Experimental Study of Sulfur Oxidation Chemistry in Clouds in Eastern China

伴随着工业化进程，燃用高硫煤发电量的快速增长使中国成为世界上最大的二氧化硫排放者S。因此，中国的降水正变得越来越酸性，硫酸盐沉积通量正在达到几十年前在欧洲和美国预先监管的环境下才能经历的水平。顺风向有大量酸雨和硫酸盐沉积的前景也令韩国和日本等邻国以及北太平洋和美国西南部感到担忧。科罗拉多州立大学(CSU)的科学家们将与中国学术和研究机构合作，进行一项为期数年的大型酸雨研究。他们长期以来一直对云和云滴在将气相SO2转化为硫酸液滴方面所起的作用感兴趣。利用山上现有的研究站。在经常拦截云层的TAI(中国东部)，将开展实地活动，以阐明这些云化学系统中二氧化硫氧化的控制机制。该项目为密歇根州立大学的学生提供了一个重要的国际培训机会，并可能加强美国和中国的科学合作。

Rapid increases in electric power generation by combustion of high sulfur coal associated with industrialization have made China the world''s largest emitter of sulfur dioxide (SO2). As a consequence, precipitation in China is becoming increasingly acidic, and sulfate deposition fluxes are reaching levels previously only experienced many decades ago in pre-regulated European and U.S. settings. The prospect of significant downwind acid rain and sulfate deposition is also a concern to neighboring countries such as South Korea and Japan as well as the Northern Pacific and Southwestern United States. Colorado State University (CSU) scientists, who have a longstanding research interest in the role that clouds and cloud droplets play in transforming gas-phase SO2 into sulfuric acid droplets, are to team with Chinese academic and research institutions in a large, multi-year acid rain study. Taking advantage of an existing research station at Mt. Tai (eastern China) which often intercepts clouds, field campaigns designed to shed light on the controlling mechanisms of the oxidation of SO2 in these cloud chemical systems will be carried out. The project provides an important international training opportunity for CSU students and may enhance U.S.-China scientific collaborations.
