The statistics of light scattering phase function variations in the atmospheric surface layer of the Antarctic continent and in adjoining sea water areas was analyzed for the range of scattering angles from 20° to 160°. The mean values and square root deviations of the angular scattering coefficients for conditions of the Antarctic stations and at the coast of Antarctica are found. It is shown that the probability distribution of aerosol component of light scattering factors is close to lognormal. A high level of correlation between light scattering factors for various scattering angles is pointed out. It is established that 99% of variance of the scattering phase function is described by two first eigenvectors of the covariance matrix.
