This page should be read in conjunction with How Plume Plotter Works. It provides more details specific to the Corby version of Plume Plotter.
Building measurements are taken from . This image shows the layout of the stack and buildings modelled:
All of these are taken from :
The following values are used for albedo, Bowen ratio and roughness length. Roughness length is as specified in :
The emission rates of pollutants are taken from .
Unfortunately this document  is inconsistent: Table 6.1 states that the normalised flow rate is 14.327 μg/m3 but Table 6.2 shows it to be 7.34 μg/m3. We have (arbitrarily) assumed the higher value (14.327 μg/m3), which gives the following emission rates:
|Oxides of nitrogen||2.865 g|
|Sulphur dioxide||715 mg|
|Carbon monoxide||715 mg|
|Hydrogen chloride||143.1 mg|
|Hydrogen flouride||14.31 mg|
|Cadmium and thallium||715 μg|
|Other metals||7.15 mg|
|Dioxins and furans||1.431 ng|
The background levels of pollutants are taken from . These are:
concentration per m3
|Oxides of nitrogen||17.58 μg|
|Sulphur dioxide||2.26 μg|
|Carbon monoxide||269 μg|
|Hydrogen chloride||257 ng|
|Cadmium and thallium||90 pg|
|Other metals||9.231 ng|
|Dioxins and furans||2.49 fg|
Weather data is taken from METAR reports from a local airport: Wittering RAF.
Upper air data is the latest reported by the Nottingham upper air station.
