摘    要:基于美国宇航局NASA/AURA卫星臭氧监测仪OMI数据,分析了2005—2014年长三角地区及其典型城市对流层O_3、NO_2柱浓度和HCHO大气总柱浓度的时空分布特征。结果表明:10 a间,长三角地区对流层O_3柱浓度和HCHO总柱浓度呈现增长趋势,O_3增量为0.23ppbv/10 a,HCHO增量为0.07×10~(16) mol/(cm~2·10 a),对流层NO_2柱浓度呈现降低趋势,减量为0.06×10~(15)mol/(cm~2·10 a);长三角地区对流层O_3柱浓度最大值出现在3、4、5月,而对流层NO_2柱浓度最大值出现在1、12月,HCHO总柱浓度最大值出现在6、7月;对流层O_3柱浓度的高值区分布在长三角中部、北部区域,对流层NO_2柱浓度高值区分布于长三角中部,HCHO总柱浓度高值区相对分散,且四季的分布各不相同。O_3与NO_2和HCHO在时间和空间上呈现一定的相关性。

关 键 词:O3  NO2  HCHO  时间分布  空间分布

Abstract:Based on the data from the NASA/AURA satellite ozone monitoring instrument OMI, we analyzed the column concentration of tropospheric O3 and NO2in Yangtze River Delta and its typical cities, and also the temporal and spatial distribution of the atmospheric total column concentration of HCHO. The results turn out that during the last ten years, the concentration of O3 column and HCHO total column have a trend of increase, and the increase of O3 and HCHO concentration come to 0.23ppbv/10a and 0.07×1016mole/(cm-2.10a), respectively, while the concentration of NO2 column shows a decreasing trend, the reduction is 0.57×1015mole/(cm-2.10a). In the Yangtze River Delta, the maximum values of O3 column concentration happen in March, April and May, that of NO2 column concentration appear in January and December, and that of the HCHO total column appear in June and July. The high-value sector of O3 concentration located in the middle and northern part of the Yangtze River Delta and that of the NO2 located only in the middle part of the Yangtze River Delta. However, the high-value sector of HCHO total column concentration is relatively decentralized and varies from season to season. O3, NO2 and HCHO show some correlation from the aspects of time and space.
Keywords:O3  NO2  HCHO  temporal variation  spatial distribution
