In low-wind stable conditions, source reconstruction becomes sensitive to the height of the release and receptors measuring the concentrations. Therefore, an inversion technique, based on theory of renormalization, is proposed to identify the height of the release along with its location on the ground and emission rate in the atmosphere. The technique utilizes the information derived from the geometry of the monitoring networks. The retrieval algorithm is evaluated with real observations taken from Idaho diffusion experiment, conducted in low wind stable conditions.
