Abstract
The downwelling irradiance in water is highly variable due to focusing and defocusing of the sun and sky light by the wave-modulated water surface. While the time scales and intensity variations caused by wave focusing are well-studied, little is known about the induced spectral variability. Also the impact of variations of sensor depth and inclination during the measurement on spectral irradiance hasn't been studied much. We have developed a model which relates the variance of spectral irradiance to the relevant parameters of the environmental and experimental conditions. A data set from three German lakes was used to validate the model and to study the importance of each effect as a function of depth for the range 0 to 5 m.
