Dust and Haze Blow Across China

April 18, 2013
Blowing desert dust adds to existing haze in the eastern basin of China. The grayish haze spread across most of the center of the image is likely a mixture of urban, industrial, and residential air pollution, possibily mingling with smoke from agricultural and other fires. Around Beijing, in the top center of the image, the haze includes a large, yellowish-tan plume of dust. Spring brings numerous dust storms to eastern China from the interior deserts, such as the Gobi Desert. According to regional news, this combination of air quality problems caused the Beijing Environmental Protection Bureau to lower the air quality index to its most unhealthy level and to advise people to stay indoors until the air clears.
