NASA's Earth Observatory released an image of north China's haze taken from space yesterday. The image shows that a thick layer of haze blanketed the North China Plain on Oct 9.

Widespread smog has affected a large swath of north China as well as northwest China's Shaanxi province since Wednesday, with air conditions in northern Chinese cities including Beijing and Tianjin severely downgraded.
