More haze spread through eastern China in early November 2007. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite took this picture on November 5, 2007. Although not as thick as the haze in the region on October 23, this event still covered an area hundreds of kilometers across. This image shows haze confined predominantly to low-lying areas, and this is most apparent in the Taihang Shan Mountains where the gray haze accentuates the mountain valleys. Haze is also thick over Bo Hai.
