硫磺气溶胶影响人类健康、生态系统、农业以及全球和区域气候。利用自下而上的质量平衡法，根据国家一级的清单数据，编制了新的全球和区域人为二氧化硫排放量年度估计数，时间跨度为1850-2005年。全球排放量在20世纪70年代初达到峰值，并在2000年之前下降，近年来由于中国、国际航运和一般发展中国家的排放量增加而有所增加。进行了不确定性分析，包括随机不确定性和系统性不确定性。全球二氧化硫排放的总体不确定性相对较小，但地区不确定性高达30%。目前造成不确定性的最大因素是中国的排放和国际航运。排放在0.5度网格上逐区分布，用于协调的气候模型实验。
Sulfur aerosols impact human health, ecosystems, agriculture, and global and regional climate. A new annual estimate of anthropogenic global and regional sulfur dioxide emissions has been constructed spanning the period 1850 2005 using a bottom-up mass balance method, calibrated to country-level inventory data. Global emissions peaked in the early 1970s and decreased until 2000, with an increase in recent years due to increased emissions in China, international shipping, and developing countries in general. An uncertainty analysis was conducted including both random and systemic uncertainties. The overall global uncertainty in sulfur dioxide emissions is relatively small, but regional uncertainties ranged up to 30%. The largest contributors to uncertainty at present are emissions from China and international shipping. Emissions were distributed on a 0.5 degrees grid by sector for use in coordinated climate model experiments.
