Nitrogen dioxide (NO2): NO2 is produced in high temperature combustion processes and chemical reactions in the atmosphere. Road transport is responsible for 60 per cent of emissions of NOx (the pollutant that causes NO2) in London. It can affect the lungs and airways when exposed over long periods or at high concentrations over a short period.

The movie about depicts our visualisation at CASA of N02 in London, created in association with the Environmental Research Group at Kings College London. The movie was created to illustrate the use of the Virtual London model to gain a sense of location and place when communicating geo-specific information.

Moving data into the third dimension can however be counter productive. While the movie clearly communicates areas of high N02 concentration it also falsely suggests to some that the air is clear above the peaks – which is course it is not as N02 is measured from a set height. Although in general we would argue that it is more successful than the standard 2D map in getting the spatial information across…(?)
