摘　　要：利用Aura卫星臭氧观测仪(OMI)反演的臭氧总量产品OMTO3对FY-3B TOU(2010年11月至2016年12月)臭氧总量产品进行验证分析,通过TOU与OMTO3相对偏差(RD)在空间和时间尺度上的比较分析来评估FY-3B TOU臭氧总量产品的可靠性。研究结果显示,赤道、南北半球中纬度的大部分区域RD值分布在2%~4%之间,南北极区扩到4%~6%和8%~10%之间,在赤道到两极地不同空间上RD随纬度升高而增大。除南北极地区域外,TOU臭氧总量RD月平均值均呈现出明显的季节变化特征,尤其南半球中纬度区域的季节变化较其他区域更为显著。南半球中纬度区域,波谷值出现在6月~7月,北半球中纬度区域,波谷出现在2月~3月。赤道区域RD值随卫星臭氧总量的变化波动较小,基本稳定在0.1%~2.9%之间,其余区域仅卫星臭氧总量在230 DU~500 DU之间时,RD才出现相对稳定的波动,TOU臭氧总量RD在不同区域对卫星臭氧总量值均出现了一定程度的依赖性。南北极区域SZA在457)~657)期间,TOU臭氧总量RD随SZA增大均呈正的下降趋势,在707)~807)之间均呈现小幅度回升趋势。从总体上来看,TOU臭氧总量RD值受SZA变化情况并不明显。This paper verifies the FY-3 B TOU total ozone product(November 2010 to December 2016)by using the Aura satellite ozone viewer(OMI) inversion of total ozone product OMTO3, with relative deviation(RD) of TOU and OMTO3 on space and time scale of the comparative analysis to assess the FY-3 B TOU total ozone product reliability. The results show that RD values in most of the middle latitudes of the equatorial and northern and southern hemispheres are in the range of 2%-4%, and the RD values in the north and south polar regions are in the range of 4%-6% and 8%-10%. In different spaces from the equator to the poles, RD increases with the increase of latitude. Except for the north and south polar regions, the monthly mean RD of total ozone TOU shows obvious seasonal variation characteristics, especially the seasonal variation in the middle latitude region of the southern hemisphere is more significant than other regions. Troughs occur in June and July in the mid-latitudes of the southern hemisphere, and in February and March in the mid-latitudes of the northern hemisphere. The Rd value in the equatorial region fluctuates slightly with the variation of the total satellite ozone, which is basically stable in the range of 0.1%~2.9%. In the other regions, RD fluctuates relatively stable only when the total satellite ozone is between 230~500 DU. The RD of TOU shows a certain degree of dependence on the total satellite ozone value in different regions. TOU RD shows a positive downward trend with the increase of SZA in the period of 457)-657) in the south and north polar regions, and shows a slight upward trend between 707)-807). On the whole, the RD of total ozone TOU is not significantly affected by SZA.
