摘要
非海盐硫酸根(nssSO_(4)^(2-))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nssSO_(4)^(2-)和MSA具有明显的纬度效应特征;时间尺度上,nssSO_(4)^(2-)和MSA具有季节变化特征(夏高冬低),南极冰芯中MSA和nssSO_(4)^(2-)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nssSO_(4)^(2-)浓度在冰期仍然增大的现象。利用极地nssSO_(4)^(2-)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nssSO_(4)^(2-)和MSA开展全球变化研究进行了展望。
The main sulfur compounds of polar aerosols and snow-ice media are nssSO_(4)^(2-)and MSA.Spatially,nssSO_(4)^(2-)and MSA have obvious latitude effect characteristics.Temporally,nssSO_(4)^(2-)and MSA have interannual variation characteristics(high in summer and low in winter).The concentrations of nssSO_(4)^(2-)and MSA in Antarctic ice cores increased during glacial periods,whereas the MSA concentration of Arctic ice cores decreased during glacial periods,although the nssSO_(4)^(2-)concentration still increases during glacial periods.Both nssSO_(4)^(2-)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 nssSO_(4)^(2-)and MSA to study global change is also discussed.
