The SELCHP plume plotter shows a prediction of the current amount of air pollution (at ground level) caused by emissions from the incinerator in Landmann Way, Lewisham.

Plume Plotter predicts this fallout using AERMOD, which is one of the most widely used modelling systems for air pollution. It uses the latest local weather conditions and upper air data, which are obtained in real time. Plume Plotter does not use real-time information about the incinerator's emissions. Instead, it assumes that it is operating continuously (8760 hours per year) and emitting pollutants at a constant rate. The emission rates assumed are the average actual emission rates for a recent year, as measured and reported to the Environment Agency.

The other parameters (e.g. emission velocity and temperature) used were obtained from a recent SAHSU publication.

Plume Plotter's model takes account of the real terrain in the vicinity of the incinerator and the shape of the incinerator buildings. Building dimensions were obtained from a 2009 planning application and from aerial photographs.
