摘要

摘要: 海水透明度是描述海水光学特性的一个基本参数.根据水下光辐射传输理论及对比度传输理论,建立了海水透明度的半分析定量遥感模式.利用大量实测透明度资料对模式进行了验证,结果表明遥感反演透明度与实测透明度的相关系数为0.84,绝对平均误差为4.17m,相对平均误差为22.6%.最后利用建立的模式和Sea WiFS卫星资料制作了我国海域1999年的月平均透明度遥感产品.

Abstract: Water transparency (Secchi disc depth) is a basic parameter that describes the optical property of water.A semi-analytical inversing model of water transparency was provided using the theory of radiative transfer in water.The accuracy of this semi-analytical inversing model was validated by using the larger-scale in-situ data,and the result shows that the correlation is 0.84 with the relative error 22.6% and absolute error 4.7 m.Finally,using this inversing model of water transparency and SeaWiFS data,some time serial images of water transparency distribution were generated with monthly average in China seas in 1999.
