The contribution to the variance of sea surface slopes created by waves of different lengths is analyzed. Remote sensing data (radar, radiometric and optical measurements), as well as in situ measurements (measurements by laser slope meters, wave gauge sensors, special construction buoys) are used. The analysis took into account the following physical effects: the magnitude of the variance of the slopes, determined from remote sensing data, depends on the length of the probing radio wave; measured in situ variance of slopes is determined by the design characteristics of the measuring equipment. For wind speeds above 7-8 m/s, the dependence of the change in the variance of slopes in the range from the length of the main energy-carrying waves to the specified length ?0 is obtained. It is shown that the dependence of the variance of slopes on the length of the probing wave currently used in radiometric measurements significantly overestimates the variance values in the region where surface waves with a length ?0 < 0,1 contribute to the mirror reflection of radio waves. It is also shown that the contribution to the variance of slopes, which is given by waves longer than 10 m, is less than 20 %.
