摘　　要：文章基于“高分五号”卫星大气环境红外甚高光谱分辨率探测仪(AIUS)数据,采用最优化反演算法,建立了大气成分廓线反演的业务化处理系统,并对反演结果进行了精度验证。该系统采用分层设计思想和模块化设计思路,具有手动和自动业务化处理的功能。将系统反演结果与微波临边探测仪(MLS)的2级官方产品和先验数据进行对比分析,O3反演产品在14~50km范围与MLS产品的相对偏差小于15%;H2O反演产品在18~70km范围与MLS产品的相对偏差小于15%;HCl反演产品在14~40km范围与MLS产品的相对偏差小于10%;N2O反演产品在10~35km范围与MLS产品的相对偏差小于10%;CO反演产品在14~55km范围与先验廓线的相对偏差小于15%。上述结果表明,反演系统具有良好的准确性和稳定性,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。Based on GF-5/AIUS measurement data and Optimal Estimation Method(OEM),this paper established a processing system to retrieve the atmospheric component profile operationally and verified the accuracy of the retrieval results.The system can process manually or automatically by adopting a layered design method and modular design ideas.Comparing the retrieval results with MLS official products or the priori profiles,the relative difference of O3 profiles is within 15%between 14km and 50km.The relative difference of H2O profiles is also with 15%at 18~70km.The relative difference of HCl and N2O profiles are within 10%at 14~40km,10%at 10~35km,respectively.The relative difference between retrieval CO and the priori profiles is within 15%at 14~55km.Therefore,the retrieval system has high precision and reliability,which can provide algorithmic and technical supports for atmospheric environmental monitoring and global climate change research in China.
