Abstract
The possibilities and limitations of determining the skewness and kurtosis of sea surface slopes by spaceborne optical scanners are analysed. It is shown that these data do not allow precise retrieval of the values of skewness and kurtosis. The empirical probability density of slopes, determined according to the optical scanner data, is defined in a limited range of slopes. The Cox-Munk model used in the calculations is also defined in a limited area.
