The plumes of smoke from the pipes of the industrial enterprises characterize the processes of distribution of pollution in the atmosphere. They are well visible in the satellite images of territories of the cities. This study is aimed at the assessment of parameters of emissions and characteristics of the atmospheric boundary layer according to satellite information. To this end, the hydrodynamics equations are used. The vertical profile of the wind is estimated with the use of the Ekman model and data of aerological sounding. On additional height of a source is calculated by the value of an angle of the sun above the horizon and the location of a shade plumes of smoke in the satellite images. For controlling the accuracy of estimation of an additional height of raising a plumes of smoke, the numerical method is used. It is based on the ratios with allowance a dynamic impulse of emission and a heat flux of buoyancy. In relation to the winter conditions, estimates of effective heights of raising plumes of smoke for large thermoelectric plants of Novosibirsk are carried out. With the use of meteorological and satellite information, the wind profiles in the lower atmosphere are calculated. The methods offered can be used for the analysis of processes of air pollution in the city.
The method to calculate the wind fields in the low atmosphere based on the use of satellite images of smoke plumes from the chimneys of industrial plants various heights is proposed. The model is based on Ekman layer equations. The results of calculations of the vertical profiles of wind velocity components and the coefficient of the turbulent exchange are given for the city of Omsk, an example. Possibilities of using approach to analyze the processes of pollution of urban atmosphere are discussed.
With satellite data on pollution of snow cover and data of meteorological observations, some fields of dust sedimentation from high chimneys of the Iskitim cement plant are studied. In the absence of snowfalls, a possibility to analyze of the areas of pollution, which are formed in time intervals from several days to several weeks in the vicinities of industrial enterprises, is shown.
