Radiance and degree of linear polarization of the upwelling and the downwelling radiation just above and below a ruffled ocean surface in a model atmosphere–ocean system are computed at the wavelengths of 0.5 and 0.75 μm with the doubling–adding method. Computational results show that: (1) maximum degree of polarization (Pmax) and radiance in the corresponding direction (Rmax) of the upwelling radiation below the ocean surface are strongly dependent on the oceanic condition and that Pmax is affected by the atmospheric condition. The effect of surface wind is negligible. (2) Pmax and Rmax of the downwelling radiation just above the ocean surface are strongly dependent on the atmospheric condition, but are little affected by oceanic and surface conditions. A combined measurement of Pmax and Rmax is expected to provide useful information to infer atmospheric and oceanic conditions.
