    A-train look at the October pollution episode over China
    10.22.2010

    In early October 2010, a high-pressure weather system settled in over eastern China, and air pollution began to accumulate locally for nearly a week. By October 9 and 10, China's National Environmental Monitoring Center declared air quality "poor" to "hazardous" around Beijing and in 11 eastern provinces. Citizens were advised to take measures to protect themselves, and visibility was reduced to 100 meters (330 feet) in some areas. News outlets reported that at least 32 people died in traffic accidents caused by the poor visibility. Untold were the number of people suffering with asthma and other respiratory difficulties.

    October Haze Hovers Over Eastern China

    Haze clogged the air over the coastal plain of eastern China in early October 2011. The Moderate Resolution Imaging Spectroradiometer MODIS) sensor on NASA’s Aqua satellite captured this image on Oct. 7, 2011.

    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.

    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.

    A portrait from above of Shanghai’s pollution
    A NASA satellite captured the smog that has engulfed the city for the past week

    The thickest of the gray-brown haze centers around the low-lying contours of the Yellow River Valley and the western half of the North China Plain near the Luliang Mountains.
    You’ve been able to see the air for the last few days, now see what this massive Shanghai pollution cloud looks like from above.

    A NASA satellite captured an image of a “massive smog bank smothering huge portions of China.” It is directly over Shanghai and is exacerbated “by cool air and smoke from fires,” saysone report.

    Although it's easy to blame Shanghai's pollution on the poor air quality, NASA researchers offer up other aggravating causes.

    “A temperature inversion may be responsible for the build up of pollution over eastern China. Normally, air cools with altitude, but occasionally, a layer of cool air will be trapped beneath a layer of warm air. Since the cool air is more dense than the air above it, the two layers don’t mix and pollutants build up in the cool air near Earth’s surface."
