The European Tracer Experiment (ETEX) was an atmospheric dispersion modeling study conducted in late 1994. ETEX involved two releases of inert tracer gases, real-time predictions of the motion of the plumes by participating modeling centers, detection of the gas plumes as they passed a large network of sampler locations across most of Europe, and comparison of the model predictions with the sampler values. The Atmospheric Release Advisory Capability (ARAC) at the Lawrence Livermore National Laboratory was one of the modeling centers that participated in ETEX. This paper discusses the latest evaluations of ARAC`s ETEX predictions and the improvements to the ARAC system resulting from ETEX participation. ARAC has improved by many successive changes over its 20-yr history, driven in many cases by the results of model evaluations such as ETEX. Thus, our prime purpose in participating was to find areas for further improvement. Another goal was to produce reasonably accurate predictions within the specified time limit.
