particles deposition rate etc; 
- physico-mechanical and chemical properties of pollutants. 
The values of these parameters for any considered area can 
be determined empirically, from appropriate reference books or 
by certain functional dependencies. 
Owing to the development of GIS technologies and web 
services, the relevant spatial and meteorological data for almost 
anywhere on the Earth are generally accessible in machine-
readable form. And software interfaces and formats for 
processing are standardized. This allows us to significantly 
simplify and speed up the automation of data collection and 
processing to build information models, generate the necessary 
databases and develop our own software for solving scientific 
and engineering problems. 
In light of the above, the main goal of this work is to study 
the influence of vertical wind profile on the transport and 
diffusion of salt-dust aerosol emissions in the atmosphere over 
Aral Sea region.

A. Mathematical model 
Within the scope of semi-empirical theory of turbulent 
diffusion in the atmosphere and taking into account such 
factors as meteorological conditions, sedimentation rate of 
pollutant particles; interaction of pollutant particles with the 
land cover surface; mass transfer through the boundaries of the 
considered area and the absorption capacity of the 
environment, we propose the following model described by 
three-dimensional transport and diffusion equation in spherical 
coordinates:
