| 1 | 珠江三角洲夏季臭氧区域污染及其控制因素分析显示文摘2006年夏季,在珠江三角洲(简称珠三角)开展了一次大型野外综合空气质量观测实验.实验包括了珠三角现有的环境监测网络和两个额外设置的超级观测站.本文基于环境监测网络的观测结果对区域臭氧污染状况和污染过程进行了分析,对各站点所记录的气团光化学属性进行了诊断.结果发现,两个超级站点分别对应着污染城市地区和下风向远郊区的光化学条件,它们较好地覆盖了区域尺度上主要的臭氧高值区.使用基于观测的模型对超级站上臭氧的光化学产生过程及臭氧控制区进行了分析.结果显示,第一,模式中的醛类化学和缺失的HONO化学对于臭氧光化学产生具有重要影响;第二,在城市地区,臭氧的光化学产生速率主要受人为源排放碳氢化合物控制;而在城市远郊区,臭氧的光化学产生速率主要受NO控制;第三,重要的人为源排放的碳氢化合物是烯烃和芳香烃.使用O′x和NOz的回归结果对臭氧产生效率进行了估算,发现城市和郊区的数值存在显著差异(分别为2.1和7.8),这从侧面支持了模型对于城市和郊区臭氧控制区属性的判断. | 陆克定 张远航 苏杭 邵敏 曾立民 钟流举 向运荣 张志忠 周崇光 Andreas Wahner | 2010 | 中国科学:化学2010，40，4： | 116 |
| 2 | Regional ozone pollution and key controlling factors of photochemical ozone production in Pearl River Delta during summer time显示文摘An intensive field campaign including measurements from the environmental monitoring network and from two super sites took place in the Pearl River Delta region in summer 2006.Using routinely measured O3 and NOx concentrations,the spatial and temporal variation of O3 and of the total oxidant concentrations was characterized.According to the spatial variability of NO2/NO,the two super sites were found to be representative of polluted urban and downwind suburban conditions.In addition,both sites were located in high O3 regions.In-depth diagnostic of photochemical ozone production processes and their key controlling factors are achieved with an observation-based model(OBM) to gain regional perspectives.Budget analysis and sensitivity model runs show that aldehyde and HONO chemistry had significant impacts on local photochemical ozone production rates.The analysis of calculated Relative Incremental Reactivities shows that photochemical ozone production rates are mainly sensitive to anthropogenic hydrocarbons(HCs) in the polluted urban areas.In the suburban areas,sensitivity to nitrogen oxide(NO) concentrations dominated.Key anthropogenic HCs in both areas are alkenes and aromatics.Significant differences of ozone production efficiencies are identified between the urban and suburban regions,consistent with the OBM diagnosed results. | CHANG ChihChung CHOU C.K.Charles Andreas Wahner | 2010 | Science China Chemistry2010，53，3： | 34 |
| 3 | Explicit diagnosis of the local ozone production rate and the ozone-NOx-VOC sensitivities显示文摘In the troposphere, ozone is a harmful gas compound to both human health and vegetation. Ozone is produced from the reaction of NO_x(@NO + NO_2) and VOCs(volatile organic compounds) with light. Due to the highly nonlinear relationships between ozone and its precursors, proper ozone mitigation relies on the knowledge of chemical mechanisms. In this study, an observation-based method is used to simulate ozone formation and elucidate its controlling factors for a rural site on the North China Plain. The instantaneous ozone production rate is calculated utilizing a box model using the dataset obtained from the Wangdu campaign. First, the model was operated in a time-dependent mode to calculate the ozone production rate at each time stamp. The calculated ozone formation rate showed a diurnal average maximum value of 17 ppbv/h(1-h diurnal averaged). The contribution of individual peroxy radicals to ozone production was analyzed. In addition, the functional dependence of calculated P(O_3) reveals that ozone production was in a NO_x-limited regime during the campaign. Furthermore, the missing peroxy radical source will further extend NO_x-limited conditions to earlier in the day, making NO_xlimitation dominate more of a day than the current chemical model predicts. Finally, a multiple scenarios mode,also known as EKMA(empirical kinetic modeling approach), was used to simulate the response of P(O_3) to the imaginary change in precursor concentrations. We found that ozone production was in the NO_x-limited region. However, the use of NO_2 measured by the molybdenum converter and/or the absence of a peroxy radical source in the current chemical model could over-emphasize the VOC-limited effect on ozone production. | Zhaofeng Tan Keding Lu Huabin Dong Min Hu Xin Li Yuhan Liu Sihua Lu Min Shao Rong Su Haichao Wang Yusheng Wu Andreas Wahner Yuanhang Zhang | 2018 | Science Bulletin2018，63，16： | 25 |
