海洋-大气耦合辐射传输模式

A Radiative Transfer Model in the Atmosphere-Ocean System

本文在已有的ＤＩＳＯＲＴ大气辐射传输模式基础上，耦合进一个海洋反射模式，在海洋反射模式部分，考虑了风生海表毛细波对海表双向反射的作用以及海洋中叶绿素、悬浮物、溶解有机物对海洋反射光谱的影响，同时，为应用方便，为此模式配套了完整的大气温、压、湿、微量气体、气溶胶及太阳地外谱数据集；此海洋反射模式和海洋－大气耦合辐射传输模式已与１９９５年９月５日黄海海面反射光谱的实测资料和飞行实验中的光谱仪测量数据进行了对比验证，模拟结果与实测数据基本上符合。

In this paper, ocean reflection is incorporated in the DISORT code. The ocean reflection model considers the effects of microwaves produced by wind on the bi-directional reflection, and the effects of chlorophyll, suspended matter and dissolved organic matter on the sea reflection spectrum. The models data of atmospheric temperature, pressure, humidity, trace gases, aerosol and extraterrestrial irradiance are also incorporated in this model for application to remote sensing and other fields. The reflectance model and the coupled model have been validated respectively by comparing with reflection spectrum measured by a shipborne and airborne spectrometer over the Yellow Sea in the east of China on Sept. 5, 1995. The simulations are basically in agreement with the measurements.
