Paper Abstract

The distribution of the probability density of fluctuations of the intensity of the scattered radiation of a focused laser beam (0.63 μm) in the near – ground (surface) atmosphere in a haze on a 130 m long path was measured. It is established that the probability density distribution has one maximum. The distribution had the right asymmetry or had a form close to symmetric. The form of distribution does not depend on the wind speed and its perpendicular component to the path at close atmospheric conditions, at close values of the scattering coefficient and the size of the haze particles. Most experimental probability density distributions are approximated by the gamma  distribution.
