Abstract

Optimization and management of ambient pollutant concentration measurements by dispersion modeling S. Heinz, R. Knoche, K. S chafer Fraunhofer Institut fur Atmosphdrische ABSTRACT Emission rates of difficult to access sources can be calculated by means of modified Gaussian dispersion theory. Here, a concept is developed for the optimization of such measurements. In particular, this method is well matched to the ability of optical remote sensing techniques to provide path-integrated concentration values and can be applied for distributed sources. Measurement configurations can be calculated which provide a maximal partitioning of the measured concentrations into the contributions of different sources. Moreover, measurement configurations can be found which are least sensitive with respect to the variations of model parameters used in Gaussian theory. To overcome application limits of the Gaussian method, Lagrangian modeling of turbulent diffusion can be used and con
