Abstract

Opposite to greenhouse gases, sulphate aerosol particles are expected to cause climate cooling, but uncertainties exist about source variability and strength. We analysed an ice core from a European glacier to quantify source strengths of aerosol-borne sulphate over a 200-year period. Sulphate from emissions of SO 2 increased by more than an order of magnitude during this century. This anthropogenic source is responsible for about 80% of total sulphate in the industrial period, and reflects emissions of west European countries. In the pre-industrial period mineral dust was the dominant contributor, followed by sulphate from SO 2 emissions with volcanoes or biomass burning as possible sources.

高山冰芯大气硫酸盐的人为与自然来源

与温室气体相反，硫酸盐气溶胶粒子预计会导致气候变冷，但其源变率和强度存在不确定性。我们分析了来自欧洲冰川的冰芯，量化了200年来气溶胶携带的硫酸盐的来源强度。二氧化硫排放产生的硫酸盐在本世纪增加了一个数量级以上。在工业时期，这一人为来源约占总硫酸盐的80%，反映了西欧国家的排放。在工业化前时期，矿物粉尘是主要的贡献者，其次是火山或生物质燃烧产生的二氧化硫排放的硫酸盐。DOI: 10.1034 / j.1600 0889.1999.t01 - 4 - 00006. x

期刊介绍： Tellus B: Chemical and Physical Meteorology along with its sister journal Tellus A: Dynamic Meteorology and Oceanography, are the international, peer-reviewed journals of the International Meteorological Institute in Stockholm, an independent non-for-profit body integrated into the Department of Meteorology at the Faculty of Sciences of Stockholm University, Sweden. Aiming to promote the exchange of knowledge about meteorology from across a range of scientific sub-disciplines, the two journals serve an international community of researchers, policy makers, managers, media and the general public.
