ADMS 3
The ADMS 3 (Atmospheric Dispersion Modelling System) is an advanced
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.[2]
Features and capabilities of the ADMS 3
The model includes
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.[2]
The model is capable of simulating
Pasquill class.[2]
ADMS 3 can simultaneously model up to 100
emission sources, of which:[2]
- 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.[3]
