Quantifying air quality in Cambridge by combining sensors with computer modelling
CERC have been collaborating on a project to study ambient air quality across Cambridge using a large number of sensor nodes and computer modelling. 20 AQMesh sensor pods have been placed at key points around Cambridge (see top picture), measuring air quality in near real time. Comparisons against a reference instrument give very encouraging results, as shown in a paper recently presented by Professor Rod Jones of the University of Cambridge.
The next steps are to compare collected AQMesh data with ADMS-Urban modelled data for the same area and then use the real-time AQMesh data to improve CERC's air quality forecasts for Cambridge. This would demonstrate the potential to improve services such as the Mayor of London's public notifications during high pollution episodes, which are displayed at Tube stations, bus stops (see bottom picture), river piers and on digital signs along major roads, and which use a three-day ahead air pollution forecast provided by CERC's airTEXT forecasts for London.
