Effective source technique for express-estimation of total power of a gas impurity emission in the atmosphere.
The method of express estimation of total power of a gas impurity emitted in the atmosphere by a group of continuous point sources is presented. The method is based on the trace measurements of integral pollutant concentration and corresponding replacement of real group of sources by a virtual effective surface source that encompasses whole emission area. The Gaussian plume model is used to describe atmospheric dispersion of each independent source. The estimation of the relative error of the method depending on the dispersion between emission power of individual sources, the spatial configuration of sources within emitting area, the turbulent condition of atmosphere, and effective height of emissions is carried out.
