Reliability of current U.S. modeling of atmospheric plumes questioned



The deficiencies of atmospheric modeling used to determine the dispersion of chemical, radiological, or biological plumes came under fire during a 2 June hearing in the U.S. House of Representatives. Several members of Congress said that current modeling efforts provide inadequate information to assess plumes that could result from a terrorist incident, warfare, or some other cause.

Much of the hearing, held by the House Subcommittee on National Security, Emerging Threats, and International Relations, focused on two reports released that day: one by the U.S. National Academy of Sciences (NAS), and the other by the U.S. General Accounting Office (GAO).
