大气气溶胶光学厚度反演软件系统设计和实现

摘要

为了实现大气气溶胶光学厚度反演的要求,提出一种基于传统暗像元算法为基础的一体化软件系统设计方案,并完成系统的设计和气溶胶光学厚度反演实验.该系统的软件设计主要利用开源GDAL库对MODIS遥感数据进行提取和处理,并通过6S模型建立得出数据查算表.经过应用表明通过该软件系统使反演过程简单化、可视化,同时实现了气溶胶光学厚度反演的一体化的处理.%In order to achieve the requirement of inversion of Atmospheric Aerosol Optical Depth (AOD), the design of thernintegrated software system which is based on the traditional Dark Pixel Algorithm is put forward in this paper and completesrnthe system design and the inversion experiment of AOD. The design of the software system mainly uses open-source GDALrnlibrary for processing and extraction of MODIS data, and builds data lookup-table through 6S model. Application shows thatrnthe software system allows simplification and visualization of the inversion process, and achieves integrated treatment of AODrninversion.
