This paper is devoted to derive remote sensing coefficient (RSC) or radiance reflection coefficient is a principal product of atmospheric correction algorithms applied to the remotely measured optical images of the ocean. The RSC contains information about angular structure of light radiance roughness of the ocean surface, and optical properties of the water. This presentation analyses RSC and presents it as a product of three physically different values or coefficients. The first coefficient depends on geometrical parameters of illumination and atmospheric optical properties, the second coefficient depends on roughness of the ocean surface, and the third coefficient depends on the optical properties of seawater. The approach used to derive the third in-water coefficient is valid for all levels of water turbidity - from the clearest open waters to the most turbid waters of river and extremely scattering waters of Yellow Sea type. It is shown that presented structure of RSC allows to increase precision of retrieving seawater optical properties from remotely measured optical images of the ocean.
