Urban particle emission rates related to source characteristics and meteorology measured in and above the centre of the city of Manchester (UK)

Over 2 months in summer 2005 extensive measurements have been made in central Manchester covering particle number concentrations, size distributions (from 3 nm to 32 mm), composition (by online aerosol mass spectrometry) and turbulent fluxes across 4 traffic-influenced locations. This data is intended to characterise the aerosol being emitted from the city centre as a whole. The total particle number flux has been concurrently measured at a height of 90 m above street level in the centre of the ~1 km2 area covered by the experimental campaign using the eddy covariance technique. As well as extensive particle measurements, traffic data has been recorded and data from a network of sonic anemometers across the sites provided a comprehensive dataset, which will be related to variations in the measured urban particle emission rate.
