采用移动的DOAS技术对上海市内环高架道路（IRVR）所围成的中心城区NOx机动车排放进行了定量分析。在2009年10月世博会前、世博会开幕式和2010年闭幕式期间进行了三次现场测量活动。推导了NO2垂直气柱密度的时空分布规律，并研究了交通和风力条件对NO2垂直气柱密度的影响。IRVR地区的平均NO2排放率分别为2.1 ± 0.9吨/小时、2.8 ± 1.4吨/小时和2.7 ± 1.4吨/小时。中心城区每年的汽车氮氧化物排放量估计为2009年为（2.3 ± 1.0）× 104吨，2010年为（3.0 ± 1.5）× 104吨，全市为2009年和2010年的NOx排放量分别为（13.4 ± 5.9）× 104 t和（17.6 ± 8.4）× 104 t，考虑典型的NO/NO2比值、NOx寿命以及中心城区交通排放占全市的比例。移动的DOAS定量的机动车NOx排放量在上海市中心城区呈上升趋势，2006 - 2009年和2010年分别增长了1.6倍和2.1倍。由于风场的变化，未知的氮氧化物化学转化，并在AMFs的不确定性，系统的推导得到的最终氮氧化物排放率平均连续几天约为55%。
The mobile DOAS technique was used to quantify the NOxvehicle emission of the central urban area, enclosed by the Inner Ring Viaduct Road (IRVR), of Shanghai, China. Three field measurement campaigns were performed during the pre‐EXPO period in October 2009, the EXPO opening ceremony, and the closing ceremony period in 2010. The spatial and temporal distributions of NO2 Vertical Column Densities were derived, and the effects of traffic and wind conditions were studied. The averaged NO2 emissions rates from the IRVR area were determined to be 2.1 ± 0.9 ton/h, 2.8 ± 1.4 ton/h and 2.7 ± 1.4 ton/h for these three campaigns. The annual vehicle NOx emissions for the central urban area were estimated to be (2.3 ± 1.0) × 104 ton in 2009 and (3.0 ± 1.5) × 104 ton in 2010, and those for the whole city were (13.4 ± 5.9) × 104 ton in 2009 and (17.6 ± 8.4) × 104 ton in 2010, by considering a typical NO/NO2 ratio, NOx lifetime, as well as the traffic emission share of central urban area with respect to the entire city. The vehicle NOx emissions quantified by mobile DOAS were found to exhibit an increasing trend in the central urban area of Shanghai, by 1.6 times and 2.1 times from 2006 to 2009 and 2010. Due to wind field variations, unknown NOx chemical transformation, and uncertainties in AMFs, the systematic derivation of the final NOx emission rates obtained was about 55% for averaged several consecutive days.
