极地气溶胶及雪冰中非海盐硫酸根与甲基磺酸时空分布及环境指示

The main sulfur compounds of polar aerosols and snow-ice media are nssSO^2–₄ and MSA. Spatially, nssSO^2–₄ and MSA have obvious latitude effect characteristics. Temporally, nssSO^2–₄ and MSA have interannual variation characteristics (high in summer and low in winter). The concentrations of nssSO^2–₄ 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^2–₄ concentration still increases during glacial periods. Both nssSO^2–₄ 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^2–₄ and MSA to study global change is also discussed.
