Air Pollution in World: Real-Time Air Quality Index Visual Map (aqicn.org)

Curious why this is here. It was my go to source for AQI data when I was living in Beijing, and I believe it is a Chinese site but the only evidence I have for that is that they have good Chinese data and the CN after AQI in their name. Beijing has cleaned up slot but I’m surprised to see bad air still in Hebei and Shandong.

Someone needs to fix how that popup appears right over your cursor and with no delay.

Why no data from Las Vegas? Reno seems to have several data sources.
