论文摘要
化学传输模型（CTM）已被广泛用于提供控制臭氧（O3）污染的说明。但是，我们发现观察和基于模型的城市O3化学制度之间存在很大的差异：挥发性有机化合物（VOC）中国的限制性制度和弱氮氧化物（NOX）在观测中遇到了较低的氮（NOX）限制性方案，与与强大的NOX限制性制度相比，与中国有关。 O3矛盾的演变是由低估的城市NOX浓度和生物voc排放的可能高估引起的。因此，响应法规的NOX排放减少导致在2014 - 2020年间，中国省省北部的O3污染意外恶化，例如，中国省省的O3污染在Sichuan Basin（SCB）上增加了约7 ppb。 NOX引起的Urban O3变化导致2015 - 2020年的早期死亡率大约增加了3000例。
Chemical transport models (CTMs) have been widely used to provide instructions for the control of ozone (O3) pollution. However, we find large discrepancies between observation- and model-based urban O3 chemical regimes: volatile organic compound (VOC)-limited regimes over N. China and weak nitrogen oxides (NOx)-limited regimes over S. China in observations, in contrast to simulations with widespread distributions of strong NOx-limited regimes. The conflicting O3 evolutions are caused by underestimated urban NOx concentrations and the possible overestimation of biogenic VOC emissions. Reductions in NOx emissions, in response to regulations, have thus led to an unintended deterioration of O3 pollution over N. China provinces, for example, an increase in surface O3 by approximately 7 ppb over the Sichuan Basin (SCB) in 2014-2020. The NOx-induced urban O3 changes resulted in an increase in premature mortality by approximately 3000 cases in 2015-2020.
