This page should be read in conjunction with How Plume Plotter Works. It provides more details specific to the Whistleberry version of Plume Plotter.
The incinerator building is much shorter than the stack and not expected to affect the plume, but the main building has nevertheless been included in our model. Building measurements are taken from the site layout which is also included in .
This image shows the layout of the stack and buildings modelled:
All of these are taken from  except the stack location which is not stated but was calculated from the site layout included in :
The following values are used for albedo, Bowen ratio and roughness length. None of these are specified in  or :
The emission rates of pollutants are taken from . These are:
|Oxides of nitrogen||7.56 g|
|Hydrogen chloride||378 mg|
|Hydrogen flouride||37.8 mg|
|Carbon monoxide||1.89 g|
|Sulphur dioxide||1.89 g|
|Cadmium and thallium||1.89 mg|
|Other metals||18.9 mg|
|Dioxins and furans||3.78 ng|
The background levels of pollutants are taken from . These are:
concentration per m3
|Oxides of nitrogen||14.7 μg|
|Hydrogen chloride||240 ng|
|Hydrogen flouride||3 μg|
|Carbon monoxide||150 μg|
|Sulphur dioxide||2.1 μg|
|Cadmium and thallium||300 pg|
|Other metals||54.53 ng|
|Dioxins and furans||28.8 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 and the secondary weather station is .
Upper air data is the latest reported by the Albemarle upper air station.
