Online Gaussian Dispersion Model - The Industrial Hygiene website consists of specialized online calculators for the occupational safety and health professional, including an online Gaussian dispersion model which is freely available for use by site visitors.
Online Version of SCREEN3 Model - This site is maintained by Pacific Environmental Services (with nationwide offices in the USA) who developed an online version of the U.S. EPA's SCREEN3 air dispersion model, which is freely available for use by any visitor to the site.
Online Version of Tox-Flam Model - Provides an online version of the Tox-Flam model for the use of any visitor to this website. Tox-Flam is a Gaussian dispersion model for releases of inert buoyant pollutants into a finite mixing layer of a user-specified height. The model was developed by Enviroware s.r.l.
Petersen & Kade - A firm located in Hamburg, Germany which markets air dispersion modeling software that meets the standards developed by: the Association of German Engineers (Verband Deutscher Ingenieure, or simply VDI), and by Germany's Federal air pollution control regulations (known as TA Luft).
SCIPUFF Model - The Titan Systems Corporation is a technology research and development group headquartered in San Diego, California and serving the U.S. defense and intelligence communities. The group has developed a Lagrangian puff dispersion model known as the SCIPUFF model.
SuperChems - SuperChems is a suite of models, developed by A.D. Little Inc. of Cambridge, Massachusetts, for consequence analysis and hazard modeling. It includes source term calculations, and dispersion, fire, and explosion models to quantify the hazard zones resulting from potentially toxic, flammable, and/or explosive releases from vessels, pipes, and liquid spills.
The ALOHA Model - The Areal Location of Hazardous Atmospheres model (ALOHA) was developed by the USA's National Oceanic and Atmospheric Administration (NOAA) for use in emergency responses to accidental releases of neutrally buoyant or heavier-than-air gases.
The AUSPLUME Model - Describes the AUSPLUME model developed in about 1986 by the Environmental Protection Authority of Victoria, Australia. The AUSPLUME model is an adaptation of the U.S. EPA's ISCST model (Industrial Source Complex Short Term model). Copies of the model can be purchased from the Victorian Environmental Protection Authority.
The AirQUIS Model - The Norwegian Institute for Air Research (NILU) has developed an Air Quality Information System (AirQUIS) having: an emission inventory data base; dispersion models; and a geographical information system (GIS) module. The dispersion models include a source oriented model (EPISODE), a puff-trajectory model, and models for traffic in street canyons and on roads (ROADAIR and CONTILENK).
The CADiP-3D Model - Simulates the dispersion of pollutants in complex topography, and was developed by the Thermodynamics Department of the University of Munich in Germany. It solves the equations for the conservation of energy, momentum and mass (for air and pollutants) and the ideal gas equation of state, by using the method of finite elements. The program works on unequally-spaced, three-dimensional rectangular grids.
The CAPARS System - Developed by AlphaTRAC, the Computer-Assisted Protective Action Recommendation System (CAPARS) provides plume extent, weather, hazard, and related information needed to support all levels of emergency management and response to an accidental release of hazardous gas. AlphaTRAC is located in Westminster, Colorado, USA.
The DEGADIS model - Dr. Tom Spicer and Dr. Jerry Havens of the University of Arkansas developed this model (for the U.S. Coast Guard and the Gas Research Institute) primarily for simulating the dispersion of denser-than-air flammable gases. The U.S. EPA later extended DEGADIS for dispersion modeling of vertical jets. Implementation of DEGADIS on personal computers was sponsored by the Gas Research Institute and the American Petroleum Institute.
The DREAM Model - The Danish Rimpuff and Eulerian Accidental release Model (DREAM), developed by the National Environmental Research Institute (NERI) of Denmark, is a high-resolution, three-dimensional tracer model for short and large scale atmospheric transport, dispersion, and deposition (wet and dry) of radioactive air pollution from a single strong source.
The EcoSense Model - An environmental impact model developed at the University of Stuttgart for the ExternE project of the European Union and other European nations. It assesses the environmental impacts and resulting external costs from electricity generation plants. It uses local or regional inputs from the EUROGRID database, and includes two air dispersion models.
The FLACS Model - FLACS (FLame ACceleration Simulator) is an advanced tool for the modeling of ventilation, gas dispersion, vapour cloud explosions and blast in complex process areas.
The GAMUT Model - The Global Atmospheric Multi-Layer Transport Model (GAMUT) is a modeling system for tracking and predicting the transport and diffusion of gaseous plumes in the atmosphere. It was developed and is offered by Ensco Inc., a nation-wide research and development company headquartered in Springfield, Virginia.
The Indic-Airviro System - The Swedish Meteorological and Hydrological Institute (SMHI) developed a dispersion modeling system with modules for: receiving input data from monitoring stations; an emission data base; and dispersion modeling. The dispersion module has a Gaussian model for small-scale applications, a grid model for large-scale regional applications, a street canyon model for emission sources surrounded by buildings, and a dense gas module.
The LASAT model - Developed by Janicke Consulting (located in Danum, Germany), the Lagrangian Simulation of Aerosol Transport (LASAT) model utilizes stochastic processes to simulate numerically the transport and turbulent diffusion of a group of representative particles. LASAT has a preprocessor which calculates the meteorological profiles and three-dimensional wind fields required for the simulations.
The MIDAS Models - Dispersion models, offered by PLG Inc. (located in Bethesda, Maryland), for routine and accidental airborne releases of hazardous materials. Versions available for: industrial releases of hazardous chemicals; nuclear facility radioactive releases; and response to chemical or biological releases by terrorists. Built-in dense gas and evaporation plume models. Real-time displays of the dispersing plume on site-specific maps.
The OML Model - A Gaussian plume model developed by Denmark's National Environmental Research Institute (NERI) that is recommended for environmental impact assessments of any planned new industrial sources. The model can be used at distances up to 20 km for high or low sources, one or more point sources, or area sources. It is not suitable for complex terrain and it requires input data on emissions and meteorology on an hourly basis.
