This page provides information on a tool designed for validation of results from the OSPM model (Operational Street Pollution Model). The tool is suitable for exploratory analysis of OSPM model performance.
The tool has the form of an Excel spreadsheet with macros, and it can produce a range of graphs and tables, which can help to verify whether the model yields the right result for the right reason.
The following material is available:
The following excerpt from the conference paper outlines how the tool can be used:
The validation tool examines trends in observed and modelled annual averages, and produces scatter plots for hourly, diurnal and monthly mean concentrations of NOx, NO2, O3, PM10, PM2.5 as well as plots displaying concentrations as function of wind direction. In the present paper examples are presented of how this tool facilitates the exploratory data analysis of observations and model results. Further is demonstrated how the tool enables the user to identify both shortcomings in the model parameterisation and possible errors and uncertainties in the measured data.
The tool in the package includes some sample data (2 years of hourly data for one street monitoring station and a background station, and 17 years of yearly summarised data for the two stations). You can use to tool with these sample data to gain an impression of how it works.
If you wish to use the tool with your own data, the requirements are as follows
