Abstract:

This document describes a prototype of an inversion method to reconstruct the unknown atmospheric release parameters, including hiding the release location and strength, and associated concentration field. The inversion method is based on the analysis of the data collected from wind, chemicalbiological sensors. A combined process of backward trajectory and Bayesian inference is used for the inversion. The retrieved atmospheric release location and strength by this method are the optimal estimations of the physical parameters. A simple test case is used to demonstrate the accuracy and application of the inversion method.
