Integration of AMS and ERDS Measurement Data into NARAC Dispersion Models. FY05 Technology Integration Project Final Report

摘要

Staff from Lawrence Livermore National Laboratory (LLNL), Bechtel Nevada Remote Sensing Laboratory (RSL), and Sandia National Laboratory (SNL) completed the proposed work for the Technology Integration Project titled Integration of AMS and ERDS Measurement Data into NARAC Dispersion Models. The objectives of this project were to develop software to convert Aerial Measurement Survey (AMS) and Emergency Response Data System (ERDS) field measurement data into a standard electronic format for transmission to the National Atmospheric Release Advisory Center (NARAC), and to streamline aspects of the NARAC operational atmospheric dispersion modeling system to quickly process these data for use in generating consequence calculations based on refined, field measurement-based estimates of the source strength. Although NARAC continues to develop and maintain a state-of-the-art atmospheric dispersion modeling system, model predictions are constrained by the availability of information to properly characterize the source term. During an actual atmospheric release, very little may be known initially about the source material properties, amount, or release time and location. Downwind measurements often provide the best information about the scope and nature of the release. The timely integration of field measurement data with model calculations is an obvious approach toward improving the model consequence predictions.
