China - January 6th, 2012

This image shows dense smog hanging over the North China Plain, completely obscuring much of the ground below. The haze probably contains mostly soot or black carbon and possibly some ground-level ozone. Smog frequently builds up in this way in northeastern China during the winter, because weather conditions trap pollutants over the plain. Here, the haze is also trapped in the area by the surrounding mountains.

The North China Plain is bordered on the north by the Yanshan Mountains and on the west by the Taihang Mountains at the edge of the Shanxi (‘western mountains’) plateau. To the south, it merges into the Yangtze Plain. From northeast to southeast, it fronts the Bohai Gulf (partially visible through the haze at the right edge), the highlands of Shandong Peninsula, and the Yellow Sea.
