I don't know much about UHI (maybe I'll do some surfing), but....
Currently, to "improve" air quality for the Olympics....
http://www.breitbart.com/article.php?id=D926NC681&show_article=1Beijing municipal government officials said last week that they are confident that a range of long- and short-term measures will ensure good air quality during the Games, which start Aug. 8.
These include banning half the cars from the road, halting most construction work and closing some factories for the duration of the Olympics
Isn't the large reduction in factory production and automobile traffic in Beijing acting as a large experiment on Urban Heat Island effects.
I'm thinking....
The large reduction in heat production may be contributing to the pollution retention, and increased fogging in the area.
