We analyze the errors of retrieving the variance of the large-scale slopes of the sea surface from the microwave sounding data. The errors caused by the slope-distribution deviations from the Gaussian distribution are considered. The model of the Cox-Munk probability-density function is used for analysis. The average relative error of calculating the variance from the nadir-sounding data amounts to 12%. When calculating the slope variances using the sounding data in the case of several incidence angles, the error depends on choosing the incidence-angle range. In this case, the relative error of determining the sea-surface slope variance amounts to 10-20%. Deviations of the sea-surface slope distributions from the Gaussian distribution lead to underestimated calculated values of the slope variance for both nadir and oblique sounding.
