This page should be read in conjunction with How Plume Plotter Works. It provides more details specific to the Redcar version of Plume Plotter.
Building measurements are taken from the drawings in the incinerator's planning application.
The image below 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. Albedo and roughness length values are taken from [1]:

Weather data is taken from METAR reports from a local airport: Teesside International.
Upper air data is the latest reported by the Albemarle upper air station.
