在最近的中非峰会期间，北京市政当局采取了积极措施，限制中国首都的车辆交通。我们发现，Aura卫星上的荷兰-芬兰臭氧监测仪器（OMI）检测到了相关NOx排放量的减少。使用三维化学传输模型对这些数据进行解释表明，在2006年11月4日至6日期间，NOx的排放量减少了40%。
Aggressive measures were instituted by the Beijing municipal authorities to restrict vehicular traffic in the Chinese capital during the recent Sino‐African Summit. We show that reductions in associated emissions of NOx were detected by the Dutch‐Finnish Ozone Monitoring Instrument (OMI) aboard the Aura satellite. Interpretation of these data using a 3‐dimensional chemical transport model indicates that emissions of NOx were reduced by 40% over the period of November 4 to 6, 2006, for which the restrictions were in place.
