英文摘要: Regional photochemical pollution caused by ozone (O-3) is serious in northern China during summer. In this study, we combined network observation data with the Fifth-Generation Pennsylvania State/National Centre for Atmospheric Research Mesoscale Model-Community Multiscale Air Quality (MM5-CMAQ) model system to simulate O-3 and its precursors'concentrations over northern China in June 2008. Comparisons of the simulations and observations indicate that the model can accurately reproduce the temporal and spatial distributions of temperature, humidity, and wind as well as the evolution of O-3 and its precursors over northern China. The monthly mean of the total oxidants (nitrogen dioxide + O-3) at 15:00 LT exceeded 90 ppbv across the North China Plain, thereby indicating significant photochemical pollution in this area. Vertical diffusion is the main source of the near-ground O-3, with contributions of more than 20 ppbv h(-1) in the urban areas. Dry deposition and chemical reactions are the main sinks for O-3, with contributions of more than 20 ppbv h(-1) and 7 ppbv h(-1) in the forest and urban areas, respectively. Although vertical diffusion is the main source of near ground O-3, photochemical reactions dominate the O-3 concentrations in the boundary layer because of the circulation between the lower and upper boundary layers. Considering that O-3 is mainly produced in the upper boundary layer, both nitrogen oxide and volatile organic compounds should be controlled on the North China Plain. The results presented here are intended to provide guidance for redefining strategies to control photochemical pollution over northern China. (C) 2016 Elsevier B.V. All rights reserved.
