This page should be read in conjunction with How Plume Plotter Works. It provides more details specific to the Rookery 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. The value of roughness length is as specified in :
The emission rates of pollutants are taken from . These are:
|Oxides of nitrogen||25.86 g|
|Sulphur dioxide||6.465 g|
|Carbon monoxide||6.465 g|
|Hydrogen chloride||1.293 g|
|Hydrogen flouride||129.3 mg|
|Cadmium and thallium||6.465 mg|
|Other metals||64.65 mg|
|Dioxins and furans||12.93 ng|
The background levels of pollutants are taken from . These are:
concentration per m3
|Oxides of nitrogen||23.55 μg|
|Sulphur dioxide||4.26 μg|
|Carbon monoxide||332 μg|
|Hydrogen chloride||710 ng|
|Hydrogen flouride||2.35 μg|
|Cadmium and thallium||120 pg|
|Other metals||18.11 ng|
|Dioxins and furans||33 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 Herstmonceux upper air station.
