Isn't http://aqicn.org http://aqicn.org better? It seems quite real time and uses more stations at least above The Czech Republic.

- angled 8y agoBy far better, with greater coverage.
- simongray 8y agoI used to use that when I lived in Beijing, but when it comes to visualisation, nothing beats this site: https://www.airvisual.com/earth https://www.airvisual.com/earth You don't really get a feel for how the clouds of pollution move around in the other maps.
- gok 8y agoWow that's great!
- rsync 8y ago"I used to use that when I lived in Beijing, but when it comes to visualisation, nothing beats this site: https://www.airvisual.com/earth" https://www.airvisual.com/earth" Which sensor network does that site get data from ? Also, as I look at this map today, what is going on just northeast of Mexico city ?
- hedora 8y agoIt depends. You can pay purple air a few hundred dollars for a weather station that measures particulate matter but not ozone, etc. The upshot is that in most cities in the US, purple air has much denser coverage. For instance, Silicon Valley has ~4 government sensors, and one is shutting down. It has hundreds of purple air sensors. This makes a huge difference if you are trying to flee from wildfire smoke.
