复杂海洋环境是空间光电探测的典型应用场景, 可见至长波红外波段海表反照率参数是海洋大气传输与背景辐射特性研究的重要内容。鉴于目前中国海域海表反照率数据缺乏的现状, 在多源卫星长时间观测海洋环境特性参数数据的统计分析基础上, 通过考虑海水叶绿素含量、气溶胶光学厚度、海表面风速和太阳入射角度等参数的复合影响, 建立了海表反照率的快速参数化应用模式, 获得了中国南海、东海、黄海和渤海等典型海域0.4~14 μm海表反照率谱线, 掌握了海表反照率的时空分布特征, 为海空光电工程应用提供基础数据支撑。

Complex oceanic environment(OE) is a typical scene in space photoelectric detection. Ocean surface albedo(OSA) from visible to far-infrared is of great importance to study of ocean atmospheric transfer and background radiative properties. However, the OSA in China Sea areas was less studied at present. This study built a fast parameterized OSA application model on the basis of statistical analysis of multiple-satellite measured long-time OE parameters. The new model took chlorophyll concentration of sea water, aerosol optical depth, ocean surface wind speed and solar illuminating angles into account. The fast parameterized application model of sea surface albedo was established, and the spectral curves of 0.4-14 micron sea surface albedo in the South China Sea, the East China Sea, the Yellow Sea and Bohai were obtained, and spatiotemporal features of OSAs were analyzed. These OSA spectrum provides fundamental data support for space photoelectric engineering applications above seas.
