Abstract

We recently developed the method for identification of location, start time, duration and release rate of an unknown short-duration source of airborne pollution in urban environment. The method has been integrated in the ADREA-HF CFD code and the testing has been carried out by performing series of source inversion runs using the data of 200 individual realizations of the puff releases as obtained in the wind tunnel CUTE experiment. The robustness of the developed source inversion approach was thus demonstrated. The developed algorithm could be potentially applied in real-time emergency response systems dealing with the releases of toxic hazardous substances.
