Details of Matraville Plume Plotter

This page should be read in conjunction with How Plume Plotter Works. It provides more details specific to the Matraville version of Plume Plotter.

Stacks and buildings

The proposed incinerator's building layout is not known, so it is (unrealistically) assumed that there are no buildings near the stack. The presence of such buildings would cause building downwash and increase ground-level concentrations.

Stack measurements

Apart from the stack location, these are estimated from the proposed incinerator's annual throughput (200000 tonnes per annum):

The following values are used for albedo, Bowen ratio and roughness length:


The emission rates of pollutants are estimated from the proposed incinerator's annual throughput (200000 tonnes per annum), using the EU IED limits on pollutant concentrations:

PollutantEmission rate
per second
Oxides of nitrogen8.909 g
Particulates445.5 mg
TOC445.5 mg
Hydrogen chloride445.5 mg
Hydrogen flouride44.55 mg
Sulphur dioxide2.227 g
Carbon monoxide2.227 g
Cadmium and thallium2.227 mg
Mercury2.227 mg
Other metals22.27 mg
Dioxins and furans4.455 ng

Background levels

The background levels of pollutants used are not very local: they are taken from the 2016 proposal for the Eastern Creek incinerator in Western Sydney:

concentration per m3
Oxides of nitrogen23 μg
Particulates19 μg
Hydrogen chlorideN/A
Hydrogen flourideN/A
Sulphur dioxide3 μg
Carbon monoxideN/A
Cadmium and thalliumN/A
Other metalsN/A
Dioxins and furansN/A

Weather data

Weather data is taken from METAR reports from a local airport: Sydney International.

Upper air data is the latest reported by the Moree Mo upper air station.
