Lawrence Livermore

National Laboratory


The Office of the Special Assistant for Gulf War Illnesses released an information paper on February 25, 2000, "The Use of Modeling and Simulation in the Planning of Attacks on Iraqi Chemical and Biological Warfare Targets." This information paper, in part, discusses a newspaper article written after the US Air Force released a Lawrence Livermore National Laboratory Memo for Record, "Atmospheric Release Advisory Capability (ARAC) Calculations for USAF TAC/IN," in response to a Freedom of Information Act request in 1997. As discussed in the newspaper article, it was believed that graphic representations that accompanied the Livermore memo represented the possible dispersion of chemical warfare agents. These graphics did not depict the dispersion of chemical agents. The graphics accompanying the memo released in response to the Freedom of Information Act request actually represented the results of a nominal attack on a nuclear target from an unrelated modeling project. The Livermore memo, which generically described the Laboratory�s capability to model a dispersion of chemical agents in the atmosphere did not use any specific intelligence or targeting data and was not a prediction of the results of bombing actual Iraqi chemical weapon storage sites. The correct graphics, which should have accompanied Livermore�s memo, were obtained by representatives of the Office of the Special Assistant for Gulf War Illnesses. The Laboratory�s capability is shown in the graphic representation of dispersion plumes produced on September 14, 1990.
