Abstract

A radiative transfer code to calculate the light field in the stratified hydrologic system is described and validated. The matrix-operator method is used. Chlorophyll-a and CDOM fluorescence and Raman scattering has also been incorporated into the code. Special emphasis is put on the treatment of phase function characterized by a sharp peak using δ-fit method. The code is validated by a model intercomparison for selected radiative transfer problems in the hydrologic system. Several profile data sets of inherent optical properties is obtained by using instruments of AC-s, Hydroscat-6 and others. These data sets were made in different hydrologic systems as Yangtze Estuary, and the East China sea. We use the IOPs measured in situ as input of radiative transfer code to simulate the light field in the hydrologic system. The preliminary result is presented in this paper.
