Monitoring of urban pollution has been largely dependent upon relatively small numbers of stationary monitoring locations. Although there is certainly value in being able to provide high-quality data for a continuous period from a fixed monitoring station, these do not…
Urban airborne releases are difficult to model as the city itself is not a flat land surface. Urban structure, including streets, intersections, traffic and local meteorology, will play a major part in determining how material released to the atmosphere will…
Urban dispersion research has to deal with a fundamental dilemma. On the one hand, it needs to draw on field evidence, which is obtained in the real world in which all components of the urban system – buildings, people, traffic,…
City pollution stories mostly focus on emissions: traffic, vehicles, fuel, industrial sources and background pollution. These are relevant, but they do not tell the whole story, because once emissions enter the city, they are subject to transport, recirculation, dilution and…
We can’t simply predict air pollution at street level based on the volume of pollution emitted. In a city, this depends on the buildings, traffic, wind, turbulence, street configuration and people’s movement through urban space. This is why street-level air…
