【摘要】 海洋水色遥感的基础之一是海洋光谱特性的精确测量与分析。海洋光谱分析对改进反演算法、最佳波段选择、辅助大气修正、系统定标与校验等方面有很大作用,因此这方面的研究越来越受到重视。本文在海洋光谱机理的基础上,就光谱现场测量方法和分析处理方法进行了探讨,并给出了一个典型海域的光谱数据分析处理结果。由于我国尚缺乏满足水色应用要求的水下光学测量仪器,因此提出了一种利用瞬态光谱仪在水面以上进行离水辐射率测量与分析的方法。更多还原

【Abstract】 Oceanic in situ optical data measurement and spectral analysis is essential to any ocean color sensing project. Oceanic spectral analysis will help improve pigments’ retrieval algorithm,atmospheric correction algorithm for Case Ⅱ waters selection sensor’s bands,and vicarious calibration and validation. This paper first gives a brief introduction to the principle of ocean color,then gives a detailed processing procedure and typical results in the Yellow Sea area. As we have no suitable under-water optical instrument, we have proposed a method of spectral measurement with above-water spectrometer.更多还原
