A numerical technique is presented for computing radiance distributions in natural waters that have wind‐blown surfaces and depth‐dependent inherent optical properties. Input to the numerical model consists of the radiance distribution incident on the air‐water surface from above, the wind velocity, which specifies the state of randomness of the air‐water surface via a wind speed‐wave slope spectrum, the volume scattering and volume attenuation functions of the water body as functions of depth and wavelength, and the type of bottom boundary. Primary output from the model consists of directionally discretized radiances as functions of wavelength, direction, and depth throughout and above the water body.
