@Wheats Thanks! 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.

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.

Cheers!
