Abstract

The ability to forecast the transport and diffusion of airborne contaminants over long distances is vital when responding to nuclear emergencies. Atmospheric models used in such emergency response applications must be able to include the effects of the evolving synoptic weather systems in a timely manner. The European Tracer EXperiment (ETEX), conducted in October and November 1994, is designed to evaluate the performance of such models. In addition to the tracer experiments, concurrent real-time modeling exercises were conducted by some 24 organizations world-wide, including the Savannah River Technology Center (SRTC) of the U.S. Department of Energy`s Savannah River Site. This paper describes the forecast results obtained by atmospheric modelers at SRTC in applying an advanced three-dimensional modeling system to forecast tracer transport and diffusion during ETEX. Forecast results from the first of two tracer experiments are presented in this preprint paper. Data for the tracer gas concentrations is not yet available; however, surface and sounding data are available from the time periods of the releases. This paper will focus on the evaluation of the forecasts in light of the surface wind data, and relate the forecast evaluations to the differences in the tracer gas dispersion predicted using these forecasts.

Application of a three-dimensional prognostic model during the ETEX real-time modeling exercise: Evaluation of results

Conference Griggs, D

Increases in computing capabilities and ready access to large-scale model output make it possible to employ advanced three-dimensional prognostic models to forecast the long-range transport of toxic or radioactive gases for emergency response. The Savannah River Technology Center (SRTC) of the U.S. Department of Energy`s Savannah River Site demonstrated this during the European Tracer EXperiment (ETEX). ETEX, conducted in the Fall of 1994, provided an opportunity to evaluate the performance of models for long-range atmospheric pollutant transport and dispersion. A comparison of SRTC forecast results for the first ETEX experiment with measured surface tracer gas concentrations shows that the predictedmore »« less

Long-range mesoscale modeling of pollutant transport for the European Tracer EXperiment (ETEX)

Conference Fast, J; Griggs, D; Addis, R

The European Tracer EXperiment (ETEX). The ETEX program involves two tracer experiments each comprising from distinct elements: (a) long-range atmospheric tracer release, sampling, and analysis; (b) real-time model operation and evaluation; and (c) post-release model operation and evaluation. The experiments consist of the release of a non-buoyant tracer from a location in western Europe and sampling of the atmospheric concentration by a network of about 200 stations located in 17 countries. Twenty-three institutions from 19 countries are expected to participate in the real-time modeling program including the Savannah River Technology Center (SRTC) of the US Department of Energy`s Savannah Rivermore »« less

Atmospheric Prognostic and Dispersion Model Design for Use in the European ENSEMBLE Modeling Exercises

Technical Report Buckley, R

Many atmospheric transport and dispersion models now exist to provide consequence assessment during emergency response to near-field releases. One way of estimating the uncertainty for a given forecast is to statistically analyze an ensemble of results from several models. This paper discusses the involvement of the Savannah River Technology Center (SRTC) in a European Union program, ENSEMBLE. This program utilizes an internet-based system to ingest transport results from numerous modeling agencies. SRTC uses a prognostic atmospheric numerical model to provide three-dimensional and time-varying meteorology as input to a stochastic Lagrangian particle model. This modeling system provides better resolution than ismore »« less
