QualAr — APA's air quality website and app
An open APA system that shows, for each monitoring station, how much PM10 and other pollutants are in the air right now and what today's air quality index is. There is a website and a phone app; this is where the DGS points people in its warnings about poor air quality.
Where you come across it. Days of dust from North Africa or smoke from wildfires, deciding whether to let a child play outside.
There are not many stations, and not every town has one: the nearest may be several dozen kilometres away, and its readings describe the air where it stands, not in your back garden.
