Switzerland air quality map

Map

Switzerland's air quality data comes from the National Air Pollution Monitoring Network (NABEL).

https://www.bafu.admin.ch/bafu/en/home/topics/air/state/data/air-pollution--real-time-data.html

It's a data map with time-series animation, you have to click to select between ozone O
₃, dust particles PM10, and nitrogen dioxide NO₂ (not to be confused with nitrous oxide N
₂O).

Measurements are in micrograms per cubic metre µg/m³ (the standard measurement).

There is no option indicated for PM2.5 particles (the kind of particles you get from wildfire smoke).

App

Switzerland also has an air quality app for iOS and Android called airCHeck.
