New 'pollution radar' developed to provide unprecedented picture of urban smog
Date:3/9/2009

h Organization has estimated that 2.4 million people die each year from causes directly attributable to air pollution, with 1.5 million of these attributable to indoor air pollution. Population exposure to increased levels of gases and particulates requires action by public authorities at the national, regional and international levels.

"Measurements of atmospheric composition and quality are important to both the long term monitoring and control of human and naturally occurring emissions and the shorter term effects on human health. There is an increasing need for data to be collected, on a long term basis, in more detail, over larger areas and with higher levels of consistency with the CEOI playing a key role in meeting this challenge."

During 2009 two new CompAQS instruments are being constructed and configured for use as a ground-based Differential Optical Absorption Spectroscopy (DOAS) system by the University of Leicester, in collaboration with partners at Surrey Satellite Technology Ltd. These instruments will operate in the visible wavelength region to enable virtually real-time, 3D maps of atmospheric gases such as nitrogen dioxide to be constructed with five-minute time resolution. This is achieved by the simultaneous analysis of scattered solar UV/Visible radiation from multiple instruments and multi viewing geometries, giving an unprecedented level of information on the dynamics and composition of the urban environment.

The CityScan instrument will have significant advantages over currently available air quality monitors providing a continuous monitoring technique for an entire urban area. Each system is envisaged to provide coverage of areas of some 25 km2 and to undertake real-time monitoring of nitrogen dioxide and aerosol at a spatial resolution of 50m. Effectively, acting like a pollution radar.

CityScan will enable the collection of unique air quality monitoring datasets with the potential to open up new ar
