odelling of air pollution around busy urban areas such as airports is a complex task. Ground stations for monitoring air quality and compliance reporting are usually limited in number, because of cost, to a few strategic locations. More recently given the advances in sensors, electronics and communication technologies it is now possible to design and build networked sensor nodes at a fraction of the cost of traditional systems. These breakthroughs in technology make it possible to implement large-scale sensor networks in city environments. A team led by Professor Rod Jones at the University of Cambridge, funded by NERC, is now doing just that for Heathrow Airport to better understand and develop sophisticated computer models for air quality in the vicinity of this busy international airport. to learn more click on the image or the title.
