Details of Loughborough Plume Plotter

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

Stacks and buildings

Building measurements are taken from [2]. This image shows the layout of the stack and buildings modelled. (Because of its strange shape, the single building has to be modelled as a number of flat-roofed polygonal buildings.) North is at the top; colours and numbers indicate the height of the buildings and the stack. Note that the highest building (35.1m high) has an even higher tier (45.7m) on top:

Stack measurements

The following values are used for albedo and Bowen ratio, while roughness length varies with wind direction. This is all as specified in [1]:
