DETERMINATION OF THE CHARACTERISTICS OF A SOURCE OF AEROSOL AND GAS ADMIXTURES IN ATMOSPHERIC BOUNDARY LAYER BY THE MEASURED VALUES OF CONCENTRATION. RESULTS OF TEST CALCULATIONS

The problems of the environment protection, connected with the diffusion of gas and aerosol admixtures in atmosphere can be divided into two groups. The first one contains "direct" problems, in which the pollutant concentration and other applied characteristics of atmospheric pollution must be determined by the information on the pollutant source. The second group contains "inverse" problems, in which the type, coordinates of a source and amount of emitted substance must be determined by the measured values of the pollutant concentration. The necessity of solving the "inverse" problems arises in connection with industrial emissions under technogenic accidents and other extreme situations. An efficient and stable method for solving the inverse problems based on the use of an equation conjugated with the semi-empirical equation of turbulent diffusion was developed by us before (Desyatkov et al., 1999, Sarmanaev et al., 2000). The idea of the use of conjugated equations for solving the problems of ecology was first suggested by Marchuk (1982). According to the method of Marchuk the determination of the Green function, which is a solution of the conjugated equation allows to avoid the multiple solving a "direct" problem in the iteration procedures that was conventionally used before when solving the "inverse" problems. The results of testing the method with the use of the theoretical and experimental data are given in the present work.
