对流层臭氧具有气候效应，且浓度显著升高时将带来一系列重大的环境和生态问题。利用MAX-DOAS反演对流层臭氧廓线和柱总量，目前在国内的研究还较少。本研究利用MAX-DOAS采用查算表法、最优估算法、粒子群算法反演昆明和上海两地对流层臭氧廓线和柱总量，并结合ECC臭氧探空仪、Dobson分光光度计、Brewer光谱仪、卫星等对多种臭氧探测手段开展对比分析，进而改善MAX-DOAS的反演算法和参数配置。且将昆明和上海两地分别作为西部工业化相对偏低城区与东部典型复合型污染城区的代表，研究不同气候区城市群对流层臭氧变化特征，这对认识城市群环境过程具有重要现实意义和科学价值。可以期待本项目对MAX-DOAS反演算法提供一些新的思路，以及对东部与西部地区臭氧污染的差异及有效控制对策提供科学依据。

Tropospheric ozone has a climatic effect and causes a series of significant environmental and ecological problems at significantly high concentrations. Retrieval of the tropospheric ozone profile and columns using MAX-DOAS are still few studies in China at present. In this study, retrival of tropospheric ozone profile and columns by the look-up table method, the Optimal Estimation Method(OEM) and the Particle Swarm Optimization (PSO) on the MAX-DOAS technique.Then the inversion results compared with observations coming from the other detection equipment, such as ECC ozone sonde,Dobson spectrophotometer,Brewer spectrometer and satellite,to improve the inversion algorithm and parameter configuration. Taking Kunming as the representative of low industrialization urban areas and Shanghai as the representative of typical compound pollution urban area, the characteristics of tropospheric ozone variation in urban agglomerations of two different climatic regions were studied.This has important significance and scientific value for understanding the environmental process of urban agglomerations. It will hoped to look forward that this project will provide some new ideas for the MAX-DOAS inversion algorithm and provide a scientific basis about effective control measures for the differences ozone pollution in the eastern and western regions.
