2015/12/3
The aim of this study is to explore the relationship between, transport, land-use and air quality and mapping of air pollutants by means of spatial information sciences, which would provide useful inf...
The promise of Beijing: Evaluating the impact of the 2008 Olympic Games on air quality
Air pollution Air quality
2015/9/21
To prepare for the 2008 Olympic Games, China adopted a number of radical measures
to improve air quality. Using the officially reported air pollution index (API) from 2000 to
2009, we show that thes...
This paper proposes a method of valuing air quality based on differences in
wages among cities. Using an urban location model it is shown that the supply of
labor to any city increases with the real...
