Pollution over China can be seen from space
Fog and haze blanketed the North China Plain on January 10, 2012, making travel difficult. The Beijing airport cancelled 43 flights and delayed 80 more in the morning hours, when visibility dropped to 200 meters, according to state news reports. Provinces across the plain reported low visibility.
The haze decreased visibility in satellite images too. A milky, gray pall entirely blocks the ground from view in the top image, taken in the early afternoon by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite. Patches of white fog or low cloud hang below the gray haze. Winds had already begun to push the haze out of Beijing in the north, but the rest of the North China Plain still suffered from poor air quality. By the next day, when Aqua MODIS acquired the lower image, skies were mostly clear across the region.
Yikes!
