The CityAir app collects air pollution data from reliable sources: proprietary, state, and research monitoring networks.
Data is updated in real time. To review measurements in the past, please, select necessary days in the upper right corner of the screen.
You can track the generalized air quality index (in the upper left corner of the screen) or view all the available parameters individually, by selecting the monitoring post of interest.
With the CityAir app, it's easy to choose when it's best to go for a run and figure out which city districts have the cleanest air.
We’re committed to expanding the amount of data and cities available.
Breathe clean air!
