PROBLEM TO BE SOLVED: To provide a technique for predicting environmental concentrations, when the forms of various emission sources are combined.;SOLUTION: A concentration distribution of the form (a spot source, an area source, and a line source) of each emission source is computed in S102-S104. The coordinates of each computed concentration distribution are transformed so as to compute a synthesized concentration distribution, acquired by synthesizing each concentration distribution at common coordinates in S106. Computed synthesis concentration distributions and observed values are processed so as to make the concentration distributions smooth, through the use of an advection-diffusion computation technique to compute a combined smooth concentration distribution in S107. A smooth concentration distribution of the form of each emission source is computed, on the basis of the combined smooth concentration distribution to compute the difference between a computed smooth concentration distribution of the form of each emission source and a concentration distribution prior to the transform process as a correction value in S108-S109. Computations are repeated, until the absolute values of all the correction values become less than a preset threshold (S110) and environmental concentrations (S112) are predicted.;COPYRIGHT: (C)2011,JPO&INPIT
