Project leader Dr Roland Leigh, of the Earth Observation Science group, explains to ITV News Central reporter Chris Halpin how the specially adapted Spectrometer mapped air quality around Leicester.
The device gave a reading for Nitrogen Dioxide (NO2) levels between the ground and the plane - which was flying at around 900m.
Each reading corresponds to an area of 6 metres by 100 metres at ground level.
