In general, an estimation of spatial distribution of air pollutant concentration has been done by using physical models. In this paper, however, the estimation by a non-physical model upon observed data is developed and an example of its application to estimation of spatial distribution of NO_x (NO+NO_2) concentration in Tokyo metropolitan area is presented. The method of estimation presented here is a weighted averaging method, where weights are estimated by using two statistical characteristics of variation of the concentration among monitoring stations. One of the statistical characteristics is that a relation of the concentration between arbitrary two stations is expressed as an exponential function of the interdistance, r=exp[-d/L], where r is correlation coefficient between two stations, d the interdistance and L a constant. The other is that a relation between mean μ and standard deviation σ of the concentration at an arbitrary station is expressed as σ=αμ^β, where α, β are constants.
