Details of Corby (Shelton) Plume Plotter

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

Stacks and buildings

Building measurements are taken from drawings in [2]. The orientation of the buildings is not shown on the plan, so it was assumed to be the same as that of the previously proposed incinerator: perpendicular to Shelton Road. The image below shows the layout of the stack and buildings modelled:

Stack measurements

All of these are taken from [1]. The two stacks are modelled as a single larger stack, because of their proximity.

The following values are used for albedo, Bowen ratio and roughness length. These are not specified in [1]:


The emission rates of pollutants are taken from [1]:

Weather data

Weather data is taken from METAR reports from a local airport: Wittering RAF.

Upper air data is the latest reported by the Nottingham upper air station.
