一、前言在海洋水色遥感信息的定性和定量分析中有二个需要解决的主要问题:一是,从遥感资料中提取出有用的信息;这包括推算海-气界面的反射、大气衰减和散射的影响;二是,要说明海洋水色光谱与海水光学特性的关系。第二个问题的关键是把海水光学特性与水色光谱R(λ)的关系公式化。本文应用Schuster的著名海中辐射传输的两流模式,计算海洋水色光谱,即把水色光谱与水光学特性的关系公式化,为遥感中的海洋环境要素的谱分析提供理论依据和方法。
I. Preface There are two main problems that need to be solved in the qualitative and quantitative analysis of ocean color water remote sensing information: firstly, to extract useful information from remote sensing data; this includes calculating the reflection of sea-air interface, atmospheric attenuation and scattering The second is to explain the relationship between marine aqua spectroscopy and seawater optical properties. The crux of the second problem is to formulate the relationship between seawater optical properties and the aqua spectrum R (λ). In this paper, Schuster’s famous two-flow model of the sea radiation transmission is used to calculate the ocean color spectrum, that is to say, the relationship between the water color spectrum and the water optical properties is formulated, which provides a theoretical basis and method for the spectral analysis of marine environmental elements in remote sensing.
