    Traffic restrictions associated with the Sino-African summit: Reductions of NOx detected from space

    (Wiley-Blackwell, 2007) Wang, Yuxuan; McElroy, Michael; Boersma, K. Folkert; Eskes, Henk J.; Veefkind, J. Pepijn

    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.
