摘　　要：随着全球气候变化的加剧,大气痕量气体的监测日益受到重视。痕量气体柱浓度和廓线分布成为大气环境监测和全球气候变化研究的数据基础。风云三号E星和风云三号F星搭载的红外高光谱大气垂直探测仪Ⅱ型(HIRAS-Ⅱ)提供地气系统的高光谱分辨率红外辐射观测,可以用来反演高精度的大气成分廓线和柱浓度。基于风云三号E星HIRAS-Ⅱ,采用模块化设计和并行计算框架,集成大气廓线背景库和地表发射率数据库,使用最优化算法和RFM正向模型,设计研发了CH_(4)、O_(3)廓线及柱浓度产品和CO_(2)柱浓度产品生产的业务化反演系统。对该反演系统进行测试,并对反演得到的12景产品精度进行验证,结果表明:此反演系统运行稳定,产品具有较高的精度,能够为中国进行大气环境监测和全球气候变化研究提供算法和技术支持。With the intensification of global climate change,the monitoring of atmospheric trace gases has re⁃ceived increasing attention.The column concentrations and profiles distributions of trace gases become the data basis for atmospheric environmental monitoring and global climate change research.The Hyperspectral Infrared Atmospheric Vertical Sounder Ⅱ(HIRAS-Ⅱ)on board the Fengyun-3E and Fengyun-3F satellites provides high spectral resolution infrared radiometric observations of the Earth-gas system,which can be used to invert high-precision atmospheric compositional profiles and column concentrations.In this study,we have developed an operational inversion system based on HIRAS-Ⅱ.This system incorporates a modular design and parallel computing framework,integrating a global reference atmospheric profile database and surface emissivity data⁃base.Leveraging the optimal estimation methods and the RFM forward model,this system inverts the CH_(4),O_(3)profiles and column concentrations products as well as CO_(2)column concentrations products.The inversion system was tested and the accuracy of the 12 products obtained by the inversion system is verified.The results show that the inversion system operated stably and the products had high accuracy.The inversion system can provide algorithmic and technical support for atmospheric environment monitoring in China and global climate change research.
