摘要
卫星反演近地面PM2.5浓度是大气科学研究的重要领域之一。本文从卫星AOD数据来源、反演算法和建立AOD-PM2.5反演模型等关键技术阐述了近地面PM2.5浓度卫星反演的研究进展以及存在的问题。针对数学统计法、物理订正法和耦合反演法,分别分析了三种方法的优缺点,并重点分析了物理订正法中的湿度订正和垂直订正技术。
The retrieval of near surface -level PM2.5 concentration with satellite AOD is one of the important contents of atmospheric sciences. The research progress and problems was detailed during the establishment of AOD - PM2.5 model from AOD data sources, AOD retrieval algorithm and key methods. The inversion methods can be divided into three kinds： mathematical statistics model, physics model and coupling model. The advantages and disadvantages of the three methods were analyzed, the humidity and vertical corrections based on physical model method were detailed.
