7.Examples of good practice
In this section we present a number of examples provided to us by the following parties:
Jenny Stocker, CERC
Model verification exercise
Pollutants: NOx, NO2, O3, PM10, PM2.5, SO2 interested in annual averages and model performance statistics, e.g. correlation, standard deviation. Also plots of results, such as scatter plots, bar-charts, Q-Q plots.
Advanced three dimensional quasi-Gaussian model calculating concentrations hour by hour, nested within a straight line Lagrangian trajectory model which is used to calculate background concentrations approaching the area of interest. Road, industrial and residual sources can be modelled in detail using a variety of options such as terrain, buildings, street canyons and chemistry.
Input:Emissions data, such as a grid of emissions over modelling domain, with detailed road and industrial source emissions; hourly meteorological data and measured/modelled background concentrations in text file format; text files containing the variation of terrain heights and roughness lengths over the domain; source parameters such as widths and street canyon geometry for roads, stack heights for industrial sources; and building dimensions.
Output:Concentrations may be output in an hourly average format over a 2D or 3D grid of receptor points and/or at specified receptor points.
