The Atmospheric Dispersion Modelling Liaison Committee (ADMLC) is composed of representatives from government departments, agencies (predominantly but not exclusively from the UK) and private consultancies. The ADMLC's main aim is to review current understanding of atmospheric dispersion and related phenomena for application primarily in the authorization or licensing of pollutant emissions to the atmosphere from industrial, commercial or institutional sites.
The ADMLC is primarily concerned with atmospheric pollutant discharges from regulated emission sites and other fixed sources. Their review and study interests include routine discharges as well as accidental releases or releases cause by operational upsets. Their interests also include modelling dispersion at all scales from on-site short range (including dispersion modelling indoors) to long range distances. The ADMLC does not normally get involved with pollutant emissions from roadway traffic or other non-fixed sources. Nor does it get involved with air pollution topics such as acid rain and ozone formation.
In 1977, a meeting of representatives from UK government departments, utilities and research organisations was held to discuss atmospheric dispersion calculation methods for radioactive releases. Those present agreed on the need for a review of recent developments in atmospheric dispersion modelling and formed an informal Steering Committee, which operated for a number of years. That Steering Committee subsequently became the Atmospheric Dispersion Modelling Liaison Committee in 1995.
Although the ADMLC was initially formed to consider primarily radioactive releases from the nuclear industry, it has expanded its range of interests and its membership to more fully reflect the needs of industrial and regulatory organisations.
As listed on the ADMLC's web site, the membership of the ADMLC includes the following entities:
ADMLC facilitates the exchange of ideas and highlights where there are gaps in knowledge. It tries to provide guidance to, and to endorse good practice in, the dispersion modelling community. The ADMLC has hosted workshops and welcomes ideas for joint meetings or joint workshops with other organisations.
The ADMLC members pay an annual subscription which is used to fund reviews on topics agreed on by the members. Reviews already funded by ADMLC include:
