A long band of haze, roughly 100 kilometers wide, extends east-west southwest of Beijing. South of Beijing, the haze fans out, extending from the shores of Bo Hai to the shores of the Yellow Sea. Along the Yellow Sea shoreline, the haze is thick enough to obscure the coast.
Haze clogged the air over the coastal plain of eastern China in early October 2011. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this image on October 7, 2011.
Agricultural fires (visible as red outlines in the high-resolution image) contribute to the haze, but it probably also results from urban and industrial pollution. (EarthObservatory)
