Paper Abstract

In practical applications of lidar sounding, it is often difficult for the devices which work on various physical measurements to estimate meteorological parameters of the atmosphere. One of the difficulties is to define the slow vertical speed of the aerosol motion. This study is based on statistical processes at a spatial frequency domain after long-term observation of aerosol motion with the help of Micro Pulse lidar or other lidar systems. Basic assumption of the aerosol model is that an inhomogeneous aerosol distribution of certain size has initially uniform spatial arrangement. Simultaneously, we also assume that there are two more different aerosol distributions whose size is two times smaller than the initial one. The resulting aerosol field is a superposition of inhomogeneous aerosol distribution of the different sizes. The randomness of the aerosol distribution is provided with the random-number generator which changes the size and the position of each inhomogeneous aerosol distribution in the given limits. In this work, we have presented a 2D aerosol field whose size is 25.6 km in a vertical direction and 256 km in horizontal direction. The number of the basic aerosol sizes to which random factor is added is equal to seven. The size of inhomogeneous aerosols in a horizontal direction has changed from maximal value and the vertical size of inhomogeneities is setup by the special parameters from which shape of the each inhomogeneity is determined.
