ACPD - Special IssueRegional formation processes and controlling effects of air pollution before and during the Beijing Olympics: the results of CAREBEIJING
Editor(s): D. Parrish, M. Gauss, T. Zhu, and U. PöschlMore Information Beijing as a megacity has experienced fast economical and social developments in the last decades. With the air pollution control efforts in recent years, the air quality in Beijing has been improved significantly. Yet this improvement was undermined by rapid increases in the number of vehicles and energy consumption in Beijing, and the regional transport of air pollutants from the surrounding heavy industrialized regions. For the 2008 Olympics, air pollution in Beijing was a serious concern.
In order to understand the transport and transformation processes of the regional air pollution in Beijing and surrounding region, and to formulate air pollution control strategies for the 2008 Beijing Olympics, Peking University initialized and organized an international collaborative project, CAREBEIJING (Campaigns of Air Quality Research in Beijing and Surrounding Regions). Field campaigns were conducted in 2006, 2007, and 2008, with the participation of more than 200 scientists and students from 21 research institutes.
The major findings of the CAREBEIJING studies about the transport and transformation processes of the regional air pollution in Beijing and surrounding region as well as air pollution controll results during the 2008 Beijing Olympics will be reported in this special issue.
