Pollution Rose Plots
ERG added the ability to plot the level of pollution by the direction of the
wind at the time.
This tool helps us to understand how any local sources may affect
any readings seen, and is a great help in pollution analysis. The website allows
users to select the most appropriate wind data, based on how well it covers the
dates in question, the quality of the wind data and the distance for the pollution
sites the wind data was measured.
This is needed because wind data varies greatly
in its quality, and some wind measurements are valid for local sites only. The tool
keeps ther user informed about what data is being selected, and warns of any problems
with the data.
This project produces very nice images, but we have also worked hard
to ensure that the data is correct and that the tool is useful.
