This page should be read in conjunction with How Plume Plotter Works. It provides more details specific to the Smiths (Glos) version of Plume Plotter.
Building measurements are taken from drawings including . This image shows the layout of the stack and buildings modelled:
All of these are taken from  and , except stack location which is not stated but was deduced from the building plans and aerial photos:
The following values are used for albedo, Bowen ratio and roughness length. These are not specified in  or , but the roughness length was taken from the planning application for the Gloucestershire (Javelin Park) incinerator:
The emission rates of pollutants are taken from  and :
|Oxides of nitrogen||595 mg|
|Sulphur dioxide||425 mg|
|Carbon monoxide||425 mg|
|Hydrogen chloride||85 mg|
|Hydrogen flouride||8.5 mg|
|Cadmium and thallium||425 μg|
|Other metals||4.25 mg|
|Dioxins and furans||850 pg|
The background levels of pollutants are as used for the Gloucestershire (Javelin Park) incinerator. These are:
concentration per m3
|Oxides of nitrogen||15.3 μg|
|Sulphur dioxide||2.6 μg|
|Carbon monoxide||324 μg|
|Hydrogen chloride||2.35 μg|
|Hydrogen flouride||560 ng|
|Cadmium and thallium||430 pg|
|Other metals||20.75 ng|
|Dioxins and furans||44.1 fg|
Wind speed, wind direction, temperature, pressure, and solar radiation are the latest values reported by one of two weather stations. If a value is not available from the primary weather station it is obtained from the secondary weather station. (Some weather stations do not measure solar radiation at all.) The primary weather station is IGLOUCES43 and the secondary weather station is IGLOUCES6.
Upper air data is the latest reported by the Nottingham upper air station.
