Progress in lake water color remote sensing

Abstract

从卫星传感器、大气校正、光学特性测量、生物光学模型及水体辐射传输、水质参数反演方法等方面,系统分析了湖泊水色遥感的发展现状.湖泊水体物质组份的复杂性以及卫星传感器与实际需求的矛盾决定了湖泊水色遥感的难度.目前湖泊水色遥感在一些关键问题上仍没有实质性进步,离水色遥感监测的业务化尚有一段距离.令人欣慰的是,卫星传感器以及水色遥感反演算法的不断发展和进步,让我们看到了胜利的曙光.;We analyzed in detail the status quo of lake water color remote sensing from some aspects of satellite sensor, atmospheric correction, optical properties measurement, bio-optical model, radiative transfer model for the waters, and water quality parameter retrieval approach. It has a great difficulty to have practical application of water color remote sensing at a regional scale at present, depending on the complex components of lake water and on the inconsistency between satellite sensor and its actual demand from water quality monitoring. The progress in some key problems for lake water color remote sensing is still small, and there is a long way to go in applications of lake water color remote sensing. However, to be greatly pleasure, the satellite sensor and water color parameter retrieval approach are developing and making progresses, and the application in the future is hopeful.
