Calculation of air quality index of station data and mappibg with leaflet
İs there any example?
I don’t know of any but there might be! What have you been able to do so far?
You can get air quality data via e.g https://github.com/ropensci/ropenaq (many countries) and https://github.com/ropensci/rdefra (UK) and then you can transform to the AQI of your choice with your own script.
