| 摘 要： | 利用OMI卫星观测的对流层NO2柱浓度和113个重点城市地面ρ(NO2)监测数据，结合753个监测站降水资料以及中国气象局气象信息综合分析处理系统(MICAPS)气压场数据，研究了中国NO2的季节分布特征及其影响因素.结果表明:卫星遥感数据和地面监测数据同步显示了中国NO2浓度冬季峰值、夏季谷值的季节分布特征；月降水量与地面监测的ρ(NO2)呈负相关，相关系数为0.71.气压场平均结果表明，边界层气压场的特征是影响NO2浓度季节分布的另一个主要因素.

| Abstract: | Using tropospheric NO2 columns derived from OMI observations,NO2 measurements at 113 major monitoring sites,753 meteorological observations of rainfall and sea-level pressure field data from MICAPS,this paper studies seasonal distribution characteristics of NO2 in China and influencing factors.The findings indicate that the satellite remote sensing data and observation data on the ground synchronously reveal the seasonal characteristics of NO2 concentration in China,which reaches peaks in winter and is lowest in summer.Monthly mean rainfall and seasonal distribution of NO2 concentration were inversely correlated,with a correlation coefficient of 0.71.The average air pressure field result showed that the characteristics of planetary boundary layer(PBL) pressure field was another main factor influencing seasonal variability of NO2 concentration. |
