Chowdhary, J., L.D. Travis, and A.A. Lacis, 1995: Incorporation of a rough ocean surface and semi-infinite water body in multiple scattering computations of polarized light in an atmosphere-ocean system. In Atmospheric Sensing and Modelling, 29 Sep. 1994, Rome, Proc. SPIE, vol. 2311, p. 58, doi:10.1117/12.198585.

The use of accurate space-born polarimetric measurements to retrieve tropospheric aerosol characteristics is a promising remote sensing tool, but also imposes strong requirements on the atmosphere-ocean model in terms of its adequacy and on computational techniques in terms of their accuracy and efficiency. The present work is concerned with computing the reflection matrix of an atmosphere-ocean system within this context. We use the Ambartsumyan non- linear integral equation to obtain the reflection matrix for a semi-infinite homogeneous ocean body containing hydrosols. The reflection and transmission matrices of a statistically rough ocean surface are obtained using the standard Kirchhoff formulation, with shadowing effects taken into account. The reflection properties of the combined ocean body and ocean surface are obtained employing the adding method. We use the Fourier decomposition of the scattering matrices and separation of the first-order scattering to substantially reduce the computational burden. An atmospheric model containing aerosols and molecules is computed and added on the top of the ocean system using the adding/doubling method. We report preliminary computational data and discuss the variation of the degree of linear polarization of singly and multiply scattered radiation as a function of scattering geometry, surface roughness, and aerosol and molecular optical depth.
