The Austrian Federal Enviromental Agency (Umweltbundesamt) maps air quality data from gauging stations distributed over the area of Austria. The recorded data from the sensors can be actualised by the user from the map interface. Used technologies are Google Maps and geonames.org for georeferencing.
Values for ozone, particulate matter, nitrogen dioxide, carbon monodixe and some other are recored and mapped. I’m not sure if the application works for any browser, becuase I had some troubles with Safari.
