<![CDATA[Air Quality and Radiation Monitoring]]>Hello everyone. New user here, with perhaps a dumb question:

When I select my home location, in addition to the weather for nearby stations, I also see a number with a thumbs up symbol for Air quality and radiation monitoring.

What are the units of measurement, and where is this data derived from? Both the number and the symbol don't seem to change.

This gives me the Purple Air readouts from several stations in the vicinity. This isn't clickable on my phone, but works well on the web site.

Have you tried clicking on it?
Thumbs up is Moderate and it's an Air Quality Index.
After you click on an air quality station you'll see it's data over some time in the past. At the very bottom of that it reads "US Air Quality Index is based on the EPA standard, which is the highest AQI value for any pollutant."
Seems all stations are using that index - not sure if it changes to some other local index based on country.
