod'air (Air Quality Observation Data Management) is the reference database on air quality in France. This website:

• Centralizes nationally produced pollutant measurement data from the Approved Air Quality Monitoring Associations (AASQAs);
• compile hourly, daily, seasonal and annual statistics on levels of concentration in ambient air in accordance with the rules laid down at European level.

You can an interactive map visualize the evolution of pollutants over time, by selecting one of the 550 stations in metropolitan and overseas. Depending on your search (by pollutant, data type, or date), you will get:

• a low-volume concentration of pollutants;
• a station card;
• data history since 2013;
• and the possibility of downloading in CSV format.

The data is available to all audiences (communities, NGOs, opinion leaders, experts, citizens...), in a simple format.

What are the different types of pollutants?

Geod'air make available concentration data for the main gaseous pollutants and particulate matter (benzene, nitrogen oxides, sulfur dioxide and carbon monoxide) from AASQA measurements as part of regulatory oversight.

The Ministry of the Environment offers on its website a description of the various pollutants: Air pollution: origins, situation and impacts.
