摘要: Ozone production efficiency (OPE) of ship plume was first evaluated in this study, based on ship-plume photochemical/dynamic model simulations and the composition data measured during ITCT 2K2 (Intercontinental Transport Chemical Transformation 2002) aircraft campaign. The averaged instantaneous OPEs (OPE(i)‾) estimated via modeling for ranged between 4.61 18.92, showing that values vary with extent chemical evolution (or stage) stability classes marine boundary layer (MBL). Together OPE(i)‾, equivalent (OPE(e)‾) entire were also estimated. OPE(e)‾ varied 9.73 (for stable MBL) 12.73 moderately MBL), which agreed well 12.85 observations. It found both model-simulated observation-based inside 0.29-0.38 times smaller than calculated/measured outside ship-plume. Such low insides due to high levels NO non-liner photochemistry. Possible implications OPE study global chemistry-transport are discussed.
