| 英文摘要 | An extensive set of primary and secondary pollutants was measured at a ground site in a remote location in the Yellow River Delta, China during the Ozone Photochemistry and Export from China Experiment (OPECE) from March to April 2018. The measurements include volatile organic compounds (VOCs), peroxyacyl nitrates (PANs), ozone (O-3), particulate species, nitrogen oxides (NOx), and SO2. Observed VOC mixing ratios were comparable to those measured in heavily polluted cities in the U.S. and China. The VOC source signatures suggest a strong influence from Oil and Natural Gas (O&NG) emissions with potentially large contributions from Liquified Petroleum Gas (LPG) sources as well. Consistently elevated concentrations of O-3, PAN, and its rarely measured homologs peroxybenzoylic nitric anhydride (PBzN) and peroxyacrylic nitric anhydride (APAN) at the OPECE site indicate complex photochemi(s)try in a heterogeneous VOC environment. Diagnostic 0-D box model simulations are used to investigate the budgets of ROx (OH + HO2 + RO2), and the rate and efficiency of O-3 production. Model sensitivity calculations indicate that O-3 production at OPECE site is VOC limited in spring. This suggests that reduction in VOCs should be a priority for reducing O-3, where production and fugitive emissions from O&NG provide an attractive target. While initial reductions in NOx might increase O-3 production, reduction of NOx along with VOCs will be a necessary step to achieve long-term ozone reduction. Plain Language Summary We observed the trace gas composition of the lower atmosphere in a remote location in the Yellow River Delta (YRD), China. The composition and source signatures of VOCs suggest a strong influence of Oil and Natural Gas (O&NG) emissions as well as urban emissions. Elevated levels of secondary pollutants such as O-3 and PANs indicate significant photochemical processing of volatile organic compounds (VOCs) and NOx. Both measurements and diagnostic model simulations suggest that reduction in anthropogenic VOCs is a necessary step to reduce O-3 in the YRD region in spring, where O&NG and petrochemical facilities are important sources of such VOCs. |
