摘要： 非海盐硫酸根(nssSO42-)和甲基磺酸(MSA)是极地气溶胶和雪冰介质中主要的含硫化合物。空间尺度上, 南半球nssSO42-和MSA具有明显的纬度效应特征; 时间尺度上, nssSO42-和MSA具有季节变化特征(夏高冬低), 南极冰芯中MSA和nssSO42-浓度均在冰期增大, 北极冰芯记录出现MSA浓度在冰期减小、但是nssSO42-浓度在冰期仍然增大的现象。利用极地nssSO42-和MSA可以指示海洋初级生产力、大气温度、海冰范围变化以及人类活动影响等气候环境信息, 并对利用nssSO42-和MSA开展全球变化研究进行了展望。

Abstract: The main sulfur compounds of polar aerosols and snow-ice media are nssSO42− and MSA. Spatially, nssSO42− and MSA have obvious latitude effect characteristics. Temporally, nssSO42− and MSA have interannual variation  characteristics (high in summer and low in winter). The concentrations of nssSO42− and MSA in Antarctica ice cores increased during glacial periods, whereas the MSA concentration of Arctic ice cores decreased during glacial periods, although the nssSO42− concentration still increases during glacial periods. Both nssSO42− and MSA can be used to infer climate and environmental information such as marine primary productivity,atmospheric temperature, changes in sea ice extent and human influence. The prospect of using nssSO42− and MSA to study global change is also discussed.
