Haze collected over the Sichuan Basin in southern China on 13 November 2006. The Moderate Resolution Imaging Spectroradiometer (MODIS) flying onboard NASAs Aqua satellite took this picture the same day. In this image, dingy gray haze, mixed with white clouds, obscure the view of the basin. The haze extends southward over Laos, Vietnam, and the Gulf of Tonkin. West of the basin, however, snow-capped brown mountains show through clearskies.

China is rapidly industrializing, and industrial smog often clogs the nations skies. Some of the haze in this image may also result from agricultural fires. MODIS detects many of those fires as hotspots where surface temperatures are much greater than the surroundings. In this image, the hotspots appear as tiny red dots.
