The ADMS 3 (Atmospheric Dispersion Modelling System) is an advanced atmospheric pollution dispersion model for calculating concentrations of atmospheric pollutants emitted both continuously from point, line, volume and area sources, or intermittently from point sources. It was developed by Cambridge Environmental Research Consultants (CERC) of the UK in collaboration with the UK Meteorological Office, National Power plc (now INNOGY Holdings plc) and the University of Surrey. The first version of ADMS was released in 1993. The version of the ADMS model discussed on this page is version 3 and was released in February 1999. It runs on Microsoft Windows. The current release, ADMS 5 Service Pack 1, was released in April 2013 with a number of additional features.The CERC web site pages about ADMS

The system also includes a meteorological data input preprocessor. The model is capable of simulating passive or buoyant continuous plumes as well as short duration puff releases. It characterizes the

depth and the Monin-Obukhov length, rather the single parameter Pasquill class. ADMS 3 can simultaneously model up to 100 emission sources, of which: * up to 100 may be point or jet sources * up to 6 may be line, area or volume sources * 1 may be a line source The latest version (ADMS 5) allows up to 300 sources. Within that limit, up to 300 point sources, 30 line sources, 30 area sources and 30 volume sources may be modelled. The performance of the model has been evaluated against various measured dispersion data sets.Hanna, Steven R et al.
