AB  - Data from an in situ monitoring network and five ozone sondes are analysed during 
      August of 2012, and a high tropospheric ozone episode is observed around the 8th 
      of AUG. The Community Multi-scale Air Quality (CMAQ) model and its process 
      analysis tool were used to study factors and mechanisms for high ozone mixing 
      ratio at different levels of ozone vertical profiles. A sensitive scenario 
      without chemical initial and boundary conditions (ICBCs) from MOZART4-GEOS5 was 
      applied to study the impact of stratosphere-troposphere exchange (STE) on 
      vertical ozone. The simulation results indicated that the first high ozone peak 
      near the tropopause was dominated by STE. Results from process analysis showed 
      that: in the urban area, the second peak at approximately 2 km above ground 
      height was mainly caused by local photochemical production. The third peak (near 
      surface) was mainly caused by the upwind transportation from the suburban/rural 
      areas; in the suburban/rural areas, local photochemical production of ozone 
      dominated the high ozone mixing ratio from the surface to approximately 3 km 
      height. Furthermore, the capability of indicators to distinguish O(3)-precursor 
      sensitivity along the vertical O(3) profiles was investigated. Two sensitive 
      scenarios, which had cut 30% anthropogenic NO(X) or VOC emissions, showed that 
      O(3)-precursor indicators, specifically the ratios of O(3)/NOy, H(2)O(2)/HNO(3) 
      or H(2)O(2)/NO(Z), could partly distinguish the O(3)-precursor sensitivity 
      between VOCs-sensitive and NOx-sensitive along the vertical profiles. In urban 
      area, the O(3)-precursor relationship transferred from VOCs-sensitive within the 
      boundary layer to NOx-sensitive at approximately 1-3 km above ground height, 
      further confirming the dominant roles of transportation and photochemical 
      production in high O(3) peaks at the near-ground layer and 2 km above ground 
      height, respectively.
