AbstractThis program will provide an improved understanding of the effects of atmospheric moisture on hazardous material and define methods to better model these effects in the DTRA HPAC model. The work will evaluate the interaction of moisture and hazardous material in the HPAC model based on two levels of coupling the transport equations for hazardous material and moisture. These evaluations will be combined with a non-dimensional assessment of the transport equations to determine the most important effects. An attempt will be made to bound the uncertainty in hazardous material fallout due to the incomplete coupling of the moisture and hazardous material transport equations. Atmospheric moisture fields from satellite and radar measurements and/or the results of numeric weather predictions will be used in the evaluations. A strategy will be developed to implement the use of externally generated moisture fields in HPAC. This will include reformatting the data for compatibility with HPAC and interpolating the data positions to correspond to the HPAC computational grid. The strategy will provide an ability to use real time or nearly real time moisture fields.
