Multiscale Environmental Dispersion Over Complex Terrain The MEDOC Models.
Abstract
This report describes a capability called MEDOC which includes a suite of codes used for the assessment/ prediction of Multiscale Environmental Dispersion Over Complex Terrain. The codes which were originally developed by and for the nuclear power industry have been adapted under a program described in this report, to a broader range of problems involving chemical and biological, as well as nuclear, sources which are of concern to the U.S. Defense Nuclear Agency (DNA) and the national defense community. MEDOC can operate in either a prognostic or diagnostic mode, providing both the meteorological and the concentration transport/dispersion fields over a range of atmospheric scales from local (approx 10's of KM), to regional (approx 1OO's of KM). Alternate methodologies, from first principles based to more approximate, are provided to allow various degrees of fidelity and computational efficiency. Thus MEDOC provides appropriate models for a variety of applications such as guidance for local scale emergency response, forecasts for regional scale impacts, and future planning studies. The codes are operational on either a super computer (CRAY), or a workstation level platform (IBM RlSC16000), and have been installed on workstations where they are exercised by DNA personnel.
