Abstract

A statistical method based on adjustments of spatial source oriented structure functions to observed concentration values is presented. Hourly spatial structure functions are determined by hourly source oriented model calculations based on a time dependent numerical algorithm on a km scale. Stationary Gaussian models are used to describe subgrid gradients in concentrations as a result of point and line sources in the area Parameters adjusting location and amplitude of source oriented structure functions and background concentrations to observed hourly concentration values are estimated on an hourly basis. The method is based on Bayesian statistical analysis and uses tentative apriori information about the uncertainties in source oriented model calculations in the area. The improvements in sp
