用气溶胶飞行时间质谱仪(ATOFMS)测量了2008年12月14日至23日期间上海大气中单个颗粒物的组成和尺寸。在整个过程中，碳质颗粒是气溶胶的主要类型。值得注意的是，在重霾事件中，随着二次组分(主要是硝酸铵和二次有机化合物)的添加，碳质颗粒的混合状态发生了显著变化，从新鲜的元素碳或生物质燃烧颗粒到老化的碳颗粒。我们的实时单粒子数据表明，混合态的变化对上海雾霾期间气溶胶消光的增加起到了重要作用。
The composition and size of individual atmospheric particles were measured by aerosol time-of-flight mass spectrometry (ATOFMS) in Shanghai for the period December 14–23, 2008. Carbonaceous particles were the dominant aerosol type in terms of number fraction during the entire period. Noticeably, the mixing state of carbonaceous particles showed dramatic changes from fresh elemental carbon or biomass burning particles to aged ones with the addition of secondary components, mostly ammonium nitrate and secondary organic compounds, during heavy haze events. Our real-time single particle data suggest that change in the mixing state played an important role in increasing light extinction of aerosols during haze events in Shanghai.
