Description

Beijing to Improve Pollution Monitoring - Thick smog shrouds China's capital, Beijing. There has been a public outcry over the methods authorities use to measure air quality, and Beijing residents say official figures understate the severity of the pollution. Local authorities publish readings of pollutant particles 10 micrometers or more in diameter, and last month said they had met their target for "blue sky" days in 2011. But a spokeswoman for Greenpeace says the measuring system is out of date.
