| Abstract | P445; 对流层臭氧是一种污染气体,也是重要的温室气体,它可以影响人类健康、严重危害生态环境.本研究利用 WOUDC(The World Ozone and Ultraviolet Radiation Data Centre)发布的臭氧探空观测数据,评估了 2007-2018 年北半球地区 GOME-2A(Global Ozone Monitoring Experiment 2 aboard METOP-A)、OMI(Ozone Monitoring Instrument)卫星的对流层臭氧柱含量产品以及 TCR-2(Updated Tropospheric Chemistry Reanalysis)再分析对流层臭氧产品.分析结果表明,在赤道美洲地区、亚热带地区、欧洲西部和加拿大地区,GOME-2A与探空观测之间的相关系数最高可达0.56,相对偏差百分比绝对值不超过15％;在加拿大地区、美国东部地区和欧洲西部地区,OMI与探空观测之间的相关系数为0.65～0.72,标准化的均方根误差为0.47～0.56;就整个北半球区域而言,TCR-2对流层臭氧柱含量与探空观测之间的相关系数为0.41～0.95,标准化的均方根误差为0.18～0.48,优于其他两种卫星资料.此外,进一步探讨对流层臭氧柱含量趋势结果发现,TCR-2对流层臭氧柱含量变化趋势与探空观测结果较为一致.利用评估后的数据进一步分析发现,在赤道美洲地区、欧洲西部地区和中国地区对流层臭氧柱含量增加,而近年来在北极地区、加拿大地区和美国东部地区对流层臭氧柱含量减少. |

| Abstract_FL | Tropospheric ozone is an important air pollutant and greenhouse gas.It is harmful to human health and seriously harm the ecological environment.In this study,we use ozonesondes data from WOUDC(World Ozone and Ultraviolet Radiation Data Centre)during 2007-2018 to evaluate tropospheric ozone column products from GOME-2A(Global Ozone Monitoring Experiment 2 aboard METOP-A)and Ozone Monitoring Instrument(OMI)satellite,as well as tropospheric ozone products from Updated Tropospheric Chemistry Reanalysis(TCR-2).The results of the analysis show that in the equatorial American,subtropical,western European and Canadian regions,the correlation coefficients between GOME-2A and ozonesondes observations are up to 0.56,and the absolute values of the relative percentage deviations do not exceed 15％;in the eastern US.and western European regions,the correlation coefficients between OMI and ozonesondes observations are 0.65～0.72,and the standardized root-mean-square errors are 0.47～0.56;for the whole Northern Hemisphere region,the correla-tion coefficients between the TCR-2 tropospheric ozone column content and ozonesondes observations are 0.41～0.95,with standardized root-mean-square errors(RMSEs)of 0.18～0.48,which are better than the other two satellite data.Furthermore,the results indicate that the TCR-2 tropospheric ozone column trend is consistent with the trend direction of the ozonesondes observations.Through a more robust data assessment,it is evident that tro-pospheric ozone columns have increased in the equatorial Americas,Western Europe and China.Conversely,there has been a decrease in tropospheric ozone columns in the Arctic,Canada and the eastern United States. |
