Haze mingled with clouds in the skies over eastern China on March 20, 2007, as imaged by Aqua's Moderate Resolution Imaging Spectroradiometer (MODIS). In this image, opaque white clouds and dingy gray haze obscure the view of the land surface while thick brown sediment clouds the shoreline of the Yellow Sea.
At least some of the haze results from pollution as China rapidly industrializes. Ubiquitous settlements in China appear in this image as tiny beige dots in a sea of green vegetation, especially near the Yellow Sea.
