Details of Ford Plume Plotter

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

Stacks and buildings

Building measurements are taken from [1]. The image below shows the layout of the stacks and buildings modelled. North is at the top; colours and numbers indicate the height of the buildings and the stack:

Stack measurements

All of these are taken from [1]:

The following values are used for albedo, Bowen ratio and roughness length. Roughness length is as specified in [1]:
