Haze hugged mountain slopes and filled valleys in eastern China in late October 2011. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite took this image on October 30.
An arc of haze extends hundreds of kilometers southwest of the capital city of Beijing, which lies just off the northeastern edge of the image. Especially thick haze hovers over the city of Xi’an. High ridges poke above the haze, which appears confined to lower elevations. The haze likely results from urban and industrial pollution.
A nearly opaque plume of haze snaked through eastern China on October 20, 2007. The haze likely results from industrial and vehicular emissions as China struggles to balance economic growth with a healthy environment.
