We aggregate air quality data from multiple sources, including citizen-operated sensors, experimental equipment, and government monitoring networks.

Using our own system, we assess the quality of incoming data; however, due to differences in sources and network density, the information should be considered approximate.

We publish this data to raise awareness about air quality and make environmental information more accessible.
