Christele Donadini from Astrium Services said: "Monitoring and controlling greenhouse gas (GHG) emissions is crucial at international, national and major city level, to both reduce the level of polluting emissions and to promote the uptake of green, low carbon technologies. This will become even more important as growing populations will make our future cities the primary contribution to man-made global climate change, and countries will need to implement robust strategies to report and reduce their carbon footprint."
As part of a pilot scheme for the new service, NPL, on behalf of Astrium, set up four sensors at elevated points across London to measure the concentrations of carbon dioxide and methane in the city's air.
The project combined these ground measurements from a network of four sensors with airborne measurements and space-borne data collection. On top of that, The Astrium Bus, a converted London bus, which housed a mobile GHG sensor, was driven around a fixed London route every day to detect GHG concentrations at road level.
The bus combined the various measurements to produce a real-time cityscape video of carbon dioxide and methane concentrations around Central London. This produced 3D visualisations of modelled emission sources over London, the UK and the world, showing how natural sources and sinks of carbon dioxide compared with man-made emissions over a cycle of days and weeks.
