ON THE PROCEDURE FOR TAKING ACCOUNT OF THE ERRORS OF CONCENTRATION MEASUREMENTS IN SOLVING “INVERSE” PROBLEMS FOR ATMOSPHERIC ADMIXTURE DISPERSION

Dispersion of aerosol and gas pollutants in atmosphere is usually described by the problems of two types. The first one is a "direct" problem on determination of admixture concentration field by the known characteristics of the admixture source. The second one is an "inverse" problem on determination of type, coordinates, rate of a pollutant source and other applied characteristics of atmospheric diffusion by the information on the admixture concentration at a number of control points. Method for solving the inverse problem is based on the approach, founded by Marchuk (1982). The method involves solving an equation conjugated with the semi-empirical equation of turbulent diffusion. The measured values of the concentration of admixture, which are used in solving the "inverse" problems, as a rule, are scattered. Therefore the errors of concentration measurements have to be accounted for in the solution of practical tasks. The presented study is dedicated to consideration of approaches to the solution of the indicated problem.
