Automated source parameter and low level wind estimation for atmospheric transport and dispersion applications
This VIRSA STE algorithm has been tested on field trials including FUSION Field Trial 2007 (FFT07), a field program funded by the Defense Threat Reduction Agency (DTRA) to test STE algorithms. VIRSA testing with FFT07 yielded positive results; however, the field trial provides a limited number of environmental and operational scenarios that the algorithm may face. To extend the STE test space we developed a number of synthetic, physically realistic transport and dispersion realizations using the Large Eddy Simulation capability. Using these synthetic data sets in conjunction with FFT07 we have conducted a more rigorous examination that includes a broader variety of plume dispersion scenarios with varying travel distances, sensor configurations, and plume detection methods. In addition, the limits of model performance were investigated.
