Abstract

The statistics of the variations of the aerosol component of the light-scattering distributions in the near-earth layer of the atmosphere in Antarctica are analyzed. It is found that the probability distribution for the angular coefficients of the aerosol scattering of light is close to log-normal. The methods of information-statistical analysis, based on the ratio of the useful signals to the measurement errors, are used to estimate the means, the variances, and the mutual correlation coefficients for the logarithms of the angular light-scattering coefficients. The information-statistical estimates of the means and variances are close to those obtained from the distribution quantiles on the assumption that the distribution of the logarithms of the angular scattering coefficients is normal and taking into account corrections for censorship of the data. A high level of mutual correlation is noted between light-scattering coefficients for different scattering angles. It is pointed out that the aerosol light-scattering distribution is correlated with the absolute humidity of the atmosphere. © 2005 Optical Society of America
