Accidental or deliberate release of Chemical, Biological, Radiological or Nuclear (CBRN) material can result in a toxic plume that is dispersed by wind. Accurate estimate of the dispersion of the toxic material is imperative for timely deployment of first responders and evacuation of populations in the path of the toxic plume. Research related to assimilating sensor data with model forecast for accurate forecasting of plume dispersion is ongoing in conjunction with the development of algorithms for the characterization of sources which can help cap the source of the release. Since the forecasting process is hobbled by inaccuracies in sensor measurements, model errors and errors in estimates of the wind field, a second project related to characterizing and propagating uncertainties through the dynamic system is currently being studied.
