title: Solar radiance distribution in deep natural waters including fluorescence effects.
abstract: The limit values for large depths of the upward and downward distribution functions for (diffuse) fluorescence emitting wavelengths are examined. It is demonstrated that even in strong fluorescence emissions these functions do not always correspond to a diffuse radiance field. A model is proposed to describe the depth dependence of the distribution functions.
