The ADMS 4 (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. [1] It was developed by Cambridge Environmental Research Consultants (CERC) of the UK in collaboration with the UK Meteorological Office, National Power plc[2] and the University of Surrey. The first version of ADMS was released in 1993 and the current version 4 was released in XXXX.[3]

Features and capabilities of the ADMS 4

The model includes algorithms which take into account: downwash effects of nearby buildings within the path of the dispersing pollution plume; effects of complex terrain; effects of coastline locations; wet deposition, gravitational settling and dry deposition; short term fluctuations in pollutant concentration; chemical reactions; radioactive decay and gamma-dose; pollution plume rise as a function of distance; jets and directional releases; averaging time ranging from very short to annual; and condensed plume visibility. The system also includes a meteorological data input preprocessor. [3]

The model is capable of simulating passive or buoyant continuous plumes as well as short duration puff releases. It characterizes the atmospheric turbulence by two parameters, the boundary layer depth and the Monin-Obukhov length, rather the single parameter Pasquill class. [3]

ADMS 4 can simultaneously model up to 100 emission sources, of which: [3]

  • 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 performance of the model has been evaluated against various measured dispersion data sets.
