摘要:

臭氧成像廓线仪(Ozone Mapping and Profiler Suite, OMPS)可提供高垂直分辨率的臭氧垂直分布,能为研究大气臭氧的时空分布提供观测数据。为验证OMPS臭氧产品的精确性,选取2016~2018年北京地区的臭氧探空资料对OMPS v2.5臭氧廓线及v2.1臭氧总量进行对比分析。对比结果表明:在北京地区上空OMPS的臭氧垂直分布与臭氧探空资料在平流层中上层有较好一致性,相对偏差小于10%;在对流层中上层相对偏差较大,总体范围在15%~40%,部分情况超过80%;OMPS平流层臭氧总量与臭氧探空廓线积分的平流层臭氧总量相对偏差较小,平均偏差小于5%,均方根误差为18.3 DU,相关系数达到0.89;二者对流层臭氧总量平均偏差超过30%,对流层柱总量相关系数0.62。

Abstract:

Ozone Mapping and Profiler Suites (OMPS) provide vertical distributions of ozone with high vertical resolutions. They can also provide data for studying the temporal and spatial distribution of ozone in atmosphere. To verify the accuracy of OMPS ozone products, the ozone sounding data from 2016 to 2018 in Beijing were selected, comparing the OMPS v2.5 ozone profile with the total amount of v2.1 ozone profile. The results show that the vertical distributions of ozone in OMPS over Beijing are in good agreement with the ozone sounding data in the upper stratosphere, the relative deviation is less than 10%. The relative deviation in the upper stratosphere is in the range of 15%~40% and 80% in some cases; the relative deviation between the total ozone in OMPS stratosphere and the total ozone in the stratosphere integrated by the ozone sounding profile is little and the average deviation is less than 5%, the root mean square error is 18.3 DU, and the correlation coefficient is 0.89. The average deviation of total tropospheric ozone is more than 30%, and the correlation coefficient of total tropospheric column is 0.62.

Key words: Ozone profile    Ozone sounding    Total column ozone in troposphere    OMPS
