About OpenAirMap

The project

OpenAirMap brings together reference stations, qualified micro-sensors and citizen sensors (NebuleAir, Sensor.Community, PurpleAir, MobileAir, SignalAir, and more) on a single map.

The goal is to make real-time and historical data that are usually scattered across platforms visible to citizens, local authorities and air-quality stakeholders.

Who operates this instance?

This instance is operated by AirCarto. OpenAirMap remains a joint AirCarto and AtmoSud project; openairmap.fr is operated by AirCarto.

How to read the map

Pick a pollutant (PM₂.₅, PM₁₀, NO₂, O₃, etc.) and a time step (scan, ≤2 min, 15 min, hour, day). Coloured markers follow the concentration thresholds shown in the legend.

You can toggle data sources, explore history, overlay modelling layers and open station or sensor details in the side panel.

Source details, licences and supported time steps remain available from the Information button on the map.

Partners and data

Data come from AtmoSud networks, AirCarto (NebuleAir, MobileAir), Sensor.Community, PurpleAir, SignalAir and other contributors depending on enabled sources.

Each provider remains responsible for its measurements. Licences and terms are summarised in the Information modal and on the producers’ websites when applicable.
