Vehicle emission remote sensing roadshow
Dr David Carslaw, Principal Air Quality Scientist at King’s College London, has started a six-week programme of roadside vehicle emissions testing in cities across England. Equipment supplied by the University of Denver will be used to shine an infrared beam across roads to detect the exact breakdown of exhaust gases.
Dr Carslaw and research student Max Priestman started their work in Oxford and were featured on BBC South's TV news.
After Oxford the team will move on to London where the focus will be on the quantification of nitrogen oxides and ammonia from Transport for London’s new bus retrofits. These new models use an optimised Selective Catalytic Reduction (SCR) system to reduce air pollution.
The final sampling campaign will be in Leeds where the focus will be controlled testing, where individual new technology vehicles are tested numerous times under different conditions. The research is supported by the UK government’s Department for Environment, Food and Rural Affairs (Defra). This latest study follows a similar project on vehicle emission remote sensing in London last year.
Results from the study are expected towards the end of the year.
