This page should be read in conjunction with How Plume Plotter Works. It provides more details specific to the Carlisle version of Plume Plotter.
Building measurements are taken from [1]. This image shows the layout of the stack and buildings modelled. North is at the top; colours and numbers indicate the height of the buildings and the stack.
These are taken from [1]:
The following values are used for albedo, Bowen ratio and roughness length. Roughness length is as specified in [1]:
