Satellite view alerts China to soaring pollution

[摘要] Visitors to hazy Beijing can see how China's industrialization is fouling the air. Now data suggest that the situation is even worse than it looks, and pollution levels are rising. Direct satellite measurements of a key pollutant, nitrogen dioxide, show that the atmospheric concentrations of nitrogen dioxide inthe atmosphere have risen by 50% during the past decade and the build-up is accelerating even though China have introduced measures such as clean coal technologies to reduce air pollution.
