Numerous recent field studies have revealed that organic organic chemical species are a major component of atmospheric aerosols. It has been suggested that organic compounds also play an important role in direct radiative forcing, as cloud condensation nucleii, and as ice nucleii. In this project, measurements of several organic compounds will be made in cloud water and in aerosols near clouds and on the edges of pollutant plumes. These studies will be carried out in the Western Pacific during the spring of 2000 in the region of pollution and soil dust outflow from China and Japan. Measurements made during the "China Dust" study will include a suite of carboxylic acids, alcohols, and carbohydrates.

许多最近的实地研究表明，有机有机化学物质是大气气溶胶的主要组成部分。有人认为有机化合物也在直接辐射强迫中起重要作用，如云凝结核和冰核。在这个项目中，将对云水、云附近的气溶胶以及污染物羽流边缘的几种有机化合物进行测量。这些研究将于2000年春季在西太平洋中国和日本的污染和土壤沙尘流出区域进行。在“中国尘埃”研究期间进行的测量将包括一系列羧酸、醇和碳水化合物。
